I have a subdomain protected by a service similar to cloudflare. It checks if a visitor is human or not. To save bandwidth usage I want only one file to be loaded from this subdomain as indicator if the visitor is a bot or not. If it is not loaded, the service has blocked it as bot, and nothing should be shown.
I already thought of an ajax request before the page loads to check this.
var success = 0;
function myCall() {
var request = $.ajax({
url: "sub.example.com/hello.php",
type: "GET",
dataType: "html"
});
request.done(function() {
// Load page, because the request was successfull
$.ajax({
url: 'content.php', //This is the current file
type: "POST",
dataType:'json', // add json datatype to get json
data: ({load: true}),
success: function(data){
console.log(data);
}
})
});
Is there a better way to do this?
You may try this:
var success = 0;
function myCall() {
var request = $.ajax({
url: "sub.example.com/hello.php",
type: "GET",
dataType: "html",
success: function(){
$.ajax({
url: 'content.php', //This is the current file
type: "POST",
data: dat,
success: function(data){
console.log(data);
},
error: function(data){
console.log('Error!');
}
});
},
error: function(data){
console.log('Error!');
}
});
}

I am trying to use the following for a simple database query
$.ajax({
url: "trackingcodedata.php",
type: "GET",
dataType: 'json',
data:{option:1},
success: function(data) {
$('#js-tracking-code').val(data.tracking_code[0].js_tracking_code);
},
error: function(){
console.log("failed");
}
});
the url works fine in this form. What I really want to do is have the file in a sub directory. And call it the same way.
$.ajax({
url: "db/trackingcodedata.php",
type: "GET",
dataType: 'json',
data:{option:1},
success: function(data) {
$('#js-tracking-code').val(data.tracking_code[0].js_tracking_code);
},
error: function(){
console.log("failed");
}
});
The second version with the file in the db sub directory gives me a 500 error. The first one works fine. ????
I am going to print the response data from test.php in JSON format to print it on particular field
$.ajax({
type: 'POST',
url: 'test.php',
data: data,
success: function(response) {
var result = $.parseJSON(response);
$(document).ready(function(){
$("#test").click(function(){
$("#bemail").val(result.email);//when i prints only result than it displays [object object]
});
});
}
});
Try it like this . You have to put your ajax inside $(document).ready
$(document).ready(function(){
$.ajax({
type: 'POST',
url: 'test.php',
data: data,
success: function(response) {
var result = JSON.parse(response);
$("#bemail").val(result.email);
}
});
});
you are calling document.ready() inside the AJAX success handler which doesn't get invoked since AJAX call doesn't invoke the document loading again, DOM has already loaded and it loads only once in the life cycle of a page session.
This much should do
$.ajax({
type: 'POST',
url: 'test.php',
data: data,
success: function(response) {
var result = JSON.parse(response);
$("#bemail").val(result[0].email); //after you explained the JSON response
}
});
Your code is totally wrong, it should be
function displayEmail() {
$.ajax({
type: 'POST',
url: 'test.php',
data: data,
success: function(response) {
var result = $.parseJSON(response);
//Just Print the Result in Console using console.log(result)
$("#bemail").val(result.email);
}
});
}
$(document).ready(function() {
$("#test").click(function() {
displayEmail();
});
});
This is what I am trying to do. On a home page.. say /home.jsp, a user clicks on a link. I read value of the link and on the basis of which I call a RESTful resource which in turn manipulates database and returns a response. Interaction with REST as expected happens with use of JavaScript. I have been able to get information from REST resource but now I want to send that data to another JSP.. say /info.jsp. I am unable to do this.
I was trying to make another ajax call within success function of parent Ajax call but nothing is happening. For example:
function dealInfo(aparameter){
var requestData = {
"dataType": "json",
"type" : "GET",
"url" : REST resource URL+aparameter,
};
var request = $.ajax(requestData);
request.success(function(data){
alert(something from data); //this is a success
//I cannot get into the below AJAX call
$.ajax({
"type": "post",
"url": "info.jsp"
success: function(data){
alert("here");
("#someDiv").html(data[0].deviceModel);
}
});
How do I go about achieving this? Should I use some other approach rather than two Ajax calls? Any help is appreciated. Thank You.
You can use the following function:
function dealInfo(aparameter) {
$.ajax({
url: 'thePage.jsp',
type: "GET",
cache: false,
dataType: 'json',
data: {'aparameter': aparameter},
success: function (data) {
alert(data); //or you can use console.log(data);
$.ajax({
url: 'info.jsp',
type: "POST",
cache: false,
data: {'oldValorFromFirstAjaxCall': data},
success: function (info) {
alert(info); //or you can use console.log(info);
$("#someDiv").html(info);
}
});
}
});
}
Or make the AJAX call synchronous:
function dealInfo(aparameter) {
var request = $.ajax({
async: false, //It's very important
cache: false,
url: 'thePage.jsp',
type: "GET",
dataType: 'json',
data: {'aparameter': aparameter}
}).responseText;
$.ajax({
url: 'info.jsp',
type: "POST",
cache: false,
data: {'oldValorFromFirstAjaxCall': request},
success: function (info) {
alert(info); //or you can use console.log(info);
$("#someDiv").html(info);
}
});
}
In this way I'm using.
"type": "post" instead of type: 'post'
Maybe it will help. Try it please. For Example;
$.ajax({
url: "yourURL",
type: 'GET',
data: form_data,
success: function (data) {
...
}
});
In the success function I want to call a function. The problem is that ajax does not fire, so the data is never triggered and display. Here is my ajax call with a javascript function call in the success function.
$.ajax({
type: "POST",
url: "./api/login.php",
data: dataString,
cache: false,
success: function(data){
if(data){
//FUNCTION CALL WHEN USER LOGGING IN
retrieveUserBlogData();
window.location = "api/home.php";
}else{
$('.alert').show();
}
}
});
function retrieveUserBlogData(){
$.ajax({
type: "GET",
url: 'retrievePostData.php',
data: "",
dataType: 'json',
success: handleData
});
}
function handleData(data) {
alert(data);
var blog_file = data[3];
$('#imageDiv')
.append('<img id="blog_img" src="upload/' + blog_file + '"><br>');
}
I cant figure out why the ajax in the retrieveUserBlogData() function is not being triggered.
Any help would be appreciated Thanks.
Even if the AJAX succeeds, you are redirecting the browser to a different page after the first AJAX request:
window.location = "api/home.php";
So I would suggest removing that.
Try the following code for redirecting to another window
window.location.assign(URL);
then it may work.
Try it like this
$.ajax({
type: "POST",
url: "./api/login.php",
data: dataString,
cache: false,
success: function(data){
if(data){
//FUNCTION CALL WHEN USER LOGGING IN
retrieveUserBlogData();
}else{
$('.alert').show();
}
}
});
function retrieveUserBlogData(){
$.ajax({
type: "GET",
url: 'retrievePostData.php',
data: "",
dataType: 'json',
success: function(data){
alert(data);
var blog_file = data[3];
$('#imageDiv')
.append('<img id="blog_img" src="upload/' + blog_file + '"><br>');
window.location = "api/home.php";
}
});
}
Using Jquery AJAX to read a number from a server file, increment the number, and write the number back to the server file.
I can read the file fine, I just can't post to the file.
<script>
var counter = -1;
$.ajax({
type: "GET",
url: "counter.txt",
success: function(text) {
counter = text;
counter++;
$("#count").html(counter);
},
error: function() {
$("#count").html("Error!");
}
});
$.ajax({
type: "POST",
url: "counter.txt",
data: counter,
success: function() {
},
});
</script>
Ajax being a client-side method can't write to a file on the server.
You would need some middleware in PHP, ASP, Python etc to take the amends as posted data and write to the file.
Since Ajax is asynchronous, this piece of code
$.ajax({
type: "POST",
url: "counter.txt",
data: counter,
success: function() {
},
});
will be executed before you will get first number from server. You need to put this code inside "success" function
$.ajax(
type: "GET",
url: "counter.txt",
success: function(text) {
counter = text;
counter++;
$("#count").html(counter);
$.ajax({
type: "POST",
url: "counter.txt",
data: counter,
success: function() {
},
});
},
error: function() {
$("#count").html("Error!");
}
});
Also, you should just call some server side php method through Ajax, since you can't set anything through JavaScript on server.
So "post" Ajax URL should looks like
url: 'http://www.server.ca/set_vars?var=var_title&value=' + encodeURIcomponent(counter)
