Hi
i was wondering if there is a quick way to search for a item within an
array. Here is my approach for this functionality. It's an prototype
for an Array method called "has":
Array.prototype.has = function(needle) {
for (var i=0;i<this.length;i++) {
if(this[i] == needle){ return true; }
}
return false;
}
var someArray = ['jim', 'marge', 'timmeh', 'bob'];
if( someArray.has('bob') )
{
alert('found bob')
}
Isn't there something like "has()" in prototype already? I have seen
the find / findAll, but the example in the docs are kinda complex for
"just that".. could someone break it down for me please? i would much
appreciate.
TIA, Kjell
