Highlighting Table Data Fields When User Doesnt Enter Data To A Text Box

[Thimali]

Hi all,
I have a web page which is having a text box.I have already validated this using java script.Now i want to validate this same text box without prompting the error message.I need to change the corresponding table data field colour in to red(which would indicate the place which user doesn't have entered value)
If anybody is having an idea pls share with me.
Thx
Thimali

Post what code you have so far. Do you want to change the background colour?

Heya, Thimali. Welcome to TSDN!

Simply change the element's background color:

document.getElementById('idOfElementGoesHere').style.backgroundColor = '#ff9999';

    obj.style.backgroundColor="red";
}
 
<input type="text" onblur="example(this);">
