onChange client script triggered twice

[dan_cooper]

My script resets the value of the field to null if the server returns a negative result, and it appears that that reset is causing the onChange function to be triggered again.   Anyone else have this problem?   Any suggestions to resolve?

Hi Daniel ,

I am assuming that this Client script is onChange of field "u_cost_object". If this is the case then:

function onChange(control, oldValue, newValue, isLoading) {

      if (isLoading){

              return;

      }

// below line added to check onChange and newValue is not blank and null

if(!isLoading && newValue != '' || newValue != null){

  var costInfo = checkSAPInfo();

  var costObject = g_form.getValue('u_cost_object');

  var deptID = g_form.getReference('u_requesting_department');

  var deptNumber = deptID.name;

  if (costObject!='' && deptNumber!=''){

  if (costInfo != "true"){

  alert("This is not a valid cost object.   Please contact your business officer to obtain a valid cost object.");

  g_form.setValue('u_cost_object','');

  }

  else{}

  }

}

}

...

function

You can refer Client Scripts - ServiceNow Wiki for more clarity

Please mark answer correct if it was really helpful.

Thanks,

Thanks Darshan,

Unfortunately that doesn't seem to resolve the issue - the checkSAPInfo() function is still being called twice.

Thanks for your help,

Dan

Hi Daniel,

Minor change in Darshan Rathod's code.

if(!isLoading && newValue != null && newValue != '' ) {

//rest of the code

}

Thanks

EDIT : is u_cost_object a boolean field? In that case you can set it to "false" and make changes in above conditions accordingly.

Ah hah!   That seems to have done the trick.   Thanks so much Mandar!
