XMLHttpRequest无法加载谷歌表单

Question

我的页面上有以下表格：

    <iframe id="hidden_iframe" name="hidden_iframe" onload=
"if(submitted) {window.location='thank-you.html';}" style=
"display:none;"></iframe>

<div class="form-wrap" id="newsletter">
    <form action=
    "https://docs.google.com/forms/d/1ckysxoBGBaN_sKGFVda2D0cxR0muzhm6LeUb3PDfId0/formResponse"
    class="newsletter-form" id="newsletter-form" method="post" name=
    "newsletter-form" onsubmit="submitted=true;" target="hidden_iframe">
        <input class="ss-q-short" dir="auto" id="entry_1476137342" name=
        "entry.1476137342" required="" title="Must be a valid email address"
        type="email" value=""> <input name="draftResponse" type="hidden" value=
        "[,,&quot;1794978808793485775&quot;]"> <input name="pageHistory" type=
        "hidden" value="0"> <input name="fbzx" type="hidden" value=
        "1794978808793485775"> <input id="ss-submit" name="submit" type=
        "submit" value="Submit">
    </form>
</div>

正如您所看到的，此表单基本上是一个Google表单，在提交时应该重定向到thank-you.html页面。基本上这肯定应该工作，但我进入chrome控制台：

XMLHttpRequest cannot load https://docs.google.com/forms/d/1ckysxoBGBaN_sKGFVda2D0cxR0muzhm6LeUb3PDfId0/formResponse. No 'Access-Control-Allow-Origin' header is present on the requested resource. Origin 'null' is therefore not allowed access.

有什么建议吗？

我非常感谢你的回答！
