ajax open() 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: 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>
