Optimize Toolset

I’ve always been into building performant and accessible sites, but lately I’ve been taking it extremely seriously. So much so that I’ve been building a tool to help me optimize and monitor the sites that I build to make sure that I’m making an attempt to offer the best experience to those who visit them. If you’re into performant, accessible and SEO friendly sites, you might like it too! You can check it out at Optimize Toolset.

About

Hi, 👋, I’m Ryan Hefner  and I built this site for me, and you! The goal of this site was to provide an easy way for me to check the stats on my npm packages, both for prioritizing issues and updates, and to give me a little kick in the pants to keep up on stuff.

As I was building it, I realized that I was actually using the tool to build the tool, and figured I might as well put this out there and hopefully others will find it to be a fast and useful way to search and browse npm packages as I have.

If you’re interested in other things I’m working on, follow me on Twitter or check out the open source projects I’ve been publishing on GitHub.

I am also working on a Twitter bot for this site to tweet the most popular, newest, random packages from npm. Please follow that account now and it will start sending out packages soon–ish.

Open Software & Tools

This site wouldn’t be possible without the immense generosity and tireless efforts from the people who make contributions to the world and share their work via open source initiatives. Thank you 🙏

Readme

drag

针对网页中出现的拖曳插件,边界判断,fixed定位拖动.基于jQuery 或者zepto.包括针对父级容器内的拖动处理

npm 安装

npm install --save jq-drag

Demo

http://tianxiangbing.github.io/drag/index.html

//默认无限制拖动
var drag = new Drag();
drag.init({ target: '#dragdefault' });
//在body内的拖动
var dragbody = new Drag();
dragbody.init({ target: '#dragbody', boundary: true });
//绝对定位相对于window的拖动
var dragfix = new Drag();
dragfix.init({ target: '#dragfix', boundary: true });
//拖动手柄
var dragheader = new Drag();
dragheader.init({ target: '#dragheader',handle:'.handle'});
//在父级容器内的拖动
var dragparent = new Drag();
dragparent.init({ target: '#dragparent', boundary: true,parent:'.parent' });
//在父级容器内的拖动,父级有定位position
var dragparent2 = new Drag();
dragparent2.init({ target: '#dragparent2', boundary: true,parent:'.parent2' });

或者使用jQuery插件的方式调用

$('.drag').Drag({boundary:true});//options一致

API

init:function()

在new 的方法调用时的初始化方法,使用`$.fn`的插件方式不需要

target:string|dom

需要移动的元素

boundary:bool

是否有边界的限制,默认以body为边界,可以指定parent

parent:string|dom

父级容器作为边界,这有两种情况,父级无定位的和有定位的

startCallack:(this.target, this.pos, this.position)

开始时的回调

stopCallack:(this.target, this.pos);

结束的回调,第二个参数是当前位置

moveCallack:(this.target, x, y);

移动时的回调,x、y对应移动到的left和top
