javascript - 在 extjs 4 中加载期间取消选中整体 radio 组 radio 场

Question

这里单选组中的单选字段通常是根据之前的选择来选择的。即，刷新页面时它会自动设置以前的值。但我需要清除单选组中的所有值。

this.mcmAdminServiceIndicatorsRadioGroup = new Ext.form.RadioGroup({
            width: 350,
            height: 50,
            items: [
                {
                    xtype: 'radiofield',
                    name: 'serviceIndicator',
                    fieldLabel: '',
                    inputValue: 'ADM',
                    boxLabel: 'ADM'
                },
                {
                    xtype: 'radiofield',
                    name: 'serviceIndicator',
                    margin: '0 0 0 20',
                    fieldLabel: '',
                    inputValue: 'BCK',
                    boxLabel: 'BCK'
                },
                {
                    xtype: 'radiofield',
                    name: 'serviceIndicator',
                    margin: '0 0 0 20',
                    fieldLabel: '',
                    inputValue: 'CKC',
                    boxLabel: 'CKC'
                },
                {
                    xtype: 'radiofield',
                    name: 'serviceIndicator',
                    margin: '0 0 0 20',
                    fieldLabel: '',
                    inputValue: 'BRK',
                    boxLabel: 'BRK'
                },
                {
                    xtype: 'radiofield',
                    name: 'serviceIndicator',
                    margin: '0 0 0 20',
                    fieldLabel: '',
                    inputValue: 'FMF',
                    boxLabel: 'FMF'
                }               
            ]
        });

我在另一个 radio 组组件的监听器中尝试了这三种方法..

this.mcmTaskCategoryRadiogroup = new Ext.form.RadioGroup({
            width: 205, 
            height: 50,
            items: [
                { 
                    xtype: 'radiofield', 
                    name: 'type', 
                    inputValue: 'Customer',
                    boxLabel: 'Customer', 
                    checked: true 
                },
                { 
                    xtype: 'radiofield', 
                    name: 'type', 
                    inputValue: 'Admin',
                    boxLabel: 'Admin' 
                }
            ],
            listeners: {
                scope: this, 
                change: function(radiogroup, newValue, oldValue) { //will be trigger twice, one with both fields, and second with the new field

                    if(typeof(newValue.type) == 'string') {
                        if(newValue.type === 'Admin') {
                            this.mcmPassengerFieldSet.hide();
                            this.mcmPassengerServiceIndicatorsFieldSet.hide();
                            this.mcmAdminServiceIndicatorsFieldSet.show();
                            this.mcmRequestTypeCombobox.store.loadData([{ name: 'Admin' }], false);
                            this.mcmRequestTypeCombobox.setValue('Admin');
                            //this.mcmAdminServiceIndicatorsRadioGroup.setValue(false);


//this.mcmAdminServiceIndicatorsRadioGroup.setValue({ serviceIndicator: taskType });


this.mcmAdminServiceIndicatorsRadioGroup.items.items[0].setValue(true);
                        } else if(newValue.type === 'Customer') {
                            this.mcmPassengerFieldSet.show();
                            this.mcmPassengerServiceIndicatorsFieldSet.show();
                            this.mcmAdminServiceIndicatorsFieldSet.hide();
                            this.mcmRequestTypeCombobox.store.loadData([
                                { name: '5Star' }, 
                                { name: '5Key' },
                                { name: 'Concierge Key' }, 
                                { name: 'Focus Market' }, 
                                { name: 'Sales' }, 
                                { name: 'OA VIP' },
                                // TCS:09-24-2013 modified
                                { name: 'JL VIP' },
                                { name: 'BA VIP' },
                                { name: 'IB VIP' },
                                { name: 'QF VIP' },
                                // modification ended
                                { name: 'Other'  } 
                            ], false);
                            this.mcmRequestTypeCombobox.setValue(
                                this.mcmDisplayedRecord.get('RequestType') ? this.mcmDisplayedRecord.get('RequestType') : 'Other');
                        }
                    }
                }
            }
        });

您是否尝试过从客户单选字段中删除“checked : true”？
