A summary of ComboBox multiple-selection incompatibility issues in jquery

  recently developed jquery in IE10, a summary of ComboBox in jquery, and interested friends can understand the following

Recently developed jquery in IE10, a summary of the incompatibility of ComboBox multiple selections in jquery.     When you set the property "Multiple:true" to ComboBox, IE10 cannot complete the multiple selections, and the error follows:  code as follows: function _7e8 (_7e9,_7ea) {  var _7eb=$ . Data (_7e9, "combobox");  var opts=_7eb.options;  var _7ec=$ (_7e9). Combo ("getValues");  var _7ed=_ 7ec.indexof (_7ea+ "")//10650 line here error   if (_7ed>=0) {  _7ec.splice (_7ed,1);  _7e7 (_7E9,_7EC);    The IndexOf method is not supported in F12, and there are now two solutions to this problem:    1. Modify source     To change the above code to   code as follows: <strong> function _7e8 (_7e9,_7ea) {  var _7eb=$.data (_7e9, "combobox");  var opts=_7eb.options;  var _7ec=$ (_7e9) . Combo ("getValues");  var _7ed = (function (arr,str) {  str = str + "";  for (Var i=0,l=arr.length;i<l;i++ {  if (arr[i] = = str) return i; }  return-1; }) (_7ec,_7ea);  if (_7ed >= 0) {//modified in 2013-6-25 19:04  _7ec.splice (_7ed,1);  _7e7 (_7E9,_7EC); }</strong>    2. Add IndexOf method   code as follows : <strong>iF (! ARRAY.PROTOTYPE.INDEXOF) {  Array.prototype.indexOf = function (target) {  for (Var i=0,l=this.length;i<l; i++) {  if (this[i] = = target) return i; }  return-1; }; }</strong>    Actually, I'm still pretty pushing. Recommend the first method, because more convenient, I was the first way to use.
