对于那些需要refreshFn
靠背的人,有一个PullRefreshFn扩展PullRefresh
。
我需要 PullRefresh 由 Panel 而不是 List 或 Dataview 触发,并且我还需要在用户触发 PullRefresh 时手动加载数据并将数据设置到我的 Dataview。
为此,我需要refreshFn
Sencha 2.2 之前存在的配置功能,所以这是我的实现。
PullRefreshFn(修改)
Ext.define('Ext.plugin.PullRefreshFn', {
extend: 'Ext.plugin.PullRefresh',
alias: 'plugin.pullrefreshfn',
requires: ['Ext.DateExtras'],
config: {
/**
* @cfg {Function} refreshFn The function that will be called to refresh the list.
* If this is not defined, the store's load function will be called.
*/
refreshFn: null
},
fetchLatest: function() {
if (this.getRefreshFn()) {
this.getRefreshFn().call();
} else {
var store = this.getList().getStore(),
proxy = store.getProxy(),
operation;
operation = Ext.create('Ext.data.Operation', {
page: 1,
start: 0,
model: store.getModel(),
limit: store.getPageSize(),
action: 'read',
sorters: store.getSorters(),
filters: store.getRemoteFilter() ? store.getFilters() : []
});
proxy.read(operation, this.onLatestFetched, this);
}
}
});
我的控制器
Ext.define('myApp.controller.MyController', {
extend: 'Ext.app.Controller',
requires: ['Ext.plugin.PullRefreshFn'],
...
// More code
...
// Binds the Pull Refresh to myPanel view item.
// myPanel is a panel. Not list nor dataview.
setPullRefresh: function () {
var me = this;
// We get reference to myPanel and
// we set PullRefreshFn
this.getMyPanel().setPlugins([{
xclass: 'Ext.plugin.PullRefreshFn',
docked: 'top',
// We set autoSnapBack to false,
// as we are going to trigger this manually
autoSnapBack: false,
// refreshFn will be called upon user releasing for refresh.
refreshFn: function() {
// This is a custom function that sets data to our dataview list.
// When it's done setting data, we trigger the snapBack.
me.populateMylist(function () {
me.getMyPanel().getPlugins()[0].snapBack(true);
});
}
}]);
}
});
