How can I Validate forms with jquery

0 votes

Thanks to some awesome people on stack overflow i was able to get my classes toggled and got my form slide up and down correctly. I'm having issues validating the form before it becomes submitted. Could someone help me with a step in the right direction? I just want the validation to check that the fields have some text in them before allowing the submit. Assignment 6

        <h2>About this page layout:</h2>
        <p> The main container (parent) has 'relative' positioning so that the 'login' container can be absolutley positioned with respect to
          that main container. Otherwise, it would default to being absolutley positioned with respect to the window. </p>
        <p> In order for the login panel to be placed on top of the page  we need to use  absolute positioning, otherwise,
          it would move the rest of the content down as done in the FAQ assignment. Technically, absolute positioning takes that element out of
          the normal flow of the document, so that it is on top of the page. The 'ad' is also absolutely positioned to the same main container. </p>
      </section>

Then to define rules use simple syntax. jQuery(document). ready(function() { jQuery("#forms). validate({ rules: { firstname: 'required', lastname: 'required', u_email: { required: true, email: true,//add an email rule that will ensure the value entered is valid email id
