I have been testing this bug both on IE7 and Firefox 3
short description:
when creating an array and intilizing elements with not consecutive
index
the $each() function will not iterate over the array as expected, for
me its returned
some undefiend.
while in firefox its work as expected.
currently to solve the problem I use the Hash.each to get it work on
both browsers
more to note that firefox, work both with Hash.each and Array.each
with the same result
--------------------------------------
here is a small unit test i created
------
function TEST_0001(){
/*
Test Description
Create an Array
Assign element with "random" indexs
Iterate over the Elements using $each
*/
myTest = Array();
myTest[1] = 'I ';
myTest[4] = 'In ';
myTest[7] = 'Order ';
myTest[5] = 'The Right ';
myTest[2] = 'Am ';
result = "";
$each(myTest,function(t,i){
//alert(i + ' : ' + t);
result += t ;
}.bind(result));
if (result == 'I Am In The Right Order '){
return true;
} else {
return false;
}
}
function TEST_0002(){
/*
Test Description
Create an Array
Assign element with "random" indexs
Iterate over the Elements using Array.each
*/
myTest = Array();
myTest[1] = 'I ';
myTest[4] = 'In ';
myTest[7] = 'Order ';
myTest[5] = 'The Right ';
myTest[2] = 'Am ';
result = "";
Array.each(myTest,function(t,i){
//alert(i + ' : ' + t);
result += t ;
}.bind(result));
if (result == 'I Am In The Right Order '){
return true;
} else {
return false;
}
}
function TEST_0003(){
/*
Test Description
Create an Array
Assign element with "random" indexs
Iterate over the Elements using Hash.each
both firefox and IE will pass this test
the only diffrent is that firefox will sort the element by index order
while IE will iterate over the element in the same order they
"assigned"

myTest = Array();
myTest[1] = 'I ';
myTest[4] = 'In ';
myTest[7] = 'Order ';
myTest[5] = 'The Right ';

//alert(i + ' : ' + t);

alert(result);
if (result == 'I Am In The Right Order ' || result == 'I In Order The
Right Am '){ //the order is less importent
return true;
} else {
return false;
}
}
alert(TEST_0001.run()?'passed':'failed'); //$each
alert(TEST_0002.run()?'passed':'failed'); //Array.each
