我在頁面上有一個加載微調器,在單擊按鈕幾秒鐘后顯示。我試圖在加載圓圈的中間添加一個加載文本,但它也在旋轉。如何阻止文本旋轉?我認為 span 標簽不受 css 轉換的影響。
function load() {
document.getElementById("loader").style.display = "block";
setTimeout(function() {
document.getElementById("loader").style.display = "none";
}, 4000);
}
.centered {
text-align: center;
position: fixed;
top: 50%;
left: 50%;
margin-top: -50px;
margin-left: -50px;
}
#loader {
position: absolute;
left: 50%;
top: 50%;
z-index: 1;
width: 150px;
height: 150px;
margin: -75px 0 0 -75px;
border: 16px solid #ffffffbb;
border-radius: 50%;
border-top: 16px solid #9c5eb8b6;
-webkit-animation: spin 2s linear infinite;
animation: spin 2s linear infinite;
}
@-webkit-keyframes spin {
0% {
-webkit-transform: rotate(0deg);
}
100% {
-webkit-transform: rotate(360deg);
}
}
@keyframes spin {
0% {
transform: rotate(0deg);
}
100% {
transform: rotate(360deg);
}
}
.loading-text {
width: 90px;
position: absolute;
top: calc(50% - 15px);
left: calc(50% - 45px);
text-align: center;
}
<button type='button' onclick='load()'>Click</button>
<div class="centered">
<div id="loader" style="display:none">
<span class="loading-text">Loading...</span>
</div>
</div>

不要將微調器和文本都放在同一個元素中,而是添加另一個。所以我們只能旋轉那個。
我把它命名為.spinner,旁邊是loading-text:
function load() {
document.getElementById("loader").style.display = "block";
setTimeout(function(){
document.getElementById("loader").style.display = "none"; }, 4000);
}
.centered {
text-align: center;
position: fixed;
top: 50%;
left: 50%;
margin-top: -50px;
margin-left: -50px;
}
.spinner {
-webkit-animation: spin 2s linear infinite;
animation: spin 2s linear infinite;
border: 16px solid #ffffffbb;
border-radius: 50%;
border-top: 16px solid #9c5eb8b6;
position: absolute;
left: 50%;
top: 50%;
z-index: 1;
width: 150px;
height: 150px;
margin: -75px 0 0 -75px;
}
@-webkit-keyframes spin {
0% { -webkit-transform: rotate(0deg); }
100% { -webkit-transform: rotate(360deg); }
}
@keyframes spin {
0% { transform: rotate(0deg); }
100% { transform: rotate(360deg); }
}
.loader, .loading-text {
width: 90px;
position: absolute;
top: calc(50% - 15px);
left: calc(50% - 45px);
text-align: center;
}
<button type='button' onclick='load()'>Click</button>
<div class="centered">
<div id="loader" style="display:none">
<div class="spinner"></div>
<span class="loading-text">Loading...</span>
</div>
</div>

或者你可以使用pseudo-element像:
function load() {
document.getElementById("loader").style.display = "block";
}
.centered {
text-align: center;
position: fixed;
top: 50%;
left: 50%;
margin-top: -60px;
margin-left: -60px;
}
#loader {
position: absolute;
}
#loader:before{
content: "";
position: absolute;
left: 50%;
top: 50%;
width: 150px;
height: 150px;
margin: -75px 0 0 -75px;
border: 16px solid #ffffffbb;
border-radius: 50%;
border-top: 16px solid #9c5eb8b6;
-webkit-animation: spin 2s linear infinite;
animation: spin 2s linear infinite;
}
@-webkit-keyframes spin {
0% {
-webkit-transform: rotate(0deg);
}
100% {
-webkit-transform: rotate(360deg);
}
}
@keyframes spin {
0% {
transform: rotate(0deg);
}
100% {
transform: rotate(360deg);
}
}
.loading-text {
width: 90px;
position: absolute;
top: calc(50% - 15px);
left: calc(50% - 45px);
text-align: center;
}
<button type='button' onclick='load()'>Click</button>
<div class="centered">
<div id="loader" style="display:none">
<span class="loading-text">Loading...</span>
</div>
</div>
