Custom JavaScript examples

Hi Buuudzik,

Here is a sample for changing color with css based on setpoint and actual value difference.

Give the first setpoint these additional classes 'Setp Setp_1', the 2nd 'Setp Setp_2', the 3th 'Setp Setp_3' etc
Give the first actual these additional classes 'Temp Temp_1', the 2nd 'Temp Temp_2', the 3th 'Temp Temp_3' etc  

So all setpoints will have 2 additional classes (Setp and Setp_nr) and all actuals will have 2 additional classes (Temp and Temp_nr)

Put this code in your custom JavaScript:

Code:

$(function(){
 
 // Set color values
 var defaultcolor = $('.Temp').css("color")
 var highcolor = 'rgb(0, 255, 0)'
 var lowcolor = 'rgb(128, 128, 255)'
 
 // Function to change colors on values
 function CheckSetpointandValue(){
   
   // Set conditions for Setp_1 and Temp_1
   if  ( $(".Temp_1")[0].innerHTML ==  $(".Setp_1")[0].innerHTML){
       $(".Temp_1").css("color", defaultcolor);
   } else if ( $(".Temp_1")[0].innerHTML > $(".Setp_1")[0].innerHTML){
       $(".Temp_1").css("color", highcolor);
   } else if ( $(".Temp_1")[0].innerHTML < $(".Setp_1")[0].innerHTML){
       $(".Temp_1").css("color", lowcolor);
   }
   
   // Set conditions for Setp_2 and Temp_2
   if  ( $(".Temp_2")[0].innerHTML ==  $(".Setp_2")[0].innerHTML){
       $(".Temp_2").css("color", defaultcolor);
   } else if ( $(".Temp_2")[0].innerHTML > $(".Setp_2")[0].innerHTML){
       $(".Temp_2").css("color", highcolor);
   } else if ( $(".Temp_2")[0].innerHTML < $(".Setp_2")[0].innerHTML){
       $(".Temp_2").css("color", lowcolor);
   }
   
   // Set conditions for Setp_3 and Temp_3
   if  ( $(".Temp_3")[0].innerHTML ==  $(".Setp_3")[0].innerHTML){
       $(".Temp_3").css("color", defaultcolor);
   } else if ( $(".Temp_3")[0].innerHTML > $(".Setp_3")[0].innerHTML){
       $(".Temp_3").css("color", highcolor);
   } else if ( $(".Temp_3")[0].innerHTML < $(".Setp_3")[0].innerHTML){
       $(".Temp_3").css("color", lowcolor);
   }
   
 }  
 
 // Check for changes on value of item with Temp
 $('.Temp').bind("DOMSubtreeModified",function(){
   CheckSetpointandValue();
 });
 
 // Check for changes on value of item with Setp
 $('.Setp').bind("DOMSubtreeModified",function(){
   CheckSetpointandValue();
 });
 
 // Initial execution
 CheckSetpointandValue();
 
});

All items with additional class 'Setp' and 'Temp' are monitored on changes and wil execute the function. Based on values the css of the correct item (Temp_nr) will be changed

If you have more then 3 items then you need to add them inside the function CheckSetpointandValue().
