JSObject.eval() Java Method

Name

JSObject.eval() Java Method---evaluate a string of JavaScript code

Availability

Part of the netscape.javascript package included with Navigator 3.0

Synopsis

public Object eval(String s)

Arguments

s: A string that contains arbitrary JavaScript statements, separated by semicolons.

Returns

The JavaScript value of the last expression evaluated in s, converted to a Java object.

The eval() method of the Java JSObject class evaluates the JavaScript code contained in the String s in the context of the JavaScript object specified by the JSObject. The eval() method of the Java JSObject class behaves just like the eval() method of the JavaScript Object "class."

The argument s may contain any number of JavaScript statements, separated by semicolons; these statements will be executed in the order in which they appear. The return value of eval() is the value of the last statement or expression evaluated in s.
