Uncaught SyntaxError: Invalid or unexpected token

问题:

I have a razor syntax like this:

   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:

<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:

"Uncaught SyntaxError: Invalid or unexpected token",

and this part is underlined:

    **</a>  </td>**

I am a beginner so I get stuck in syntax a lot. If it is that then please help me out.

You should pass @item.email in quotes then it will be treated as string argument

<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.

The accepted answer work when you have a single line string(the email) but if you have a

multiline string, the error will remain.

Please look into this matter:

<!-- 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:

<a href="#" onclick="Getinfo(`@item.MultiLineString`)">6/16/2016 2:02:29 AM</a>
