Menu
I'm new to web programming, I was trying a very simple example in order understand how it works.
html file
<html>
<head>
<meta charset="ISO-8859-1">
<script type="text/javascript" src="/static/js/AddButton.js"></script>
<script type="text/javascript" src="/static/js/SendRequest.js"></script>
<title>{{title}}</title>
</head>
<body>
<button type="button" onclick="AddForm()"> + </button>
<div id = "newFormHere"></div>
<form action="javascript: SendFetchRequest()" id ="Form2">
Ticker2:
<input type="text" id="Ticker2" value="GOOG">
<input type="submit" value="Submit">
<div id = "FetchRequestOutput"></div>
</form>
</body>
</html>
I have one form (Form2) which sends a request to the server, and a button which adds more forms to the page.
SendRequest.js (exporting functions)
export {SendFetchRequest}
function SendFetchRequest()
{
var Ticker = document.getElementById("Ticker2");
fetch("action_page" + "?Ticker=" + Ticker.value).then(function(response){
response.text().then(function(data){
document.getElementById("FetchRequestOutput").innerHTML = data
})
})
}
Here I define the function I wish to attach to the buttons (I need to include it into the AddButton.js and in the html file)
AddButton.js (importing functions)
import { SendFetchRequest } from '/static/js/SendRequest.js';
function AddForm()
{
var myform = document.createElement("FORM");
myform.setAttribute("id", Math.random());
myform.setAttribute("type", "form");
myform.action = "javascript: SendFetchRequest()";
myinput = document.createElement("INPUT");
myinput.setAttribute("type", "text");
myinput.setAttribute("value", "SomeDefaultValue");
mysubmit = document.createElement("INPUT");
mysubmit,setAttribute("type", "submit");
mysubmit.setAttribute("value", "Submit")
myform.appendChild(myinput)
myform.appendChild(mysubmit)
document.getElementById("newFormHere").appendChild(myform)
};
Here the code to add new buttons dynamically.
I am testing this code with flask + Firefox 64. The error I'm getting is the following one.
SyntaxError: import declarations may only appear at top level of a module AddButton.js:6
SyntaxError: export declarations may only appear at top level of a module SendRequest.js:6.js:6
I have followed the first example on this page How do I include a JavaScript file in another JavaScript file?
If a try using "modules"
Loading failed for the module with source “http://127.0.0.1:5000/static/js/AddButton.mjs”.
Loading failed for the module with source “http://127.0.0.1:5000/static/js/SendRequest.mjs”.
the client can't even load the scripts.

type="text/javascript" should be type="module"
