js -ajax 学习

2、ajax

1）跨域

$.ajax({
        type : "get",
        data : "data_xName=" + data_xName ,
        url : "http://222.73.x.x/qing/11.php",
        dataType : "jsonp",
//        jsonp: 'jsoncallback',
        success : function(data)
         {
             alert(data);
         }

});

<?php

header('Access-Control-Allow-Origin:*');

$aa="aaa";

//echo $_REQUEST['callback'] . '(' .$aa. ')';
//echo $_REQUEST['callback'] . '("testfsfsdf")';
echo $_REQUEST['callback'] . '(' .json_encode($aa). ')';

?>
        
        
        
2）不跨域
     $.ajax({
        type : "get",
        data : "data_xName=" + data_xName ,
        url : "/test/",

success : function(data)
         {
             alert(data);
         }

});

def test_version(request):
    name = request.GET.get('data_xName')
    return HttpResponse(name)
