+# electron-find
+
+English | [简体中文](./README.zh-CN.md)
+
+## Introduction
+Find all matches for the text in electron app
+
+## Features
+- depend on the API of electron's findInPage
+- support user config UI of find interface

+
+## Demo
+
+### Default UI
+![demo](./find.gif)
+
+### Custom UI
+![demo](./find2.png)
+
+## Install
+``` 
+$   npm install electron-find --save
+```
+
+## Usage
+```
+# import module
+import { remote, ipcRenderer } from 'electron'
+import { FindInPage } from 'electron-find'
+
+# create instance of FindInPage with default config
+let findInPage = new FindInPage(remote.getCurrentWebContents())
+findInPage.openFindWindow()
+
+# use preload option, the find interface will be loaded when create instance
+let findInPage = new FindInPage(remote.getCurrentWebContents(), {
+  preload: true
+})
+findInPage.openFindWindow()
+
+# config parentElement of find interface, default is document.body
+let findInPage = new FindInPage(remote.getCurrentWebContents(), {
+  parentElement: document.querySelector('#id')
+})
+findInPage.openFindWindow()
+
+# config duration of find interface moving, default is 300 (ms)
+let findInPage = new FindInPage(remote.getCurrentWebContents(), {
+  duration: 200
+})
+findInPage.openFindWindow()
+
+# config offset relative to parentElement
+let findInPage = new FindInPage(remote.getCurrentWebContents(), {
+  offsetTop: 20,
+  offsetRight: 30
+})
+findInPage.openFindWindow()

+```
+
+## 使用
+```
+# 引入模块

+   - ` offsetTop ` Number - 指定查找窗口相对于父级定位元素顶部偏移量。 默认为 `5`。
+   - ` offsetRight ` Number - 指定查找窗口相对于父级定位元素右边偏移量。 默认为 `5`。
+   - ` boxBgColor ` String - 配置查找窗口背景色。 默认为 `"#ffffff"`。
+   - ` boxShadowColor ` String - 配置查找窗口阴影色。 默认为 `"#909399"`。
+   - ` inputColor ` String - 配置输入框文本颜色。 默认为 "#606266"。
+   - ` inputBgColor ` String - 配置输入框背景颜色。 默认为 `"#f0f0f0"`。
+   - ` inputFocusColor ` String - 配置输入框聚焦时的边框颜色。 默认为 `"#c5ade0"`。
+   - ` textColor ` String - 配置查找窗口中文本颜色。 默认为 `"#606266"`。
+   - ` textHoverBgColor ` String - 配置鼠标悬停文本时的背景色。 默认为 `"#eaeaea"`。
+   - ` caseSelectedColor ` String - 配置区分大小写选项选中时的边框颜色。 默认为 `"#c5ade0"`。
+
+ ### Instance Methods
+ 使用new FindInPage 创建的实例具有以下方法:      
+ &nbsp;  
+  ` findInPage.openFindWindow() `  
+ 当查找窗口关闭时，打开窗口。 当查找窗口已经打开时，聚焦输入框。  
+ &nbsp;   
+  ` findInPage.closeFindWindow() `  
+ 关闭窗口。    
+ &nbsp;   
+  ` findInPage.destroy() `  
+ 关闭窗口，清除对象的引用，释放内存。

+      <h3>关于 Electron</h3>
+      <p>
+        Electron是由Github开发，用HTML，CSS和JavaScript来构建跨平台桌面应用程序的一个开源库。
+      </p> 
+      <p>
+        Electron通过将Chromium和Node.js合并到同一个运行时环境中，并将其打包为Mac，Windows和Linux系统下的应用来实现这一目的。
+      </p>
+      <p>
+        Electron于2013年作为构建Github上可编程的文本编辑器Atom的框架而被开发出来。这两个项目在2014春季开源。
+      </p>
+      <p>
+        目前它已成为开源开发者、初创企业和老牌公司常用的开发工具。
+      </p>
+
+      <h3>长期支持</h3>
+      <p>
+        当前并不存在对Electron旧版本的长期支持
+      </p>
+      <p>
+        如果现在你使用的Electron版本跑得不错，你就可以一直使用这个版本。 
+      </p>
+      <p>
+        如果你想使用新发布的特性，那就升级到更新的版本。 
+      </p>
+      <p>
+        版本v1.0.0发布了重大的更新。 如果你现在没有在用这个版本，你应该了解更多关于v1.0.0的改变。 
+      </p>
+
+      <h3>核心理念</h3>
+      <p>
+        为了保持Electron的小巧 (文件体积) 和可持续性开发 (以防依赖库和API的泛滥) ，Electron限制了所使用的核心项目的数量。
+      </p>
+      <p>
+        比如Electron只用了Chromium的渲染库而不是其全部组件。 
+      </p>
+      <p>
+        这使得升级Chromium更加容易，但也意味着Electron缺少了Google Chrome里的一些浏览器相关的特性
+      </p>
+      <p>
+        添加到Electron的新功能应该主要是原生 API。 如果可以的话，一个功能应该尽可能的成为一个Node.js模块。
+      </p>
