I am trying to implement a dynamic table but when the button is pressed to add a row the row is added but the input text box is not inserted in both cells. Any idea how to solve this problem.
<html>
<body>
<input type="button" value="Add Row" onclick="addRow('dataTable')" />
<table id="dataTable" width="150px" border="1">
<tr>
<td height="27">
1
</td>
<td>
<input type="text" />
</td>
<td>
<input type="text" />
</td>
</tr>
</table>
</body>
</html>
<script type="text/javascript">
function addRow(tableID) {
var table = document.getElementById(tableID);
var rowCount = table.rows.length;
var row = table.insertRow(rowCount);
var firstCell = row.insertCell(0);
firstCell.innerHTML = rowCount + 1;
var secondCell = row.insertCell(1);
var thirdCell = row.insertCell(2);
var element = document.createElement("input");
element.type = "text";
element.name = "txtbox[]";
secondCell.appendChild(element);
}
</script>
You need to add another "input" element and append this into the thirdCell.
Try changing the last bit of your javascript function to this:
var element1 = document.createElement("input");
element1.type = "text";
element1.name = "txtbox1[]";
var element2 = document.createElement("input");
element2.type = "text";
element2.name = "txtbox2[]";
secondCell.appendChild(element1);
thirdCell.appendChild(element2);
Shown here
Note: Your script tag should go inside the body of the html.
Here is what the final code could look like:
<html>
<body>
<input type="button" value="Add Row" onclick="addRow('dataTable')" />
<table id="dataTable" width="150px" border="1">
<tr>
<td height="27">
1
</td>
<td>
<input type="text" />
</td>
<td>
<input type="text" />
</td>
</tr>
</table>
<script type="text/javascript">
function addRow(tableID) {
var table = document.getElementById(tableID);
var rowCount = table.rows.length;
var row = table.insertRow(rowCount);
var firstCell = row.insertCell(0);
firstCell.innerHTML = rowCount + 1;
var secondCell = row.insertCell(1);
var thirdCell = row.insertCell(2);
var element1 = document.createElement("input");
element1.type = "text";
element1.name = "txtbox1[]";
var element2 = document.createElement("input");
element2.type = "text";
element2.name = "txtbox2[]";
secondCell.appendChild(element1);
thirdCell.appendChild(element2);
}
</script>
</body>
</html>
You have not written the code to add a new text element to the third column. Add the below mentioned code after "secondCell.appendChild(element);" section of your code:
var element2 = document.createElement("input");
element2.type = "text";
element2.name = "txtbox2[]";
thirdCell.appendChild(element2);

Are you expecting something like this?
I am making the subject code field readonly after the user changes it using JQuery change event.
function addRow(tableID) {
var table = document.getElementById(tableID);
var rowCount = table.rows.length;
var row = table.insertRow(rowCount);
var cell1 = row.insertCell(0);

if (null != chkbox && true == chkbox.checked) {

I was trying to make a delete button to delete rows or using chkbox and button to delete rows. When I use the deleteRow function, it will delete all rows in the table. Also, I have assigned an element id to do other functions, so I cannot change the addrow function about assign element id.
When i use delete button, it can do i wanted. I want to delete the row when the checkbox checked How can i use checkbox to delete row ?
Here's my code:

<form>
<table>
<tr>
<td align="center" colspan="3"></td>

<td align="center"><b>Product ID:</b></td>
<td><input type="text" name="productid" id="productid" class="form-control" /></td>
<td align="center"><b>QTY:</b></td>
<td><input type="text" name="poqty" id="poqty" class="form- control"></td>
</tr>
<tr>
<input type="button" value="Add Item" onclick="addRow('dataTable')" class="form-control" />
<input type="button" value="del Item" onclick="deleteRow('dataTable')" class="btn btn-default" />

<input type="submit" value="confirm">

<div id="txtHint"></div>

var table = document.getElementById(tableID);

var cell1 = row.insertCell(0);
var element1 = document.createElement("input");
element1.type = "checkbox";
element1.name = "chkbox";
element1.id = "chkone" + y;
cell1.appendChild(element1);
var cell2 = row.insertCell(1);
var element2 = document.createElement("input");

element2.name = "txtbox1[]";
element2.id = "txtone" + y;
cell2.appendChild(element2);
var cell3 = row.insertCell(2);
var element3 = document.createElement("input");
element3.type = "text";

I want to delete the row when the checkbox checked , How can i use checkbox to delete row ?
There's probably more than one problem here, but what sticks out to me is this:
<input type="button" value="Add Item" onclick="addRow(tableID)" class="form-control" />
It doesn't look like you're correctly passing tableID to this function, whereas you're correctly passing a parameter to the deleteRow() function. Where is tableID in your code?
Given the code you've posted, nothing happens when you invoke addRow() because the function is never fired - tableID is undefined.
I have this javascript function:
function addItem(tableID){
var table = document.getElementById(tableID);
var rowCount = table.rows.length;
var row = table.insertRow(rowCount);
var cell1 = row.insertCell(0);
var element1 = document.createElement("input");
element1.type = "checkbox";
element1.name="checkbox[]";
cell1.appendChild(element1);
var cell2 = row.insertCell(1);
var element2 = document.createElement("input");
element2.type = "text";
element2.name = "textbox[]";
cell2.appendChild(element2);
var cell3 = row.insertCell(2);
var element3 = document.createElement("input");
// *****I DO NOT KNOW WHAT GOES HERE*****
cell3.appendChild(element3);
}
I also have an HTML file that where it looks like this:
<header>
<div id="header-left">
<input type="checkbox" id="select-all"></input>
<label for="select-all" id="select-all-tag"> Select All </label>
</div>
<h1> TODO </h1>
<div id="header-right">
<button id="sort-by">Sort By</button>
<button id="add-new" onclick="addItem('todoTable')">Add</button>
</div>
</header>
<table id="todoTable" border="1">
<tr>
<td><input type="checkbox" name="checkbox"/></td>
<td><input type="text" /></td>
<script>
$(function() {
$(".date-picker").datepicker();
});
</script>
<td><input type="text" name="date[]" class="date-picker datepicker"></td>
</tr>
</table>
The HTML file creates the sort of row that I want. For the JavaScript, I am trying to add a row with a datepicker in the third cell, but I do not know how. So, how do I have a datepicker show in the third cell in JavaScript? Please let me know if you need clarification.
So long as you have the appropriate scripts included, this should suffice:
var cell3 = row.insertCell(2);
var element3 = document.createElement("input");
$(element3).datepicker();
I am new in javascript and I want to generate rows dynamically when "Tab" is pressed and want to get the values enterd in dynamically generated rows so that i could use these values in my servlet code.
Here is my html
<html>
<head>
<title> Add/Remove dynamic rows in HTML table </title>
<script src="table.js" language="javascript" /></script>
</head>
<body onload="hello()">
<form action="servletname">
<input type="button" value="Delete Row" onclick="deleteRow()" />
<table id="table1" width="350px" border="2">
<tr>
<td align="center"> Sr.No </td>
<td align="center" style="width:50px;"> Code </td>
<td align="center" style="width:1100px;"> Test Name </td>
<td align="center" style="width:80px;"> Rate </td>
</tr>
</table>
<table id="table2" width="350px" border="2">
<tr>
<td><input type="checkbox" name="chk"/></td>
<td> 1 </td>
<td> <input type="text" id="tc" style="width:50px;" /> </td>
<td> <input type="text" id="tn" style="width:190px;" /> </td>
<td> <input type="text" id="rt" style="width:80px;" onkeypress="KeyCheck(event)" /> </td>
</tr>
</table>
<br><input type="text" id="rt1" style="width:80px;"/>
</form>
</body>
</html>
code of "row.js" file is:
function hello()
{
document.getElementById("tc").focus();
}
function KeyCheck(e)
{
var KeyID = (window.event) ? event.keyCode : e.keyCode;
if(KeyID==9)
{
addRow();
}
}
function addRow()
{
var table = document.getElementById("table2");
var rowCount = table.rows.length;
var row = table.insertRow(table.rows.length);
var cell1 = row.insertCell(0);
var element1 = document.createElement("input");
element1.type = "checkbox";
cell1.appendChild(element1);
var cell2 = row.insertCell(1);
cell2.innerHTML = rowCount + 1;
var cell3 = row.insertCell(2);
var element2 = document.createElement("input");
element2.type = "text";
element2.style.width = "50px";
cell3.appendChild(element2);
var cell4 = row.insertCell(3);
var element3 = document.createElement("input");
element3.type = "text";
cell4.appendChild(element3);
var cell5 = row.insertCell(4);
var element4= document.createElement("input");
element4.type = "text";
element4.style.width = "80px";
cell5.appendChild(element4);
element4.focus(); // to shift focus on last cell in newly generated row
//to generate new row if enter is pressed in focused cell of newly generated row.
element4.onkeypress=KeyCheck;
}
But it doesnot detect "Tab" or any other key except than "Enter" key. plz tell me how to detect "Tab" or some other key in this program and how can I access values entered in these dyanamically generated rows.
Use the following js function for add row:
function addRow() {
var table = document.getElementById("table2");
var rowCount = table.rows.length;
var row = table.insertRow(table.rows.length);
var cell1 = row.insertCell(0);
var element1 = document.createElement("input");
element1.type = "checkbox";
cell1.appendChild(element1);
var cell2 = row.insertCell(1);
cell2.innerHTML = rowCount + 1;
var cell3 = row.insertCell(2);
var element2 = document.createElement("input");
element2.type = "text";
element2.style.width = "50px";
cell3.appendChild(element2);
var cell4 = row.insertCell(3);
var element3 = document.createElement("input");
element3.type = "text";
cell4.appendChild(element3);
var cell5 = row.insertCell(4);
var element4 = document.createElement("input");
element4.type = "text";
element4.style.width = "80px";
element4.onkeypress = KeyCheck;
cell5.appendChild(element4);
element4.focus();// to shift focus on last cell in newly generated row
//to generate new row if enter is pressed in focused cell of newly generated row.
}
You're setting up the event handler incorectly. It should be:
element4.onkeypress=KeyCheck
http://jsfiddle.net/SMDhu/4/
For Tab key you need to handle keydown with keycode 9.
To get the value inside the value inside the field, simply access the value property of the DOM element.

This the code for adding row dynamically
This is the code for calendar
<script language="JavaScript" src="calendar_us.js"></script>
<link rel="stylesheet" href="calendar.css">
<INPUT type="text" name="testinput" />
<script language="JavaScript">
new tcal ({
// form name
'formname': 'testform',
// input name
'controlname': 'testinput'
});
</script>
add a new cell for example,
var cell4 = row.insertCell(3);
cell4.innerHTML = new Date();
.
<TR>
<TD><INPUT type="checkbox" name="chk"/></TD>
<TD> 1 </TD>
<TD> <INPUT type="text" /> </TD>
<TD> <INPUT type="text" name="testinput" /></TD>
</TR>
can you explain where to insert the date?
