Question

Using Share Point Designer 2010.

I want to conduct client side validation (jquery) but I don’t know how to run my code before the form gets submitted. The reason for this is my form has jquery that hides/shows certain fields . So different fields are mandatory depending on client side selection.

Originally I tried to do this with the built in server sided validation but they cannot handle conditional validation, I don’t think.

I believe this bit of JavaScript may help, assuming you have jQuery loaded as well:

$("#btnSubmit").click(function(){
  return formIsValid(); //formIsValid returns false then the form is not submitted, if true then the submission continues
});
