});

my problem when click plus button in row number 1 dialog box appear (like image 2) image 2

but why when click plus button in row dialog box not appear, page reload , table gone.i want prompt dialog box whenever click 1 of pluss button. help?

the problem occurs when use duplicate identifiers, identifiers must unique. can add common css class can use class selector $('.classname')

html(simplified here) 

<input class="bt_tambah_calon_wisudawan" />

script

$(".bt_tambah_calon_wisudawan").click(function(){     var tr = $(this).closest('tr'),         value1 = tr.find('td:eq(1)').text(),         value2 = tr.find('td:eq(2)').text();      //rest of code });
