解决validate无法验证多个相同name的input

//用于生成uuid
    function S4() {
        return (((1 + Math.random()) * 0x10000) | 0).toString(16).substring(1);
    }

    function guid() {
        return (S4() + S4() + "-" + S4() + "-" + S4() + "-" + S4() + "-" + S4() + S4() + S4());
    }
//为动态添加的元素绑定事件
    $('#contentTable').on('click', '.addTable', function () {
        // var uuid = "qty" + guid();
        //步骤预设
