checkboxes and javascript

[jenboland]

First, I am not a programmer, just a hack who tries to make things work

I am trying to process a form using javascript that detects if the user has checked the set as default box and then sets a cookie based on the regional preference. I figured out how to get the values from the radiobuttons, but am stuck on the checkbox value. Here's my form code. Like I said, I just need to know how to retreive the value from the checkbox field.

<form name="form">
<p><b>Select Region</b><br>
<input type="radio" name="group1" value="North America" checked>
North America<br>
<input type="radio" name="group1" value="Europe">
Europe</p>
<p>
<input name="remember" type="checkbox" id="remember" value="yes">
Remember selection<br>
<input type="Button" onClick="MM_callJS('GetDefault')" value="Select">
</p>
</form>

Hi, I don't make a living off of JavaScript, but I think I know the answer to your problem.

First, create an IF statement to check your checkBox. Example like so:

if (docuemnt.formNameHere.remember.checked)
{
---do some code here---
}
else
--- do something else here---


Then, since you want to retrieve the checkBox value, assuming it's a 'true' or 'false', you can create a variable to do so in your IF statement like:

if (...)
{
isChecked.value = 'true';
}
else
isChecked.value = 'false';

I hope that works for you.

<input name="remember" type="checkbox" id="remember" value="yes">
Remember selection<br>

</p>
</form>

You shouldn't use "form" for the name of your form to avoid confusion. Also, instead of value="yes", use "checked" instead on its own as follows:

<input name="remember" type="checkbox" id="remember" checked>

So assuming you've named your form "theForm", you can retrieve the checkbox value as follows:

var cBoxVal = document.theForm.remember.checked;

cBoxVal will be 'true' or 'false' depending on whether the checkbox has been checked.

Hope that helps.

If you ever want to pass the W3C XHTML check, you declare your statement as

<input name="remember" type="checkbox" id="remember" checked="checked" />
