在一个硬件项目上工作，我一步一步地尝试让这个确认窗口弹出，但无法弄清楚。我没有收到任何控制台错误，所以我假设我的代码只是在某个地方损坏了。

function processInput() {
var propertyWidth = 300;
var propertyHeight = 100;
var winLeft = ((screen.width - propertyWidth) / 2);
var winTop = ((screen.height - propertyHeight) / 2);
var winOptions = "width=300,height=100";
winOptions += ",left=" + winLeft;

window.open("confirm.htm", "confirm", winOptions);

function createEventListener() {
var submitButton = document.getElementById("submit");
if (submitButton.addEventListener) {
submitButton.addEventListener("click", processInput,
false);
} else if (submitButton.attachEvent) {
submitButton.attachEvent("onclick", processInput);

if (window.addEventListner) {
window.addEventListener("load", createEventListener, false);
} else if (window.attachEvent) {
window.attachEvent("onload", createEventListener);
}

将此代码移到 createEventListener 之外:
if (window.addEventListner) {
window.addEventListener("load", createEventListener, false);
} else if (window.attachEvent) {
window.attachEvent("onload", createEventListener);
}
