从PHP jQuery的Ajax响应变量
问题描述：
我有一个简单的问题，但一直没能找到我所需要的精确解。我如何使用jQuery的$就调用一个PHP文件，只是回声两个PHP变量，并将其保存到JavaScript变量的反应呢？
I've got a simple question, but haven't been able to find the exact solution I need. How can I use a jQuery $.ajax to call a PHP file that just echos two PHP variables, and save them to javascript variables in the response?
答
你会做这样的事情：
$.getJSON('ajax_responder.php', function(data){
window.var1 = data.var1;
window.var2 = data.var2;
});
，然后在ajax_responder.php
and then in ajax_responder.php
<?php
header('Content-type: application/json');
$var1 = 'foo';
$var2 = 'bar';
$data = array(
'var1' => $var1,
'var2' => $var2
);
echo(json_encode($data));
?>
