Question

伙计我不知道如何在javascript中添加一些时间间隔。你知道如何在更改图像的src之前添加一些时间。我从W3schools

获取此代码

＆＃13;

document.getElementById("image").src = "http://www.w3schools.com/js/landscape.jpg";

＆＃13;

<!DOCTYPE html>
<html>
<body>

<img id="image" src="http://www.w3schools.com/js/smiley.gif" width="160" height="120">

<p>The original image was smiley.gif, but the script changed it to landscape.jpg</p>

</body>
</html>

＆＃13;

setTimeout(function() {
                      document.getElementById("image").setAttribute("src", "http://www.w3schools.com/js/landscape.jpg");
                  }, 5000);

<img id="image" src="http://www.w3schools.com/js/smiley.gif" width="160" height="120">

<p>The original image was smiley.gif, but the script changed it to landscape.jpg</p>
