I've made a project in React and HTML5. Previously, to call my render function I had put my render into a global function like this:
window.shareRenderResetResult = function () {
ReactDOM.render(
<div> hello </div>,
document.getElementById('salut')
);
};
and I called it in my html page like this:
<script>
shareRenderResetResult();
</script>
Today, for an another project, I have do the same things but I now get a warning in my console:
Uncaught ReferenceError: shareRenderResetResult is not defined
at (index):207 (anonymous) # (index):207
I don't know what to do. Ideas?
my html page :
<!DOCTYPE html>

I have an index.html file that is getting data from app.py (pulling from MongoDB) using render_template and I am attempting to read the data loaded in the index.html into my logic.js so I can create a leaflet map. However, it seems that the data is not loading in my logic.js. Any thoughts?
Here is my index.html:

Help fix the error! Thank!
firebase-messaging-sw.js is service worker JavaScript file.
So you should not load JavaScript file using <script src="firebase-messaging-sw.js"></script>.
Remove <script src="firebase-messaging-sw.js"></script> and try the following code.
<script>
if ('serviceWorker' in navigator) {
window.addEventListener('load', () => {
navigator.serviceWorker.register('/firebase-messaging-sw.js');
});
}
</script>
See https://developers.google.com/web/fundamentals/primers/service-workers/#register_a_service_worker
I have this template as my sinatra layout.erb

and this small javascript call
console.log("running")
$('#datepicker').datepicker()
the server gets a 200 call to the js file but nothing will print to the console or execute.
Always use <script></script>.
<script src="..." /> is not a valid tag. When the HTML is parsed, it thinks that <script src="/static/js/jobs/new.js" /> is in the body of the <script src="/static/js/bootstrap.min.js"/> tag like this:
...
<script src="/static/js/bootstrap.min.js">
<script src="/static/js/jobs/new.js">
...
From MDN <script> documentation:
Tag omission
None, both the starting and ending tag are mandatory.
I am using jquery mobile
I have 3 pages and after some clicks between the pages the css are not rendered
LoadCss.js
$(document).on("pageinit",function(event) {
$("#categoriesPage").on('pageshow', function () {
$('head').append('<link rel="stylesheet" type="text/css" href="scripts/rtl.jquery.mobile-1.4.0.css">');
$('head').append('<link rel="stylesheet" type="text/css" href="styles/myCss.css">');
});
$("#wordPage").on('pageshow', function () {
$('head').append('<link rel="stylesheet" type="text/css" href="scripts/rtl.jquery.mobile-1.4.0.css">');
$('head').append('<link rel="stylesheet" type="text/css" href="styles/myCss">');
});
$("#searchPage").on('pageshow', function () {
$('head').append('<link rel="stylesheet" type="text/css" href="scripts/rtl.jquery.mobile-1.4.0.css">');
$('head').append('<link rel="stylesheet" type="text/css" href="myCss">');
});
});

I tried also to put the CSS in the header and not on on event but it still didn't work
<link rel="stylesheet" href="scripts/rtl.jquery.mobile-1.4.0.css"/>
<link rel="stylesheet" href="styles/jplayer.pink.flag.min.css" rel="stylesheet">
Please try this method below, using the attribute method. note the order they are applied.
This will give better compatibility for all browsers too (IE has issues):
To test, don't put your JQuery code in the external LoadCSS.js file - put it into the HTML file. It should work every time. When loading from an external JS file, some events do not always trigger when you expect due to the browser caching the file.
As #nishi says, remember to remove the old CSS before adding the new ones.
$('<link>')
.appendTo('head')
.attr({type : 'text/css', rel : 'stylesheet'})
.attr('href', '/styles/myfile.css');
I am loading all of the below libraries and files, but for some reasons only the CSS is executing and none of the external js files. The scripts.js file holds all of my jQuery and it seems to be formatted properly. I'm not sure why the CSS would execute, but not the jQuery.
In chrome dev tools, everything below is loaded.
<head>
<!DOCTYPE html>
<meta charset=utf-8 />
<link rel="stylesheet" href="{{ url_for('static', filename='css/main.css') }}">
<link rel="stylesheet" href="{{ url_for('static', filename='css/spectrum.css') }}">
<link rel="stylesheet" type="text/css" href="http://fonts.googleapis.com/css?family=Open+Sans">
<script src="http://code.jquery.com/jquery-1.10.1.min.js"></script>
<script src="http://code.jquery.com/ui/1.10.3/jquery-ui.js"></script>
<script type="text/javascript" src="{{ url_for('static', filename='scripts/spectrum.js') }}"></script>
<script type="text/javascript" src="{{ url_for('static', filename='scripts/scripts.js') }}"></script>
</head>
This is a portion of the scripts.js file:
$("span.output").draggable({
stop: function(event, ui) {}
});
$('input[type=file]').change(
function() {
$('#submitbutton').click();
});
$("#text_submit").submit(
function(event) {
$("#text1").html($("#1").val());
$("#text2").html($("#2").val());
$("#text3").html($("#3").val());
$("#text4").html($("#4").val());
$("#text5").html($("#5").val());
$("#text6").html($("#6").val());
$("#text7").html($("#7").val());
$("#text8").html($("#8").val());
$("#text9").html($("#9").val());
$("#text10").html($("#10").val());
$("#slider1").show();
$("#slider2").show();
$("#slider3").show();
$("#slider4").show();
$("#slider6").show();
$("#slider7").show();
$("#slider8").show();
$("#slider9").show();
event.preventDefault();
});
You need to put your code inside script.js in JQuery's Dom Ready function, like this;
$(document).ready(function(){
// Your code here
});
For more info, http://api.jquery.com/ready/
Try the below, not declaring type="text/javascript" in your jquery loading way might also be an issue.
<head>
<!DOCTYPE html>
<meta charset=utf-8 />
<link rel="stylesheet" href="{{ url_for('static', filename='css/main.css') }}">
<link rel="stylesheet" href="{{ url_for('static', filename='css/spectrum.css') }}">
<link rel="stylesheet" type="text/css" href="http://fonts.googleapis.com/css?family=Open+Sans">
<script src="http://code.jquery.com/jquery-1.10.1.min.js" type="text/javascript"></script>
<script src="http://code.jquery.com/ui/1.10.3/jquery-ui.js" type="text/javascript"></script>
<script type="text/javascript" src="scripts/spectrum.js"></script>
<script type="text/javascript" src="scripts/scripts.js"></script>
