Evaluate AdditiveExpression. 1.22 + 2. Call GetValue(Result(1)). 1.23 + 3. Evaluate MultiplicativeExpression. 1.24 + 4. Call GetValue(Result(3)). 1.25 + 5. Call ToPrimitive(Result(2)). 1.26 + 6. Call ToPrimitive(Result(4)). 1.27 + 7. If Type(Result(5)) is String or Type(Result(6)) is String, go to step 12. 1.28 + (Note that this step differs from step 3 in the algorithm for comparison 1.29 + for the relational operators in using or instead of and.) 1.30 + 8. Call ToNumber(Result(5)). 1.31 + 9. Call ToNumber(Result(6)). 1.32 + 10. Apply the addition operation to Result(8) and Result(9). See the discussion below (11.6.3). 1.33 + 11. Return Result(10). 1.34 + 12. Call ToString(Result(5)). 1.35 + 13. Call ToString(Result(6)). 1.36 + 14. Concatenate Result(12) followed by Result(13). 1.37 + 15. Return Result(14). 1.38 + 1.39 + Note that no hint is provided in the calls to ToPrimitive in steps 5 and 6. 1.40 + All native ECMAScript objects except Date objects handle the absence of a 1.41 + hint as if the hint Number were given; Date objects handle the absence of a 1.42 + hint as if the hint String were given. Host objects may handle the absence 1.43 + of a hint in some other manner. 1.44 + 1.45 + This test does not cover cases where the Additive or Mulplicative expression 1.46 + ToPrimitive is string. 1.47 + 1.48 + Author: christine@netscape.com 1.49 + Date: 12 november 1997 1.50 +*/ 1.51 +var SECTION = "11.6.1-1"; 1.52 +var VERSION = "ECMA_1"; 1.53 +startTest(); 1.54 + 1.55 +writeHeaderToLog( SECTION + " The Addition operator ( + )"); 1.56 + 1.57 +// tests for "MyValuelessObject", where the value is 1.58 +// set in the object's prototype, not the object itself. 1.59 + 1.60 +new TestCase( SECTION, 1.61 + "var EXP_1 = new MyValuelessObject(true); var EXP_2 = new MyValuelessObject(false); EXP_1 + EXP_2", 1.62 + 1, 1.63 + eval("var EXP_1 = new MyValuelessObject(true); var EXP_2 = new MyValuelessObject(false); EXP_1 + EXP_2") ); 1.64 + 1.65 +new TestCase( SECTION, 1.66 + "var EXP_1 = new MyValuelessObject(new Boolean(true)); var EXP_2 = new MyValuelessObject(new Boolean(false)); EXP_1 + EXP_2", 1.67 + "truefalse", 1.68 + eval("var EXP_1 = new MyValuelessObject(new Boolean(true)); var EXP_2 = new MyValuelessObject(new Boolean(false)); EXP_1 + EXP_2") ); 1.69 + 1.70 +// tests for "MyValuelessObject", where the value is 1.71 +// set in the object's prototype, not the object itself. 1.72 + 1.73 + 1.74 +new TestCase( SECTION, 1.75 + "var EXP_1 = new MyValuelessObject(100); var EXP_2 = new MyValuelessObject(-1); EXP_1 + EXP_2", 1.76 + 99, 1.77 + eval("var EXP_1 = new MyValuelessObject(100); var EXP_2 = new MyValuelessObject(-1); EXP_1 + EXP_2") ); 1.78 + 1.79 +new TestCase( SECTION, 1.80 + "var EXP_1 = new MyValuelessObject(new Number(100)); var EXP_2 = new MyValuelessObject(new Number(-1)); EXP_1 + EXP_2", 1.81 + "100-1", 1.82 + eval("var EXP_1 = new MyValuelessObject(new Number(100)); var EXP_2 = new MyValuelessObject(new Number(-1)); EXP_1 + EXP_2") ); 1.83 + 1.84 +new TestCase( SECTION, 1.85 + "var EXP_1 = new MyValuelessObject( new MyValuelessObject( new Boolean(true) ) ); EXP_1 + EXP_1", 1.86 + "truetrue", 1.87 + eval("var EXP_1 = new MyValuelessObject( new MyValuelessObject( new Boolean(true) ) ); EXP_1 + EXP_1") ); 1.88 + 1.89 +test(); 1.90 + 1.91 +function MyProtoValuelessObject() { 1.92 + this.valueOf = new Function ( "" ); 1.93 + this.__proto__ = null; 1.94 +} 1.95 + 1.96 +function MyProtolessObject( value ) { 1.97 + this.valueOf = new Function( "return this.value" ); 1.98 + this.__proto__ = null; 1.99 + this.value = value; 1.100 +} 1.101 + 1.102 +function MyValuelessObject(value) { 1.103 + this.__proto__ = new MyPrototypeObject(value); 1.104 +} 1.105 +function MyPrototypeObject(value) { 1.106 + this.valueOf = new Function( "return this.value;" ); 1.107 + this.toString = new Function( "return (this.value + '');" ); 1.108 + this.value = value; 1.109 +} 1.110 + 1.111 +function MyObject( value ) { 1.112 + this.valueOf = new Function( "return this.value" ); 1.113 + this.value = value; 1.114 +}
