Im trying to use messi jquery script on my site but I am unsure of how the load method it uses passes params on.
The example messi gives for creating a ajax call popup is:
Messi.load('test2.php', {params: {user: 'demo', password: '1234'}});
but i've tried both post and get method to capture the parameters in test2.php but without success.
for example
$user=$_POST['user'];
and
$get=$_GET['user'];
but both return a undefined index error
The load method is supposed to be an ajax call so I presumed it would be either a post or get request.
Is there another way I can capture the parameters?
Try with
$user = $_REQUEST['user'];
Anyway, have you loaded before jQuery? Messi script needs it to work!
Or, you can call your ajax request externally, then load a Messi popup with the ajax response.
$.get( "test2.php", { user: "username", password: "234234" } )
.done(function( data ) {
Messi.alert(data);
});
(if you take a look on the github Messi's library, that code makes an ajax call and then opens a Messi alert. This is the js library not minified: https://github.com/marcosesperon/Messi/blob/master/messi.js#L256 )

I have a custom form that posts to a 3rd party server as an appointment booking module. If i submit the form thru the action of the <form> tag i do recieve the email, but i would like to submit the form using $.POST so that i can alter the redirect URL.
I have jQuery running successfully on my site, and if i use:
$.post('URL', {data}).then(function () {alert('Form Submitted!')});
The redirect (or alert for this example) works fine, but the POST doesnt seem to actually run. Has anyone had a similar issue and found a way to resolve this?
ACTUAL CODE
I am using mailthis.to's API to avoid having to run a server just to do this
$('#sendForm').click(()=>{
$.post('https://mailthis.to/support#gadget-pro.com', {
Name:$('#Name').val(),
Email:$('#Email').val(),
Phone:$('#Phone').val(),
Device:$('#device').val(),
Repair:$('#repairType').val(),
Price:$('#price').val()
}).then(function (data) {
location.href = 'https://gadget-pro.com/formconfirm'
});
})
I would say to update your code to return back the page. you are likely not triggering the post to page properly or there is an error.
alos console.log the post data before to know what is being sent.
update your code to
console.log(data);
$.post('URL', {data}).then(function (retpage) {console.log(retpage)});
before we start apologies for the wording and lack of understanding - I am completely new to this.
I am hoping to run a php script using Ajax - I don't need to send any data to the php script, I simply need it to run on button press, after the script is run I need to refresh the body of the page. What I have so far:
HMTL Button with on click:
<font color = "white">Next Question</font>
JS Ajax call:
function AjaxCall() {
$.ajax({
url:'increment.php',
type: 'php',
success:function(content,code)
{
alert(code);
$('body').html(content);
}
});
}
this runs the php script but doesn't stay on the current page or refresh the body - has anyone got any ideas - apologies if this is completely wrong I'm learning - slowly.
Many thanks in advance.
**As a small edit - I don't want a user to navigate away from the page during the process
How about using load instead of the typical ajax function?
function AjaxCall() {
$(body).load('increment.php');
}
Additionally, if you were to use the ajax function, php is not a valid type. The type option specifies whether you are using GET or POST to post the request.
As far as the dataType option (which is what I think you mean), The Ajax doesn't care what technology the called process is using (like ASP or PHP), it only care about the format of the returned data, so appropriate types are html, json, etc...
Read More: http://api.jquery.com/jquery.ajax/
Furthermore, if you are replacing the entire body content, why don't you just refresh the page?
your ajax should be
function AjaxCall() {
$.ajax({
url:'increment.php',
type: 'post',
success:function(data)
{
console.log(data);
$('body').html(data);
}
});
}
if you want to learn ajax then you should refer this link
and if you just want to load that page then you can use .load() method as "Dutchie432" described.
If you are going to fire a javascript event in this way there are two ways to go about it and keep it from actually trying to follow the link:
<font color = "white">Next Question</font>
Note the return false;. This stops the following of the link. The other method would be:
<font color = "white">Next Question</font>
Note how this actually modifies the href to be a javascript call.
You can study about js and ajax here http://www.w3schools.com/ajax/default.asp will help a lot. Of course all js functions if called from internal js script should be inside <script></script> and if called from external you call the js gile like <script src"somejs.js"></script> and inside js there is no need for <script> tags again. Now all those function do not work by simply declaring them. So this:
function sayHello(){
alert("Happy coding");
}
doesn't work because it is just declared and not called into action. So in jQuery that you use after we declare some functions as the sayHello above we use:
jQuery(document).ready(function($){
sayHello();
});
Doing this we say that when everything is fully loaded so our DOM has its final shape then let the games begin, make some DOM manipulations etc
Above also you don't specify the type of your call meaning POST or GET. Those verbs are the alpha and omega of http requests. Typically we use GET to bring data like in your case here and POST to send some data for storage to the server. A very common GET request is this:
$.ajax({
type : 'GET',
url : someURL,
data : mydata, //optional if you want to send sth to the server like a user's id and get only that specific user's info
success : function(data) {
console.log("Ajax rocks");
},
error: function(){
console.log("Ajax failed");
}
});
Try this;
<script type="text/javascript">
function AjaxCall() {
window.location.reload();
}
</script>
<body>
<font color = "white">Next Question</font>
</body>
On one of my pages I have "tracking.php" that makes a request to another server, and if tracking is sucessful in Firebug Net panel I see the response trackingFinished();
Is there an easy way (built-in function) to accomplish something like this:
If ("tracking.php" responded "trackingFinished();") { *redirect*... }
Javascript? PHP? Anything?
The thing is, this "tracking.php" also creates browser and flash cookies (and then responds with trackingfinished(); when they're created). I had a JS that did something like this:
If ("MyCookie" is created) { *redirect*... }
It worked, but if you had MyCookie in your browser from before, it just redirected before "track.php" had the time to create new cookies, so old cookies didn't get overwritten (which I'm trying to accomplish) before the redirection...
The solution I have in mind is to redirect after trackingFinished(); was responded...
I think the better form in javascript to make request from one page to another, without leaving the first is with the ajax method, and this one jQuery make it so easy, you only have to use the ajax function, and pass a little parameters:
$.post(url, {parameter1: parameter1value, param2: param2value})
And you can concatenate some actions:
$.post().done(function(){}).fail(function(){})
And isntead of the ajax, you can use the $.post that is more easy, and use the done and fail method to evaluate the succes of the information recived
As mentioned above, AJAX is the best way to communicate between pages like this. Here's an example of an AJAX request to your track.php page. It uses the success function to see if track.php returned 'trackingFinished();'. If it did then it redirects the page 'redirect.php':
$.ajax({
url: "track.php",
dataType: "text",
success: function(data){
if(data === 'trackingFinished();'){
document.location = 'redirect.php';
}
}
});
The example uses JQuery.
Having trouble accessing javascript code in a mixed html/js ajax response. jQuery ajax doc states:
If html is specified, any embedded JavaScript inside the retrieved
data is executed before the HTML is returned as a string
Which I can confirm by adding a simple snippet to the html reply:
<script type="text/javascript"> alert($(this)); </script>
How then to retain access to the js code vs. one-and-done execution?? Trying to implement a modal login (to prevent data loss on session timeout in form submission screens). Of course I need to be able to access the ajax'd js code to then validate email/password fields and ajax authenticate user credentials on the remote server.
Here's the modal login coffeescript snippet:
# submit form
$.ajax
success: (data) -> ...
error: (data) ->
popAuth(data.responseText) if(data.status == 401)
popAuth = (title) ->
$.fancybox({
href: "/login"
ajax: { type: "GET" }
title: title
})
Perhaps I can add a success callback to popAuth() ajax options to store the returned js code? How about jQuery "live" handler? Unfortunate that this scenario is not as straight forward as one would hope ;-) I have seen $.getScript as an option, but would prefer to not separate html from js since server-side already assembles html + js and the original ajax call pulls it all down in one go. (i.e. avoid creating a dedicated server-side controller to send back js file content bundle)
I am of course open to alternative solutions to workaround this issue. For example, I could store login fields and js login validation code on every screen (JVM CRUD application living behind WordPress front end so every screen is basically auth required) in a hidden div, and then pop the modal login window "locally", which I assume would get around the annoying one-and-done js execution of remote ajax content.
Anyway, Ideas appreciated! client-side is both wonderfully simple and...horribly complex ;-)
Ok, fending off the veritable deluge of responses, I'll take a stab myself.
As I understand it now, since mixed html/js content is one-and-done executed, we have one chance to capture ajax response js code and bind it to current scope.
First, in the original ajax call (i.e. form submit that returns a potential 401 not authorized status) set the context of the modal login's ajax setup to $(this), the currently executing scope that contains jquery validation and other shared js code needed for modal login ajax submit to work.
In my case, using fancybox, adding context param it now looks like:
popAuth = (title) ->
$.fancybox({
href: "/login"
ajax: { type: "GET" }
context: $(#)
title: title
})
Then, since the parent window contains the majority of needed javascript, the only requirement is to create a js file that binds modal login form button click event to validation and $.ajax submission.
# login.coffee
jQuery ->
$('#loginSubmit').click (e) ->
e.preventDefault()
isValid = $('#loginForm').validate().form()
if isValid
$('#spinner').show()
$.ajax
data: $('#loginForm').serialize()
success: (data) ->
$('#status').fadeOut()
location.href = '/foo'
error: (data) ->
$('#status > div').html( data.responseText )
$('#status').fadeIn()
complete: () ->
$('#spinner').hide()
Done, all good, works ;-)
I had a problem with jquery's post api.
$(".MGdi").click(function () {
id=$(this).attr("rel")
$.post( 'Mdeger.asp?cmd=MG', { id: id, drm: $(this).html()} ,
function( data ) {
var $response=$(data);
var snc = $response.find('#snc').html();
alert(snc);
},"application/x-www-form-urlencoded");
});
Another way is:
$(".Pasif").click(function () {
id=$(this).attr("rel")
$.post( 'Mdeger.asp?cmd=Pasif', { id: id, drm: $(this).html()} ,
function( data ) {
$(this).html(data);
alert(data)
},"application/x-www-form-urlencoded");
});
Everything is OK on serverside but clientside's success function does nothing.
Even basic codes like alert("hoho"); success not triggering.
this usually happens when respond couldn't be parsed. you should check the respond using firebug or similar debugging tool.
especially the methods that expects json data, strictly validates the respond and if there is anything invalid it just does nothing, no-error, no-warning, no-exception.
when your callback function doesn't run, you should suspect that your respond isn't correct.
// Türkçe özet
uzun lafın kısası dönüş değerinde bir terslik varsa dönüş fonksiyonu çalışmayacaktır. sunucudan gelen değerleri iyice kontrol etmekte fayda var. jquery dönüş değerinde veya dönüş fonksiyonunda bir hata olursa seni uyarmadan işi sonlandırıyor.
I had this problem as well. It turns out I was making an AJAX call to the same domain, but on a different port, which is not allowed (for security reasons) in Javascript.
See this relevant question for more info:
How do I send an AJAX request on a different port with jQuery?
I was very surprised that the AJAX call would POST/GET to the server, (which I was able to verify by looking at the server log) but that the response was never read. I would have thought that both sending and receiving would be disallowed.
I had this error too, and that was a stupid problem : I set dataType to "json" in my JS, but the page called was returning plain HTML. And this cause to not fire the success function at all.
