maxlength of textbox is not working in javascript

[engineer]

Hi,
I'm trying to control the maxlength property of a textbox in javascript. But it's not going into effect.This is my code

HTML

<input type=text id="txt_search_string" class=formtext maxlength=100 />
 

JavaScript

if(var_selection = 'C')
   document.getElementById('txt_search_string').MaxLength = '6' ;
else if (var_selection = 'D')
   document.getElementById('txt_search_string').MaxLength = '12' ;
 

There's nothing wrong in the syntax as I checked it and there are no errors either. It looks fine except the maxlength going into effect. Your help greatly appreciated.

Heya, engineer. Welcome to TSDN!

Please use CODE tags when posting source code. See the REPLY GUIDELINES on the right side of the page next time you post.

Try using

document.getElementById('txt_search_string').setAttribute('maxlength', 6);

You could also use the maxLength property.
