Considering the presence of Fragments in React and the lack of a specific solution in the official Vuejs GitHub thread, what alternative methods could be used in Vuejs? This information may be beneficial for developers transitioning from a React background who are accustomed to render function styles and JSX.
If you're working on a component and already have a root div with multiple nodes from sub-render functions, it's simple to handle.
In React, we often divide render functions and the same approach can be taken here as well.
Here is a possible solution:
Below is the code snippet:
render(h) {
return (
<div>
{this.isConfirm ? this.renderF1(h) : this.renderF2(h)}
</div>
);
},
methods: {
//eslint-disable-next-line
renderF1: function(h){
return [
<div></div>,
<div class='anotherDiv'></div>
]
},
//eslint-disable-next-line
renderF2: function(h){
return [
<span></span>,
<div class='secondDiv'></div>
]
}
}
An Explanation:
The first step involves returning multiple root node elements in an array like this:
return [node, node];
Then, pass the h function as an argument to the smaller render functions from your main render function to avoid Vue CLI errors related to function h.
Once these adjustments are made, the code should run without issues.
Additional Note: If you are using eslint, consider adding this line at the top of each render function to prevent compilation errors:
//eslint-disable-next-line
Also, if you are new to JSX in Vuejs, you can utilize the official Babel plugin package for assistance.
When dealing with component hierarchies, ensure that you structure them in such a way that avoids errors when using arrays as the root element.
For instance, attempting something similar to:
render(h) {
return [
<div>
{this.isConfirm ? this.renderF1(h) : this.renderF2(h)}
</div>
];
},
This will prompt an error message like:
