<p>You can't do this with plain vanilla HTML, so JSF can't do much for you here as well.</p>

<p>If you're targeting <a href="http://caniuse.com/#feat=user-select-none" rel="noreferrer">decent browsers</a> only, then just make use of CSS3:</p>

<pre class="lang-css prettyprint-override"><code>.unselectable {
    -webkit-touch-callout: none;
    -webkit-user-select: none;
    -khtml-user-select: none;
    -moz-user-select: none;
    -ms-user-select: none;
    user-select: none;
}
</code></pre>

<pre class="lang-html prettyprint-override"><code>&lt;label class="unselectable"&gt;Unselectable label&lt;/label&gt;
</code></pre>

<p>If you'd like to cover older browsers as well, then consider this JavaScript fallback:</p>

<pre><code>&lt;!doctype html&gt;
&lt;html lang="en"&gt;
    &lt;head&gt;
        &lt;title&gt;SO question 2310734&lt;/title&gt;
        &lt;script&gt;
            window.onload = function() {
                var labels = document.getElementsByTagName('label');
                for (var i = 0; i &lt; labels.length; i++) {
                    disableSelection(labels[i]);
                }
            };
            function disableSelection(element) {
                if (typeof element.onselectstart != 'undefined') {
                    element.onselectstart = function() { return false; };
                } else if (typeof element.style.MozUserSelect != 'undefined') {
                    element.style.MozUserSelect = 'none';
                } else {
                    element.onmousedown = function() { return false; };
                }
            }
        &lt;/script&gt;
    &lt;/head&gt;
    &lt;body&gt;
        &lt;label&gt;Try to select this&lt;/label&gt;
    &lt;/body&gt;
&lt;/html&gt;
</code></pre>

<p>If you're already using <a href="http://jquery.com" rel="noreferrer">jQuery</a>, then here's another example which adds a new function <code>disableSelection()</code> to jQuery so that you can use it anywhere in your jQuery code:</p>

<pre><code>&lt;!doctype html&gt;
&lt;html lang="en"&gt;
    &lt;head&gt;
        &lt;title&gt;SO question 2310734 with jQuery&lt;/title&gt;
        &lt;script src="http://code.jquery.com/jquery-latest.min.js"&gt;&lt;/script&gt;
        &lt;script&gt;
            $.fn.extend({ 
                disableSelection: function() { 
                    this.each(function() { 
                        if (typeof this.onselectstart != 'undefined') {
                            this.onselectstart = function() { return false; };
                        } else if (typeof this.style.MozUserSelect != 'undefined') {
                            this.style.MozUserSelect = 'none';
                        } else {
                            this.onmousedown = function() { return false; };
                        }
                    }); 
                } 
            });

            $(document).ready(function() {
                $('label').disableSelection();            
            });
        &lt;/script&gt;
    &lt;/head&gt;
    &lt;body&gt;
        &lt;label&gt;Try to select this&lt;/label&gt;
    &lt;/body&gt;
&lt;/html&gt;
</code></pre>

<p>I altered the jQuery plugin posted above so it would work on live elements.</p>

<pre><code>(function ($) {
$.fn.disableSelection = function () {
    return this.each(function () {
        if (typeof this.onselectstart != 'undefined') {
            this.onselectstart = function() { return false; };
        } else if (typeof this.style.MozUserSelect != 'undefined') {
            this.style.MozUserSelect = 'none';
        } else {
            this.onmousedown = function() { return false; };
        }
    });
};
})(jQuery);
</code></pre>

<p>Then you could so something like:</p>

<pre><code>$(document).ready(function() {
    $('label').disableSelection();

    // Or to make everything unselectable
    $('*').disableSelection();
});
</code></pre>


blocks|key|1107741|text|这里没有人发布了所有正确的CSS变体的答案，所以这里是：|type|unstyled|depth|inlineStyleRanges|entityRanges|data|1107742|-webkit-touch-callout:+none;

<p>No one here posted an answer with all of the correct CSS variations, so here it is:</p>

<pre><code>-webkit-touch-callout: none;
-webkit-user-select: none;
-khtml-user-select: none;
-moz-user-select: none;
-ms-user-select: none;
user-select: none;
</code></pre>


blocks|key|1322894|text|您的问题的完整现代解决方案是纯粹基于CSS的，但请注意，较旧的浏览器不支持它，在这种情况下，您需要退回到其他浏览器提供的解决方案。|type|unstyled|depth|inlineStyleRanges|entityRanges|data|1322895|所以在纯CSS中：|1322896|-webkit-user-select:+none;
-khtml-user-select:+none;
-moz-user-select:+none;
-ms-user-select:+none;
-o-user-select:+none;
user-select:+none;|code-block|syntax|javascript|1322897|但是，当鼠标光标停留在元素的文本上时，它仍然会变成一个插入符号，所以你可以添加：|1322898|cursor:+default;|1322899|现代CSS是相当优雅的。|1322900|entityMap^0|0|0|0|0|0|0^^$0|@$1|2|3|4|5|6|7|Q|8|@]|9|@]|A|$]]|$1|B|3|C|5|6|7|R|8|@]|9|@]|A|$]]|$1|D|3|E|5|F|7|S|8|@]|9|@]|A|$G|H]]|$1|I|3|J|5|6|7|T|8|@]|9|@]|A|$]]|$1|K|3|L|5|F|7|U|8|@]|9|@]|A|$G|H]]|$1|M|3|N|5|6|7|V|8|@]|9|@]|A|$]]|$1|O|3|-4|5|6|7|W|8|@]|9|@]|A|$]]]|P|$]]

<p>The full modern solution to your problem is purely CSS-based, but note that older browsers won't support it, in which cases you'd need to fallback to solutions such as the others have provided. </p>

<p>So in pure CSS:</p>

<pre><code>-webkit-user-select: none;
-khtml-user-select: none;
-moz-user-select: none;
-ms-user-select: none;
-o-user-select: none;
user-select: none;
</code></pre>

<p>However the mouse cursor will still change to a caret when over the element's text, so you add to that:</p>

<pre><code>cursor: default;
</code></pre>

<p>Modern CSS is pretty elegant.</p>


<p>I would like to add text to my webpage as a label and make it unselectable.</p>

<p>In other words, When the mouse cursor is over the text I would like it to not turn into a text selecting cursor at all.</p>

<p>A good example of what I'm trying to achieve is the buttons on this website (Questions,Tags,Users,...)</p>


How to make HTML Text unselectable

jQuery

我想将文本作为标签添加到我的网页中，并使其不可选。换句话说，当鼠标光标在文本上时，我希望它根本不会变成文本选择光标。我正在努力实现的一个很好的例子是这个网站上的按钮(问题，标签，用户，...)
