Morning experts,

Bit of a Javascript question for you..

I have a drop down, that needs to action a specific javascript event when someone clicks on the one the "other" field.

It needs to show a div.

My current code is below. This works absoloutely fine in Firefox 3, however in IE it fails miserably and dosen't action the code.

What can I do?


<select name="event" class="formfield">
	<option selected disabled="disabled">Select your event type</option>
	<option value="1" onClick="javascript:animatedcollapse.hide('type')">Activity Day</option>
	<option value="2" onClick="javascript:animatedcollapse.hide('type')">Conference</option>
	<option value="3" onClick="javascript:animatedcollapse.hide('type')">Corperate Hospitality</option>
	<option value="4" onClick="javascript:animatedcollapse.hide('type')">Dinner</option>
	<option value="5" onClick="javascript:animatedcollapse.hide('type')">Exhibition</option>
	<option value="6" onClick="javascript:animatedcollapse.hide('type')">Gala Dinner</option>
	<option value="7" onClick="javascript:animatedcollapse.hide('type')">Interviews</option>
	<option value="8" onClick="javascript:animatedcollapse.hide('type')">Meeting</option>
	<option value="9" onClick="javascript:animatedcollapse.hide('type')">VIP Meeting</option>
	<option value="10" onClick="javascript:animatedcollapse.hide('type')">Party</option>
	<option value="11" onClick="javascript:animatedcollapse.hide('type')">Product launch</option>
	<option value="12" onClick="javascript:animatedcollapse.hide('type')">Team Building</option>
	<option value="13" onClick="javascript:animatedcollapse.hide('type')">Training Courses</option>
	<option value="14" onClick="javascript:animatedcollapse.toggle('type')">Other</option>
	</select>
 
<div id="type" name="type" style="display:none">
Specify: <input type="text" name="name9"/>
</div>

Hard to say without seeing the code for "animatedcollapse.toggle('type')"...

I would attach the onclick event to the <select>, then test the target within the event handler to determine the <option> element that was clicked. Much less typing ;-)

badotz, cheers for the reply, it's all about the copy and paste though.... animatedcollapse.toggle is a function from Dynamic drive's code..

http://www.dynamicdrive.com/dynamicindex17/animatedcollapse.htm

Is your link..

Just because I am a JS idiot, what would be the code for working out which form element has been selected and thus activating either the hide or toggle functions of animated collapse?

Cheers

Something along these lines (untested):


function sel_on_click(e) {
    e = e || window.event;
    
    var target = e.target || e.srcElement, // Element that caused the event to fire
        value,
        text;
    
    if (target.nodeType === TEXT_NODE) { // defeat Safari bug 
        target = target.parentNode; 
    }
    // [target] contains the <option> that was clicked
    value = target.value; // [1] through [14]
    text = target.text;   // [Activity Dat] through [Other]
}

Sorry to be a pain, but I think I am being an idiot..

Have created some code, but I think with my javascript I am thinking far too PHP..


<script type="text/javascript">
function sel_on_click(e) {
    e = e || window.event;
    
    var target = e.target || e.srcElement, // Element that caused the event to fire
        value,
        text;
    
    if (target.nodeType === TEXT_NODE) { // defeat Safari bug 
        target = target.parentNode; 
    }
    // [target] contains the <option> that was clicked
    value = target.value; // [1] through [14]
    text = target.text;   // [Activity Dat] through [Other]
	
	if(value == "14"){
		document.write("Yep, toggled type");
		animatedcollapse.toggle('type');
	} else {
		document.write("Hid type.");
		animatedcollapse.hide('type');
	}
		
}
</script>
</head>

Change:

document.write("Yep, toggled type");
...
...
document.write("Hid type.");

to:

alert('Yep, toggled type');
...
...
alert('Hid type');

Hi there,

Got it working but only by commenting out some of your code.

If I comment out the below code it works like a charm..

I don't know enough about JS to be able to debug it. Any ideas?
if (target.nodeType === TEXT_NODE) { // defeat Safari bug 
    target = target.parentNode; 
}

Ah, it's a missing constant value. Change:

if (target.nodeType === TEXT_NODE) { // defeat Safari bug

to:

if (target.nodeType === 3) { // defeat Safari bug

Sorry about that...
