php+ajax试用

Jun 23, 2016 pm 02:34 PM

 

1.首先在页面中引用js.rar文件

2. 使用jQuery.ajax( [options]) 方法:说明

通过 HTTP 请求加载远程数据。

 

jQuery 底层 AJAX 实现。简单易用的高层实现见 $.get, $.post 等。$.ajax() 返回其创建的 XMLHttpRequest 对象。大多数情况下你无需直接操作该对象,但特殊情况下可用于手动终止请求。

 

$.ajax() 只有一个参数:参数 key/value 对象,包含各配置及回调函数信息。详细参数选项见下。

 

注意: 如果你指定了 dataType 选项,请确保服务器返回正确的 MIME 信息,(如 xml 返回 "text/xml")。错误的 MIME 类型可能导致不可预知的错误。见 Specifying the Data Type for AJAX Requests 。

 

注意:如果dataType设置为"script",那么在远程请求时(不在同一个域下),所有POST请求都将转为GET请求。(因为将使用DOM的script标签来加载)

 

jQuery 1.2 中,您可以跨域加载 JSON 数据,使用时需将数据类型设置为 JSONP。使用 JSONP 形式调用函数时,如 "myurl?callback=?" jQuery 将自动替换 ? 为正确的函数名,以执行回调函数。数据类型设置为 "jsonp" 时,jQuery 将自动调用回调函数。

 

3.例子:不经过表单提交添加信息

Jquery代码:

function sub()

    {

    $.ajax(

           {

 

              "type":"POST",///////提交方式

              "url":"address.php?job=addother&id=$rsdb[id]&act=add",//////提交的Url,可以只是一个url,参数写在data中,也可以在这里写参数

              "data":{////参数格式:参数名:值如果为数组,jQuery 将自动为不同值对应同一个名称。如 {foo:["bar1", "bar2"]} 转换为'&foo=bar1&foo=bar2'。

                  "username":$('#username').val(),

                  "province_id":$('#province_id').val(),

                  "city_id":$('#city_id').val(),

                  "street":$('#street').val(),

                  "zode":$('#zode').val(),

                  "telphone":$('#telphone').val(),

                  "mobilephone":$('#mobilephone').val()

              },

              "dataType":"json",//预期服务器返回的数据类型。如果不指定,jQuery 将自动根据 HTTP 包 MIME 信息返回 responseXML 或 responseText,并作为回调函数参数传递,可用值:

"xml": 返回 XML 文档,可用 jQuery 处理。

"html": 返回纯文本 HTML 信息;包含的script标签会在插入dom时执行。

"script": 返回纯文本 JavaScript 代码。不会自动缓存结果。除非设置了"cache"参数。'''注意:'''在远程请求时(不在同一个域下),所有POST请求都将转为GET请求。(因为将使用DOM的script标签来加载)

"json": 返回 JSON 数据 。

"jsonp": JSONP 格式。使用 JSONP 形式调用函数时,如 "myurl?callback=?" jQuery 将自动替换 ? 为正确的函数名,以执行回调函数。

"text": 返回纯文本字符串

              "cache":false,

               success:function(data){//请求成功后的回调函数。参数:由服务器返回,并根据dataType参数进行处理后的数据;描述状态的字符串

                  if(!data.success)

                     {

                         alert(data.data.message);  

                     }

                  else{

                  $('#hiddiv').hide();

                  $('#hiddiv').empty();

                  $('#adlist').load("address.php?job=adlist");

                  }

                 

              }

             

             

           }

       );

 

    }

Html:

           align="center">

Explain secure password hashing in PHP (e.g., password_hash, password_verify). Why not use MD5 or SHA1? Explain secure password hashing in PHP (e.g., password_hash, password_verify). Why not use MD5 or SHA1? Apr 17, 2025 am 12:06 AM

In PHP, password_hash and password_verify functions should be used to implement secure password hashing, and MD5 or SHA1 should not be used. 1) password_hash generates a hash containing salt values ​​to enhance security. 2) Password_verify verify password and ensure security by comparing hash values. 3) MD5 and SHA1 are vulnerable and lack salt values, and are not suitable for modern password security.
