Event binding on dynamically created elements?
(23 answers)
Closed 7 months ago.
Thank you in advance for any help! :)
I am using javascript to add fields to a document but the element monitor only works on hard coded fields.
For example in the code below, lozfield is monitored for change which works fine initially.
However, if you click the populate button and repopulate with exactly the same input field, the watch no longer works.
In debug, the field has EVENT next to it... until it is repopulated at which point the EVENT disappears.
(apologies for my probably incorrect terminology!).
$("#lozfield").change(function() {
alert("lozfield-CHANGED");
});
$("#populate").click(function() {
document.getElementById("lozcontainer").innerHTML = '<input type="text" id="lozfield" value="ABC">';
});
<script src="https://cdnjs.cloudflare.com/ajax/libs/jquery/3.3.1/jquery.min.js"></script>
<div id="lozcontainer">
<input type="text" id="lozfield" value="ABC">
</div>
<input id="populate" type="button" value="POPULATE">
You need to delegate your event to a higher element - which in your case I'd suggest is lozcontainer
$("#lozcontainer").change("#lozfield", function() {
alert("lozfield-CHANGED");
});
$("#populate").click(function() {
document.getElementById("lozcontainer").innerHTML = '<input type="text" id="lozfield" value="ABC">';
});
<script src="https://cdnjs.cloudflare.com/ajax/libs/jquery/3.3.1/jquery.min.js"></script>
<div id="lozcontainer">
<input type="text" id="lozfield" value="ABC">
</div>
<input id="populate" type="button" value="POPULATE">

I have a form for which has fields like card no ,card holders name,expiry date and stuff i want something like whenever i am filling the form it should be displayed side by side before storing it to database ,any help?
Bind it to a jQuery keyup event
<form>
Card No:</br>
<input type="number">
<input type="submit" value="submit">
</form>
<p id="display">
</p>
<script>
$(document).ready(function () {
$(":number").keyup(function () {
$("#display").text($(":number").val());
});
});
</script>
Here is a really easy solution in vanilla js;
let input = document.getElementById('in');
input.onkeyup = () => {
document.getElementById('p').innerHTML = input.value;
}
<input id='in' type='text'>
<p id='p'></p>

JQuery change not firing until blur

I need help with strange behavior of my javascript/jQuery code.
jQuery .change() of simple text input executes only if i click on page or chrome console or press some key on keyboard, but not when i type text in my text input.
Sure, I expect, that code will be executed after each change in text input, but now this looks like:
I type something in text input
Nothing happens
I click anywhere in the document or press a key, let's say, "tab"
Code runs as expected
Can someone explain me whats going on?
Му code is simple:
$('#search_field').change(function() {
alert("test")
})
<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script>
<input type="text" name="search_field" class="form-control" id="search_field" placeholder="Search" />
if you want to show on type use on('input')
$('#search_field').on('input',function() {
alert($(this).val())
})
<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script>
<input type="text" name="search_field" class="form-control" id="search_field" placeholder="Search" />

How to place the cursor (auto focus) in text box when a page gets loaded without javascript support?
(7 answers)
Closed 5 years ago.
I would like to fill an input without having to select it with my mouse before. Just using javascript and not Jquery .
What I mean is that they user just have ton type his answer and it goes directly into the input. Here is my HTML.
<input id="inputresponse" name="response" type="text" value="" />
I have searched everywhere but I can't find a clue. I guess we should use either keyup or keypress, but I can't find how.
Your help is highly appreciated, thanks !
Use Autofocus on HTML tag as -
<input id="inputresponse" name="response" type="text" autofocus>
Another Way, You can use js also -
window.onload = function() {
var input = document.getElementById("inputresponse").focus();
}
<input id="inputresponse" name="response" type="text">
This should work:
$('#inputresponse').focus();
Just setting this on your page will automatically focus on the input element and anything typed will be added within.

Use jQuery to change value of a label
(4 answers)
Closed 8 years ago.
I have a input box that when the user type a sentence it will pass it to a empty box(div).I have some of the code where I grab the value, but I can't figured out how to pass that data one by one to the empty box every time they click submit.
<input type="text" class="form-control border" id="skills-box">
$( ".btn-add" ).click(function() {
value = $("#skills-box").val();
$(value).append( $(".label-primary"));
});
You need to append the value to the element class, in this case taht would be the .label-primary div tag. It would go something like this.
$(".btn-add").click(function() {
var value = $("#skills-box").val();
$('.label-primary').append(value);
});
I got it working in jsbin, here is the link:
EXAMPLE
use this script
$('.skills-box').on('blur',function(e){
$('.display-box').append(this.value);
});
Complete Code:
Jquery
<body>
<input type="text" placeholder="Type Here..." class="skills-box">
<div class="display-box"></div>
<script type="text/javascript">
$('.skills-box').on('blur',function(e){
$('.display-box').append(this.value);
});
</script>
</body>
</html>
Change $(value).append( $(".label-primary")); to:
$(value).appendTo( ".label-primary" );

Dynamically creating a specific number of input form elements

Original close reason(s) were not resolved
Im always used to using jquery or other javascript frameworks but right now I have no frameworks to use so i wanted to see if anyone knows how i can do this in straight javascript if possible.
Basically i have a div like this
<input type="button" id="more_fields" onclick="add_fields();" value="Add More" />
<div id="room_fileds">
<div class='label'>Room 1:</div>
<div class="content">
<span>Width: <input type="text" style="width:48px;" name="width[]" value="" /><small>(ft)</small> X </span>
<span>Length: <input type="text" style="width:48px;" namae="length[]" value="" /><small>(ft)</small</span>
</div>
</div>
What i need one is when the add more button is clicked i need to basically add more width and length fields either creating a entire structure like the one above with all the divs or just inserting new span tag with the fields below the existing ones.
I know how to do it with jquery or prototype framework but unfortunatley I cannot use any frameworks for this. Does anyone have any idea how to do it. I would post code iv done for this but I dont even know where to beging.
You can use the innerHTML property to add content. Add a id="wrapper" to the div surrounding your span elements and then you can do
var dummy = '<span>Label: <input type="text"><small>(ft)</small></span>\r\n';
document.getElementById('wrapper').innerHTML += dummy;
Of course you don't need the id and can use other DOM methods to get to the div, but I find using ids easier and cleaner. Here's a quick fiddle
Also note that you shouldn't inline your css code, neither attach your javascript calls directly inside the DOM elements. Separating DOM, Javascript and CSS will make your life easier.
Don't need create new room?.
var room = 1;
function add_fields() {
room++;
var objTo = document.getElementById('room_fileds')
var divtest = document.createElement("div");
divtest.innerHTML = '<div class="label">Room ' + room +':</div><div class="content"><span>Width: <input type="text" style="width:48px;" name="width[]" value="" /><small>(ft)</small> X</span><span>Length: <input type="text" style="width:48px;" namae="length[]" value="" /><small>(ft)</small></span></div>';
objTo.appendChild(divtest)
}
Demo: http://jsfiddle.net/nj4N4/7/
just use the innerHTML like this:
btw I changed div class="content" to id="content" you can add new id if you prefer.
function add_fields() {
var d = document.getElementById("content");
d.innerHTML += "<br /><span>Width: <input type='text'style='width:48px;'value='' /><small>(ft)</small></span> X <span>Length: <input type='text' style='width:48px' value='' /><small>(ft)</small</span>";
}
