Question

我正在尝试获取每个CID的{{1}}，并将每个.vehicleID附加到href类.vehicle-actions

&VID=[CID]

在我的脑海里，这似乎很简单，但我似乎无法理解我做错了什么

的jQuery

<ul>
            <li><a href="./garage_vehicle.php?mode=add_vehicle"><span>Create a Vehicle</span></a></li>

            <li class="vehicle-view toggleVehicleButton"><a class="vehicleID" href="./garage_vehicle.php?mode=view_own_vehicle&amp;CID=6"><span>2014 Audi A4</span></a>
                <div class="vehicle-actions" style="width: 179px; display: none;">
                    <ul>

Answer 1

您查看a.vehicleID元素，但应查看其父li。

您的代码可以简化。我会这样做：

$('.vehicleID').each(function(i, val){
    var CID = getURLParameter(this.href, 'CID');
    $('.vehicle-actions a', $(this).closest('li')).attr('href', function(_, href){
         if (href.indexOf("&VID")!=-1) return href; 
         return href + '&VID=' + CID);
    });
});

在简化中，我更喜欢this.href而不是$(this).attr('href')，我使用the version of the attr function taking a function as second parameter。

Answer 2

此piece代码可能无效，

$('.vehicle-actions',this).each(function(i, val){
    editCID = $(this).find('a');
    editCID.attr('href', editCID.attr('href') + '&VID=' + CID);
});

在$('.vehicle-actions',this)中，这不会识别下一个div.vehicle-actions，因为它不是a子项，因此请将其closest li.vehicle-view用作父选择器

试试这个，

$('.vehicle-actions',$(this).closest('li.vehicle-view')).each(function(i, val){
    editCID = $(this).find('a');
    editCID.attr('href', editCID.attr('href') + '&VID=' + CID);
});

Answer 3

您尚未在所有代码中指定vehicleID，因此以下语句将仅返回一个元素。

$('.vehicleID').length

所以在所有标签中正确添加类。

jQuery在每个循环中更改每个子节点的链接
