我正在用jquery创建一个切换按钮。我看过youtube(lynda.com)关于如何使用jquery创建切换按钮的教程。我尝试复制代码,但“p tag”下的内容没有显示。它在教程上完美运行。我不擅长javascript。也许你可以看到我错过的或者图书馆idk。这是我的代码。提前谢谢你。
HTML:
<div id="toggle">
<div id="poptext"> toggle </div>
<div id="box">
<p> hello</p>
</div>
</div>
CSS:
#toggle {
position: fixed;
bottom: 0px;
left: 50%;
width: 240px;
margin: 0 auto;
margin-bottom: 10px;
margin-left: -120px;
}
#box {
margin: 0 auto;
position: relative;
margin-bottom: 10px;
margin-top: 10px;
border-radius: 19px;
text-shadow: 0 1px 2px #000;
background-color: #644d52;
display: none;
opacity: .9;
}
#box p {
margin: 0;
padding: 5px 20px 15px 20px;
text-align: left;
color: #FFF;
}
#poptext {
width: 50px;
height: 18px;
font-size: 14px;
text-align: left;
padding-left: 23px;
overflow: hidden;
cursor: pointer;
margin: 0 auto;
border-radius: 10px;
}
#poptext.highlight {
background: url("images/blue.jpg") no-repeat 5px 18px rgba(255, 128, 0, 0.8);
}
JAVASCRIPT:
<script>
window.jQuery || document.write('script src=\'jquery.min.js\'></script>');
$(document).ready(function () {
$('#poptext').click(function () {
$('#poptext').toggleClass('#highlight');
$('#box').animate({
height: 'toggle',
opacity: 'toggle',
width: 'toggle'
}, 500);
});
});
</script>

此处有2个问题,1个附加脚本标记为won't work,您需要split it,其次需要等待脚本加载以执行代码。您可以使用窗口load
事件来执行此操作
document.write('<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></' + 'script>');
window.addEventListener('load', function() {
$('#poptext').click(function() {
$('#poptext').toggleClass('#highlight');
$('#box').animate({
height: 'toggle',
opacity: 'toggle',
width: 'toggle'
}, 500);
});
})
