我的页面上定义了fieldset
。现在我想在按钮点击事件上启用或禁用此字段集。但它不能正常工作。以下是我写的代码:
要停用:
this.mySettings.query('[name="fieldsetName"]').forEach(function (field) {
field.disable();
});
启用:
this.mySettings.query('[name="fieldsetName"]').forEach(function (field) {
field.enable();
});
我需要一份解决这两个问题的工作样本。
目前我正在使用version 4.2
ExtJs

您应该在字段集上调用setDisabled
函数。它将禁用所有包含的组件。
fieldset.setDisabled(true);
// the fieldset and all inner components are disabled
fieldset.setDisabled(false);
// the fieldset and all inner components are enabled
See the Sencha ExtJs 4.2.0 documentation和 the following minimal working example can be found on Sencha Fiddle
Ext.create('Ext.panel.Panel',{
items: [{
xtype: 'fieldset',
itemId: 'fieldsetId',
items: [{
xtype: 'checkbox',
fieldLabel: 'Check 1'
},{
xtype: 'checkbox',
fieldLabel: 'Check 2'
},{
fieldLabel: 'Combo 1',
xtype: 'combobox',
store: ['value1','value2','value3']
}]
}, {
xtype: 'button',
text: 'Disable fieldset',
handler: function (button) {
var fieldset = Ext.ComponentQuery.query('panel > #fieldsetId')[0];
var toggle = !fieldset.isDisabled();
var text = (toggle ? 'Enable' : 'Disable') + ' fieldset';
fieldset.setDisabled(toggle);
button.setText(text);
}
}],
renderTo: Ext.getBody()
});

将其粘贴到Sencha fiddle并点击运行:
Ext.application({
name : 'Fiddle',
launch : function() {
Ext.Msg.alert('Fiddle', 'Welcome to Sencha Fiddle!');
Ext.create('Ext.window.Window', {
height: '100%',
width: '100%',
autoShow:true,
bodyPadding: 25,
title:'win',
items: [{
xtype: 'fieldset',
items: [{
xtype: 'checkbox',
fieldLabel: 'field1'
},{
xtype: 'checkbox',
fieldLabel: 'field2'
},{
fieldLabel: 'field3',
xtype: 'combo',
store: ['asdf','zzasdf','dfdf']
}]
}, {
xtype: 'button',
text: 'Enable/Disable entire fieldset',
handler: function(btn){
var fset = btn.up('window').down('fieldset');
fset.setDisabled(!fset.disabled);
}
}, {
margin: '0 0 0 10',
xtype: 'button',
text: 'Enable/Disable each field in fieldset individually',
handler: function(btn){
var fset = btn.up('window').down('fieldset');
fset.items.each(function(i){
i.setDisabled(!i.disabled);
});
}
}]
});
}
});
