如何将计时事件添加到事件侦听器

Question

I need to delay this by 3 seconds...

document.addEventListener("DOMContentLoaded", function(event) {
var x = VarPagesInChapter.getValue();
var y = Var_visitedPageCount.getValue();
var progress = Math.round(y/x*100);
document.getElementById('pct').innerHTML = progress+'%';
document.getElementById('radial').classList.add('p'+progress);
});

You need the setTimeout() function:

 document.addEventListener("DOMContentLoaded", function(event) { console.log( "Loaded at " + performance.now() ); setTimeout(function() { //Your code console.log( "I'm ready at " + performance.now() ); }, 3000); // 3000 milliseconds = 3 sec });
