Question

I have a table tag on my page. I’m adding dynamically a new set of rows, where some of them can contain a <button class="btn btn-primary"></button> tag. I’m wondering, how to check the information via JQuery, if that table contains any rows with that button ?

Answer 1

Just try:

var buttons = $table.find('.btn.btn-primary');
var buttonExists = buttons.length > 0;

Table has to be a jQuery object containing your table.
