I have a React app like this:
index.html:
<div class="asset_infos" data-keyID="msg_1"></div>
<div class="asset_infos" data-keyID="msg_2"></div>
...
<div class="asset_infos" data-keyID="msg_n"></div>
and index.js:
var Msg = props => (
<div>It is { props.keyID }</div>
);
document.querySelectorAll('.asset_infos')
.forEach(domContainer => {
ReactDOM.render(<Msg {...(domContainer.dataset)} />,
domContainer
);
});
I want the data from the data-keyID attribute of each < div > to be transferred to the Msg variable and to be diplayedd, but it doesn't. Do you know how to do so?
You can pass the props like below. See the demo https://jsfiddle.net/uveh5d48/1/
document.querySelectorAll('.asset_infos')
.forEach(domContainer => {
ReactDOM.render(<Msg keyID = {domContainer.dataset.keyid} />,
domContainer
);
});
