Template with icon: possible to change image url dynamically?

[baden32]

The json received with data (not develepped on my side) contains field "type" with a numeric value (1, 3,4, etc.).
This info represent a category and I would like to use template iconLeft in order add an icon according to this value.

In my Easycomplete options, I set this:

template: {
type: "iconLeft",
fields: {
iconSrc: "type"
}
},

As type is only containg a numeric value, no image can be displayed.

So is there a way to dynamically change the received value (in. 2) into a valid image url (ie. /files/images/2.png) ?

Thanks a lot for your help.
