描述

Same situation as in closed issue https://github.com/vbauer/manet/issues/34

It is an AngularJs app that uses C3js to build SVG charts. The page has no errors when loading on the browser. Tried both phantomjs and phantomjs2 (with 2 the delay option doesn't seem to by applied).

In the screenshot I see the basic layout (static assets) of the page, but not the dynamic/async content. Neither the angular rendered parts, nor the generated SVGs are present in the screenshot.

Tried with large delays (20000) even though the page normally loads in low single digit seconds. No luck either.

研究方向
Investigate how manet captures screenshots, particularly the handling of async content. Look at the PhantomJS script used for rendering. Consider whether a custom callback or waitForAngularJS pattern is needed. Check closed issue #34 for previous discussions. The solution may involve modifying the rendering timeout or injecting a script to signal when async rendering completes.
