How to set the style attribute in react?

Setting style style in React

1. Set inline style:

1. Basic settings:

Use {}, pass in an object {padding: '2px 0 5px 20px', overflowY: 'auto'}

As shown below:

<div style={{padding: &#39;2px 0 5px 20px&#39;,overflowY: &#39;auto&#39;}}

2. Set percentage (relative data)

<div style={{width: &#39;calc(100% - 35px)&#39;,height: &#39;calc(100% - 15px)&#39;}}>

3. Set by function:

For example, write a function to calculate the height of the window:

//参数 adjustValue的作用是在window.innerHeight的基础上，减去多少高度，可以是负值，0，正值
function getWinHeight(adjustValue) {
    let winHeight;
    if (window.innerHeight) {
      winHeight = window.innerHeight;
    } else if ((document.body) && (document.body.clientHeight)) {
      winHeight = document.body.clientHeight;
    }
    return winHeight-adjustValue;
  }

Then use it in the style:

<div style={{width: &#39;calc(100% - 35px)&#39;,height: getWinHeight(200)}}>
    <div id="jsoneditor" className="jsoneditor-react-container"  />
</div>

2. Miscellaneous:

1. The table occupies the entire row:

Set the style of the table tag to style={{width: 'calc(100% - 10px)'}}

<table style={{width: &#39;calc(100% - 10px)&#39;}}>
  <tr>
    <td style={{width:&#39;50px&#39;}}>
      <div style={{paddingTop:"10px",marginLeft:&#39;10px&#39;}}>
        <Button
          id="returnButtonId"
          text=""
          icon={"ic_arrow_back"}
          onClick={doBack}
        />
      </div>
    </td>
    <td>
      <div style={{paddingTop:&#39;10px&#39;}}>Edit Parameter Files</div>
    </td>
    <td>
      <div style={{float:&#39;right&#39;, margin:&#39;0 10px 0 10px&#39;, paddingTop:&#39;10px&#39;}}>
        <Button
            id="`uploadButtonId`"
            text="UPLOAD"
            icon={"ic_arrow_upward"}
            onClick={onUploadClicked}
        />
      </div>
    </td>
  </tr>
</table>

2. Setting the height of the parent dc6dce4a544fdca2df29d5ac0ea9906b does not work:

If the height setting of the parent dc6dce4a544fdca2df29d5ac0ea9906b does not work, then the height of the child dc6dce4a544fdca2df29d5ac0ea9906b must also be set, which can be done with the parent < The height of ;div> remains the same.

As shown in the figure below: the height of parent and childdc6dce4a544fdca2df29d5ac0ea9906b is set to getWinHeight(180)

      <div style={{height: getWinHeight(180), border:&#39;2px&#39;}}>
          <SplitScreen
            id="parameterfiles-panel"
            left={
              <div style={{height: getWinHeight(180)}}>
              ..........
              </div>
            }
            right={
              <div style={{ whiteSpace: "nowrap"}}>
                  <div style={{padding: &#39;2px 0 5px 20px&#39;,overflowY: &#39;auto&#39;, width: &#39;calc(100% - 35px)&#39;,height: getWinHeight(180)}}>
                    <div id="jsoneditor" className="jsoneditor-react-container"  />
                  </div>
              </div>
            }
          />
        </div>

Writing so much for the time being, I will think of it later Otherwise, write again.
