Question

I have a JSON file and I’m injecting the data into an HTML page.
I would like to filter out any empty object array that’s coming back from the JSON file.

My code is below – should I use GREP maybe?

  $(data.content).each(function(index, content){
      $("#htmlID").append('<span>' + content.myinfo + ');
    });
        {

        "content": 

        [ 
    {"myinfo":"Bill Clinton 095 years old. "},
    {" "},
    {"myinfo":"Bill Clinton 295 years old. "},
    {" "}

        ]
        }

Can’t you just ignore empty data? Something like this?

$(data.content).each(function(index, content){
    if(!(typeof content.myinfo === "undefined" ||
      content.myinfo.length<1)){
      $("#htmlID").append('<span>' + content.myinfo);
    }
});
