Usage

import React, { Component } from 'react';
import ReactTextMoreLess from 'react-text-more-less';

class Demo extends Component {
  state = {
    collapsed: true,
  };

  render() {
    const { collapsed } = this.state;
    return (
      <ReactTextMoreLess
        collapsed={collapsed}
        text="1926年1—6月，他一连发表了四篇论文，题目都是《量子化就是本征值问题》，系统地阐明了波动力学理论。在此以前，德国物理学家W.K.海森堡、M.玻恩和E.P.约旦于1925年7—9月通过另一途径建立了矩阵力学。1926年3月，薛定谔发现波动力学和矩阵力学在数学上是等价的，是量子力学的两种形式，可以通过数学变换,从一个理论转到另一个理论。薛定谔起初试图把波函数解释为三维空间中的振动，把振幅解释为电荷密度，把粒子解释为波包。但他无法解决“波包扩散”的困难。最后物理学界普遍接受了玻恩提出的波函数的几率解释。"
        lessHeight={72}
        showMoreText="... 展示更多"
        showMoreElement={
          <span>
            ... <span className="show-more-text">展示更多</span>
          </span>
        }
        showLessElement={<span className="show-more-text">收起</span>}
        onClick={() => {
          this.setState({ collapsed: !collapsed });
        }}
      />
    );
  }
}

If you like to prevent collapse on user select, add this before setting collapsed.

const selection = window.getSelection();
if (!selection.toString()) {
  /* Set `collapsed` prop */
}

Props

name	type	isRequired	default	description
text	string	✔	N/A	text in the container
lessHeight	number	✔	N/A	container collapsed height
collapsed	bool	✖	true	is the container collapsed according to the lessHeight
className	string	✖	undefined	className of the container
showMoreText	string	✖	...	the ellipse text to show more
showMoreElement	element	✖	undefined	the element to show when container collapsed
showLessElement	element	✖	undefined	the element to show when container expanded
onClick	func	✖	() => {}	container click handler
rootProps	object	✖	{}	root container props, could be any props a div accepts

If showMoreElement supplied, showMoreText will be replaced, this props is useful when you want to custom showMoreText style or to use a more complex dom structure to display showMoreText.
