Compare values inside delimited strings

Topic:

I need to write a Javascript function which accepts two comma separated values

(function() {	m2.getStatus = function(folderObjIDs, docObjIDs) {	};})();

Select All Code

Now both these parameters could have multiple values each separated with a comma.

Example, folderObjIDs could have 'a,b,c' and docObjIDs could have 'c,d,e'.

I need to check which value is common in both the parameters, and then alert it to the user ('c' in the example above).

Can someone please let me know how this can be done?

Thank you

500 points EXCELLENT

Uncaught TypeError: Object [object Array] has no method 'split'

that mean you don't pass << two comma separated values >>

	m2.getStatus = function(folderObjIDs, docObjIDs) {var f1 = "";var f2 = "";                if(typeof folderObjIDs!="string") {                   alert("folderObjIDs is not string, hope it's an array...");                   f1 = folderObjIDs                }                else {                  f1 = folderObjIDs.split(",");                }                if(typeof docObjIDs!="string") {                   alert("docObjIDs is not a string, hope it's an array...");  		   f2 = docObjIDs;                }		else {		  f2 = docObjIDs.split(",");                }        var f3 = [];        for(var i=0;i<f1.length;i++)            for(var j=0;j<f2.length;j++)                if(f1[i]==f2[j]) f3.push(f1[i]);        return f3.join(",");	};

Try to use split() function in javascript and its syntax from www.w3schools.com

folderObjIDs ='a,b,c';
array=folderObjIDS.split(",");

alert(array[0]); //// that you can get "a"

so next step will be easier for you for any operation for those two string comparsion
by your javascript function
