JQuery的

$("#submit").click(function() {
var $row = $(this).closest("tbody");   
var $text = $row.document.getElementById("#emulation").checked(); // 
alert($text);
});

Answer 1

从

更新

var $text = $row.document.getElementById("#emulation").checked();

到

var $text = $("#emulation").is(":checked");

使用JQuery获取复选框选中状态
