日历组件部分代码：

在每个日期格中有一个下拉列表，这里面可以是在本地定义，也可以在数据库中查询，这里的处理是：下拉框中选择了就按照相对应的key来存，如果没有选择的话就按照空来处理，单击【确定】按钮后获取的结果格式如下：

",,,,,,[-06-01 1],[-06-02 2],,,,,,,,,,,,,,,[-06-17 1],[-06-18 2],[-06-19 3],,,,,,,[-06-26 2]"

转成字符串（传递参数识别的类型）：

if(dateArray != null && dateArray != "") {content = dateArray.join(',');//数组的话，不识别，要转换成字符串才可以}

引用日历组件的部分代码：

, {xtype: 'panel',style: 'margin-left:50;',layout: 'column',id: 'calendarArea',width: 700,height: 400,border: true,items: [{layout: 'form',width: '98%',height: '98%',items:[/** 这里放置日历控件 */myDate]}]}

注意：单击【确定】按钮后获取的值可以根据用户自己的需求来定义，代码是在3个for循环中修改。

var i = 0;for(; i < startingPos; ) {var tempId = "fruit"+i;d.setDate(d.getDate()+1);var fvalue = d.dateFormat(format);textEls[i].innerHTML = '<div align="center"><font size ="2" color = "#8B8378" >'+(++prevStart)+'</font>'+'<br></div>';cells[i].className = 'x-date-prevday';setCellClass(this, cells[i]);i = i + 1;}for(; i < days; ){var divId = "div"+i;var intDay = i - startingPos + 1;d.setDate(d.getDate()+1);var fvalue = d.dateFormat(format);var comboId = "combo"+fvalue+"-"+i;var clas = new boBox({store: classStore,id: comboId,width: 60,displayField: 'clasName',valueField: 'id',hiddenName: 'clasName1',typeAhead: true,triggerAction: 'all',forceSelection: true,selectOnFocus: true,mode: 'remote',editable: false});//classStore.on('load',function(){Ext.getCmp(comboId).setValue("0");});textEls[i].innerHTML = '<div align="center"><font size ="2">'+(intDay)+'</font>'+'<br><div id="'+divId+'"></div></div>';clas.render(divId);cells[i].className = 'x-date-active';setCellClass(this, cells[i]);clas.on('select',function(combo,record,index ){var str = "["+combo.id.substring(5,15)+" "+combo.getValue()+"]"dateArray[combo.id.substring(16,combo.id.length)] = str;}); i = i + 1; }var extraDays = 0;for(; i < 42; ) {var tempId = "fruit"+i;d.setDate(d.getDate()+1);var fvalue = d.dateFormat(format);textEls[i].innerHTML = '<div align="center"><font size ="2" color = "#8B8378">'+(++extraDays)+'</font>'+'<br></div>';cells[i].className = 'x-date-nextday';setCellClass(this, cells[i]);i = i + 1;}
