javaScript settimeout工作良好。但是不透明度从1至0.5开始。如何在SettieMout模式下固定不透明度0.50?
jQuery(document).ready(function() {
document.getElementById('load').style.visibility = "visible";
document.getElementById('load').style.width = '100' + '%';
document.getElementById('load').style.height = '100' + '%';
document.getElementById('load').style.position = 'initial';
document.getElementById('load').style.backgroundImage = "url('image/load.gif')";
jQuery('#load').fadeOut(3000);
});
#load {
background-repeat: no-repeat;
background-position: center;
opacity: 0.50 !important;
z-index: 999;
}
<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script>
<body>
<div id='load'>
</div>
</body>
查看以下内容。尝试使用animate
var x = document.getElementById('load');
$(x).animate({opacity:0.5},3000);
希望这会有所帮助..!
您可以像以下方式一样做:
html,CSS和JS
jQuery(document).ready(function() {
setTimeout(function() {
jQuery('#load').removeClass('active');
}, 1000)
});
#load {
position: fixed;
height: 100%;
width: 100%;
top: 0;
left: 0;
transition: 0.5s;
text-align: center;
display: none;
}
#load.active {
display: block;
transition: 0.5s;
}
<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script>
<div id='load' class="active">
<img src="https://upload.wikimedia.org/wikipedia/commons/b/b1/Loading_icon.gif">
</div>
