传递具有特殊字符的字符串

I am trying to pass strings with spaces and special characters, but its getting error and nothing is working. e.g.

 <img onclick='addKeyword("celebritynews&gossip");' src="images/plus.png" >

but the '&' inside string celebritynews&gossip is breaking the code.

I figured out that the problem is in addKeyword function, I'd used the following code for defining a variable named url,

function addKeyword(categoryId){
var url = "addKeyword.php?uid=" + user_id + "&categoryId=" + categoryId + "&keyword=" + $("#keyword_" + categoryId).attr("value");
}

and that $("#keyword_" + categoryId) is causing problem. Any way to solve that?

    Assuming you are passing the string on a URL, the parameter values need to be URL encoded.

    ...SUMMARY EDIT...

    The & is interpreted as HTML and must be HTML encoded, specifically &amp;

    HTML

    <img onclick='addKeyword("celebritynews&amp;gossip");' src="images/plus.png" />
    

    JavaScript

    Use encodeURIComponent(s).

    var url = "addKeyword.php?uid=" + encodeURIComponent(user_id) + "&categoryId=" + encodeURIComponent(categoryId) + "&keyword=" + encodeURIComponent($("#keyword_" + categoryId).attr("value"));
