Question

I am able to search a string using str.search("me"); and str.search("=");

But when i serach for str.search("?");

I get the error Unexpected Quantifier.

Why is that?
How can i search for "?" using something other than a regular expression?

Answer 1

alert(str.indexOf("?")); // returns position as integer if present, -1 otherwise

Typical usage scenario is:

if(str.indexOf("?") !== -1) {
    // present
}
