View Full Version : TreeEditor Validation

30 May 2007, 7:18 AM
:s does anyone know where i can find information about adding vtype validation to a TreeEditor...

I searched the forum, google and the api docs but couldn't find out if /or how to set it up...
...i also could find information about the Ext.Tree.TreeEditor...?

I'm working from the dependency tree example, and i want to have a leaf node only accept digits/numbers into it's text field.

i know that the regex for numbers-only looks something like this:


Many thanks in advance,

ok i found the treeeditor js file it was listed as the subclass of editor.js

sorry for my ignorance.


I also managed to prevent the user from submitting a non-number by attaching a function to the 'beforecomplete' event.

var myTreeEditor = new xt.TreeEditor(ctree, {
blankText:'A valid number is required',

myTreeEditor.on('beforecomplete', function(node, value, startValue){

if ((value.match(/[0-9]+/)) || (value=='')){
return true;
return false;

this works fine except it doesn't tell the user anything informative if they've typed in a character or a space etc...

how can i make the jagged red-underline appear and a quicktip with some useful info.

Many thanks in advance.

sorry the above doesn't quite work...

the regex is wrong it matches numbers anywhere in the string, so there could be other characters there and it will return true. :s
