I'm trying to load a .txt file into my simple html page. I'm very noobish and all the code i got is stolen from stackoverflow.
The text file is in the same folder as the html file and contains some text that I'd like to have shown in a div and not just loaded in at the start but dynamically updated (in a 1 sec interval).
The Page that results from the code is just empty.
I am using Chrome 73.
I only use the html file and the txt file. No other files are in the folder.
<html>
<head>
<script type="text/javascript">
setInterval(read,1000);
function read(){
jQuery.get('file.txt',function(data){$('#container').html(data);});
}
read();
</script>
</head>
<body>
<div id="container"></div>
</body>
</html>
I don't know what's wrong with this code. Am I missing libraries? If you came up with a completely new code that would be appreciated as well.
Yes, you are missing the jQuery library. Try it like this and let me know:
<html>
<head>
<script src="https://cdnjs.cloudflare.com/ajax/libs/jquery/2.2.4/jquery.min.js"></script>
<script type="text/javascript">
function read(){
jQuery.get('file.txt',function(data){$('#container').html(data);});
setTimeout(function(){read() },1000);
}
read();
</script>
</head>
<body>
<div id="container"></div>
</body>
</html>

See note in italics at very bottom of this article
what about a simple jQuery Load ?
$("#container").load("file.txt");

I've looked for some time on the internet to get the right awnser for my problem and asked some colleagues... I'm still at the same problem.
As follows:
(I'm new at using JS and jQuery)
I wanna load my own JS into my HTML (written in PHP).
<script src="standaard.js"></script>
and
<script src="test.js"></script>
standaard.js contains all of this: https://code.jquery.com/jquery-3.2.1.min.js
test.js
$(document).ready(function(){
$("button").click(function(){
$("p").fadeOut("slow");
});
});
and the <button> it refers to is in a PHP file:
<button id="button"> CLICK HERE!</button>
Now when I just load standaard.js and copy the contents of test.js in the PHP file between <script></script>, it works just as it should.
But when I load it from different files, it doesn't and when I inspect the page in Firefox console it gives me this:
SyntaxError: expected expression, got '}'
[More Info]
test.js:4:10
I hope someone could help me with this and that I didn't make a newbie mistake :)
Note: I suspect that it has something to do with time that both scripts need to load and that test.js goes first... but then again, I don't get the error that pops up.
EDIT:
Here is the trimmed PHP file:
<?php
echo '<!doctype html>
<html>
<head>
<title>Opdracht 4!</title>
<meta name="author" content="Danny">
<link rel = "stylesheet" href = "basis.css">
</head>
<body>
<h3>Naam</h3>
<p> Danny </p><br>
<h3>Geboortedatum</h3>
<p>a date</p><br>
<h3>Woonplaats</h3>
<p>A City</p>
<br><br><br>
<div class="footer">
<footer>
© 2017, Danny
</footer>
</div>
<script src="standaard.js"> </script>
<script src="test.js"></script>
</body>
</html>';
?>
right before the ending </body> tag, put your two scripts in this order:
<script id="jquery" src="standaard.js"></script>
and
<script src="test.js"></script>
You can remove id="jquery". That is not serving any purpose. You should probably just rename the file to be jquery.min.js. This is not causing you any real issue, but it makes more sense naming-wise.
in the test.js file, you can put your script:
$(document).ready(function(){
$("button").click(function(){
$("p").fadeOut("slow");
});
});
After many tries I've found the solution!
It seems quit simple and not very logic but i replaced all " to ' and it worked!?
like this:
$(document).ready(function(){
$('button').click(function(){
$('p').fadeOut('slow');
});
});
Thank you all for your response, with your help I knew what things to cross off that coulndn't be it.
I know this question has been asked many times , I have gone through all solutions but could not solve the issue.
I am new to programming and want to make a page that load some content in a div with id "content" through java script.
This is my index page
<html>
<head>
<script src="https://ajax.googleapis.com/ajax/libs/jquery/3.1.1/jquery.min.js"></script>
<script src="jquery-3.1.1.js"></script>
</head>
<body>
home
about
<div id="content">
<script src="loader.js"></script>
</div>
</body>
</html>
and this is my loader.js
$(document).ready(function() {
$('#content').load('home.html');
});
when I run index.html i get
jquery-3.1.1.js:9536 XMLHttpRequest cannot load file:///C:/Users/Desktop/my_folder/home.html.
all the files are in same folder named my_folder.
Unfortunately XMLHttpRequest can not be called to local resources, EVEN IF the HTML ist stored locally.
Its because you can programatically read the contents of local files and send them into the web, what is not allowed.
i have found the answer of my question
i have changed my script to
function load_home(){
document.getElementById("content").innerHTML='<object type="text/html" data="home.html" ></object>';
return false;
}
and call this function in content div
thanks for the help :)
I have downloaded the 1.11.3.min.js file and placed it in the same file where I have kept the HTML and script files. Before writing this code I have practiced jQuery a lot and those time I have succeeded, but this time I can't run it.
HTML
<!DOCTYPE html>
<head>
<!---<script type="text/javascript" src="image.js"></script---->
<script src="jquery-1.11.3.min.js"></script>
<script src="jquery.js"></script>
<!---<link rel="stylesheet" type="text/css" href="image.css">---->
</head>
<body onload="slideimage()">
<img src="1.jpg" id="slide" width="400px" height="400px"/>
<div id="button">
`enter code here`<button onclick="change_image()" />1</button>
</div>
</body>
</html>
jQuery
$document.ready(function(){
$("#slide").click(function(){
$(this).slideUp(400);
});
});
I have downloaded the 1.11.3.min.js file and put in the same file where i have kept the HTML and script files.Before writing this code i have practiced jQuery a lot and those time i have succeeded.But this time i have failed to run it.
Just replace this line of code
$document.ready(function(){
with this line
$(document).ready(function(){
You did't add brackets around document
May be you want do this:
$(document).ready(function(){
$("#slide").click(function(){
$(this).slideUp(400);
});
});
First, I recommend using CDN's for jQuery (less loading time), it can be found here
<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.4/jquery.min.js"></script>
then, you forgot to end your function, and you forgot () around document
your script should look like this:
$(document).ready(function() {
$("#slide").click(function() {
$(this).slideUp(400);
});
});
I'm trying to use an external JavaScript file in order to write "Hello World" into a HTML page.
However for some reason it does not work, I tried the same function and commands inline and it worked, but not when it's using an external JavaScript file. The part I commented out in the JS file was the previous method I was trying to use. Those lines of could worked when I ran the script from the header, and inline. Thanks
Html file:
<html>
<head>
</head>
<body>
<p id="external">
<script type="text/javascript" src="hello.js">
externalFunction();
</script>
</p>
<script type="txt/javascript" src="hello.js"></script>
</body>
</html>
JavaScript file
function externalFunction()
{
var t2 = document.getElementById("external");
t2.innerHTML = "Hello World!!!"
/*document.getElementById("external").innerHTML =
"Hello World!!!";*/
}
In general, you want to place your JavaScript at the bottom of the page because it will normally reduce the display time of your page. You can find libraries imported in the header sometimes, but either way you need to declare your functions before you use them.
http://www.w3schools.com/js/js_whereto.asp
index.html
<!DOCTYPE html>
<html>
<head>
<!-- You could put this here and it would still work -->
<!-- But it is good practice to put it at the bottom -->
<!--<script src="hello.js"></script>-->
</head>
<body>
<p id="external">Hi</p>
<!-- This first -->
<script src="hello.js"></script>
<!-- Then you can call it -->
<script type="text/javascript">
externalFunction();
</script>
</body>
</html>
hello.js
function externalFunction() {
document.getElementById("external").innerHTML = "Hello World!!!";
}
Plunker here.
Hope this helps.
Script tags with SRC values do not run the contents. Split it to two script tags. One for the include, one for the function call. And make sure the include is before the call.
use onload eventListener to make it simple
<script>
window.onload = function() {
externalFunction();
}
</script>
You're trying to call the function before it has been loaded.
Place the load script above the declaration:
<html>
<head>
<script type="txt/javascript" src="hello.js"></script>
</head>
<body>
<p id="external">
<script type="text/javascript">
externalFunction();
</script>
</p>
</body>
</html>
Also you have a typo:
<script type="txt/javascript" src="hello.js"></script>
Should be:
<script type="text/javascript" src="hello.js"></script>
The script type needs to be "text/javascript" not "txt/javascript".
I have an HTML page that calls a JS file. Within that JS file I need to know what the URL of the HTML page is.
So far I have this.
HTML -
<!doctype html>
<html>
<head>
<title>Untitled</title>
</head>
<body>
<script src="js/jquery.js"></script>
<script src="js/main.js"></script>
</body>
</html>
Within my main.js I have the following:
$(function() {
$ = jQuery;
window.remoteUser = "%globals_server_REMOTE_USER%";
window.targetURL = "%globals_asset_url%";
console.log(document.referrer);
});
I thought document.referrer would return the URL of the html page. However it returns a blank line in the console.
Any help would be great. Thanks
Try this,
console.log(document.URL);
OR
console.log(window.location.href);
since i read that it doesn't work in some versions of firefox
location.href used to get url the of page.
jQuery(document).ready(function(){
jQuery("#url1").html(location.href);
});
