关于Ext formPanel.getForm().submit()方法与standardSubmit属性的一些事

版本 Extjs 3.3.1 ??

查看API文档，发现formPanel.getForm()是一个BasicForm对象，submit方法定义如下：

?

submit(?Object?options?) : BasicForm

The options to pass to the action (see doAction for details).

Note: this is ignored when using the standardSubmit option.

The following code:

?

new Ext.FormPanel({    standardSubmit: true,    baseParams: {        foo: 'bar'    },    url: 'myProcess.php',    items: [{        xtype: 'textfield',        name: 'userName'    }],    buttons: [{        text: 'Save',        handler: function(){            var fp = this.ownerCt.ownerCt,                form = fp.getForm();            if (form.isValid()) {                // check if there are baseParams and if                // hiddent items have been added already                if (fp.baseParams && !fp.paramsAdded) {                    // add hidden items for all baseParams                    for (i in fp.baseParams) {                        fp.add({                            xtype: 'hidden',                            name: i,                            value: fp.baseParams[i]                        });                    }                    fp.doLayout();                    // set a custom flag to prevent re-adding                    fp.paramsAdded = true;                }                form.submit();            }        }    }]});

?

这个时候需要在formPanel本身添加参数baseParams，并在handler中添加相应的处理方法。
