    <script type="text/javascript" src="../js/jquery_1.9.0.js"></script>

       <script>
       var counter = 1;
       var cars = new Array("Paul","Catherine","Steve","Paul","Catherine","Steve","Paul","Catherine","Steve","Paul","Catherine","Steve");

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

                    $(":checkbox").attr("checked", false);
                  }
            }); 

            // Uncheck All

            for (var i=0;i<cars.length;i++){
            var newTextBoxDiv = $(document.createElement('div'))
            .attr("id", 'TextBoxDiv' + counter);
             newTextBoxDiv.after().html('<input type="checkbox" />'+cars[i]+'</br>');

执行此操作以获取名称

更改将复选框功能添加到（否则您将没有任何值）：

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

更新您的 if else：

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

看看 jQuery 的serialize()

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

我知道你有一个答案，但这解决了几个问题：小提琴显示它工作：http: //jsfiddle.net/WGKuX/

标记：修复错误的 html</br>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" />

现在看一些代码：每个部分的注释

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);
}
