Question

我无法在类名称为 funding_status_hidden 的克隆隐藏复选框输入中更新 funding_status [0] 的名称属性。我可以使用下面的js脚本更新funding_status类的常规输入。它还按预期更新了许多其他复选框字段-努力更改最后一个复选框。

$(document).ready(function(){
var template = $('#products .product:first').clone();
var productsCount = $('.product').length-1; 

window.addProduct = function(){
    productsCount++;
    var product = template.clone().find(':input, .days').val('0').prop('checked', false).each(function(){

        var newId = this.id.substring(0, this.id.length-1) + productsCount;

        $(this).next(':input, label').attr('for', newId); // update label for
        $(this).next(".funding_status").attr('name', function() { return $(this).attr("name").substring(0, this.id.length-2) + "["+productsCount+"]" });
        $(this).next(".funding_status_hidden").attr('name', function() { return $(this).attr("name").substring(0, this.id.length-2) + "["+productsCount+"]" });


        this.id = newId; // update id and name (assume the same)



        $(this).find(".cloned_checkbox_hidden").attr("name", function() { return $(this).attr("name").substring(0, this.id.length-9) + "["+productsCount+"]" });
        $(this).find(".cloned_checkbox").attr("name", function() { return $(this).val('1').attr("name").substring(0, this.id.length-2) + "["+productsCount+"]" });




    }).end()
    .attr('id', 'product' + productsCount)
    .appendTo('#products');

}
$('.add').click(addProduct);
$("a#rp").click(function () {
    productsCount--;
if ($(".product").length != 1) {
$(".product:last").remove();
}
event.preventDefault();
});
});

克隆的Div的HTML（略微显示出我要更新的资金部分）

<div id="product2" class="product m-b-20">
<div class="field is-horizontal">
    <div class="field is-horizontal">
        <div class="field-body">

    </div>
</div>

Answer 1

使用

document.getElementById("input-id").name ="new name";

更改名称

并且不要在名称中使用[0]

使用这样的数据名称

<input data-name="array[0]" >

针对班级

var t = document.getElementById("cloned-data-container");

t.querySelector(".your-spacial-input-classname").name = "custom value";
