Evaluate Expression. - 2. Call GetValue(Result(1)). - 3. Call ToObject(Result(2)). - 4. Add Result(3) to the front of the scope chain. - 5. Evaluate Statement using the augmented scope chain from step 4. - 6. Remove Result(3) from the front of the scope chain. - 7. Return Result(5). - - Discussion - Note that no matter how control leaves the embedded Statement, whether - normally or by some form of abrupt completion, the scope chain is always - restored to its former state. - - Author: christine@netscape.com - Date: 12 november 1997 -*/ - -var SECTION = "12.10-1"; -var VERSION = "ECMA_1"; -startTest(); -var TITLE = "The with statement"; - -writeHeaderToLog( SECTION + " "+ TITLE); - - -// although the scope chain changes, the this value is immutable for a given -// execution context. - -new TestCase( SECTION, - "with( new Number() ) { this +'' }", - GLOBAL, - eval("with( new Number() ) { this +'' }") ); - -// the object's functions and properties should override those of the -// global object. - -new TestCase( - SECTION, - "var MYOB = new WithObject(true); with (MYOB) { parseInt() }", - true, - eval("var MYOB = new WithObject(true); with (MYOB) { parseInt() }") ); - -new TestCase( - SECTION, - "var MYOB = new WithObject(false); with (MYOB) { NaN }", - false, - eval("var MYOB = new WithObject(false); with (MYOB) { NaN }") ); - -new TestCase( - SECTION, - "var MYOB = new WithObject(NaN); with (MYOB) { Infinity }", - Number.NaN, - eval("var MYOB = new WithObject(NaN); with (MYOB) { Infinity }") ); - -new TestCase( - SECTION, - "var MYOB = new WithObject(false); with (MYOB) { }; Infinity", - Number.POSITIVE_INFINITY, - eval("var MYOB = new WithObject(false); with (MYOB) { }; Infinity") ); - - -new TestCase( - SECTION, - "var MYOB = new WithObject(0); with (MYOB) { delete Infinity; Infinity }", - Number.POSITIVE_INFINITY, - eval("var MYOB = new WithObject(0); with (MYOB) { delete Infinity; Infinity }") ); - -// let us leave the with block via a break. - -new TestCase( - SECTION, - "var MYOB = new WithObject(0); while (true) { with (MYOB) { Infinity; break; } } Infinity", - Number.POSITIVE_INFINITY, - eval("var MYOB = new WithObject(0); while (true) { with (MYOB) { Infinity; break; } } Infinity") ); - - -test(); - -function WithObject( value ) { - this.prop1 = 1; - this.prop2 = new Boolean(true); - this.prop3 = "a string"; - this.value = value; - - // now we will override global functions - - this.parseInt = new Function( "return this.value" ); - this.NaN = value; - this.Infinity = value; - this.unescape = new Function( "return this.value" ); - this.escape = new Function( "return this.value" ); - this.eval = new Function( "return this.value" ); - this.parseFloat = new Function( "return this.value" ); - this.isNaN = new Function( "return this.value" ); - this.isFinite = new Function( "return this.value" ); -} |
