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 🙏

watermark-component

watermark-com是一个通用的水印库,项目运用rollup构建,输出iife、cjs、esm三个压缩文件,分别对应了三种使用方式,能够适用于原生js,react、Vue、angular、jq等主流框架。支持监听浏览器resize事件和mutationObserve对象监听DOM变化并做相应的调整。

一、使用方法

1、本地引入js文件

第一步:在页面中引入水印文件

<script type="text/javascript" src=""></script>

第二步:在确保页面DOM加载完毕之后,调用watermark方法

watermarkObj.watermark({ text: "这是测试水印" })

2、npm包引入

第一步:npm获取水印包

npm install watermark-component --save
# yarn add watermark-component

第二步:引入水印模块

import { watermark } from 'watermark-com'
// const watermark = require('watermark-com')

第三步:在确保页面DOM加载完毕之后,调用watermark方法

watermark({ text: "这是测试水印" })

注意:当需要加水印的内容部分有滚动的情况,我们建议在需要加载水印的容器下加一个:

<div id='watermarkId'>content</div>

把需要加水印的内容部分包裹起来,以这个div当做水印元素的父节点,content为需要加水印的内容节点

二、配置项

{
  id: 'wm_div_id', // 水印总体的id
  text: '测试水印', // 水印的内容
  transparency: 0.15, // 水印透明度
  fontColor: '#727071', // 水印字体颜色
  fontWeight: 'normal', // 水印字体粗细
  fontSize: 16, // 水印字体大小,以px为单位
  parentLeft: 0, // 水印整体左边距离
  parentTop: 0, // 水印整体顶边距离
  parentRight: 0, // 水印整体右边距离
  parentBottom: 0, // 水印整体顶边距离
  singleWidth: 200, // 单个水印宽度
  singleHeight: 200, // 单个水印长度
  slope: -15, // 水印倾斜度数
  parentSelector: null, // 水印插件挂载的父元素选取器,不输入则默认挂在body上
}

注意:

  • 若watermark()没有传任何配置则使用的是以上的默认配置,常用的配置项是text,若对水印的样式有要求的可自行传入相关的配置项。
  • parentSelector不传则默认挂在body上。
  • 若挂载在body下,水印不会随着内容的滚动而滚动,若挂载到滚动的内容上则可以随着内容的滚动而滚动,可根据需求自行选择。
  • 加水印后有可能会影响到内容的绝对定位,若有影响需调整页面样式。

三、浏览器支持情况

Chrome、FireFox、Safari、IE10及以上浏览器支持全部功能

IE10及以下不支持水印被用户手动调用开发者工具删除水印dom的情况
