Delete all regular rows of an HTML table
Solution: Your problem is that when you remove row 1, row 2 becomes the new row 1 and you move to the next row, deleting row 2 (which was the original row 3). In my original code, it’s not included in here, I can browse through different tables and I want to be able to delete all of its content, regardless of number of row, using the same button.
Delete all regular rows of an HTML table
I have this button that’s supposed to delete all the rows inside a table except for the header. As of now, it loops through the table to delete all its row, but it never deletes all of it. In my original code, it’s not included in here, I can browse through different tables and I want to be able to delete all of its content, regardless of number of row, using the same button. Coz I also try the button on other tables and it always does not delete all he items.
let mealObj = < menu1: < menuName: "Steak", ingr1: < name: "Butter", ingrType: "other", amount: "2", amountType: "tbsp", cal: "10", >, ingr2: < name: "Parsley", ingrType: "vegetable", amount: "1", amountType: "tsp", cal: "1", >, ingr3: < name: "Garlic", ingrType: "vegetable", amount: "1/2", amountType: "tsp", cal: "20", >, ingr4: < name: "Soy Sauce", ingrType: "other", amount: "1/4", amountType: "tsp", cal: "20", >, ingr5: < name: "Beef", ingrType: "meat", amount: "3/4", amountType: "lbs", cal: "200", >, ingr6: < name: "Salt", ingrType: "other", amount: "1/8", amountType: "tsp", cal: "0", >, ingr7: < name: "Pepper", ingrType: "other", amount: "1/8", amountType: "tsp", cal: "2", >, >, > let ingrTable = document.getElementById("ingr-table"); objToTable(mealObj); function objToTable(ingrList) < let totalRowLength = ingrTable.rows.length; for (let i in ingrList) < for (let k in ingrList[i]) < if (ingrList[i][k].name !== undefined) < let tableAmount = document.createElement("INPUT"); tableAmount.setAttribute("type", "number"); tableAmount.id = "table-amount"; let tableCalNum = document.createElement("INPUT"); tableCalNum.setAttribute("type", "number"); tableCalNum.id = "table-cal"; let row = ingrTable.insertRow(totalRowLength); var cell1 = row.insertCell(0); var cell2 = row.insertCell(1); var cell3 = row.insertCell(2); var cell4 = row.insertCell(3); var cell5 = row.insertCell(4); cell1.innerHTML = ingrList[i][k].name; cell2.appendChild(tableAmount); tableAmount.value = eval(ingrList[i][k].amount); cell3.innerHTML = ingrList[i][k].amountType; cell4.appendChild(tableCalNum); tableCalNum.value = ingrList[i][k].cal; >> > > let button = document.getElementById("button"); let deleteBtn = document.createElement("BUTTON"); deleteBtn.innerHTML = "Delete"; button.appendChild(deleteBtn); deleteBtn.addEventListener("click", function () < for (let i = 0; i < ingrTable.rows.length; i++) < ingrTable.deleteRow(i + 1); >>); Ingredient Amount Calorie Your problem is that when you remove row 1, row 2 becomes the new row 1 and you move to the next row, deleting row 2 (which was the original row 3).
One way to solve this is to start by removing the last row and work back to the beginning
deleteBtn.addEventListener("click", function () < for (let i = ingrTable.rows.length - 1; i >0; i--) < ingrTable.deleteRow(i); >>); An alternative, faster method is to replace the html with the headers only instead of removing all rows:
deleteBtn.addEventListener("click", function () < ingrTable.innerHTML = ingrTable.rows[0].innerHTML >); Javascript — Cypress — delete all rows from table, With this recursive function you just need to pass a variable that decrements (or maybe increments to a max)

How to delete all rows on click in a dynamic table using reactjs
Currently when the delete button is clicked it only deletes one row at a time. However, my current aim is for it do delete all rows at the same time but I the solutions I have tried do not work. Here is the current code:
const [shop, setShop] = useState([]); . const [count, setCount] = useState(0); . const handleDelete = (shopsId) => < const newArr = [. shop]; const index = shop.findIndex((shop) =>shop.id === shopsId); newArr.splice(index, 1); setShop(newArr); setCount(count - count) > This method is successful if I want to remove a specific row however I do not want to do this but instead Remove all the rows (‘delete all’). Any help would be appreciated.

Automatically Delete table rows after reaching row limit and add new data to the row using the Websocket data with javascript
I am new to JavaScript, not sure if this very basic question. I’ve created a Bitcoin Price update dashboard using the data fetched from the external WebSocket. I managed to get the data from the WebSocket and display it on the HTML table. The price updates every seconds, So the table rows are going insane. I want to limit the Table row for 14 rows and after the table get 14 rows i want to delete that data and import new data with the Websocket without increasing the HTML table rows. I tried my best to explain.
I have provided the code snippets below as well as external Websocket from where I am pulling the data.
Please let me know how should I insert the row dynamically into a HTML table. Thank you so much in advance

You can get all rows in your table using querySelectorAll(«tr») . You can remove elements from your table using removeChild .
So, to make sure your table never grows past x rows, you do:
const rows = table.querySelectorAll("tr"); if (rows.length > 14) table.removeChild(rows[0]); window.onload = () => < function insertRow(price) < var tr = document.createElement("tr"), tdCoin = document.createElement("td"), tdPrice = document.createElement("td"), docFrag = new DocumentFragment(); tdCoin.textContent = "BTC"; tdPrice.textContent = `$`; tr.appendChild(tdCoin); tr.appendChild(tdPrice); docFrag.appendChild(tr); return docFrag; > var binanceSocket = new WebSocket("wss://stream.binance.com:9443/ws/btcusdt@trade"), table = document.getElementById("pricetable"); binanceSocket.onmessage = function(event) < var messageObject = JSON.parse(event.data); table.appendChild(insertRow(messageObject.p)); const MAX_ROWS = 5; const rows = table.querySelectorAll("tr"); if (rows.length >MAX_ROWS) table.removeChild(rows[0]); > >How to remove the table row in a table using JavaScript, The remove() method is used to remove the table row from an HTML table using JavaScript. remove() Method: This method removes the selected
Delete all rows in an HTML table
This way, you could target the rows within the body and remove them whilst preserving your (sibling node to ): body.removeChild(rowsWithinBody) https://developer.mozilla.org/en-US/docs/Web/HTML/Element/tbody#examples Solution 4: with jQuery you can do it simply in a single line of code.

How to remove specific row in table using js
I am learning javascript and i made this simple page where you add your title and author. By clicking on add button the input is entered to table where you have remove button. How can i implement a function remove()<> in javascript that removed the row of the table from where it was called, because i tried using output.lastElement.remove(); but that only removes the last row not the row from where the button is clicked. If you know how can i make this please give me an answer ty :).
var title = document.getElementById("title"); var author = document.getElementById("author"); var output = document.getElementById("output"); function addToTable()< output.innerHTML += "" + "" + title.value + " " + "" + author.value + " " + "" + ""+ " " + " " > function remove() label < width: 100px; display: inline-block; >table,th,td,tr,td < border: 1px solid black; border-collapse: collapse; >table td
Title Author Button
Just throw this to remove function as parametr and then call removeChild on parent.
var title = document.getElementById("title"); var author = document.getElementById("author"); var output = document.getElementById("output"); function addToTable()< output.innerHTML += "" + "" + title.value + " " + "" + author.value + " " + "" + ""+ " " + " " > function remove(btn) label < width: 100px; display: inline-block; >table,th,td,tr,td < border: 1px solid black; border-collapse: collapse; >table td
Title Author Button
Using modern javascript syntax:
const title = document.getElementById("title"); const author = document.getElementById("author"); const output = document.getElementById("output"); const addToTable = () => < const dataId = `table-row-$`; output.innerHTML += ` $ $ ')" value="Remove"> `; > const remove = (dataRowID) => < output.querySelector(`[data-row-id="$"]`).remove(); >
label < width: 100px; display: inline-block; >table, th, td, tr, td < border: 1px solid black; border-collapse: collapse; >table td
Title Author Button
I advise you not to completely use old javascript syntax.
An example using event delegation.
function addToTable() < const title = document.getElementById("title"); const author = document.getElementById("author"); const output = document.getElementById("output"); output.innerHTML += "" + "" + title.value + " " + "" + author.value + " " + "" + "" + " " + " "; > function removeRow(e) < if (e.target.tagName === "BUTTON") < e.target.closest("tr").remove(); >> document.querySelector("#output").addEventListener("click", removeRow);
label < width: 100px; display: inline-block; >table,th,td,tr,td < border: 1px solid black; border-collapse: collapse; >table td

How can I remove table borders with DocxJS?
Let’s say I want to remove all of the borders from this table:
Following the documentation online: https://docx.js.org/#/usage/tables
new Table(< borders: < top: , bottom: , left: , right: , >, rows: [ new TableRow(< children: [ new TableCell(< children: [ new Paragraph(< children: [some_image_file] >), ], >), new TableCell(< children: [ new Paragraph(< text: "text" >), ], >), ], >), ], >)
According to the documentation, moving the border options inside the TableCell should impact the cell’s borders, but I see no results when I do so. Any ideas how to achieve a table without any borders?
As mentioned by @cbloss793, It seems that border options for TableCell must also contain the size: 0 attribute to remove the corresponding border. I also added color: «FFFFFF» just to be safe.
. new TableCell(< borders: < top: , bottom: , left: , right: , >, .
Remove table row after clicking table row delete button, You can use jQuery click instead of using onclick attribute, Try the following: $(‘table’).on(‘click’, ‘input[type=»button»]’, function(e)
Delete all rows in an HTML table except for header with JS
So I am having trouble deleting all of the data in an HTML table with js WITHOUT deleting the header. Here is my HTML:
Binary Hex Assembly Description
var ab = ""; var row; var table = ['0000000000nopno operation', '0000000101ld (bc), **loads ** into BC']; var bin = ['00000000', '00000001']; var hex = ['00', '01']; var assembly = ['nop', 'ld (bc), **']; var description = ['no operation', 'loads ** into BC']; l = table.length; function find() < row = id.insertRow(0); for (i=0;i <=l-1;i++) < ab = table[i]; if (ab.includes(document.getElementById("input").value)) < row = id.insertRow(-1); cell1 = row.insertCell(0); cell2 = row.insertCell(1); cell3 = row.insertCell(2); cell4 = row.insertCell(3); cell1.innerHTML = bin[i]; cell2.innerHTML = hex[i]; cell3.innerHTML = assembly[i]; cell4.innerHTML = description[i]; >> >
I have omitted A LOT of array entries because they contained almost the FULL instruction set of thee z80 microprocessor. What this code does (basically) is it gets an input from the user and if the array table contains that input then it gets the corresponding values from bin , hex , assembly and description and assigns each a column in the table out , then adds a row with the for the data. However, I cannot seem to find a way to delete all of the rows in tbody before another set of values are appended to the table without deleting thead . I have searched around on the web and found several solutions, none of which worked. They either deleted the thead or caused some kind of error (I’ll give examples if you ask). I am using Google Chrome version 63.0.3239.132 web browser to run my code. As you may be able to see I am quite new to js and HTML Any ideas what I have done wrong?
First You have to close your
tag
This is how you can clear your table.

Assuming you want to keep the tbody element intact instead of just removing it and all its children at once:
// get a reference to the tbody element var tb = document.querySelector('#out tbody'); // while tb has children, remove the first one while (tb.childNodes.length) < tb.removeChild(tb.childNodes[0]); >// tb is now empty
From a semantic perspective, it would make the removal of rows much easier if you added them to the element instead of the element. This way, you could target the rows within the body and remove them whilst preserving your (sibling node to ):
var body = document.querySelector('tbody'); while (body.firstChild) < // This will remove all children within tbody which in your case are elements body.removeChild(body.firstChild); >
with jQuery you can do it simply in a single line of code.
it will remove all rows in a table except the header.
