Question

I would like to form a link on the client end.

I think that need to be urlencoded but I am pretty confused with this. Is this right?

var link = document.createElement("a");

//addParams function just replaces the 0th and 1th occurrence with values 

a.link = url.addParams(valueO, value1); // url is /home/testpage.aspx?{0}={1}

Answer 1

• Shouldn’t that be link.href = url.addParams(valueO, value1);?

• And both value0 and value1 should be sent (individually) through either escape() or encodeURIComponent() (I believe the latter is recommended over escape()). You probably will want to do this in addParams() before you replace {0} and {1} in your URL string.

  You could also do something like addParams(encodeURIComponent(value0), encodeURIComponent(value1)) but in my opinion, that’s asking for trouble if you forget to encode some values in a call somewhere. It’d be better to move the encoding into the function itself.

• Here’s an explanation of what escape(), encodeURI(), encodeURIComponent() do and how they’re different and when to use each.
