Javascript: Exploding a string into an array
Found the function below at webreference. It will take a string and explode it into an array.
In my project, I had one field in a form where the user would enter several email addresses seperated by semi-colon’s. I wanted to validate that each email address was valid, but first you have to seperate the long string…
function explodeArray(item,delimiter) {
tempArray=new Array(1);
var Count=0;
var tempString=new String(item);
while (tempString.indexOf(delimiter)>0) {
tempArray[Count]=tempString.substr(0,tempString.indexOf(delimiter));
tempString=tempString.substr(tempString.indexOf(delimiter)+1,tempString.length-tempString.indexOf(delimiter)+1);
Count=Count+1
}
tempArray[Count]=tempString;
return tempArray;
}

wow, not only are you adding tempArray inside that function to the global namespace, but that function is just horrible…
IE and Moz support the split method.
var tokens = str.split(delim);
if your javascript implementation doesn’t support split on strings, add it:
String.prototype.split = function(delim)
{
// your split code here. (hopefully using RegExp)
};
now all your strings will have this capability.
