If + positionis undefined or not supplied, 0 is assumed, so + as to search all of the string. + + When the indexOf method is called with two arguments, + searchString and pos, the following steps are taken: + + 1. Call ToString, giving it the this value as its + argument. + 2. Call ToString(searchString). + 3. Call ToInteger(position). (If position is undefined + or not supplied, this step produces the value 0). + 4. Compute the number of characters in Result(1). + 5. Compute min(max(Result(3), 0), Result(4)). + 6. Compute the number of characters in the string that + is Result(2). + 7. Compute the smallest possible integer k not smaller + than Result(5) such that k+Result(6) is not greater + than Result(4), and for all nonnegative integers j + less than Result(6), the character at position k+j + of Result(1) is the same as the character at position + j of Result(2); but if there is no such integer k, + then compute the value -1. + 8. Return Result(7). + + Note that the indexOf 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. + + Author: christine@netscape.com + Date: 2 october 1997 +*/ +var SECTION = "15.5.4.6-1"; +var VERSION = "ECMA_1"; +startTest(); +var TITLE = "String.protoype.indexOf"; + +var TEST_STRING = new String( " !\"#$%&'()*+,-./0123456789:;<=>?@ABCDEFGHIJKLMNOPQRSTUVWXYZ[\\]^_`abcdefghijklmnopqrstuvwxyz{|}~" ); + +writeHeaderToLog( SECTION + " "+ TITLE); + +var j = 0; + +for ( k = 0, i = 0x0020; i < 0x007e; i++, j++, k++ ) { + new TestCase( SECTION, + "String.indexOf(" +String.fromCharCode(i)+ ", 0)", + k, + TEST_STRING.indexOf( String.fromCharCode(i), 0 ) ); +} + +for ( k = 0, i = 0x0020; i < 0x007e; i++, j++, k++ ) { + new TestCase( SECTION, + "String.indexOf("+String.fromCharCode(i)+ ", "+ k +")", + k, + TEST_STRING.indexOf( String.fromCharCode(i), k ) ); +} + +for ( k = 0, i = 0x0020; i < 0x007e; i++, j++, k++ ) { + new TestCase( SECTION, + "String.indexOf("+String.fromCharCode(i)+ ", "+k+1+")", + -1, + TEST_STRING.indexOf( String.fromCharCode(i), k+1 ) ); +} + +for ( k = 0, i = 0x0020; i < 0x007d; i++, j++, k++ ) { + new TestCase( SECTION, + "String.indexOf("+(String.fromCharCode(i) + + String.fromCharCode(i+1)+ + String.fromCharCode(i+2)) +", "+0+")", + k, + TEST_STRING.indexOf( (String.fromCharCode(i)+ + String.fromCharCode(i+1)+ + String.fromCharCode(i+2)), + 0 ) ); +} + +for ( k = 0, i = 0x0020; i < 0x007d; i++, j++, k++ ) { + new TestCase( SECTION, + "String.indexOf("+(String.fromCharCode(i) + + String.fromCharCode(i+1)+ + String.fromCharCode(i+2)) +", "+ k +")", + k, + TEST_STRING.indexOf( (String.fromCharCode(i)+ + String.fromCharCode(i+1)+ + String.fromCharCode(i+2)), + k ) ); +} +for ( k = 0, i = 0x0020; i < 0x007d; i++, j++, k++ ) { + new TestCase( SECTION, + "String.indexOf("+(String.fromCharCode(i) + + String.fromCharCode(i+1)+ + String.fromCharCode(i+2)) +", "+ k+1 +")", + -1, + TEST_STRING.indexOf( (String.fromCharCode(i)+ + String.fromCharCode(i+1)+ + String.fromCharCode(i+2)), + k+1 ) ); +} + +new TestCase( SECTION, "String.indexOf(" +TEST_STRING + ", 0 )", 0, TEST_STRING.indexOf( TEST_STRING, 0 ) ); + +new TestCase( SECTION, "String.indexOf(" +TEST_STRING + ", 1 )", -1, TEST_STRING.indexOf( TEST_STRING, 1 )); + +print( "TEST_STRING = new String(\" !\"#$%&'()*+,-./0123456789:;<=>?@ABCDEFGHIJKLMNOPQRSTUVWXYZ[\\]^_`abcdefghijklmnopqrstuvwxyz{|}~\")" ); + + +test(); |
