Nov 3, 2011I'm writing a piece of JS code that returns a result of true if the pattern appears in string as a substring (case sensitive) but would like to extend its functionality to returns true if all the individual characters of pattern appear in string (regardless of order).
For example:This is what the program currently does:
match1("adipisci","pis") returns true
Whereas I would now like it to do this:
match1("adipisci","sciip") returns true
match2("adipisci","sciipx") returns false because x does not exist in variable
match3["adipisci","adipisci"] returns true in array 1 and 2 if "sciip" is searched
match4["adipisci","adipiscix"] returns false in array 1 and true in array 2 if "sciipx" is searched
I am having difficulty implementing this into my code... this is what I've done so far:

Convert A Number To A String?
Apr 3, 2010I'm trying to write code to swap images in a list. It's going to be a star rating control that highlights stars as you hover over a star. each image in the list has an onmouseover="highlight(this)" function and a unique id of 1 - 10.
Code:
function highlight(star) {
var num = Number(star.id);
for (i = 0; i < num; i++)
[Code].....
I'm trying to convert the number 'i' used by the for loop to a string so it can be used by the getElementById() method to select the stars to be highlighted. But my intellisense is telling me there is a problem with that line. I tried
var id = String(i+1);
but this didn't work either.
what have I gotten wrong?
