动态创建html元素的几种方法

可以通过以下几种方式动态创建html元素:
1、使用jQuery创建元素的语法
2、把动态内容存放到数组中,再遍历数组动态创建html元素
3、使用模版

 

□ 使用jQuery动态创建元素追加到jQuery对象上。

   1:  <meta http-equiv="Content-Type" content="text/html; charset=utf-8"/>
   2:      <title></title>
   3:      <script src="Scripts/jquery-1.10.2.js"></script>
   4:      <script type="text/javascript">
   5:          $(function() {
   6:              $(‘<input />‘, {
   7:                  id: ‘cbx‘,
   8:                  name: ‘cbx‘,
   9:                  type: ‘checkbox‘,
  10:                  checked: ‘checked‘,
  11:                  click: function() {
  12:                      alert("点我了~~");
  13:                  }
  14:              }).appendTo($(‘#wrap‘));
  15:          });
  16:      </script>
  17:  </head>
  18:  <body>
  19:      <div id="wrap"></div>
  20:  </body>

 

□ 先把内容放到数组中,然后遍历数组拼接成html

   1:  <head>
   2:  <meta http-equiv="Content-Type" content="text/html; charset=utf-8"/>
   3:      <title></title>
   4:      <script src="Scripts/jquery-1.10.2.js"></script>
   5:      <style type="text/css">
   6:          table {
   7:              border: solid 1px red;
   8:              border-collapse: collapse;
   9:          }
  10:   
  11:          td {
  12:              border: solid 1px red;
  13:          }
  14:      </style>
  15:      <script type="text/javascript">
  16:          $(function () {
  17:              var data = ["a", "b", "c", "d"];
  18:              var html = ‘‘;
  19:              for (var i = 0; i < data.length; i ++) {
  20:                  html += "<td>" + data[i] + "</td>";
  21:              }
  22:              $("#row").append(html);
  23:          });
  24:      </script>
  25:  </head>
  26:  <body>
  27:      <table>
  28:          <tr id="row"></tr>
  29:      </table>
  30:  </body>
  31:  </html>
  32:   

 

□ 使用模版生成html

   1:  <meta http-equiv="Content-Type" content="text/html; charset=utf-8"/>
   2:      <title></title>
   3:      <script src="Scripts/jquery-1.10.2.js"></script>
   4:      <script type="text/javascript">
   5:          $(function () {
   6:             var a = buildHTML("a", "我是由模版生成的", {
   7:                  id: "myLink",
   8:                  href: "http://www.baidu.com"
   9:             });
  10:   
  11:             $(‘#wrap1‘).append(a);
  12:   
  13:              var input = buildHTML("input", {
  14:                  id: "myInput",
  15:                  type: "text",
  16:                  value: "我也是由模版生成的~~"
  17:              });
  18:   
  19:              $(‘#wrap2‘).append(input);
  20:          });
  21:   
  22:          buildHTML = function(tag, html, attrs) {
  23:              // you can skip html param
  24:              if (typeof (html) != ‘string‘) {
  25:                  attrs = html;
  26:                  html = null;
  27:              }
  28:              var h = ‘<‘ + tag;
  29:              for (attr in attrs) {
  30:                  if (attrs[attr] === false) continue;
  31:                  h += ‘ ‘ + attr + ‘="‘ + attrs[attr] + ‘"‘;
  32:              }
  33:              return h += html ? ">" + html + "</" + tag + ">" : "/>";
  34:          };
  35:      </script>
  36:  </head>
  37:  <body>
  38:      <div id="wrap1"></div>
  39:      <div id="wrap2"></div>
  40:  </body>
  41:
