数组内的Json Array

Question

I'm fetching data from a server. The output is in JSON.

$.ajax({
    type: 'POST',  
    data: ({category : inpval}),
    dataType: 'json',
    url: 'php/projects.php',
    success: function(data) {
       for(var i=0; i<data.length; i++){
          $('#project-grid').append('<p>' + data[i].project + '</p><img src="img/'+data[i].images+'">');
       }
    }
});

But data[i].images return an array:

image01.jpg,image01a.jpg,image02.jpg

How I loop this array inside the main array?

Ideally, you don't want to call append() multiple times. It slows things down. It's better practice to create your HTML and append it all in one go.

var toAppend = '', images;
for(var i = 0; i < data.length; i++){
  toAppend += '<li><p>'+ data[i].project +'</p>';
  images = data[i].images.split(',');
  for(var j = 0; j < images.length; j++){
    toAppend += '<img src="img/'+images[j]+'" />';
  }
  toAppend += '</li>';
}
$('#project-grid').append(toAppend);
