Question

在我的项目中，我正在从服务器获取html内容的json响应。

我使用react-native-render-html来呈现html。但是表内容没有显示。

有什么方法可以在react native中显示html表吗？那怎么可能呢？任何帮助都是非常可观的。请帮忙。我尝试了诸如react-native-htmlview之类的不同方法。似乎没有按预期工作，以下是我使用react-native-render-html呈现html内容的代码。

How it can be raised is through achieving more productivity and employment generation in the sectors that can create big changes is decisive element for the country’s transition. Here comes the role of industrial sector. The industrial sector is known for generating huge employment with minimum skill addition. Similarly, no other sector has higher level of tradability as the industrial sector (means a country can earn big income through exports). Graduating to an expanded services sector without undergoing industrialisation will be self-defeating and unsuitable to a big economy like India. Depending on services sector for exports will not reward as other countries like to protect their services sector from the inflow of India’s skilled persons. If India can increase the contribution of the industrial sector in GDP from the present 30 per cent to say 40-45 %, it implies that sizable income and employment are created in the sector.</p> <ol style="

我只粘贴了我的json响应的一小部分，只是为了显示html内容。下面的代码也只是我的渲染方式的一小部分，请帮助我找到解决方案。

<Content>
      {this.state.section.map(article =>

         <CardItem>

         <HTML  html={article.data.description} imagesMaxWidth={Dimensions.get('window').width} />
         </CardItem>
           )}
        </Content>

Answer 1

尝试使用以下代码段，基本上所有表标签都将替换为iframe。

let staticHtml = `<h1>This HTML snippet is now rendered with native components !</h1> <h2>Enjoy a webview-free and blazing fast application</h2> <img src="i.imgur.com/dHLmxfO.jpg?2" /> <em style="textAlign: center;">Look at how happy this native cat is</em> <h2>HTML Table</h2> <table> <tr> <th>Company</th> <th>Contact</th> <th>Country</th> </tr> <tr> <td>Alfreds Futterkiste</td> <td>Maria Anders</td> <td>Germany</td> </tr> <tr> <td>Centro comercial Moctezuma</td> <td>Francisco Chang</td> <td>Mexico</td> </tr></table> `;
  //
  let content = staticHtml;
  const tables = staticHtml.match(/(<table(?:.|\n)*?<\/table>)/g);
  
  tables.map((table) => {
    content = content.replace(table, `<iframe srcdoc="${table}"></iframe>`);
  });

console.log("content after including iframe =>", content)
