using JSONP inside Webix Jet

Webix JS
#1

Hi all
i’m try to do some test with webix jet;
first i would try to replace data,js retrive data, calling a my web service …
i insert in data.js this web service call ( i know that i should do that in records.js but for testing …)

init(view){
webix.jsonp("http://192.168.1.1:10072/jsondemo/wcont.pgm", {}, function(data){
         view.parse(data);

but i receive error :
Uncaught SyntaxError: Unexpected token : wcont.pgmjsonp=webix.jsonp.webix_jsonp_1514502758519:2

if i click in wconto.pgm … i see the Json result of my web service

"{
    "success": true,
    "errmsg": "",
    "items": [
        {
            "id": 0,
            "name": "CUST",
            "country": "",
            "zip": 0,
            "city": "",
            "street": ""
        }, ........
"

and the error seems to be at first line at the “true” values …
can some one help me to understand where am i wrong ?

Keep in mind that i had to replace webix.ajax() with webix.jsonp (i received error "… No ‘Access-Control-Allow-Origin’ header is present …) and that with webix.ajax() in other App, the web service and the relative load table works fine

Hello,

Please, note that JSONP requires that your backend script should output not just plain JSON, but the same JSON “padded” into a Javascript function call.

Since webix.jsonp creates this function automatically, you can get its name on backend as $_GET["JSONP"] and prepend it to your JSON in the way described by the link.
