You did not inform the table structure, but no matter the structure, the code below will catch the id
of the column you indicate in the variable:
var coluna = 3; // coluna em que está o ID
The code goes through each row of the table and checks for a checkbox
marked; if there is, it will catch the id
of td
(column) reported in the variable above (var coluna
) and insert into the array var ids = [];
.
See example:
$(document).ready(function(){
var ids = [];
var coluna = 2; // coluna em que está o ID
$("table tr").each(function(){
if($(this).find("input[type='checkbox']").is(":checked")){
ids.push($(this).find("td:eq("+(coluna-1)+")").attr("id"));
}
});
console.log(ids);
});
