我在我的视图中有一个ExtJS网格,现在我想添加一些列过滤器... 我已经在网上搜索了,虽然我没有成功。 问题是如果我打开我可以排序等列的子菜单。我没有看到选项过滤器。
以下代码是我的视图脚本的一部分:
Ext.define('Project.my.name.space.EventList', {
extend: 'Ext.form.Panel',
require: 'Ext.ux.grid.FiltersFeature',
bodyPadding: 10,
title: Lang.Main.EventsAndRegistration,
layout: {
align: 'stretch',
type: 'vbox'
},
initComponent: function () {
var me = this;
Ext.applyIf(me, {
items: [
...
{
xtype: 'gridpanel',
title: '',
store: { proxy: { type: 'direct' } },
flex: 1,
features: [filtersCfg],
columns: [
{
xtype: 'gridcolumn',
dataIndex: 'Title',
text: Lang.Main.CourseTitle,
flex: 1,
filterable: true
},
{
xtype: 'datecolumn',
dataIndex: 'StartDate',
text: Lang.Main.StartDate,
format: Lang.Main.DateFormatJS,
flex: 1,
filter: { type: 'date' }
},
{
xtype: 'datecolumn',
dataIndex: 'EndDate',
text: Lang.Main.EndDate,
format: Lang.Main.DateFormatJS,
flex: 1, // TODO: filter
},
{
xtype: 'gridcolumn',
dataIndex: 'Participants',
text: Lang.Main.Participants,
flex: 1
},
{
xtype: 'gridcolumn',
dataIndex: 'LocationName',
text: Lang.Main.Location,
flex: 1
},
{
xtype: 'gridcolumn',
dataIndex: 'Status',
text: Lang.Main.Status,
flex: 1, // TODO: filter
}],
dockedItems: [{
xtype: 'toolbar',
items: [{
icon: 'Design/icons/user_add.png',
text: Lang.Main.RegisterForEvent,
disabled: true
},
{
icon: 'Design/icons/user_delete.png',
text: Lang.Main.Unregister,
disabled: true
},
{
icon: 'Design/icons/application_view_list.png',
text: Lang.Main.Show,
disabled: true
},
{
icon: 'Design/icons/calendar_edit.png',
text: Lang.Main.EditButtonText,
hidden: true,
disabled: true
},
{
icon: 'Design/icons/calendar_add.png',
text: Lang.Main.PlanCourse,
hidden: true
}]
}]
}
]
});
me.callParent(arguments);
...
this.grid = this.query('gridpanel')[0];
this.grid.on('selectionchange', function (view, records) {
var selection = me.grid.getSelectionModel().getSelection();
var event = (selection.length == 1) ? selection[0] : null;
var registered = event != null && event.data.Registered;
me.registerButton.setDisabled(registered);
me.unregisterButton.setDisabled(!registered);
me.showButton.setDisabled(!records.length);
me.editButton.setDisabled(!records.length);
});
}
});
这里也是代码的{} 3}}

刚刚调试时注意到我在此行的FiltersFeature.js
文件中收到了JS错误:
createFilters: function() {
var me = this,
hadFilters = me.filters.getCount(),
grid = me.getGridPanel(),
filters = me.createFiltersCollection(),
model = grid.store.model,
fields = model.prototype.fields,
Uncaught TypeError: Cannot read property 'prototype' of undefined
field,
filter,
state;
请帮帮我!
答案 0 :(得分:1)
有一些语法错误。
FiltersFeature
是网格功能,而不是组件。extend
一个对象文字(如果我错了,请纠正我)像这样使用过滤器:
var filtersCfg = {
ftype: 'filters',
local: true,
filters: [{
type: 'numeric',
dataIndex: 'id'
}]
};
var grid = Ext.create('Ext.grid.Panel', {
features: [filtersCfg]
});
