js 里面的keycode 鼠标滚轮的值是多少???
参考技术A 滚轮是1如果是event.keyCode的话,输出全是0
追问
不行哦。我就是想判断它是不是鼠标滚轮事件,然后去禁用滚轮,在某个时刻,我在去启动鼠标滚轮事件,就是想问问,如何禁用 和 启用鼠标的滚轮事件。 参考技术B document.onmousedown = function(event)
console.log(event.button);
滚轮是1
如果是event.keyCode的话,输出全是0

追答document.onmousewheel = function(event)
return false;

如果要使用组合键,则可以利用event.ctrlKey,event.shiftKey,event .altKey值为true或false,判断是否按下了ctrl键、shift键以及alt键。
例:event.ctrlKey=true && event.keycode=65
