You had an Uncaught ReferenceError: i is not defined; I've updated your fiddle here:

你有一个未捕获的ReferenceError: i没有定义;我更新了你的小提琴:

http://jsfiddle.net/hxfsB/24/

$('#envoyer').click(function(e){
    var myArray = new Array(3);
    for ( var j = 0; j < 3; j++) { 
        var check=$('input:checkbox[name=checkbox'+j+']').is(':checked');
        if(check==true)
            myArray[j]=$('input:checkbox[name=checkbox'+j+']').val();

        // Alert Current Selection //
        alert('check ' + " " + myArray[j] );
    }    
});

Keep in mind: undefined means the checkbox is NOT selected.

记住:undefined意味着没有选中复选框。

You have an error when outputting myArray in alert (there is no i variable defined).

在alert中输出myArray时会出现错误(没有定义i变量)。

However, your code can be better structured. Here is one solution:

但是，您的代码可以有更好的结构。这里有一个解决方案:

$("#envoyer").click(function(e) {
    var myArray = [];
    $(":checkbox:checked").each(function() {
        myArray.push(this.value);
    });

    alert("Checked: " + myArray.join(","));
});​

The i in myArray[i] doesn't exist anywhere. You need to either put the alert inside the for loop and use myArray[j] or create a new for loop using i

myArray中的i在任何地方都不存在。您需要将警报放入for循环中并使用myArray[j]或使用i创建一个新的for循环
