Passing strings with Single Qoute from MVC Razor to JavaScript
提问by user646306
This seems so simple it's embarrassing. However, the first question is when passing a value from the new ViewBag in MVC 3.0 (Razor) into a JavaScript block, is this the correct way to do it? And more importantly, where and how do you apply the proper string replacement code to prevent a single quote from becoming ' as in the resultant alert below?
这看起来很简单，很尴尬。但是，第一个问题是，将值从 MVC 3.0 (Razor) 中的新 ViewBag 传递到 JavaScript 块时，这是正确的方法吗？更重要的是，您在哪里以及如何应用正确的字符串替换代码来防止单引号变成 ' ，如下面的结果警报所示？
Adding this into a single script block:
将此添加到单个脚本块中：
alert('@ViewBag.str') // "Hi, how's it going?"
Results in the following alert:
导致以下警报：

Razor will HTML encode everything, so to prevent the ' from being encoded to ', you can use
Razor 将对所有内容进行 HTML 编码，因此为了防止 ' 被编码为'，您可以使用
alert('@Html.Raw(ViewBag.str)');
However, now you've got an actual ' in the middle of your string which causes a javascript error. To get around this, you can either wrap the alert string in double quotes (instead of single quotes), or escape the ' character. So, in your controller you would have
但是，现在您的字符串中间有一个实际的 ' ，这会导致 javascript 错误。为了解决这个问题，您可以将警报字符串用双引号（而不是单引号）括起来，或者转义 ' 字符。所以，在你的控制器中，你会有
ViewBag.str = "Hi, how\'s it going?";
