我正在开发一个移动网站,并希望将JS用于添加和删除类。因此,为了保持良好和轻松,我不想使用jQuery。
我有以下HTML:
<div id="masthead">
<a href="index.html" title="Home" id="brand">Brand</a>
<a href="#" id="openPrimaryNav">Menu</a>
<ul id="primaryNav" class="">
<li><a href="index.html" title="Home">Home</a></li>
<li><a href="benefits.html" title="Benefits">Benefits</a></li>
<li><a href="features.html" title="Features">Features</a></li>
<li><a href="casestudies.html" title="Case Studies">Case Studies</a></li>
<li><a href="instore.html" title="In Store">In-Store</a></li>
<li><a href="contact.html" title="Contact">Contact Us</a></li>
<li id="closePrimaryNav"><a href="#" title="Contact">Close Menu</a></li>
</ul>
</div>
到目前为止和以下JS:
window.onLoad = init;
function init()
{
document.getElementById('openPrimaryNav').onClick = openPrimaryNav();
document.getElementById('closePrimaryNav').onClick = closePrimaryNav();
}
function openPrimaryNav()
{
document.getElementById('primaryNav').className = 'open';
}
function closePrimaryNav()
{
document.getElementById('primaryNav').className = '';
}
我不能让这个工作能让任何人告诉我我做错了什么?非常感谢提前。
根据以下提供的答案纠正JS:
window.onload = init;
function init()
{
document.getElementById('openPrimaryNav').onclick = openPrimaryNav;
document.getElementById('closePrimaryNav').onclick = closePrimaryNav;
}
function openPrimaryNav()
{
document.getElementById('primaryNav').setAttribute('class','open');
}
function closePrimaryNav()
{
document.getElementById('primaryNav').setAttribute('class','');
}
答案 0 :(得分:7)
您可以使用setAttribute
。
window.onload = init;
function init()
{
document.getElementById('openPrimaryNav').onclick = openPrimaryNav;
document.getElementById('closePrimaryNav').onclick = closePrimaryNav;
}
function openPrimaryNav()
{
document.getElementById('primaryNav').setAttribute('class','open');
}
function closePrimaryNav()
{
document.getElementById('primaryNav').setAttribute('class','');
}

它是.onclick
,而不是.onClick
