Ajax post does not work after document ready - javascript

I want to make an Ajax call after my document is ready. Here is my code :
<script>
$(window).bind("load", function () {
getCategories();
});
</script>
<script>
function getCategories() {
$.ajax({
type: "POST",
url: '#Url.Action("GetAllCategoryTest", "Category")',
dataType: "html",
contentType: "application/json",
async: false,
success: function (result) {
var categoryList = JSON.parse(result);
$.each(categoryList.result, function (i) {
$("#menuCategory").append('<li>' + categoryList.result[i].CategoryName + '</li>');
});
}
});
}
</script>
My ajax post works without using window.bind but I have to run my ajax post after my document is loaded.

<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script>
<script>
$(document).ready(function() {
getCategories();
});
function getCategories() {
$.ajax({
type: "POST",
url: '#Url.Action("GetAllCategoryTest", "Category")',
dataType: "html",
contentType: "application/json",
async: false,
success: function(result) {
var categoryList = JSON.parse(result);
$.each(categoryList.result, function(i) {
$("#menuCategory").append('<li>' + categoryList.result[i].CategoryName + '</li>');
});
}
});
}
</script>

how to call function inside ajax call

I am trying to call function within ajax success block which is not happening.
Below I have given code which i was tried.
$("#form-data").submit(function(e) {
e.preventDefault();
var me = this;
$.ajax({
type: "POST",
url: "{{route('storeData.store')}}",
data: fd,
processData: false,
contentType: false,
success: function(data) {
me.callFunc(); // here i need to call that fucntion once data is stored in database
}
});
})
$(document).ready(function(e) { // here i need to call that fucntion when page loads
this.callFunc();
})
function callFunc() { // this is the function needs to call
$.ajax({
type: "GET",
url: "{{route('getData.get')}}",
success: function(data) {
console.log("output data", data)
}
})
}
Call your "callFunc()" without me / this as per below.
$("#form-data").submit(function(e) {
e.preventDefault();
$.ajax({
type: "POST",
url: "{{route('storeData.store')}}",
data: fd,
processData: false,
contentType: false,
success: function(data) {
callFunc(); // here i need to call that fucntion once data is stored in database
}
});
})
$(document).ready(function(e) { // here i need to call that fucntion when page loads
callFunc();
})
function callFunc() { // this is the function needs to call
$.ajax({
type: "GET",
url: "{{route('getData.get')}}",
success: function(data) {
console.log("output data", data)
}
})
}
You don't have to use this
$(document).ready(function (e) {
function callFunc() { // this is the function needs to call
$.ajax({
type: "GET",
url: "{{route('getData.get')}}",
success: function (data) {
console.log("output data", data)
}
})
}
$("#form-data").submit(function (e) {
e.preventDefault();
$.ajax({
type: "POST",
url: "{{route('storeData.store')}}",
data: fd,
processData: false,
contentType: false,
success: function (data) {
callFunc(); // here i need to call that fucntion once data is stored in database
}
});
});
callFunc(); // here i need to call that fucntion when page loads
});
Your function is globally available so just call it like any other javascript function inside any other function
callFunc()

How to do Ajax requests?

Am trying to make wikipedia viewer for my freecodecamp project. But the ajax request fails every time. It does not return anything.
var url, value;
$(document).ready(function() {
$("button").on("click", function() {
value = $("input").val();
var url = "https://en.wikipedia.org/w/api.php?action=opensearch&search=" +
value + "&format=json&callback=?";
$.ajax({
type: "GET",
url: url,
async: false,
dataType: "json",
//jsonp: "callback",
success: function(data) {
console.log(data);
}
});
});
});
set dataType: 'jsonp'
remove &callback=? from the url (that's the default that jQuery will use anyway
example
var value = "google";
var url = 'https://en.wikipedia.org/w/api.php?action=opensearch&search='+ value + '&format=json';
$.ajax({
type: 'GET',
url: url,
dataType: 'jsonp',
success: function (data)
{
console.log(data);
}
});
<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script>
Use this code:
<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script>
<input type="text" id="search" /><br /><br />
<button>Click here</button>
<script>
var url, value;
$(document).ready(function() {
$("button").on("click", function() {
value = $("input").val();
var url = "https://en.wikipedia.org/w/api.php?action=opensearch&search=" +
value + "&format=json";
$.ajax({
type: "GET",
url: url,
async: false,
dataType: "jsonp",
success: function(data) {
console.log(data);
}
});
});
});
</script>

JSP AJAX return NULL

i using JQuery Ajax to call REST api in jsp but it return null no matter how i call but it can work in html. is there any way to solve this problem. Cant seem to find a solution in the net.
$(document).ready(function () {
alert('ready');
var accessKey = 'xkg8VRu6Ol+gMH+SUamkRIEB7fKzhwMvfMo/2U8UJcFhdvR4yN1GutmUIA3A6r3LDhot215OVVkZvNRzjl28TNUZgYFSswOi';
var thisUrl = 'http://www.onemap.sg/API/services.svc/getToken?accessKEY=' + accessKey;
$.ajax({
type: "GET",
url: thisUrl,
dataType: 'application/json',
success: function (data) {
alert('data is:' + data.GetToken[0].NewToken);
}
});
alert(thisUrl);
});
dataType should be jsonp
$(document).ready(function () {
var thisUrl = 'http://www.onemap.sg/API/services.svc/getToken?accessKEY=' + accessKey;
$.ajax({
type: "GET",
url: thisUrl,
dataType: 'jsonp',
success: function (data) {
console.log(data)
alert('data is:' + data.GetToken[0].NewToken);
}
});
});
Refer to this article:
http://www.isgoodstuff.com/2012/07/22/cross-domain-xml-using-jquery/
You only need "jquery.xdomainajax.js" that is there in the sample source-code to make it work.
$.ajax({
url: 'https://asdf/asdf',
dataType: "xml",
type: 'GET',
success: function(res) {
var myXML = res.responseText;
alert(myXML);
}
});
