array_search() in Javascript?

[hsriat]

Is there any function in JS similar to array_search() of PHP which returns the key that contains the particular value, passed as argument. Or I need to make it myself?

Well, I guess there's not!

function arraySearch(arr,val) {
	for (var i=0; i<arr.length; i++)
	if (arr[i] == val)
	return i;
	return false;
}

If you want PHP equivalent functions, see this link. Your code is similar (though could do with some proper indentation).
