How to limit data in a single cell of DataTable
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;
}
}
jquery datatable

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="">'
})
