JSP代码如下：



<form>

	<div class="x_input">

		<p><input name="userCode" value="" type="text" id="user.USER_CODE" style="font-size:12px; font-family:Arial;"  />

		</p>

	  <p style="margin-top:4px;"><input name="password" value="" type="password" id="user.PASSWORD" style="font-size:12px; font-family:Arial;" >

			<span style="margin-left:12px;">

				<input id="SubId" type="button" onclick="login();" onkeypress="login();" style="width: 67px; height: 22px; background: url(images/x_login.png); border: 0px;"/>

			</span>	

	  </p>

	</div>

</form>

javascript函数如下：



<script type="text/javascript">

function login(){

  var userCode=document.all.userCode.value;

  var password=document.all.password.value;

  Ext.Ajax.request({

        method:'POST',       

        url:'loginUser', 

        params:{"user.USER_CODE":userCode,"user.PASSWORD":password},

        success:function(response, options){   

         var respText = Ext.util.JSON.decode(response.responseText);     

         if(respText.msg=="登录成功!"){

            var data = respText.data;

                var userName=respText.userName;

                var userId=respText.userId;

                var topicNames = new Array(); 

                var topicIds = new Array(); 

                if (typeof(data) != "undefined" && data.length > 0) 

		       {

      			 for(var i=0;i<data.length;i++)

      			 {

			        	topicNames.push(data[i]["topic_name"]);

			        	topicIds.push(data[i]["topic_id"]);			        	

      			  }

		       }

                    

    		 var f=document.createElement("form");

                f.action=rootPath+"/IasManager.jsp";

                f.method="post";//指定为post

                f.innerHTML="<input type='hidden' name='userName' value='"+userName+"'/>;"+

                "<input type='hidden' name='userId' value='"+userId+"'/>;"+

                "<input type='hidden' name='topicNames' value='"+topicNames+"'/>;"+

                "<input type='hidden' name='topicIds' value='"+topicIds+"'/>";

                document.appendChild(f);

                 f.submit();

                 

         } else{

         	 Ext.MessageBox.minWidth = 150;

             Ext.Msg.alert('提示',respText.msg);

         }    

       },

        failure:function(response, options){  

         Ext.MessageBox.minWidth = 120;   

         Ext.Msg.alert('提示','操作失败。');

         }

       

      });

   }

    

</script>
