本文整理了Java中org.mozilla.javascript.Script类的一些代码示例，展示了Script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。Script类的具体详情如下：
包路径：org.mozilla.javascript.Script
类名称：Script

Script介绍

[英]All compiled scripts implement this interface.

This class encapsulates script execution relative to an object scope.
[中]所有编译的脚本都实现了这个接口。
此类封装相对于对象范围的脚本执行。

代码示例

jsscope = jscx.initStandardObjects( null, false );
try {
 jscx.setOptimizationLevel( Integer.valueOf( transMeta.environmentSubstitute( optimizationLevel ) ) );
} catch ( NumberFormatException nfe ) {
 error_message =
  Scriptable jsR = Context.toObject( jsScripts[i].getScript(), jsscope );
  jsscope.put( jsScripts[i].getScriptName(), jsscope, jsR );
   jsscript.exec( jscx, jsscope );
