ReactJS 如何在字符串中呈现 HTML 对象跨度元素

Question

How can I convert an HTML object containing a span element within a string into something that Reactjs can actually render as HTML?

To clarify, here's what I have:

let myObject = "apple tree"

I wrote a function that wraps the word apple in a span tag (html object)

<span style="color: red;">apple</span>tree

my website is displaying:

[object Object] tree

BUT it should be displaying

apple tree

where "apple" is colored red because it is wrapped in a span

I'm passing the string into my component like this:

return (<div>{myObject}</div>)

Not sure how to render this object as actual HTML element, and not sure if I doing dangerouslySetInnerHTML is the best and only option here too

Answer 1

How about this?

{<span style="color: red;">{'apple'}</span>tree}

Lemme know if it works.

Answer 2

If you want to render an HTML object it's just

let myObject=<span style="color: red;">apple</span>;
return (<div>{myObject} tree</div>);

if you are doing something like this return (<div>{this.getRedApple()} tree</div>); then in your getRedApple() function you should just return the variable like so:

let myObject=<span style="color: red;">apple</span>;
return (myObject);

Don't have it like this: return ({myObject})

Create component for it

class Apple extends Component {
          render() {
            return <span color={this.props.style.color} >{this.props.strApple}</span>tree;
          }
        }

use that component;

  const style = { color: 'red' };
  const element = <Apple strApple="apple tree" style="style "/>; 

And render it

ReactDOM.render(
  element,
  document.getElementById('root')
);

This Question is already answered here. Insert value of object into span tag

Referring to answer of Nitin Dhomse, you can do something like this:

let myObject = "apple tree";
<span id="span" style="color: red"></span>
$("#span").text(myObject); 

This will give you the required output.
