Question

JQuery - Form Action

Asked by: hb69

I have a form in an asp.net page (using .Net 3.5, C#, and JQuery 1.3).  I have failed to figure out how to get the form action="gotoawebpage" to function.  If I use a straight-up old school HTML form with old school javascript when I hit "submit" the form goes to the place defined in the ACTION definition.  But, when I place the form into the .net page using JQuery, I cannot get the form to go to another page, but it submits to itself only.

Ideas ???  I've attached my errant code below.  Thanks in advance.

HTML:
  <form name="myForm" action="anypage.htm">
    <div>
      First Name:<br />
      <input id="firstname" name="firstname" type="text" /><br />
      <input type="submit" />
    </div>
  </form>
 
The Javascript:
$(document).ready(function(){
       
    var form=$('#myForm'); // <-- prob not necessary
 
    $("form").submit(function() {
      if ($("input:#firstname").val() == "correct") {
        //$("span").text("Validated...").show();
        
        // we SHOULD just be forwarded to the form.action page but ... not happening.
        return true;
      }
      $("span").text("Not valid! firstname=" + $("input:#firstname").val()).show().fadeOut(1000);
      return false;
    });
 
});

First glance - on line 15 above, you've got " " quotes around form.  I think you probably want to remove those and use the variable you've declared, as that'll target the specific form.  In addition, #myForm references a form by ID, and you have only declared the name attribute on your form, not the ID attribute.  Also, I would probably reverse your logic so that you check if firstname is not equal to correct.

HTML:
  <form id="myForm" action="anypage.htm">
    <div>
      First Name:<br />
      <input id="firstname" name="firstname" type="text" /><br />
      <input type="submit" />
    </div>
  </form>
 
The Javascript:
$(document).ready(function(){
  var form=$('#myForm'); // <-- prob not necessary
  $(form).submit(function() {
    if ($("input:#firstname").val() != "correct") {
      $("span").text("Not valid! firstname=" + $("input:#firstname").val()).show().fadeOut(1000);
      return false;
    }
  });
});

That's a copy and paste of the jQuery demo right?  It works fine here.
Note: $("form") will grab all forms on the page.

What browser/OS are you testing this on?

<html>
<head>
<script src="http://code.jquery.com/jquery.js"></script>
<script>
$(document).ready(function(){
       
    var form=$('#myForm'); // <-- prob not necessary
 
    $("form").submit(function() {
      if ($("input:#firstname").val() == "correct") {
        //$("span").text("Validated...").show();
        
        // we SHOULD just be forwarded to the form.action page but ... not happening.
        return true;
      }
      $("span").text("Not valid! firstname=" + $("input:#firstname").val()).show().fadeOut(1000);
      return false;
    });
 
});
</script>
</head>
<body>
  <form name="myForm" action="anypage.htm">
    <div>
      First Name:<br />
      <input id="firstname" name="firstname" type="text" /><br />
      <input type="submit" />
    </div>
  </form>
</body>
</html>

Yeah, I can grab the values out of the form ... no problem there.  The problem is that when the form is submitted, it doesn't redirect / submit to the specified page.

In my sample (which was correctly identified as being ripped straight from the JQuery Documentation) I have form action="anypage.htm".  The "action" means that it is supposed to go to "anypage.htm".  This is what it doesn't do.

Problem exists in all broswers so it's not a browser issue, but a stupidity issue on my part. If I remove JQuery from the page, the "action" works and we go to "anypage.htm".  I put the JQuery references back in and the "action" does not function.

All comments appreciated.

 

by: hb69Posted on 2009-01-21 at 09:22:34ID: 23431730

Also, the form won't redirect even if I try to force it by using window.location="somepage.aspx";   I did some more googling for "JQuery Form Redirect" and have found others having the same issue, but have yet to see a solution.

Again, all help appreciated.

I got this working in FF3 / IE.

$(document).ready(function(){
  $("form").submit(function() {
    if ( $("input:#firstname").val() != "correct" )
    {
      $("span").text("Not valid! firstname=" + $("input:#firstname").val()).show().fadeOut(1000);
      return false;
    }
  });
});

Please post a demo site or your full source.

window.location="somepage.aspx" should work under all circumstances, and is entirely unrelated to jQuery.  There is most likely a problem with the code you have.

I have tested the code I posted verbatim with no problems (submits to anypage.htm) under most major browsers.
Try copy and pasting the code I posted and see if it still misbehaves.

 

by: hb69Posted on 2009-01-22 at 07:07:48ID: 23439915

I did try your code, both in it's complete state and in parts.  It works as expected.  In it's complete state it does redirect, it I take just the script and form portions it does not.  You are probably correct that it is something else in the page and as nothing else has come to light I'm going to give you full solution credit.  All I wanted was a push in the right direction and I think you helped me do that.

I can't post a demo site, unfortunately.  I work in a highly structured environment and I'd have to have an approval chain along with dog and pony shows in order to put it anywhere where it might be publicly viewable.   So, I'm going to look at the master page, the dependencies, inheritance, object model ... who knows if maybe our URL rewriter is the culprit.   Help always appreciated; never expected.

Much thanks ... I appreciate the code sample you threw together.

The solution (I think) lies outside of JQuery and therfore beyond the pale of the forum's assigned topic.  Again, much appreciation for the help.
