我想通过调用它的ID切换div。该元素是柔性容器内的柔性物品，初始display设置为none。我的Flex项目不会显示一个JavaScript类别切换
<div id="header-menu-button" onclick="headerMenuToggle()">
...
</div>
<div id="header">
...
<nav id="header-menu-wrapper" class="header-menu-wrapper" role="navigation" aria-label="Alternate Menu">
...
</nav>
...
</div>
<style>
.header {
display: -webkit-flex;
display: flex;
-webkit-flex-flow: row wrap;
flex-flow: row wrap;
-webkit-justify-content: space-between;
justify-content: space-between;
-webkit-align-items: center;
align-items: center;
}
.header > * {
-webkit-flex: 1 100%;
-ms-flex: 1 100%;
-moz-flex: 1 100%;
flex: 1 100%;
}
.header-menu-wrapper {
display: none;
}
.show {
display:-webkit-flex;
display:flex;
}
</style>
<script>
function headerMenuToggle() {
document.getElementById("header-menu-wrapper").classList.toggle("show");
}
</script>
