Question

I am trying to get the substring from a variable when the content length is longer than 120 chars.

$.ajax({
          url: url,
          dataType: 'json',
          async: false,
          success: function(data){
              $.each(data, function(i, item) {
                      var name = item.name;
                      var itemId = item.itemId;

                    if(name.length >= 120) {
                        selectHTML += '<option value=' + itemId + '>' + name.substr(0, 120) + '</option>';
                      } else {
                      selectHTML += '<option value=' + itemId + '>' + name + '</option>';
                    }
            });
          }
    });

But as a result, I always get this:

name is undefined

When I do it without substring(), it works without problems. Any suggestions?

Edit:
Error is thrown on this line:

if(name.length >= 120) {

Answer 1

Try changing if (name.length >= 120) to if (name && name.length >= 120)
