I have a small test. When I click on the "click" button, the display is good which changes the color, but console.log shows that the code is not working according to the logic I put in.
In the beginning, the color is black, that's correct
I clicked the button the color turn to red, that's correct
but looking at the console, I think "show bar" must be shown first.
I may do something wrong, or my logic was wrong. Please help me.
function hideShow() {
const footer = document.getElementById("footer");
authorInfo = document.getElementById("authorInfo");
if (footer.style.display === "none") {
footer.style.display = "block";
authorInfo.style.display = "none";
console.log("show bar");
} else {
footer.style.display = "none";
authorInfo.style.display = "flex";
console.log("hide bar");
}
}
<div id="footer" class="item" style="
width: 100px;
height: 200px;
background-color: black;
display: flex;
"></div>
<div id="authorInfo" class="object" style="width: 100px; height: 200px; background-color: red; display: none"></div>
<button type="button" onclick="hideShow()">click</button>
You're checking if (footer.style.display === "none") which is false accordingly to the HTML you provided as it contains the display: flex; property. Therefore, the else block of your conditional is executed.

I'm trying to create a feature using either jQuery or vanilla JS. My feature should be able to show/hide content on click. The initial task is easy enough and I'm able to show my hidden div using jQuery toggle, but I would also like to be able to switch my FA icon as well as the link text from 'Show content' to 'Hide content'.
Use
.toggleClass(`.fa-check .fa-cross')
add one as the default.
Toggle text can be handled by either not using .toggle (using .show/.hide) instead or by including a span for each text and toggling those. Or by having 2 buttons and toggling those.
Example snippet (needs fa icons)
$(".toggle").click(function() {
$(this).toggleClass("collapsed expanded")
$(this).find("i").toggleClass("fa-chevron-up fa-chevron-down")
});
.wrapper { border: 1px solid #CCC; width: 200px; }
.wrapper .details { border-top: 1px solid #CCC; }
.wrapper .toggle.collapsed > div.details { display:none; }
.wrapper .toggle.expanded > .more { display:none; }
.wrapper .toggle.collapsed > .less { display:none; }
<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script>
<div class='wrapper'>
<div class='toggle collapsed'><i class='fa fa-chevron-up'></i>
<div class='more'>more</div><div class='less'>less</div>
<div class='details'>details</div>
</div>
</div>
You can apply the same logic for the text to the icon as well if preferred (include 2 <i class='fa...) and then use css to show/hide them based on the class on the parent.
You can also add some css transition so it's less jumpy, or you can use $(this).find(".more,.less").slideToggle() instead of just toggle to add an effect.
There are dozens of ways to do it. Below is a step-by-step tutorial.
This should work, assuming you have already included jQuery.
<img id="imgtog" onclick="toggle()" src="someimg1.png">
<div id="content" hidden="">content</div>
<script>
var tog = false;
function toggle()
{
if(tog == false)
{
$('#content').removeAttr('hidden');
$('#imgtog').attr('src', 'otherimage2.png');
tog = true;
}
else
{
$('#content').attr('hidden', '');
$('#imgtog').attr('src', 'someimg1.png');
tog = false;
}
}
</script>

I'm trying to make a menu, but when I have tried to execute the code in Chrome I've got an error.
So for debug proposes I made a button:
<input type="button" style="position: fixed; left:0; bottom:0; width:50px; height:25px;" value="test" onclick="login('logf')" />
This is the function where error is:
var loginshow = false;
function login(c)
{
e = document.getElementsByClassName(c);
if(loginshow)
{
e.style.height = "0";
}
else
{
e.style.height = "110px";
}
loginshow=!loginshow;
}
The error from google chrome:
bar.js:13 Uncaught TypeError: Cannot set property 'height' of undefined
at login (bar.js:13)
at HTMLInputElement.onclick ((index):32)
getElementsByClassName returns an array-like object of all child elements which have all of the given class names. You need to iterate all the elements and apply the style on each one
var loginshow = false;
function login(c) {
let elements = document.getElementsByClassName(c);
for(let i=0,l=elements.length;i<l;i++){
elements[i].style.height = loginshow ? "0" : "110px";
}
loginshow = !loginshow;
}
div {
background-color: tomato;
border: 1px solid black;
}
<input type="button" style="position: fixed; left:0; bottom:0; width:50px; height:25px;" value="test" onclick="login('logf')" />
<div class="logf"></div>
<div class="logf"></div>

i'm looking for a script, wich changes the background image of an div container when spefic numbers are into the input field.
I build this creditcard layout here
inside of it is a <input type="text" name="" class="credit-input"> with the class credit-input.
What i'm looking for is, that if the first three numbers inside the value generate a different background.
So for example, when the value starts with 411, there should be a background image of an amex card, or when it starts with 311, there should be mastercards and so on.
there would be in total 4 different backgrounds.
i'm not so good in js, so i hope that i could find here some help from ya.
That's how my html looks at the moment.The class="jp-front" includes the whole style at the moment the
<div class="jp-front">
<input type="text" name="" class="credit-input">
</div>
thx for any help
Try this :
$(document).ready(function() {
$(".credit-input").on("input",function(){
var value = $(this).val();
if (value == "411")
$(".jp-front").css({backgroundImage:"url(http://www.lowestrates.ca/newcontent/img/creditcards/Gold_Rewards_Card_chip_467x293.png)"});
else if (value == "311")
$(".jp-front").css({backgroundImage:"url(https://www.bmo.com/img/main/credit-cards/large/rewards-card.jpg)"});
})
})
Final code :
$(document).ready(function() {
$(".credit-input").on("input",function(){
var value = $(this).val();
if (value == "411")
$(".jp-front").css({backgroundImage:"url(http://www.lowestrates.ca/newcontent/img/creditcards/Gold_Rewards_Card_chip_467x293.png)"});
else if (value == "311")
$(".jp-front").css({backgroundImage:"url(https://www.bmo.com/img/main/credit-cards/large/rewards-card.jpg)"});
})
})
.jp-front {
width: 300px;
height: 150px;
border: 1px solid #000;
background-size:100% 100%;
background-repeat: no-repeat;
padding: 20px 0px 0px 20px;
}
<div class="jp-front">
<input type="text" name="" class="credit-input">
</div>
<script src="https://ajax.googleapis.com/ajax/libs/jquery/1.12.4/jquery.min.js"></script>
Not overly complex, but this should do the trick:
$("input[name='card']").keyup( function() {
img = 'blank.png';
switch($(this).val().substring(0, 3)) {
case '111':
img = '111.png';
break;
case '222':
img = '222.png';
break;
}
$('.img').css('background', 'url(' + img + ') no-repeat center center');
});
Example: https://jsfiddle.net/6hhtgnep/
If you haven't JQuery
Add id="..." and onchange="" onkeypress="" onkeydown=""
<div class="jp-front" id="card-div-id">
<input id="card-input-field-id" type="text" name="" onchange="onCodeInput()" onkeypress="onCodeInput()" onkeydown="onCodeInput()" class="credit-input">
</div>
Javascript:
<script>
function onCodeInput(){
var card_number = document.getElementById('card-input-field-id').value;
if (str.substr(0, 4) == '5466') {
document.getElementById('card-div-id').style.backgroundImage="url(images/mastercard.jpg)"
} else { /* others */ }
}
</script>
Your input element will be -
<div class="jp-front">
<input type="text" name="card-number" class="credit-input">
</div>
Let your image element be
<img src="default.jpg" id="card-img">
Your JavaScript will be like this -
$('input[name=card-number]').keyup(function() {
var inp = $('input[name=search]').val();
if (inp === '311') {
$("#card-img").attr("src","mastercards.jpg");
}
else if (inp === '411') {
$("#card-img").attr("src","amex.jpg");
}
else if (inp === '') {
$("#card-img").attr("src","default.jpg");
}
});

JS code:
function showCaption() {
var captionVis = $('.grey-box-caption-text').css('display');
if(captionVis = "none") {
$('.grey-box-caption-text').width(0);
$(this).find('.grey-box-caption-text').show().animate({'width': '464px'},750);}
} else {
$(this).find('.grey-box-caption-text').animate({'width': '0'},750,
function(){$(this).hide();});
}
};
$('.caption-container').click(function() {
showCaption();
return false;
}
);
HTML code:
<div class="one-half column home-three-img">
<div class="caption-container">
<div class="grey-box-caption">
</div>
<div class="grey-box-caption-text">This is a caption test - Hopefully this works
</div>
</div>
<img src="images/3.jpg">
</div>
This won't work and I'm a JS noob. Please help.
I'm trying to get the caption section to slide out from the left to the right. When i click on the parent container nothing happens. I'm expecting the caption to shoot out and hide when I click again.
I have Jquery loaded properly and have a document.ready function that works.
Link to the WIP http://clients.pivotdesign.com/dev/annual_report_2014/index.html
A big problem is that the value of this won't be set in your "showCaption" function. Add a return false; to the end of that function:
function showCaption(){
var captionVis = $('.grey-box-caption-text').css('display');
if (captionVis == "none") {
$('.grey-box-caption-text').width(0);
$(this).find('.grey-box-caption-text').show().animate({'width': '464px'},750);
}
else {
$(this).find('.grey-box-caption-text').animate({'width': '0'},750, function(){
$(this).hide();
});
}
};
and then change the handler assignment to:
$('.caption-container').click(showCaption);
Also note that your test in that if statement was incorrect: use == or === for comparison.
I modified the CodePen from Pointy a bit and it should do the same with less code.
Why the gray box increases the height here in the SO demo, I don't know. In this CodePen it works with-out this "bug".
function showCaption() {
var $graybox = $('.grey-box-caption-text');
$graybox.animate({
width: 'toggle',
opacity: 'toggle'
}, 'slow');
};
$(function(){
$("#wrapper").on("click", showCaption);
});
.grey-box-caption {
min-height: 3em;
min-width: 20px;
background-color: #bbb;
display: inline-block;
}
.grey-box-caption-text {
display: none;
padding: 1em;
font-family: sans-serif;
white-space: nowrap;
overflow: hidden;
}
<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script>

i have a simple sms interface written in javascript and every time i click on a call button, a calling bar will(something like a progress bar that never stops or status bar). i still have no code for it because im still a beginner..please help

if(some conditon)

// nothing, this else not required

Warning: The following answer contains jQuery
So what you need to do is make two images, a foreground image to set the style:
(Can't see it very well, put it on a black background)
And a background image to create an animation effect:
Next, you must superimpose the FG on the BG.
HTML:
<div class="callbar">
<div class="callbarbg" style="width: 200px;"></div>
<div class="callbarfg"></div> <!-- later elements have higher z-index -->
</div>
CSS:
.callbarbg {
height: 20px;
background-repeat: repeat-x;
background-image: url("http://s9.postimage.org/4oij09p7j/sliding_Progress_Bar_BG.png");
background-position:right top;
}
.callbarfg {
position:relative;
top:-20px;
width: 200px;
height: 20px;
background-image: url("http://s9.postimage.org/bg8y34e73/sliding_Progress_Bar_FG.png");
}
.callbar {
overflow:hidden;
width:200px;
height:20px;
}
Finally, you must move the background image in order to make the fade in/out animation in each dot:
JS:
window.setInterval(function(){
var obj = $("parent of .callbar").find(".callbarbg");
if(!obj.data("width"))
obj.data("width", 200);
var w = obj.data("width") + 3;
obj.data("width", w).css("width", w);
var h = w%200;
if(h == 0 || h == 1 || h == 2){
obj.data("width", 200);
}
}, 33);
