NavScroll
NavScroll is a simple jQuery plugin for animated scrolling to a section of your page. It also features mobile dropdown support so if your navigation transforms into a dropdown on a certain breakpoint, navScroll hides the dropdown after a click.
Demo
There's a demo included with this package. It's an example of navigation I use a lot, so feel free to use it yourself!
You can also checkout the demo here: jhammann.github.io/jquery-navScroll/demo/
Setup
Include a recent version of jQuery and the navScroll plugin inside your page.
<script src="http://code.jquery.com/jquery-1.11.0.min.js"></script>
<script src="jquery.navScroll.js"></script>
<script>
// To attach navScroll to an element without mobile dropdown support
$('.nav').navScroll();
// Or you can enable mobile dropdown support and give it a custom breakpoint (defaults to 1024)
$('.nav').navScroll({
mobileDropdown: true,
mobileBreakpoint: 768
});
</script>Install using bower
Optionally, you can install jquery-navScroll with bower if you prefer:
bower install jquery-nav-scrollOptions
| Name | Description | Type | Default |
|---|---|---|---|
scrollTime |
The time it takes to scroll to the element in milliseconds (set this to 0 so it obviously won't show an animation). | Integer | 500 |
navItemClassName |
The class of the items which invokes the scroll animation. All anchor tags inside the element are clickable when the value is empty. | String | '' |
navHeight |
Set the height of the navigation (to use as offset). 'auto' let's the plugin determine the height automatically, a number determines the height in px. | Integer or String | 'auto' |
mobileDropdown |
If your navigation hides and is used as a dropdown on small screens setting this to true hides the dropdown after a click. | Boolean | false |
mobileDropdownClassName |
Additionaly you can insert the mobile nav's classname here, when left empty the plugin searches for a <ul> in the same parent element. |
String | '' |
mobileBreakpoint |
The 'mobile' breakpoint (like the max-width of a media query). It's recommended that you check this if you use mobile dropdown support. | Integer | 1024 |
scrollSpy |
Set to true if you want to enable the scrollspy, it adds an active class to the nav items when you scroll past their sections. | Boolean | false |
activeParent |
Set to true if you want the parent of the anchor to have an active class instead of the anchor itself (only if ScrollSpy is enabled). | Boolean | false |
activeClassName |
Set the name of the active class when using ScrollSpy. | String | 'active' |
Specific scrollTime
The scrollTime option is for all <a> tags inside the element on which navScroll is called. If you want different scrollTimes for different anchors you have to include the data-attribute data-scrolltime. The value should be a number. The 'Section 3' URL in the demo is an example of this.
Callbacks
| Name | Description | Type |
|---|---|---|
onScrollStart |
Callback function, will be executed when the scrolling animation starts. | Function |
onScrollEnd |
Callback function, will be executed when the scrolling animations ends. | Function |
$('.nav').navScroll({
onScrollStart: function() {
// Execute code when the scrolling starts.
},

}
