Please help me to sort out this issue.

Many questions are asked referencing this kind of issues. The ScriptException is raised because you have a syntactical error in your javascript. Most browsers manage to interpret the JS even with some kind of errors but HtmlUnit is a bit inflexible in that sense.

Your options are:

1. Correct JS code
2. Disable JS in the WebClient
3. Don't use HtmlUnit. Use a different framework with better JS support such as PhantomJS (note it is not a Java-based framework)

回答2:

I had the same error with the liveperson mTag.js

The problem is with the compacted mTag.js response.

There are several workaround:

1. Replace the compacted mTag.js with a clear one (requires LivePerson support)
2. Work with a 'real' Selenium WebDriver (Firefox Driver or similar)

回答3:

_webClient.getOptions().setThrowExceptionOnScriptError(false); 

works in this incorrect JS scenario.
