View Full Version : Is there any way to 'getAttribute' by string of a field component?

4 Apr 2012, 9:09 AM

I wanna set properties of a textfield via loop the store, code is like this(just for example):

Like I hava a textfield and store:

var field = Ext.create('Ext.field.textfield');
var store = Ext.create('Ext.store.Store'){
field :[
name: 'x',
value: 99
name: 'y',
value: 100
name: 'width',
value: 220

Now I loop the store and set the specified property of the textfield:

var index;
for(var i = 0; i < store.length; i++)
index = store[i].name;
field.index = store[i].value; //It's wrong even I want to use it in this way

I can set properties via 'applyIf' or 'setWidth' methods, but now I really need to do it like this.
Is there a 'getAttribute' method for component just like that for element so that I can change the code to "field.getAttribute(index) = store[i].value" ?
Or other solutions?

Thanks in advance!
