hi ...

the best way would be to put the optionvalues and texts into an js-array ... sort this now ... and after this is sorted ... populate your menulist with the sorted values

kind regards

Hi gits,

i have the xml like

<LETTER file="ATM_Letter.doc" text="ATM Letter"/>
<LETTER file="Collateral_Correction_Letter_and_CCS.doc" text="Collateral Correction Letter and CCS"/>
.....................
..............

I am populating the xml values in menu options like following.
var menuOption = new Option(text , file, false, false);

How can I convert this Option to Array?

Heya, Bhavanirayala.

Please use CODE tags when posting source code:

[CODE=xml]
XML code goes here.
[/CODE]

This is not the first time you've been asked.

hi ...

you don't have to convert this ... or whatever. simply put them into a list that is indexed with the key you want to sort:

var list = {};
var sort_list = [];
 
// everytime you have retrieved a new option
// you do:
list[text] = menuOption;
 
// where menuOption is the ref to the new Option() you already have
// AND !!!
sort_list.push(text);
 

now you may simply sort the sort_list with the array sort() method.
after that ... you loop through the sorted list, and get the corresponding option from our 'option'-list:

for (var i = 0; i < sort_list.lenght; i++) {
    var item = sort_list[i];
    var option_to_add = list[item];
    // add the option here to your menulist :)
}
 

kind regards
