iframe-reizer中的错误处理？

Question

I use iframe-resizer to insert content(jsf-pages) in iframe. So, how to detect that server responsed with 404 not found?

Is there some callback or other way to detect this?

Answer 1

 const iframeResizerOptions = {
    log: true,
    checkOrigin: true,
    initCallback: (iframe) => {
      if (iframe.contentDocument.getElementsByClassName("error-title").length > 0) {
        onError();
      } else {
        onLoad();
      }
    },
  };

You may use initCallback and get iframe from input parameter.
