目前我的页面： http: //www.sagu.edu/spec-home

特别是页脚形式。

我目前正在尝试访问电子邮件字段 Field121。

目前我有这个：

var trackcmp_email = wufooFormm73jde715tzew1.document.getElementById("form227").Field121.value;

但它显示错误说wufooFormm73jde715t

<div class="custom">
  <div id="wufoo-m73jde715tzew1">
    <iframe id="wufooFormm73jde715tzew1" class="wufoo-form-container" height="383" allowtransparency="true" frameborder="0" scrolling="no" style="width:100%;border:none" src="https://sagu.wufoo.com/embed/m73jde715tzew1/def/embedKey=m73jde715tzew1327047&amp;entsource=&amp;referrer=">&lt;a href="https://sagu.wufoo.com/forms/m73jde715tzew1/" title="html form"&gt;Fill out my Wufoo form!&lt;/a&gt;</iframe>

这是iframe我试图访问的：

<div id="wufoo-m73jde715tzew1"><iframe id="wufooFormm73jde715tzew1" class="wufoo-form-container" height="383" allowtransparency="true" frameborder="0" scrolling="no" style="width:100%;border:none" src="https://sagu.wufoo.com/embed/m73jde715tzew1/def/embedKey=m73jde715tzew1327047&amp;entsource=&amp;referrer=">&lt;a href="https://sagu.wufoo.com/forms/m73jde715tzew1/" title="html form"&gt;Fill out my Wufoo form!&lt;/a&gt;</iframe></div>

我正在尝试将 wufoo iframe 中的电子邮件字段用于此处找到的活动活动：

<script type="text/javascript">


var trackcmp_email = wufooFormm73jde715tzew1.document.getElementById("form227").Field121.value;
alert(trackcmp_email);
var trackcmp = document.createElement("script");
trackcmp.async = true;
trackcmp.type = 'text/javascript';
trackcmp.src = '//trackcmp.net/visit?actid=609412436&e='+encodeURIComponent(trackcmp_email)+'&r='+encodeURIComponent(document.referrer)+'&u='+encodeURIComponent(window.location.href);
var trackcmp_s = document.getElementsByTagName("script");
if (trackcmp_s.length) {
    trackcmp_s[0].parentNode.appendChild(trackcmp);
} else {
    var trackcmp_h = document.getElementsByTagName("head");
    trackcmp_h.length && trackcmp_h[0].appendChild(trackcmp);
}
</script>

您需要按如下方式引用 iFrame：

window.frames['myIFrame'].document.getElementById('myIFrameElemId');

所以在你的情况下：

window.frames['wufooFormm73jde715tzew1'].document.getElementById('form227')

请尝试下一个代码：

document.getElementById('wufooFormm73jde715tzew1').contentWindow.document.getElementById("form227")

它应该适用于嵌入式 iframe。但是，如果 iframe 中的页面是从不同的域（例如 google.com）加载的，您将无法执行此操作。这是因为浏览器的政策。
