jQuery更改父图片的data-src

Question

我有以下html构造函数，内容是动态添加的

<div class="media text-muted pt-3">
    <img data-src="holder.js/32x32?theme=thumb&bg=d32f2f&fg=d32f2f&size=1" alt="todo" class="mr-2 rounded">
    <div class="media-body pb-3 mb-0 small lh-125 border-bottom border-gray">
        <div class="d-flex justify-content-between align-items-center w-100">
            <strong class="text-gray-dark">{{ $ticketValue->title }}</strong>
        </div>
        <br>
        <div class="d-flex justify-content-between align-items-center w-100">
            <span class="d-block">
                <strong>Erstellt von {{ $ticketValue->description }}</strong>
            </span>
            <button type="button" class="closing-ticket" data-ticket-id="{{ $ticketValue->id }}">
                <i class="fas fa-check"></i>
            </button>
        </div>
    </div>
</div>

如果用户单击按钮，我想更改当前父图像标签的data-src。 到目前为止，我已经做到了：

this.closingTicket.click((e) => {
    let _this = $(e.currentTarget);
    axios.post('ticket/close/' + this.elements.closingTicket.attr('data-ticket-id'))
        .then((response) => {
            _this.hide(); // hides buttons
            // trying to find the image and change its data-src
            _this.parent().parent().parent().find('img').data('src', 'holder.js/32x32?theme=thumb&bg=64dd17&fg=64dd17&size=1');
        })
        .catch((error) => {
            // error
        })
});
