关于EXT的combobox

在做项目时发现ComboBox里的输入值，后台取不到。google一把找到了。记录下具体做法。

var cb=new Ext.form.ComboBox({   
    triggerAction: 'all',   
    transform:'group',   
    width:272   
});   

方法1.http://www.iteye.com/problems/475

cb.on('blur',function(){   
    this.setValue(this.el.dom.value);   
});

方法2：http://hi.baidu.com/flying_all/blog/item/426443d7b8b442dba144df9e.html

cb.on('keydown', function(e){
    this.setValue(this.el.dom.value);
});

If specified, a hidden form field with this name is dynamically generated to store the field's data value (defaults to the underlying DOM element's name). Required for the combo's value to automatically post during a form submission. Note that the hidden field's id will also default to this name if hiddenId is not specified. The combo's id and the hidden field's ids should be different, since no two DOM nodes should share the same id, so if the combo and hidden names are the same, you should specify a unique hiddenId.
