If there is no character at that + string, the result is the empty string. The result is + a string value, not a String object. + + When the charAt method is called with one argument, + pos, the following steps are taken: + 1. Call ToString, with this value as its argument + 2. Call ToInteger pos + 3. Compute the number of characters in Result(1) + 4. If Result(2) is less than 0 is or not less than + Result(3), return the empty string + 5. Return a string of length 1 containing one character + from result (1), the character at position Result(2). + + Note that the charAt function is intentionally generic; + it does not require that its this value be a String + object. Therefore it can be transferred to other kinds + of objects for use as a method. + + This tests assiging charAt to primitive types.. + + Author: christine@netscape.com + Date: 2 october 1997 +*/ +var SECTION = "15.5.4.4-4"; +var VERSION = "ECMA_2"; +startTest(); +var TITLE = "String.prototype.charAt"; + +writeHeaderToLog( SECTION + " "+ TITLE); + +/* + new TestCase( SECTION, "x = null; x.__proto.charAt = String.prototype.charAt; x.charAt(0)", "n", eval("x=null; x.__proto__.charAt = String.prototype.charAt; x.charAt(0)") ); + new TestCase( SECTION, "x = null; x.__proto.charAt = String.prototype.charAt; x.charAt(1)", "u", eval("x=null; x.__proto__.charAt = String.prototype.charAt; x.charAt(1)") ); + new TestCase( SECTION, "x = null; x.__proto.charAt = String.prototype.charAt; x.charAt(2)", "l", eval("x=null; x.__proto__.charAt = String.prototype.charAt; x.charAt(2)") ); + new TestCase( SECTION, "x = null; x.__proto.charAt = String.prototype.charAt; x.charAt(3)", "l", eval("x=null; x.__proto__.charAt = String.prototype.charAt; x.charAt(3)") ); + + new TestCase( SECTION, "x = undefined; x.__proto.charAt = String.prototype.charAt; x.charAt(0)", "u", eval("x=undefined; x.__proto__.charAt = String.prototype.charAt; x.charAt(0)") ); + new TestCase( SECTION, "x = undefined; x.__proto.charAt = String.prototype.charAt; x.charAt(1)", "n", eval("x=undefined; x.__proto__.charAt = String.prototype.charAt; x.charAt(1)") ); + new TestCase( SECTION, "x = undefined; x.__proto.charAt = String.prototype.charAt; x.charAt(2)", "d", eval("x=undefined; x.__proto__.charAt = String.prototype.charAt; x.charAt(2)") ); + new TestCase( SECTION, "x = undefined; x.__proto.charAt = String.prototype.charAt; x.charAt(3)", "e", eval("x=undefined; x.__proto__.charAt = String.prototype.charAt; x.charAt(3)") ); +*/ +new TestCase( SECTION, "x = false; x.__proto.charAt = String.prototype.charAt; x.charAt(0)", "f", eval("x=false; x.__proto__.charAt = String.prototype.charAt; x.charAt(0)") ); +new TestCase( SECTION, "x = false; x.__proto.charAt = String.prototype.charAt; x.charAt(1)", "a", eval("x=false; x.__proto__.charAt = String.prototype.charAt; x.charAt(1)") ); +new TestCase( SECTION, "x = false; x.__proto.charAt = String.prototype.charAt; x.charAt(2)", "l", eval("x=false; x.__proto__.charAt = String.prototype.charAt; x.charAt(2)") ); +new TestCase( SECTION, "x = false; x.__proto.charAt = String.prototype.charAt; x.charAt(3)", "s", eval("x=false; x.__proto__.charAt = String.prototype.charAt; x.charAt(3)") ); +new TestCase( SECTION, "x = false; x.__proto.charAt = String.prototype.charAt; x.charAt(4)", "e", eval("x=false; x.__proto__.charAt = String.prototype.charAt; x.charAt(4)") ); + +new TestCase( SECTION, "x = true; x.__proto.charAt = String.prototype.charAt; x.charAt(0)", "t", eval("x=true; x.__proto__.charAt = String.prototype.charAt; x.charAt(0)") ); +new TestCase( SECTION, "x = true; x.__proto.charAt = String.prototype.charAt; x.charAt(1)", "r", eval("x=true; x.__proto__.charAt = String.prototype.charAt; x.charAt(1)") ); +new TestCase( SECTION, "x = true; x.__proto.charAt = String.prototype.charAt; x.charAt(2)", "u", eval("x=true; x.__proto__.charAt = String.prototype.charAt; x.charAt(2)") ); +new TestCase( SECTION, "x = true; x.__proto.charAt = String.prototype.charAt; x.charAt(3)", "e", eval("x=true; x.__proto__.charAt = String.prototype.charAt; x.charAt(3)") ); + +new TestCase( SECTION, "x = NaN; x.__proto.charAt = String.prototype.charAt; x.charAt(0)", "N", eval("x=NaN; x.__proto__.charAt = String.prototype.charAt; x.charAt(0)") ); +new TestCase( SECTION, "x = NaN; x.__proto.charAt = String.prototype.charAt; x.charAt(1)", "a", eval("x=NaN; x.__proto__.charAt = String.prototype.charAt; x.charAt(1)") ); +new TestCase( SECTION, "x = NaN; x.__proto.charAt = String.prototype.charAt; x.charAt(2)", "N", eval("x=NaN; x.__proto__.charAt = String.prototype.charAt; x.charAt(2)") ); + +new TestCase( SECTION, "x = 123; x.__proto.charAt = String.prototype.charAt; x.charAt(0)", "1", eval("x=123; x.__proto__.charAt = String.prototype.charAt; x.charAt(0)") ); +new TestCase( SECTION, "x = 123; x.__proto.charAt = String.prototype.charAt; x.charAt(1)", "2", eval("x=123; x.__proto__.charAt = String.prototype.charAt; x.charAt(1)") ); +new TestCase( SECTION, "x = 123; x.__proto.charAt = String.prototype.charAt; x.charAt(2)", "3", eval("x=123; x.__proto__.charAt = String.prototype.charAt; x.charAt(2)") ); + + +test(); |
