将事件侦听器添加到 html 绘图

Question

所以我需要一些快速帮助，下面是我的简单 html 绘图代码，如您所见，当屏幕加载时绘图会自动启动，相反我想添加一个事件侦听器，它将允许用户当他点击屏幕时动画开始，当他再次点击时动画停止，等等我得到了逻辑，但我无法正确实现语法，所以我在代码片段下方添加了供大家查看。任何类型的建议或帮助将不胜感激！

 // run on load

//resize on resizeEnd function
$(window).bind('resizeEnd', function() {

Answer 1

只需删除加载时对函数的调用：

// run on load
sol86();

并添加此事件：

window.onclick = function(event) {
    sol86();
}

或（Jquery样式）

$(window).click(function(event) {
    sol86();
});
