如果有人想要使用更集成的方法jquery /questions/tagged/jquery:
(function($){
$.extend({
// Case insensative $.inArray (http://api.jquery.com/jquery.inarray/)
// $.inArrayIn(value, array [, fromIndex])
// value (type: String)
// The value to search for
// array (type: Array)
// An array through which to search.
// fromIndex (type: Number)
// The index of the array at which to begin the search.
// The default is 0, which will search the whole array.
inArrayIn: function(elem, arr, i){
// not looking for a string anyways, use default method
if (typeof elem !== 'string'){
return $.inArray.apply(this, arguments);
}
// confirm array is populated
if (arr){
var len = arr.length;
i = i ? (i < 0 ? Math.max(0, len + i) : i) : 0;
elem = elem.toLowerCase();
for (; i < len; i++){
if (i in arr && arr[i].toLowerCase() == elem){
return i;
}
}
}
// stick with inArray/indexOf and return -1 on no match
return -1;
}
});
})(jQuery);
