我正在尝试编写一个小书签,可以从活动页面中提取一些文本并将其加载到剪贴板中.

提取很容易,但我真的很难做剪贴板复制部分.目前,我只是提醒文本并按Ctrl C复制消息框中的文本,这是不理想的.

我已经阅读了How to Copy to Clipboard in JavaScript以及其他建议我使用zeroclipboard的问题,但我不知道如何使用bookmarklet来完成这项工作,考虑到我必须加载外部flash和javascript资源才能使用该库.

我没有弄乱页面的DOM来实现这一点,或者必须在我的浏览器(谷歌浏览器)上启用一些权限,考虑到这只是一个私人书签.

任何指针将不胜感激.

解决方法:

几个免责声明：

我做了一个bookmarklet generator,让我更容易创建bookmarklet.

它启用了jQuery,但这并不意味着你必须使用jQuery.

您可以check out the source查看如何通过书签将另一个脚本/库导入页面.

特别是,导入jQuery的行：

if (!window.zbooks)
  {
    //if zbooks hasn't been set, initialize it

    //s used for the Script element
    var s = document.createElement('script');
    //r used for the Ready state
    var r = false;
    //set the script to the latest version of jQuery
    s.setAttribute('src', 'http://code.jquery.com/jquery-latest.min.js');
    //set the load/readystate events
    s.onload = s.onreadystatechange = function()
    {
/**
 * LOAD/READYSTATE LOGIC
 * execute if the script hasn't been ready yet and:
 * - the ready state isn't set
 * - the ready state is complete
 *   - note: readyState == 'loaded' executes before the script gets called so
 *     we skip this event because it wouldn't have loaded the init event yet.
 */
      if ( !r && (!this.readyState || this.readyState == 'complete' ) )
      {
        //set the ready flag to true to keep the event from initializing again
        r = true;
        //prevent jQuery conflicts by placing jQuery in the zbooks object
        window.zbooks = {'jQuery':jQuery.noConflict()};
        //make a new zbook
        window.zbooks[n] = new zbooks(c);
      }
    };
    //append the jQuery script to the body
    b.appendChild(s);
  }

我希望有所帮助.
