Using a list for navigation, I am looking for a clean way to apply the \'selected\' class to a list item if the page URL (minus anything after the path) matches the href of the
you can use indexOf()
$(document).ready(function () {
$('.leftNav li a').each(function(){
var ThisHref = ($(this).attr('href').split('?'))[0];
if(window.location.href.indexOf(ThisHref) > -1) {
$(this).closest('li').addClass('selected');
}
});
});
Example
var url = "http://www.website.com/index/p/clothing/bottoms/capris/N-10764?ab=leftNav:capris";
$(document).ready(function () {
$('.leftNav li a').each(function(){
var ThisHref = ($(this).attr('href').split('?'))[0];
//alert(ThisHref);
if(url.indexOf(ThisHref) > -1) {
$(this).closest('li').addClass('selected');
}
});
});
.selected{
background : red;
}
Explanation:
$(document).ready(function () { // run the code after document is ready
$('.leftNav li a').each(function(){ // loop through on -
// $(this).attr('href') will return href as string .. in your case will return something like '/p/clothing/dresses/N-10635?ab=leftNav:dresses'
// using .split('?') to separating this href string by '?'
// [0] get the first string after split (in this case it will be '/p/clothing/dresses/N-10635')
// combine all of those steps on just one line
var ThisHref = ($(this).attr('href').split('?'))[0];
// get the 'window.location.href' which is return your url ..something like 'http://www.website.com/index/p/clothing/bottoms/capris/N-10764?ab=leftNav:capris'
// try to find (first string after split) into (url/window.location.href)
if(window.location.href.indexOf(ThisHref) > -1) { // if the url contains the first string after split addClass
$(this).closest('li').addClass('selected');
}
});
});
you can read about .split() here
Note: in Vinas answer he use
this.href
which will return href as string .. in your case will return something like '/p/clothing/dresses/N-10635?ab=leftNav:dresses' and he use location.pathname and the code ofindexOf()
he try to find thelocation.pathname
into thehref
Additional: in your case both my answer and Vinas answer will work . that's not depending on code its depending on your case and what you're trying to do .. something like .hide(0) , .slideUp(0) , fadeOut(0)
all of those hide the element with same effect .. So the code always determine by the case you working with .. May be my code or even Vinas's code won't work on another case
