How to Populate jQuery Object with Data from Link Inside HTML List?
I have a list that looks like this:
<ul id="theLinks">
<li><a href="one.php">One</a></li>
&l开发者_运维技巧t;li><a href="two.php">Two</a></li>
<li><a href="three.php">Three</a></li>
<li><a href="four.php">Four</a></li>
</ul>
I would like to populate a jQuery Object with the data from that list so it looks like this:
var Links = {
'One' : 'one.php',
'Two' : 'two.php',
'Three' : 'three.php',
'Four' : 'four.php'
}
What is the best method for solving this problem?
Thanks in advance!
var Links = {};
$('#theLinks li a').each(function(){
Links[this.innerHTML] = this.href.substring(this.href.lastIndexOf("/") + 1);
});
Fiddle link
Note: the links will not be in order because this is not an array.
Outputs:
Four: "four.php"
One: "one.php"
Three: "three.php"
Two: "two.php"
Not tested, but something like this:
var Links = {};
$('#theLinks li a').each(function(index, value) {
Links[value.text()] = value.attr('href');
});
var obj = {};
$("#theLinks a").map( function() {obj[$(this).text()] = this.href });
alert(obj.One);
alert(obj.Two);

Your result isn't an array, it's an object. (And it's nothing to do with jQuery, it's a straight JavaScript object. :-) )
Here's how you'd do that:
var Links = {};
$('#theLinks > li > a').each(function() {
var $this = $(this);
Links[$this.text()] = $this.attr('href');
});
Live example
Note I've used a fairly restrictive selector, #theLinks > li > a
(an a
only when it's the direct child of an li
only when it's the direct child of #theLinks
). You could use a looser one if your structure may vary slightly, such as #theLinks li a
which allows for intermediate elements between both the ul
and the li
s and between the li
s and the a
s. It depends entirely on what you want to achieve. But with the markup you gave, I'd probably be fairly tight about it.
