Alpha 2 of Jack Slocum's Ext 1.0 UI library for jQuery Now Available

The alpha 2 release of Jack Slocum's Ext 1.0 for jQuery is available for download. This is an important release as it officially decouples YUI from Ext and makes Ext 1.0 a standalone project. Users will now have a choice between leveraging the fast, compact and lightweight jQuery Ajax library or the well-documented and robust YUI library.

Ext 1.0 is out(alpha)

Ext 1.0 alpha is out and now I have a lot of work to do.Here is my priority list

1)Update the samples at my website to use the new grid.

2)Update the codeplex project code to use the new grid.

3)Make samples for the TreePanel and put then at my website

4) Implement the treepanel in yui-ext controls and see if there is any other new control I can implement.

The update on my site is already in progress...but there are very complex samples and very few documentation.But as soon as I update my site, updating the control js code will be a breeze.

Samples

The Barchart sample in my website is now working in IE and Firefox.

I don't know if it supports other browsers. The lineChart sample has to be perfected to Firefox...

The secret to get the chart working in Firefox is the content-type to

image/svg+xml. In .net you can set this with this code in Page_load method.

(Request.Browser.Browser != "IE")

{

Response.ContentType = "image/svg+xml";

}

How do I persist a TreePanel?

Ext its not out yet but here is the code:

YAHOO.ext.tree.TreePanel.prototype.toJsonString=function(){
var nodes=this.getRootNode().childNodes;
this.arrNodes=[{id:this.getRootNode().id,parent:0}];
  for(var i=0;i< nodes.length;i++){
       this.arrNodes.push({id:nodes[i].id,parent:this.getRootNode().id});
       this.processChildren(nodes[i]);
  }
  return YAHOO.ext.util.JSON.encode(this.arrNodes);
}
/*
    Recursive function 
    sweeps the tree in all levels
*/
YAHOO.ext.tree.TreePanel.prototype.processChildren=function(node){
   child=node.childNodes;
   for(var i=0;i<child.length;i++){
       this.arrNodes.push({id:child[i].id,parent:node.id});
       this.processChildren(child[i]);
   }
}

It returns a jsonString with an array of objects with the tree nodes and its parents reflecting the changed tree. When Ext comes out I will build a complete sample persisting that output to a database.
