ASP.NET MVC - bug on razor when displaying single quote

Question

I just noticed when I do something like this:

@{
    String var1 = "there's error to this string";
}

<script>
    alert('@var1');
</script>

when I start running this and I look at alert box, the single quote character is transforming into weird display starting with #.

but when I just directly placing the string value to alert box, it works as expected:

<script>
    alert("there's error to this string");
</script>

I hope somebody could explain here why it happens.

您需要对字符串进行Javascript编码，然后告诉Razor不要对其进行HTML编码：

@Html.Raw(HttpUtility.JavaScriptStringEncode(var1))
