Recently, the company’s website needs to count the pages from which users enter the registration page. At first, it is simply fetched on the server side by $_SERVER[‘HTTP_REFERER’] (PHP). However, it was found that many registered users did not have a referer value. Later, I checked to see that if I jumped in the window.location.href mode under IE, the referer value was null. And on the label < A> < / a> The inside skip referer will not be empty. Therefore, this IE problem can be solved by following the code:

function gotoUrl(url){
if(document.all){
var gotoLink = document.createElement('a');

gotoLink .href = url;

document.body.appendChild(gotoLink);

gotoLink .click();

}
else window.location.href = url;
}

The idea is to create a tag. A> , then set the url to jump to, and finally trigger the click event.
