$.ajax({ type: "post", url: "nodedo.php", data: $("#form1").serialize(), success: function(data) { layer.msg('添加成功', 2, 1); }, error: function(data) { layer.msg('添加失败', 2, 2); alert(data); } })
后台
$conn = mysql_connect("localhost","root","");$my_db = mysql_select_db("lyq",$conn); $account = $_POST['account']; $sql = "insert into salesman(account) values ('$account')"; $result = mysql_query($sql, $conn); $userInfo = mysql_fetch_assoc($result); echo json_encode($userInfo);
还有一种ajax提交
$.post( 'nodedo.php', { account:$("#account").val(), name:$("#name").val() // name:$("#name").val() }, function (data) { //回调函数 var myjson=''; eval('myjson=' + data + ';'); alert(data); } );
这种哪个地方不对?
回复讨论(解决方案)
alert(data)
看看才知道

看看才知道
data为空
哪里出问题了?
讲清楚症状,好查找问题。

我也不知道哪里出问题了,数据库没有变化,也没有返回值
你在哪里 alert(data) 的?

那你就跟踪下,看看有没能执行到数据库插入的语句,有的话,看看语句是什么,是不是能正确执行的。

获取返回值的时候

不会跟踪,嘿嘿
你在 nodedo.php 中
print_r($_POST);
你在 nodedo.php 中
print_r($_POST);
找到问题了,原来提交按钮必须放到form的外面
那倒不一定!
1、form onsubmit=’return false‘
2、input type=button value=’提交‘
都是不会表单提交的

You should care about DependencyInjection(DI) because it makes your code clearer and easier to maintain. 1) DI makes it more modular by decoupling classes, 2) improves the convenience of testing and code flexibility, 3) Use DI containers to manage complex dependencies, but pay attention to performance impact and circular dependencies, 4) The best practice is to rely on abstract interfaces to achieve loose coupling.

Select DependencyInjection (DI) for large applications, ServiceLocator is suitable for small projects or prototypes. 1) DI improves the testability and modularity of the code through constructor injection. 2) ServiceLocator obtains services through center registration, which is convenient but may lead to an increase in code coupling.

mPDF
mPDF is a PHP library that can generate PDF files from UTF-8 encoded HTML. The original author, Ian Back, wrote mPDF to output PDF files "on the fly" from his website and handle different languages. It is slower than original scripts like HTML2FPDF and produces larger files when using Unicode fonts, but supports CSS styles etc. and has a lot of enhancements. Supports almost all languages, including RTL (Arabic and Hebrew) and CJK (Chinese, Japanese and Korean). Supports nested block-level elements (such as P, DIV),
