Why does this simple ajax show an alert with "error"?
<script type="text/javascript" src="js/jquery-1.7.2.js"></script>
<script type="text/javascript">
$(document).ready( function(){
$.ajax({
url: "http://www.google.com",
success: function(data) { alert(data); },
error: function(req, err) { alert(err);}
});
});
</script>
You can't directly do this with javascript but there are alternative ways to do it if you are using a server.
javascript part:
<script type="text/javascript" src="js/jquery-1.7.2.js"></script>
<script type="text/javascript">
$(document).ready(function(){
$.ajax({
url: "http://yourserver/geturl.php?url=http://www.google.com",
// or url: "http://yourserver/geturl.aspx?url=http://www.google.com",
success: function(data) {
alert(data);
},
error: function(req, err) {
alert(err);
}
});
});
</script>
the server part (for geturl.php):
<?php
echo file_get_contents($_GET["url"]);
?>
or the same logic with asp.net.
the key part is here, that the code runs the javascript and php(aspx) should be on the same domain.

I'm trying to handle callback of jsonp request, but callback function is not run.
$(document).ready(function() {
$.ajax({
url: 'https://storage-testnet.shiftproject.com/peers?callback=?',
type: "GET",
dataType: 'jsonp',
jsonpCallback: 'peersData',
complete: peersData

var peersData = function (data) {
if(!data){
console.log("Error, can't retrieve data");
} else {
console.log(data)
}
}
}
Is there some mistake?
Your data is not wrapped in a pad eg. the following
<script type="text/javascript" language="javascript" src="https://code.jquery.com/jquery-3.3.1.js"></script>
<script type="text/javascript">
//credit https://www.sitepoint.com/jsonp-examples/
function jsonCallback(json) {
console.log(json);
}
$.ajax({
url: "http://run.plnkr.co/plunks/v8xyYN64V4nqCshgjKms/data-2.json",
dataType: "jsonp"
});
</script>

controller.php -simple php file that return json array:
<?php
$arr=array ('a'=>1,'b'=>2,'c'=>3,'d'=>4,'e'=>5);
echo json_encode($arr);
?>
Thanks
The form has a default action with a type="submit" button, which is submitting, so you'll need to stop that from happening by adding return false or event.preventDefault() , like this:
$(document).ready(function() {
$('#submit-html').click(function(e) {
$.ajax({
url: 'controller.php',
type: 'POST',
dataType:'json',
success: function(data) {
alert("response begin");
alert(data);
$.each(data, function (i, elem) {
$('#array-values').append('<div>'+elem+'</div>');
});
}
});
return false;
//or e.preventDefault();
});
});
Without this, the form is submitting as it normally would with no JavaScript, leaving the page. So effectively it's doing a refresh, instead of AJAX submitting your form (which doesn't have time to complete...because you left :)
An element of type=submit inside a <form> will perform the form request when clicked on.
You need to abort the default behavior by running event.preventDefault() inside the click callback.
My guess is that the form is submitting and refreshing the page before the ajax has a chance to respond.
Try putting return false; at the end of the click handler.
$('#submit-html').click(function() {
$.ajax({
url: 'controller.php',
type: 'POST',
dataType: 'json',
success: function(data) {
alert("response begin");
alert(data);
$.each(data, function(i, elem) {
$('#array-values').append('<div>' + elem + '</div>');
});
}
});
return false;
});
Of course you'll have the same issue if the user hits Enter in one of the fields. Unless you're preventing the Enter key from submitting the form, you may want to the handle the event using the submit() handler.
$('#parse-form').submit(function() {
$.ajax({
url: 'controller.php',
type: 'POST',
dataType: 'json',
success: function(data) {
alert("response begin");
alert(data);
$.each(data, function(i, elem) {
$('#array-values').append('<div>' + elem + '</div>');
});
}
});
return false;
});
Try using submit() http://api.jquery.com/submit/ , this should work with keyboard events as well as clicks. You can use serialize() to get any form data into the ajax objects data variable.
