- js 按钮不响应怎么解决
-
$(function() { $("#back").click(function() { //返回按钮事件 location.href = "welcome.html"; }); $("#search").click(function(){ var deptno = $("#deptno").val(); var res = query("select * from emp where deptno=" + deptno + ""); //组装SQL语句并执行查询 if(res != null){ //判断是否有返回值 //var res_2=query("select * from emp where deptno=" + deptno + "); sessionStorage['deptno'] = deptno; //deptno是要查看员工的部门的编号,把该编号放入sessionStorage, location.href = "get_dep_emp.html"; } }); }); </script> </head> <body> <div class="content"> <h2 class="title">查询部门员工</h2> <hr /> <table width="90%" align="center" class="tablelist"> <tr> <td width="45%" align="right">部门编号:</td> <td><input type="text" id="deptno" /></td> </tr> <td colspan="2" align="center"> <input type="submit" value=" 查询 " id="search" class="button" /> <input type="button" value=" 返回 " id="back" class="button" /> </td> </table> </div> </body>
但是查询和返回两个按钮都没有响应。。纯属菜鸟,请大神指点
解决方案
用chrome的console or Firebug看看有错没有先
解决方案二:
用$.document(ready){
}把你的代码给包了....
