ajax calls code example

Example 1: ajax request

$.ajax({
       url : 'more_com.php', //PHP file to execute
       type : 'GET', //method used POST or GET
       data : {variable1 : "some data"}, // Parameters passed to the PHP file
       success : function(result){ // Has to be there !
           
       },

       error : function(result, statut, error){ // Handle errors

       }

    });

// NOTE : Parameters will be available either through $_GET or $_POST according
// to the method you choosed to use. 
// Here you will get your variable "variable1" this way : $_GET['variable1']

Example 2: ajax call

$.ajax({
        url: "Url",
        dataType: "json",
        type: "Post",
        async: true,
        data: {"Key":value,"Key2":value2},
        success: function (data) {
                
        },
        error: function (xhr, exception, thrownError) {
            var msg = "";
            if (xhr.status === 0) {
                msg = "Not connect.\n Verify Network.";
            } else if (xhr.status == 404) {
                msg = "Requested page not found. [404]";
            } else if (xhr.status == 500) {
                msg = "Internal Server Error [500].";
            } else if (exception === "parsererror") {
                msg = "Requested JSON parse failed.";
            } else if (exception === "timeout") {
                msg = "Time out error.";
            } else if (exception === "abort") {
                msg = "Ajax request aborted.";
            } else {
                msg = "Error:" + xhr.status + " " + xhr.responseText;
            }
            if (callbackError) {
                callbackError(msg);
            }
           
        }
    });

Example 3: how to make ajax request javascript

//Change the text of a <div> element using an AJAX //request:
//using JQuery


$("button").click(function(){
  $.ajax({url: "demo_test.txt", success: function(result){
    $("#div1").html(result);
  }});
});



//To send a request to a server, we use the open() //and send() methods of the XMLHttpRequest object:
// Javascript


xhttp.open("GET", "ajax_info.txt", true);
xhttp.send();

//example below
<html>
<body>

<h1>The XMLHttpRequest Object</h1>

<button type="button" onclick="loadDoc()">Request data</button>

<p id="demo"></p>


<script>
function loadDoc() {
  var xhttp = new XMLHttpRequest();
  xhttp.onreadystatechange = function() {
    if (this.readyState == 4 && this.status == 200) {
      document.getElementById("demo").innerHTML = this.responseText;
    }
  };
  xhttp.open("GET", "demo_get.asp", true);
  xhttp.send();
}
</script>

</body>
</html>

Example 4: ajax calls

AJAX is allowing the Web page to retrieve small amounts of data from the
server without reloading the entire page. It is used for creating
fast and dynamic web pages.
There are several Wait methods I use to handle
AJAX calls. I add these pieces of code to my AJAX
testing code to handle it.
1. Explicit Waits
webdriver driver = new firefoxdriver();
driver.get("http://somedomain/url_that_delays_loading");
webelement mydynamicelement = (new webdriverwait(driver,10))
.until(expectedconditions.presenceofelementlocated(by.id("myd
ynamicelement")));
2. Implicit Waits
I also go for Implicit Waits, where I can decide on a
certain amount of time require WebDriver to poll the DOM for.  
 In this case your WebDriver will keep looking for an element(s),
 if it had been unavailable immediately. The default
time is set as 0, which can be easily adjusted as you may prefer.
In addition, this set wait time lasts as long as your browser is
open, so the time to search for any element on the page will be
the same.
webdriver driver = new firefoxdriver();
driver.manage().timeouts().implicitlywait(10,
timeunit.seconds);
driver.get("http://somedomain/url_that_delays_loading");
webelement mydynamicelement =
driver.findelement(by.id("mydynamicelement"));
