PHP和mxml 实现FLASH 曲线图
MXML是一个可以让你在Adobe Flex中布局用户界面组件的一种XML语言,你也可以使用MXML声明来定义程序中的非可视化组件,安装好FLEX Development 后,你就可以轻松的结合PHP完成一个FLASH曲线图.
先从PHP入手:
FLEX 和PHP的交互最常用的就是和XML的交互,就是用PHP生成XML,然后用FLEX去读取并且显示,我们以XML的形式先写一个帐目详单的数据,代码如下:
- header("Content-Type: text/xml");
- $arr = array(
- array('day'=>'01','sum'=>'153.1'),
- array('day'=>'02','sum'=>'882.86'),
- array('day'=>'03','sum'=>'456.9'),
- array('day'=>'04','sum'=>'717.7'),
- array('day'=>'05','sum'=>'255.1'),
- array('day'=>'06','sum'=>'533.1')
- );
- $xml_return .= "<bills>";
- foreach ( $arr as $use){
- $xml_return .="<bill><sum>{$use['sum']}</sum><name>{$use['day']}</name></bill> ";
- }
- $xml_return.= "</bills>";
- echo $xml_return;
显示6个月的消费记录,$arr也可以是从数据库读出来的数据,这里只是作为一个例子,所以直接给一个数组赋值.
- - <bills>
- - <bill>
- <sum>153.1</sum>
- <name>01</name>
- </bill>
-
- - <bill>
- <sum>882.86</sum>
- <name>02</name>
- </bill>
-
- - <bill>
- <sum>456.9</sum>
- <name>03</name>
- </bill>
-
- - <bill>
- <sum>717.7</sum>
- <name>04</name>
- </bill>
-
- - <bill>
- <sum>255.1</sum>
- <name>05</name>
- </bill>
-
- - <bill>
- <sum>533.1</sum>
- <name>06</name>
- </bill>
-
- </bills>
Php部分就完成了,接下来是写MXML,实例代码如下:
- <?xml version="1.0" encoding="utf-8"?>
- <?xml version="1.0" encoding="utf-8"?>
- <mx:Application xmlns:mx="http://www.adobe.com/2006/mxml" layout="absolute" creationComplete="getaccount()">
- <mx:HTTPService id="listRequest" url="" useProxy="false" method="POST">
- <mx:request xmlns=""> </mx:request>
- </mx:HTTPService>
-
- <mx:Script><![CDATA[
- import mx.rpc.events.ResultEvent;//引用ResultEvent类
- public function getaccount():void{
- listRequest.url='http://localhost/arr.php';
- listRequest.send();
- }
- ]]></mx:Script>
- <mx:LineChart showDataTips="true" clipContent="false" x="126" y="10" id="tongjitu" dataProvider="{listRequest.lastResult.bills.bill}" width="678">
- <mx:horizontalAxis>
- <mx:CategoryAxis dataProvider="{listRequest.lastResult.bills.bill}" categoryField="name" title="(日)" />
- </mx:horizontalAxis>
- <mx:series>
- <mx:LineSeries displayName="每日消费" yField="sum" xField="name"/>
- </mx:series>
- </mx:LineChart>
- </mx:Application>
逐一解释一下:
- Application
- creationComplete="getaccount()"
- 〈mx:HTTPService id="listRequest" url="" useProxy="false" method="POST"〉
- 〈mx:request xmlns=""〉 〈/mx:request〉
- 〈/mx:HTTPService〉
-
- mx:Script
下面分析下getaccount函数:
- public function getaccount():void{
- listRequest.url='http://localhost/arr.php';
- listRequest.send();
- }
-
-
-
- mx:LineChart
-
- dataProvider :数据源:listRequest.lastResult.bills.bill
- bills.bill 是XML里面的标签
-
- mx:LineSeries displayName="每日消费" yField="sum" xField="name"
