js实现各种复制到剪贴板的方法

示例一：
<code class="js string">"text/javascript"</code><code class="js plain">></code></span> </div> <div class="line number2 index1 alt1"> <span style="color:#000000;"><code class="js keyword">function</code> <code class="js plain">copyUrl2()</code></span> </div> <div class="line number3 index2 alt2"> <code class="js plain"><span style="color:#000000;">{</span></code> </div> <div class="line number4 index3 alt1"> <span style="color:#000000;"><code class="js keyword">var</code> <code class="js plain">Url2=document.getElementById(</code><code class="js string">"biao1"</code><code class="js plain">);</code></span> </div> <div class="line number5 index4 alt2"> <span style="color:#000000;"><code class="js plain">Url2.select(); </code><code class="js comments">// 选择对象</code></span> </div> <div class="line number6 index5 alt1"> <span style="color:#000000;"><code class="js plain">document.execCommand(</code><code class="js string">"Copy"</code><code class="js plain">); </code><code class="js comments">// 执行浏览器复制命令</code></span> </div> <div class="line number7 index6 alt2"> <span style="color:#000000;"><code class="js plain">alert(</code><code class="js string">"已复制好，可贴粘。"</code><code class="js plain">);</code></span> </div> <div class="line number8 index7 alt1"> <code class="js plain"><span style="color:#000000;">}</span></code> </div> <div class="line number9 index8 alt2"> <code class="js plain"><span style="color:#000000;">
<code class="js string">"20"</code> <code class="js plain">rows=</code><code class="js string">"10"</code> <code class="js plain">id=</code><code class="js string">"biao1"</code><code class="js plain">>用户定义的代码区域
"button" onClick="copyUrl2()" value="点击复制代码" />

示例二：

"button" name= "anniu2" onClick= 'copyUrl()' value= "复制URL地址" >

<code class="js string">"javascript"</code> <code class="js plain">></code> </div> <div class="line number3 index2 alt2"> <code class="js keyword">function</code> <code class="js plain">copyUrl()</code> </div> <div class="line number4 index3 alt1"> <code class="js plain">{</code> </div> <div class="line number5 index4 alt2"> <code class="js keyword">var</code> <code class="js plain">clipBoardContent=</code> <code class="js keyword">this</code> <code class="js plain">.location.href;</code> </div> <div class="line number6 index5 alt1"> <code class="js plain">window.clipboardData.setData(</code> <code class="js string">"Text"</code> <code class="js plain">,clipBoardContent);</code> </div> <div class="line number7 index6 alt2"> <code class="js plain">alert(</code> <code class="js string">"复制成功!"</code> <code class="js plain">);</code> </div> <div class="line number8 index7 alt1"> <code class="js plain">}</code> </div> <div class="line number9 index8 alt2"> <code class="js plain">

示例三：复制专题地址和 url 地址

"-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd" >

"http://www.w3.org/1999/xhtml" >

"Content-Type" content= "text/html; charset=gb2312" />

Js复制代码

"button" name= "anniu1" onClick= 'copyToClipBoard()' value= "复制专题地址和url地址，传给QQ/MSN上的好友" >

<code class="js string">"javascript"</code> <code class="js plain">></code> </div> <div class="line number11 index10 alt2"> <code class="js keyword">function</code> <code class="js plain">copyToClipBoard(){</code> </div> <div class="line number12 index11 alt1"> <code class="js keyword">var</code> <code class="js plain">clipBoardContent=</code> <code class="js string">""</code> <code class="js plain">;</code> </div> <div class="line number13 index12 alt2"> <code class="js plain">clipBoardContent+=document.title;</code> </div> <div class="line number14 index13 alt1"> <code class="js plain">clipBoardContent+=</code> <code class="js string">""</code> <code class="js plain">;</code> </div> <div class="line number15 index14 alt2"> <code class="js plain">clipBoardContent+=</code> <code class="js keyword">this</code> <code class="js plain">.location.href;</code> </div> <div class="line number16 index15 alt1"> <code class="js plain">window.clipboardData.setData(</code> <code class="js string">"Text"</code> <code class="js plain">,clipBoardContent);</code> </div> <div class="line number17 index16 alt2"> <code class="js plain">alert(</code> <code class="js string">"复制成功，请粘贴到你的QQ/MSN上推荐给你的好友"</code> <code class="js plain">);</code> </div> <div class="line number18 index17 alt1"> <code class="js plain">}</code> </div> <div class="line number19 index18 alt2"> <code class="js plain">

示例四：点击文本框时，复制文本框里面的内容

"oCopy(this)" value= "你好.要copy的内容!" >

<code class="js string">"javascript"</code> <code class="js plain">></code> </div> <div class="line number3 index2 alt2"> <code class="js keyword">function</code> <code class="js plain">oCopy(obj){</code> </div> <div class="line number4 index3 alt1"> <code class="js plain">obj.select();</code> </div> <div class="line number5 index4 alt2"> <code class="js plain">js=obj.createTextRange();</code> </div> <div class="line number6 index5 alt1"> <code class="js plain">js.execCommand(</code> <code class="js string">"Copy"</code> <code class="js plain">)</code> </div> <div class="line number7 index6 alt2"> <code class="js plain">alert(</code> <code class="js string">"复制成功!"</code> <code class="js plain">);</code> </div> <div class="line number8 index7 alt1"> <code class="js plain">}</code> </div> <div class="line number9 index8 alt2"> <code class="js plain">
