how to check if the object attribute value is NOT NULL

In my test script i have a object period_name which has multiple Item.I just want to fetch the textContent of these items

 

period_name.Item(k).textContent

 

However when running the test case i have noticed sometimes it returns the error that the object is NULL

 

I want to be able to check if the object attribute has a value or not before using it as follows:-

 

do {
                Indicator.PushText("Period Name is NULL")
     }while ( Check to see if object is still NULL)

 

var prd_name = period_name.Item(k).textContent

    Hi,

     

    You have not given any specific type of object that you want to check. But,

     

    you can check using below stuff, yourObject will be period_name.Item(k)

     

    do {
                Indicator.PushText("Period Name is NULL")
     }while (yourObject != null)

      Thanks shankar and any idea how to check if attribute value is NULL or NOT?

       

      var period = Aliases.browser.FindChild("Name", 'Panel("tabPeriod")', 99);

      var period_name = period.getElementsByClassName("dxtc-link");

       

      period_name.Item(k).textContent

        Hi,

         

        It's pretty simple,

         

        function test()
{
    var period = Aliases.browser.FindChild("Name", 'Panel("tabPeriod")', 99);
    var period_name = period.getElementsByClassName("dxtc-link");
 
    do
   { //blah blah}while(    period_name.Item(k) != null)

   if(period_name.Item(k).textContent != null)
   {
      Log.Message("It is not null")
   }
  else
  {
      Log.Error('It is null")
   }
}
