concatenating JavaScript strings

url: '/Administration/GetRoleList?name=&jtStartIndex=0d&jtPageSize=500&jtSorting=""',

Open in new window


I am trying to send empty strings.  

I get so confused with string concatenation in JavaScript when I am trying to build a string programMatically!!

I could use some help and some advice on how to keep straight when to use '  vs " and when to use "+" etc....

In Javascript you concatenate with a "+".

You can enclose literal strings in either ' or ". Whichever one you start with, you must end with. That's why if you are going to have double-quotes within your string, it's best to start and end it with single quotes.

But you can use the + sign to concatenate them all, regardless of how you quote (or double-quote) them.

var x = "This is string one. It's got a single quote in it.";
var y = 'This is string two. It "shows" double quotes in it.';
var z = x + " " + z;
alert(z);

Hmmm...okay.

So if I am trying to achieve this result:

 XHR finished loading: POST "http://localhost:40704/Administration/GetRoleList?name=&jtStartIndex=0&jtPageSize=50&jtSorting=Name%20ASC".

Open in new window


How would I do this?

Is:  

name=

the way you pass a null parameter (or empty string) ?

A few questions, in order to answer yours:

This string you gave:

Does any of it already exist in a javascript variable?
Do you want to show it as an alert (pop up), or on your webpage, or where?
