Hi all:
I´m new to JQuery, so maybe i´m doing something badly.
I have a previously defined javascript tree, i´m rewriting the code
to use ajax.
This tree has a function
beforedelete: function(node)
If this function returns false, no node will be deleted in user
interface. If sends true, the node is deleted.
I need to use $.get to decide if the tree node is deletable or not,
so i write this code:
beforedelete: function(NODE) // before delete - should return true |
false
{
isOK = false;
$.get("/isdeletable", { 'node': [ NODE ]} ,
function (data)
{
if (data == 1)
isOK = true;
else
isOK = false;
}
);
return isOK;
}
isOK is a global variable.
I can get the result (for the moment simple 0 or 1) from the server
side script. It works correctly.
The problem is that beforedelete finished his work before i get the
data from the server (i discover it putting an alert before the
return).
So it seems that this method is not valid, but i need to analyze
the answer and that beforedelete sends the correct value.
What is the way to do it?
Thank you in advance.
