将img标签的src设置为javascript函数的结果

Question

我有一个函数getImgurUrl(),我希望它返回的是img标记的src值.

我怎样才能做到这一点？

我的功能:

function getImgurUrl() {
    //get imgur url for current image
    var cookieArray = document.cookie.split(";");
    var encodedURL = cookieArray[2].split("=");
    var decodedURL = decodeURIComponent(encodedURL[1]);
    return decodedURL;
}

和img标签:

<img id="image" name="image" src=""  alt="If you're seeing this something is wrong.">

Answer 1

window.onload = function() {
    document.getElementById("image").src = getImgurUrl();
};
