2021年6月14日利用localStorage记录鼠标点击次数（支持页面刷新后继续统计）

    <p><button onclick="clickCounter()" type="button">点我!</button></p>
    <div id="result"></div>
    
    
      
      
    

    var result = document.getElementById("result");
    function clickCounter() {
    if (localStorage.clickcount) localStorage.clickcount = Number(localStorage.clickcount) + 1
    else localStorage.clickcount = 1;
    result.innerHTML = "你在按钮上已经点击了 " + localStorage.clickcount + "次。";
    }
