1)字段集有一个名为setInstructions
,你可以打电话到更新的说明方法。因此,您可以在字段集中指定id
配置,然后在想要更新说明时稍后使用该配置。
...
items: [
{
xtype: 'fieldset',
id: 'fieldset',
title: 'Login',
instructions: 'Please enter your credentials',
defaults: {
required: true,
labelAlign: 'left',
labelWidth: '40%'
},
items: [
{
xtype: 'emailfield',
name : 'email',
label: 'Email',
placeHolder: '[email protected]',
useClearIcon: true
}, {
xtype: 'passwordfield',
name : 'password',
label: 'Password',
useClearIcon: false
}]
}
],
...
//wherever you want to update the instructions
var fieldset = Ext.getCmp('fieldset');
fieldset.setInstructions('My new instructions!');
2)这里就是一个简单的演示:
//create a panel, which is full screen, and will contain your form, and another item
//which you want to show at some point
var wrapper = new Ext.Panel({
fullscreen: true,
layout: 'card',
//my two items
items: [
form,
{
xtype: 'panel',
html: 'my second panel, which is not visible on render.'
}
]
});
//change the active card/item, when you need to
wrapper.setActiveItem(1); //starts at 0
确保您从表单中删除全屏,因为它不再是全屏(这个包装面板)。
