使HTML文本无法选择

时间:2012-05-04 17:04:54

标签: html

首先,我来过How to make HTML Text unselectable 但这并没有解决我的问题,(JavaScript版本运行良好,但我需要使用HTML和CSS,我不能使用JavaScript )我使用推荐的CSS,但看看我的{ {3}}将鼠标从[从这里拖动]拖动到[到此处],您将看到文本仍然可以选择。
任何方式使真的无法选择?
感谢

您可以像这样使用CSS:

<强> CSS

.unselectable {
  -webkit-user-select: none;  /* Chrome all / Safari all */
  -moz-user-select: none;     /* Firefox all */
  -ms-user-select: none;      /* IE 10+ */

  /* No support for these yet, use at own risk */
  -o-user-select: none;
  user-select: none;
}

对于较旧的IE版本,问题通常难以处理,但您可以使用行为:

<强> CSS

.unselectable {
   behavior: url(ieUserSelectFix.htc);
}

和行为文件“ieUserSelectFix.htc”:

<public:component lightweight="true">

    <public:attach event="ondocumentready" onevent="stopSelection()" />

    <script type="text/javascript">
    <!--
        function stopSelection() {
            element.onselectstart = function() { return(false); };
            element.setAttribute('unselectable', 'on', 0);
        }
    //-->
    </script>
</public:component>

使用Javascript,您可以:

yourElement.onselectstart = function() { return(false); };

在查看此问题后,想到另一种方法可以防止用户在查看页面时选择文本,基本上是在目标文本上设置掩码:

您的小提琴已更新here

示例:


<强> CSS

.wrapTxt {
  position: relative;
}
.wrapTxt .mask {
  display: block;
  position: absolute;
  top: 0;
  left: 0;
  right: 0;
  bottom: 0;
}

<强> HTML

<p class="wrapTxt">
  This is my text! My text is mine and no one Else's!
  <span class="mask"></span>
</p>

这里的原理很简单(Fiddle),在文本上有一个块元素,占用了它所有的包装空间。

如果您需要一行可选而下一行不可选,那么这次失败是一项艰难的实施。此外,“不可选”文字上的链接也不可用。

最后说明:

用户可以随时查看源代码,也可以通过从网页的顶部到底部拖动鼠标来解决此问题。

尝试这样的事情

                <!DOCTYPE html>
                <html xmlns="http://www.w3.org/1999/xhtml">

                $("#code").mouseover(function(){
                 $("body").enableTextSelect();
                });

                $("#code").mouseout(function(){  

                // Code for Deselect Text When Mouseout the Code Area
                if (window.getSelection) {
                  if (window.getSelection().empty) {  // Chrome
                    window.getSelection().empty();
                  } else if (window.getSelection().removeAllRanges) {  // Firefox
                    window.getSelection().removeAllRanges();
                  }
                } else if (document.selection) {  // IE?
                  document.selection.empty();
                }

                 $("body").disableTextSelect();
                });
                });
                </script>

                <style type="text/css">
                <!--
                body {

                }

                #code
                {
                 padding:20px;
                 border:2px dashed #CCC;
                 font-family:"Courier New", Courier, monospace;
                 font-size:15px;
                 background-color:#EEE;
                }

                </style>

编辑: 这是一种跨浏览器方法,用于使用不可选择的=“on”元素属性来阻止文本选择。

      <!DOCTYPE html>
        <html>
          <head>
            <title>Unselectable Text</title>
            <style type="text/css">
            [unselectable=on] { -moz-user-select: none; -khtml-user-select: none; user-select: none; }
            </style>
          </head>
          <body id="doc">
        <p unselectable="on">For example, the text in this paragraph
        cannot be selected.
        For example, the text in this paragraph
        cannot be selected
        For example, the text in this paragraph
        cannot be selected</p>
          </body>
           </html>
