js怎么点击按钮后重复相同的事件和按钮并继承上次的函数

Question

<button onclick="a()">横砍</button>
<button onclick="b()">竖劈</button>
<button onclick="c()">横砍</button>
<button onclick="d()">竖劈</button>

//    var s = Math.random();
//s = Math.ceil(s * 4);
//document.write(s);



var x;
var x2
w = 15;
w = 4;
h = 10
var number = Math.random();
number = Math.ceil(number * 4);
document.write(number);

重复下面的按钮和事件并继承上次的函数值，救命啊！！

    function a() {
        var s = Math.random();
s = Math.ceil(s * 4);
document.write(s);
        if (number == 1) {
            
            w = w - 3
                 }
                }
    function b() {
        if (number == 2) {
            alert("bb")
        }
    }
    function c() {
        if (number == 3) {
            alert("cc")
        }
    }
    function d() {
        if (number == 4) {
            alert("dd")
        }
    }

不太清楚你的描述。要重复执行某个函数，可以用setInterval按照指定延时（单位毫秒）可以重复执行，继承上次的值可用全局变量。还有个问题就是文档流关闭后不要使用document.write输出内容，会覆盖当前页面的内容。

<button onclick="setInterval(a, 1000);this.disabled=1">横砍</button>
<button onclick="b()">竖劈</button>
<button onclick="c()">横砍</button>
<button onclick="d()">竖劈</button>
<div id="log"></div>
<script>

    var x;
    var x2
    w = 15;
    w = 4;
    h = 10
    var number = Math.random();
    number = Math.ceil(number * 4);
    document.write(number);

    function a() {
        var s = Math.random();
        s = Math.ceil(s * 4);
        //document.write(s);
        log.innerHTML += s + ',';
        if (number == 1) {
            w = w - 3
        }
    }
    function b() {
        if (number == 2) {
            alert("bb")
        }
    }
    function c() {
        if (number == 3) {
            alert("cc")
        }
    }
    function d() {
        if (number == 4) {
            alert("dd")
        }
    }


</script>
