Form submit problem using JavaScript in Internet Explorer 6

I have just done the code for submit the form using JavaScript.

It works in all browsers except in Internet Explorer 6.

I have pasted my HTML form and JavaScript code below.

Can you please find what's the problem with it?

JavaScript:

    <s开发者_如何学Pythoncript type="text/javascript" language="javascript">
    function dodelete(image_id)
    {
        if (confirm("Are you sure want to delete this image?"))
        {
            document.getElementById('image_id').value=image_id;
            document.del_form.submit();
        }
    }
    </script>

HTML Code:

    <form name="del_form" id="del_form" method="post">
        <input type="hidden" name="do" id="do" value="delete" />
        <input type="hidden" name="image_id" id="image_id" />
    </form>

Function Call Code:::

<p class="video">
  <a href="javascript:void(0)" onclick="dodelete('<?php echo $row['image_id']?>')">                                 
    <img src="<?php echo $cfg->admin_image_path; ?>/delete_icon1.gif" border="0" alt="Delete"/>
   </a>
</p>

What is returned by:

document.getElementById('image_id')

It returns one INPUT element of collection of elements?

Try to replace:

document.getElementById('image_id').value=image_id;

with:

document.del_form.image_id.value=image_id;

OnSubmit call for javascript would help.

<form name="del_form" id="del_form" onsubmit="dodelete(value);" >
    <input type="hidden" name="do" id="do" value="delete" />
    <input type="hidden" name="image_id" id="image_id" />
</form>

There are two things I'd like to try, I'm not sure why or when this doesn't work it seems random, first try to set a timeout for the submit :

document.doSubmit = function() {
    document.del_form.submit();
}
setTimeout("document.doSubmit();", 100);

Sometimes, just return something after the click works :

<input type="hidden" name="image_id" id="image_id" onclick="submitFormFunction(); return false;” />

What happens if you replace:

    document.del_form.submit();

with:

document.getElementById('del_form').submit()

---

Try to move method='POST' to the beginning of form element definition.

I mean -- method attribute should be the first attribute of form element.

If I remember well, this fixed some problems with submitting forms on IE6.

I have edited your code a little bit.

<script type="text/javascript" language="javascript"> 
    function dodelete(image_id) 
    { 

        if (confirm("Are you sure want to delete this image?")) 
        { 

            document.getElementById('image_id').value=image_id; 
            document.del_form.submit(); 
        } 
 return false;
    } 
</script> 

and the HTML with some test Image ID and it works in IE6

<form name="del_form" id="del_form" method="post" onSubmit="return(dodelete('2'));"> 
        <input name="do" id="do" value="delete" /> 
        <input name="image_id" id="image_id"  /> 
<input type="submit" value="Submit">
</form>

Let's try again :).

What happen after replacing:

onclick="dodelete('<?php echo $row['image_id']?>')">

with:

onclick="dodelete('<?php echo $row['image_id']?>'); return false;">

What exactly doesn't work with your code? Throw JS error, there is no server request, values in request are empty?

And (maybe the most important question) -- where is action attribute for your del_form form?

---

replace

<a href="javascript:void(0)"

with

<a href="#"

IE have problem with that for the dom that fires the JS submit.
