How to encode the following URL using Javascript or jQuery properly?

All I want to do is encode the following link properly, but for some reason "#" is giving me a problem:

var text = "hello,开发者_StackOverflow社区 how are you? &am fine"
var link = "http://example.com/test#zzzzzzzzz"


url = "http://twitter.com/share?url=" + link + "&text" + text;
$("#twitter a").attr("href", url)

I tried encodeURI or encodeURIComponent, but still have issue with "#". If I manually replace "#" with "%23", then for some reason the code is encoded again. Does the jQuery attr() preform any encoding at all?

EDIT Trying escape produces

http://twitter.com/share?url=http%253A//example.com/test%2523zzzzzzzz

Not sure where the "%25" is coming from rather than just %23

Using encodeURIComponent generates the following after doing $("#twitter a").attr("href", url). Where is the %25 is coming from?

http://twitter.com/share?url=http%253A%252F%252Fexample.com%252Ftest%2523zzzzzzzz

encodeURIComponent should work for you:

var text = "hello, how are you? & fine";
var link = "http://example.com/test#zzzzzzzzz";

var url = "http://twitter.com/share?url=" + encodeURIComponent(link) + "&text=" + encodeURIComponent(text);

$('#twitter a').attr('href', url);

encodeURIComponent is not "complete", you can use a custom function like this (taken from http://phpjs.org/functions/urlencode/ ) :

function encode(toEncode) {
    return encodeURIComponent(toEncode)
        .replace(/!/g, '%21')
        .replace(/'/g, '%27')
        .replace(/\(/g, '%28')
        .replace(/\)/g, '%29')
        .replace(/\*/g, '%2A');
}

Example : var url = encode(url_plain_text);

According to Firebug:

>>> encodeURIComponent("http://example.com/test#zzzzzzzzz")
"http%3A%2F%2Fexample.com%2Ftest%23zzzzzzzzz"

What issues are you having with the '#'?

encodeURIComponent works fine for me. we can give the url like this in ajax call.The code shown below :

$.ajax({
            cache: false,
            type: "POST",
            url: "http://atandra.mivamerchantdev.com//mm5/json.mvc?Store_Code=ATA&Function=Module&Module_Code=thub_connector&Module_Function=THUB_Request",
            data: "strChannelName=" + $('#txtupdstorename').val() + "&ServiceUrl=" + encodeURIComponent($('#txtupdserviceurl').val()),
            dataType: "HTML",
            success: function (data) {
            },
            error: function (xhr, ajaxOptions, thrownError) {
            }
        });
