js实现复制到剪切板

// <![CDATA[

    function copy_clip(copy)

    {

        if (window.clipboardData)

        {

            window.clipboardData.setData("Text", copy);

        }

        else if (window.netscape)

        {

            netscape.security.PrivilegeManager.enablePrivilege('UniversalXPConnect');

            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 = copy;

            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("Successfully copied");

        return false;

   }

　　用法:

<img src="@Url.Content("~/Content/images/copycode.gif")" onclick="copy_clip($('#txtaddress').html());" class="info-img"/>

        <p class="info-font-content" style="width: 150px; color: #5F5F5F;" id="txtaddress">28320 Parcells Rd NE Kingstorn, WA 98346</p>
