I want to use a javascript in my jsp page in order to insert value of the input box into a table row.
My Jsp Page:-
<html>
<head>
<meta http-equiv="Content-Type" content="text/html; charset=UTF-8">
<title>Title</title>
<script type="text/javascript">
function addData(){
var x = 1;
var a = document.getElementById('area').value;
var table = document.getElementByTagName('table')[0];
var row = table.insertRow(table.rows.length);
var cell1 = row.insertCell(0);
var cell2 = row.insertCell(1);
cell1.innerHTML = x++;
cell2.innerHTML = a;
}
</script>
</head>
<body>
<h2>Area...</h2>
Area: <input type="text" id="area" name="area" required/><label>sq. ft.
<button onclick="addData();">Add To Table</button>
</br></br>
<div>
<h2>Area Table...</h2>
<table border="1">
<tr>
<th>Section</th>
<th>Area</th>
</tr>
<tr>
<td>1</td>
<td>125.4485</td>
</tr>
</table>
</div>
</body>
</html>
Here i wanted to insert a row into a table from the input box. But the value is not being inserted.
Is there any problem in the code.
use the console developer tools of your browser, to see errors,
here is the error :
Uncaught TypeError: document.getElementByTagName is not a function
at addData (a.html:11)
at HTMLButtonElement.onclick (a.html:28)
which means javascript doesn't recognise this function , so you have to look , the right notation of the function which is
getElementsByTagName
Please correct the spelling getElementByTagName to getElementsByTagName
Typo
Try like this, TagName is the multiple selector.you are missing s
var table = document.getElementsByTagName('table')[0];
instead of
var table = document.getElementByTagName('table')[0];
function addData() {
var x = 1;
var a = document.getElementById('area').value;
var table = document.getElementsByTagName('table')[0];
var row = table.insertRow(table.rows.length);
var cell1 = row.insertCell(0);
var cell2 = row.insertCell(1);
cell1.innerHTML = x++;
cell2.innerHTML = a;
}
<h2>Area...</h2>
Area: <input type="text" id="area" name="area" required/><label>sq. ft.
<button onclick="addData();">Add To Table</button>
</br></br>
<div>
<h2>Area Table...</h2>
<table border="1">
<tr>
<th>Section</th>
<th>Area</th>

<tr>
<td>1</td>
<td>125.4485</td>
</tr>

I am trying to create a web page where user can create his own schedule. User can enter the values of lines and columns in some input to build a table in which the user will write his schedule. I use this javascript code:
var p = document.getElementById('paragraph');
var table = document.createElement('table');
var tbody = document.createElement('tbody');
table.appendChild(tbody);
for (let i = 0; i < lines; i++){
let tr = document.createElement('tr');
for (let j = 0; j < columns; j++){
let td = document.createElement('td');
}
tbody.appendChild(tr);
}
p.appendChild(table);
However, when I'am trying to add information to table cells, I can't write values to each of them. I've used .innerHTML but it doesn't work the way it needs to. The information will be written only to the beginning of the table.
Should I give id to each td and then address to them by id when I need to write the information? Or there is another way to write values to table cells?
I think you need something like this to insert the data.
We have insertRow(), which is pre-defined function which i used in this answer to insert new row and then inserted columns in it with insertCell function.
<!DOCTYPE html>
<html>
<body>
<div class="inputs">
<input type="text" id="input1" placeholder="Enter first col data" >
<input type="text" id="input2" placeholder="Enter second col data" >
</div>
<br> <br> <br>
<table id="myTable">
<thead style="background-color: beige;">
<tr>
<td>default head row cell 1</td>
<td>default head row cell 2</td>
</tr>
</thead>
<tbody></tbody>
</table>
<br>
<button type="button" onclick="myFunction()">add data to body row</button>
<script>
function myFunction() {
var table = document.querySelector("#myTable tbody");
var row = table.insertRow();
var cell1 = row.insertCell(0);
var cell2 = row.insertCell(1);
const val1 = document.getElementById('input1').value;
const val2 = document.getElementById('input2').value;
cell1.innerHTML = val1;
cell2.innerHTML = val2;
}
</script>
</body>
</html>
I think that you need to refer to your button in the js file and write a function that will be executed on the "onclick" event
In this function, you are accessing the table variable. By using the built in javaScript function «insertRow()» you are adding rows to your table. Then you should add cells to this row in which information that users entered will be stored. This you can also do by using build in function «insertCell()»
Next, you access the fields in which the user has entered data
Retrieve values using the «value» built-in function
Using the built-in «innerHTML» function, draw cells with the information that you received in the previous step
You can look at the written code below for better assimilation of information
<!DOCTYPE html>
<html>
<body>
<div class="inputs" >
<input type="text" id="firstColumn" placeholder="Enter data here" >
<input type="text" id="SecondColumn" placeholder="Enter data here" >
</div>
<table id="Table">
<thead>
<tr>
<td style="background-color: pink;">Name of first column</td>
<hr>
<td style="background-color: purple;">Name of second column</td>
</tr>
</thead>
<tbody></tbody>
</table>
<br>
<button style="background-color: yellow;" type="button" id = "btn">Add</button>
<script>
const button = document.querySelector('#btn');
btn.onclick = function() {
var table = document.querySelector("#Table tbody");
var row = table.insertRow();
var Fcell = row.insertCell(0);
var Scell = row.insertCell(1);
const Fdata = document.getElementById('firstColumn').value;
const Sdata = document.getElementById('SecondColumn').value;
Fcell.innerHTML = Fdata;
Scell.innerHTML = Sdata;
}
</script>
</body>

I want to add a new row to a table. Therefore I have tried it in two different ways. In my opinion both should work. But indeed the don't. The first approach does not work. But why?
First approach (not working...):
<!DOCTYPE html>
<html lang="en">
<head>
<meta charset="utf-8">
<title>Table</title>
<script type="text/javascript">
function addLine(nr, name, date) {
var neueZeile = document.createElement("tr");
var neuerEintrag1 = document.createElement("td");
var neuerText1 = document.createTextNode(nr);
var neuerEintrag2 = document.createElement("td");
var neuerText2 = document.createTextNode(name);
var neuerEintrag3 = document.createElement("td");
var neuerText3 = document.createTextNode(date);
neuerEintrag1.appendChild(neuerText1);
neuerEintrag2.appendChild(neuerText2);
neuerEintrag3.appendChild(neuerText3);
neueZeile.appendChild(neuerEintrag1);
neueZeile.appendChild(neuerEintrag2);
neueZeile.appendChild(neuerEintrag3);
var parentN = document.getElementById("myTable");
parentN.appendChild(neueZeile);
</script>
<link rel="stylesheet" type="text/css" href="Website.css" />
</head>
<body>
<table class="table" id="myTable">
<thead>
<td>Nr.</td>
<td>Name</td>
<td>Datum</td>
</thead>
<tr>
<td>1</td>
<td>Max</td>
<td>01.01.2001</td>
</tr>
</table>
<form name=addRow>
Nr.:
<input type=text name=btn1>
Name:
<input type=text name=btn2>
Date:
<input type=text name=btn3>
<input type=button name=btn4 value=ADD
onclick="addLine(btn1.value,btn2.value,btn3.value)">
</form>
<input type=button name=btn5 value=DeleteLastAddedRow onclick="deleteRow()">
<a class="back" href="Website.html">Zurück</a>
</body>
</html>
My approach is not working. Does somebody know why or can help me?
Second approach (works fine...):
function addLine(nr, name, date) {
var table = document.getElementById("myTable");
var row = table.insertRow();
var cell1 = row.insertCell(0);
var cell2 = row.insertCell(1);
var cell3 = row.insertCell(2);
cell1.innerHTML = nr;
cell2.innerHTML = name;
cell3.innerHTML = date;
}
I am really interested in why the the first approach is not working.
Does somebody have an idea?
Kind regards
You missed to create tr element. Create tr and append it to table then all td to new tr.
Here is working code
function addLine(nr, name, date) {
var neuerEintrag1 = document.createElement("td");
var neuerText1 = document.createTextNode(nr);
var neuerEintrag2 = document.createElement("td");
var neuerText2 = document.createTextNode(name);
var neuerEintrag3 = document.createElement("td");
var neuerText3 = document.createTextNode(date);
neuerEintrag1.appendChild(neuerText1);
neuerEintrag2.appendChild(neuerText2);
neuerEintrag3.appendChild(neuerText3);
var parentN = document.getElementById("myTable");
var row = document.createElement("tr");
parentN.appendChild(row);
row.appendChild(neuerEintrag1);
row.appendChild(neuerEintrag2);
row.appendChild(neuerEintrag3);
}
<table class="table" id="myTable">
<thead>
<td>Nr.</td>
<td>Name</td>
<td>Datum</td>
</thead>
<tr>
<td>1</td>
<td>Max</td>
<td>01.01.2001</td>
</tr>
</table>
<form name=addRow>
Nr.:
<input type=text name=btn1> Name:
<input type=text name=btn2> Date:
<input type=text name=btn3>
<input type=button name=btn4 value=ADD onclick="addLine(btn1.value,btn2.value,btn3.value)">
</form>
I want to add edit and remove buttons in the third row of the table below whenever a row is added to the table. When the user user click edit, the columns cells becomes editable based on their original type (text-box and drop-down menu) and allow editing. In addition, the edit button adds a new save button after the user clicks the edit button. When the user clicks delete, the row gets deleted. I have seen a lot of previous posts but I want to use HTML and Javascript-only unless if it is not possible at all (some solutions recommend external libraries and some use JQuery).
I tried several ways with no success. I will be thankful to any pointer or code snippet that simplifies this task for me.
I have a database where I get and store data to but I am simplifying the code with arrays as follows.
HTML:
<html>
<head>
<meta charset="UTF-8">
</head>
<body id="body">
<div id="wrapper">
<table align='center' cellspacing=1 cellpadding=1 id="mytable" border=1>
<tr>
<th>Name</th>
<th>Type</th>
<th>Action</th>
</tr>
<tr>
<td><input type="text" id="text"></td>
<td>
<select name="levels" id="levels">
<option value="A" id="option-1">A</option>
<option value="B" id="option-2">B</option>
<option value="C" id="option-3">C</option>
</select>
</td>
<td><input type="button" class="add" id="add-button" value="Add"></td>
</tr>
</table>
</div>
<script src="get-text.js"></script>
</body>
</html>
Script:
var myArray = [{"name":"aaa","level":"A"},{"name":"bbb","level":"B"},{"name":"ccc","level":"C"}];
//to display stored data in the table
function display()
{
var table=document.getElementById("mytable");
var length=myArray.length;
for(var i=0; i<length; i++)
{
var row = table.insertRow(i+1);
var cell1 = row.insertCell(0);
var cell2 = row.insertCell(1);
var cell3 = row.insertCell(2);
cell1.innerHTML = myArray[i].name;
cell2.innerHTML = myArray[i].level;
}//end for
} //end display
display(); //call display.
var addButton=document.getElementById("add-button");
//listen to add button. If clicked, store the entered data and append them in the display
addButton.addEventListener('click', function (){
event.preventDefault();
//get the data from the form
var mytext = document.getElementById("text").value;
var mylevel = document.getElementById("levels").value;
//store the entered values into the array
myArray.name=mytext;
myArray.level=mylevel;
var length=myArray.length;
console.log("Array Length: "+length)
//add the entered data to the table.
var table=document.getElementById("mytable");
var newRow = table.insertRow(length+1);
var cell1 = newRow.insertCell(0);
var cell2 = newRow.insertCell(1);
var cell3 = newRow.insertCell(2);
cell1.innerHTML = mytext;
cell2.innerHTML = mylevel;
mytext.value = '';
}, false);

I am trying to something like this in my code. Add, Edit, Delete from Tables Dynamically but my attempts were not successful in this part.

I have added a row using javascript. Now I want the new columns's value to be picked from the input box text by id. There's some sort of error in it, which I'm unable to get.
<html>
<head>
<script>
function addtosubtotal() {
var table = document.getElementById("myTable");
var row = table.insertRow(2);
var cell1 = row.insertCell(0);
var cell2 = row.insertCell(1);
cell1.innerHTML = getElementById("cid");
cell2.innerHTML = document.getElementById("name");
}
</script>
</head>
<body>
<table id="myTable" >
<tr>
<td>S. No</td>
<td>Item Name</td>
<td>Subtotal</td>
</tr>
<tr>
<td><input type="text" id="cid" name="id" /> </td>
<td><button onclick="addtosubtotal()" /></td>
</tr>
</table>
</body>
</html>
You don't have an id for the input name:
<input type="text" id="name" name="name" />
So you wont get it by id
You can also combine the two statements in your JavaScript if you want to
<script>
function addtosubtotal() {
var table = document.getElementById("myTable");
var row = table.insertRow(2);
var cell1 = row.insertCell(0).innerHTML = document.getElementById("cid").value;
var cell2 = row.insertCell(1).innerHTML = document.getElementById("name").value;
}
</script>
Based upon user-input I want to generate a matrix / table for display. Here is the html
html
<meta http-equiv="Content-Type" content="text/html; charset=windows-1252"/>
<title>lostBondUserPmtEntry</title>
<body>
<form name="test" ><font face="Verdana" size = "2">
<input name="Text1" type="text" /> score <br>
<input type="submit" Name ="test" id="gp"/>
<input type="hidden" name="dateFactor">
<table border="1">
<tr>
<td>sensitivity level</td>
<td>criticality level</td>
<td>priority level</td>
<td>Response time</td>
</tr>
<tr>
<td>1</td>
<td>2</td>
<td>high</td>
<td>2 hours</td>
</tr>
</table>
</form>
</body>
DEMO
The brief algo is
if score is 10 (certain value) populate the table as with predefined values (those values with column names are shown in DEMO). I want the table to be generated on particular button. I can call function, but I want to know how to append the html code for table on function call.
Thanks.
To append a row to the table you can try something like this:
function addRow(tableID) {
var table = document.getElementById(tableID);
var rowCount = table.rows.length;
var row = table.insertRow(rowCount);
var cell1 = row.insertCell(0);
cell1.innerHTML = "cell 1 text";
var cell2 = row.insertCell(1);
cell2.innerHTML = "cell 2 text";
var cell3 = row.insertCell(2);
cell3.innerHTML = "cell 3 text";
}
