使用hiddenfield-value作为asp-route-parameter [英] Use hiddenfield-value for asp-route-parameter

问题描述

我在_PartialView中有一个具有我想要的值的隐藏字段(jQuery将其填满)我需要在(foreach)asp-route-parameter中使用相同的值

Ive got a hidden field in a _PartialView with the value I want (jQuery fills it up) I need this same value in a (foreach) asp-route-parameter

<div class="js-products-list">
 <input id="cropIdForProdBaseJQ" type="hidden" value="" />
  @foreach (var product in Model.Products)
  {
    <a asp-controller="XXX" asp-action="YYY" asp-route-language="@Model.CurrentLanguage" asp-route-cropId="" id="productCard">
  }

因此，asp-route-cropId应该从hiddenfield中获取值，并将其作为参数传递

So, asp-route-cropId should get the value from the hiddenfield, to pass it along as parameter

我尝试使用jQuery函数(没有任何运气)，例如

I tried using a jQueryfunction (without any luck) like

var neededValue = the value I got from another jQfunction
$('#productCard').attr("asp-route-cropId", neededValue);

可以做到吗?
我将如何处理?谢谢！

Can it be done?
How would i approach this? Thanks!

推荐答案

通过在a-tag中添加data-producttypeId来解决此问题；将productCard从"id"更改为"class"

Solved this by adding a data-producttypeId in the a-tag; changed productCard from 'id' to 'class'

@foreach (var product in Model.Products)

{
<a asp-controller="XXX" asp-action="YYY" asp-route-language="@Model.CurrentLanguage" asp-route-cropId="" class="productCard" 
data-producttypeId="@product.ProductTypeId">
}

我添加了一个jQuery函数:

I added a jQuery function:

$('.productCard').click(function(e) {    
var cropId = $('#croptype-filter-From-ProductType').val();

var clickedCard = $(this);
var baseUrl = clickedCard.attr("href");

var newUrl = baseUrl.replace("crop-ID", cropId);
window.location.href = newUrl;
});

替换字符串会创建一个新字符串，而不是实际替换它.将新创建的字符串放入href中后，一切都很好！感谢您的投入，给了我一些很好的线索！

A replace on a string creates a new string instead of actually replacing it. After placing the newly created string in the href, all was good! Thanks for the input guys, gave me some good leads!
