        $(document).ready( function() {
            $("#checkall").click(function() {
                if ($(this).is(':checked')){
                    $(":checkbox").attr("checked", true);
                  }
                  else{

Answer 1

执行此操作以获取名称

更改添加复选框功能（否则您没有任何值）：

newTextBoxDiv.after().html('<input type="checkbox" value="' + cars[i] + '" />'+cars[i]+'</br>');

更新你的if else：

       var isChecked = $('[type=checkbox]:checked');
       var names = "";
         isChecked.each(function(){
             names += $(this).val();
         });
       alert(names);

查看jQuery的serialize()

console.log($(":checked").serialize());

Answer 3

我知道你有答案，但这解决了几个问题：小提示显示它有效：http://jsfiddle.net/WGKuX/

标记：修复</br>的错误html并从标记中删除onclick（稍后在代码中）

<br />
<div id="TextBoxesGroup">
    <div id="TextBoxDiv1">
        <input type="checkbox" id="checkall" value="check" />select
        <br />
    </div>
</div>
<input type="button" value="GetName" id="button" />

现在有些代码：对每个部分的评论

var counter = 1;
var cars = ["Paul", "Catherine", "Steve", "Paul", "Catherine", "Steve", "Paul", "Catherine", "Steve", "Paul", "Catherine", "Steve"]; //change to simpler declaration

$(document).ready(function () {
    $("#checkall").click(function () {
        $(".myCars").prop("checked", $(this).is(':checked'));
    }); // simplify
    $("#TextBoxesGroup").on("change", ".myCars", function () {
        $("#checkall:checkbox").prop("checked", ($(".myCars").length == $(".myCars:checked").length));
    }); // assume "select" means "select all", if all are checked, check the select otherwise uncheck
    var mylist = "";
    var i = 0;
    for (i = 0; i < cars.length; i++) {
        mylist += "<div id='TextBoxDiv" + (counter + i) + "'><input class='myCars' type='checkbox' value='" + cars[i] + "' />" + cars[i] + '<br /></div>';

    }// note the class added to the checkboxes
    $(mylist).appendTo("#TextBoxesGroup"); // simplify the insertion, only hit DOM once
});

$('#button').click(checkState); //event handler moved from markup

function checkState() {
    var names = "";
    // build list based on the seleck all check state
    var checkslist = $('#checkall').prop('checked') ? $('.myCars[type=checkbox]') : $('.myCars[type=checkbox]:checked');
    checkslist.each(function () {
        names += $(this).val();
    });
    alert(names);
}

使用jquery显示选中的复选框数据
