ExtJS基础知识总结：自定义日历和ComboBox控件(二)

概述

　　1、ExtJS 5不支持日期选择框中只选择年月，为了满足ExtJs5可以实现选择年月的功能，查询网上资料，整理出来了相应的处理方式，最终实现的效果如下图：



　　2、ExtJS 控件丰富，如果需要实现下拉列表控件ComboBox中含有Check样式的皮肤，只需要在ComboBox控件中监听相应的下拉事件和选择事件即可。实现的效果如下：

　　


日历控显示年月的实现方式

1、编写ext-extendmonth.js，代码内容如下

Ext.define('Ext.form.field.Month', {
extend: 'Ext.form.field.Date',
alias: 'widget.monthfield',
requires: ['Ext.picker.Month'],
alternateClassName: ['Ext.form.MonthField', 'Ext.form.Month'],
selectMonth: null,
createPicker: function () {
var me = this,
format = Ext.String.format,
pickerConfig;
pickerConfig = {
pickerField: me,
ownerCmp: me,
renderTo: document.body,
floating: true,
hidden: true,
focusOnShow: true,
minDate: me.minValue,
maxDate: me.maxValue,
disabledDatesRE: me.disabledDatesRE,
disabledDatesText: me.disabledDatesText,
disabledDays: me.disabledDays,
disabledDaysText: me.disabledDaysText,
format: me.format,
showToday: me.showToday,
startDay: me.startDay,
minText: format(me.minText, me.formatDate(me.minValue)),
maxText: format(me.maxText, me.formatDate(me.maxValue)),
listeners: {
select: { scope: me, fn: me.onSelect },
monthdblclick: { scope: me, fn: me.onOKClick },
yeardblclick: { scope: me, fn: me.onOKClick },
OkClick: { scope: me, fn: me.onOKClick },
CancelClick: { scope: me, fn: me.onCancelClick }
},
keyNavConfig: {
esc: function () {
me.collapse();
}
}
};
if (Ext.isChrome) {
me.originalCollapse = me.collapse;
pickerConfig.listeners.boxready = {
fn: function () {
this.picker.el.on({
mousedown: function () {
this.collapse = Ext.emptyFn;
},
mouseup: function () {
this.collapse = this.originalCollapse;
},
scope: this
});
},
scope: me,
single: true
}
}
return Ext.create('Ext.picker.Month', pickerConfig);
},
onCancelClick: function () {
var me = this;
me.selectMonth = null;
me.collapse();
},
onOKClick: function () {
var me = this;
if (me.selectMonth) {
me.setValue(me.selectMonth);
me.fireEvent('select', me, me.selectMonth);

}
me.collapse();
},
onSelect: function (m, d) {
var me = this;
me.selectMonth = new Date((d[0] + 1) + '/1/' + d[1]);
}
});

2、引入ext-extendmonth.js以及修改预显示控件 xtype: 'monthfield' 属性值

//头部菜单栏
var proctoolbarText = Ext.create('Ext.toolbar.Toolbar', {
renderTo: 'ReportData',
items: [{
xtype: 'monthfield',
id: 'CountData',
width: 180,
labelWidth: 30,
format: 'Y-m',
fieldLabel: '日期',
emptyText: '请输入开始时间',
editable: false,        //不可编辑
value: Ext.get("countDate").getValue()
}]});

下拉列表控件ComboBox中含有Check实现

1、自定义JS控件Checktool

var Checktool=Ext.create('Ext.form.field.ComboBox',{
name : 'cmb',
fieldLabel : '人员',
margin:'2 0 2 0',
labelWidth : 135,
labelAlign : 'right',
editable : false,
allowBlank : false,
multiSelect : true,
store : {
fields : ['personId', 'personName'],
data : [
{'personId':'0',personName:'张三'},
{'personId':'1',personName:'李四'},
{'personId':'2',personName:'王五'},
{'personId':'3',personName:'小名'}
]
},
listConfig : {
itemTpl : Ext.create('Ext.XTemplate','<input type=checkbox>{[values.personName]}'),
onItemSelect : function(record) {
var node = this.getNode(record);
if (node) {
Ext.fly(node).addCls(this.selectedItemCls);
var checkboxs = node.getElementsByTagName("input");
if (checkboxs != null)
var checkbox = checkboxs[0];
checkbox.checked = true;
}
},
listeners : {
itemclick : function(view, record, item, index, e, eOpts) {
var isSelected = view.isSelected(item);
var checkboxs = item.getElementsByTagName("input");
if (checkboxs != null) {
var checkbox = checkboxs[0];
if (!isSelected) {
checkbox.checked = true;
} else {
checkbox.checked = false;
}
}
}
}
},
queryMode : 'local',
displayField : 'personName',
valueField : 'personId',
});

2、ExtJS引用控件即可

//头部菜单栏
var proctoolbarText = Ext.create('Ext.toolbar.Toolbar', {
renderTo: 'ReportData',
items: [
Checktool
]});
