New Java API idea: ext4j

[wxz20032003]

u mean a tag ?just like some open-src program?

[mglaser]

By tag I meant attribute eg:

<div id="toolbar" extType="Ext.PagingToolbar" container="gridFoot" dataStore="ds" pageSize="20" displayInfo="true" displayMsg="total {2} results found. Current shows {0} - {1}" emptyMsg="not result to display"></div>

to instantiate the toolbar rather than:

var paging = new Ext.PagingToolbar(gridFoot, ds, {
pageSize: 20,
displayInfo: true,
displayMsg: 'total {2} results found. Current shows {0} - {1}',
emptyMsg: "not result to display"
});

You should definitely be using namespaces on those attributes:

<div id="toolbar" ext:Type="Ext.PagingToolbar" ext:container="gridFoot" ext:dataStore="ds" ext:pageSize="20" ext:displayInfo="true" ext:displayMsg="total {2} results found. Current shows {0} - {1}" ext:emptyMsg="not result to display"></div>

Client side tags are not as useful IMNSHO as server-side tags which may take full Java Objects as attributes, introspect app metadata and create complex markup and script.

For example, I now have an <aspicio:view> tag which creates a DnD enabled Ext.View of a collection of beans. So in my JSP I have

	<aspicio:column>
		<aspicio:fieldset style="margin-left:10px" legend="Subcomponents">
			<aspicio:view
				style="height:300px"
				dropgroup="availableSubcomponents"
				draggroup="availableSubcomponents"
				id="subComponents"
				collection="<%=entity.getSubComponents()%>"
				type="<%=Component.class%>"
				template="<div id='subcomponent_{id}' class='Subcomponent'><img align='top' height='16px' width='16px' src='{entityImageUrl}'>{componentDescription}</div>"/>
		</aspicio:fieldset>
	</aspicio:column>
	<aspicio:column>
		<aspicio:fieldset style="margin-left:10px" legend="Available subcomponents">
			<aspicio:view
				style="height:300px"
				dropgroup="availableSubcomponents"
				draggroup="availableSubcomponents"
				select="multi"
				collection="<%=availableSubcomponents%>"
				type="<%=Component.class%>"
				template="<div id='component_{id}' class='Component'><img align='top' height='16px' width='16px' src='{entityImageUrl}'>{componentDescription}</div>"/>
		</aspicio:fieldset>
	</aspicio:column>

It provides views of the "Component" objects in the two collections, and allows drag/dropping between the two (because they share dragGroup/dropGroup ids).

The {xxx} substitution elements in the Template correspond to properties of the bean class.

Most JSP authors seem to be clueless about Javascript, and this seems like the best way to get a good UI without frightening them!

<div id="toolbar" extType="Ext.PagingToolbar" container="gridFoot" dataStore="ds" pageSize="20" displayInfo="true" displayMsg="total {2} results found. Current shows {0} - {1}" emptyMsg="not result to display"></div>

That's dojo-esque, and I personally don't think it's a pretty good idea. When I'm formulating pages, especially rich ones, a lot of them are just bare pages with just a few empty divs here and there.

The one thing that always bothered me about it was the namespacing of non-xhtml attributes. I mean, if you want to use xhtml, you should be able to do it properly :

<div id="toolbar" ext:extType="Ext.PagingToolbar" ext:container="gridFoot" ext:dataStore="ds" ext:pageSize="20" ext:displayInfo="true" ext:displayMsg="total {2} results found. Current shows {0} - {1}" ext:emptyMsg="not result to display"></div>

I agree completely. I only mentioned namespaced attributes because the OP was suggesting client-side tags.

Hi guys,

Lilya - Jsf Widgets with Ajax Capabilities based on ExtJs and JsGraphics is now available (lilya 1.0-beta-1).

Demo, documentation and downloads at Lilya Home Page

We need your comments !

I hope that this work helps interested.

[IGx89]

Good to hear! However, on IE7 (haven't tried other browsers) your "View Sources" link just grays out everything without doing anything productive.

thanks matthew. Now it's working.
