Topic awaiting preservation: The use of JavaScript encodeURI function (Page 1 of 1)

I found out that if I'm using encodeURI function on string contains '&' character, it wont pass correctly to the server.
Example:
If the parameter value is virLocation7,Israel At&T
By using escape function we get: virLocation7%2CIsrael%20At%26T
By using encodeURI function we get: virLocation7,Israel%20At&T

I got the server parameter for the first case (escape) and it was correct (virLocation7,Israel At&T).
I got the server parameter for the second case (encodeURI) and it was partial (virLocation7,Israel At).

As far as I know we should replace the use of "escape" with "encodeURI" function.
Is there is a new way to send GET requests using parameter values contains "&"?

Is this URI becoming the value of an HTML attribute at any point? For instance, are you creating the code

<a href="...AT&T...">...</a>

? If so, you must replace all ampersands (& with &amp;amp;

No.
I'm doing something like the following code:

function OpenURLWithParams(url, params){
url += "?";
for(var i=0; i<params.length; i++){
if(i > 0) url += "&";
url += params[i].key + "=" + encodeURI(params[i].value);
}

window.open(url);
}

I found it.
I have to use encodeURIComponent instead.
