I have on the html page an and elements, created dynamically via js.
<input type="text" id="MyInput" name="MyInput"
class='form-control copyMe' placeholder="enter smth pls"/>
<div id="jsonTextAreaDiv" contenteditable="true">
<span id="MyInput_JSON"></span>
</div>
And I want to have text binding from input to span.
So, I go with next JS:
$(document).on('input', 'input.copyMe', function(){
var valToInsert = $(this).val();
var idToInsert = $(this).attr("id") + "_JSON";
document.getElementById(idToInsert).innerHTML = valToInsert;
});
Could be all in one line jquery, but... Anyway.
This binding works fine during entering text to input.
But once input looses focus - suddenly span looses inner text.
I don't know why. This is exactly my question, how is it happening?
I've "worked around" this issue with adding
$(document).on('input', 'input.copyMe', function(){
var valToInsert = $(this).val();
var idToInsert = $(this).attr("id") + "_JSON";
document.getElementById(idToInsert).innerHTML=valToInsert;
}).on('blur', '.copyMe', function(){
var valToInsert = $(this).val();
var idToInsert = $(this).attr("id") + "_JSON";
document.getElementById(idToInsert).innerHTML=valToInsert;});
This way it works like I want it. But this is ridiculous.
Any ideas regarding why does the value disappear from span at the first place?
Thanks in advance.
Change your input event to use the change event instead. IE does not support the 'input' event correctly. Alternatively, you could try using the keyup event.
$(document).on('change', 'input.copyMe', function(){
var valToInsert = $(this).val();
var idToInsert = "#" + $(this).attr("id") + "_JSON";
$(idToInsert).html(valToInsert);
});
Also, i changed your last line to jQuery as well. There's no reason to mix jQuery and pure JS together. It makes it easier to read if you keep it uniform.

I am not very familiar with javascript/Jquery Syntax, I would like to bind 2 input text fields that were dynamically added to a table inside a loop. The main goal is to automatically fill the second text field with text from the first one. I was able to do it for 2 static text field by doing that.
$(document).bind('input', '#changeReviewer', function () {
var stt = $('#changeReviewer').val();
stt = stt.replace(/ /g,'.')
$("#changeReviewerEmail").val(stt + "##xxxxxx.com");
});
I have tried a few things but when I try to get the value of the first input, it always returns empty. Thanks.
Check this code
$(document).on('input', '#changeReviewer', function() {
var stt = $('#changeReviewer').val();
stt = stt.replace(/ /g, '.');
$("#changeReviewerEmail").val(stt + "##xxxxxx.com");
});
$('#addbtn').click(function() {
$('div').empty().append(`<input id='changeReviewer'><input id='changeReviewerEmail'>`);
});
<script src="https://cdnjs.cloudflare.com/ajax/libs/jquery/3.3.1/jquery.min.js"></script>
<div>
<button id='addbtn'>add inputs</button>
</div>
I have this textbox
{{ Form::text('horasT', $horasT, array('class'=>'input-block-level', 'placeholder'=>'0.00')) }}
I want to update a Label when the textbox value changes.
this is the label:
<label id="subTotal" name="subTotal">0</label>
My Jquery is this:
jQuery('#horasT').on('input', function (){
var valT = $('#horasT').val();
$('#subTotal').value = valT;
});
It doesn't seem to work and I've tried a lot of things so far.
But for me this should work... What seems to be the problem? The label just sits in 0 no matter the value that is in the textbox
The event is change and a label has text not value
Possible other event to trigger on: "input change keyup keypress cut paste mouseup focus blur"
jQuery(document).on('change', '#horasT', function (){
var valT = $(this).val();
$('[name="subTotal"]').text(valT);
});
<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.0/jquery.min.js"></script>
<label for="horasT" name="subTotal">0</label>
<input id="horasT" type="text">
jQuery("#horasT").change(function() {
$("#subTotal").text($(this).val());
});
I found a lot of info about this, but I haven't foundanything that could help me yet.
My problem is that I have got a div with its id and it supposes to be a container (#cont_seguim).
I have a menu on the right side which contains circles (made by css and filled with text), like following:
<div class="circle_menu b">
<div class="text_menu n">ECO</div>
</div>
where b and n are the format for background and text.
When I click a circle, this one must be added to the container (notice that each circle has got its own text), but I can't get that.
I made and array and used alert() to test that click works, and it does, but append() doesn't even work to print text, and I don't know why.
<script type="text/javascript">
var arrayS = new Array();
$(document).ready(function() {
$(".circulo_menu").click(function() {
var text = $(this).text();
alert("calling " + text);
$("#cont_seguim").append(text);
});
return text;
});
</script>
Thank you for your responses!
Your code seems to work fine (if you fix the different class name used in html vs script circulo_menu vs circle_menu)
Demo at http://jsfiddle.net/7jbUj/
To add the whole circle append the whole element and not its text by using .append(this)
$(".circle_menu").click(function() {
$("#cont_seguim").append(this);
});
Demo at http://jsfiddle.net/7jbUj/1/
To add a copy of the circle, so you can add multiple of them use the .clone() first..
$(".circle_menu").click(function() {
var clone = $(this).clone(false);
$("#cont_seguim").append(clone);
});
Demo at http://jsfiddle.net/7jbUj/3/
Inside the click handler, this refers to the clicked element. And since you bind the click handler on the circle_menu element, this refers to that. You can use it directly for the appending or clone it to make a copy first..
unable to understand properly, hope below one can help you.
<script type="text/javascript">
$(document).ready(function() {
$(".circulo_menu").click(function() {
var myText = $(this).html();
alert("calling " + myText);
$("#cont_seguim").html(myText);
});
});
</script>
make sure classname and id name will remain same as html
Try using html() instead of text().
Try this: Demo
HTML:
<div class="circle_menu b">
<div class="text_menu n">ECO</div>
</div>
<div id="cont_seguim"></div>
Javascript:
$(document).ready(function() {
$(".circle_menu").click(function() {
var text = $(this).html();
console.log("calling " + text);
$("#cont_seguim").append(text);
});
});
Try this:
$( ".container" ).append( $( "<div>" ) );
source
use
$("#container").append($("<div/>", {id:"newID",text:"sometext"}));
You could try
<script type="text/javascript">
var arrayS = new Array();
$(document).ready(function() {
$(".circulo_menu").click(function() {
var text = $(this).text();
alert("calling " + text);
$("#cont_seguim").append($(this).html());
});
return text;
});
</script>
By this way the clicked circle element get added to div
I am using the following code
$(document).on('click', '#editDetailBtn', function () {
var input = $('<input id="#detailprimaryDescription" type="text" />');
input.val($('#detailprimaryDescription').text());
$('#detailprimaryDescription').replaceWith(input);
$('#editDetailBtn').hide();
$('#detailPrimaryCancel').show();
$('#detailPrimarySave').show();
});
$(document).on('click', '#detailPrimaryCancel', function () {
var input = $('<div id="#detailprimaryDescription" ></div>');
//input.val($('#detailprimaryDescription').text());
$('#detailprimaryDescription').replaceWith(input);
$('#editDetailBtn').show();
$('#detailPrimaryCancel').hide();
$('#detailPrimarySave').hide();
});
what I am trying to achieve is to once cancel is clicked then it will turne the input field back into a div

I think this is what you're shooting for.
JS FIDDLE
you don't need to place '#' at the beginning of an id in the dom, its only used to reference elements.
so basically, every where you had something like:
var input = $('<input id="#detailprimaryDescription_input" type="text" />');
you shouuld be doing something like:
var input = $('<input id="detailprimaryDescription_input" type="text" />');
once I cleaned that up it worked as it does in the fiddle.
I do want to say, that it would be a muchhhhhhh better practice to just show and hide a div containing all those inputs rather than manipulating the DOM to create / destroy them constantly.
I want to select the id of the current div when I click on it in jQuery.
For example, say I have HTML like this:
<div class="item" id="10">hello world</div>
<div class="item_10">hello people</div>
When I click on the first div on .item class, I want to copy the id of the current div + adding to it the number (10), so it will be ("div id" + 10) equal to the second dev class = item_10.
I tried to use currentid = this.id; but it doesnt work :( !
First, note that id attributes starting with numbers are syntactically illegal in HTML4. If you're using id="10" make sure that you're using the HTML5 doctype (<!DOCTYPE html>).
It's hard to say why what you were doing didn't work without seeing your actual code. Presumably it is because you were registering for the event on a higher element (like the body) and this.id was the id of that higher element and not the element you clicked on.
In this case, you want to use the target property of the event to find what you clicked on. For example:
$(document.body).click(function(evt){
var clicked = evt.target;
var currentID = clicked.id || "No ID!";
$(clicked).html(currentID);
})
Seen in action: http://jsfiddle.net/Gra2P/
If you were registering on the specific elements instead, then this.id does work:
$('div').click(function(evt){
var currentID = this.id || "No ID!";
$(this).html(currentID);
})
Seen in action: http://jsfiddle.net/Gra2P/1/
This is sub-ideal, however, because:
It makes many event handler registrations instead of 1, and
If additional divs are added to the document after this code is run, they will not be processed.
Under jQuery 1.7, you use the .on method to create a single event handler on a parent element with selectors for the kinds of elements you want to catch the event on, and have this set to them. In code:
$(document.body).on('click','div',function(evt){
var currentID = this.id || "No ID!";
$(this).html(currentID);
})
Seen in action: http://jsfiddle.net/Gra2P/2/
I think you're trying to do something like:
$(".item").click(function(){
var id = $(this).attr("id");
var el = $(".item_" + id);
});
Now el is your second div.
You can simply use this.id
$('div').click(function() {
var divid = this.id;
alert($('.item_'+divid).html());
});
Demo
Something like this?:
$('div').click(function() {
theId = $(this).attr('id');
//Do whatever you want with theId.
});
This can be done as:
$('.item').click(function() {
var divId = $(this).attr("id");
});
