Uncaught SyntaxError: Invalid or unexpected token
提问by Himaan Singh
I have a razor syntax like this:
我有一个像这样的剃刀语法：
foreach(var item in model)
{
<td><a href ="#" onclick="Getinfo(@item.email);" >6/16/2016 2:02:29 AM</a> </td>
}
My javascript that recieves the request goes like this:
我收到请求的 javascript 是这样的：
<script type="text/javascript" src="~/Scripts/jquery-1.9.1.js"></script>
<script type="text/javascript">
function Getinfo(elem) {
var email = document.getElementById(elem).innerHTML;
}
</script>
When clicking on the href link, I get the following error in the console of the browser:
单击 href 链接时，我在浏览器的控制台中收到以下错误：
"Uncaught SyntaxError: Invalid or unexpected token",
"未捕获的语法错误：无效或意外的令牌",
and this part is underlined:
这部分有下划线：
**</a> </td>**
I am a beginner so I get stuck in syntax a lot. If it is that then please help me out.
我是一个初学者，所以我经常被语法困住。如果是这样，那么请帮助我。

You should pass @item.emailin quotes then it will be treated as string argument
您应该传入@item.email引号，然后它将被视为字符串参数
<td><a href ="#" onclick="Getinfo('@item.email');" >6/16/2016 2:02:29 AM</a> </td>
Otherwise, it is treated as variable thus error is generated.
否则，它被视为变量，从而产生错误。

The accepted answer work when you have a single line string(the email) but if you have a
当您有一个单行字符串（电子邮件）但如果您有一个
multiline string, the error will remain.
多行字符串，错误仍然存在。
Please look into this matter:
请看一下这个问题：
<!-- start: definition-->
@{
dynamic item = new System.Dynamic.ExpandoObject();
item.MultiLineString = @"a multi-line
string";
item.SingleLineString = "a single-line string";
}
<!-- end: definition-->
<a href="#" onclick="Getinfo('@item.MultiLineString')">6/16/2016 2:02:29 AM</a>
<script>
function Getinfo(text) {
alert(text);
}
</script>
Change the single-quote(') to backtick(`) in Getinfo as bellow and error will be fixed:
将 Getinfo 中的单引号（'）更改为反引号（`），如下所示，错误将得到修复：
<a href="#" onclick="Getinfo(`@item.MultiLineString`)">6/16/2016 2:02:29 AM</a>

I also had an issue with multiline strings in this scenario. @Iman's backtick(`) solution worked great in the modern browsers but caused an invalid character error in Internet Explorer. I had to use the following:
在这种情况下，我也遇到了多行字符串的问题。@Iman 的反引号(`) 解决方案在现代浏览器中运行良好，但在 Internet Explorer 中导致无效字符错误。我不得不使用以下内容：
'@item.MultiLineString.Replace(Environment.NewLine, "<br />")'
Then I had to put the carriage returns back again in the js function. Had to use RegEx to handle multiple carriage returns.
然后我不得不将回车再次放回js函数中。不得不使用 RegEx 来处理多个回车。
// This will work for the following:
// "hello\nworld"
// "hello<br>world"
// "hello<br />world"
$("#MyTextArea").val(multiLineString.replace(/\n|<br\s*\/?>/gi, "\r"));
