I want to modify the below code so that selected_users remains unique after append. That is, let's append a user U to selected_users only if selected_users does not already contain a U.
The below code you can copy and paste and it will work. All dependencies are on cdns.

$(document).ready(function() {
$("#add").on("click", function() {
var users = $("#users > p.selected");
var selected_users = $("#selected_users");
selected_users.append(users.clone().removeClass("selected"));
});
$("#remove").on("click", function() {
var selected_users = $("#selected_users > p");
selected_users.remove();
});
$("p").click(function() {
if( $(this).hasClass("selected") ) {
$(this).removeClass("selected");

<div id="users">
<p class="1">User 1</p>
<p class="2">User 2</p>
<p class="3">User 3</p>
<p class="4">User 4</p>
<p class="5">User 5</p>
</div>
<div>
<input type="button" value=">>" id="add"/>
<input type="button" value="<<" id="remove"/>
</div>
<div id="selected_users">
</div>
You could do something like this:
$("#add").on("click", function()
{
var users = $("#users > p.selected");
var selected_users = $("#selected_users");
if(!selected_users.find(users).lenght())
{
selected_users.append(users.clone().removeClass("selected"));
}
});
Forms like this commonly remove the item from the source list when adding it to the target list.
This sort of behavior would prevent the need to do the check, as it would be impossible to add the duplicate to your selected_users list.
Your code would look something like this for selecting/deselecting a user:
$("#add").on("click", function() {
var users = $("#users > p.selected");
var selected_users = $("#selected_users");
selected_users.append(users.clone().removeClass("selected"));
users.remove();
});
$("#remove").on("click", function() {
var selected_users = $("#selected_users > p");
var users = $("#users");
users.append(selected_users.clone());
selected_users.remove();
});
NOTE: I have not tested the above code.
If you wanted to maintain the order of users in each of your list, you could do a sort on either list when adding to it, or you could maintain the visibility property of each user rather than actually removing/adding them from either list.
Simple solution is to remove form the list on the left hand side.
If you don;t want to do that. Try this. The idea is to assign ids to be able to check.
$("#add").on("click", function() {
var users = $("#users > p.selected");
users.uniqueId();//assigns unique id if they don't have one
//you can do above step somewhere else also for performance reasons
var selected_users = $("#selected_users");
selected_users.append(users.clone().removeClass("selected"));
users.each(function(user) {
var id = user.attr('id');
var exists = $("#selected_users > [selectedid="+id+"]);
if (! exists || exists.length <= 0 ) {
selected_users.append(
user.removeClass("selected").
removeAttr("id").
attr('selectedid',id));
}
});
});

I'm very new to JQuery.
I already can, get the data from textbox and do some calculation and show it to other 'textbox' though I want to post it to 'div' or 'p' whatever it is as long as not textbox.
here's my code
<div id="result" style="display:none;">
<div class="col-sm-5 text-right"><label>Participant fee (IDR):</label></div>
<div class="col-sm-7"id="parcost" ></div>
<div class="col-sm-5 text-right"><label>Populi fee (IDR):</label></div>
<div class="col-sm-7"><input type="text" id="popcost"></div>
<div class="col-sm-5 text-right"><label>Total Estimated Cost (IDR):</label></div>
<div class="col-sm-7"><input type="text" id="totcost"></div>
</div>
$(document).ready(function(){
$('#calc').click(function(){
var num_participant = parseInt($("num_participant").val());
var reward = parseInt($("reward").val());
var esttime = parseInt($("esttime").val());
var parcost = num_participant*reward;
var popcost = (parcost*0.1)+(num_participant*150);
var totcost = parcost+popcost;
/*
document.getElementById("result").style.display = "block";
document.getElementById("parcost").value = parcost;
document.getElementById("popcost").value = popcost;
document.getElementById("totcost").value = totcost;*/
document.getElementById("result").style.display = "block";
$("#parcost").html(parcost);
$("#popcost").html(popcost);
$("#totcost").html(totcost);
return false;
});
});
Still wont work, if I change it from "document.getelementById" to "$".
and even using "document.getelementById" it won't showed on the "div".
any ideas?
I'm not sure if you're asking this but try something like this,
var totCost = document.getElementById("totcost").value;
$("#yourDivID").html(totCost);
I'm not sure what you are asking about but if you want to send the result to a div, just use $("#divId").html(result)
I think that you must use .text or .html in place .value.
look at this example using jquery:
<!doctype html>
<html lang="en">
<head>
<meta charset="utf-8">
<title>text demo</title>
<style>
p {
color: blue;
margin: 8px;
}
b {
color: red;
}
</style>
<script src="https://code.jquery.com/jquery-1.10.2.js"></script>
</head>
<body>
<p><b>Test</b> Paragraph.</p>
<p></p>
<script>
var str = $( "p:first" ).text();
$( "p:last" ).html( str );
</script>
</body>
</html>
If you wish to add a result in a div try with:
jQuery("#divID").append("<p>" + data + "<p>");
To update the content of a <div> or <p> element, you would use innerHTML instead of value.
So in your sample code you would update this line:
document.getElementById("parcost").value = parcost;
into this:
document.getElementById("parcost").innerHTML= parcost;
Furthemore, since you are already using jQuery, you can simplify your click function:
$('#calc').click(function(){
var num_participant = parseInt($("#num_participant").val());
var reward = parseInt($("#reward").val());
var esttime = parseInt($("#esttime").val());
var parcost = num_participant*reward;
var popcost = (parcost*0.1)+(num_participant*150);
var totcost = parcost+popcost;
$("#result").css("display", "block");
$("#parcost").html(parcost);
$("#popcost").val(popcost);
$("#totcost").val(totcost);
});
I want to make a button (out of divs) and a paragraph (or any text field) below the divs that counts the clicks.
$(document).ready(function() {
$('#butt').mousedown(function() {
$("#butt").hide();
});
$("#pushed").mouseup(function() {
$("#butt").show();
});
$("#butt").click(function() {
button_click();
});
});
var clicks = 0;
function button_click() {
clicks = parseInt(clicks) + parseInt(1);
var divData = document.getElementById("showCount");
divData.innerHTML = "Clicks:" + clicks;
}
<!-- <link type="text/css" rel="stylesheet" href="CSS.css"/> -->
<form name="ButtonForm">
<div id="container">
<div id="pushed"></div>
<div id="butt"></div>
</div>
<div id="showCount"></div>
<script src="http://ajax.googleapis.com/ajax/libs/jquery/3.1.1/jquery.min.js" type="text/javascript"></script>
<!--<script src="Untitled-1.js" type="text/javascript"></script>-->
</form>
Your div elements are empty and there is no CSS to give them any explicit size, so they will never be visible for you to click on them.
Also, the mousedown event handler can and should be combined with the click handler for butt and the mouseup event handler should just be a click event as well.
Additionally, you only need to update the number of clicks, not the word "Clicks", so make a separate placeholder for the number with a span element and then you can hard-code the word "Clicks" into the div.
Lastly, to increment a number by one, you can just use the pre or post-increment operator (++).
$(document).ready(function() {
var clicks = 0;
var divData = $("#clickCount");
$("#pushed").on("click", function() {
$("#butt").show();
});
$("#butt").on("click", function() {
$("#butt").hide();
clicks++; // increment the counter by one
divData.html(clicks);
});
});
#pushed, #butt {height:50px; width:150px; background-color:green; margin:5px;}
<body>
<form name="ButtonForm">
<div id="container">
<div id="pushed"></div>
<div id="butt"></div>
</div>
<div id="showCount">Clicks <span id="clickCount"></span></div>
<script src="http://ajax.googleapis.com/ajax/libs/jquery/3.1.1/jquery.min.js" type="text/javascript"></script>
</form>
</body>
First of all, you should simplify your code. Hiding and showing the button is not necessary to produce the result you are looking for.
Second, change the #butt element to an actual button so that you have something to see and click.
Third, make sure your script is loading after jquery is included.
<script src="http://ajax.googleapis.com/ajax/libs/jquery/3.1.1/jquery.min.js" type="text/javascript"></script>
<button id="butt">I'm a button</button>
<div id="showCount"></div>
<script>
$(document).ready(function() {
$("#butt").click(function() {
button_click();
});
var clicks = 0;
function button_click() {
clicks = parseInt(clicks) + parseInt(1);
var divData = document.getElementById("showCount");
divData.innerHTML = "Clicks:" + clicks;
}
});
</script>
Twitter's submit tweet textbox highlights the characters that are over the character limit:
As you can see, the characters that overrun the character limit are highlighted in red. How can I achieve something like this?
You'll find the necessary solution and required code here:
How to insert <em> tag when exceeding 140 limit i.e. going negative?
...and here:
REGEX - Highlight part over 19 chars
Your question appears to be duplicitous.
Note: I didn't have the option to post the above links as a comment (i.e. privilege contingent on reputation).
Here's the code as per Simon Kuang's recommendation (see comments):
HTML:
<!DOCTYPE html>
<html>
<head>
<script src="http://ajax.googleapis.com/ajax/libs/jquery/1.10.1/jquery.min.js"></script>
<meta charset=utf-8 />
<title>JS Bin</title>
</head>
<body>
<h3>Your text here</h3>
<div contenteditable="true" id="myDiv">edit me
</div>
<p>
<h3>Stuff over 19 characters</h3>
<div id="extra">
</div>
<p>
<h3>Sample output</h3>
<div id="sample">
</div>
</body>
</html>
CSS:
.highlight {
color:red;
}
JavaScript:
$(document).ready(function() {
$('#myDiv').keyup(function() {
var content = $('#myDiv').html();
var extra = content.match(/.{19}(.*)/)[1];
$('#extra').html(extra);
var newContent = content.replace(extra, "<span class='highlight'>" + extra + "</span>");
$('#sample').html(newContent);
});
});
Here is the example, show alert when the limit is reached and thereafter highlight all the characters entered.
$(document).ready(function() {
var input = $('#text_text');
var warning = $('#warning');
var char_limit = 30;
input.on('keyup', function() {
var val = $(this).val();
if (val.length > parseInt(char_limit)) {
alert("limit reached");
warning.html('hello').css('display', 'block');
l = val.length
var input = document.getElementById("text_text");
input.setSelectionRange(char_limit, l);
input.focus();
} else {
warning.css('display', 'none');
}
});
});
#warning {
display: none;
}
<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script>
<div id="test_box">
<textarea name="msg" cols="50" rows="5" id="text_text"></textarea>
<div id="warning"></div>
</div>
Try this (pattern)
html
<data></data><br />
<textarea maxlength="20" placeholder="20 character limit"></textarea>
js
$(function () {
$(document).on("keyup", "textarea", function (e) {
if ($(e.target).val().length >= 20) {
$("data").text($(e.target).attr("placeholder"))
.fadeIn(1000).fadeOut(9000);
};
});
});

I'm new to JavaScript and jQuery. I'm trying to figure out how to obtain my checkbox checked labels to eventually send to the next web page. I also want to send a complete list of checked and non-checked boxes to the next web page so I thought I'd just store them in an array to start, but the array isn't working to display it.
The way this checkbox list page works is that after the user is done checking, they hit the button and the results are captured to send on.
I started a function to do this, but I'm trying to use an array with the complete list of checkbox labels to use for display and to send on later. I'm having trouble getting the array to display the label name, and I can't help but think I'm not doing this right, or that there's a better way to do it. I'm capturing the checked value (on) when I used inpfields[i].value, but I really need the checked item's label. When I used inpfields[i].label, it returned nothing. I also tried lblFields[i].label and it was empty too.
My questions are:
What do you recommend I do with the array to get it to work in the checkbox label?
How do I get the array of checked items for use later?
I got the idea for pressing the button for checkbox processing here. I'm trying to understand arrays here but don't have it working yet. I got the idea to use the getLabel(id) function methodology here but it's not working.
Right now, when I hit my button, I get a popup that says [object HTMLCollection] on it.

I figured it out. I wound up using:
if(inpfields[i].type == 'checkbox' && inpfields[i].checked == true) selchbox.push(lblFields[i].innerHTML);
Thanks for the hint!
This is how I got an array of allLabels. I didn't use getheading(i) in my label anymore. I'm just using text for the labels, pulling the names into an array, and then I'll figure out how to send the array to the next web page.
function getSelectedChbox(frm) {
// JavaScript & jQuery Course - http://coursesweb.net/javascript/
var selchbox = []; // array that will store the value of selected checkboxes
var allLabels = []; // array to store value of all checkboxes, selected and not
// gets all the input tags in frm, and their number
var inpfields = frm.getElementsByTagName('input');
var lblFields = frm.getElementsByTagName('label');
var allLabelFields = frm.getElementsByTagName('label').innerHTML;
var nr_inpfields = inpfields.length;
// traverse the inpfields elements, and adds the value of selected (checked) checkbox in selchbox
for(var i=0; i<nr_inpfields; i++) {
if(inpfields[i].type == 'checkbox' && inpfields[i].checked == true) selchbox.push(lblFields[i].innerHTML);
if(inpfields[i].type == 'checkbox') allLabels.push(lblFields[i].innerHTML);
}
alert(allLabels);
return selchbox;
}
I would like to show a div based on the Onclick event of an link.
First Click - Show div1
Second Click - Hide remaining div's and Show div2
Third Click - Hide remaining div's and show div3
Fourth Click - Hide remaining div's and show div1 => repeat the loop and goes on..
Code Follows:
<div class="toggle_button">
Toggle
</div>
<div id='div1' style="display:none;">
<!-- content -->
</div>
<div id='div2' style="display:none;">
<!-- content -->
</div>
<div id='div3' style="display:none;">
<!-- content -->
</div>
Jquery Code :
$(document).ready(function() {
$("#toggle_value").click(function(){
$("#div1").show("fast");
$("#div2").show("fast");
$("#div3").show("fast");
});
});
The above code shows all divs on first click itself but it should show div1 on first click as mentioned.
I'll try my shot.
EDIT:
After second though, to avoid global variable use it's better to do the following
$(document).ready(function() {
$("#toggle_value").click((function(){
var counter = 0;
return function()
{
$("#div" + counter).hide("fast");
counter = (counter % 3) + 1;
$("#div" + counter).show("fast");
}
})());
});
You should add a counter in the function.
$(document).ready(function() {
var count = 0;
$("#toggle_value").click(function(){
if (count == 0) {
$("#div1").show("fast");
$('#div2').hide();
count++;
}
else if (count == 1) {
$("#div2").show("fast");
...
count++;
}
else if (count == 2) {
$("#div3").show("fast");
....
count++;
}
else {
$('div').hide();
count=0;
}
});
});
How about this
Working Example here - add /edit to URL to edit the code
$('html').addClass('js'); // prevent hiding divs on DOM ready from 'flashing'
$(function() {
var counter = 1;
$('#toggle_value').click(function() {
$('div','#container')
// to stop current animations - clicking really fast could originally
// cause more than one div to show
.stop()
// hide all divs in the container
.hide()
// filter to only the div in question
.filter( function() { return this.id.match('div' + counter); })
// show the div
.show('fast');
// increment counter or reset to 1 if counter equals 3
counter == 3? counter = 1 : counter++;
// prevent default anchor click event
return false;
});
});

This could easily be wrapped up in a plugin
A simple way would be to introduce a variable that tracked clicks, so something like this:
var tracker = 0;
$(document).ready(function() {
$("#toggle_value").click(function(){
if(tracker == 0)
{
$("#div1").show("fast");
}else if(tracker ==1)
etc etc
tracker ++;
});
});
My solution is a little different - I'd do it dependant on the state of the divs at the current time (on click). See below for what I mean by this.
$(document).ready(function() {
$("#toggle_value").click(function(){
if ($("#div1).is(':visible')) { // Second click
// Hide all divs and show d2
$("#div1").hide();
$("#div2").show("fast");
$("#div3").hide();
$("#div4").hide();
} else if ($("#div2").is(':visible')) { // Third click
// follow above example for hiding all and showing div3
} else if ($("#div3").is(':visible')) { // Fouth click
// follow above example for hiding all and showing div1
} else { // first click
// All divs should be hidden first. Show div1 only.
$("#div1").show("fast");
}
});
});
Just to warn you - I have not tested this code :)
Based upon the following for determining visibility: http://docs.jquery.com/Frequently_Asked_Questions#How_do_I_determine_the_state_of_a_toggled_element.3F
Hope it helps
I prefer to use "filter" method and make a little easier work with counter:
(function () {
var divCounter = 0, divs;
$(function () {
divs = $('#div1, #div2, #div3');
$('#toggle_value').click(function (e) {
divs.hide() // hide other divs
.filter(function (index) { return index == divCounter % 3; }) // select appropriate div
.show('fast'); // and show it
divCounter++;
});
});
})();
I would probably do something like: (The following assumes all your <div>s are in a container with id "container")
$(document).ready(function() {
var $allDivs = $("#container > div");
var counter = 0;
$("#container > div").click(function(){
counter = counter < $allDivs.length - 1 ? counter + 1 : 0;
$allDivs.not(":eq("+counter +")").hide("fast");
$allDivs.eq(counter).show("fast");
});
});
The .toggle function in jQuery takes any number of argument functions, so the problem is already solved. See the docs under Events.
$("#toggle_value").click(function()
{
$("#div" + (++c) % 3).show().siblings().hide();
}
var c = 1;
$("#toggle_value").click(function()
{
$("#div" + c).hide("fast");
$("#div" + ++c).show("fast");
if (c > 3) c=1;
});
First You have to add query basic file:
<script src="http://ajax.googleapis.com/ajax/libs/jquery/1.3.2/jquery.min.js"></script>
Then you have to add the following code:
<script type="text/javascript">
$(document).ready(function () {
$("#hide").click(function(){
$(".slider_area").hide(1000);
$("#show").css("display","block");
$("#hide").css("display","none");
});
$("#show").click(function(){
