javascript - 使用 Ajax POST PHP 和 javascript 数据

Question

如果这是一个重复的问题，我深表歉意，但我在其他地方找不到答案。

我有一个页面，用户可以在其中查看所有提交的内容，每个提交内容都位于单独的一行中。有一个“X”，当用户单击它时，我希望在数据库中删除该行。

这是我的函数(jQuery)，当用户单击“X”时触发

$(document).ready(function(){
    $(".delete").click(function(e){
        var id = e.target.id;
        $("#"+id + "_row").hide('slow');
        //Need to POST the id variable to PHP file.
    });
});

如何将 ID 变量发布到 php 文件，然后在数据库上运行 mySQL 查询？

Answer 1

$(document).ready(function(){
    $(".delete").click(function(e){
        var id = e.target.id;
        $("#"+id + "_row").hide('slow');
        $.ajax({
            url: "path/to/php/file",
            dataType: "json",
            method: "POST",
            data: { target: e.target.id },
            success: function(data) {
                // do something with the data passed back by the PHP script.
            }
    });
});

参数:

url: self explanatory

dataType: the kind of data you're expecting to get from the PHP script

method: http method which you'll use for your request

data: data you'll be passing to the PHP, since we're using POST in this case. If you were using GET, you can set variables in the "url:" field just like you would on any other url.

success: what happens when the request succeeds.
