javascript expand/collapse text - collapse on default

I'm very inexperienced in javascript but have managed (with the help of google) to put together the following expandable/collapsible link
<script type="text/javascript">
function toggleMe(a) {
var e = document.getElementById(a);
if(!e) return true;
if(e.style.display == "none") {
e.style.display = "block"
}
else {
e.style.display = "none"
}
return true;
}
</script>
<p>
<input onclick="return toggleMe('para1')" style="font-size:18px; color:#008080;" type="text" value="LINK TO EXPAND" />
</p>
<p id="para1">
<strong><em>text text text text</em></strong>
</p>
The only problem with it is that it is expanded by default and I wanted it collapsed by default. Can anyone help with this? Thank you!
Also, if anyone knows how to get +/- signs next to the link that change depending on whether it is expanded or collapsed, that would be great.

<script type="text/javascript">
function toggleMe(a) {
var e = document.getElementById(a);
var toggleIcon = document.getElementById('toggle-icon');
if(!e) return true;
if(e.style.display == "none") {
e.style.display = "block";
toggleIcon.innerHTML = '-';
}
else {
e.style.display = "none";
toggleIcon.innerHTML = '+';
}
return true;
}
</script>
<p>
<input onclick="return toggleMe('para1')" style="font-size:18px; color:#008080;" type="text" value="LINK TO EXPAND" />
<span id="toggle-icon">+</span>
</p>
<p id="para1" style="display: none;">
<strong><em>text text text text</em></strong>
</p>

You can try putting in style statement the display option like below:
<p id="para1" style="display:none"><strong><em>text text text text</em></strong></p>
That can default collapse when you open your html, hope it help you...

Options 1:
Add this to your css to hide it by default:
#para1 {
display: none;
}
Options 2:
Move your script down, and call it initially toggleMe('para1'); so you will hide it first.
<p>
<input onclick="return toggleMe('para1')" style="font-size:18px; color:#008080;" type="text" value="LINK TO EXPAND" />
</p>
<p id="para1">
<strong><em>text text text text</em></strong>
</p>
<script type="text/javascript">
function toggleMe(a) {
var e = document.getElementById(a);
if(!e) return true;
if(e.style.display == "none") {
e.style.display = "block"
}
else {
e.style.display = "none"
}
return true;
}
toggleMe('para1');
</script>

Daniel has the correct answer to your question. This is a bit more than you asked for, but I think you will have a better time if you manipulate classes instead of element styles properties. Just makes it a bit more flexible.
In the example below I wrapped your code in a common element and then changed that element's class to achieve your desired effect. That let me easily add in your plus and minus too.
It's a little raw but you can see where this can take you. Hope it helps.
https://jsfiddle.net/6xoe1b94/
function toggleMe(a) {
var e = document.getElementById('wrapper');
if(! e.classList.contains('active')) {
e.classList.add('active');
}
else {
e.classList.remove('active');
}
}
#para1{
display:none;
}
.active #para1{
display:block;
}
#plus{
display:inline-block;
}
#minus{
display:none;
}
.active #plus{
display:none;
}
.active #minus{
display:inline-block;
}
<div id='wrapper'>
<p>
<input onclick="return toggleMe('para1')" style="font-size:18px; color:#008080;" type="text" value="LINK TO EXPAND" /><span id='plus'>+</span><span id='minus'>-</span>
</p>
<p id="para1">
<strong><em>text text text text</em></strong>
</p>
</div>

I added a solution that removes the javascript and css from your html. I also changed your expand/collapse element to a div instead of input. I've added a span element within the div that changes it's text content (either + or -) based on whether #para1 is displayed or not. Also, in css I added display: none; to #para1 (this initially hides the element), cursor: pointer; (shows it is clickable when the user hovers over it) user-select: none; (stop div from highlighting when user clicks on it).
// store elements
var expandEl = document.getElementById("expand");
var plusMinusEl = document.getElementById("plusMinus");
var para1El = document.getElementById("para1");
// toggle function: pass element as argument
function toggleMe(el) {
// check if element is hidden
if(el.offsetParent === null) {
plusMinusEl.textContent = "-";
el.style.display = "block"
}
else {
plusMinusEl.textContent = "+";
el.style.display = "none"
}
}
// click function for expand div
expandEl.addEventListener("click", function() {toggleMe(para1El)});
#expand {
font-size:18px;
color:#008080;
cursor: pointer;
user-select: none; /* stop div from highlighting */
}
#para1 {
display: none;
}
<div id="expand">
LINK TO EXPAND <span id="plusMinus">+</span>
</div>
<p id="para1"><strong><em>text text text text</em></strong></p>

Click on edit jquery

I am a newbie so my question is pretty simple and straight forward.
I have a simple html text. When I click on that html text, the text should change to input field with the value retained and when the user clicks outside the text box, the input text field now should change to html text.
<div class="myText"> Hellow World </div>
Can somebody do this in jquery/Meteor. I am actually building a meteor project

You can do that with the contenteditable attribute
<div class="myText" contenteditable="true"> Hellow World </div>
<!-- Your div is now editable -->

Updated DEMO jsFiddle
$(document).ready(function() {
$('.editable').on('click', function() {
var that = $(this);
if (that.find('input').length > 0) {
return;
}
var currentText = that.text();
var $input = $('<input>').val(currentText)
.css({
'position': 'absolute',
top: '0px',
left: '0px',
width: that.width(),
height: that.height(),
opacity: 0.9,
padding: '10px'
});
$(this).append($input);
// Handle outside click
$(document).click(function(event) {
if(!$(event.target).closest('.editable').length) {
if ($input.val()) {
that.text($input.val());
}
that.find('input').remove();
}
});
});
});
In my solution you need to add class="editable" to all editable divs.
You also need to set position: relative to these divs. May be you can update my code and edit the css:
.editable {
position: relative;
}
To correctly align the input inside the div, you need to remove the border or set the .css({}) of the input to left: -1px and top: -1px. The border actually pushes the input 1px left and 1px form the top.

Try this:
$(function() {
$('div.myText').on('click', function() {
var div = $(this);
var tb = div.find('input:text');//get textbox, if exist
if (tb.length) {//text box already exist
div.text(tb.val());//remove text box & put its current value as text to the div
} else {
tb = $('<input>').prop({
'type': 'text',
'value': div.text()//set text box value from div current text
});
div.empty().append(tb);//add new text box
tb.focus();//put text box on focus
}
});
});
<script src="https://ajax.googleapis.com/ajax/libs/jquery/1.9.1/jquery.min.js"></script>
<div class="myText">Hello world</div>
<div class="myText">This is second</div>

Try this:
$(document).click(function() {
$('.myText').html("Hello World");
});
$(".myText").click(function(event) {
$('.myText').html("<input type='text' id='test' value='Hello World'/>");
$('#test').focus();
event.stopPropagation();
});
FIDDLE.

To do it very easily and understandable you can also make two elements instead of changing.
Working fiddle: http://jsfiddle.net/45utpzhx/
It does an onClick event and onBlur.
html
<div>
<span class="myText">Hello World</span>
<input class="myInput" />
</div>
jQuery
$(document).ready(function() {
$(".myText").click(function() {
$(this).hide();
var t = $('.myText').html();
$('.myInput').val(t);
$('.myInput').show();
});
$(".myInput").blur(function() {
$(this).hide();
var t = $('.myInput').val();
$('.myText').html(t);
$('.myText').show();
});
});

Replace the clicked element with an input with value equal to the clicked element's text
$(document).on('click', '.myText', function() {
var that = $(this);
var text = that.text();
that.wrap('<div id="wrp" />');
$('#wrp').html('<input type="text" value="' + text + '" />');
});
<script src="https://ajax.googleapis.com/ajax/libs/jquery/1.11.1/jquery.min.js"></script>
<div class="myText"> Hellow World </div>

You can try this solution :
$('.myText').click(function(){
var m = $(this).text();
$(this).html('');
$('<input/>',{
value : m
}).appendTo(this).focus();
});
$(document).on('blur','input',function(){
var m = $(this).val();
$(this).parent().find('input').remove().end().html(m);
});
working DEMO

$('#text').on('click', function() {
$("#text").hide();
if ($("#text").text()=="Add New text"){
$('#in_text').val("");
}else{
$('#in_text').val($("#text").text());
}
$("#in_text").show();
});
// Handle outside click
$(document).click(function(event) {
if(!$(event.target).closest('.editable').length) {
if($("#text").css('display') == 'none'){
$("#in_text").hide();
if ($("#in_text").val()=="" ){
$('#text').text("Add New text");
$('#text').addClass("asd");
}else{
$('#text').removeClass("asd");
$('#text').text($("#in_text").val());
}
$("#text").show();
}
}
});
#in_text{
display:none;
}
.editable{
width:50%;
}
.asd{
border-bottom : 1px dashed #333;

<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script>
<div class="editable">

<input type="text" placeholder="Add New Text" id="in_text"/></div>

show more/Less text with just HTML and JavaScript

I am needing to create a show more/less text function, but with just JavaScript and HTML.. I can't use any additional libraries such as jQuery and it can't be done with CSS. The sample code I have added displays the 'more' text, but not the 'less'.
If someone could point me in the right direction, it would be much appreciated.
I've spent the majority of the day frying my brain over this, as its clearly not the modern way to do it, however, my HTML is:
<html>
<head>
<script type="text/javascript" src="moreless.js"></script>
</head>
<body>
Lorem ipsum dolor sit amet
<p>
<p id="textarea"><!-- This is where I want to additional text--></div>
</p>
<a onclick="showtext('text')" href="javascript:void(0);">See More</a>
<p>
Here is some more text
</body>
</html>
and my JavaScript is (moreless.js):
function showtext()
{
var text="Here is some text that I want added to the HTML file";
document.getElementById("textarea").innerHTML=text;
}

My answer is similar but different, there are a few ways to achieve toggling effect. I guess it depends on your circumstance. This may not be the best way for you in the end.
The missing piece you've been looking for is to create an if statement. This allows for you to toggle your text.
More on if statements here.
JSFiddle: http://jsfiddle.net/8u2jF/
Javascript:
var status = "less";
function toggleText()
{
var text="Here is some text that I want added to the HTML file";
if (status == "less") {
document.getElementById("textArea").innerHTML=text;
document.getElementById("toggleButton").innerText = "See Less";
status = "more";
} else if (status == "more") {
document.getElementById("textArea").innerHTML = "";
document.getElementById("toggleButton").innerText = "See More";
status = "less"
}
}

With some HTML changes, you can absolutely achieve this with CSS:
Lorem ipsum dolor sit amet
<p id="textarea">
<!-- This is where I want to additional text-->
All that delicious text is in here!
</p>
<!-- the show/hide controls inside of the following
list, for ease of selecting with CSS -->
<ul class="controls">
<li class="show">Show</li>
<li class="hide">Hide</li>
</ul>
<p>Here is some more text</p>
Coupled with the CSS:
#textarea {
display: none; /* hidden by default */
}
#textarea:target {
display: block; /* shown when a link targeting this id is clicked */
}
#textarea + ul.controls {
list-style-type: none; /* aesthetics only, adjust to taste, irrelevant to demo */
}
/* hiding the hide link when the #textarea is not targeted,
hiding the show link when it is selected: */
#textarea + ul.controls .hide,
#textarea:target + ul.controls .show {
display: none;
}
/* Showing the hide link when the #textarea is targeted,
showing the show link when it's not: */
#textarea:target + ul.controls .hide,
#textarea + ul.controls .show {
display: inline-block;
}
JS Fiddle demo.
Or, you could use a label and an input of type="checkbox":
Lorem ipsum dolor sit amet
<input id="textAreaToggle" type="checkbox" />
<p id="textarea">
<!-- This is where I want to additional text-->
All that delicious text is in here!
</p>
<label for="textAreaToggle">textarea</label>
<p>Here is some more text</p>
With the CSS:
#textarea {
/* hide by default: */
display: none;
}
/* when the checkbox is checked, show the neighbouring #textarea element: */
#textAreaToggle:checked + #textarea {
display: block;
}
/* position the checkbox off-screen: */
input[type="checkbox"] {
position: absolute;
left: -1000px;
}
/* Aesthetics only, adjust to taste: */
label {
display: block;
}
/* when the checkbox is unchecked (its default state) show the text
'Show ' in the label element: */
#textAreaToggle + #textarea + label::before {
content: 'Show ';
}
/* when the checkbox is checked 'Hide ' in the label element; the
general-sibling combinator '~' is required for a bug in Chrome: */
#textAreaToggle:checked ~ #textarea + label::before {
content: 'Hide ';
}
JS Fiddle demo.

Try to toggle height.
function toggleTextArea()
{
var limitedHeight = '40px';
var targetEle = document.getElementById("textarea");
targetEle.style.height = (targetEle.style.height === '') ? limitedHeight : '';
}

This is my pure HTML & Javascript solution:
var setHeight = function (element, height) {
if (!element) {;
return false;
}
else {
var elementHeight = parseInt(window.getComputedStyle(element, null).height, 10),
toggleButton = document.createElement('a'),
text = document.createTextNode('...Show more'),
parent = element.parentNode;
toggleButton.src = '#';
toggleButton.className = 'show-more';
toggleButton.style.float = 'right';
toggleButton.style.paddingRight = '15px';
toggleButton.appendChild(text);
parent.insertBefore(toggleButton, element.nextSibling);
element.setAttribute('data-fullheight', elementHeight);
element.style.height = height;
return toggleButton;
}
}
var toggleHeight = function (element, height) {
if (!element) {
return false;
}
else {
var full = element.getAttribute('data-fullheight'),
currentElementHeight = parseInt(element.style.height, 10);
element.style.height = full == currentElementHeight ? height : full + 'px';
}
}
var toggleText = function (element) {
if (!element) {
return false;
}
else {
var text = element.firstChild.nodeValue;
element.firstChild.nodeValue = text == '...Show more' ? '...Show less' : '...Show more';
}
}
var applyToggle = function(elementHeight){
'use strict';
return function(){
toggleHeight(this.previousElementSibling, elementHeight);
toggleText(this);
}
}
var modifyDomElements = function(className, elementHeight){
var elements = document.getElementsByClassName(className);
var toggleButtonsArray = [];
for (var index = 0, arrayLength = elements.length; index < arrayLength; index++) {
var currentElement = elements[index];
var toggleButton = setHeight(currentElement, elementHeight);
toggleButtonsArray.push(toggleButton);
}
for (var index=0, arrayLength=toggleButtonsArray.length; index<arrayLength; index++){
toggleButtonsArray[index].onclick = applyToggle(elementHeight);
}
}
You can then call modifyDomElements function to apply text shortening on all the elements that have shorten-text class name. For that you would need to specify the class name and the height that you would want your elements to be shortened to:
modifyDomElements('shorten-text','50px');
Lastly, in your your html, just set the class name on the element you would want your text to get shorten:
<div class="shorten-text">Your long text goes here...</div>

I hope this helps you. Here is the functionality:
When text characters is less than or equal to 12. Then it displays the whole text and also does not display the more/less button
When text characters is more than 12. Displays only 12 characters of the text and also a More button which when pressed, shows the whole text.
When the More button is pressed the button changes to Less

var startStatus = "less";
function toggleText() {
var text = "Here is the text that I want to play around with";
if (text.length > 12) {
if (startStatus == "less") {
document.getElementById("textArea").innerHTML = `${text.substring(0, 12)}...`;
document.getElementById("more|less").innerText = "More";
startStatus = "more";
} else if (startStatus == "more") {
document.getElementById("textArea").innerHTML = text;
document.getElementById("more|less").innerText = "Less";
startStatus = "less";
}
} else {
document.getElementById("textArea").innerHTML = text;
}
}
toggleText();

I'm not an expert, but I did a lot of looking to implement this for myself. I found something different, but modified it to accomplish this. It's really quite simple:
The function takes two arguments, a div containing only the words "show more" [or whatever] and a div containing the originally hidden text and the words "show less." The function displays the one div and hides the other.
NOTE: If more than one show/hide on page, assign different ids to divs
Colors can be changed
<p>Here is text that is originally displayed</p>
<div id="div1">
<p style="color:red;" onclick="showFunction('div2','div1')">show more</p></div>
<div id="div2" style="display:none">
<p>Put expanded text here</p>
<p style="color:red;" onclick="showFunction('div1','div2')">show less</p></div>
<p>more text</p>
Here is the Script:
<script>
function showFunction(diva, divb) {
var x = document.getElementById(diva);
var y = document.getElementById(divb);
x.style.display = 'block';
y.style.display = 'none';
}
</script>

You can also use details HTML tag which does the work for you.

How to get the object reference of a HTML element for jQuery use?

A div container open nicely to fit the overflow content.
It works.
But how do I connect the reference of the triggered HTML element with jQuery.
There should be a better way than this $("#"+divId)
I got this code:
$('.text').mouseenter(function() {
//var $id = $(this); ?
//var $id = document.getElementById(divId); ?
var divId = this.id;
var $id = $("#"+divId);
var overflow = $id.prop("scrollHeight");
this.divHeight = $id.height();
$id.animate({height:overflow},1000);
});
.text{
color: #000000;
background-color: #ffffff;
overflow: hidden;
height: 100px;
position: relativ;}
<div class="text" id="text1">
<content>
</div>
<div class="text" id="text2">
<content>
</div>
<div class="text" id="text3">
<content>
</div>
PS Why is $(this).height() working but this is not $(this).prop("scrollHeight") ?
Thanks for help understanding.

try something like this
CHANGE THIS
var divId = this.id;
var $id = $("#"+divId);
TO
var $id = $(this);

Use jquery method like this
$(this).prop("scrollHeight");

when double-clicking one element, another gets selected

I've written an image scroller in html/css/js, a very simple one: right button is clicked, I go through all images inside "holder"-div and change the class of the image after the one with classname="current".
But that's not where the problem lies, I think. Whenever I successively click on the left or the right button, the image in the div gets selected (blue selection box). If I successively click the left button, even the text above it gets selected.
<div class="grid_4 omega image_box">
<div id="txt_choose" class="image_txt">
this is helpful text
</div>
<div id="alt_spacer"></div>
<div id="image_content" class="image_content" onclick="chooseImageType(this)">
<div id="current" class="current"><img src="images/default1.png" /></div>
<div id="current" class="hidden"><img src="images/default2.png" /></div>
</div>
<!--- left button --->
<div class="image_btn_left" onclick="showPrev()"></div>
<!--- right button --->
<div class="image_btn_right" onclick="showNext()"></div>
</div>
and this is the css:
.image_btn_right
{
width : 20px;
height : 20px;
position : relative;
float : left;
margin-top : -170px;
margin-left : 260px;
z-index : 4;
cursor : pointer;
background-image: url('../images/right.png');
}
.image_btn_left
{
width : 20px;
height : 20px;
position : relative;
float : left;
margin-top : -170px;
margin-left : 20px;
z-index : 4;
cursor : pointer;
background-image: url('../images/left.png');
}
.image_content
{
height : 280px;
background-color: white;
margin : 10px;
}
on request, my javascript:
function showNext()
{
//vars
var shown = false;
var current;
$('#image_content > div').each(function()
{
if($(this).attr('class') == "current")
{
current = $(this);
shown = true;
}
else if($(this).attr('class') == "hidden" && shown == true)
{
current.hide();
current.attr('class', 'prev');
current.attr('id', '');
$(this).show();
$(this).attr('class', 'current');
$(this).attr('id', 'current');
shown = false;
}

Is there anyway to stop the image and the text above to be selected like that (without actually making them not selectable)?
Could it be because of the relative position of the buttons and their z-index..?

This works in your JS fiddle.
function showNext()
{
//vars
var shown = false;
var current;
window.getSelection().removeAllRanges();
$('#image_content > div').each(function()
{
if($(this).attr('class') == "current")
{
current = $(this);
shown = true;
}
else if($(this).attr('class') == "hidden" && shown == true)
{
current.hide();
current.attr('class', 'prev');
current.attr('id', '');
$(this).show();
$(this).attr('class', 'current');
$(this).attr('id', 'current');
shown = false;
}
});
}
function showPrev()
{
window.getSelection().removeAllRanges();
//vars
var prev_present = false;
var prev;
$('#image_content > div').each(function()
{
if($(this).attr('class') == "prev")
{
prev = $(this);
prev_present = true;
}
else if($(this).attr('class') == "current" && prev_present == true)
{
$(this).hide();
$(this).attr('class', 'hidden');
$(this).attr('id', '');
prev.show();
prev.attr('class', 'current');
prev.attr('id', 'current');
prev_present = false;
}
});
}

I found the answer and it was painfully easy.. >_>
I just needed to wrap the buttons in another div, so they became more eperated from the rest of the html.
Like so:
<div>
<!--- left button --->
<div class="image_btn_left" onclick="showPrev()"></div>
<!--- right button --->
<div class="image_btn_right" onclick="showNext()"></div>
</div>
