JQuery Read Rows And Columns Of HTML Table

JavaScript script below will read through all rows and display text in cells of columns in a HTML table.

Assume we have a HTML table id=example-table like this:

1
2
3
4
5
6
7
8
9
10
11
12
13
14

16
17
18

20

23

<table cellspacing="0" cellpadding="4" id="example-table">
	<tr style="color:White;background-color:#5D7B9D;font-weight:bold;">
		<th scope="col">No</th>
		<th scope="col">Friend Name</th>
		<th scope="col">Job Position</th>
		<th scope="col">Company</th>
		<th scope="col">Website</th>
	</tr>
	<tr style="color:#333333;background-color:#F7F6F3;">
		<td>1</td>
		<td>Hoan Huynh</td>
		<td>Developer</td>
		<td>4 Rapid Development</td>
		<td><a id='website_url_1' href='http://4rapiddev.com'>http://4rapiddev.com</a></td>
	</tr>
	<tr style="color:#284775;background-color:White;">
		<td>2</td>
		<td>Hoan Huynh</td>
		<td>General Director</td>
		<td>OPSgreat</td>
		<td><a id='website_url_2' href='http://opsgreat.com/'>http://opsgreat.com/</a></td>
	</tr>
</table>

The HTML table is like this:

<script type="text/javascript">
$(document).ready(function() {
	var table = document.getElementById('example-table');
 
	var rowLength = table.rows.length;
 
	var FriendList = "<ul>";
 
	var count = 0;
	for(var i=1; i<rowLength; i+=1){
		count ++;
		var row = table.rows[i];
 
		var FriendName = row.cells[1].innerHTML;
		var JobPosition = row.cells[2].innerHTML;
		var Company = row.cells[3].innerHTML;
		var WebsiteURL = document.getElementById('website_url_' + count);
 
		FriendList += "<li>" + FriendName + " is working for <a href='" + WebsiteURL + "'>" + Company + "</a> as " + JobPosition + "</li>";
	}
	FriendList += "</ul>";
	FriendList = "<p>We have: " + count + " friends in the list:</p>" + FriendList;
 
	$("#FriendList").html(FriendList);
});	
</script>

And the result is
