How to refresh or reload a page with timeout in javascript or jquery

问题

How can I refresh or reload a page with timeout in javascript or jquery only when

• a specific class is visible or
• img is not found

i found this https://stackoverflow.com/a/14787543/7051635 but there is no timeout and when i'm in front of an omg not found, nothing happened.

Use the setTimeout() global method to create a timer. This will reload the page after 5000 milliseconds (5 seconds):

 setTimeout(function(){ location.reload(); }, 5000);

This code can be added to any event you need it to. So, for example:

var theDiv = document.querySelector("div");

// When the div is clicked, wait 5 seconds and then hide it.
theDiv.addEventListener("click", function(){
   setTimeout(function(){ 
     theDiv.classList.add("hide"); 
   }, 5000);
});

.hide { display:none; }

<div>Now you see me.</div>
