通过单Qoute字符串从MVC剃刀的JavaScript [英] Passing strings with Single Qoute from MVC Razor to JavaScript

问题描述

这看起来很简单很尴尬。然而，第一个问题是来自新ViewBag在MVC 3.0（剃刀）传递一个值到一个JavaScript块的时候，这是做了正确的方法是什么？更重要的是，在这里，你如何成为＆＃39应用适当的字符串替换code至prevent一个单引号如下得到警报？

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?

添加此成一个脚本块：

alert('@ViewBag.str')   // "Hi, how's it going?"

结果如下警告：

推荐答案

剃刀将HTML带code一切，所以到prevent的'被连接coded到＆放;＃39; ，您可以用

Razor will HTML encode everything, so to prevent the ' from being encoded to ', you can use

alert('@Html.Raw(ViewBag.str)');

不过，现在你已经得到了你的字符串中间这会导致JavaScript错误的实际。为了解决这个问题，你可以包裹在双引号警报字符串（而不是单引号），或逃避字符。所以，在你的控制器你会

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

ViewBag.str = "Hi, how\\'s it going?";
