讓你的 CSS 更好一點?,F在我們只需要.with_toggle為#section.
它可以在這里,在 Snippet 中播下錯誤,但會在Codepan上很好地分叉,請參閱。嘗試切換它并在 Codepan 上重新加載頁面。
// checking if our storage is not empty
if (localStorage.toggled != '') {
// set class to #section form storage value
document.getElementById("section").classList.toggle(localStorage.toggled);
}
function myFunction() {
if (localStorage.toggled != "with_toggle") {
document.getElementById("section").classList.add("with_toggle");
localStorage.toggled = "with_toggle";
} else {
document.getElementById("section").classList.remove("with_toggle");
localStorage.toggled = "";
}
}
#section {
margin-left: 50px;
margin-right: 50px;
}
#monbouton {
float: right;
font-size: 25px;
width: 50px;
height: 50px;
background-color: #F1F1F1;
border: 1px solid #F1F1F1;
}
#one1 {
float: left;
width: 40%;
height: 100px;
border: 1px solid blue;
}
.with_toggle #one1 {
width: 10%;
border: 1px solid red;
}
.with_toggle #one1 #afairedisparaitre {
display: none;
}
#two1 {
float: right;
width: 59%;
height: 100px;
border: 1px solid green;
}
.with_toggle #two1 {
width: 89%;
}
<div id="section">
<div id="one1">
<button id="monbouton" onclick="myFunction()">↔</button>
<div id="afairedisparaitre">This is DIV #one1<br /> Button toggle to CLASS .one2<br /> and reverse</div>
</div>
<div id="two1">This is DIV #two1<br /> Button toggle to CLASS .two2<br /> and reverse</div>
</div>

當然。只需創建一個 localStorage 變量來跟蹤收縮是否應該處于活動狀態,并使用它在頁面加載或類似的東西上應用您的樣式。
function shrinkActive() {
var shrink;
if (!(shrink = localStorage.getItem("shrink"))) {
localStorage.setItem("shrink", "false");
return false;
}
return JSON.parse(shrink);
}
function setShrink(active) {
var element1 = document.getElementById("one1");
var element2 = document.getElementById("two1");
if (active) {
element1.classList.add("one2");
element2.classList.add("two2");
} else {
element1.classList.remove("one2");
element2.classList.remove("two2");
}
localStorage.setItem("shrink", active.toString());
}
function myFunction() {
setShrink(!shrinkActive());
}
window.onload = function() {
setShrink(shrinkActive());
}
