需要帮助在 kendoGrid 中按天数对这些 json 结果进行排序。 我需要一种方法将加号转换为 .5 或类似的东西。 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放回去？
{ name: Alex, days: "2" },
{ name: Jason, days: "1" },
{ name: Fred, days: "2+" },
{ name: Jane, days: "3" },
{ name: John, days: "3+" }
这是我开始工作的代码
<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" }

];
