Der Selenium -Treiber wartet nicht darauf, dass die Seite Java für mermaid.js lädt ⇐ Java

[Anonymous]

Ich möchte mermaid.js verwenden, um ein Flussdiagramm zu rendern. Ich möchte den Selenium -Treiber in Java verwenden, um den gerenderten HTML Dom zu lesen. Die HTML -Quelle wird jedoch gelesen, wenn das Rendering nicht vollständig ist. Wie kann ich es erreichen? Code ">

import mermaid from 'https://cdn.jsdelivr.net/npm/[email protected]/+esm'
const config = {
startOnLoad: true,
flowchart: { useMaxWidth: true, htmlLabels: true, curve: 'cardinal' },
securityLevel: 'loose',
};
mermaid.initialize(config);
