Question

so I’m parsing through a JSON object like so

if(val.function1!==""){
    $("#contentFunction").text(val.function1);
}

if(val.function2!==""){
    $("#contentFunction").text(val.function1 + "; " + val.function2);
}

if(val.function3!==""){
    $("#contentFunction").text(val.function1 + "; " + val.function2
        + "; " + val.function3);
}

I’m wondiering if there is a better way of checking if my json object property is empty instead of having tons of conditions… this gets really messy if for instance I have up to val.function10

Thanks for your help

Answer 1

var strs = [];
for (var i = 0; i < 10; i++) {
  var value = val["function" + i];
  value && strs.push(value);
}
$("#contentFunction").text(strs.join("; "));
