I hace some code that adds dynamic input boxes on a click. In all of the major browsers, it works fine. But in IE8 it does nothing. There are no errors being reported and developer tools shows no errors either. should this code work with IE8. Thanks

I am trying to hide a placeholder while the input is being used and while there's text inside the input. Here's a simplified version of the HTML for the input and placeholder:
<div id="search-placeholder"><span class="fa fa-search"></span> Search</div>
<input id="search-input" type="text" name="search" />
I tried using jQuery but it does not return the desired result:
$(document).ready(function(){
$('#search-input').focus(function(){
$('#search-placeholder').fadeOut(100);
}).focusout(function(){
$('#search-placeholder').fadeIn(100);
});
});
The placeholder will hide when the input is selected, as it should. But it will show again when the user clicks elsewhere, even while the input is not empty! The placeholder is visible on top of the input value, so I tried a different approach:
$('#search-input').change(function(){
if($('#search-input').val() = '') {
$('#search-placeholder').fadeIn(100);
}else{
$('#search-placeholder').fadeOut(100);
}
})
Unfortunately, this only works when the user clicks elsewhere. The placeholder still shows while typing and while the input is selected, again showing itself on top of the input value. How do I hide <div id="search-placeholder"> while <div id="search-input"> is not empty, or when the input is selected by clicking or tapping it (on focus)?
Maybe try to check the value of the input in the focusout event and only show the placeholder if it's empty:
$(document).ready(function(){
$('#search-input').focus(function(){
$('#search-placeholder').fadeOut(100);
}).focusout(function(){
if($('#search-input').val() === '')
{
$('#search-placeholder').fadeIn(100);
}
});
});
I think you could extract the $('#search-input') and $('#search-placeholder') elements to variables, so the code becomes a bit more readable.
You do this using javascript and jquery
jquery :-
$(document).ready(function(){
$('#search-input').focus(function() {
$('#search-placeholder').fadeOut(100);
});
$('#search-input').focusout(function() {
if($('#search-input').val() === '') {
$('#search-placeholder').fadeIn(100);
}
});
});
javascript
var searchInput = document.getElementById("search-input");
var searchPlaceholder = document.getElementById("search-placeholder");
searchInput.onfocus = function() {
searchPlaceholder.style.display = "none";
}
searchInput.onfocusout = function() {
if(this.value == "") {
searchPlaceholder.style.display = "block";
}
}
if you want to add fade-in fade-out transitions in javascript method use css transition property- transition: opacity 1s and instead of changing style.display change style.opacity to 1(show) and 0(hide)
I would like to have two buttons which are basically categories. Let's name them category A and category B. The are displayed left and right. Below i would like to display some text which is dependent of the chosen category (i.e the clicked button) so that category A shows text A and category B shows text B.
This if for html. I'm working on a wordpress homepage.
I was able to install one button which toggles text (basically button 1 = Category A). But i couldn't manage to insert a second button (basically button 2 = Category B). Any ideas? Highly appreciated!
<!DOCTYPE html>
<html>
<head>
<meta name="viewport" content="width=device-width, initial-scale=1">
</head>
<body>
<p>Click the button to swap the text of the DIV element:</p>
<p><button onclick="myFunction()">Click Me</button></p>
<div id="myDIV">Hello</div>
<script>
function myFunction() {
var x = document.getElementById("myDIV");
if (x.innerHTML === "Hello") {
x.innerHTML = "Swapped text!";
} else {
x.innerHTML = "Hello";
}
}
</script>
</body>
</html>
I expect to have 2 buttons which display 2 categories, the text should toggle according to which button has been clicked.
Could put the description in an attribute, then get the attributes value on click and change the html of the description. Here is a jsFiddle
<div>
<button class="js-button default-button" data-description="Category A's Description" onclick="myFunction(this)">
Category A
</button>
<button class="js-button default-button" data-description="Category B's Description" onclick="myFunction(this)">
Category B
</button>
</div>
<div id="js-description" class="description">
</div>
<script>
function myFunction(elem) {
var x = document.getElementById("js-description");
var description = elem.getAttribute('data-description');
x.innerHTML = description;
var button = document.getElementsByClassName('js-button');
for (var i = 0; i < button.length; i++) {
button[i].classList.remove('active-button');
}
elem.classList.add('active-button');
}
</script>
<style>
.default-button{
font-size:16px;
border-radius: 4px;
padding:7px 12px;
}
.active-button{
background:blue;
color:#fff;
}
.description{
margin-top:20px;
}
</style>
I don't really like all these solutions because everything is written from JS but contents probably come from database. So here is my solution :
// Native JS version
// Working Fiddle : https://jsfiddle.net/d34cbtw7/
var togglers = document.querySelectorAll('[data-toggle="tab"]');
for (var i = 0; i < togglers.length; i++) {
togglers[i].addEventListener('click', function() {
var tabs = document.querySelectorAll('.tab');
for(var j = 0; j < tabs.length; j++) {
tabs[j].classList.remove('active');
}
var $target = document.querySelector(this.getAttribute('data-target'));
$target.classList.add('active');
});
}
// jQuery version
$('body').on('click', '[data-toggle="tab"]', function(e) {
e.preventDefault();
// Select our target
var $target = $($(this).data('target'));
// Hide all tabs
$('.tab-contents .tab').removeClass('active');
// Show only $target tab
$target.addClass('active');
});
.tab-contents .tab {
display: none;
}
.tab-contents .tab.active {
display: block;
}
<script src="https://cdnjs.cloudflare.com/ajax/libs/jquery/3.3.1/jquery.min.js"></script>
<button data-toggle="tab" data-target="#cat-A-content">
Cat A
</button>
<button data-toggle="tab" data-target="#cat-B-content">
Cat B
</button>
<div class="tab-contents">
<div class="tab active" id="cat-A-content">
My category A contents
</div>
<div class="tab" id="cat-B-content">
My category B contents
</div>
</div>
I also don't really like "onclick" attribute in HTML...
I've made a quick codepen as example.
You can achieve this by passing a parameter to the onClick function. In this example I keep track of the last button clicked, and the text it should render. If the last button clicked was the same button, the switched back to default. I hope this helps.
https://codepen.io/maffekill/pen/rbpjzw
HTML
<p>Click the button to swap the text of the DIV element:</p>
<p><button onclick="myFunction(1, 'TEXT A')">TEXT A</button></p>
<p><button onclick="myFunction(2, 'TEXT B')">TEXT B</button></p>
<div id="myDIV">Default Text</div>
JS
// Keep track of the button currently clicked
var activeBtn = null;
function myFunction(btnId, text) {
var x = document.getElementById("myDIV");
// If the last button is the same as the new one, show default text
if (activeBtn === btnId) {
x.innerHTML = "Default Text";
activeBtn = null
} else {
// Else show the text given to the text param
x.innerHTML = text;
activeBtn = btnId;
}
}
There are multiple ways to achieve this, but the easiest way I could come up with to explain this to you would be as following:
function myFunction(myEle) {
var x = document.getElementById("myDIV");
x.innerHTML = "This is category " + myEle.value;
}
<p>Click the button to swap the text of the DIV element:</p>
<p>
<button onclick="myFunction(this)" value="a">
Category A
</button>
<button onclick="myFunction(this)" value="b">
Category B
</button>
</p>
<div id="myDIV">Hello</div>
JSFiddle
No need to overcomplicate things.
Firstly you would like to send the clicked element from the caller (which in this case would be the clicked element as well, the <button> element). You could use JavaScript's thisfor this purpose.
Within your function you can name a parameter between parenthesis, so in my example above: function myFunction() contains a parameter called myEle so it will look like: function myFunction(myEle). Once the function will be triggered, the parameter called myEle will be set to the clicked element (or
JavaScript's this). You can simply access any of its attributes like value by using a dot: myEle.value.
Knowing the above, you could apply it to whatever you require your function to do (refer to my example code above).
Currently on button click, I'm able to display the user input from inside the textbox, but it's displayed inside the same Div every time.
Textbox and the button (HTML file)-
<input type="text" name="inputText"><br>
<tr>
<input type="button" value="ADD" ng-click="$ctrl.addtext()">
</tr>
<div id="outputDiv"></div>
JS function-
ctrl.addtext = function () {
var div = document.getElementById('outputDiv');
div.innerHTML += newtext+"\n";
}
How can I get the user input in a different Div and a newline every time?
EDIT: A similar question has been asked for JQuery and it's JS is-
$('#submit').click(function() {
var text = $('#input').val();
$('#newDivs').append('<div>' + text + '</div>');
});
How can I do that append in Angular?
Got it to work using this in the JS function-
div.innerHTML += "<div>"+newtext+"</div>\n";
Instead of-
div.innerHTML += newtext+"\n";

I am trying to get some knowledge in html and canvases, and i am stuck with a little problem. My canvas has a circle on top and 2 buttons below it. One button can be clicked whereas the other is an input button. What I have to do is that i should be able to type in the second button and when the first button is clicked, the first button's value should be changed to the value typed in second button. That click should also move the circle in x axis. I did the movement part, can anyone help me out with the input buttons inside the canvas?
Here's the part of my code, here i tried to put buttons outside the canvas, but i need them in the canvas, not as the html buttons though:
<script>
var stage;
function init() {
stage = new createjs.Stage("myCanvas");
var cbgColor = new createjs.Shape();
cbgColor.graphics.beginFill("#000000").drawRect(0,0, stage.canvas.height,stage.canvas.width);
stage.addChild(cbgColor);
var ball = new createjs.Shape();
ball.graphics.beginFill("#ff0000").drawCircle(0,0,50);
ball.x=100;
ball.y=200;
stage.addChild(ball);
createjs.Ticker.addEventListener("tick",tick);
createjs.Tween.get(ball,{loop:false}).to({x:650}, 3000).to({x:100},1);
}
function tick(event){
stage.update();
}
function handleClick(event){
console.log("clicked");
}
</script>
</head>
<body bgcolor="black" onload="init()">
<canvas id="myCanvas" height=300 width=600>
</canvas><br>
<script>
function change()
{
var inp = document.getElementById('ip').value;
document.getElementById('add').value = inp;
console.log("clicked");
document.getElementById('ip').value=null;
}
</script>
<input id="add" value="Go!" type="button" onclick="change();init();" style="background-color:yellow;font-size:30px;width:110px;height:40px;margin-left:250px"><br>
<br><input type="text" id="ip" style="background-color:black;color:white;font-size:30px;width:140px;height:40px;margin-left:230px">
i have built a multi step form that works , but it is not very "elegant" coded,
so i am asking
for your advice to make it more efficient ,
i have placed here only 2 steps out of 3 because the first step - email name etc', is not relevant for my question:
in each step 2 and 3 there are 2 styled radio button yes and no for the user to select,
in each step i need to toggle between check and uncheck styled images and of course prevnt that both
yes and no check images will show at the same time.
i know that the default/not styled radio buttons behavior prevents two checked buttons at the same time- can i use it here to save some lines of code?

Dude my wish to you take a look on good js library - knockout to represants all that kind show, hide functunality and forms inputs, checkbox, radiobutton modifications.
If you're using images to style your radiobuttons I would suggest combining the images into a Sprite and just using css to move the background-position of the image using the input[type=radio]:checked selector. No javascript necessary.
For Example - you combine your two images into a single image that is 100px wide, each individual image being 50px wide. And then style the checkbox...
input[type=radio].myCustomRadioButton {
background: url(myRadioButtonSprite.png) 0 0;
}
input[type=radio].myCustomRadioButton:checked {
background-position: -50px 0;
}
Assuming your images are lined up horizontally in your sprite, this would move the background image of the radiobutton left 50px to display the checked-image, when the radiobutton is checked.
As a side note, doing this is going to require unsetting some of the browser styling that is going to occur automatically. A good reset for form elements is to start with these styles.
-webkit-appearance: none;
-moz-appearance: none;
appearance: none;
Keep in mind if you need to support Internet Explorer versions less than 9, the :checked pseudo-selector isn't available in pure CSS and you may need to resort to some scripting.
Listen for the change event on your custom radio buttons and update a parent element based on that.
Here's an example.
The <input> has position: absolute so the clip property can be applied to hide it and it does not affect the content box of its parent, which has relative position to contain it.
I used background-color but you could swap this in for your image urls or change the background-position of a sprite as suggested in rob-gordon's answer.
You can still add visible label text inside the label as you see in the second set of radio inputs.
