Javascript 實現(xiàn)復(fù)制(Copy)動作方法大全

字號:


    現(xiàn)在瀏覽器種類也越來越多,諸如 IE、Firefox、Chrome、Safari等等,因此現(xiàn)在要實現(xiàn)一個js復(fù)制內(nèi)容到剪貼板的小功能就不是一件那么容易的事了。
    一、實現(xiàn)點擊按鈕,復(fù)制文本框中的的內(nèi)容
    <script type="text/javascript">
    function copyUrl2()
    {
    var Url2=document.getElementById("biao1");
    Url2.select(); // 選擇對象
    document.execCommand("Copy"); // 執(zhí)行瀏覽器復(fù)制命令
    alert("已復(fù)制好,可貼粘。");
    }
    </script>
    <textarea cols="20" rows="10" id="biao1">用戶定義的代碼區(qū)域</textarea>
    <input type="button" onClick="copyUrl2()" value="點擊復(fù)制代碼" />二、復(fù)制專題地址和 url 地址,傳給 QQ/MSN 上的好友
    <!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd">
    <html xmlns="http://www.w3.org/1999/xhtml">
    <head>
    <meta http-equiv="Content-Type" content="text/html; charset=gb2312" />
    <title>Js復(fù)制代碼</title>
    </head>
    <body>
    <p>
    <input type="button" name="anniu1" onClick='copyToClipBoard()' value="復(fù)制專題地址和url地址,傳給QQ/MSN上的好友">
    <script language="javascript">
    function copyToClipBoard(){
    var clipBoardContent="";
    clipBoardContent+=document.title;
    clipBoardContent+="";
    clipBoardContent+=this.location.href;
    window.clipboardData.setData("Text",clipBoardContent);
    alert("復(fù)制成功,請粘貼到你的QQ/MSN上推薦給你的好友");
    }
    </script>三、直接復(fù)制 url
    <input type="button" name="anniu2" onClick='copyUrl()' value="復(fù)制URL地址">
    <script language="javascript">
    function copyUrl()
    {
    var clipBoardContent=this.location.href;
    window.clipboardData.setData("Text",clipBoardContent);
    alert("復(fù)制成功!");
    }
    </script>四、點擊文本框時,復(fù)制文本框里面的內(nèi)容
    <input onclick="oCopy(this)" value="你好.要copy的內(nèi)容!">
    <script language="javascript">
    function oCopy(obj){
    obj.select();
    js=obj.createTextRange();
    js.execCommand("Copy")
    alert("復(fù)制成功!");
    }
    </script>五、復(fù)制文本框或者隱藏域中的內(nèi)容
    <script language="javascript">
    function CopyUrl(target){
    target.value=myimg.value;
    target.select();
    js=myimg.createTextRange();
    js.execCommand("Copy");
    alert("復(fù)制成功!");
    }
    function AddImg(target){
    target.value="[IMG]"+myimg.value+"[/ img]";
    target.select();
    js=target.createTextRange();
    js.execCommand("Copy");
    alert("復(fù)制成功!");
    }
    </script>六、復(fù)制 span 標(biāo)記中的內(nèi)容
    <script type="text/javascript">
    </script>
    <br />
    <br />
    <script type="text/javascript">function copyText(obj)
    {
    var rng = document.body.createTextRange();
    rng.moveToElementText(obj);
    rng.scrollIntoView();
    rng.select();
    rng.execCommand("Copy");
    rng.collapse(false);
    alert("復(fù)制成功!");
    }
    </script>七、瀏覽器兼容  copyToClipboard("拷貝內(nèi)容")
    function copyToClipboard(txt) {
          if (window.clipboardData) {
            window.clipboardData.clearData();
            clipboardData.setData("Text", txt);
            alert("復(fù)制成功!");
          } else if (navigator.userAgent.indexOf("Opera") != -1) {
            window.location = txt;
          } else if (window.netscape) {
            try {
              netscape.security.PrivilegeManager.enablePrivilege("UniversalXPConnect");
            } catch (e) {
              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(shè)置為'true'");
            }
            var clip = Components.classes['@mozilla.org/widget/clipboard;1'].createInstance(Components.interfaces.nsIClipboard);
            if (!clip)
              return;
            var trans = Components.classes['@mozilla.org/widget/transferable;1'].createInstance(Components.interfaces.nsITransferable);
            if (!trans)
              return;
            trans.addDataFlavor("text/unicode");
            var str = new Object();
            var len = new Object();
            var str = Components.classes["@mozilla.org/supports-string;1"].createInstance(Components.interfaces.nsISupportsString);
            var copytext = txt;
            str.data = copytext;
            trans.setTransferData("text/unicode", str, copytext.length * 2);
            var clipid = Components.interfaces.nsIClipboard;
            if (!clip)
              return false;
            clip.setData(trans, null, clipid.kGlobalClipboard);
            alert("復(fù)制成功!");
          }
        }
    八、兼容各大瀏覽器的復(fù)制代碼(結(jié)合ZeroClipboard.js)
    <html>
    <head>
    <title>Zero Clipboard Test</title>
    <script type="text/javascript" src="ZeroClipboard.js"></script>
    <script language="JavaScript">
     var clip = null;
     function $(id) { return document.getElementById(id); }
     function init() {
         clip = new ZeroClipboard.Client();
         clip.setHandCursor(true);    
         clip.addEventListener('mouseOver', function (client) {
      // update the text on mouse over
      clip.setText( $('fe_text').value );
         });
        
         clip.addEventListener('complete', function (client, text) {
      //debugstr("Copied text to clipboard: " + text );
      alert("該地址已經(jīng)復(fù)制,你可以使用Ctrl+V 粘貼。");
         });
         clip.glue('clip_button', 'clip_container' );
     }
    </script>
    </head>
    <body onLoad="init()">
    <input id="fe_text" cols=50 rows=5 value=復(fù)制內(nèi)容文本1 >
    <span id="clip_container"><span id="clip_button"><b>復(fù)制</b></span></span>
    </body>
    </html>
