Try:
var obj = example.split(\"/\"); obj[0];
سؤال
I want to use ScriptEngine of Java but I have some trouble with javascript split function like below:
ScriptEngineManager manager = new ScriptEngineManager();
ScriptEngine engine = manager.getEngineByName("javascript");
Bindings bindings = engine.createBindings();
bindings.put("example", "123/456/789");
String s1 = "var obj = example.split(\"/\"); print(obj[0]);";
Object result = engine.eval(s1, bindings);
System.out.println(result);
when I evaluate the script; this code prints "123null" because result is null. When I tried return statement instead of print like this:
String s1 = "var obj = example.split(\"/\"); return obj[0];";
throws an exception:
Exception in thread "main" javax.script.ScriptException: sun.org.mozilla.javascript.internal.EvaluatorException: invalid return (#1) in at line number 1
So how should I get the value of first index from this splitted native array?
