I have been trying to develop a extension but this is getting in my way.
This is my manisfest.json
{
"manifest_version":2,
"name":"erp",
"version":"1.0",
"permissions":["storage"],
"browser_action":{
"default_popup":"popup.html"
}
}
This is my popup.html
<!DOCTYPE html>
<html>
<head>
<script scr="popup.js"></script>
</head>
<body>
<textarea id="username"></textarea><br>
<!--<input type="password" name="password" id="password"><br>
<input type="button" id="show" value="Show saved Data">-->
<input type="button" id='save' value="Save"><br>
</body>
</html>
And this is my popup.js
window.onload = function(){
document.getElementById('save').onclick = function(){
var user = document.getElementById('username').value;
alert(user);
}}
Although there is nothing to alert. Please help.
you just misspelled the src attribute.
Your Code:
<!DOCTYPE html>
<html>
<head>
<script scr="popup.js"></script>
</head>
<body>
<textarea id="username"></textarea><br>
<!--<input type="password" name="password" id="password"><br>
<input type="button" id="show" value="Show saved Data">-->
<input type="button" id='save' value="Save"><br>
</body>
</html>
Correct Code:
<!DOCTYPE html>
<html>
<head>
<script src="popup.js"></script>
</head>
<body>
<textarea id="username"></textarea><br>
<!--<input type="password" name="password" id="password"><br>
<input type="button" id="show" value="Show saved Data">-->
<input type="button" id='save' value="Save"><br>
</body>
</html>
First thing i don't know why the username is in textarea?
If you have an empty alert please notice that textarea has a different behavior to input in their value.
<input type="text" value="value">
but textarea is not like this:
<textarea id="username">value</textarea>
But both works in javascript by 'value' property as you write.
And if you have no alert i must say that your code is true(I tested) and you have a problem before this:
window.onload = func...
Put an alert before to see if it works or not:
alert('Code is true until here');
window.onload = func...

JQuery Part
I just started using JQuery. First I wanted to create a a input box with an button that alerts the text that is in that box. This is the way I wanted to do that.
$(document).ready(function() {
$('#hit').click(function() {
alert($('#term').val());
});
});
That is the code in the html body part. Here im not sure if I have to declare the id with an # or not. I tried both but It didnt work for both.
My Code
<!DOCTYPE html>
<html>
<head>
<title>Button Event</title>
<script src="cdnjs.cloudflare.com/ajax/libs/jquery/3.3.1/jquery.min.js"> $(document).ready(function() { $('#hit').click(function() { alert($('#term').val()); }); }); </script>
</head>
<body> <input id="term" type="text" value="enter your search"> <button id="hit" type="button" name="Button">Search</button> </body>
</html>
I am really new to JavaScript and Jquery. When I run this code there are no errors or something like that in the console just blank. The Button and Input field are on the website but when I enter something and click the button after that nothing happens. That´s why im sure there are some mistakes in that code.
$(document).ready(function() {
$('#hit').click(function() {
alert($('#term').val());
});
});
<script src="https://cdnjs.cloudflare.com/ajax/libs/jquery/3.3.1/jquery.min.js"></script>
<input id="term" type="text" value="enter your search" />
<button id="hit" type="button" name="Button">Search</button>
here has worked, do you have imported a jquery library?
Resolution with your code:
<!DOCTYPE html>
<html>
<head>
<title>Button Event</title>
</head>
<body> <input id="term" type="text" value="enter your search"> <button id="hit" type="button" name="Button">Search</button>
<script src="https://cdnjs.cloudflare.com/ajax/libs/jquery/3.3.1/jquery.min.js"></script>
<script>
$(document).ready(function() { $('#hit').click(function() { alert($('#term').val()); }); });
</script>
</body>
</html>
I am trying to call a function in an external JavaScript file from an HTML-file. The goal is to work with the content of a form there.
I tried so many things and always got the Error "ReferenceError: Can't find variable: X"
The positioning of the jquery javascript file loading
The positioning of the <script src="XXX"> call
Calling the function from the button "onclick" or the form "onsubmit"
Trying to call the javascript file from an embedded script in the HTML
This is what my JavaScript file and my HTML looks like right now:
function submit(e) {
answerText = document.getElementById("text").value;
// Do something with it.
}
<head>
<script src="//ajax.googleapis.com/ajax/libs/jquery/2.0.0/jquery.min.js"></script>
<script src="/scripts/debug_alerts.js" type="text/javascript"></script>
</head>
<body>
<form id="validation-form" onsubmit="return submit(e)">
<input type="text" class="form-control" name="text" id="text" placeholder="Text" required>
<button type="button" class="btn btn-primary" onclick="submit(e)">Send</button>
</form>
</body>
I also tried
function doSomething() {
// Do something
}
<head>
<script src="//ajax.googleapis.com/ajax/libs/jquery/2.0.0/jquery.min.js"></script>
<script src="/scripts/debug_alerts.js" type="text/javascript"></script>
</head>
<body>
<form id="validation-form" onsubmit="return submit(e)">
<input type="text" class="form-control" name="text" id="text" placeholder="Text" required>
<button type="button" class="btn btn-primary" onclick="submit(e)">Send</button>
</form>
<script>
function submit(e) {
doSomething();
}
</script>
</body>
In both cases, it returned the same error over and over again: "ReferenceError: Can't find variable: X". In the first example, X being "submit" and in the second "doSomething".
All help is very welcome. I know there are similar headlines here, but non of the solutions did anything for me.
Hey so when I ran the code without the e as a parameter for the submit function in the html it didn't give me the error. I think it may be because the e is the place holder for the text of the submit function in this case. Hope this helps.

Does anyone know how can I resolve the following: I want the form input by the user, to be alerted in a different HTML file.
This is what I wrote so far. It works for the id called 'name', but I dont know why it does not for the 'position'.
"index.html" file:
<script>
function myFunction() {
name = document.getElementById("name").value;
position = document.getElementById("position").value;
window.location.replace("signature.html");
return false;
}
</script>
<form class="formulario" onsubmit="return myFunction()">
Name: <input type="text" name="name" id="name"><br>
Position: <input type="text" name="position" id="position"><br>
<br>
<input type="submit" value="Generate Signature">
</form>
"signature.html" file - notice the alert(name) and the alert(position) => the alert(name) works, but not the alert(position). I want to understand how to fix that please.
<html>
<head>
</head>
<body>
<div class="signature_general">
<div class = "signature_middle">
<div id = "signature_details">
<font size="2px">Regards,</font><br>
<b><font color="#808080" size="3px" id="nameInput">Francisco Jurado</font></b><br>
<font size="2px" id="posInput">Accounting Systems Team Leader</font>
</div>
</div>
</div>
<script>
alert(name);
alert(position);
</script>
</body>
</html>
Thanks very much
Edit: I have noticed that I am getting an error, in which "position" is "undefined". Does anyone knows?
You can change your html file as:
<!DOCTYPE html>
<html lang="en">
<head>
<meta charset="UTF-8">
<title>Document</title>
</head>
<body>
<form class="formulario" action="signature.html" method="get">
Name: <input type="text" name="name" id="name"><br>
Position: <input type="text" name="position" id="position"><br>
<br>
<input type="submit" value="Generate Signature">
</form>
</body>
</html>
And your signature.html file as :
<html>
<head>
</head>
<body>
<div class="signature_general">
<div class = "signature_middle">
<div id = "signature_details">
<font size="2px">Regards,</font><br>
<b><font color="#808080" size="3px" id="nameInput">Francisco Jurado</font></b><br>
<font size="2px" id="posInput">Accounting Systems Team Leader</font>
</div>
</div>
</div>
<script>
var values = window.location.search.substring(1).split('&')
var name = values[0].split('=')[1]
var position = values[1].split('=')[1]
alert(name)
alert(position)
</script>
</body>
</html>
That name you are setting in index.html is not the same name you are printing in the alert of signature.html.
You can see this by renaming name to name2 in both places.
If you want to pass those variables from one page to another, I suggest using query strings how to exchange variables between two HTML pages?
basically i have a form which inside that form i have a textbox and a submit button, now what i want is to output text box value into console when a user type something, i found this link https://codepen.io/jnnkm/pen/WxWqwX?editors=1111 which works just perfect but when i copied the html and script code and putted it my editor and ran it trough my browser, it doesn't works at all,
here is how i tried it out:
<!DOCTYPE HTML>
<html>
<head>
<script src="JquerySock.js"></script>
<script>
function postUsernameToServer() {
console.log('executed function')
var username = $("#Registeration_Username_box").val();
console.log(username);
}
$('#Registeration_Username_box').on('input', function() {
console.log('excuted input');
postUsernameToServer();
});
</script>
</head>
<body>
<div id="Registeration_Div" class="Registeration_Div">
<form class="Registration_Form" id="Registration_Form" action="../postr" method="POST">
<div id="Registeration_Username_DIV" class="Registeration_Username_DIV">
<input type="text" id="Registeration_Username_box" class="Registeration_Username_box" placeholder="" name="UserName" maxlength="30" />
</div>
<div class="Registration_Submit_Div">
<input type="submit" value="Submit" id="SumbitForm_btn" class="SumbitForm_btn" name="Submit_btn" />
</div>
</form>
</div>
</body>
</html>
you can try it yourself too, but it didn't worked for me.
okay i found what the problem was, first i had to specify
$(document).ready(function() {
and then input my ajax code, i mean fully it was suppose to be this way
<!DOCTYPE HTML>
<html>
<head>
<script src="JquerySock.js"></script>
<script>
function postUsernameToServer() {
console.log('executed function')
var username = $("#Registeration_Username_box").val();
console.log(username);
}
$(document).ready(function() {
$('#Registeration_Username_box').on('input', function() {
console.log('excuted input');
postUsernameToServer();
});
});
</script>
</head>
<body>
<div id="Registeration_Div" class="Registeration_Div">
<form class="Registration_Form" id="Registration_Form" action="../postr" method="POST">
<div id="Registeration_Username_DIV" class="Registeration_Username_DIV">
<input type="text" id="Registeration_Username_box" class="Registeration_Username_box" placeholder="" name="UserName" maxlength="30" />
</div>
<div class="Registration_Submit_Div">
<input type="submit" value="Submit" id="SumbitForm_btn" class="SumbitForm_btn" name="Submit_btn" />
</div>
</form>
</div>
</body>
</html>
now it works perfect!
I have just started learning java script.I am trying to make Dynamic text box but the my code is not working . Can someone help me in rectifying my mistake??
<html>
<head>
</head>
<body>
<script language="javascript">
function add(){
var text=document.createElement('input');
var add=document.getElementById("Myform");
text.setAttribute("type","text");
text.setAttribute("name","BookName");
add.appendChild(text);
}
</script>
<form action="new1.php" id="Myform">
<input type="submit" value="Submit" id="submit" onclick="javascript:add();"/> <br/>
</form>
</body>
</html>
The text box disappears before I can do anything with it.
Change the input type as button or other wise it will submit the form.You want the submit button means you have to add one more button for dynamic action.
<input type="button" value="Submit" id="submit" onclick="javascript:add();"/>
You need stop submit like this:
function add(){
var text=document.createElement('input');
var add=document.getElementById("Myform");
text.setAttribute("type","text");
text.setAttribute("name","BookName");
add.appendChild(text);
}
<form action="new1.php" id="Myform" onsubmit="event.preventDefault();">
<input type="submit" value="Submit" id="submit" onclick="javascript:add();"/> <br/>
</form>
Try this plunker
<!DOCTYPE html>
<html>
<head>
<link rel="stylesheet" href="style.css">
<script src="script.js"></script>
</head>
<body>
<form action="new1.php" id="Myform">
<input type="button" value="Submit" id="submit" onclick="add();"/> <br/>
</form>
</body>
</html>
JS
function add(){
var text=document.createElement('input');
var add=document.getElementById("Myform");
text.setAttribute("type","text");
text.setAttribute("name","BookName");
add.appendChild(text);
}
