恢复数据表

Question

我在此链接enter link description here

上提供了我需要的示例

检索代码

var totalRows = $('#tblCatalogo tbody tr').length;
for(var i=1; i<=totalRows;i++){
    var rs = $('#tblCatalogo tbody tr').children().data('cod');
    $('#result').append(rs);
}

Answer 1

Fiddle Demo

.map()

$(function () {
    var rs = $('#tblCatalogo td [data-cod]').map(function () { //.map creates array
        return $(this).data('cod'); //return data-cod value
    }).get().join(); //.get() to get array and .join() to convert array to string joined with comma
    $('#result').append(rs);
});

$('#tblCatalogo td [data-cod]')在data-cod内选择属性为td的元素，该元素位于ID为tblCatalogo的元素内

Answer 2

$(function(){    $('#tblCatalogo tbody tr').find("span[data-cod]").each(function (){

    $('#result').append($(this).data("cod"));
    });
});
