Question

我的网站上有两个脚本，使用Onclick和Style null会产生jscript错误。我该如何解决这个问题？

1

<script>
document.getElementById("chooser-image").onclick = function () {
    Dropbox.choose({
        linkType: "direct",
        extensions: ['.pdf', '.jpg', '.zip'],
        success: function(files) {
            var linkTag = document.getElementById('link');
            linkTag.href = files[0].link;
            linkTag.textContent = files[0].link;
        }
    });
};

错误： TypeError：无法设置属性＆＃39; onclick＆＃39;为null http://www.domain.dk/kontakt-os:1019

Answer 1

您的第一个脚本应该在关闭</body>之前，或<div id="chooser-image" />之后或document.onload = function{}之内。对于第二个代码段：它应位于<body>标记之间的<head>，不是内。您的错误表明<div id="livezilla_tracking" />根本不存在。

脚本Onclick使jscript错误
