html显示console未定义,java-Htmlunit ScriptException“控制台”未定义

我正在使用htmlunit 2.9并在Java脚本解析中由于以下异常中的控制台而导致脚本异常

function debug(o){

if (console && console.log){

console.log(o)

}

};

堆栈跟踪

如果我尝试在firefox上指定的页面工作正常,那么我已经尝试了v 3.6和9.0.1.

我也尝试设置setThrowExceptionOnScriptError(false)以避免异常,但引擎停止运行,或者在收到错误后不解析javascript.

javascript引擎可以通过任何方式理解javascript中的控制台吗？
