Regular expression problem
Dear friends,
In my script i have some sections which test the content of an edit field before it is processed further.
Things like the following work perfectly:
var re_Def = /#[A-Za-z][A-Za-z0-9_]+/; // valid variable name ?
items = ["#correct", "notcorrect", "#This_is4", "#thisIs", "@something", "#ALLOK", "", ];
// search 0 -1 -1!! -1!! -1 -1!! -1 <--- incorrect method
// test true false true true false true false <--- correct method
for (var j = 0; j < items.length; j++) {
var item = items;
alert ("'" + item + "' ==> " + item.search(re_Def) + "\n" + re_Def.test(item));
}
var re_Def = /(\[ROW +\d+\]|\[COL +\d+\]|\[CELL +\d+, +\d+\]|Left *\(\d*\)|Right *\(\d*\)|Above *\(\d*\)|Below *\(\d*\))/;
items = ["[ROW 17]", "[Row n]", "[ROW n]", "[CELL 3, 9]", "[CELL 3 9]", "Abbove()", "Right(3)"];
// result true false false true false false true
for (var j = 0; j < items.length; j++) {
alert ("'" + items+ "' ==> " + re_Def.test(items ));
}
But the following always return false, independly of the content of the string item:
var re_Def = /{[EFJ]\d*}|{I}/; // valid format def?
var item = "{E27}";
var result = re_Def.test(item);
alert (result); // false !!
RegEx Buddy tells me, that
- the REGEX is correct
- the result should be true, not false
- The verbose defintion of the RegEx is:
Match either the regular expression below (attempting the next alternative only if this one fails) «{[EFJ]\d*}»
Match the character “{” literally «{»
Match a single character present in the list “EFJ” «[EFJ]»
Match a single digit 0..9 «\d*»
Between zero and unlimited times, as many times as possible, giving back as needed (greedy) «*»
Match the character “}” literally «}»
Or match regular expression number 2 below (the entire match attempt fails if this one fails to match) «{I}»
Match the characters “{I}” literally «{I}»
Unrecognised typo? Faulty method test?
Results are wrong as soon as i use character list [...] - but look at the first code block: there are also character lists which are handled correctly.
