text Development

The <text> component is used to display a piece of textual information. For details, see text.

Creating a <text> Component

Create a <text> component in the .hml file under pages/index.

<!-- xxx.hml -->
<div class="container" style="text-align: center;justify-content: center; align-items: center;">
  <text>Hello World</text>
</div>

/* xxx.css */
.container {
  width: 100%;
  height: 100%;
  flex-direction: column;
  align-items: center;
  justify-content: center;
  background-color: #F1F3F5;
}

Setting the Text Style and Attributes

• Adding a text style

  Set the color, font-size, allow-scale, word-spacing, and text-align attributes to add the color, size, zoom, text spacing, and vertical alignment of the text.

  <!-- xxx.hml -->
  <div class="container" style="background-color:#F1F3F5;flex-direction: column;justify-content: center; align-items: center;">   
    <text style="color: blueviolet; font-size: 40px; allow-scale:true"> 
      This is a passage
    </text>
    <text style="color: blueviolet; font-size: 40px; margin-top: 20px; allow-scale:true;word-spacing: 20px;text-align: center">
      This is a passage
    </text>
  </div> 
  

  /* xxx.css */
  .container {
    display: flex;
    width: 100%;
    height: 100%;
    flex-direction: column;
    align-items: center;
    justify-content: center;
    background-color: #F1F3F5;
  }
  

  

• Adding a text decoration

  Set the text-decoration attribute to add a decoration line to selected text. Set the text-decoration-color attribute to apply specific color to the decoration line. For values of text-decoration, see text styles.

  <!-- xxx.hml -->
  <div class="container" style="background-color:#F1F3F5;">
    <text style="text-decoration:underline">
      This is a passage
    </text>
    <text style="text-decoration:line-through;text-decoration-color: red">
      This is a passage
     </text>
  </div>
  

  /* xxx.css */
  .container {
    width: 100%;
    height: 100%;
    flex-direction: column;
    align-items: center;
    justify-content: center;
  }
  text{
    font-size: 50px;
  }
  

  

• Hiding text content

  Set the text-overflow attribute to ellipsis so that overflowed text is displayed as an ellipsis.

  <!-- xxx.hml -->
  <div class="container">
    <text class="text">
      This is a passage
    </text>
  </div>
  

  /* xxx.css */
  .container {
    width: 100%;
    height: 100%;
    flex-direction: column;
    align-items: center;
    background-color: #F1F3F5;
    justify-content: center; 
  }
  .text{
    width: 200px;
    max-lines: 1;
    text-overflow:ellipsis;
  }
  

  NOTE

  • text-overflow must be used together with max-lines.
  • max-lines indicates the maximum number of lines in the text.

  

• Setting the <span> child component

  <!-- xxx.hml -->
  <div class="container" style="justify-content: center; align-items: center;flex-direction: column;background-color: #F1F3F5;  width: 100%;height: 100%;">
    <text style="font-size: 45px;">
      This is a passage
    </text>
    <text style="font-size: 45px;">
      <span style="color: aqua;">This </span><span style="color: #F1F3F5;">      1       
      </span>   
      <span style="color: blue;"> is a </span>    <span style="color: #F1F3F5;">      1    </span>    
      <span style="color: red;">  passage </span>
    </text>
  </div>
  

  

  NOTE

  • When the <span> child component is used to form a text paragraph, incorrect <span> attribute settings (for example, setting of font-weight to 1000) will result in abnormal display of the text paragraph.

  • When the <span> child component is being used, do not include any text you want to show in the <text> component, as such text will not be displayed if you do so.

Example Scenario

Use the <text> component to display text content through data binding. Use the <span> child component to hide or display text content by setting the show attribute.

<!-- xxx.hml -->
<div class="container">
  <div style="align-items: center;justify-content: center;">
    <text class="title">
      {{ content }}
    </text>
    <switch checked="true" onchange="test"></switch>
  </div>
  <text class="span-container" style="color: #ff00ff;">
    <span show="{{isShow}}">  {{ content  }}  </span>
    <span style="color: white;">
        1
    </span>
    <span style="color: #f76160">Hide clip </span>
  </text>
</div>

/* xxx.css */
.container {
  width: 100%;
  height: 100%;
  align-items: center;
  flex-direction: column;
  justify-content: center;
  background-color: #F1F3F5;
}
.title {
  font-size: 26px;
  text-align:center;
  width: 200px;
  height: 200px;
}

// xxx.js
export default {   
  data: {    
    isShow:true,    
    content: 'Hello World'
  },   
  onInit(){    },  
  test(e) {    
    this.isShow = e.checked  
  }
}
