Date Differences in PHPRunner

Although I can't get you exactly what you need, you will have to use javascript for this. Type "javascript date" in the forum search and this should get you started.

Thank you, I have searched through the forums as well as web searches. I am fairly familiar with JavaScript. I am focusing on the date diff at the moment.
I added two fields

strtotime_start

strtotime_end
Placed the code below, just to populate the strtotime when start loses focus. I even tried it with change and nothing happens.

I even tried ctrlstrtotime.setValue(Date,(ctrlstart.getValue()));and in the View As $value = strtotime("start").
I can get the checkbox and hidden fields working. It's the .on and setValue I am having the struggles with.
Thanks!

While I don't have an answer to this specific question there are troubleshooting steps you need to take:

1. Make sure there are no Javascript errors thrown
   
2. Make sure your code in 'on' event is execute. You can do that adding function like alert() there.
   
3. Once you figured out that code is in fact is executed you need to troubleshoot it a little further. Set a breakpoint inside 'on' function handler and inspect variable values to see what is going on.

Thank you for the recommendation.

Thanks for the suggestions and links. Although helpful, they appear to me to over complicate things a bit.
I able to the following with fairly simple code. I am sharing the code below in case other newbies to PHPRunner run across similar challenges.

• DATE_DIFF - without the need of addition strtotime translation
  
• Select/Unselect Checkbox
  
• hide/show fields with the simple code pasted below:
  

1. Set up 2 proxy values on the Before Display
   
2. Add code on Javascript onload event
   if (proxy.start='""'){
   
   pageObj.hideField('strtotime_start');
   
   var ctrlstart = Runner.getControl(pageid, 'start');
   
   var ctrlstrt = Runner.getControl(pageid, 'strtotime_start');
   
   var check = Runner.getControl(pageid, 'checkbox');
   
   ctrlstart.on('blur', function() {
   
   // call 'setValue' method to set new value
   
   if(ctrlstart.getValue() != "" && ctrlend.getValue() != ""){
   
   var date1 = new Date(ctrlstart.getValue());
   
   var date2 = new Date(ctrlend.getValue());
   
   var numMonths = (date2.getFullYear() - date1.getFullYear()) 12 + (date2.getMonth() - date1.getMonth());
   
   if(date1.getDate() > date2.getDate())
   
   numMonths--;
   
   alert(numMonths + "");
   
   if(numMonths < 24)
   
   {
   
   check.setValue(true);
   
   pageObj.showField('strtotime_start');
   
   pageObj.showField('strtotime_end');
   
   }
   
   else
   
   {
   
   check.setValue(false);
   
   pageObj.hideField('strtotime_start');
   
   pageObj.hideField('strtotime_end');
   
   }
   
   ctrlstrt.setValue(ctrlstart.getValue()+"");
   
   }
   
   });
   if (proxy.end='""'){
   
   pageObj.hideField('strtotime_end');
   
   var ctrlend = Runner.getControl(pageid, 'end');
   
   var ctrlstrtend = Runner.getControl(pageid, 'strtotime_end');
   
   var check = Runner.getControl(pageid, 'checkbox');
   
   ctrlend.on('blur', function() {
   
   // call 'setValue' method to set new value
   
   if(ctrlstart.getValue() != "" && ctrlend.getValue() != ""){
   
   var date1 = new Date(ctrlstart.getValue());
   
   var date2 = new Date(ctrlend.getValue());
   
   var numMonths = (date2.getFullYear() - date1.getFullYear()) 12 + (date2.getMonth() - date1.getMonth());
   
   if(date1.getDate() > date2.getDate())
   
   numMonths--;
   
   alert(numMonths + "");
   
   if(numMonths < 24)
   
   {
   
   check.setValue(true);
   
   pageObj.showField('strtotime_end');
   
   pageObj.showField('strtotime_start');
   
   }
   
   else
   
   {
   
   check.setValue(false);
   
   pageObj.hideField('strtotime_end');
   
   pageObj.hideField('strtotime_start');
   
   }
   
   ctrlstrtend.setValue(ctrlend.getValue()+"");
   
   }
   
   });
   
   } }
   Hope this helps someone!
