$("a").each(function() {
//Do your work
})

Use the anchor tag as selector
使用锚标签作为选择器
$("a").each(....)
回答by thecodeparadox
var links = [];
$('#mm a').each(function() {
links.push( this.href );
// output of links: ['http://www.google.com', 'http://www.dictionay.com']
// According to comment
// if you need each link separately then
// may try like
var href = this.href;
// now process with the href as you wish
});
for all as, change the selector #mm ato just a;
对于所有as，将选择器更改#mm a为 just a;

这就是我所期望的……谢谢你的回复
$("a").attr("clink","");
$(window).load(function(){
$("#mm a").attr("clink","");
$('#mm a').each(function(){
var hrefl=$(this).attr('href');
var clink=hrefl;
$(this).attr('clink',clink);
$(this).attr('href',"#");
});
});

If you want all the unique links on a page, borrowing from other answers on this page and Unique values in an array
如果您想要页面上的所有唯一链接，请借鉴此页面上的其他答案和数组中的唯一值
function onlyUnique(value, index, self)
{
return self.indexOf(value) === index;
}
function getAllLinks()
{
var links = [];
$("a").each(function ()
{
links.push(this.href);
});
return links.filter(onlyUnique);
}

You can just do $('a')this will return a collection of al the A elements on a page.
您可以这样做$('a')将返回页面上所有 A 元素的集合。
Then you can iterate over it with $('a').each(function(index, value){})
然后你可以迭代它 $('a').each(function(index, value){})
