Static Variables from Static Class not updated

Question

User659967990 posted

Hello,

I have quartz .net n my MVC application to execute job at 1 minute interval, my job sets value to my static variables present in static global class.

I am then passing static variable values to my html element at javascript setinterval() but in my case values in static varaible are not getting updated.

But when i place breakpoint to quartz job I can see static variable value is being set, Please help me where I am doing wrong

setInterval(function () {
        var x =  @AppName.Globals.Variable1;
        var y = @AppName.Globals.Variable2;
        var z = @AppName.Globals.Variable3;
        $("#Knob1").val(y).trigger('change');
        $("#Knob2").val(z).trigger('change');
        $("#Knob3").val(x).trigger('change');
    },5000);



//My Quartz Job at every 1 Minute
public void Execute(IJobExecutionContext context)
        {
            try
            {
                Random rnd = new Random();
                Globals.Variable1 = rnd.Next(1, 100);;
                Globals.Variable2 = rnd.Next(1, 200);;
                Globals.Variable3 = rnd.Next(1, 300);;
            }
            catch (Exception ex) { string errormsg = ex.ToString(); }
        }


//My Global Static Class
using System;
using System.Collections.Generic;
using System.Linq;
using System.Web;

namespace AppName
{
    public static class Globals
    {
        public static double Variable1 { get; set; }
        public static double Variable2 { get; set; }
        public static double Variable3 { get; set; }
    }
}

The c# static values are only accessed when the view is rendered. The JavaScript variables in are in the browsers JavaScript instance. Your setInverval will need to make an Ajax call to get the current values.

Hi ParthDesai,

For example,you could refer to this demo:

setInterval(function(){ alert("Hello"); }, 3000);

It will wait 3 seconds and alert "Hello" at the first time,and then an new alert box will appear in 3 seconds.

I am then passing static variable values to my html element at javascript setinterval() but in my case values in static varaible are not getting updated.

Actually,your case values will get updated after 5 seconds at the first time,and get updated in 5 seconds ...rather then 'are not getting updated.'

Best Regards.
