row expander

[tunaboo]

I am using the nifty row-expander code from one of the demos.

1) Can a row expander have a renderer? In the source code for row-expander I see...

    renderer : function(v, p, record){
        p.cellAttr = 'rowspan="2"';
        return '<div class="x-grid3-row-expander"> </div>';
    }, 

So seems like I should be able to update that? What I want to do is call a JSP page to render my HTML for me, and shove it in the box.


I am trying to do something like this

    var expander = new xg.RowExpander({
        renderer: renderExpander
   })


renderExpander: function(v, p, record){
     var html = "<br />";
     var html += http://server-name.com/doSomeCrap.do;
     return html 

The doSomeCrap.do would call spring, do some java work, call a jsp, which would return some formated HTML.



I realize that row-expander is usually preloaded content, am I going outside of the scope of this, and should just make a new class instead?

Also, wtf does the v, p, and record represent in the row expander? Record I can guess.. v and p not so easy.

v = value
p = last column defined in the column model? <--- this is what i could tell.

Is that how I replace the renderer class? Just declare a new one, and it will use that instead of the normal row expander one? /goes off to research inheritance in JS

yeah

Example:

    function formatBox(_1, _2) {
        if (_1 != _2) {
            return (String.format('<span class="dnsAuditPreChange" style="text-decoration: line-through;">{0}</span>&nbsp;<hr style="height: 1px;" /><span style="font-weight: bold;">{1}</span>', _1, _2));
        }
        else {
            return (String.format('<span class="dnsAuditPreChange">{0}</span>&nbsp;<hr /><span style="color: #000000">{1}</span>', _1, _2));
        }
    }
    function renderHostnames(value, p, record){
    
        return( formatBox(record.data['PRE_HOSTNAME'], record.data['POST_HOSTNAME']));
        
    }

argh not even sure its the renderer I want to mess with, what I really need to do is change the template when I get an expand event.

Humm how to have the template loaded from a jsp instead of hard coded, that is the question..

You're going to have to return an iframe if you want to accomplish this.

or do an ajax call which gets can be hairy because of it being asynchronous

ugh
