Hiding elements in HTML with React when data is null

Is there a way to hide elements using classes like "d-none" when the data is null in React?

 <span className="product__tag">{prod.tag1}</span>
 <span className="product__tag">{prod.tag2}</span>
 <span className="product__tag">{prod.tag3}</span>

Answer №1

If you want to hide empty spans using CSS, you can utilize the :empty selector:

span:empty{display:none;}

Be cautious of the specificity of the selector in case the display property of span is modified elsewhere.

Answer №2

If you want to experiment, consider using the code snippet below:

{product.tag1 && <span className="product__tag">{product.tag1}</span>}

Answer №3

Utilizing Inline Styles

An effective method to achieve this is by using inline styles. By checking if the data is null, you can set the display property to none accordingly.

const checkData = data == null ? "none" : "block"

...

<span style={{display: checkData}} className="product__tag">{prod.tag1}</span>
<span style={{display: checkData}} className="product__tag">{prod.tag2}</span>
<span style={{display: checkData}} className="product__tag">{prod.tag3}</span>

Modifying the Class

This approach mirrors the previous one. Instead of directly altering the style, you can modify the class and then adjust the style based on that class. This technique is likely more organized and suitable for larger projects.

const checkData = data == null ? "product__tag__hide" : "product__tag"
        
...
        
<span className={checkData}>{prod.tag1}</span>
<span className={checkData}>{prod.tag2}</span>
<span className={checkData}>{prod.tag3}</span>

... 
css

.product__tag__hide{
display: none;
}

Answer №4

Technique 1:-

 <span className="product__tag" style={{display: (prod.tag1 ? 'block':'none')}}>
   {prod.tag1}
 </span>
 

Approach 2:-

 {prod.tag1 && <span className="product__tag">{prod.tag1}</span>}

Strategy 3:-

{prod.tag1 ? <span className="product__tag">{prod.tag1}</span>: null}
