如何創建顏色根據百分比更改的進度條 我想根據給定的值來更改顏色條的顏色以平滑更改(js & css)如何創建顏色根據百分比變化的進度條
例如:
<style>
#myBar {
position: absolute;
bottom: 0;
left: 0;
width: 100%;
background-color: #ff0000;
text-align: center;
line-height: 30px;
color: white;
border-radius: 1em;
animation: color 2s linear 0s alternate;
}
@keyframes color{
0% {background-color: #0f0;}
50% {background-color: #ff0;}
100% {background-color: #f00;}
}
</style>
該代碼在index.php文件:
0%=綠色,100%=紅色,75%=橙 該代碼在CSS(紅色和綠色之間的梯度)<script>
function move() {
var elem = document.getElementById("myBar");
var newElem = document.getElementById("percent");
var height = 1;
score = <?php echo($percentation);?>;
var id = setInterval(frame, 25);
function frame() {
if (height >= score) {
clearInterval(id);
} else {
height++;
elem.style.height = height + '%';
newElem.innerHTML = height + '%';
}
}
}
</script>
myBar是承重橫條本身的DIV %的是DIV輸出值
