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?
