推荐答案
我认为您无法从此处删除条目，因为正在使用 JMeter类路径中的可用脚本引擎.
I don't think you will be able to remove entries from there as the drop down is being populated on-the-fly using ScriptEngineManager.getEngineFactories() method which performs discovery of available scripting engines in JMeter Classpath.
关于使用js或javascript的哪种语言，答案为无.建议使用 Groovy语言在JMeter测试中将任何形式的脚本用作行为良好的Groovy脚本可以被编译和缓存，因此它们的性能将非常类似于普通" Java代码，而每次调用其他脚本语言时都会对其进行解释，因此当涉及高负载时，使用JavaScript的JSR223测试元素可能会成为性能瓶颈，并且毁了你的测试.
With regards which language to use js or javascript the answer is none. It is recommended to use Groovy language for any form of scripting in JMeter tests as well-behaved Groovy scripts can be compiled and cached therefore their performance will be pretty like to "normal" Java code while other scripting languages are being interpreted each time they are being called so when it comes to high loads your JSR223 test element using JavaScript might become a performance bottleneck and ruin your test.
