A few days ago, I saw an expert writing a routing using js in the yard. There was a line of code that I didn’t know what was going on. Then I wrote one myself. The writing was relatively rough. I think the object-oriented thinking It’s all a mess, but the function is implemented.

<!DOCTYPE html>
<html lang="en">
<head>
    <meta charset="UTF-8">
    <title>js实现路由</title>
</head>
<body>
    < a href=" " >white</ a>
    < a href="#/green" >green</ a>
    < a href="#/blue" >blue</ a>
    < a href="#/yellow" >yellow</ a>
</body>
</html>

<script>

    <span style="color: #0000ff;">function</span><span style="color: #000000;"> Route(){
    }
    Route.prototype.open</span>=<span style="color: #0000ff;">function</span><span style="color: #000000;">(route,callback){
        </span><span style="color: #0000ff;">var</span> arr=<span style="color: #000000;">{};
        arr[route]</span>=<span style="color: #000000;">callback;

        window.addEventListener(</span>'hashchange',<span style="color: #0000ff;">function</span><span style="color: #000000;">(){
