How to let Validation control and custom javascript validation function work together?

Question

I'm developing a web application. At first I use validation control to do required field validation, later I need to add some custom function to do the validation but still need required field validation. The problem is I found after I add onclientcliek event of the submit button, the previous validation control does not fired. Is there a way that could let both the validation control and my javascript function work before submit the form? Thank you for your time.

Answer 1

make sure you have an ID on your submit button and try and put something like this in your document.ready function:

$("#YourSubmitButtonId").click(function(){
       yourValidationFunction();
       return false;
 });

Answer 2

Use CustomValidator Control. It is pretty easy to configure your own Client-side Validation. More info and an example here . Both validation controls can then work side by side.
