簡介：

qtip是Jquery的一款提示插件，使用比較簡單，在Activiti工作流的流程追溯頁面使用到qtip插件。

使用步驟：

1、 下載qtip插件

http://qtip2.com/download

2、 下載的插件目錄

3、 一般情況下，將jquery.qtip.min.CSS和jquery.qtip.min.js放入項目中使用即可

4、 在頁面引入css和js

<link rel="stylesheet" href="${appName}/res/jquery.qtip.min.css"><script type="text/javascript" src="${appName}/res/jquery.qtip.min.js"></script>5、 需要加qtip提示的代碼片段(圖片映射代碼)

$(function(){	    $("area[type='userTask']").each(function (){	    	var nodeId=$(this).attr('id');	    	var PRocessInstanceId="${proc_inst_id_}";	    	$(this).qtip({	  			content:{	  				text:function (event,api){	  					$.Ajax({	  						url:'${appName}/workflow/workflowProcess/getActivityApprovalInfo.ajax',	  						data:{proc_inst_id_:processInstanceId,task_def_key_:nodeId}	  					})	  					.then(function(content) {	  						if(content.length>0){		  						var content_text="<table  border='1' width='260px;' height='50px;' style='text-align: center;font-size:12px;'>";		  						for(var i=0;i<content.length;i++){		  							content_text+="<tr><td width='115px;'>審批人:</td><td>"+content[i].assignee_+"</td></tr><tr><td>審批時間:</td><td>"+content[i].end_time_Disp+"</td></tr>"		  										  +"<tr><td>審批意見:</td><td>"+content[i].comment_message+"</td></tr>";		  						}		  						content_text+="</table>";		                        api.set('content.text', content_text);	  						}else{		                        api.set('content.text', "<div>暫無審批記錄</div>");	  						}	                    }, function(xhr, status, error) {	                        api.set('content.text', status + ': ' + error);	                    });	  					return '正在加載...';	  				}	  			},	  			position:{	  				target: 'mouse',	                adjust: { mouse: false }	  			}		    });	    });    });7、實現的效果
