How do I delete (and insert) a Row with own Index

hi experts,

i am trying to delete (and insert) rows in my grid.
the hints found in this forum may work wonderful, if you use
indexing by default, but i use a database-field as index and
so method like slice or splice do not work as they are supposed..

i define my grid as follows:

GridData = {
"dbIdx1":["a","b,"c"],
"dbIdx2":["a","b,"c"],
"dbIdx3":["a","b,"c"]
}

any help is appreciated, thanks a lot in advance,
yves

since associative arrays do not support some methods a normal array does (e.g. length, splice and so on) this would be quite complicated hack...
so i switched to a normal griddata-array and everything´s fine now...
... or does anybody has a quick solution?

thanks anyway,
yves

This is so simple.

There is an operator in Javascript called delete. All you need to do in order to delete a row from an associative array is to do something like this :

GridData = {
"dbIdx1":["a","b,"c"],
"dbIdx2":["a","b,"c"],
"dbIdx3":["a","b,"c"]
}

delete GridData[dbIdx2]; //This will remove the second row

My own example is:

<script language="JavaScript" type="text/JavaScript">
    var d = new Array();
    d['a'] = 'First Element';
    d['b'] = "BBb";
    d["c"] = "CCC";
    d['d'] = "DDD";
    document.write ("<br />d['a']="+d['a']+"<br />");

</script>
<br><input type="button" onClick="delete d['a']" value="Delete It"><!-- And the first element WAS -->
<input type="button" onClick="alert(d['a'])" value="Show It"><!-- The first element IS -->

Oops, I forgot the quotation marks

GridData = {
"dbIdx1":["a","b,"c"],
"dbIdx2":["a","b,"c"],
"dbIdx3":["a","b,"c"]
}

delete GridData['dbIdx2']; //This will remove the second row
