按下空格键后执行JS代码 [英] Execute JS code after pressing the spacebar

问题描述

这是我在JavaScript中的代码:

this is my code in JavaScript:

var changeIdValue =  function(id, value) {
document.getElementById(id).style.height = value;
};

document.getElementById ("balklongwaarde").addEventListener("click", function(){ changeIdValue("balklongwaarde", "60px")});

document.getElementById ("balklevensverwachting").addEventListener("click", function(){ changeIdValue("balklevensverwachting", "60px")});

document.getElementById ("balkhart").addEventListener("click", function(){ changeIdValue("balkhart", "60px")});

document.getElementById ("balklever").addEventListener("click", function(){ changeIdValue("balklever", "60px")});

document.getElementById("balkhersenen").addEventListener("click", function(){ changeIdValue("balkhersenen", "60px")});

我想在按下按键后执行此代码....

I want to execute this code after press on keyup....

有人知道怎么做吗?

推荐答案

document.body.onkeyup = function(e){
    if(e.keyCode == 32){
        //your code
    }
}

这将在您按下空格键后执行.

This will be executed after you hit spacebar.
