经过三天的研究和反复试验，我无法获取iframe或其内容来触发调整大小事件，因此无法调用调整大小函数。如果我使用... trigger(“resize”);要手动触发调整大小事件，我的调整大小函数将被调用并起作用。 iframe中加载的页面与包含iframe的页面位于同一个域(http://localhost:81/curlExample/)。最终，iframe中的页面将由php curl方法提供，但是我想使其首先工作。

调整浏览器窗口的大小并导致iframe调整大小时，如何触发resize事件？
谢谢您的帮助!
iframe页面
<!DOCTYPE html>

<script src="http://ajax.googleapis.com/ajax/libs/jquery/1.11.1/jquery.min.js"></script>
<script>
$(document).ready(function(){
function setResize()
{
window.alert("Hello");
var iframeRef = document.getElementById('displayframe');
$(iframeRef).on("resize", function(){
var xExp = 0;
window.alert("Resize event fired.");
});
}
$('#displayframe').load(function()
{
alert("Hello from iFrame. Load event fired.");
var myStallTime = setTimeout(setResize, 3000);
});
});

</html>最佳答案
<iframe>元素将永远不会触发大小调整事件，例如<img>或<div>。您必须从window获取此事件。由于您的iframe文档与父文档来自同一来源，因此您可以访问其contentWindow和其他任何属性。
因此，请尝试以下操作:
var iframeWin = document.getElementById('displayframe').contentWindow;
$(iframeWin).on('resize', function(){ ... });
我仅使用DOM的
addEventListener 做到了。var iframeWin = document.getElementById('displayframe').contentWindow;
iframeWin.addEventListener('resize', function(){ ... });
