Hide bootstrap alert if empty don´t work - javascript

I want to hide my bootstrap alert if it is empty. It hide correctly when page load, problem is when I do a push who insert data into div, it don´t show alert and it keep with display = none
HTML
<div id="a1" class="alert alert-success">
<div id="discussion"></div>
</div>
JS:
<script type="text/javascript">
hideAlert("a1");
function hideAlert(id) {
var text = $('#' + id + '#discussion').text();
console.log(text.length);
if (text.length <= 0)
$('#' + id).hide();
}
</script>
Edit
I try it using input event , it occurs same. It hide but it don't show when get value
JS:
<script type="text/javascript">
$('#discussion').keyup(function () {
// If value is not empty
if ($(this).val().length == 0) {
// Hide the element
$('#a1').hide();
} else {
// Otherwise show it
$('#a1').show();
}
}).keyup();
</script>

Your selector must be #a1 #discussion no #a1#discussion.So:
Change :
$('#' + id + '#discussion')
To:
$('#' + id + ' #discussion')
^-----------------
hideAlert("a1");
function hideAlert(id) {
var text = $('#' + id + ' #discussion').text();
console.log(text.length);
if (text.length <= 0)
$('#' + id).hide();
}
<link rel="stylesheet" href="https://maxcdn.bootstrapcdn.com/bootstrap/3.3.7/css/bootstrap.min.css">
<script src="https://ajax.googleapis.com/ajax/libs/jquery/3.2.1/jquery.min.js"></script>
<div id="a1" class="alert alert-success">
<div id="discussion"></div>
</div>
After Update your question:
setInterval(function(){ hideAlert("a1"); }, 3000);
function hideAlert(id) {
var text = $('#' + id + ' #discussion').text();
if (text.length <= 0)
$('#' + id).hide();
}
<link rel="stylesheet" href="https://maxcdn.bootstrapcdn.com/bootstrap/3.3.7/css/bootstrap.min.css">
<script src="https://ajax.googleapis.com/ajax/libs/jquery/3.2.1/jquery.min.js"></script>
<div id="a1" class="alert alert-success">
<div id="discussion" contenteditable="true">Some Text...</div>
</div>
Note : Remove text in div and see result

Why not try using the :empty css pseudo-class like this:
CSS
#discussion{
display: block;
}
#discussion:empty{
display: none;
}
HTML
<div id="discussion" class="alert alert-success"></div>
Note: The beginning and closing tags should be next to each other for the pseudo-class to work (like the beginning and closing div tags next to each other without any line breaks or space in the html shown above).

jQuery UI draggable doesn't work on created element

Draggable function works on other already created elements, but not on the one i'm creating within a function after submit button.
I've checked if i'm adding an id to 'li' elements and it works, so why can't I drag it?
It works when I use it on whole 'ul' element.
HTML:
<div class="container">
<form>
<input type="text" id="entry">
<button id="entryButton">button</button>
</form>
<ul id="list">
</ul>
</div>
$("#entryButton").click(function(){
event.preventDefault(); //stops refreshing
var query = $("#entry").val();
if (query !== "") {
var registry = "<div id='drag'>" + query + "</div>"
$("#list").append(registry)
$("#entry").val("");
return false; //also stops refreshing
console.log(registry);
}
})
$("#drag").draggable({
axis: "y"
});
You can only use an id once, so I would suggest that you use class for that. Furthermore, you should add the draggable to the element after creation, as Ferhat BAŞ has said.
https://jsfiddle.net/exqn1aoc/2/
$("#entryButton").click(function(){
event.preventDefault(); //stops refreshing
var query = $("#entry").val();
if (query !== "") {
var registry = "<div class='drag'>" + query + "</div>"
$("#list").append(registry);
$('#list').children().last().draggable();
$("#entry").val("");
return false; //also stops refreshing
console.log(registry);
}
});
Just use class instead of id for multi pal created item to drag and put your draggable inside button click.
$("#entryButton").click(function() {
event.preventDefault(); //stops refreshing
var query = $("#entry").val();
if (query !== "") {
var registry = "<div id='drag' class='drag'>" + query + "</div>"
$("#list").append(registry)
$("#entry").val("");
$(".drag").draggable({
axis: "y"
});
return false; //also stops refreshing
console.log(registry);
}
})
<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script>
<script src="https://ajax.googleapis.com/ajax/libs/jqueryui/1.12.1/jquery-ui.js"></script>
<div class="container">
<form>
<input type="text" id="entry">
<button id="entryButton">button</button>
</form>
<ul id="list">
</ul>
</div>
First you need to put the draggable() function inside your click function.
Second, do not use id . Duplicate id's are not valid HTML and that's what causing only the first #drag to be draggable. Use class instead
See snippet below
$("#entryButton").click(function() {
event.preventDefault(); //stops refreshing
var query = $("#entry").val();
if (query !== "") {
var registry = "<div class='drag'>" + query + "</div>"
$("#list").append(registry)
$("#entry").val("");
$(".drag").draggable()
return false; //also stops refreshing
console.log(registry);
}
})
.drag {
height: 100px;
width: 100px;
background: red;
}

<div class="container">
<form>
<input type="text" id="entry">

I can't make this JavaScript count working

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>

hide div tag where id with jquery and mvc

How to hide div where id with jquery and mvc?
<div class="List-Display">
#for(int i=1;i<=10;i++)
{
<div id="#i">
<span>content</span>
</div>
<button onclick="display(#i)" type="button">
}
</div>
I've tried the following but not worked!
<script>
function display(parameters) {
$('.List-Display').find('div[id!=' + parameters + ']').hide();
//or
$('.List-Display').filter('div[id!=' + parameters + ']').hide();
}
</script>
I need to hide div tag where id!=parameters. But I have no idea!!
You can do this:
$('.List-Display').find('div:not("#'+ parameters + '")').hide();
i use :
$('.List-Display').children('div:not("#' + parameters + '")').hide();
. its worked;

Check to see if a div exists

I have the following code:
<html>
<head>
<script type="text/javascript" src="//ajax.googleapis.com/ajax/libs/jquery/1.10.2/jquery.min.js"></script>
</head>
<body>
<span></span>
<div class="content" id="2">
<div class="reply"></div>
</div>
<div class="content" id="1">
</div>
<div class="content" id="3">
<div class"reply"></div>
</div>
<script>
var n = $( ".reply" ).length;
$( "span" ).text( "There are " + n + " divs.");
</script>
</body>
</html>
I am trying to write a jQuery script that will check individual divs with unique id's to see if it contains the "reply" div. I have code to see if the "reply" div exists at all working. I am new to jQuery so I am unsure how to go about this.
var n = $( ".reply" ).length;
$( "span" ).text( "There are " + n + " divs.");
Use #uniqueId .reply jQuery selector:
alert("The id with id '3' contains" + $("#3 .reply").length + ".reply divs.");
To check if a particular Id containing .reply div:
if($("#id .reply").length>0)
{
//reply exist in this id
}
Above code works like this
$("#id .reply").length
returns the occurrence of .reply in #id selector.
If present then return 1 else return 0.
You are on correct path, if you want to check for unique id use #elementId
if($("#ID .reply").length > 0)
{
//div exists
}

Using JQuery how to show and hide different div's onClick event

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(){
$(".slider_area").show(1000);
$("#show").css("display","none");
$("#hide").css("display","block");
});
});
</script>
Add the code above into the header portion and the code below in the body portion.
<img src="images/hide-banner.png" id="hide" class="link right"/>
<img src="images/show-banner.png" id="show" class="link right dis" />
The code is ready for the different image click for show and hide div.
<div id="div_<%=id>">
</div>
<div id="Hide_<%=id>" style="display:none;">
</div>
<div id="div_<%=id>">
</div>
<div id="Hide_<%=id>" style="display:none;">
</div>
<div id="div_<%=id>">
</div>
<div id="Hide_<%=id>" style="display:none;">
</div>
<div id="div_<%=id>">
</div>
<div id="Hide_<%=id>" style="display:none;">
</div>
<script>
var temp = 0;
var temp1 = 0;
$("#div_<%=id>").click(function(){
if (temp1 == 0) {
$('#' + temp).hide();
temp = 'Hide_<%=id>';
$('#Hide_<%=id>').show();
temp1 = 1;
}
else{
$('#' + temp).hide();
temp = 'Hide_<%=id>';
$('#Hide_<%=id>').show();
temp1 = 0;
}
});
</script>
