晚上好亲爱的程序员们!
我对ExtJS中的持久面板有疑问。我有一些表单面板,我想在单个容器面板中显示。显示的形式取决于用户正在编辑的对象类型。据我了解,这可以通过以下3个陈述来实现:
问题是这似乎不起作用。如果使用2个不同的持久形式面板,它们都会粘在容器面板上。奇怪的是,当我不使用持久性面板时,它似乎确实有效,但每次将它们添加到容器时都会重新创建表单面板:
请参阅下面的工作示例:
<script type="text/javascript" language="javascript">
Ext.namespace("Ext.ARA");
Ext.onReady(function()
{
Ext.ARA.AddFormPanelDoesntWorkA = function()
{
Ext.ARA.ContainerPanel.removeAll(false);
Ext.ARA.ContainerPanel.add(Ext.ARA.FormPanelA);
Ext.ARA.ContainerPanel.doLayout();
}
Ext.ARA.AddFormPanelDoesntWorkB = function()
{
Ext.ARA.ContainerPanel.removeAll(false);
Ext.ARA.ContainerPanel.add(Ext.ARA.FormPanelB);
Ext.ARA.ContainerPanel.doLayout();
}
Ext.ARA.AddFormPanelDoesWorkA = function()
{
Ext.ARA.ContainerPanel.removeAll(true);
Ext.ARA.ContainerPanel.add(new Ext.form.FormPanel({title:'Form Panel A', padding:5, items:[new Ext.form.TextField({fieldLabel:'Panel A Field', anchor:'100%'})]}));
Ext.ARA.ContainerPanel.doLayout();
}
Ext.ARA.AddFormPanelDoesWorkB = function()
{
Ext.ARA.ContainerPanel.removeAll(true);
Ext.ARA.ContainerPanel.add(new Ext.form.FormPanel({title:'Form Panel B', padding:5, items:[new Ext.form.TextField({fieldLabel:'Panel B Field', anchor:'100%'})]}));
Ext.ARA.ContainerPanel.doLayout();
}
Ext.ARA.FormPanelA = new Ext.form.FormPanel({title:'Form Panel A', padding:5, items:[new Ext.form.TextField({fieldLabel:'Panel A Field', anchor:'100%'})]});
Ext.ARA.FormPanelB = new Ext.form.FormPanel({title:'Form Panel B', padding:5, items:[new Ext.form.TextField({fieldLabel:'Panel B Field', anchor:'100%'})]});
Ext.ARA.ContainerPanel = new Ext.Panel
({
title:'Container Panel',
bbar:new Ext.Toolbar
({
items:
[
{text:'AddFormPanelDoesntWorkA', handler:Ext.ARA.AddFormPanelDoesntWorkA},
{text:'AddFormPanelDoesntWorkB', handler:Ext.ARA.AddFormPanelDoesntWorkB}, '->',
{text:'AddFormPanelDoesWorkA', handler:Ext.ARA.AddFormPanelDoesWorkA},
{text:'AddFormPanelDoesWorkB', handler:Ext.ARA.AddFormPanelDoesWorkB}
]
})
});
Ext.ARA.Mainframe = new Ext.Viewport({layout:'fit', items:[Ext.ARA.ContainerPanel]});
});
</script>
在ExtJS中使用持久性表单面板的正确方法是什么?我在这里做错了什么?
答案 0 :(得分:0)
我尝试了你的例子并做了一些调整但没有让它工作,然后我意识到我已经使用CardLayout进行这种显示。使用“向导”类型的显示,查看演示文稿的LayoutBrowser。我认为它会给你你需要的东西。
