1.获取input值 的6种方法：
1. <!doctype html>
2. <html>
3. <head>
4. <meta http-equiv="Content-Type" content="text/html; charset=utf-8">
5. <title>测试页面</title>
6. <script type="text/javascript" src="jquery.js"></script>
7. </head>
8. <body>
9. <div id="gjdiv" class="gjc">
10. <input type="hidden" id="title" name="gj" value="113"/>
11. <input type="hidden" id="brief" name="gj" value="df"/>
12. <input type="hidden" id="content" name="gj" value="sg"/>
13. </div>
14.
15. <script>
16. $(document).ready(function(){
17. var param0 = $("input[name='gj']").val();
18. console.log("param0:"+param0);
19.
20. var param1 = $(".gjc input[name='gj']").val();
21. console.log("param1:"+param1);
22.
23. var param2 = $("#gjdiv input[name='gj']").val();
24. console.log("param2:"+param2);
25.
26. var param3 = $("div input[name='gj']").val();
27. console.log("param3:"+param3);
28.
29. var param4 = $("#gjdiv>input[name='gj']").val();
30. console.log("param4:"+param4);
31.
32. var param5 = $("#gjdiv :input[name='gj']").val();
33. console.log("param5:"+param5);
34.
35. console.log("stringify():"+JSON.stringify(param0));
36. //console.log(JSON.parse(param));
37.
38. })
39.
40. </script>
41. </body>
42. </html>
结果：
获取的都是第一个input的值。
2.将input值序列化：
1. <!doctype html>
2. <html>
3. <head>
4. <meta http-equiv="Content-Type" cnotallow="text/html; charset=utf-8">
5. <title>测试页面</title>
6. <script type="text/javascript" src="jquery.js"></script>
7. </head>
8. <body>
9. <div id="gjdiv" class="gjc">
10. <input type="hidden" id="title" name="gj" value="113"/>
11. <input type="hidden" id="brief" name="gj" value="df"/>
12. <input type="hidden" id="content" name="gj" value="sg"/>
13. </div>
14.
15. <script>
16. $(document).ready(function(){
17. var param0 = $("input[name='gj']").serialize();
18. console.log("param0:"+param0);
19.
20. var param1 = $(".gjc input[name='gj']").serialize();
21. console.log("param1:"+param1);
22.
23. var param2 = $("#gjdiv input[name='gj']").serialize();
24. console.log("param2:"+param2);
25.
26. var param3 = $("div input[name='gj']").serialize();
27. console.log("param3:"+param3);
28.
29. var param4 = $("#gjdiv>input[name='gj']").serialize();
30. console.log("param4:"+param4);
31.
32. var param5 = $("#gjdiv :input[name='gj']").serialize();
33. console.log("param5:"+param5);
34.
35. console.log("stringify():"+JSON.stringify(param0));
36. //console.log(JSON.parse(param));
37.
38. })
39.
40. </script>
41. </body>
42. </html>
结果：
