javascript - window.addEventListener中的延迟

我想在延迟一段时间后调用onMessageReceived。

window.addEventListener("message", onMessageReceived);

function onMessageReceived(event)
{
    var messageData = JSON.parse(event.data);

    if (messageData.type === "panelExpanded")
    {
        expandButton.style.display = 'none';
    }
}

当接收到的数据为“ panelExpanded”时，我想隐藏expandButton

我要延迟onMessageRecieved方法。我尝试了setInterval和setTimeout，但没有这项工作。

setTimeout(window.addEventListener("message", onMessageReceived), 3000);
window.addEventListener ('message', function () {
    setTimeout (onMessageReceived, 3000);
}, false);

setInterval(window.addEventListener("message", onMessageReceived), 3000);
window.addEventListener ('message', function () {
    setInterval (onMessageReceived, 3000);
}, false);

如何添加延迟？帮助将不胜感激。提前致谢

最佳答案

你有这样尝试过吗？

window.addEventListener("message", onMessageReceived);

function onMessageReceived(event)
{
    setTimeout(function(){
        var messageData = JSON.parse(event.data);

        if (messageData.type === "panelExpanded")
        {
            expandButton.style.display = 'none';
        }
    },3000);
}
