Question

我有另一家公司提供的嵌入式iframe用于事件注册。

无论我尝试什么，都无法使用鼠标滚轮使iframe滚动。如果将光标放在表单上，它将不会滚动。如果光标位于iframe之外，则位于滚动条附近，那么它将起作用。

提供的原始代码没有设置溢出样式。我添加了它，并尝试了溢出：滚动和溢出：自动，但无济于事。

这是给我的完整代码：

var userOffset = new Date().getTimezoneOffset();
var uagent = navigator.userAgent.toLowerCase();
var safariLink = document.getElementById("safari-link");
var iFrame = document.getElementById("iframeResizer0");
if (/safari/.test(uagent) && !/chrome/.test(uagent)) {
  safariLink.style.display = "inline";
  safariLink.setAttribute('href', safariLink.getAttribute('href') + '&Offset=' + userOffset);
  iFrame.style.display = "none";
  document.getElementById("iframe-loading").style.display = "none";
} else {
  safariLink.style.display = "none";
  iFrame.style.display = "inline";
  iFrame.setAttribute('src', iFrame.getAttribute('src') + '&Offset=' + userOffset);
}
iFrameResize({
  autoResize: false,
  log: true, // Enable console logging
  enablePublicMethods: true, // Enable methods within iframe hosted page
  checkOrigin: false,
  resizedCallback: function(messageData) { // Callback fn when resize is received
    document.getElementById("iframe-loading").style.display = "none";
  }
});

#iframe-loading {
  width: 100%;
  text-align: center;
}

<div id="iframe-loading"><img src="https://tradeshow.perenso.net/registration/content/images/ajax-loader.gif" /></div>

<iframe src="https://tradeshow.perenso.net/registration/embedded/index/CASAIMPORTSSEP18?RegType=CUSTOMER" style="border: 0; width: 100%; overflow:auto;" id="iframeResizer0" scrolling="yes"></iframe>

<div style="text-align: center;">

  <a href="https://tradeshow.perenso.net/registration/embedded/index/CASAIMPORTSSEP18?RegType=CUSTOMER" id="safari-link" target="_blank" class="button icon icon-after fa-chevron-right">Open Registration Form</a></li>


</div>

感谢您的帮助。

Answer 2

您需要将scrolling="yes"属性添加到 HTML 中的<iframe>标记中。像这样：

<iframe src="https://tradeshow.perenso.net/registration/embedded/index/CASAIMPORTSSEP18?RegType=CUSTOMER" style="border: 0; width: 100%; overflow:auto;" id="iframeResizer0" scrolling="yes"></iframe>

嵌入式iframe无法滚动
