检测并使用相同的链接

Question

我将产品分为两部分：图像和描述。图像是使用链接，但描述不是。因为它是动态的，我想知道如何获取此URL并使用JS将其分配给描述框？

    <div class="item__media">
    <div class="item__image">
        <a href="http://prototype.aaa.com" title="" class="product-image item__link">
            <img src="http://a4.res.cloudinary.com//image/upload/c_pad,dpr_1.0,f_auto,h_221,q_80,w_303/damson_108170_1_2_2.jpg" alt="image">
        </a>
    </div>
    <div class="item__detail">
        <a href="http://prototype.aaa.com" title="Description" class="item__link">
            <p class="product-name item__name">Product 15252</p>
        </a>

</div> </div></div>
        <div class="price-box">
            <p class="old-price">
            <span class="price-label">Was</span>
            <span class="price" id="old-price-7139">
                                <span class="price"><span class="currency">£</span>179</span>            </span>
        </p>

        <p class="special-price">
            <span class="price-label">You Save</span>
            <span class="price" id="price-excluding-tax-7139">
                <span class="price"><span class="currency">£</span>90</span>            </span>
        </p>
    </div>

<div class="price-range">
            <span class="price-label" style="display: none;">From </span><span class="price-label">SHOP FROM</span>
        <span class="price"><span class="price"><span class="currency">£</span>89</span></span>
</div>
    </div>
</div>

谢谢N
