JavaScript run function keydown

javascriptonkeydown

提问by Jeremy Karlsson

I cant find an answer to this that I understand. I want with JavaScript (not jQuery) to make it so if the with the id boxFilm is visible and I click on "SPACE" (keycode 32), the function togglep(); runs.

我找不到我理解的答案。我想使用 JavaScript(不是 jQuery)来实现,如果 id 为 boxFilm 的可见并且我单击“SPACE”(键码 32),则函数 togglep(); 运行。

How do I do this? I've tried many things but haven't succeeded :(

我该怎么做呢?我尝试了很多东西,但没有成功:(

function togglep(){
    alert("Hi");
}

document.body.onkeydown = function(event){
    event = event || window.event;
    var keycode = event.charCode || event.keyCode;
    if(keycode === 32){
        togglep();
    }
}
