Question

Via ajax-based script i get object:

for example:

item.TYP_PCON_START

which value is, for example 201212…
When i try to slice him, i get oject error…

How could i slice this object so, that for example i get 2012, or better set two last numbers on furst place and add dot, like:

12.2012

How could i do this? (i append this text as value of select list)

Answer 1

You need to slice the string property, not the object itself:

item.TYP_PCON_START.slice(-2) + '.' + item.TYP_PCON_START.slice(0, 4);
> '12.2012'

edit: In the case that your property is a number, you must convert it to a string before attempting to slice it:

var propertyAsString = item.TYP_PCON_START.toString();
propertyAsString.slice(-2) + '.' + propertyAsString.slice(0, 4);
> '12.2012'
