如果我使用这个JS代码:
<script language="javascript" type="text/javascript">
function showHideDiv()
{
var divstyle = new String();
divstyle = document.getElementById("elementId").style.visibility;
if(divstyle.toLowerCase()=="visible" || divstyle == "")
{
document.getElementById("elementId").style.visibility = "hidden";
}
else
{
document.getElementById("elementId").style.visibility = "visible";
}
}
</script>
然后这是我的HTML:
<a href="#" class="Action" id="action" onclick="return showHideDiv();">Menu</a>
<div id="elementId" style="visibility:hidden">
content here
</div>
将另一个div扩展为div但没有多个函数的最佳方法是什么?

只需添加一个函数参数:
function showHideDiv(id)
{
var element = document.getElementById(id),
visibility = element.style.visibility.toLowerCase(),
isVisible = visibility === "visible" || visibility === "";
element.style.visibility = isVisible ? 'hidden' : 'visible';
}
然后在你的HTML中,你传递它:
onclick="showHideDiv('elementId');"

尝试:
function toggleDiv(showDiv) {
var elm, divstyle, isHidden;
elm = document.getElementById("elementId");
divstyle = elm.style.visibility;
isHidden = divstyle.toLowerCase() == "visible" || divstyle == "" ? false : true;
elm.style.visibility = (showDiv === true || (isHidden && showDiv !== false) ? 'visible' : 'hidden')
}
用法:
toggleDiv() // Toggles visibility to opposite of current state.
toggleDiv(true) // Always shows div.
toggleDiv(false) // Always hides div.
