dynamic text area limit

Copy linkTweet thisAlerts:
Aug 11.2007

Hey I’m building a CMS for my church’s site and on the CMS I have a text area box that uses javascript to limit the amount of characters that can be typed into it. Here’s the [URL=”http://cms.ccgulfbreeze.com/”]CMS[/URL], it’s in the development stage right now. You’ll notice at the top that you can choose which topic you want to update, my question is this…How can I make it so that if the person updating the website chooses Topic Three to update it will change the text area limit to 210 instead of 1000?

try an finish it...you're on the right track...I think...


function limitAmount() {

if(document.webForm.id[3].selected){

var limit = "210"

}

else

{

var limit = "1000"

}

}

you can start by calling the function you wrote (limitAmount) on change...

i.e.
[code=html]<select onChange="limitAmount()">
<option value="">topic...</option>

<option value="1">1</option>
<option value="2">2</option>
<option value="3">3</option>

</select>[/code]
...

and make your var limit gets used somehow...

try and you shall learn ? ?
