jQuery: Get title and href values as variables
提问by Meek
I have a list of links with a title and a href value. I would like to be able to get these values seperately, but I always get the first link's values. Why is that? See my fiddle here. As you can see - when clicking a any of the link, you always get the values from the first link. I guess setting these variables isn't sufficient:
我有一个带有标题和 href 值的链接列表。我希望能够单独获得这些值,但我总是获得第一个链接的值。这是为什么? 在这里查看我的小提琴。如您所见 - 单击任何链接时,您始终会从第一个链接获取值。我想设置这些变量是不够的:
var title = $('.mg_phones').attr('title');
var url = $('.mg_phones').attr('href');
Any ideas?
有任何想法吗?

You have to refer to the clicked element:
你必须参考被点击的元素:
var title = $(this).attr('title');
var url = $(this).attr('href');

You need to change the code to this:
您需要将代码更改为:
var title = $(this).attr('title').toLowerCase();
var url = $(this).attr('href');

Use $(this)
instead. The issue was that $('.mg_phones')
is an array of all elements with that class and accessing $('.mg_phones').attr(...)
would pick the first element as it doesn't know which of them you want.
使用$(this)
来代替。问题是这$('.mg_phones')
是一个包含该类的所有元素的数组,访问$('.mg_phones').attr(...)
将选择第一个元素,因为它不知道您想要哪个元素。
But $(this)
refers to the currently clicked item in this context.
但$(this)
在此上下文中指的是当前单击的项目。
$('.mg_phones').click(function (event) {
event.preventDefault();
var title = $(this).attr('title').toLowerCase(); //this changed
var url = $(this).attr('href'); //this changed
if (title.length != 0) {
$('#test').text(title + ": " + url);
}
