Question
splicing non id arrays
ey everyone I need help with the following:
I have an array ...
array[506484] = blah
array[506688] = blah
array[506445] = blah
etc
those numbers are NOT array ids but identifiers... I need to remove some of them but when I use splice I think what's happenning is that the splice function is interpeting the nubmers as array IDS rather then textual ids... ie: for ( index in array )
any ideas? thanks guys

Hello Gwyn, can you have a look at my calculation here: http:Q_21480616.html
And for here, no splice needed to remove an associative indexed element.
Simply delete it:
<script>
blah = "BLa Blah";
array = new Array();
array[506484] = blah
array[506688] = blah
array[506445] = blah
alert(array.length);
array["506484x"] = blah
array["506688x"] = blah
array["506445x"] = blah
alert(array.length);
delete array["506688x"];
alert(array.length);
array.length = 0;
for(i in array){
alert(i+": "+array[i]);
}
</script>
thanks Zvonko... I emulated it by doing a delete on the element i'm moving, then just rebuilding the array, and re-inserting the element at the row necesarry. Works fine. I was guessing the splice and slice would not work, but figured I'd ask here first just to make sure.
And sorry for the question here. I thought it was relevant to the question at hand (since VFM-Tech was thinking his were being evaluated as text indexes). Lesson learned ;)

They ARE numeric indexes and not hash string associative indexes.
To make them associative indexes you have to add an alpha character to the key.
