访问的Javascript变量后它被初始化ViewBag [英] Access to Javascript variable after it was initialized by ViewBag

问题描述

下面是动作功能：

public ActionResult TranslatorForm()
{
    string[] arrDepartment = new string[]{"Engeneering","Science","Mediciene"};

    ViewBag.Department = arrDepartment;
    return PartialView("TranslatorFormPartial");
}

下面是jQuery函数：

Here is JQuery function:

 $(document).ready(function () {
    var departments = "@ViewBag.Department";
 });

正如你可以看到我存储从服务器对数据传递的 ViewBag.Department 在JavaScript variable.At某些时候，我想创建下拉列表，并使用数据的部门变量它填充部门。

As you can see I store the passed data from the sever ViewBag.Department in departments javascript variable.At some point I want to create drop-down list and populate it using data in departments variable.

但我不如何访问的元素在部门javascript变量。
任何想法，我怎么能实现呢？

推荐答案

使用 ViewBag 属性分配给一个JavaScript数组

Assign the ViewBag property to a javascript array using

var departments = JSON.parse('@Html.Raw(Json.Encode(ViewBag.Department))');

然后就可以在普通的循环或使用jQuery的访问。每（）的功能，例如：

for (i = 0; i < departments.length; i++) { 
    var dept = departments[0]; // returns `Engeneering`
}
