Javascript 代码从不通过$。每个（元素，…）（$。每个周期从不被调用）

我制定了以下代码：

function iterateChoices(row, element, choices, counter) {
    if ($.isArray(choices) && choices.length > 0) {
        element.each(function(index, item) {
            if (counter === 0) {
                row = '<div style="display:inline-block"><label style="display: inline-block">UPC:</label> <input style="display: inline-block" type="text" value="" name="pupc[]" /></div>';
                row += '<div style="display:inline-block"><label style="display: inline-block">Precio:</label> <input style="display: inline-block" type="text" value="" name="pprice[]" /></div>';
                row += '<div style="display:inline-block"><label style="display: inline-block">Cantidad:</label><input type="text" style="display: inline-block" value="" name="pqty[]" /></div>';
            }

            iterateChoices(row + '<div style="display:inline-block"><input style="display: inline-block" disabled="disabled" value="' + item.value + '"></div>', choices[0], choices.slice(1), counter + 1);
        });
        console.log("Counter: " + counter);
        console.log("Row: " + row);
    } else {
        html_temp = "";
        element.each(function(index, item) {
            html_temp += row + '<div style="display:inline-block"><input  style="display: inline-block" value="' + item.value + '" disabled="disabled"></div><br>';
        });
        html += html_temp;
    }
    console.log("html_temp: " + html_temp);
}

这是每个

console.log（）的输出：

真的不知道它在哪里失败了
你正在做的是
$.inArray（选项）
，然后是
$.each（元素）
。为什么？如果你
console.log（行）
或
console.log（html_temp）
在
每个
之后，你看到了什么？计数器的值是多少？你的第一个循环只有在
计数器==0的情况下才能“工作”{.@Reynier在每个
中的第一行放置一个
控制台.log
或
警报
-在停止创建元素时可能会出现其他问题。只需先用一个简单的调试语句测试循环是否被输入即可。@Reynier可以设置吗？我可以看到它正在控制台中被记录，但我看不到您实际在哪里将结果输出到DOM？您没有返回任何内容？。。。
