Method Detail

onScriptContextCreated

void onScriptContextCreated(ScriptContextEvent event)

Invoked when JavaScript context has been created. The event is invoked synchronously blocking JavaScript execution. Don't block current method execution for too long to avoid web page loading and displaying performance.

This callback is intened to allow you to inject JavaScript code into the page. You should not modify the DOM tree in this callback either via JavaScript or using JxBrowser DOM API. An attempt to remove the frame for which this callback is invoked from the DOM tree might lead to a crash of the Chromium process.

创建JavaScript上下文时调用。同步调用该事件以阻止JavaScript执行。不要太长时间阻塞当前方法的执行，以免网页加载和显示性能。该回调旨在允许您将JavaScript代码注入页面。您不应该通过JavaScript或使用JxBrowser DOM API修改此回调中的DOM树。尝试从DOM树中删除为其调用了此回调的框架可能会导致Chromium进程崩溃。
