我正在制作一个自定义日期时间过滤器,因为 Ext 的日期时间过滤器不是很好。我有一个日期时间字段:一个具有价值的字段容器中的日期字段和时间字段......它工作正常。
Ext.ux.grid.filter.Filter
我像日期过滤器一样扩展并构建我的过滤器。
fieldCfg = Ext.apply(me.fieldOpts, {
xtype: 'datetimefield',
overflowX: 'visible',
format: me.format,
});
fields = {};
for (i = 0, len = me.menuItems.length; i < len; i++) {
item = me.menuItems[i];
if (item !== '-') {
cfg = {
itemId: 'range-' + item,
text: me[item + 'Text'],
menu: Ext.create('Ext.menu.Menu', {
plain: true,
items: [
Ext.apply(fieldCfg, {
itemId: item,
margin: '2 10 2 2',
overflowX: 'visible'
})
],
}),
listeners: {
scope: me,
checkchange: me.onCheckChange,
render: function (t){
var dtf = t.menu.items.items[0];
var df = dtf.getDateField();
var tf = dtf.getTimeField();
df.on("select", me.selectDateEvent, me)
tf.on("select", me.selectDateEvent, me)
},
}
};
item = me.fields[item] = Ext.create('Ext.menu.CheckItem', cfg);
}
me.menu.add(item);
}
me.values = {};
这是使过滤器值的函数:
selectDateEvent: function (t) {
if(t.ownerCt.getValue() !== undefined){
var date = Ext.Date.format(t.ownerCt.getValue(), format);
this.values[t.ownerCt.itemId] = date;
this.fireEvent('update', this);
this.onMenuSelect(t.ownerCt, date);
}
},
这是其他处理程序的代码:
onCheckChange: function(item, checked) {
var me = this,
picker = item.menu.items.items[0],
itemId = picker.itemId,
values = me.values;
if (checked) {
values[itemId] = picker.getValue();
} else {
delete values[itemId]
}
me.setActive(me.isActivatable());
me.fireEvent('update', me);
}
onMenuSelect: function(picker, date) {
var fields = this.fields,
field = this.fields[picker.itemId];
field.setChecked(true);
if (field == fields.on) {
fields.before.setChecked(false, true);
fields.after.setChecked(false, true);
} else {
fields.on.setChecked(false, true);
if (field == fields.after && this.getFieldValue('before') < date) {
fields.before.setChecked(false, true);
} else if (field == fields.before && this.getFieldValue('after') > date) {
fields.after.setChecked(false, true);
}
}
this.fireEvent('update', this);
picker.up('menu').hide();
}
但它不过滤网格的数据。我怎样才能让它工作?我做错了什么?
