使用 CefSharp 在 c# 中执行脚本时出错

Question

I try to use the next

chromeBrowser.ExecuteScriptAsync("$('#user').setAttribute('value', 'usuario');");

I received the message:

Uncaught ReferenceError: $ is not defined

When I use the console browser of Chrome it's successfully executed.

Answer 1

You should execute your scripts after your dependencies has been loaded. On browser.LoadingStateChanged event, probably would be the best place for that.

Look at https://github.com/cefsharp/CefSharp/wiki/General-Usage#when-can-i-start-executing-javascript for more information.
