I've lokked high and low for a script to sort this out...

Basically I need a function that can be called upon by clicking a check box. The function should copy the current value of a drop down menu and transfer it into a checkbox... Does that make sense?

I've already used a function to transfer values from textbox to text box.

function copy() {

document.form1.CC_Address.value = document.form1.Address.value ;

}

However I can't manage to make this work for dropdown menus to text box.

Anyone???

<script language="javascript" type="text/javascript">
function fillcheckbox(selection)
{
document.form1.mycheckbox.value = selection.value;
}
</script>

<select name="combo" onchange="fillcheckbox(this);">
.....
</select>
<input type="checkbox" name="mycheckbox" value="zero">

....


Remember that the value of the checkbox will only be passed to the form's action page when the checkbox is selected.

Not quite. I wanted the value from the dropdown to be passed to a text box...

e.g.

function doThis() {
if (document.forms.myform.mycheckbox.checked == true) {
document.forms.myform.mytextfield.value = document.forms.myform.myselection.value;
}
}

…

<select id="myselection" onchange="doThis()">
…
</select>

Change id and function names to suit.

You want the value from the drop down passed onto to a textbox when you click on a checkbox?

Well in you fist post you said that you want a value from a combobox passed on to a checkbox...

which one is it?

this is the intended form.

function populateTextBoxes()
{
document.form1.mytextbox.value = document.form1.combobox.value;
}

and call this inside the checkbox input tag - with an onchange event.

You might wanna add checker so that the function is only triggered when the checkbox is actually checked.
e.g.

function populateTextBoxes() {
	if (document.forms.form1.checkbox.checked == true) {
	document.form1.mytextbox.value = document.form1.combobox.value;
	}
}

It's also an idea to add in some else code that clears the second set of input fields if the checkbox is then unchecked.

This didn't work in the end...

document.form1.mytextbox.value = document.form1.combobox.value;

No error messages show up but value is passed.

My chance I tried

document.form1.mytextbox.value = document.form1.combobox.selected;

and it worked.

Cheers for the help anyway.

I'm completly wrong.

My changes didn't actually work.

The script given by you worked after all. Wrong side of the bed of something!!!

All's well…

combobox.value

is not supported cross-browser afaik, you should get the value of the currently selected option instead, using

combobox.options[combobox.selectedIndex].value

instead, remembering to check that combobox.selectedIndex is > -1 first, otherwise no option is selected.

HTH,
