Reactjs-pull-refresh NPM

reactjs-pull-refresh

This is a react component for pull down refresh.

Install

npm install reactjs-pull-refresh --save

Example

npm install
gulp example

http://localhost:9090

Online Example

http://reactjs-ui.github.io/reactjs-pull-refresh/

Build Example

第一次需要先执行前两步操作，再执行第三步。以后修改例子后，只需要执行第三步即可

创建 gh-pages 分支，在执行 git subtree add 命令之前，需确保 gh-pages 分支下至少存在一个文件

git branch gh-pages
git checkout gh-pages
rm -rf *     //隐藏文件需要单独删除，结合命令 ls -a
git add -A
git commit -m "clear gh-page"
git push --set-upstream origin gh-pages
vim README.md
//输入一些内容
git add README.md
git commit -m "README.md"
git push
git checkout master

把分支 gh-pages 添加到本地 subtree 中，执行该命令前，请确保 examples-dist 文件夹不存在

git subtree add --prefix=examples-dist origin gh-pages --squash

生成在线 examples

gulp example:build
git add -A examples-dist
git commit -m "Update online examples"
git subtree push --prefix=examples-dist origin gh-pages --squash
git push

Usage

import React, {Component, PropTypes} from 'react';
import {render} from 'react-dom';
import injectTapEventPlugin from 'react-tap-event-plugin';
import PullRefresh from '../src/scripts/index';
import './sass/example.scss';

// 初始化 tapEvent 事件, 移动端
injectTapEventPlugin();

  };

  render() {
    let contents = [];
    const {items, hasMore} = this.state;

    for (let i = items; i > 0; i--) {
      if (i < 10) {
        contents.push(<li key={i}><a href="http://www.sina.com">这里放置真实显示的DOM内容</a> {i}</li>);
      } else {
        contents.push(<li key={i} onTouchTap={this.handleTouchTap}>这里放置真实显示的DOM内容 {i}</li>);
      }
    }

    const props = {
      maxAmplitude: 80,
      debounceTime: 30,
      throttleTime: 100,
      deceleration: 0.001,
      refreshCallback: this.refreshCallback,
      loadMoreCallback: this.loadMoreCallback,
      hasMore
    };

    return (
