javascript - 将所有包含图像的链接更改为 : javascript(alert(thehref));

Question

将所有包含图像的链接更改为:javascript(alert(thehref));

例如。

<a href="/galleries/anna-leah-111827/image01.html"><img src="/source_galleries/anna-leah-111827/tn/01.jpg"></a>
<a href="/galleries/23435/image01.html">ssss</a>

变成了

<a href="/galleries/anna-leah-111827/image01.html" onclick="alert(this.href)"><img src="/source_galleries/anna-leah-111827/tn/01.jpg"></a>
<a href="/galleries/23435/image01.html">ssss</a>

如何将其作为使用外部 JavaScript 文件的书签来实现。

我已经尝试了一整天了，但没有成功。

Answer 1

for (var i= document.links.length; i-->0;) {
    if (document.links[i].getElementsByTagName('img').length!=0) {
        document.links[i].onclick= function() {
            alert(this.href);
        };
    }
}

编码为小书签:

javascript:for%28i%3Ddocument.links.length%3Bi--%3E0%3B%29if%28document.links%5Bi%5D.getElementsByTagName%28%27img%27%29.length%21%3D0%29document.links%5Bi%5D.onclick%3Dfunction%28%29%7Balert%28this.href%29%3B%7D%3Bvoid%280%29%3B
