Add URL.Action to javascript method in Razor View

Question

I have a question on how to put my Url Action to razor view:

@Html.EditorFor(m => m.MyTypes, false, new {id = "myId", onchange = "onMyTypeChange('Url.Action("GetMyFields", "MyController")')"})

Do you have any idea how to fix it ?

where is the leading '? you have an ending ' after "MyController")' but where is the leading one? — Grizzly

@BviLLe_Kid: Not true. Only reserved keywords need to be prefixed with @, such as @class, because class is a keyword and will be misinterpreted otherwise. id is not a keyword, and is fine. — Chris Pratt

@ChrisPratt ahh okay, I didn't know that. But his onchange needs to be prefixed with @, right? — Grizzly

There seems to be a couple of problems in your syntax for this line of code.

@Html.EditorFor(m => m.MyTypes, false, new {id = "myId", onchange = "onMyTypeChange('Url.Action("GetMyFields", "MyController")')"})

Your second parameter false is useless, since that technically should be of type string since it is for a templateName based on this.

Also as Chris Pratt and I were discussing, in MVC 5.1+ you have to pass your HTML attributes with new { htmlAttributes = new {...} }.

This should help in solving your issue.

@Html.EditorFor(m => m.MyTypes, new { htmlAttributes = new { id = "myId", onchange = "onMyTypeChange('" + Url.Action("GetMyFields", "MyController") + "')" } })
