Question

i am using HTML5 and indexOf gives me an error, so what else can i use to search for the word “correct” in a string: a001_new_quiz_multiple_choice_new_mc4_correct.html which is in a variable called value1

function SetAPIValue(key1, value1)
{
   // alert("action is " + key1 + " and data is " + value1);
   console.log(value1);

   var str = "wrong";
   var n = str.search(value1);
   if (n > 0)
     alert("found");
}

the error i get: 0x800a01b6 – Microsoft JScript runtime error: Object doesn’t support property or method ‘indexOf’

I don’t know how you used indexOf, but this works :

var value1 = "a001_new_quiz_multiple_choice_new_mc4_correct.html";
var n = value1.indexOf("correct");
if (n >= 0) alert("found");   

Maybe you tried "correct".indexOf(value1); instead of value1.indexOf("correct"); ?
