Limit text area value and cut the rest
- by streetparade
I have a textarea which users can enter some tags.
I need to limit this tags to 20 tags.
Tags could be enterer this way
maytag1,mytag2,mytag3
What i wrote is this function
function limitTags()
{
var tags = $("input[type=text][name=tags]").val()
var tag = $.trim(tags);
var selected = new Array();
/**
* replace the last ','
*/
if(tag.substring(tag.length - 1) == ",")
{
*///tag = tag.replace(tag.length - 1, '');
}
var enteredTags = tag.split(",");
if( enteredTags.length > 20 )
{
//$("input[type=text][name=tags]").val(enteredTags.join(",", enteredTags));
alert("Only 20 Tags allowed");
}
}
The alert works just fine but, after the alert box is gone. i can continiue entering tags till the alert box appears.
What i need is cut the text after the messagebox which was entered also the last ","
I hope i could ask my question clear.
Thanks
