我希望将onclick,onkeyup绑定在一起并找出下面的原生JS版本。有人可以帮忙吗?
on("click keyup", ".searchButton",function(){
// code here
});

function addEvents(elm, events, handler){
for(var i = 0 ;i< events.length; i++){
elm.addEventListener( events[i] ,handler ,false);
}
}
您必须将事件名称放在像var ev = ['click','keyup'];

本机解决方案可以使用具有className检查的全局侦听器,如:
function dosomething(ev){
var tgt = ev.target;
var log = document.getElementById('log');
if( !tgt.classList.contains('something') ) {
log.innerHTML += 'ignoring<br>';
return true
}
log.innerHTML += tgt.tagName + ' ' + tgt.className + '<br>';
}
document.body.addEventListener('click',dosomething);
document.body.addEventListener('keyup',dosomething);
<button type="button" class="something">something</button>
<button type="button">not something</button>
<input type="text" class="something" placeholder="something">
<input type="text" placeholder="not something">
<div id="log"></div>
