如何在index.php页面上的ajax中调用更新文件

Question

update.php页面

window.onbeforeunload

想在function myfoo(){ $.ajax({ url: "update.php", dataType: 'json', data: {id: 1}, success: function (r) {} }); } window.onbeforeunload = function(){ myfoo(); return 'Are you sure you want to leave?'; }; 上的index.php页面上使用update.php文件

在这里使用ajax

Cursor cursor = db.rawQuery("SELECT * FROM videoplayer where " + KEY_VIDEO_TAG + " like '%"+ searchText +"%'", null);

Answer 1

1）您没有发送任何数据，例如行包

2）ajax未定义类型：'post'，但您的访问价值是邮寄。如果你没有定义类型意味着ajax将使用默认的get方法。

$.ajax({
            url: "update.php",
            type:'post',
            dataType: 'json',
            data: {id: 1,bags:bags}, // bags collection value what your goging to send to server 
            success: function (r) {}
});

工作代码只需改变一件事。谢谢@JYoThI https://stackoverflow.com/users/5933698/jyothi

$.ajax({
            url: "update.php",
            type:'post',
            dataType: 'json',
            data: {
                on_timeout: 1 // i just add this line
            },
 // bags collection value what your goging to send to server 
            success: function (r) {}
});
