I am really new to javascript objects.
Here is my code:
(function(){
var homenavmenu = {
nav:$('.navMenuButton'),
target:$(this).attr('href'),
test:function(){
// alert(homenavmenu.target)
homenavmenu.nav.click(function(){
alert(1);
return false;
})
}
}
homenavmenu.test();
})()
Why doesn't it work? It won't alert(1);
Here is my HTML:
<div class="navMenu">
market
my
</div>
Working Demo http://jsfiddle.net/5JmdD/3/
PLease check your html again, demo is working with what you need.
Behavior: click on the button and you will get alert.
Hope this helps :)
code
$(function(){
var homenavmenu = {
nav:$('.navMenuButton'),
target:$(this).attr('href'),
test:function(){
// alert(homenavmenu.target)
homenavmenu.nav.click(function(){
alert(1);
return false;
})
}
}
homenavmenu.test();
})()
HTML
<input type="button" value="hulk" class="navMenuButton" />
ok it seems like you can't use
nav:$('.navMenuButton'),
should use
nav:'.navMenuButton',
invoke as
$(homenavmenu.nav).click(function(){
alert(1)
})
this work for me,but i don't know why it worked in the example above.

HTML:
<input class="test removeMe" type="text">
jQuery:
$(function () {
function isEmpty() {
if (!$(".test").val()) {
$(this).removeClass("removeMe");
} else {
$(this).addClass("addMe");
}
}
isEmpty();
});
Please, tell me, where am I wrong?
I want isEmpty to fire on load/reload and check if the input has value. If it doesn't, it will remove the removeMe class. If it does have some value, it will add addMe class to it.
Console is empty, I can't figure it out why this isn't working properly.
Update:
Very odd... It does fire proper alert relatively if it is empty or not, but doesn't add/remove classes.

Update 02
It does work, but not exactly...
https://jsfiddle.net/37tt3x72/2/
The this isn't working... if replace it with the targeted element, than it will work. So the question is remained: Why this isn't working here?
Call function from document on ready function.
function isEmpty() {
if (!$(".test").val()) {
$(this).removeClass("removeMe");
} else {
$(this).addClass("addMe");
}
}
$(document).ready(function(){
isEmpty();
});
$(function () {
function isEmpty() {
if (!$(".test").val()) {
alert("Empty");
$(this).removeClass("removeMe");
} else {
alert("not Empty");
$(this).addClass("addMe");
}
}
isEmpty();
});
<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script>
<input class="test removeMe" type="text">
Rory McCrossan provided with great and informative answer here: Why "$(this)" doesn't work in the following example
And adeneo pointed out on another SO question/answers about how this works: How does the "this" keyword work?
would you explain please, why this code is showing alert window with the text at the end of radio element:
<script>
function markReply(el){
alert(el.nextSibling.nodeValue);
}
$(document).ready(function(){
markReply();
});
</script>
and this one does not:
<script>
function markReply(el){
return el.nextSibling.nodeValue;
}
$(document).ready(function(){
var msg = markReply();
alert(msg);
});
</script>
there are 4 optional answers selected by radio element, like:
<input type="radio" name="choise" onclick="markReply(this);"/>....some text
Thank you!
The second script just returns the value, without doing anything with it.
Note that in both cases, the call from the document ready function is useless, and probably produces an el is not defined error in the console.
You're not passing any parameters to the markReply() function when you created a variable for it.
Try this:
var msg = markReply(el);
The script that does not alert the message is not working because the parameter of the function markReply is not there when the jquery is loaded.
HTML
<input type="radio" name="choise" id="choise"/>....some text
JS
$(document).ready(function(){
$("#choise").click(function () {
alert(markReply(this));
});
});
function markReply(el){
return el.nextSibling.nodeValue;
}

i would like to create a one-page website where on click of the button the impressum-div will fade in. Another Click on the same button would then fadeOut the impressum-div.
I already managed it to fadeIn the div on click.
But when I try to use "if" the whole thing doesn't work anymore.
I already found some tipps here and tried them all but nothing really worked for me..
Here my Script-Code:
<script type="text/javascript">
$(document).ready(function() {
function display() {
if (document.getElementById("impressum").style=="none") {
$('#impressum').fadeIn();
}
if (document.getElementById("impressum").style=="block") {
$('#impressum').fadeOut();
}
}
});
</script>
I tried this in several versions (with .click() and so on..), so this is probably totally wrong.
Here my HTML-Code:
<input type="button" id="iButton" value="Impressum" onclick="javascript:display()"/>
<div id="impressum" style="display:none">
<p>Here Impressum</p></div>
Help is very much appreciated, if you could post a complete Function it would bethe best because i am only putting parts wildly together..
Greetings
Just use fadeToggle()
<input type="button" id="iButton" value="Impressum" onclick="javascript:display()" />
<div id="impressum" style="display:none">
<p>Here Impressum</p>
</div>
then
$(document).ready(function () {
$('#iButton').click(function () {
$('#impressum').stop(true).fadeToggle();
})
});
Demo: Fiddle
HTML
<div id="impressum" style="display:none">
<p>Here Impressum</p>
</div>
JavaScript
$('#iButton').click(function () {
$('#impressum').stop(true).fadeToggle();
});

You cannot retrieve the display value like that, you need to use window.getComputedStyle:
var elem = document.getElementById("impressum"),
display = window.getComputedStyle(elem,null).getPropertyValue("display");
Fiddle Demo
/* 1: <div onclick="display(this);"></div>*/
var display = function(elm){
var status = G(elm).attrib('data-display')||'false';
if(status=='false'){
G(elm).css({display:'block'});
G(elm).attrib('data-display', 'true');
return false;}
if(status=='true'){
G(elm).css({display:'none'});
G(elm).attrib('data-display', 'false');
return false;}
};
/* 2 */
/* elm.onclick = display;*/
var display = function(ev){
var elm = this||G(ev).source(); //Choice
var status = G(elm).attrib('data-display')||'false';
if(status=='false'){
G(elm).css({display:'block'});
G(elm).attrib('data-display', 'true');
return false;}
if(status=='true'){
G(elm).css({display:'none'});
G(elm).attrib('data-display', 'false');
return false;}
};
I am trying to check whether or not a particular element has been clicked but am having trouble doing so. Here is my HTML:
<div id="my_special_id" class="switch switch-small has-switch" data-on="success" data-off="danger">
<div class="switch-on switch-animate"><input type="checkbox" checked="" class="toggle">
<span class="switch-left switch-small switch-success">ON</span>
<label class="switch-small"> </label>
<span class="switch-right switch-small switch-danger">OFF</span>
</div>
</div>
Here is my jQuery:
<script type="text/javascript">
$(document).ready(function() {
$('#my_special_id').click(function() {
if ($('#my_special_id div:first-child').hasClass('switch-on')) {
window.alert('ON!');
}
});
});
</script>
I am guessing that my id "my_special_id" is not what is actually being clicked?
I guess click event should have event parameter.
$(document).ready(function() {
$('#my_special_id').click(function(e) {
if (e.target check condition) {
window.alert('ON!');
}
});
});
parameter 'e' above specified is the event object that has all info about click event.
so if u check all info under 'e.tartget', u will be able to find out which one is clicked.
Hope it's helpful for you.
Cheers :)
Since you are looking for a alert when the checkbox is clicked
$(document).ready(function() {
$('#my_special_id input.toggle').click(function() {
if ($('#my_special_id div:first-child').hasClass('switch-on')) {
window.alert('ON!');
}
});
});
Demo: Fiddle
Simply put alert when you click on that particular class switch-on
<script type="text/javascript">
$(document).ready(function() {
$('#my_special_id div:first-child .switch-on').on('click',function() {
window.alert('ON!');
});
});
</script>
Or even try like
$(document).ready(function() {
$('#my_special_id').click(function() {
if ($(this + 'div:first-child').hasClass('switch-on')) {
window.alert('ON!');
}
});
});
This JavaScript works for me.
$(document).ready(function() {
$('#my_special_id').click(function() {
if ($('#my_special_id div:first-child').hasClass('switch-on')) {
alert("On!");
}
});
});
You are sure you have JQuery?
Your code looks fine I think either you have a syntax error somewhere else or you do not have JQuert.
does this alert?
$(document).ready(function() {
alert("Jquery works");
});
The click event will trigger to whatever you're bound do. the only time you'd have to be worried is if you bound to both a parent and child (e.g. you had listed #my_special_id,.switch-small--then you'd have to look at e.target).
With that said, you can use scope to limit how jQuery finds the div:first-child. I'm not 100% sure what you're after, but the below appears to do what you're after:
$(document).ready(function() {
$('#my_special_id').click(function() {
// look for div:first-child within `this` (where `this=#my_special_id`
// per the .click selector above)
if ($('div:first-child',this).hasClass('switch-on')) {
window.alert('ON!');
}
});
});
If you're looking to bind to the on/off separately, you may want to change it around a bit. we can still check for .switch-on, just have to traverse differently:
// here we bind to the on/off buttons and not the container
$('#my_special_id .switch-small').click(function(){
// you want the facsimilee of `div:first-child`, so (because we're now
// within that node, we use .parent() to get back up to it
var $firstChild = $(this).parent();
if ($parent.hasClass('switch-on')){
alert('ON!');
}
});
I use old javascript code to flip my search button from search to searching in my forms as follows
<div id="search_clickable"> <input class="search" type="submit" value="search" onClick="javascript:flipSearchButton();"></div>
<div id="search_unclickable" class="hidden"><img src="/assets/img/searching.png" alt=""></div>
My javascript function is
function flipSearchButton()
{
document.getElementById('search_clickable').style.display = 'none';
document.getElementById('search_unclickable').style.display = 'block';
}
How to I achieve this with jQuery?
function flipSearchButton(){
$('#search_clickable').hide(); // or - $('#search_clickable').toggle();
$('#search_unclickable').show(); // or - $('#search_unclickable').toggle();
}
And stop using inline javascript:
$('.search').click(flipSearchButton);
Note that your search button is of type submit (?!) so it will submit the form, You probably want to change the type to button or return false from the callback:
function flipSearchButton(){
$('#search_clickable').hide();
$('#search_unclickable').show();
return false;
}
include jquery:
<script type="text/javascript" src="jquery.js"></script>
then:
function flipSearchButton()
{
$('#search_clickable').hide();
$('#search_unclickable').show();
}
i thought something like this:
$("#search_clickable").click(function() {
$("#search_clickable").hide();
$("#search_unclickable").show();
});
if you wanna toggle this element, use toggle() instead of hide() and show().
You can also consider to use fade effect to improve user experience
function flipSearchButton()
{
$('#search_unclickable').fadeIn('slow', function() {
// Animation complete
});
$('#search_clickable').fadeOut('slow', function() {
// Animation complete
});
};
You don't even need a separate function:
$("input[type=submit").click(function() {
$("#search_clickable").hide();
$("#search_unclickable").show();
});
Or use the id/class of the submit button if you want to on a specific button:
$(".search").click(function() {
$("#search_clickable").hide();
$("#search_unclickable").show();
});
Please refer below URL for toggle Div.
