如何使用FF扩展名用.jpg屏蔽url?
原标题:How to block urls with .jpg using FF extension?

我正在创建一个FF插件。我想阻止页面中所有带有.jpg(或任何其他用户定义的扩展名)的URL。

怎么做??

问题回答

根据URL推测,您的意思是<;a>元素,则下面的代码将删除所有以这些扩展名结尾的jpg/gif/png链接。如果要将其更改为图像,可以将搜索的元素从a更改为img,并将搜索测试从href改为src

jsfiddle

var m = document.getElementsByTagName("a");

    var patt = new RegExp("^https?://(?:[a-z-]+.)+[a-z]{2,6}(?:/[^/#?]+)+.(?:jpg|gif|png)$","i");
    var removed = 0;
    for (i=0; i<m.length;){
        if (patt.test(m[i].href)){
            // it got matched, remove it
            m[i].parentNode.removeChild(m[i]);
            removed++;
        }else{
            i++;
        }

    }
    alert(removed+" image url s removed");
