ASP Checkbox and on click

Hi,
I am a newbie developing a form which has a number of checkbox and have 3 main category,
Approve all, Reject all, Query.

My main problem is that once I click any of these 3 then the other two should be unchecked and all elements under there should be checked. If you remove a check for any bottom element then the All element is removed.

I have attached a simple pic of the form. I would be grateful if someone could tell me the code in asp for the above form sample along with any javascript!

Many thanks in advance!

 

I believe you will have to set the 'value' property of each checkbox to false.

Ex.

Code:

private sub [COLOR="Red"]TEXT1_APPROVE[/COLOR]_OnClick ()
     [COLOR="Red"]TEXT1_REJECT[/COLOR].Value = false
     [COLOR="Red"]TEXT1_QUERY[/COLOR].Value = false
end sub

Where everything highlighted in red is the actual name of your checkboxes.

edit: Just read Kodo's response in your other thread...am I leading you down the wrong path here?

 

Well most browsers dont support vbscript specially thoese commands for onclick. So I would be more inclined to a javascript solution. I tried to create a similar javascript but then when the button is clicked i start getting errors on page!

Any help please?

 

I don't have much time so it'll be breif.

To check the status of a checkbox, you must use the DOM.

Code:

document.getElementById("approved1").value

Will return the state of the checkbox with the ID approved1, as such...

Code:

<input type="checkbox" id="approved1" />

A more complete example.

Code:

<script>

function checkInput() {
if (document.getElementById("approved1").value) {
    alert('The item is checked')
} else {
     alert('The item is NOT checked');
}
}
</script>
 
....

<input type="checkbox" id="approved1" />
<input type="button" value="Submit" onclick="checkInput()" />

 

additionally , Approve all, Reject all, and Query all should be radio buttons with the same name and id

<input type="radio" name="radMainOptions" id="radMainOptions" value="Approve All" />
...
...

That will place the radio buttons in the same logical group so when you can only have one selected at any given time.

 

Thanks for the above. However, I was wondering if there was any dynamic way of doing the same> Eg as soon as i click on approveall the rario / checkbox below gets highlighted, without clicking the submit!

 

Done Thanks for all your help!
