problem with associative Array

[vspriya]

Hi,

I have an associative array like
x = {"Some Tag 0":{vals:[{sel:0, val:'SomeTagValue0'}, {sel:0, val:'SomeTagValue1'},{sel:1, val:'SomeTagValue2'}], edit:0},"Some Tag 1":{vals:[{sel:0, val:'SomeTagValue0'}, {sel:0, val:'SomeTagValue0'}], edit:1}};

y = {"Selected Tag 0":{vals:[{sel:0, val:'SomeTagValue0'}, {sel:0, val:'SomeTagValue0'},{sel:1, val:'SomeTagValue1'}], edit:0},"Selcted Tag 1":{vals:[{sel:0, val:'SomeTagValue0'}, {sel:0, val:'SomeTagValue1'}], edit:1}};

I just want to remove "Some Tag 1" from the array x and add it to y in the first position. Can somebody help me?

x and y aren't arrays. They're objects.

You can't add a new property to the beginning of an object in JS. You would need to make a new object in order put a new node (key/value pair) first.

Does the order really matter?

Hi, I need to consider the order also. Can you please tell me how to create new object?

If order is important then put the information into a regular numbered array. Associative arrays and objects DO NOT support any form of ordering whatsoever.

thank you Stephen..But is there any way to append a child in first position?

[felgall]

insertBefore()

[vspriya]

Hi insertBefore is working fine..But cant we use nextsibling? its not working for me in firefox.

Are you sure that nextSibling is referencing the right node. Different browsers treat whitespace differently - whitespace counts as a node in some browsers and not others.
