Conditional Rendering in LWCToday we learn about the lwc:if, lwc:elseif, and lwc:else conditional directives that are introduced in the Spring-23 release and how they replace the if: true and if: false directives.
- Conditional directives in LWC are widely used in salesforce lightning app development in USA, which allows you to conditionally render or hide an element based on the value of an expression. The three main conditional directives in LWC are lwc: if, lwc: elseif, and lwc: else
- The lwc:else directive is used to render elements if none of the conditions specified in the lwc:if and lwc:elseif directives are true.
- The syntax for the lwc:if and lwc:else directive is as follows:
lwc:elseif directive: –
- The lwc:elseif directive is used to render elements if the condition specified in the lwc:if the directive is false, and a different condition is true.
- The syntax for the lwc:elseif directive is as follows:
- You can use template variables in the expression for lwc:if. A template variable is a placeholder for a value that you can reference in your component’s HTML template.
- Be mindful of the order of elements: The order of elements in the HTML template matters when using lwc:if and lwc:else. Make sure to place the lwc:else directive after all of the lwc:if directives to avoid unexpected results.
