调用document.write() [英] Invoking document.write()

问题描述

此代码不起作用:

<div class="pix"><div id="addTimestamp"></div></div>
<script type="text/javascript">
(function () {
    var date = new Date(), 
        timestamp = date.getTime(),
        newScript = document.createElement("script");

    newScript.type = 'text/javascript';
    newScript.src = 'someUrl=' + timestamp + '?';
    document.getElementById('addTimestamp').appendChild(newScript);
}())
</script>

动态脚本会添加 document.write(加载横幅广告的someCode).但是在Firebug中，我有一个错误:

The dynamic script adds document.write(someCode which loads banners). But in Firebug I have an error:

从异步加载的外部脚本中调用document.write()被忽略.

Invoking document.write() from asynchronously-loaded external script was ignored.

推荐答案

添加此内容:

newScript.async = false;

您的脚本需要同步加载才能使 document.write()正常工作(请参见

Your script needs to load synchronously for document.write() to work (see https://developer.mozilla.org/En/HTML/Element/Script#attr-async). As you have it now, the script will load whenever the browser has time for it - so you cannot know where your HTML from document.write() will be inserted. The browser decided to ignore your document.write() call to prevent worse issues.
