JavaScript - Javascript Variable To Form Hidden Variable's Value

I really thought this would work, a user goes to a page, selects a value from a select box then clicks a link to run a report using that hidden variable as a parameter. I am attempting to place the value in the URL to pass it. I'm sure the javascript is working, and maybe it's the HTML I've messed up - not sure.
Here is the javascript (the alert does return the correct value):
Code:

function OnChangeDay() {
	//assign the day id to the hidden variable $day
	x=eval(document.getElementById("day_loc_id_select").value)
	
	if(x) {	
        document.getElementById("test_day_id").value=x;
    } else {
        document.getElementById("test_day_id").value=0;
    }
	// test
	alert(document.getElementById("test_day_id").value)  
}

Here is the calling HTML:
Code:

<input type="hidden" name="test_day" id="test_day_id" value="">

 <select name="day_loc_id" id="day_loc_id_select"  
              onchange="OnChangeDay()"> 
 <option></option>
        <?= form_options($day_loc_options) ?>
</select>

And here is the HTML that should send the value, but I get day= (nothing)
Code:

<a href='/depts/edoptions/excel_extract.php?ex=2&day=<? echo $test_day ?>'>SLIP Data to Excel</a>

Can anyone point out where I've messed up?
Thanks

Hi,
I wanted to know if there is way in Javascript to send a hidden variable to an external URL without actually submitting to the URL?

Code below is what I intend to do. I want to use an image to do an onClick event and send the name to an external URL without actually doing a submit. Code:

 <td width="25">&nbsp;</td>

		  	<input type="image" src="images/btn_Activate.gif" onClick="window.location.href='www.abc.com'">
		  	<input type="hidden" name="name" value="<% = name %>">

		  </td>

Thanks.
Jeeten.

Hi all,

I'm having some trouble with the this...

I have a PHP based calendar where the cells will change color depending on the number of clicks.. this all works fine, but is pointless if I can't send the outcome along in an email. I can do this with PHP but first need to get the values into a hidden field.

This is what I have:

Code:

<script type="text/javascript">	
	function countClicks (obj){
            if (!obj.count) {
                obj.count = 0;
            }
 
            obj.count++;
            if (obj.count > 4) {obj.count = 1};
 
            if(obj.count == 1){
                obj.style.color='#FFFFFF';
                obj.style.backgroundColor='#66CC33';
                obj.parentNode.style.backgroundColor='#66CC33';
				document.getElementById("availability").value='Available';
            }
           
            if (obj.count == 2){
                obj.style.color='#FFFFFF';
                obj.style.backgroundColor='#FF0000';
                obj.parentNode.style.backgroundColor='#FF0000';
				document.getElementById("availability").value='Not Available';
            }
           
            if (obj.count == 3){
                obj.style.color='#FFFFFF';
                obj.style.backgroundColor='#FFCC33';
                obj.parentNode.style.backgroundColor='#FFCC33';
				document.getElementById("availability").value='Working';
            }
			
			if (obj.count == 4){
                obj.style.color='#000000';
                obj.style.backgroundColor='#FFFFFF';
                obj.parentNode.style.backgroundColor='#FFFFFF';
				document.getElementById("availability").value='Not Set';
            }
        }
</script>

and...

Code:

echo "<input type=\"hidden\" name=\"availability\" id=\"availability\" value=\"\">";

All I'm trying to do is populate value with either 'available', 'not available', 'working' or 'not set'...

however, it is worth noting that each cell may have a different value, e.g. 1 cell might be working while the other is not available... so i need to pass the values of all the cells.

Can anyone help me out here.

Many thanks,

Hello
I have a piece of javascrip that refreshes the page:

----------

Code:

<script type="text/javascript">
<!-- Begin


function reFresh() {
 location.reload(true)
}
/* Set the number below to the amount of delay, in milliseconds,
you want between page reloads: 1 minute = 60000 milliseconds.
2 minutes = 120000 milliseconds 5 minutes = 300000 milliseconds*/

window.setInterval("reFresh()",20000);
// End -->
</script>

--------


I am new to javascript and wanted to use an html options menu in order to be able to choose the refresh interval:
Code:

  

<SELECT NAME="refreshtime">
<OPTION VALUE="60000">1 min</option>

<OPTION VALUE="120000">2 min</option>

<OPTION VALUE="180000">3 min</option>

<OPTION VALUE="240000">4 min</option>

</SELECT>

I know that I have to pass a variable to the function. I have tried several variations but none have worked.

I have mostly received a "done with errors" warning.

Any help would be appreciated.
Thanks
