});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>call ajax
//I use blockUI for loading...
$.blockUI({ message: '<h3>Please wait a moment...</h3>' });
$.ajax({
type: "POST",
url: '@Url.Action("ExportExcel","YourController")', //call your controller and action
contentType: "application/json; charset=utf-8",
dataType: "json",
}).done(function (data) {
//console.log(data.result);
$.unblockUI();
//get the file name for download
if (data.fileName != "") {
//use window.location.href for redirect to download action for download the file
window.location.href = "@Url.RouteUrl(new
{ Controller = "YourController", Action = "Download"})/?file=" + data.fileName;
