Click event listener works in Safari in OSX but not in iOS

问题

I'm making a web app and I want to click on an element and handle the click in one long click event handler. I'm testing in Safari. The following works fine in Safari on my Mac but not in iOS:

<html>
    <head>
        <script>
            window.addEventListener("click",function (event) {
                alert('hi');
            });
        </script>
    </head>
    <body>
        <div style="width: 100%; height: 100%; background: black;">
        </div>
    </body>
</html>

Why does this work in the OSX version of Safari but not in iOS?

回答1:

This code should work cross-browser:

function Subscribe(event, element, func) {
    if (element.addEventListener) {
        element.addEventListener(event, func, false);
    } else if (element.attachEvent) {
        element.attachEvent("on" + event, func);
    } else {
        element['on' + event] = func;
    }
}

function func () {
    alert('hi');
}

Subscribe('click', window, func);
