How to pass parameters in GET requests with jQuery

Question

How should I be passing query string values in a jQuery Ajax request? I currently do them as follows but I'm sure there is a cleaner way that does not require me to encode manually.

$.ajax({
    url: "ajax.aspx?ajaxid=4&UserID=" + UserID + "&EmailAddress=" + encodeURIComponent(EmailAddress),
    success: function(response) {
        //Do Something
    },
    error: function(xhr) {
        //Do Something to handle error
    }
});

I’ve seen examples where query string parameters are passed as an array but these examples I've seen don't use the $.ajax() model, instead they go straight to $.get(). For example:

$.get("ajax.aspx", { UserID: UserID , EmailAddress: EmailAddress } );

Hello @kartik,

Use data option of ajax. You can send data object to server by data option in ajax and the type which defines how you are sending it (either POST or GET). The default type is GET method

Try this

$.ajax({
  url: "ajax.aspx",
  type: "get", //send it through get method
  data: { 
    ajaxid: 4, 
    UserID: UserID, 
    EmailAddress: EmailAddress
  },
  success: function(response) {
    //Do Something
  },
  error: function(xhr) {
    //Do Something to handle error
  }
});

And you can get the data by (if you are using PHP)

 $_GET['ajaxid'] //gives 4
 $_GET['UserID'] //gives you the sent userid

In aspx, I believe it is (might be wrong)

 Request.QueryString["ajaxid"].ToString(); 

Hope it helps!!

Thank you!!
