如何获取列表内的所有链接? [英] How to get all the links of a list inside a div?
问题描述
我有一个包含以下DOM树的代码:
I have a code with the following DOM Tree:
<div id="blogPagination">
<div class="pagination">
<ul>
<li>
<a href="/2" >1</a>
</li>
<li>
<a href="/3" >2</a>
</li>
</ul>
</div>
</div>
我试图达到我的标签的href。
I'm trying to reach the href of my tag. I can't reach it with anything I tried.
使用jQuery达到最佳方法是什么?
What's the best way to reach it with jQuery ?
我试过:
console.log($('#blogPagination div ul> li a')。 attr(href));
console.log($('#blogPagination> a') .attr(href));
$('#blogPagination')。 )
console.log($('#blogPagination div ul li a')。attr(href ));
没有运气..
感谢
编辑:
在nbrooks的回答之后,这里是我迄今为止所尝试的:
After nbrooks's answer, here is what I tried so far:
function bindPagination() {
console.log("bind");
$(function() {
var links = $("#blogPagination ul a").map(function(e) {
e.preventDefault();
return this.href;
}).get();
console.log(links);
});

考虑到Syfaro的答案,我也试过:
Considering Syfaro's answer, I've also tried :
$('#blogPagination').find('a').each(function(e) {
e.preventDefault();
console.log($(this).attr('href'));
});
没有运气。

我想提供更多有关此功能的详细信息,这些功能可能会产生重大影响:
EDIT 3 : I'd like to give more details concerning this function that may have a significant impact after all:
加载此分页,我使用Ajax和把手包装成一个文档就绪功能:
to load this pagination, I'm using Ajax and handlebars wrapped into a document ready function:
$(document).ready(function(){
// Get the customer service stats
var Content = {
init: function() {
/* this.getHomePosts(); */
this.getBlogPosts();
},
getBlogPosts: function(offset) {
if(offset == undefined){
offset = 0;
}
// GET the events with JSON
$.ajax({
type: "POST",
data: {},
url: site_url+"/main/blog/"+offset,
dataType: "json",
success: function(results) {
posts = results["posts"].map(function (blogContent) {
if( blogContent.picture != '' ) {
return {
Title: blogContent.title ,
Picture: Content.urlPostPic + blogContent.picture ,
Video: '' ,
Text: blogContent.text ,
Datetime: blogContent.datetime ,
}
} else {
return {
Title: blogContent.title ,
Picture: '' ,
Video: blogContent.video ,
Text: blogContent.text ,
Datetime: blogContent.datetime ,
}
}
});
pagination = {pagination: results["pagination"]};
var template = Handlebars.compile( $('#templateBlog').html() );
$('#blogPosts').append( template(posts) );
var template = Handlebars.compile( $('#templatePagi').html() );
$('#blogPagination').append( template(pagination) );
// Here we call bindPagination <===
bindPagination();
}
});
},
};
Content.init();
您可以在获取BlogPosts函数中看到我称之为BindPagination,这应该是这个功能,阻止默认行为并根据偏移量调用内容(分页系统)
You can see in the get BlogPosts function that I call BindPagination which is supposed to be this function, to prevent default behavior and call the content depending of the offset (pagination system)
function bindPagination() {
console.log("bind");
var links = $("#blogPagination ul a").map(function(e) {
e.preventDefault();
return this.href;
}).get();
console.log(links);
$('#blogPagination').find('a').each(function(e) {
console.log("clicked !");
e.preventDefault();
console.log($(this).attr('href'));
// var attr = this.attr();
// var id = attr.replace("/","");
// $('#blogPosts').empty();
// $('#blogPagination').empty();
// Content.getBlogPosts(id);
});
}
});
最后一个});
推荐答案
$('#blogPagination').find('a').attr('href');
这应该会查找所有 a
指定区域,得到它们的 href
,假设你已经有jQuery和所有好的东西设置了。
This should find all a
elements in the specified area, the get the href
of them, assuming that you've already got jQuery and all that good stuff set up.
如果您有多个 a
元素,则可以执行以下操作:
If you have multiple a
elements, you could do something like this:
$('#blogPagination').find('a').each(function() {
console.log($(this).attr('href'));
});
这将打印出每个 href
a
div
。
如果您需要阻止链接更改页面,您需要向 a
元素添加点击处理程序。
If you need to prevent the link from changing the page, you need to add a click handler to the a
elements.
$('#blogPagination').on('click', 'a', function(e) {
e.preventDefault();
console.log($(this).attr('href'));
});
这将阻止用户被带到链接,并获得 href
的链接点击。
This will prevent the user from being taken to the link, and get the href
of the link when clicked.
这是你想要的吗?
