How to limit data in a single cell of DataTable












1















I have DataTable version 1.10.12 and I want to display only images in one cell of particular row. There are many images in database but I only want to show 2 images.



How can I achieve this?

How to set limit in forEach loop?



This is my code:



{
data: 'plays', name: 'plays', "defaultContent": "",
render: function (data, type, row, meta) {
var plays = '';
data.forEach(function (item) {
plays += '<img class="img" src="/images/theme/image_placeholder.jpg" alt="">'
})
return plays;
}
}

          The forEach method has an aditional parameter that gives you the iteration index:



          arr.forEach(function callback(currentValue, index, array) {
          // Your code
          }[, thisArg]);


          So you can simply check if index is greater than 1 to have only 2 iterations:



          data.forEach(function (item, index) {

          // Add this
          if (index > 1) {
          return;
          }

          plays += '<img class="img" src="/images/theme/image_placeholder.jpg" alt="">'
          })
