我有一个项目,我使用HTML CSS和JavaScript创建一个虚拟工作站。
代码工作顺利,完美,如下图所示(减去图像)

<b>ABOUT MALFUNCTION COMPUETER</b>
<p>Malfunction compueter is a 非常好的 computer software OS that runs on 你的电脑屏幕上 in the programming language 语文。.</p><br>
<p>In order to get the best out of malfunction compueter, one must 把你的脸爆炸,然后, and then one must also 死掉。这样.</p>

</select></div>
</html>
&#13;
但是,有一组线路无法正常运行:
<div id="languageMenu" class="innerInner" style="display: none"><p>Choose your language:</p><br><br><select>
<option>English</option>
<option>Chinese</option>
<option>Japanese</option>
</select></div>
^这是DIV
&#34;#languageMenu&#34;,用户选择他的语言。
在这里,我有一个按钮#34;#language&#34;点击后,应该是#34;#languageMenu&#34;出现。
$("#language").on("click",function(){
$("#languageMenu").fadeIn(500)
})
奇怪的是,当我在谷歌浏览器上运行它时,这不起作用,但当我把它放在JSFiddle中时,它会产生奇怪的结果。

从Chrome中,只有在按下退出按钮后才会显示语言菜单,然后立即淡出。
为什么会这样,以及哪些修正可能会使代码更好?

将每个事件绑定放在doc ready块中:
$(document).ready(function() {
$(".inner").fadeOut(0)
$("#exit").fadeOut(0)
$("#exitText").fadeOut(0)
$("#languageMenu").fadeOut(0)
$("#about").on("click", function() {
$("#info").fadeIn(500)
$("#exit").fadeIn(500)
$("#exitText").fadeIn(500)
$("#fangNiu").fadeIn(500)
$("#backgroundImage").fadeOut(500)
})
$("#settings").on("click", function() {
$("#options").fadeIn(500)
$("#exit").fadeIn(500)
$("#exitText").fadeIn(500)
$("#fangNiu").fadeIn(500)
$("#backgroundImage").fadeOut(500)
})
$("#apps").on("click", function() {
$("#applications").fadeIn(500)
$("#exit").fadeIn(500)
$("#exitText").fadeIn(500)
$("#fangNiu").fadeIn(500)
$("#backgroundImage").fadeOut(500)
})
$("html").on("click", "#exit", function() {
$("#exit").fadeOut(500)
$("#exitText").fadeOut(500)
$(".inner").fadeOut(500)
$("#fangNiu").fadeOut(500)
$("#languageMenu").fadeOut(500)
$("#backgroundImage").fadeIn(500)
})
$("#language").on("click", function() {
$("#languageMenu").fadeIn(500)
})
})
因为您的按钮出现在事件绑定之后,因此没有事件绑定在此元素上并导致错误。这就是为什么将事件绑定放在doc ready块中总是安全的。
或者您可以将脚本移至</body>
的结束位置。

您的inproper缩进模糊了错误,但是在绑定DOMReady
单击侦听器之前,您正在关闭#language
侦听器。因此,添加单击侦听器时,DOM中不存在#language
。
