DevGuru JavaScript METHOD: RegExp::exec



			METHOD: RegExp::exec object.exec([str]) object([str]) This method executes a search for a match in a specified string, returning a result array. (If, however, you simply want to test whether or not there is a match, it is best to use the test method or the String.search method.) For example, the following blocks of code, one for the Internet Explorer browser and the other for Netscape, each execute a search of the string "the fisherman" for a match with the regular expression 'rexp'. If one is found (and in the case of the example it is), then an appropriate message is printed. Code: rexp = /[aeiou]/g myString = "the fisherman" if(rexp.exec(myString)) match = rexp.exec(myString) document.write("Successfully matched " + match) Code: rexp = /[aeiou]/g myString = "the fisherman" if(rexp(myString)) match = RegExp.lastMatch document.write("Successfully matched " + match) Output: Successfully matched e NOTE: The Netscape browser can call the exec method both directly (object.exec([str])) or indirectly (object([str])), whereas Microsoft Internet Explorer can only call it directly. If no string is declared then the value of RegExp.input is used. If the search fails, the exec method returns null.
