JS，在数组中搜索不起作用

Question

 0. <script type="text/javascript">
 1.   var games = new GameList("bets");
 2.   games = games.getGames(); //an Array, example: games = ("1313_55", "3353_65");
 3.   
 4.   var game_ids = $.map(games, function(_g) {     
 5.     return _g.split('_')[0];
 6.   });
 7.   
 8.   idsList = game_ids.join(",");
 9.   var _srch = -1;
10.   for(var i = 0, j = idsList.length; i < j && _srch == -1; i++)
11.   {
12.     _srch = idsList.search(/ids[i]/i);
13.   }
14. </script>

line 12 doesnt work. any ideas? well line 12 works, but does not return the result correctly.

what i am trying to do: Example:

I am searching a name in string:

var str = "my name is VuRaL"; 
_srch = str.search(/VuRaL/i); 

//thats what i want to do.

str.search(/VuRaL/i); only VuRaL needs to be an array value like ids[1] etc.

Example: str.search(/ids[i]/i);

Thanks!

Answer 1

Um. Line 8 converts your array into a string. Line 10 has you iterating over this string on a character by character basis. Are you trying to find something in the overall string? You don't need your for(){} loop if so.

Answer 2

Is this what you're going for?

 _srch = idsList.search(new RegExp("ids[" + i + "]", 'i'));

In case you want to search for brackets themselves, you'll need to escape them like so:

_srch = idsList.search(new RegExp("ids\\[" + i + "\\]", 'i'));

Answer 3

/ids[i]/ is a regex literal. It's not actually inserting the value of the variable i . Also, [ and ] have special meaning in JavaScript regexes, so you need to escape them. Replace line 12 with this:

_srch = idsList.search(new RegExp('ids\\[' + i + '\\]', 'i'));
