just do a variable forwarding. The script section sets these variables under window, and the external js directly accesses the variables
in the rendered html text by setting some variables in the script tag, but it will pollute the global variables. You can add a namespace
are you talking about ejs templates?
<% if (gameState) { %>
<h2>I have a game state!</h2>
<script>
var clientGameState = <%= gameState %>
</script>
<% } %>https://stackoverflow.com/que.
-at present, I can access the data from the background directly in the html template
directly in the script tag (without <% > package)
< script >
var articleData= <%-JSON.stringify (articleData)% >;
console.log (articleData.title)
< / script >
my article is a json object
so that it can be accessed, but it is not possible to write it in the imported external js file. It is always possible not to report the wrong use for the time being.
you can do two interfaces on the back end, one using res.render () to send html, to the browser and the other using res.json ({data:data}) to send json data to the browser.
