使用reactjs渲染原始html

所以这是唯一的方式来渲染原始html与reactjs?

// http://facebook.github.io/react/docs/tutorial.html
// tutorial7.js
var converter = new Showdown.converter();
var Comment = React.createClass({
  render: function() {
    var rawMarkup = converter.makeHtml(this.props.children.toString());
    return (
      <div className="comment">
        <h2 className="commentAuthor">
          {this.props.author}
        </h2>
        <span dangerouslySetInnerHTML={{__html: rawMarkup}} />
      </div>
    );
  }
});

我知道有一些很酷的方法可以用JSX标记东西，但我主要感兴趣的是能够呈现原始html(包括所有的类、内联样式等)。像这样复杂的事情:

<!-- http://getbootstrap.com/components/#dropdowns-example -->
<div class="dropdown">
  <button class="btn btn-default dropdown-toggle" type="button" id="dropdownMenu1" data-toggle="dropdown" aria-expanded="true">
    Dropdown
    <span class="caret"></span>
  </button>
  <ul class="dropdown-menu" role="menu" aria-labelledby="dropdownMenu1">
    <li role="presentation"><a role="menuitem" tabindex="-1" href="#">Action</a></li>
    <li role="presentation"><a role="menuitem" tabindex="-1" href="#">Another action</a></li>
    <li role="presentation"><a role="menuitem" tabindex="-1" href="#">Something else here</a></li>
    <li role="presentation"><a role="menuitem" tabindex="-1" href="#">Separated link</a></li>
  </ul>
</div>

我不想在JSX中重写所有这些内容。

也许我想错了。请纠正我。

这对我来说很管用:

    render()
    {
        var buff = '';
        for(var k=0; k<10; k++)
        {
            buff += "<span> " + k + " </span>";
        }

        return (
            <div className='pagger'>               
                  <div className='pleft'>
                     <div dangerouslySetInnerHTML={{__html: buff }} />
                  </div>
                  <div className='pright'>
                         <div className='records'>10</div>
                         <div className='records'>50</div>
                         <div className='records records_selected'>100</div>
                         <div className='records'>1000</div>
                     </div>
            </div>
        )
    }

你可以利用html-to-react npm模块。

注意:我是这个模块的作者，几个小时前刚刚发布了它。请随时报告任何bug或可用性问题。

下面是之前发布的一个不那么武断的RawHTML函数版本。它让你:

配置标签可选地将换行符替换为<br /> 传递额外的道具，RawHTML将传递给创建的元素提供一个空字符串(RawHTML></RawHTML>)

下面是这个组件:

const RawHTML = ({ children, tag = 'div', nl2br = true, ...rest }) =>
    React.createElement(tag, {
        dangerouslySetInnerHTML: {
            __html: nl2br
                ? children && children.replace(/\n/g, '<br />')
                : children,
        },
        ...rest,
    });
RawHTML.propTypes = {
    children: PropTypes.string,
    nl2br: PropTypes.bool,
    tag: PropTypes.string,
};

用法:

<RawHTML>{'First &middot; Second'}</RawHTML>
<RawHTML tag="h2">{'First &middot; Second'}</RawHTML>
<RawHTML tag="h2" className="test">{'First &middot; Second'}</RawHTML>
<RawHTML>{'first line\nsecond line'}</RawHTML>
<RawHTML nl2br={false}>{'first line\nsecond line'}</RawHTML>
<RawHTML></RawHTML>

输出:

<div>First · Second</div>
<h2>First · Second</h2>
<h2 class="test">First · Second</h2>
<div>first line<br>second line</div>
<div>first line
second line</div>
<div></div>

它会打破:

<RawHTML><h1>First &middot; Second</h1></RawHTML>

        for(var k=0; k<10; k++)
        {

        }

        return (
            <div className='pagger'>               
                  <div className='pleft'>
                     <div dangerouslySetInnerHTML={{__html: buff }} />
                  </div>
                  <div className='pright'>
                         <div className='records'>10</div>
                         <div className='records'>50</div>
                         <div className='records records_selected'>100</div>
                         <div className='records'>1000</div>
                     </div>
            </div>
        )
    }

我使用了这个名为Parser的库。它满足了我的需要。

import React, { Component } from 'react';    
import Parser from 'html-react-parser';

class MyComponent extends Component {
  render() {
    <div>{Parser(this.state.message)}</div>
  }
};

我曾在一些快速且不太规范的情况下使用过这个短语:

// react render method:

render() {
    return (
      <div>
        { this.props.textOrHtml.indexOf('</') !== -1
            ? (
                <div dangerouslySetInnerHTML={{__html: this.props.textOrHtml.replace(/(<? *script)/gi, 'illegalscript')}} >
                </div>
              )
            : this.props.textOrHtml
          }

      </div>
      )
  }
