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
。
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");
