希望这是一个简单的问题。我有一个div
我想用按钮切换隐藏/显示
<div id="newpost">
纯 JavaScript:
var button = document.getElementById('button'); // Assumes element with id='button'
button.onclick = function() {
var div = document.getElementById('newpost');
if (div.style.display !== 'none') {
div.style.display = 'none';
}
else {
div.style.display = 'block';
}
};
jQuery:
$("#button").click(function() {
// assumes element with id='button'
$("#newpost").toggle();
});
HTML:
<div id='content'>Hello World</div>
<input type='button' id='hideshow' value='hide/show'>
jQuery:
jQuery(document).ready(function(){
jQuery('#hideshow').live('click', function(event) {
jQuery('#content').toggle('show');
});
});
对于 jQuery 1.7 和更新的版本使用
jQuery(document).ready(function(){
jQuery('#hideshow').on('click', function(event) {
jQuery('#content').toggle('show');
});
});
作为参考,请查看此演示
Element.style
MDNvar toggle = document.getElementById("toggle");
var content = document.getElementById("content");
toggle.addEventListener("click", function() {
content.style.display = (content.dataset.toggled ^= 1) ? "block" : "none";
});
#content{
display:none;
}
<button id="toggle">TOGGLE</button>
<div id="content">Some content...</div>

如果您选择一种 JS / jQuery 方式来实际切换 a className
,则始终可以向元素添加动画过渡,这是一个基本示例:
var toggle = document.getElementById("toggle");
var content = document.getElementById("content");
toggle.addEventListener("click", function(){
content.classList.toggle("appear");
}, false);
#content{
/* DON'T USE DISPLAY NONE/BLOCK! Instead: */
background: #cf5;
padding: 10px;
position: absolute;
visibility: hidden;
opacity: 0;
transition: 0.6s;
-webkit-transition: 0.6s;
transform: translateX(-100%);
-webkit-transform: translateX(-100%);
}
#content.appear{
visibility: visible;
opacity: 1;
transform: translateX(0);
-webkit-transform: translateX(0);
}
<button id="toggle">TOGGLE</button>
<div id="content">Some Togglable content...</div>
这是一种简单的 Javascript 切换方式:
<script>
var toggle = function() {
var mydiv = document.getElementById('newpost');
if (mydiv.style.display === 'block' || mydiv.style.display === '')
mydiv.style.display = 'none';
else
mydiv.style.display = 'block'
}
</script>
<div id="newpost">asdf</div>
<input type="button" value="btn" onclick="toggle();">
