getValues() 还是 getFieldValues() [转]

http://www.java123.net/436578.html

ExtJS 中，下列两个方法有差别 formPanel.getForm().getValues()和formPanel.getForm().getFieldValues()

1.对于下拉控件 ComboBox前者可能拿不到下拉框的value内容，而只是拿到它显示的内容后者则拿到value的内容。

2.对于DateField前者同样是拿到显示的内容，后者则是完整的datetime, 如 Tue Jun 18 2013 00:00:00 GMT+0800 (中国标准时间Ext.urlEncode后，显示为这样的内容 2013-06-18T00:00:00 

其实这些从他们的源代码就能看出来。内容如下：/** *

Returns the fields in this form as an object with key/value pairs as they would be submitted using a standard form submit. * If multiple fields exist with the same name they are returned as an array.

*

Note: The values are collected from all enabled HTML input elements within the form, not from * the Ext Field objects. This means that all returned values are Strings (or Arrays of Strings) and that the * value can potentially be the emptyText of a field.

* @param {Boolean} asString (optional) Pass true to return the values as a string. (defaults to false, returning an Object) * @return {String/Object} */

getValues : function(asString){ 
            var fs = Ext.lib.Ajax.serializeForm(this.el.dom);       
            if(asString === true){ return fs; }       
            return Ext.urlDecode(fs);  
           },

/** * Retrieves the fields in the form as a set of key/value pairs, using the {@link Ext.form.Field#getValue getValue()} method. * If multiple fields exist with the same name they are returned as an array. * @param {Boolean} dirtyOnly (optional) True to return only fields that are dirty. * @return {Object} The values in the form */

 getFieldValues : function(dirtyOnly){ 
                        var o = {},  n, key, val;
                        this.items.each(function(f) { 
                           if (!f.disabled && (dirtyOnly !== true || f.isDirty())) { 
                                   n = f.getName(); 
                                   key = o[n];               
                                   val = f.getValue(); 
                                  if(Ext.isDefined(key)){ 
                                          if(Ext.isArray(key)){
                                                 o[n].push(val);
                                           }else{
                                                 o[n] = [key, val];
                                           }
                                  }else{ 
                                          o[n] = val; 
                                  }           
                            }       
                        });       
                        return o;
