js實現復制功能

JS 點擊復制Copy

1.實現點擊按鈕，復制文本框中的的內容

 1 <script type="text/javascript">
 2 function copyUrl2()
 3 {
 4 var Url2=document.getElementById("biao1");
 5 Url2.select(); // 選擇對象
 6 document.execCommand("Copy"); // 執行瀏覽器復制命令
 7 alert("已復制好，可貼粘。");
 8 }
 9 </script>
10 <textarea cols="20" rows="10" id="biao1">用戶定義的代碼區域</textarea>
11 <input type="button" onClick="copyUrl2()" value="點擊復制代碼" />

2.復制專題地址和 url 地址，傳給 QQ/MSN 上的好友

 1 <!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd">
 2 <html xmlns="http://www.w3.org/1999/xhtml">
 3 <head>
 4 <meta http-equiv="Content-Type" content="text/html; charset=gb2312" />
 5 <title>Js復制代碼</title>
 6 </head>
 7 <body>
 8 <p>
 9 <input type="button" name="anniu1" onClick='copyToClipBoard()' value="復制專題地址和url地址，傳給QQ/MSN上的好友">
10 <script language="javascript">
11 function copyToClipBoard(){
12 var clipBoardContent="";
13 clipBoardContent+=document.title;
14 clipBoardContent+="";
15 clipBoardContent+=this.location.href;
16 window.clipboardData.setData("Text",clipBoardContent);
17 alert("復制成功，請粘貼到你的QQ/MSN上推薦給你的好友");
18 }
19 </script>

3.直接復制 url

1 <input type="button" name="anniu2" onClick='copyUrl()' value="復制URL地址">
2 <script language="javascript">
3 function copyUrl()
4 {
5 var clipBoardContent=this.location.href;
6 window.clipboardData.setData("Text",clipBoardContent);
7 alert("復制成功!");
8 }
9 </script>

4.點擊文本框時，復制文本框里面的內容

1 <input onclick="oCopy(this)" value="你好.要copy的內容!">
2 <script language="javascript">
3 function oCopy(obj){
4 obj.select();
5 js=obj.createTextRange();
6 js.execCommand("Copy")
7 alert("復制成功!");
8 }
9 </script>

5.復制文本框或者隱藏域中的內容

 1 <script language="javascript">
 2 function CopyUrl(target){
 3 target.value=myimg.value;
 4 target.select();  
 5 js=myimg.createTextRange();  
 6 js.execCommand("Copy");
 7 alert("復制成功!");
 8 }
 9 function AddImg(target){
10 target.value="[IMG]"+myimg.value+"[/ img]";
11 target.select();
12 js=target.createTextRange();  
13 js.execCommand("Copy");
14 alert("復制成功!");
15 }
16 </script>

6.復制 span 標記中的內容

 1 <script type="text/javascript">
 2 </script>
 3 <br />
 4 <br />
 5 <script type="text/javascript">function copyText(obj)  
 6 {
 7 var rng = document.body.createTextRange();
 8 rng.moveToElementText(obj);
 9 rng.scrollIntoView();
10 rng.select();
11 rng.execCommand("Copy");
12 rng.collapse(false);
13 alert("復制成功!");
14 }
15 </script>

7.瀏覽器兼容 copyToClipboard("拷貝內容")

 1  function copyToClipboard(txt) {
 2             if (window.clipboardData) {
 3                 window.clipboardData.clearData();
 4                 clipboardData.setData("Text", txt);
 5                 alert("復制成功！");
 6 
 7             } else if (navigator.userAgent.indexOf("Opera") != -1) {
 8                 window.location = txt;
 9             } else if (window.netscape) {
10                 try {
11                     netscape.security.PrivilegeManager.enablePrivilege("UniversalXPConnect");
12                 } catch (e) {
13                     alert("被瀏覽器拒絕！\n請在瀏覽器地址欄輸入'about:config'并回車\n然后將 'signed.applets.codebase_principal_support'設置為'true'");
14                 }
15                 var clip = Components.classes['@mozilla.org/widget/clipboard;1'].createInstance(Components.interfaces.nsIClipboard);
16                 if (!clip)
17                     return;
18                 var trans = Components.classes['@mozilla.org/widget/transferable;1'].createInstance(Components.interfaces.nsITransferable);
19                 if (!trans)
20                     return;
21                 trans.addDataFlavor("text/unicode");
22                 var str = new Object();
23                 var len = new Object();
24                 var str = Components.classes["@mozilla.org/supports-string;1"].createInstance(Components.interfaces.nsISupportsString);
25                 var copytext = txt;
26                 str.data = copytext;
27                 trans.setTransferData("text/unicode", str, copytext.length * 2);
28                 var clipid = Components.interfaces.nsIClipboard;
29                 if (!clip)
30                     return false;
31                 clip.setData(trans, null, clipid.kGlobalClipboard);
32                 alert("復制成功！");
33             }
34         }
