查詢資料時候等待效果

function waitSubmit(){try{$.blockUI({  //fadeIn: 700, //漸入式顯示  fadeOut: 700, //漸出式消失  timeout: 20000, //2 秒後消失  message: '<img width="32px" height="32px" src="/CNAS_LAS/images/load.gif" /><br/> 資料處理中，請稍候',  css: { border: '0',       backgroundColor: '#FFFFFF'  },  overlayCSS: { backgroundColor: '#FFFFFF' }});}catch(e){}}

下面為jsp提交時候的js

var doSave = function(){$('#transitionPersonName').val($('#transitionPerson_userId option:selected').text());$("#nextText").val($('#nextTransaction1 option:selected').text());mainForm.action = "${pageContext.request.contextPath}/approval/doSave.action?flag=${param.flag}";waitSubmit();mainForm.submit();}
