jQuery equivalent

[evant]

Another way to do it without filter:

Ext.select('a').each(function(el){
    if(el.dom.hostName != location.hostName){
        el.addClass('external');
    }
});

In its current form where it filters using a string selector as the parameter, or will it be upgraded to accept a selection function in addition?

What about this jQuery-Code?

$('td:contains(Henry)').nextAll().andSelf().addClass('highlight'); 

Highlight all of the cells following the one containing Henry (include the one that contains Henry)

Are you porting something to Ext Core?

Something like:

var el = Ext.select('td:contains(Henry)').item(0);
while(el){
    el = el.addClass('highlight').next();
}

I'm thinking about the possiblity of an override statement which adds come of these obscure capabilities. Pretty easy to add them. CompositeElement just encapsulates a set of DOM elements.

No, only compare the libraries. Not sure which one I should use. (Sorry for my bad english)

Like this:

Ext.override(Ext.CompositeElementLite, {

//  need this until next release - pulled in from full Ext
    fill : function(els){
        var me = this;

//      Keep reference to last version of self before refill
        me.prevObject = new me.constructor(me.elements);

        me.elements = [];
        me.add(els);
        return me;
    },

    nextAll: function() {
        var els = this.elements, i, l = els.length, n, r = [], ri = -1;
        for (i = 0; i < l; i++) {
            for (n = els[i].nextSibling; n; n = n.nextSibling) {
                r[++ri] = n;
            }
        }
        this.fill(r);
        return this;
    },

    andSelf: function() {
        if (this.prevObject) {
            this.add(this.prevObject.elements); // add takes an Array. Should it take another Composite???
        }
        return this;
    }
});

Then you would use

Ext.select('td:contains(Altria)').nextAll().andSelf().addClass('x-grid3-dirty-cell');

(As tested on the array-grid example in ExtJs examples as you can tell by the data)

Instructive code, thx

[evant]

A filter method that accepts a function would be good. I'm playing around with some code now:

Ext.onReady(function(){
    for(var i = 0; i < 10; ++i){
        Ext.getBody().createChild({
            tag: 'div',
            cls: i % 2 == 0 ? 'foo' : 'bar'
        });
    }
    console.log(Ext.select('div').filter('.foo').getCount());
    console.log(Ext.select('div').filter(function(el){
        return el.is('.foo');
    }).getCount());
});

Obvoiusly both return the same results.
