### confform
如果一个事件处理需要用户确认可以在事件处理中指定一个conform属性来引发当此事件发生时会弹出一个确认窗口用户确认后才会处理此事件否则不处理
### urlwidget绑定
urlwidget事件处理方法是从后台获取一个控件描述文件动态生成bricks控件并将控件添加添加添加或替换到事件处理指定的控件中。
urlwidget绑定需要一个options属性和一个mode属性在此属性中需要
* url字符串类型 获取desc数据的url
* mehtod字符串类型url调用的方法缺省”GET“
* params对象类型调用的参数
绑定创建的控件添加到target控件中
请参考[例子](../../examples/urlwidget.ui)
```

在上述例子中我们使用了一个竖向排列的容器VBox并在此容器中添加了两个字控件分别是一个横向排列的容器HBox和一个填充器Filler
并在横向排列的子控件中添加了3个按钮控件, 每个Button定义了id 分别是replaceinsert和append在主控件VBox的binds中分别定义了三个事件处理分别对应于3个Button的click事件演示了三种子控件在target控件中插入的模式替换所有子控件插入在已有子控件之前添加到已有子控件之后

```
上述例子中三个Button分别驱动app中textsize_smaller()textsize_bigger()来改变bricks字符大小从而影响到text_1控件的显示大小
### script
绑定脚本,此方法将事件绑定到一个脚本,支持以下属性
* script字符串脚本正文
* params对象类型脚本可以访问params变量来获取参数。
脚本中可以使用以下变量:
* this 事件处理中target对应的控件实例
* params参数对象datawidget获得的数据会添加到params中
例子
```
{
"id":"insert",
"widgettype":"Button",
"options":{
"width":"80px",
"i18n":true,
"label":"click me"
},
"binds":[
{
"wid":"self",
"event":"click",
"actiontype":"script",
"target":"self",
"script":"console.log(this, params, event);"
}
]
}
```
在上述例子中定义了使用“script”事件处理方法来处理Button的“click事件” 在click后在控制台上把事件传过来的参数显示出来

在上述例子中使用bricks.RF注册了一个setText函数 并在主控件的binds区域定义了当changetext按钮点击后调用注册函数“setText”来处理
### event
绑定事件需指定target触发target对象的一个事件
支持以下属性
dispatch_event需触发的事件名
params传递给事件的参数处理函数可以使用evemt.params获得此参数
作为参数调用target实例的方法
```
{
"widgettype":"VBox",
"options":{},
"subwidgets":[
{
"id":"btn1",
"widgettype":"Button",
"options":{
"label":"press me"
}
},
{
"id":"txt1",
"widgettype":"Text",
"options":{
"otext":"I will dispatch a event when btn1 pressed",
"i18n":true
}
}
],
"binds":[
{
"wid":"btn1",
"event":"click",
"actiontype":"event",
"target":"txt1",
"dispatch_event":"gpc"
},
{
"wid":"txt1",
"event":"gpc",
"actiontype":"script",
"target":"self",
"script":"alert('yield');"
}
]
}
```
上述例子中在主控件的binds区域定义了btn1的按钮点击后使用event处理类型来处理btn1的click事件即转而触发“txt1”正文控件的“gpc”事件并定义了当”txt1“正文控件在gpc事件发生后使用script事件处理方法alert一个消息
