本文整理了Java中com.google.gwt.core.client.JavaScriptException类的一些代码示例，展示了JavaScriptException类的具体用法。这些代码示例主要来源于Github/Stackoverflow/Maven等平台，是从一些精选项目中提取出来的代码，具有较强的参考意义，能在一定程度帮忙到你。JavaScriptException类的具体详情如下：
包路径：com.google.gwt.core.client.JavaScriptException
类名称：JavaScriptException

JavaScriptException介绍

[英]Any JavaScript exceptions occurring within JSNI methods are wrapped as this class when caught in Java code. The wrapping does not occur until the exception passes out of JSNI into Java. Before that, the thrown object remains a native JavaScript exception object, and can be caught in JSNI as normal.

The return value of #getStackTrace() may vary between browsers due to variations in the underlying error-reporting capabilities. When possible, the stack trace will be the stack trace of the underlying error object. If it is not possible to accurately report a stack trace, a zero-length array will be returned. In those cases where the underlying stack trace cannot be determined, #fillInStackTrace() can be called in the associated catch block to create a stack trace corresponding to the location where the JavaScriptException object was created.

try { 
nativeMethod(); 
} catch (JavaScriptException e) { 
if (e.getStackTrace().length == 0) { 
e.fillInStackTrace(); 
} 
}

[中]在Java代码中捕获时，JSNI方法中发生的任何JavaScript异常都被包装为此类。直到异常从JSNI传递到Java中，包装才会发生。在此之前，抛出的对象仍然是一个本机JavaScript异常对象，可以在JSNI中正常捕获。
#getStackTrace（）的返回值可能因浏览器而异，这是由于底层错误报告功能的不同。如果可能，堆栈跟踪将是底层错误对象的堆栈跟踪。如果无法准确报告堆栈跟踪，将返回零长度数组。在无法确定底层堆栈跟踪的情况下，可以在关联的catch块中调用#fillInStackTrace（），以创建与创建JavaScriptException对象的位置相对应的堆栈跟踪。

try { 
nativeMethod(); 
} catch (JavaScriptException e) { 
if (e.getStackTrace().length == 0) { 
e.fillInStackTrace(); 
} 
}
