Вот функция
function call(a) {
alert(a);
}
function getJSONP(url, callback) {
// Create a unique callback name just for this request
var cbnum = "cb" + getJSONP.counter++; // Increment counter each time
var cbname = "getJSONP." + cbnum; // As a property of this function
if (url.indexOf("?") === -1) // URL doesn't already have a query section
url += "?jsonp=" + cbname; // add parameter as the query section
else // Otherwise,
url += "&jsonp=" + cbname; // add it as a new parameter.
var script = document.createElement("script");
getJSONP[cbnum] = function(response) {
try {
callback(response); // Handle the response data
}
finally { // Even if callback or response threw an error
delete getJSONP[cbnum]; // Delete this function
script.parentNode.removeChild(script); // Remove script
}
};
script.src = url; // Set script url
document.body.appendChild(script); // Add it to the document
}
getJSONP.counter = 0; // A counter we use to create unique callback names
getJSONP( "ph.php", call);
getJSONP( "http://my/ph.php", call);
а вот ph.php
<?php
echo 5;
Всё правильно, но почему никакой реакции не происходит? Или php по другому доложен возвращать?
