我需要编写一些与分页工具栏中的刷新按钮相关的操作。我该如何重写doRefresh()
方法?
this.bbar=Ext.create('Ext.PagingToolbar', {
store: store,
displayInfo: true,
displayMsg: 'Displaying records {0} - {1} of {2}',
emptyMsg: "No topics to display"
});
如果您只想做一次使用
Ext.create('Ext.PagingToolbar', {
store: store,
displayInfo: true,
displayMsg: 'Displaying records {0} - {1} of {2}',
emptyMsg: "No topics to display",
doRefresh : function(){
// Keep or remove these code
var me = this,
current = me.store.currentPage;
if (me.fireEvent('beforechange', me, current) !== false) {
me.store.loadPage(current);
}
}
});
或者适用于所有页面条。
Ext.PagingToolbar.prototype.doRefresh = function() {
// Keep or remove these code
var me = this,
current = me.store.currentPage;
if (me.fireEvent('beforechange', me, current) !== false) {
me.store.loadPage(current);
}
}
请注意,如果您这样做,每次更新EXTJS核心以确保功能性,您都需要仔细检查它两次!
Ext.create('Ext.PagingToolbar', {
store: store,
displayInfo: true,
displayMsg: 'Displaying records {0} - {1} of {2}',
emptyMsg: "No topics to display",
doRefresh : function(){
var me = this,
current = me.store.currentPage;
if (me.fireEvent('beforechange', me, current) !== false) {
me.store.loadPage(1, {
callback: function (records, operation, success) {
Ext.getCmp('educationGrid').getSelection(records, operation, success);
}
});
}
}
});
...................................
getSelection: function(records, operation, success){
var grid= Ext.getCmp('educationGrid'); //my grid
grid.getView().select(0);
}
