How can I know what is going wrong with my Javascript in the Handler of fields?
Can I add anything to alert the error message out in the Javascript?
Million Thanks~!!!!!

Hi Mary,
Prior to CRM 2013, you would need to do this via JavaScript.

function calculate ()
{
var val1 = Xrm.Page.getAttribute(‘new_val1′).getValue();
var val2 = Xrm.Page.getAttribute(‘new_val2′).getValue();
if(val1==null)return;
if(val2==null)return;
var result = val1 + val2;
Xrm.Page.getAttribute(‘new_totalvalue’).setValue(result);
}
From CRM 2013, you could use Business Rules for the same.
From CRM 2015 onwards, Calculated fields were introduced.
Hope this helps.
How about if I am using the version before? Thanks!
Hi Mary,
From CRM 2015 onwards, a new Field Type is introduced called Calculated Field. You could use this field to find the sum of several fields instead of writing Javascript for the same.
See: http://www.powerobjects.com/2014/11/17/calculated-fields-in-dynamics-crm-2015/
If you need javascript itself, try the code below.
function calculate ()
{
var val1 = Xrm.Page.getAttribute(‘new_val1′).getValue();
var val2 = Xrm.Page.getAttribute(‘new_val2′).getValue();
if(val1==null)return;
if(val2==null)return;
var result = val1 + val2;
Xrm.Page.getAttribute(‘new_totalvalue’).setValue(result);
}
Hope this helps.
Alex, may I know how to calculate the sum of several fields by a Javascript Function? How to add more than one parameter and calculate the sum? Thanks!
Thanks Alex, will the script stop running if I add alert to it?
Hi,
there is some info here:
crmbook.powerobjects.com/.../debugging-javascript-libraries
In short,
- add alert("message"); to your javascript to display a popup message
- use F12 button to open dev tools in IE/chrome
- add debugger; command anywhere in your javascript to make the script stop there (this works when you are using F12 from above)
