When using PDFObject.js, due to the need to convert data in the background, a blank page is displayed for a long time when displayed in the foreground, so I thought of writing a fake loading animation

script fragment:

<script type="text/javascript">
var bar = 0; 
var line = "||" ; 
var amount ="||" ; 
function count(){ 
bar= bar+2 ; 
amount =amount + line; 
$("#chart").val(amount);
$("#percent").val(bar+"%"); 
if (bar<99){
//设置1.5秒循环一次
setTimeout("count()",150);
}else{
$("#beforeSee").hide();
$("#pdfSee").show();
};
};
window.onload = function (){
PDFObject.embed("请求?code=${vdata.code}", "#pdfSee");
count(); 
}; 
</script>

Copy after login

body fragment:

<body >
<div align=center id="beforeSee" width="100%" height="100%"> 
<p><span class="red" style="font-size:50px;">拼命加载中，请稍后</span></p> 
<p> 
<input type="text" id="chart" name="chart" size="46" style="font-family:Arial; font-weight:bolder; color:gray;background-color:white; padding:0px; border-style:none;"> 
<br> 
<input type="text" id="percent" name="percent" size=46 style="font-family:Arial; color:gray; text-align:center; border-width:medium; border-style:none;">
<script type="text/javascript">
</script>
</p> 
</div>
<div align=center id="pdfSee" style="display:none" width="100%" height="100%">
<p><span class="red" style="font-size:50px;">控件丢失，请重新加载</span></p>
</div>
</body>

Copy after login

The above is the fake loading animation effect generated by jQuery introduced by the editor. I hope it will be helpful to everyone
