Add Html.Partial to Javascript

Question

I want to set a string in Javascript with an ASP.NET Html.Partial View. The problem is that Html.Partial gives an HtmlString and not a Javascript string which i can handle for example with JQuery.

Javascript code:

myfunction= function () {
   ...
   var badge=@Html.Partial("_UserBadge",User.Identity.Name).ToString();
   ....
   $("#myNode").append(badge);
};

Html-Partial "_UserBadge.cshtml":

@model WT.Models.ttUser

<div style="..">
...some more lines html...
</div>

My problem is that ' at beginning and '+ at the end of each line isn't added. How can i resolve the problem?

The code results to:

var badge=
<div style="..">
...some more lines html...
</div>;

instead of a javascript string:

var badge=
'<div style="..">   '+
'...some more lines html...   '+
'</div>  ';

Answer 1

Couldn't you just use something like:

var badge='@Html.Partial("_UserBadge",User.Identity.Name).Replace( "\n", "\\n" ).Replace( "'", "\\'" )';

You suggest in your question that you want the result to be:

'<div style="..">   '+
'...some more lines html...   '+
'</div>  ';

but note that this is equivalent to:

'<div style="..">   ...some more lines html...   </div>  ';

which might not be what you actually want (since this is different from the _UserBadge page).

What you probably actually want is something more like this:

'<div style="..">\n...some more lines html...\n</div>';

The example replaces newline characters with "\\n" which will be interpreted by javascript as a newline character. Finally, you'll need to replace single quotes with "\\'" to ensure that you don't accidentally terminate the string before you meant to.

I think you could use Json.NET for serializing objects to json (it will escape all the string characters).

Something like:

@using Newtonsoft.Json

myfunction= function () {
   ...
   var badge=@(Html.Raw(JsonConvert.SerializeObject(Html.Partial("_UserBadge",User.Identity.Name))));
   ....
   $("#myNode").append(badge);
};
