Expand description

Evaluates a string of JavaScript.

Parameter ctx: The execution context to use.

Parameter script: A JSString containing the script to evaluate.

Parameter thisObject: The object to use as “this,” or NULL to use the global object as “this.”

Parameter sourceURL: A JSString 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.

Parameter 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.

Parameter 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.

Returns: The JSValue that results from evaluating script, or NULL if an exception is thrown.
