String.split doesn't work #15

Open GoogleCodeExporter opened 8 years ago

GoogleCodeExporter commented 8 years ago 
String.split doesn't work. In JsObject, the STRING_PROTOTYPE does not
define the method name and parameter count.

In the actual implementation in evalNative, there's also a bug if the
caller doesn't not specify the "limit." In that case, an empty JsArray is
returned and instead it should split the whole string.

This should fix it:

JsObject.cs

public static final JsObject STRING_PROTOTYPE = 
....
.addVar("slice", new JsFunction(ID_SLICE, 2))
.addVar("split", new JsFunction(ID_SPLIT, 2))
.addVar("substring", new JsFunction(ID_SUBSTRING, 2))
...

evalNative(int index, JsArray stack, int sp, int parCount)
{
  ...
  case ID_SPLIT:
  {
    ...
    double limit = stack.isNull(sp + 3) ? Double.NaN : stack.getNumber(sp + 3);
    ...
