再次使用另一个ExtJS查询。我有一个具有SummaryGroup功能的网格,该功能可以从面板标题上的工具按钮切换(启用/禁用)。启用一次正确显示,禁用然后尝试启用该功能。分组发生了,但是这些小组的Summery总数又没有回来了?
JS在这里摆弄:http://jsfiddle.net/hD4C4/1/
在小提琴中它会显示小组总数然后如果你禁用并重新启用它们会消失吗?
这是按下按钮一次的图片:
在禁用它然后再次重新启用它之后,这是相同的网格:
下面是面板标题工具按钮上的切换代码:
xtype: 'tool',
type: 'expand',
tooltip: 'Enable grouping',
handler: function(e, target, panelHeader, tool){
var serviceGridView = Ext.getCmp('serviceOverview').getView('groupingFeature'),
gridFeature = serviceGridView.getFeature('serviceOverviewGroupingFeature');
if (tool.type == 'expand') {
gridFeature.enable();
tool.setType('collapse');
tool.setTooltip('Disable grouping');
} else {
gridFeature.disable();
Ext.getCmp('serviceOverview').setLoading(false,false);
Ext.getCmp('serviceOverview').getStore().reload();
tool.setType('expand');
tool.setTooltip('Enable grouping');
}
}
这是我的网格代码(功能函数位于顶部:
var groupingFeature = Ext.create('Ext.grid.feature.GroupingSummary', {
groupHeaderTpl: Ext.create('Ext.XTemplate',

看起来像虫子。
我对代码进行了一些分析,发现此问题是由generateSummaryData
方法中的问题引起的。在此方法中,您可以找到以下代码:
if (hasRemote || store.updating || groupInfo.lastGeneration !== group.generation) {
record = me.populateRecord(group, groupInfo, remoteData);
if (!lockingPartner || (me.view.ownerCt === me.view.ownerCt.ownerLockable.normalGrid)) {
groupInfo.lastGeneration = group.generation;
}
} else {
record = me.getAggregateRecord(group);
}
首次渲染网格时,首先对所有组执行分支,然后重新启用 - 第二个分支。调用getAggregateRecord
而不是populateRecord
会产生空摘要记录。我没有更深入,所以现在我只能给你肮脏的黑客来覆盖它(强制代码进入第一个分支):
store.updating = true;
feature.enable();
store.updating = false;
JSfiddle:http://jsfiddle.net/P2e7s/6/
经过一番挖掘后,我发现很可能会出现此问题,因为调用group.generation
时populateRecord
不会增加。因此group.generation
始终等于1
,因此仅当lastGeneration
为空(第一次代码传递)时才会填充记录。重新启用功能后,系统会创建新组,但也会将generation
设置为1
。
所以我提出了不那么肮脏的黑客行为:
Ext.define('Ext.override.grid.feature.AbstractSummary', {
override: 'Ext.grid.feature.GroupingSummary',
populateRecord: function (group, groupInfo, remoteData) {
++group.generation;
return this.callParent(arguments);
}
});
使用该覆盖,您可以简单地启用功能,它应该可以工作。
