问题描述
通过使用此方法,我可以使用2个按钮显示/隐藏元素:
By using this method I can show/hide an element by using 2 buttons:
<script type="text/javascript">
function showStuff(id) {
document.getElementById(id).style.display = 'block';
}
function hideStuff(id) {
document.getElementById(id).style.display = 'none';
}
</script>
<input type="button" onClick="hideStuff('themes')" value="Hide">
<input type="button" onClick="showStuff('themes')" value="Show">
<div id="themes" style="display:block">
<h3>Stuff</h3>
</div>
有没有方法使用单个按钮?也许如果&
Is there a method to use a single button?? Maybe if & else?
推荐答案
您已经回答了您的问题... if
/ else
:
You've already answered your question...the use of if
/else
:
function toggle(id) {
var element = document.getElementById(id);
if (element) {
var display = element.style.display;
if (display == "none") {
element.style.display = "block";
} else {
element.style.display = "none";
}
}
}
如果你隐藏/显示 inline
或 inline-block
元素,或如果您在元素上使用 display
的非默认值,例如将div的显示
设置为inline (无论什么原因),然后尝试使用此函数
This won't be completely foolproof, in case you are hiding/showing inline
or inline-block
elements, or if you are using non-default values for display
on elements...such as setting a div's display
to "inline" (for whatever reason) and then trying to use this function
