javascript - Negative Positioning with JQuery scrollTolocalScroll - Stack Overflow

文章数量:1336644

I'm working on a project and using Ariel Flesler's jquery.scrollTo.js & jquery.localScroll.js ... I have local links that scroll to various divs on the page.

The trouble I have is that I have a fixed position navbar at the top of the page and ScrollTo is calculating the window position (correctly) without factoring that in. Below is the scrollTo.js file... can someone show me where and how I would insert code that would cause the Y-axis scroll position to be +[Y]px?

• That code is obfuscated. It's kinda difficult to reverse engineer. However, there is probably an option on the plugin that lets you set an initial offset. – Joel Commented Feb 15, 2010 at 20:21
• Actually, that code is just minified version of ScrollTo plugin. Their homepage provides a full version as well, just grab and edit it. – BalusC Commented Feb 15, 2010 at 20:28
• Minified... close enough to obfuscated. ;) Either way, why modify the source when the option is built in. – Joel Commented Feb 15, 2010 at 20:29

Look at http://demos.flesler./jquery/scrollTo/ . Specifically the offset option.

You can add using the offset with a hash, something like

$(...).scrollTo( '#myitem', speed, {offset: {top:20px, left:0} });
