Question

IE6 and javascript void()

Asked by: pmmms

I have an ajax autocomplete that works fine on Firefox, Safari, IE7 but turns me crazy on IE6 and that's the browser the client use!

The problem is that I use a form header
<form name="theForm" id="theForm" action="javascript:void(0);">

When clicking on the submit button IE6 does nothing ie not the redirection.

I have tried "javascript:;"
"javascript: return halse;" gives an error in FF

Please help.

have you tried using "#" as the action?

 

by: Tomarse111Posted on 2009-03-05 at 08:26:43ID: 23807175

I tried "#" it doesn't work.

<form name="theForm" id="theForm" action="" onsubmit="return false;"> doesn't work in IE6

I'm not entirely sure what it is you want to accomplish. You mentioned that IE6 does nothing when action="javascript: void(0)". That's to be expected. You also mentioned something about IE6 not redirecting, but I'm confused as to what you want it to redirect to (you explicitly told it to not do anything). Can you elaborate on what exactly you want?

 

by: pmmmsPosted on 2009-03-05 at 11:49:56ID: 23809718

Here it is http://www.schaerbeek-proprete.be/fr/dvd_comd.html

In fact I have 2 scripts: one script validates the fields if on submit if it's OK it redirects or it diplays error msgs. Works fine on any browser.
The 2nd script is an ajax script that autocompletes a field via an external php file. Works fine on any browser.
Problem comes when I use the 2 scripts together: in IE6 the call for redirection is done (I can see it in debugbar) but the page is not displayed.
You can check at the url

Thank you

I'm looking things over. dvd_options.php is throwing the following error:

Undefined variable: liste on line 53

I doubt that's causing any of the problem, but the autocomplete isn't working because of it.

 

by: pmmmsPosted on 2009-03-05 at 12:37:24ID: 23810307

I have initialized the variable but the problem remains.

 

by: jwmcpeakPosted on 2009-03-05 at 12:45:46ID: 23810411

In submitForm(), return false instead of just returning. A form's default behavior is to perform the action specified in the action property. You have to explicitly tell the form not to behave normally by returning false.

You can also remove javascript:location.reload(false); from the form's action property.

You should also change the onSubmit method of the Validation reference type to return false if validation fails.

 

by: pmmmsPosted on 2009-03-05 at 15:03:42ID: 23812101

I have done that (the reload was left from a previous test) but it still not work.

What's strange is that the request is sent but not executed.

 

by: jwmcpeakPosted on 2009-03-06 at 06:00:38ID: 23816518

I get an error in IE5: _submitButton is null or not an object in line 540. It looks like the error is caused by initiating the auto complete in the load event. The code is part one below. No element exists with an id of bouton_submit. So part one should be changed to part two.

You also don't need to call submit() in the button's click event. That'll happen naturally when the user clicks the submit button.

Validation.prototype.onSubmit still does not return false if the validation fails. So if validation fails, the form is still reloads the page when the user clicks the submit button.

// part one
window.onload = function(){initAutoComplete(document.getElementById('theForm'),
 document.getElementById('street'), document.getElementById('bouton_submit'))};
 
// bouton_submit doesn't exist; _send is the submit button
// so part one should be changed to the code below
 
// part two
window.onload = 
function(){initAutoComplete(document.getElementById('theForm'),
 document.getElementById('street'), document.getElementById('_send'))};

Oops. I get an error in IE6, I mean.

 

by: pmmmsPosted on 2009-03-06 at 06:23:22ID: 23816737

I have done that, I also tried with the id of the submit button as "submit-button" to no avail.

I think the problem really is with the "javascript: void(0);"

Drives me mad

 

by: jwmcpeakPosted on 2009-03-06 at 07:25:37ID: 23817421

Alrighty. I saved the HTML and associated files to play with locally. Change the form start tag to the code below.

The javascript: void(0) is part of the problem, and it seems Prototype is another part of the problem.

I kept all the changes made in the previous posts the same; changing the form tag made it work in IE6, IE7, Firefox, Safari, Opera, and Chrome.

For what it's worth, action="javascript: void(0)" isn't the recommended solution to keep form from submitting; onsubmit="return false;" is.

<form name="theForm" id="theForm" action="" style="margin-left: 0px; margin-top: 5px;" onsubmit="return false;">

I now have a problem with the autocomplete.

Thank you very much for your help but I have decided to stop bothering you and use another "autocomplete" script.
Seems to work, just have to fight with the css but that's not real problem.

If you come in Brussels, let me know, I'll buy you a coffee or a beer.
