Hi Marcos N.
I think the problem is in the code. From the image you posted, I see that you have an additional "+" sign before "_blank".
cordova.InAppBrowser.open(valor, + '_blank', 'location=yes');
can you try removing that additional "+" sign and try again?
No Problem Marcos N.!
You can see here how to configure it https://software.intel.com/en-us/xdk/docs/using-the-editor-in-the-develop-tab (Section "Configure JSHint")
