However, 1.21 + the language permits the function to be invoked with some other number 1.22 + of arguments. The behavior of a function when invoked on a number of 1.23 + arguments other than the number specified by its length property depends 1.24 + on the function. 1.25 + 1.26 + 15.3.5.2 prototype 1.27 + The value of the prototype property is used to initialize the internal [[ 1.28 + Prototype]] property of a newly created object before the Function object 1.29 + is invoked as a constructor for that newly created object. 1.30 + 1.31 + 15.3.5.3 arguments 1.32 + 1.33 + The value of the arguments property is normally null if there is no 1.34 + outstanding invocation of the function in progress (that is, the function has been called 1.35 + but has not yet returned). When a non-internal Function object (15.3.2.1) is invoked, its 1.36 + arguments property is "dynamically bound" to a newly created object that contains the 1.37 + arguments on which it was invoked (see 10.1.6 and 10.1.8). Note that the use of this 1.38 + property is discouraged; it is provided principally for compatibility with existing old code. 1.39 + 1.40 + Author: christine@netscape.com 1.41 + Date: 28 october 1997 1.42 + 1.43 +*/ 1.44 + 1.45 +var SECTION = "15.3.5-1"; 1.46 +var VERSION = "ECMA_1"; 1.47 +startTest(); 1.48 +var TITLE = "Properties of Function Instances"; 1.49 + 1.50 +writeHeaderToLog( SECTION + " "+TITLE); 1.51 + 1.52 +var args = ""; 1.53 + 1.54 +for ( var i = 0; i < 2000; i++ ) { 1.55 + args += "arg"+i; 1.56 + if ( i != 1999 ) { 1.57 + args += ","; 1.58 + } 1.59 +} 1.60 + 1.61 +var s = ""; 1.62 + 1.63 +for ( var i = 0; i < 2000; i++ ) { 1.64 + s += ".0005"; 1.65 + if ( i != 1999 ) { 1.66 + s += ","; 1.67 + } 1.68 +} 1.69 + 1.70 +MyFunc = new Function( args, "var r=0; for (var i = 0; i < MyFunc.length; i++ ) { if ( eval('arg'+i) == void 0) break; else r += eval('arg'+i); }; return r"); 1.71 +MyObject = new Function( args, "for (var i = 0; i < MyFunc.length; i++ ) { if ( eval('arg'+i) == void 0) break; eval('this.arg'+i +'=arg'+i); };"); 1.72 + 1.73 + 1.74 +new TestCase( SECTION, "MyFunc.length", 2000, MyFunc.length ); 1.75 +new TestCase( SECTION, "var MY_OB = eval('MyFunc(s)')", 1, eval("var MY_OB = MyFunc("+s+"); MY_OB") ); 1.76 +new TestCase( SECTION, "MyFunc.prototype.toString()", "[object Object]", MyFunc.prototype.toString() ); 1.77 +new TestCase( SECTION, "typeof MyFunc.prototype", "object", typeof MyFunc.prototype ); 1.78 + 1.79 + 1.80 +new TestCase( SECTION, "MyObject.length", 2000, MyObject.length ); 1.81 + 1.82 +new TestCase( SECTION, "FUN1 = new Function( 'a','b','c', 'return FUN1.length' ); FUN1.length", 3, eval("FUN1 = new Function( 'a','b','c', 'return FUN1.length' ); FUN1.length") ); 1.83 +new TestCase( SECTION, "FUN1 = new Function( 'a','b','c', 'return FUN1.length' ); FUN1()", 3, eval("FUN1 = new Function( 'a','b','c', 'return FUN1.length' ); FUN1()") ); 1.84 +new TestCase( SECTION, "FUN1 = new Function( 'a','b','c', 'return FUN1.length' ); FUN1(1,2,3,4,5)", 3, eval("FUN1 = new Function( 'a','b','c', 'return FUN1.length' ); FUN1(1,2,3,4,5)") ); 1.85 + 1.86 +test();
