Let S be the value of ToString(string). + * 2. Let length be the length of S. + * 3. Let lastIndex be the value of the lastIndex property. + * 4. Let i be the value of ToInteger(lastIndex). + * 5. If the global property is false, let i = 0. + * 6. If i < 0 or i > length then set lastIndex to 0 and return null. + * 7. Call [[Match]], giving it the arguments S and i. + * If [[Match]] returned failure, go to step 8; + * otherwise let r be its State result and go to step 10. + * 8. Let i = i+1. + * 9. Go to step 6. + * 10. Let e be r's endIndex value. + * 11. If the global property is true, set lastIndex to e. + * + * etc. + * + * + * So when the global flag is set, |lastIndex| is incremented every time + * there is a match; not from i to i+1, but from i to "endIndex" e: + * + * e = (index of last input character matched so far by the pattern) + 1 + * + * Thus in the example below, the first endIndex e occurs after the + * first match 'a b'. The next match will begin AFTER this, and so + * will NOT be 'b c', but rather 'c d'. Similarly, 'd e' won't be matched. + */ +//----------------------------------------------------------------------------- +var i = 0; +var BUGNUMBER = '(none)'; +var summary = 'Testing regexps with the global flag set'; +var status = ''; +var statusmessages = new Array(); +var pattern = ''; +var patterns = new Array(); +var string = ''; +var strings = new Array(); +var actualmatch = ''; +var actualmatches = new Array(); +var expectedmatch = ''; +var expectedmatches = new Array(); + + +status = inSection(1); +string = 'a b c d e'; +pattern = /\w\s\w/g; +actualmatch = string.match(pattern); +expectedmatch = ['a b','c d']; // see above explanation - +addThis(); + + +status = inSection(2); +string = '12345678'; +pattern = /\d\d\d/g; +actualmatch = string.match(pattern); +expectedmatch = ['123','456']; +addThis(); + + + +//----------------------------------------------------------------------------- +test(); +//----------------------------------------------------------------------------- + + + +function addThis() +{ + statusmessages[i] = status; + patterns[i] = pattern; + strings[i] = string; + actualmatches[i] = actualmatch; + expectedmatches[i] = expectedmatch; + i++; +} + + +function test() +{ + enterFunc ('test'); + printBugNumber(BUGNUMBER); + printStatus (summary); + testRegExp(statusmessages, patterns, strings, actualmatches, expectedmatches); + exitFunc ('test'); +} |
