So i'm having some issues with my JQuery which is suppose to scroll to particular divs.
HTML
<div id="searchbycharacter">
<a class="searchbychar" href="#" id="#0-9" onclick="return false">0-9 |</a>
<a class="searchbychar" href="#" id="#A" onclick="return false"> A |</a>
<a class="searchbychar" href="#" id="#B" onclick="return false"> B |</a>
<a class="searchbychar" href="#" id="#C" onclick="return false"> C |</a>
... Untill Z
</div>
<div id="0-9">
<p>some content</p>
</div>
<div id="A">
<p>some content</p>
</div>
<div id="B">
<p>some content</p>
</div>
<div id="C">
<p>some content</p>
</div>
... Untill Z
JQuery
What i want the code to do is: On click event of an .searchbychar A TAG > Take the ID attributes value and scroll to that...
$( '.searchbychar' ).click(function() {
$('html, body').animate({
scrollTop: $('.searchbychar').attr('id').offset().top
}, 2000);
});
This question is related to
javascript
jquery
html
parsing
Ids are meant to be unique, and never use an id that starts with a number, use data-attributes instead to set the target like so :
<div id="searchbycharacter">
<a class="searchbychar" href="#" data-target="numeric">0-9 |</a>
<a class="searchbychar" href="#" data-target="A"> A |</a>
<a class="searchbychar" href="#" data-target="B"> B |</a>
<a class="searchbychar" href="#" data-target="C"> C |</a>
... Untill Z
</div>
As for the jquery :
$(document).on('click','.searchbychar', function(event) {
event.preventDefault();
var target = "#" + this.getAttribute('data-target');
$('html, body').animate({
scrollTop: $(target).offset().top
}, 2000);
});
You can do this:
$('.searchbychar').click(function () {
var divID = '#' + this.id;
$('html, body').animate({
scrollTop: $(divID).offset().top
}, 2000);
});
F.Y.I.
. (dot) like in your first line of code.$( 'searchbychar' ).click(function() {$('.searchbychar').attr('id') will return a string ID not a jQuery object. Hence, you can not apply .offset() method to it.Here is my solution:
<!-- jquery smooth scroll to id's -->
<script>
$(function() {
$('a[href*=\\#]:not([href=\\#])').click(function() {
if (location.pathname.replace(/^\//,'') == this.pathname.replace(/^\//,'') && location.hostname == this.hostname) {
var target = $(this.hash);
target = target.length ? target : $('[name=' + this.hash.slice(1) +']');
if (target.length) {
$('html,body').animate({
scrollTop: target.offset().top
}, 500);
return false;
}
}
});
});
</script>
With just this snippet you can use an unlimited number of hash-links and corresponding ids without having to execute a new script for each.
I already explained how it works in another thread here: https://stackoverflow.com/a/28631803/4566435 (or here's a direct link to my blog post)
For clarifications, let me know. Hope it helps!
