正如 eicto 通过评论所建议的那样,jquery 可用于在就绪事件中填充 iframe。为了将 iframe 的高度调整为内容的高度,必须应用一些肮脏的技巧,但我最终使用的代码或多或少是:
HTML
<!-- IMPORTANT! Do not add src or srcdoc -->
<!-- NOTICE! Add border:none to get a more "seamless" integration -->
<iframe style="border:none" scrolling="no" id="myIframe">
Iframes not supported on your device
</iframe>
JS
// Wait until iFrame is ready (body is then available)
$('#myIframe').ready(function() {
var externalHtml = '<p>Hello World!</p>';
// Find the body of the iframe and set its HTML
// Add a wrapping div for height hack
// Set min-width on wrapping div in order to get real height afterwords
$('#myIframe').contents().find('body')
.html('<div id="iframeContent" style="min-width:'+$('body').width()+'px">'
+externalHtml
+'</div>'
);
// Let the CSS load before getting height
setTimeout(function() {
// Set the height of the iframe to the height of the content
$('#myIframe').css('height',
$('#myIframe').contents()
.find('#iframeContent').height() + 'px'
);
},50);
});
