Question

需要帮助在kendoGrid中按日排序这些json结果。我需要一种方法将加号转换成.5或其他类似的东西。我想我必须遍历每一个，如果我找到加号，然后将值更改为number.5然后在显示之前将新值重新放入？

{ name: Alex, days: "2" },
{ name: Jason, days: "1" },
{ name: Fred, days: "2+" },
{ name: Jane, days: "3" },
{ name: John, days: "3+" }

这是我工作的代码

<body>
    <div id="grid">

    </div>
    <div>
        <script>
            $(document).ready(function () {
                //JSON data 
                var people = [
                { firstName: "Hasibul", lastName: "Haque", email: "hasibul2363@gmail.com", rank:"2" }
                , { firstName: "Jane", lastName: "Smith", email: "jane.smith@kendoui.com", rank: "3+" }
                , { firstName: "Jason", lastName: "Doe", email: "hasibul2363@gmail.com", rank: "1" }
                , { firstName: "John", lastName: "doe", email: "hasibul2363@gmail.com", rank: "3+" }
                , { firstName: "Joan", lastName: "doe", email: "hasibul2363@gmail.com", rank: "5" }
                , { firstName: "Jack", lastName: "doe", email: "hasibul2363@gmail.com", rank: "3" }
                 , { firstName: "Jacob", lastName: "doe", email: "hasibul2363@gmail.com", rank: "3-" }
                  , { firstName: "Joe", lastName: "doe", email: "hasibul2363@gmail.com", rank: "3-" }

                ];


                $('#grid').kendoGrid({
