Question

Let s suppose I have a page in which I d like to append a parameter (for example ?name=fc) to each and every url (also images etc.).

我试图用reg子做这件事,但似乎不可行(即,页上的联系不会改变)。

我的法典

var txt = document.documentElement.innerHTML;
var exp = "/((https?|ftp|file)://[-A-Z0-9+&@#/%?=~_|!:,.;]*[-A-Z0-9+&@#/%=~_|])/ig" ;
document.documentElement.innerHTML =( txt.replace(exp, "$1?name=fc"));

我的 Java本知识几乎是零,因此与我一样。

因此,问题在于, Java语有什么错误?

Answer 1

//loop 1: change links <a href="..."
var links = document.getElementsByTagName( a );
for(var i = 0, len = links.length; i < len; ++i)
   links[i].href = links[i].href + "?name=fc";

//loop 2: change images <img src="..."
var imgs = document.getElementsByTagName( img );
for(var i = 0, len = imgs.length; i < len; ++i)
   imgs[i].href = imgs[i].href + "?name=fc";

//loop 3: change image maps <area href="..."
var areas = document.getElementsByTagName( area );
for(var i = 0, len = areas.length; i < len; ++i)
   areas[i].href = areas[i].href + "?name=fc";

如,Mike Lewis/a>在替代loop 1和3的其他答复中具体指明。您可以用自己的回答书写一个单行,但仍需要<代码>loop 2,用于图像src。

Answer 2

for(var i = 0; i < document.links.length; i++) {
 document.links[i].href += "?name=fc"
}
