To call an asynchronous function synchronously in javascript


 we are trying to change some calls in the application from sync to async then i read the post

"Call An Asynchronous Javascript Function Synchronously" so when i call the callThis() I am getting the output as: "Success" "failure" but I need the output as "Success" "KATE success"

Can you guys suggest me a solution for this, not the callback or timeout but still an efficient technique when changed from sync to async

function callThis()
{
    if(kate())
    {
      console.log("KATE success")
    }
 else
  {
   console.log("failure")
  }
}
function kate()
{
  $.ajax({
        url: "www.google.com" (http://www.google.com),
        type: 'get',
        async: true,
        timeout: 10000,
        success: function (data) {
            console.log("Success");
        },
        error: function () {
            console.log("FAIL!!!");
        }
    });
}

Solution

  • The solution isn't to call it synchronously, but to work with the asynchronous nature of ajax

    function callThis() {
        kate().done(function(result) {
            if ( result ) {
                console.log("KATE success")
            } else {
                console.log("failure")
            }
        }).fail(function(error) {
            console.log(error);
        });
    }
    
    function kate() {
        return $.ajax({
            url: "www.google.com",
            type: 'get',
            async: true,
            timeout: 10000
        });
    }
    

    note that getting google.com will fail due to the same-origin policy
