Expand description

Evaluates a string of JavaScript.

  • ctx: The execution context to use.
  • script: A JSStringRef containing the script to evaluate.
  • thisObject: The object to use as this, or NULL to use the global object as this.
  • sourceURL: A JSStringRef containing a URL for the script’s source file. This is used by debuggers and when reporting exceptions. Pass NULL if you do not care to include source file information.
  • startingLineNumber: An integer value specifying the script’s starting line number in the file located at sourceURL. This is only used when reporting exceptions. The value is one-based, so the first line is line 1 and invalid values are clamped to 1.
  • exception: A pointer to a JSValueRef in which to store an exception, if any. Pass NULL if you do not care to store an exception.

The JSValueRef that results from evaluating script, or NULL if an exception is thrown.
