jquery操作checkbox
//全选/取消全选 $('#quanxuan').toggle(function () { $("input[name='abc']").attr("checked", 'true'); }, function () { $("input[name='abc']").removeAttr("checked"); }); 一句话搞定: $("#headbox").click(function() { $(":checkbox").prop('checked', $(this).prop('checked')); }); //反选 $('#fanxuan').click(function () { $("input[name='abc']").each(function () { if ($(this).attr("checked")) { $(this).removeAttr("checked"); } else { $(this).attr("checked", 'true'); } }); });
jquery版本在1.3之前时,获取checkbox的选中项的操作:
$("input[name='abc'][checked]").each(function () { alert(this.value); });
jquery版本在1.3之后时,获取checkbox的选中项的操作:
$("input[name='abc']:checked").each(function () { alert(this.value); });
