I have upgraded to jQuery 1.10.2 in my application, and I am getting an error in my code (in $.each).

'invalid 'in' operand e' .

This error occured after upgrading jQuery. In 'this._currentFilterbarValue', there is a string value which I need to check against some condition.

_CheckForSkipInput: function () {
    var IsSkip = false;
    if (this._currentFilterColumn.type == "String") {
        var stringSkipInput = new Array(">", "<", "=", "!");
        $.each(this._currentFilterbarValue, function (index, value) {
            if (jQuery.inArray(value, stringSkipInput) != -1)
                IsSkip = true;
        });
    }
    return IsSkip;
},

What you are trying is to iterate through the characters in this._currentFilterbarValue(which is a string) and therefore jQuery.each() is failing

The $.each() function can be used to iterate over any collection, whether it is an object or an array.

So try like

 var IsSkip = false;
 if (this._currentFilterColumn.type == "String") {
     var stringSkipInput = new Array(">", "<", "=", "!");
     for (var i = 0; i < s.length; i++) {
         if (jQuery.inArray(s[i], stringSkipInput) != -1) IsSkip = true;
     }
 }
 return IsSkip;
 },

Another approach,

Converting your string this._currentFilterColumn to character array and then iterating using $.each()

var arr = this._currentFilterColumn.split("");  //Converting a string to char array
$.each(arr, function (index, value) {  //Now iterate the character array
  if (jQuery.inArray(value, stringSkipInput) != -1) IsSkip = true;
});
