JQuery中serialize()用法实例分析_jquery

一、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 </p> <p>//使用:$("#form1").serialize();</p> <p>上面则获取不到值。<br /> <br /> 二、JQuery中serialize()实例<br /> <br /> 1、ajax serialize()<br /> 代码如下:$.ajax({<br /> type: "POST",<br /> dataType: "json",<br /> url:ajaxCallBack,<br /> data:$('#myForm').serialize(),// 要提交表单的ID<br /> success: function(msg){<br /> alert(msg);<br /> }<br /> });</p> <p>2、serialize() 序列化表单实例<br /> 代码如下:</ script><br /> </pre>输出a=1&b=2&c=3<br /> <br /> 2、serializeArray<br /> <br /> serializeArray方法是将一个表单当中的各个字段序列化成一个数组<br /> serializeArray方法的jquery定义<br /> 代码如下:serializeArray: function() {<br /> /// <summary><br /> /// Serializes all forms and form elements but returns a JSON data structure.<br /> /// </summary><br /> /// <returns type="String">A JSON data structure representing the serialized items.</returns></p> <p>return this.map(function(){<br /> return this.elements ? jQuery.makeArray(this.elements) : this;<br /> })<br /> .filter(function(){<br /> return this.name && !this.disabled &&<br /> (this.checked || /select|textarea/i.test(this.nodeName) ||<br /> /text|hidden|password|search/i.test(this.type));<br /> })<br /> .map(function(i, elem){<br /> var val = jQuery(this).val();<br /> return val == null ? null :<br /> jQuery.isArray(val) ?<br /> jQuery.map( val, function(val, i){<br /> return {name: elem.name, value: val};<br /> }) :<br /> {name: elem.name, value: val};<br /> }).get();<br /> }</p> <p>serializeArray数据例子：<br /> 代码如下:[ { <br /> name : username, <br /> value : 中国 <br /> }, { <br /> name : password, <br /> value : xxx <br /> }]</p> <p>希望本文所述对大家的jQuery程序设计有所帮助。 </p><p><script type="text/javascript" src="https://jss.51dongshi.net/pcwz/dysph.js"></script></div> <div class="downbox clearfix"> <div class="ico"><img src="https://js.51dongshi.net/tpl/pc2/images/document.png" alt="文档"></div> <div class="txt"> <h4>JQuery中serialize()用法实例分析_jquery</h4> <div class="co">JQuery中serialize()用法实例分析_jquery:本文实例讲述了JQuery中serialize()用法。分享给大家供大家参考。具体分析如下： 一、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</div> <div class="tj"><b>推荐度：</b><div class="tj_stars_list"><i class="tj_stars tj_05"></i></div></div> </div> <div class="btn"> <a href="javascript:;" class="html2word" data-model="article" data-id="avvdgr" title="文档下载"> <b>点击下载本文</b> <span>文档为doc格式</span> </a> </div> </div> <script>keji_detail_ga('article_content_bottom');</script> <div class="tvideo_tag"> 标签： <a href="/tlist-9367/">使用</a> <a href="/tlist-11147/">用法</a> <a href="/tlist-297856/">实例</a> </div> <div class="tvideo_box tvideo_box_tab"> <div class="hd"> <ul><li class="on">热门焦点</li><script>keji_detail_ga('hot_jiaodian_tab_title');</script></ul> </div> <div class="bd"> <ul class="ult_jpic clearfix"> <script>get_hot_jiaodian_content('wz_hot_jiaodian',33,'hot',1);</script> </ul> </div> </div> </div> <!--中间文章 end--> <!--右侧专题 star--> <div class="ult_zt"> <script>keji_detail_ga('article_right_top');</script> <div class="ult_ztbox"> <h4>最新推荐</h4> <ul class="tvideo_r_a clearfix"> <script>get_detail_right('wz_right_new',33,'')</script> </ul> </div> <script>keji_detail_ga('article_right_middle');</script> <div class="ult_ztbox"> <h4>猜你喜欢</h4> <ul class="telist_rb clearfix"> <script>get_detail_right('wz_right_love',33,'')</script> </ul> </div> <script>keji_detail_ga('article_right_new_bottom');</script> <div class="ult_ztbox"> <h4>热门推荐</h4> <ul class="tvideo_r_b clearfix"> <script>get_detail_right('wz_right_hot',33,'')</script> </ul> </div> <script>keji_detail_ga('article_right_bottom');</script> </div> <!--右侧专题 end--> <div style="display:none"><a href="https://www.51dongshi.net/wzztf/av/avvdgr/">专题</a> </div> </div> </div> <script src="https://js.51dongshi.net/plug/qrcode/qrcode.min.js"></script> <script src="https://js.51dongshi.net/js/share.js" charset="UTF-8"></script> <script type="text/javascript" src="https://js.51dongshi.net/tpl/pc2/js/waypoints.min.js"></script> <script type="text/javascript" src="https://js.51dongshi.net/tpl/pc2/js/icon_step.js"></script> <style> #qrcode{padding: 15px;background: #fff;} </style> <div id="qrcode" style="display: none"></div> <script>new QRCode(document.getElementById("qrcode"), "https://m.51dongshi.net/eedfavvdgr.html");</script> <iframe src="https://hits.51dongshi.net/?biao=ho_article&id=977241" border="0" frameborder="0" style="width: 0px;
