[RESOLVED] noob javascript problem

Copy linkTweet thisAlerts:
Oct 29.2008

Hi everyone
I just started to learn Javascript and i am running into a problem i just cant figure out how to fix. Just to set up the situation i have a combo box with different options in it and i created a button to remove an option if i desire. When the button is pressed 2 options are removed and it is never the selected option…. if any of you pros can spare a min to look at this i would greatly appreciate it. Thanks in advance Chris Osburn

[CODE]
function RemoveListItem(RemoveItemName){
var oListOutPut = document.getElementById(‘ListOutPut’);
var intListLength = oListOutPut.options.length;
for (var i=0; i <= intListLength; i++){
if (oListOutPut.options[i].value = RemoveItemName){
oListOutPut.options[i] = null;

}
}
}
[/CODE]

@ZeroKilledOct 29.2008 — try this code:
<i>
</i>function removeOption(){
var oListOutPut = document.getElementById('ListOutPut');
oListOutPut.remove(oListOutPut.selectedIndex);
}

@ZeroKilledOct 29.2008 — sorry for not explaining a bit about your code. at a glance, in the line [b]if (oListOutPut.options[i].value = RemoveItemName){[/b] what you really doing is assigning a value to the property [b]value[/b] instead of camparing the option's value with the variable. so, you have to use the comparison ==

Success!
