jquery中serialize方法怎么用

serialize()定义和用法：

serialize()方法通过序列化表单值，创建标准的URL编码文本字符串，它的操作对象是代表表单元素集合的jQuery 对象。你可以选择一个或多个表单元素（比如input或文本框），或者 form 元素本身。序列化的值可在生成 AJAX 请求时用于 URL 查询字符串中。

语法：

$(selector).serialize()

详细说明

1、.serialize() 方法创建以标准 URL 编码表示的文本字符串。它的操作对象是代表表单元素集合的 jQuery 对象。

2、.serialize() 方法可以操作已选取个别表单元素的 jQuery 对象，比如 , 以及 <select>。不过，选择 <form> 标签本身进行序列化一般更容易些</p><p>3、只会将”成功的控件“序列化为字符串。如果不使用按钮来提交表单，则不对提交按钮的值序列化。如果要表单元素的值包含到序列字符串中，元素必须使用 name 属性。</p><p>4、form里面的name不能够用 Js、jquery里的关键字。</p><p>例如：length</p><p>代码如下:</p><div class="code" style="position:relative; padding:0px; margin:0px;"><pre class='brush:php;toolbar:false;'><form id="form1"> <input name="length" type="text" value="pipi" /> <input name="blog" type="text" value="blue submarine" /> </form> //使用:$("#form1").serialize();</pre><div class="contentsignin">登录后复制</div></div><p>上面则获取不到值。</p><p><strong>JQuery中serialize()实例</strong></p><p>1、ajax serialize()</p><p>代码如下:</p><div class="code" style="position:relative; padding:0px; margin:0px;"><pre class='brush:php;toolbar:false;'>$.ajax({ type: "POST", dataType: "json", url:ajaxCallBack, data:$(&#39;#myForm&#39;).serialize(),// 要提交表单的ID success: function(msg){ alert(msg); } });</pre><div class="contentsignin">登录后复制</div></div><p>2、serialize() 序列化表单实例</p><p>代码如下:</p><div class="code" style="position:relative; padding:0px; margin:0px;"><pre class='brush:php;toolbar:false;'><script src="https://cdn.staticfile.org/jquery/1.10.2/jquery.min.js"></script> <script> $(function(){ $("#submit").click(function(){ alert($("#myForm").serialize()); }); }); </script> <form id="myForm"> 昵称 <input type="text" name="username" value="admin" /><br /> 密码 <input type="password" name="password" value="admin123" /><br /> <input type="button" id="submit" value="序列化表单" /> </form></pre><div class="contentsignin">登录后复制</div></div><p>点击按钮之后弹出：</p> <p>username=admin&password=admin123</p> <p>相关视频教程推荐：<a href="https://www.php.cn/course/list/19.html" target="_blank" textvalue="jQuery教程">jQuery视频教程</a></p><p>以上是jquery中serialize方法怎么用的详细内容。更多信息请关注PHP中文网其他相关文章！</p> </div> </div> <div class="wzconShengming_sp"> <div class="bzsmdiv_sp">本站声明</div> <div>本文内容由网友自发贡献，版权归原作者所有，本站不承担相应法律责任。如您发现有涉嫌抄袭侵权的内容，请联系admin@php.cn</div> </div> </div> <ins class="adsbygoogle" style="display:block" data-ad-format="autorelaxed" data-ad-client="ca-pub-5902227090019525" data-ad-slot="2507867629"></ins> <script> (adsbygoogle = window.adsbygoogle || []).push({});
