ext1中Ext.form.ComboBox默认值的设置

1.在Ext.onReady(function(){之外:

// ComboBox定义
// 用户状态
Ext.namespace('Ext.userstate');
Ext.userstate.states = [
        ['0', '不可用'],
        ['1', '可用']
      ];

2.在Ext.onReady(function(){之内:

userstateExt = new Ext.form.ComboBox({
            fieldLabel: '用户状态',
            hiddenName:'userstate',
            store: new Ext.data.SimpleStore({
                fields: ['id', 'name'],
                data : Ext.userstate.states
            }),
            valueField:'id',
            value:'1',//注意默认值在此设置
            displayField:'name',
            typeAhead: true,
            mode: 'local',
            triggerAction: 'all',
            emptyText:'请选择用户状态...',
            selectOnFocus:true,
            width:200
        })
