jQuery $.post - do I have to encode the URL parameter?

I'm making an AJAX call with $.post(url, cb). The URL I'm passing in could potentially have weird characters like spaces, &, ? and so on.

Do I have to use $.post(encodeURIComponent(url), cb)?

url is something like /foo/weird-char§.开发者_如何学Go

You will have to use encodeURIComponent() but not on the entire URI, only on the data part (weird and chars in your example). The URL and the ? & separating the parameters must stay intact. If you encode the entire URI, it will become unusable.

If you would add the data as POST data using the data parameter:

url = "/foo/possible";
$.post(url, { "weird": "f2(90§§$", "chars": "ß1028490" });

jQuery's Ajax functions would take care of URL encoding the data automatically.

Yes, you would need to encode the keys and values in the query string (but not the ? which separates the path from the query arguments and the & which separates the query arguments). This is built into jQuery if you use the data parameter of the $.post, like so:

$.post(url, { name: "John", time: "2pm" }, cb);

I'm using MVC3/EntityFramework as back-end, the front-end consumes all of my project controllers via jquery, posting directly (using $.post) doesnt requires the data encription, when you pass params directly other than URL hardcoded. I already tested several chars i even sent an URL(this one http://www.ihackforfun.eu/index.php?title=update-on-url-crazy&more=1&c=1&tb=1&pb=1) as a parameter and had no issue at all even though encodeURIComponent works great when you pass all data in within the URL (hardcoded)

Hardcoded URL i.e.>

 var encodedName = encodeURIComponent(name);
 var url = "ControllerName/ActionName/" + encodedName + "/" + keyword + "/" + description + "/" + linkUrl + "/" + includeMetrics + "/" + typeTask + "/" + project + "/" + userCreated + "/" + userModified + "/" + status + "/" + parent;; // + name + "/" + keyword + "/" + description + "/" + linkUrl + "/" + includeMetrics + "/" + typeTask + "/" + project + "/" + userCreated + "/" + userModified + "/" + status + "/" + parent;

Otherwise dont use encodeURIComponent and instead try passing params in within the ajax post method

 var url = "ControllerName/ActionName/";   
 $.post(url,
        { name: nameVal, fkKeyword: keyword, description: descriptionVal, linkUrl: linkUrlVal, includeMetrics: includeMetricsVal, FKTypeTask: typeTask, FKProject: project, FKUserCreated: userCreated, FKUserModified: userModified, FKStatus: status, FKParent: parent },
 function (data) {.......});
