You can find out "? exist or not by RegExp pattern, take a look the follow code for reference only, and seach the position as the last post mentioned

btw I edited my initial answer, so please refresh in browser to see the suggested solution,
it's:
var str = "welcome?page#isexperts";
var n = str.search("\?");
n contains the position of your searched character in the string (accounted for the fact that first character has index=0)
it's:
var str = "welcome?page#isexperts";
var n = str.search("\?");
n contains the position of your searched character in the string (accounted for the fact that first character has index=0)
