[英]Get the href attribute for each link in a section of HTML
I've written the following jQuery to loop through each of the <a>
objects in a section of HTML: 我编写了以下jQuery,以遍历HTML部分中的每个
<a>
对象:
$(".chapterindex" + key + " div.link a").each(function(intIndex){
alert("Numbered index: " + intIndex);
});
});
The key value used in the first line of the jQuery is from an array of URL's I've built manually, something like this: jQuery第一行中使用的键值来自我手动构建的URL数组,如下所示:
var chapters = new Array();
chapters[0] = "original/html/0/ID0EFJAE.html";
I can alert the intIndex
which gives me, 0,1,2,3,4,5....
etc.. 我可以提醒
intIndex
给我0,1,2,3,4,5....
等。
But how can I extend the jQuery above to get the href
attribute from each of the links found in the HTML? 但是如何扩展上面的jQuery,以从HTML中找到的每个链接中获取
href
属性?
Try this: 尝试这个:
$(".chapterindex" + key + " div.link a").each(
function(intIndex){
alert( "Numbered index: " + intIndex );
var href = $(this).attr('href');
});
});
您可以通过$(this).attr('href')
访问它
$(".chapterindex" + key + " div.link a").each(
function(intIndex){
alert( "Numbered index: " + $(this).attr("href") );
});
});
$(".chapterindex" + key + " div.link a").each(function () {
alert(this.href);
});
Do you want the full HREF or the HREF as it appears in the tag? 您是否需要完整的HREF或标签中显示的HREF?
The jQuery object method $(this).attr('href')
proposed by some people will return whatever is set as the HREF attribute in the tag. 有人提出的jQuery对象方法
$(this).attr('href')
将返回标记中设置为HREF属性的任何内容。
The DOM node property method this.href
proposed by John will return the fully-qualified URL. John提出的DOM节点属性方法
this.href
将返回完全限定的URL。
So given a link <a href="/resources/foo.ext">Foo</a>
, the jQuery method will return "/resources/foo.ext" while the other method will return "http://mysite.ca/currentpath/resources/foo.ext". 因此,给定链接
<a href="/resources/foo.ext">Foo</a>
,jQuery方法将返回“ /resources/foo.ext”,而另一个方法将返回“ http://mysite.ca” /currentpath/resources/foo.ext”。
So it just depends on what you need returned. 因此,这仅取决于您需要退货的内容。
