Web Server S7-1200

Hi,

I want to create a web server with auto refresh variables in background. If i have only 1 variable, i can do it. But if i have more than 1 variable, i can not do.

My code is in attached. 

Some help?

The problem isn't refreshing. 

If i put only 1 var in IOCounter.htm, the output in webserver is correct.

If i put more than 1 var in IOCounter.htm, always when i call some var in main, the output is all var that are inside IOCounter.htm.

if you to not parse the result into JSON you get the plain html text back as result.... 

var res = $.parseJSON(result);

$("#var1").text(res.var1) 

In_HMI.html
{
"LV_Corrente":":="HMI".HMI."Paratoia 1"."Livello Corrente":",
"Q_Corrente":":="HMI".HMI."Paratoia 1"."Quota Corrente":",
"Presenza_All":":="HMI".HMI."Paratoia 1"."Grafica Allarme Ostacolo Rilevato":",
"Fondo_Max":":="HMI".HMI."Paratoia 1"."Fondo Scala Superiore Sensore Livello":",
"Fondo_Min":":="HMI".HMI."Paratoia 1"."Fondo Scala Inferiore Sensore Livello":",

}

index.html
<script>
$(document).ready(function(){
$("button").click(function(){
var number1;
alert(number1);
document.getElementById("demo").innerHTML = number1;
$.getJSON("In_HMI.html", function(result){
var res = parseJSON(result);
$('#LV_Corrente').text(res.LV_Corrente);
number1 = res.LV_Corrente;
});
});
});
</script>

 Some ideas?

Hi,

seems to me as the last colon in the json file is one colon to much.... ;-)
Just open the web developer tools in the used browser and have a look into the console which error is mentioned their

sorry, i missed the "$." in front of json parse

it has to be: 

 var res = $.parseJSON(result);

$("#var1").text(res.var1)

 as alternativ you can also choose native java script:

JSON.parse()
