I have two forms .. each form has a reser button with the id called "formReset"
no all the form are showing in the same time, one shows after the other one
I used the below code but it only works on the first form, I can o it by doing two click buttons with different id's but is there a way to do it with one click only?
document.getElementById("formReset").addEventListener("click",resetForm);
function resetForm(){
document.getElementById("login").reset();
document.getElementById("cal").reset();
}
<form id="login">
<label>Enter your name : <span id="nameMsg"></span></label><br>
<input type="text" id="name"><br>
<input type="submit" id="submit" value="submit" >
<input type="button" id="formReset" value="reset" ><br>
</form>
<form id="cal">
<input type="number" id="answer" ><br><br>
<input type="button" id="submit2" value="submit2" >
<input type="button" id="formReset" value="reset" >
</form>
try this
document.querySelectorAll(".formReset").forEach(btn=>{
btn.addEventListener("click",resetForm)
});
function resetForm(e){
e.target.parentElement.reset()
}
<form id="login">
<label>Enter your name : <span id="nameMsg"></span></label><br>
<input type="text" id="name"><br>
<input type="submit" id="submit" value="submit" >
<input type="button" class="formReset" value="reset" ><br>
</form>
<form id="cal">
<input type="number" id="answer" ><br><br>
<input type="button" id="submit2" value="submit2" >
<input type="button" class="formReset" value="reset" >
</form>
Attribute id should be unique in a document, use class instead with querySelectorAll() and forEach() like the following way:
document.querySelectorAll(".formReset").forEach(function(reset){
reset.addEventListener("click",resetForm);
});
function resetForm(){
document.getElementById("login").reset();
document.getElementById("cal").reset();
}
<form id="login">
<label>Enter your name : <span id="nameMsg"></span></label><br>
<input type="text" id="name"><br>
<input type="submit" id="submit" value="submit" >
<input type="button" class="formReset" value="reset" ><br>
</form>
<form id="cal">
<input type="number" id="answer" ><br><br>
<input type="button" id="submit2" value="submit2" >
<input type="button" class="formReset" value="reset" >
</form>
easy way using closest.
document.querySelectorAll(".formReset").forEach(btn=>{
btn.addEventListener("click",resetForm)
});
function resetForm(e){
e.target.closest('form').reset()
}
<form id="login">
<label>Enter your name : <span id="nameMsg"></span></label><br>
<input type="text" id="name"><br>
<input type="submit" id="submit" value="submit" >
<input type="button" class="formReset" value="reset" ><br>
</form>
<form id="cal">
<input type="number" id="answer" ><br><br>
<input type="button" id="submit2" value="submit2" >
<input type="button" class="formReset" value="reset" >
</form>
You should add click listeners for each reset button, then reset parent by click
.html
<form id="login">
<label>Enter your name : <span id="nameMsg"></span></label><br>
<input type="text" id="name"><br>
<input type="submit" id="submit" value="submit">
<input type="button" class="formReset" value="reset"><br>
</form>
<form id="cal">
<input type="number" id="answer"><br><br>
<input type="button" id="submit2" value="submit2">
<input type="button" class="formReset" value="reset">
</form>
.js
document.querySelectorAll(".formReset").forEach((e) => {
e.addEventListener("click", () => {
document.querySelectorAll("form").forEach((f) => {
f.reset();
})
});
});

I want to get value of input fields with dynamic id to jquery function
<input type="text" id="a_8" name="a_8" value="12">
<input type="text" id="b_8" name="b_8" value="22">
<button type="button" class="btn btn-success" onclick="javascript:det(8);">Submit</button>
<input type="text" id="a_9" name="a_9" value="22">
<input type="text" id="b_9" name="b_9" value="52">
<button type="button" class="btn btn-success" onclick="javascript:det(9);">Submit</button>
Jquery function
function det(a)
{
//how can I get values of id a_8,b_8 when first button is clicked
and a_9,b_9 values when second button is clicked
}
you can simply create id of your control by appending method argument a to a_ or b_ like $("#a_"+a).val()
function det(a)
{
alert($("#a_"+ a ).val());
alert($("#b_"+ a ).val());
}
<script src="https://cdnjs.cloudflare.com/ajax/libs/jquery/3.3.1/jquery.min.js"></script>

console.log('values: '+b1+','+b2);

I have multiple forms on one page with same structure.
They all have a file input field that has 'onchange' event, which removes the 'disabled' attribute from my submit button when a file is chosen.
The problem is, my function only works for the first element with that class name. How can I make it work for every item with that class?
index.php:
<form class="form">
<input type="file" name="image" onchange="unlock();">
<input type="text" name="title" placeholder="Image title"/>
<input type="submit" value="Add image" class="submit" disabled/>
</form>
<form class="form">
<input type="file" name="image" onchange="unlock();">
<input type="text" name="title" placeholder="Image title"/>
<input type="submit" value="Add image" class="submit" disabled/>
</form>
scripts.js:
function unlock() {
document.querySelector('.submit').removeAttribute("disabled");
}
Any help is appreciated!
Use eventListener
address relatively using selectors
make it a habit to never call anything submit in a form
document.querySelectorAll("[name=image]").forEach(
ele => ele.addEventListener("change",
(e) => e.target.closest(".form").querySelector(".sub").disabled = false
)
);
<form class="form">
<input type="file" name="image">
<input type="text" name="title" placeholder="Image title" />
<input type="submit" value="Add image" class="sub" disabled/>
</form>
<form class="form">
<input type="file" name="image">
<input type="text" name="title" placeholder="Image title" />
<input type="submit" value="Add image" class="sub" disabled/>
</form>
More compatible version
[...document.querySelectorAll("[name=image]")].forEach(function(ele) {
ele.addEventListener("change",
function(e) {
e.target.parentNode.querySelector(".sub").disabled = false;
})
});
<form class="form">
<input type="file" name="image">
<input type="text" name="title" placeholder="Image title" />
<input type="submit" value="Add image" class="sub" disabled/>
</form>
<form class="form">
<input type="file" name="image">
<input type="text" name="title" placeholder="Image title" />
<input type="submit" value="Add image" class="sub" disabled/>
</form>
Give ID's to all submit buttons and pass the respective ID's in unlock() function.
This removes the disabled from the submit
function unlock(form_id) {
document.getElementById(form_id).removeAttribute("disabled");
}
<form class="form">
<input type="file" name="image" onchange="unlock('form1');">
<input type="text" name="title" placeholder="Image title" />
<input type="submit" id="form1" value="Add image" class="submit" disabled/>
</form>
<form class="form">
<input type="file" name="image" onchange="unlock('form2');">
<input type="text" name="title" placeholder="Image title" />
<input type="submit" id="form2" value="Add image" class="submit" disabled/>
</form>
I am creating an onscreen keyboard, and want a function which will allow when any of the buttons are pressed, for their values to appear in a text box to the side of the keyboard. The code I have so far is:-
<script type="text/javascript">
function onclick(){
document.getElementById("output").value
=document.getElementById("Q").value;
}
</script>
And the HTML code below:-
<div class ="Row">
<div class="Box2">
<form id="keyboard" name="keyboard">
<div>
<input type="button" onclick='onclick' id="Q" value="Q">
<input type="button" value="W">
<input type="button" value="E">
<input type="button" value="R">
<input type="button" value="T">
<input type="button" value="Y">
<input type="button" value="U">
<input type="button" value="I">
<input type="button" value="O">
<input type="button" value="P">
</div>
<div>
<input type="button" value="A">
<input type="button" value="S">
<input type="button" value="D">
<input type="button" value="F">
<input type="button" value="G">
<input type="button" value="H">
<input type="button" value="J">
<input type="button" value="K">
<input type="button" value="L">
</div>
<div>
<input type="button" value="Z">
<input type="button" value="X">
<input type="button" value="C">
<input type="button" value="V">
<input type="button" value="B">
<input type="button" value="N">
<input type="button" value="M">
</div>
<div>
<input type="button" value="SPACE">
<input type="button" value="ENTER">
</div>
</form>
<input type='text' id='output' />
</div>
</div>
</div>
You have it tagged as jQuery, so here is a more elegant jQuery solution: Throw that code away and use a single delegated jQuery event handler. Start with something like this:
$('[name=keyboard]').on('click', 'input[type=button]', function(){
var value = $(this).attr('value');
$('#output').val($('#output').val() + value);
});
JSFiddle: https://jsfiddle.net/TrueBlueAussie/kaau601u/
Obviously you need to handle the SPACE and ENTER as special cases, but you gave no clues what you are doing next, so leaving that to the reader to finish :)
Notes:
You either need to place this code after the elements it references or put it in a DOM ready handler.
Like this:
$(function(){
$('[name=keyboard]').on('click', 'input[type=button]', function(){
var value = $(this).attr('value');
$('#output').val($('#output').val() + value);
});
});
Or you can use a document attached handler, which is always present:
Like this:
$(document).on('click', 'input[type=button]', function(){
var value = $(this).attr('value');
$('#output').val($('#output').val() + value);
});
//Please try this working example
$('#Q').click(function(){
$('#output').val($(this).val());
console.log($(this).val());
})

I have made a slight change in the output field type with working SPACE and ENTER
jQuery('form[name="keyboard"] input[type="button"]').click(function(){
var inpVal = jQuery(this).val();
if( inpVal == "SPACE" ){
inpVal = ' ';
}else if( inpVal == "ENTER" ){
inpVal = '\n';
}
var val = jQuery('#output').val() + inpVal;
jQuery('#output').val(val);
});

Using just javaScript and no need for jQuery.
This example including the use of the SPACE and ENTER keys. As a bonus I added a BACKSPACE key.
Note your output text field was changed to text area to allow for the use of the enter key.
Create a single event listener for the form. This can be done using document query selector.
Capture the click event with the query selector.
Note on the <body> tag we add the onload event handler so when the document is served up the event listener is assigned to the <form> node.
Any click inside the <form> will be tested

I have made form and it is hidden using CSS display property. I have button. I want to show the form when I click that button. I have done everything from my end but still form does not show up.
<input type="button" value="Popup" onclick="showLoginForm();"/>
<form id="loginForm" action="" method="post" style="display:none;">
<p><strong>ID:</strong> </p>
<strong>Name: *</strong> <input type="text" id="Name" name="Name" /><br/>
<strong>Number: *</strong> <input type="text" id="Number" name="Number" /><br/>
<strong>Email: *</strong> <input type="text" id=""="Email" name="Email" /><br/>
<input type="submit" id = "submit" name="submit" value="Submit">
</form>
Below is my JS function which is not trigerring.
$("button").click(function(e) {
$("#loginForm").show();
e.preventDefault();
});
The function showLoginForm() is not defined. Your jquery was listening for a button click, when your button is of type input.
$("input[type=button]").click(function(e) {
$("#loginForm").show();
e.preventDefault();
});
<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.0.0/jquery.min.js"></script>
<input type="button" value="Popup" />
<form id="loginForm" action="" method="post" style="display:none;">
<p><strong>ID:</strong> </p>
<strong>Name: *</strong> <input type="text" id="Name" name="Name" /><br/>
<strong>Number: *</strong> <input type="text" id="Number" name="Number" /><br/>
<strong>Email: *</strong> <input type="text" id=""="Email" name="Email" /><br/>
<input type="submit" id = "submit" name="submit" value="Submit">
</form>
Or with the function defined:
function showLoginForm(){
$("#loginForm").show();
}
<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.0.0/jquery.min.js"></script>
<input type="button" value="Popup" onclick="showLoginForm();"/>
<form id="loginForm" action="" method="post" style="display:none;">
<p><strong>ID:</strong> </p>
<strong>Name: *</strong> <input type="text" id="Name" name="Name" /><br/>
<strong>Number: *</strong> <input type="text" id="Number" name="Number" /><br/>
<strong>Email: *</strong> <input type="text" id=""="Email" name="Email" /><br/>
<input type="submit" id = "submit" name="submit" value="Submit">
</form>
Your issue is that your input is type button, not a button element itself.
so either changing your input to a button or changing your jquery binding to $('input[type=button]') ought to work
