    Validation function problem.

    I've a function that validate a form field:

    <html>
    <head>
    <script language="JavaS cript">
    function CheckFields(For mSubmit,BtnName )
    {
    if (BtnName!="Canc el")
    {
    check = true;
    if (FormSubmit.Use r_Account.value == ""){
    alert ("Username compulsory");
    FormSubmit.User _Account.focus( );
    return false;
    }....

    My FORM:
    <form action="<?php echo $editFormAction ; ?>" name="formSubmi t"
    method="POST"> <!--form action myself-->
    ....
    <input type="submit" name="SubmitBut ton" value="Add"
    onClick="CheckF ields(this.form , this.value)">
    &nbsp;<input type="submit" name="SubmitBut ton" value="Cancel">

    Now, if I click on cancel, I do redirect (with PHP) to a previous page. If I
    click on Add, a check is done on the compulsory fields. I would like the
    focus on the selected field (the one that isn't right), but the form is
    reloaded. How to avoid this ?

    I've tried to put the check on the form.OnSubmit (that fires before I submit
    the form, and set the buttons input type as "button" instead of "submit"),
    instead of the button click (that does submit the form), but I can't
    retrieve with button was pushed. (I've tried FormSubmit.Subm itButton.name,
    but it doesn't work)

    Please help.

      Your event handler needs to *return* the value from CheckFields:
      onClick="return Checkfields..."

              in case you have a lot of forms to implement
              and a lot of rules to follow or fields to validate
              you shoudl check out PEAR:HTML_Quick Form.

              it also supports client-side validation via
              auto-generated or customly written javascript
              functions.
