用法：

var userPassword=new Ext.form.TextField({
	inputType:'password',
	fieldLabel : '登录密码',
	allowBlank : false,
	name:"userPassword",
	width:120
});
var confirmPassword=new Ext.form.TextField({
	inputType:'password',
	fieldLabel : '确认密码',
	allowBlank : false,
	vtype: 'password',
                password: {initialPassField: 'userPassword' },
	width:120
});
