Flex 文本控件实现自定义复制粘贴
由于添加了自定义右键菜单，导致Textinput控件默认的右键复制粘贴功能被屏蔽了。最后通过JS脚本实现这个功能，参考代码如下
1 <?xml version="1.0" encoding="utf-8"?> 2 <s:Application xmlns:fx="http://ns.adobe.com/mxml/2009" 3 xmlns:s="library://ns.adobe.com/flex/spark" 4 xmlns:mx="library://ns.adobe.com/flex/mx" minWidth="955" minHeight="600" creationComplete="init()"> 5 <s:layout> 6 <s:VerticalLayout/> 7 </s:layout> 8 <fx:Declarations> 9 <!-- 将非可视元素（例如服务、值对象）放在此处 --> 10 <fx:XML id="jsxml" > 11 <script> 12 <![CDATA[ 13 14 function clipboardOperator(type,browsername,txt){ 15 if(type!="init"){ 16 if(type=="copy"){ 17 window.clipboardData.setData("Text", txt); 18 return; 19 } 20 else if(type=="paste"){ 21 var clipboard=window.clipboardData.getData("Text"); 22 if(clipboard == null){ 23 alert('您的剪切板中没有任何文本内容'); 24 return ; 25 } 26 else 27 return clipboard; 28 } 29 } 30 } 31 ]]> 32 </script> 33 </fx:XML> 34 </fx:Declarations> 35 <fx:Script> 36 <![CDATA[ 37 import Class.URLUtil; 38 39 import flash.external.ExternalInterface; 40 41 import flash.desktop.Clipboard; 42 import flash.desktop.ClipboardFormats; 43 import mx.controls.Alert; 44 45 private var browsername:String=URLUtil.getBrowserName(); 46 47 private function init():void{ 48 49 lbpaste.text=ExternalInterface.call(jsxml, "init"); 50 } 51 52 protected function btncopy_clickHandler(event:MouseEvent):void 53 { 54 //内部复制功能 55 Clipboard.generalClipboard.clear(); 56 Clipboard.generalClipboard.setData(ClipboardFormats.TEXT_FORMAT,txt.text,false); 57 //调用JS脚本实现复制 58 // ExternalInterface.call("copypasteOperator","copy", txt.text); 59 } 60 61 protected function btnpaste_clickHandler(event:MouseEvent):void 62 { 63 lbpaste.text=ExternalInterface.call("clipboardOperator","paste",browsername); 64 } 65 ]]> 66 </fx:Script> 67 <s:TextInput id="txt" text="aaa"/> 68 <s:Button id="btncopy" label="复制" click="btncopy_clickHandler(event)"/> 69 <s:Button id="btnpaste" label="粘贴" click="btnpaste_clickHandler(event)"/> 70 <s:Label id="lbpaste"/> 71 </s:Application>
注：目前只支持IE和搜狗浏览器
