Question

I’m looking for a way to verify against an array.
I’m lost in the array searching part.

I may get an array like this:

stream = ["apple","orange", "grape", "peach","strawberry","watermelon", "kiwi", "raspberry"];

But I only want :

selection = ["apple", "peach","strawberry","kiwi", "raspberry"];

How would I write a statement that would say:
If something in this stream matches my selection, do something.

You must use the inArray command like this:

if($.inArray(ValueToCheck, YourArray) > -1) { alert("Value exists"); }

InArray will search your array for the value you asked for and return its index. If the value isn’t present, it returns -1.
