I'm using this javascript code to get the path of a file, but every time when I run the code, the path appears as "C:\fakepath\file". I think that it is a browser issue (I'm using Chrome), but before changing the browser settings, I wonder if there is any way to do the same procedure without having this error. Is there any javascript library to perform this procedure correctly? How can we fix this error code?
<!DOCTYPE html>
<html>
<head>
<script type="text/javascript">
function showFileName() {
var fil = document.getElementById("myFile");
alert(fil.value);
}
</script>
</head>
<body>
<form id="frmMain" name="frmMain">
<input type="file" id="myFile" name="myFile"/>
Show Name
</form>
</body>
</html>
As always, thank you very much for the help. :)

I am trying to make a very simple thing work:
<!DOCTYPE html>
<html lang="en">
<head>
</head>
<body>
<script src="js/test.js" type="text/js"></script>
<button onclick="test()" type="submit">Test</button>
</body>
</html>
With js/test.js being found by the browser and containing:
function test() {
alert("test");
}
When opening the page and clicking the button, nothing happens and I can see in the console:
Uncaught ReferenceError: test is not defined
at HTMLButtonElement.onclick (test:7)
I have tried to move the script import above or under the button, or in the header.
I have tried to use "window.setlocale = function" in my js file.
I have tried to put nothing in the test method.
I checked for errors with JSLint (there is no error).
When I check the source, I can see the js file and the browser opens it when I click on it.
The only way I can get the Javascript to work is to write it inline...
Maybe the issue is with my environment?
In order to run this, I use an Apache server, and it is configured to serve this on localhost:8077. I works fine so far.
I use Laravel 7.10, PHP 7.4... working fine. To run this I created a simple route, that shows the view (a simple index.blade.php) with the HTML content copy/pasted above. It displays fine on "http://localhost:8077/test", no problem.
I also tried to use the laravel notation
<script src="{{ asset('js/test.js') }}" type="text/js"></script>
but it gives the same result.
I also have the PHP debugbar (a Laravel plugin) active, and it does not show any error. The view is properly loaded and displayed.
Also, I use PHPStorm, and it does not detect any issue.
It's been 2 days and I cannot makes this seemingly extremely basic thing to work, please help me m(_ _)m
Your script type is wrong. Use application/javascript in your script element to make your javascript work - or better yet, remove the type attribute and let browsers auto-detect the type:
<!DOCTYPE html>
<html lang="en">
<head>
</head>
<body>
<script src="js/test.js" type="application/javascript"></script>
<button onclick="test()" type="submit">Test</button>
</body>
</html>
Without type attribute:
<!DOCTYPE html>
<html lang="en">
<head>
</head>
<body>
<script src="js/test.js"></script>
<button onclick="test()" type="submit">Test</button>
</body>
</html>
you can try to add script tag to header tag. like this
<head>
<script type="text/javascript" src="path/to/script.js"></script>
<!--other script and also external css included over here-->
</head>
Try removing the function name in js/test.js
function() {
alert("test");
}
Please add the js file as a reference in the header section of your core file. External referencing.
Code on webpageThe button doesn't workSo, I am fairly new to JavaScript and have been looking at tutorials for the language. I downloaded the Atom IDE and began following a video and used the same code as the video to make a web page with a button that reveals a message when clicked. However when I click the button nothing happens, and when I hit inspect element.
It gives me the following error: Failed to load resource: net::ERR_FILE_NOT_FOUND
It appears as though the HTML file is not working with the .js file. However they are in the same directory.
Here's the updated code (still the same error):
<DOCTYPE! html>
<html>
<head>
</head>
<body>
<button onclick="revealMessage()">Click me!</button>
<p id="hiddenMessage" style="display:none">Filosofem</p>
</body>
<script>
function revealMessage() {
document.getElementById("hiddenMessage").style.display = 'block';
}
</script>
</html>
Perhaps, it is the file directory. When you declared <script src="js/script.js"></script>, that means that your script.js file, must be located in a subfolder called "js".
If you want your to be within your file, then you can do
<DOCTYPE! html>
<html>
<head>
</head>
<body>
<button onclick="revealMessage()">Click me!</button>
<p id="hiddenMessage" style="display:none">Filosofem</p>
</body>
<script>
function revealMessage() {
document.getElementById("hiddenMessage").style.display = 'block';
}
</script>
</html>
Finally, you should try resaving the code through atom, and make sure your code is the right version of your code.
By using an external stylesheet you need to make sure your CSS file is saved as said above but with <script scr="filename.js">/script> I still haven't found a way other than having your code internal which is completely fine unless you're making a world wide website then it would be easy to hack.
I created a javascript file, made a function, and then linked my html file with it in the head. It worked. When I copy and pasted the exact same thing into a php file, the function suddenly doesn't work. I need a way to make the function work in the php file.
This is the javascript function:
function showField(){
if(document.getElementById("downtown").checked && document.getElementById("pricerange").value == "100"){
document.getElementById("newField").removeAttribute("hidden");
}
}
This is the php where i try to call the function:
<input type="button" name = "search" value="Search" id="search" onclick="showField();">
This is in my head where I linked the javascript file:
<script src = "a3q5.js"></script>
Seeing that I don't know what the rest of your code is, I would just make sure you have the normal HTML stuff:
<!DOCTYPE html>
<html>
<head>
<title></title>
</head>
<body>
<input type="button" name = "search" value="Search" id="search" onclick="showField();">
<script src = "a3q5.js"></script>
</body>
</html>
Hope this helps!
The simple way would be here, Put this to your PHP. It worked for me
<?php
// your code
echo '<script src = "a3q5.js"></script>';
// your code
?>
Hello I am new to JavaScript. I have looked through other posts but I cannot resolve my issue.
Earlier I was attempting to play around with the following script found here (How to read text file in JavaScript).
I got it working successfully SEVERAL times:
<!DOCTYPE html>
<html>
<head><meta charset="utf-8" />
<title>Read File (via AJAX)</title>
<script type="text/javascript">
var reader = new XMLHttpRequest() || new ActiveXObject('MSXML2.XMLHTTP');
function loadFile() {
reader.open('get', 'test.txt', true);
reader.onreadystatechange = displayContents;
reader.send(null);
}
function displayContents() {
if(reader.readyState==4) {
var el = document.getElementById('main');
el.innerHTML = reader.responseText;
}
}
</script>
</head>
<body>
<div id="container">
<input type="button" value="test.txt" onclick="loadFile()" />
<div id="main">
</div>
</div>
</body>
</html>
While testing this script, all of a sudden it stopped working! I have assured that my content blockers are disabled and javascript is enabled on my web browsers. I am not sure if I locked up my web browsers ability to use javascript while using this XMLHTTPREQUEST or possibly overloaded it. I even tried inserting a reader.abort() function to possibly close the request if it was still open somehow. I tried inserting alert() functions to troubleshoot that did not work. I tried restarting my computer that did not work. I am using a MAC and have tried the latest versions of Firefox, Chrome, and Safari which all do not work with javascript now.
It is so bad that I CAN'T even get this simple javascript example to work.
<!DOCTYPE html>
<html>
<head>
<title>Test</title>
<script type=“text/javascript”>
document.write(“<h1>This is a test</h1>”);
</script>
</head>
<body>
</body>
</html>
PLEASE HELP! I don't know what I did or how to fix the issue.
Above script works only if you're loading the text file from a server. Make sure the file is located in the same place as your html file on the server and load the page with your server address. Most likely thing you're doing wrong is you're trying to access client's file. It doesn't work because that will be HUGE security breach, only the client can send you a file to read (If that is your intended purpose, then I advise you to use FileReader, example code can be found here).
About your second script, you're using “ instead of ".
The question is trivial, but I'm dumb as rock with JS, and I'd like to save myself some of the precious time I need. For some reasons, nothing happens when I call a method from a javascript file in HTML:
<!DOCTYPE html>
<html>
<head>
</head>
<body>
<script src = "game.js"></script>
<button onclick = "init()">Start</button>
</body>
</html>
And game.js:
function init(){
alert("external fn clicked");
}
Needless to say, the alert does not appear as expected. What am I missing?
The reason was entirely trivial - the console is actually useful (ctrl+shift +j on Windows and Chrome). The js did not load properly due to a syntax error.
