ExtJS - Get array on DOM nodes in Grid, highlight()?

Here's what I'm trying to accomplish. I have a grid with entries that a user can "batch update", that is a user can select a single or multiple entries from the grid, select values from a form above the grid that they want to apply to all entries, and then submit.

What I'd like to accomplish is a highlight() done on all the changes rows. The problem I'm having is I don't know how to run a highlight() on all of the changes values at once, so I've been doing it individually. I might just be running through the loop wrong. Here's what I'm doing to update the values.

// for every property we have in our batchUpdateValues
for (var propertyName in batchUpdateValues) {

    // change the selected banners attributes to match
    for (var i = 0 ; i < bannersToUpdate.length ; i++)
    {
        // if they've selected "Name", we only want to append, not replace"
        var oldName = bannersToUpdate[i].get('bannerName');
        if (propertyName == 'bannerName') {
            bannersToUpdate[i].set(propertyName, oldName +  ' ' + batchUpdateValues['bannerName']);
        } else {
            banners开发者_运维问答ToUpdate[i].set(propertyName, batchUpdateValues[propertyName]);
        }

        var changedRowId = this.getStore().indexOf(updatedBanners[i]);
        var changedRow = this.getView().getRow(changedRowId);
        Ext.get(changedRow).highlight();                   

    }                               
}

What's happening now is if the user selects 4 "attributes" to update form the form the highlight gets run 4 times, so I'd need to put that code outside the loop. How would I grab all of the DOM attributes for each row and then run a highlight on them()?

My first suggestion is to make sure you understand the SelectionModel. It's described in the documentation. I'd link you but I'm not sure which version you're using. Actually, what version of Ext JS are you using? The answer to this question might be different in 3.x vs. 4.x.

I'd be happy to answer in more detail but I'll need you to clarify with an example. Could you build a small table with some dummy data and then explain when you're talking about rows/columns in the model?
