为什么这个函数在没有点击指定按钮的情况下被触发?我看了一些类似的问题,但没有一个处理这个代码结构(可能是我失踪的明显原因......).
Why does this function get fired without having clicked on the specified button? I had a look at a few similar problems but none deal with this code structure (might be obvious reason for this im missing...).
document.getElementById("main_btn").addEventListener("click", hideId("main");
function hideId(data) {
document.getElementById(data).style.display = "none";
console.log("hidden element #"+data);
}
你是直接调用它.
document.getElementById("main_btn").addEventListener("click", hideId("main");
你应该在回调中这样做.
You should do that in a callback.
document.getElementById("main_btn").addEventListener("click", function (){
hideId("main");
});
