Hello everybody
I want to make my website faster so, i have decided to use Javascript validation.
I have created javascript validation. Validations are working properly in Firefox and chrome but it is not working in IE.

For e.g

JavaScript

 spfname.innerHTML = '<img src="img/true.png" alt="" /> Success';
fname.classList.remove('txt');
spfname.classList.remove('error-span');
fname.classList.add('success');
spfname.classList.add('success-span');
return true;

classList.remove property is working in firefox and chrome but it is not working in IE.
same way classList.add property.

Please reply me how to resolve this problem.

Thanks!
Shailesh.

Not working
What's the error message? Check with javascript debugger.

No error messages of course, just no effect of added/removed class.
I found alternative solution which works correctly, please see.

Hm! It just tried it, it's true!

My idea was to try jQuery. As I thought, the equivalent solution with jQuery worked correctly:

JavaScript

$(fname).removeClass('txt');
$(spfname).removeClass('error-span');
$(fname).addClass('success');
$(spfname).addClass('success-span');

Please try it — jQuery is written with compatibility in mind. I did not look how jQuery works around the problem in JavaScript code, but it certainly works the same way on the Browsers I tested: Mozilla Seamonkey vs. IE vs. Google Chrome.

[EDIT]

I don't see initialization of the variables fname and spfname in your code but assumed they are objects correctly representing DOM elements, so they could serve as valid parameters to the jQuery $() function, which can also accept different types of parameters (selectors using IDs, classes, XPath queries and the combinations of those) and return jQuery wrapper objects representing a set of DOM elements, with a number of functions.
