Make a div clickable and copyable? - javascript

As stated in the question, I have a div that I want to make clickable and copy-able?
to make the div copy-able, I simply do as following
<a href="/example.com">
<div class="div">i contain some text</div>
</a>
But when trying to copy the text in that are inside of the div, the link gets clicked. What I want to do is that when clicking on the div, it should go to the url and that works. But I want also to make it possible to copy the text that is inside of the clickable div.
I prefer to fix the problem with html & css but even javascript is acceptable as last last resort.

This requires javascript, and we need 3 events to identify if the user is copying the text. Check out the snippet below, Let me know if it helps.
class Box {
constructor(target) {
this.isUserCoping = false;
this.isMouseClicked = false;
this.handleMouseDown = this.handleMouseDown.bind(this)
this.handleMouseMove = this.handleMouseMove.bind(this)
this.handleMouseUp = this.handleMouseUp.bind(this)
let $target = document.querySelector(target);
$target.addEventListener('mousedown', this.handleMouseDown),
$target.addEventListener('mousemove', this.handleMouseMove),
$target.addEventListener('mouseup', this.handleMouseUp);
}
handleMouseDown() {
this.isMouseClicked = true;
}
handleMouseMove() {
this.isMouseClicked && (this.isUserCoping = true);
this.isMouseClicked = false;
}
handleMouseUp(e) {
!this.isUserCoping && this.navigate(e.target.dataset.href)
console.log(this.isUserCoping);
this.isUserCoping = false;
console.log(this.isUserCoping);
}
navigate(href) {
window.location.href = href;
}
}
new Box('.js-div');
<div class="js-div" data-href='https://www.google.com'>i contain some text</div>

add following:
.div{
display:inline-block
}

How to create curriculum presentation for a course with JavaScript?

I would like to create a curriculum presentation by Java Script similar to the one on Udemy.
https://prnt.sc/22zxxrp
I have tried to put both button and content in the same div and to add an event listener which would on click trigger conditional check if both of the elements are of the same parent and if true to display the content.
But it does not work.
The code would be something like this but with more buttons.
let batonceros = document.getElementsByClassName("batno");
let paragraph = document.getElementsByClassName("para");
batonceros.addEventListener("click", function() {
if( batonceros != paragraph && batonceros.parentNode == paragraph.parentNode) {
batonceros.style.display = "block";
}
else {
batonceros.style.display = "none";
}
});
Not exactly sure what you're trying to accomplish, but maybe this might help. It shows how to reference the parent container to find the relative .para from its .batno
let batonceros = document.querySelectorAll(".batno");
let paragraph = document.querySelectorAll(".para");
batonceros.forEach(button => button.addEventListener("click", e => {
e.target.closest('div').querySelector('.para').classList.toggle('show');
}));
.para {
display: none;
}
.show {
display: block;
}
<div>
<p class='para'>This is a paragraph</p>
<button class='batno'>Button</button>
</div>
<div>
<p class='para'>This is a paragraph</p>
<button class='batno'>Button</button>
</div>
To debug, try to see if it works without checking the parent. Also, no need to check to see if the button equals the paragraph. Also, you are changing the button style, not the paragraph style.
batonceros.addEventListener("click", function() {
paragraph.style.display = "block";
}
If this does cause the paragraph to display, your problem may in your element structure.

Get all IDs of selected/highlighted DIVs

I may be going in the completely wrong direction with what I'm trying to do, so I wanted to ask for help.
Background / Overview
I need to display a paragraph of text and allow a user to select one or more words from the paragraph and save their highlighted text to a database, for just their profile. Actually, hat selection of text will eventually be (1) stored with the highlight AND (2) linked up to another set of highlighted text from another paragraph (basically, I'm tying a phrase from one source to a reference source)
What I've tried...
I have tried to put each word of the paragraph into a DIV (and a unique ID) with each DIV set to float left, so that the display looks okay.
<style>
div { float: left}
</style>
and...using an example:
<div id="GEN_1_1">
<div id="GEN_1_1_1">In</div>
<div id="GEN_1_1_2">the</div>
<div id="GEN_1_1_3">beginning</div>
<div id="GEN_1_1_4">God</div>
<div id="GEN_1_1_5">created</div>
<div id="GEN_1_1_6">the</div>
<div id="GEN_1_1_7">heaven</div>
<div id="GEN_1_1_8">and</div>
<div id="GEN_1_1_9">the</div>
<div id="GEN_1_1_10">earth</div>.
</div>
Which looks like: In the beginning God created the heaven and the earth. (minus the bold)
So far, I have used the
window.getSelection()
function to determine/grab the words that have been highlighted.
I then tried using this:
if (window.getSelection)
{
selected_len = window.getSelection().toString().length;
if (window.getSelection().toString().length>0)
{
div_id = window.getSelection().getRangeAt(0).commonAncestorContainer.parentNode.id;
}
}
to get the ID's for each DIV selected, BUT I only get a single DIV ID returned right now.
Help Request:
Is there are slick way to get the ID for each DIV selected and put it into an Array, so that I can construct a SQL query to put it into the database (the query is easy)? The selected words could total up to several hundred, if not a thousand words, so I need to make sure the solution will work with a ton of words selected.
UPDATE: JSFIDDLE DEMO
I modified the code again. See if it works for you now.
$(document).ready(function () {
$(document).on('mouseup keyup', '.checked', function () {
console.log(window.getSelection());
if (window.getSelection().toString().length>0) {
var count = window.getSelection();
var arr = [];
$('.checked span').each(function(){
var span = $(this)[0];
var isT = window.getSelection().containsNode(span, true);
if(isT){
arr.push($(this).attr('id'));
}
});
console.log(arr,count.toString());
alert(arr);
alert(count.toString());
}
});
});
I created a fiddle for solution. Check it out here: http://jsfiddle.net/lotusgodkk/GCu2D/18/
Also, I used span instead of div for the text selection. I hope that won't be an issue for you. So the code works as you want. It will return the id of the parent span in which text is selected. You can modify it to save the ID into array or as per your needs.
$(document).ready(function () {
$(document).on('mouseup', '.checked', function () {
if (window.getSelection) {
var i = getSelectionParentElement();
console.log(i);
alert('parent selected: ' + i.id);
}
});
});
function getSelectionParentElement() {
var parent = null, selection;
if (window.getSelection) {
selection = window.getSelection();
if (selection.rangeCount) {
parent = selection.getRangeAt(0).commonAncestorContainer;
if (parent.nodeType != 1) {
parent = parent.parentNode;
}
}
} else if ((selection = document.selection) && selection.type != "Control") {
parent = selection.createRange().parentElement();
}
return parent;
}

Javascript Collapsible Menu (hide the other elements)

I have the following working Javascript function:
function collapsible(zap) {
if (document.getElementById) {
var abra = document.getElementById(zap).style;
if (abra.display == "block") {
abra.display = "none";
} else {
abra.display = "block";
}
return false;
} else {
return true;
}
}
When I use the following in html code it displays or hides the "element" div:
<li>Element</li>
Thats working fine. But the problem is, that I want to use the function for multiple links, and then the other elements, that were clicked before, stay, open.
How can I reprogram the code, so that only one div stays open and the other gets closed if i click on another link?
Thanks beforehand!
If you could use jQuery and more importantly jQueryUI accordion I think it would accomplish exactly what you're looking for.
However, without using those two, here is how I would structure it. Like mentioned above, I would use classes to modify the styles of the divs you want shown or hidden. Then the js code can just toggle those classes on each of your elements. The slightly more difficult part (without jquery) is modifying class values since in your final application you may have lots of classes on each div. This is just a very crude example to get you going.
Working JSFiddle Example
Sample DOM
<div >
<li>Element1</li>
<div id='elem1' class='myelem visible'>
Element 1 contents
</div>
</div>
<div >
<li>Element2</li>
<div id='elem2' class='myelem'>
Element 2 contents
</div>
</div>
<div >
<li>Element3</li>
<div id='elem3' class='myelem'>
Element 3 contents
</div>
</div>
Sample JS
window['collapsible'] = function(zap) {
if (document.getElementById)
{
var visDivs = document.getElementsByClassName('visible');
for(var i = 0; i < visDivs.length; i++)
{
visDivs[i].className = visDivs[i].className.replace('visible','');
}
document.getElementById(zap).className += " visible";
return false;
}
else
return true;
}
Sample CSS:
.myelem {
display: none;
}
.visible {
display: block;
}
The way to go is to create a class(or maybe two), like collapsible and active or open that has this style(display: block or none) and then you working adding or removing the class.
The logic would be:
Links that has the class collapsible when clicked would add the active or open class which would give the behavior that remains opens(or active) by css.
If you want to hide others elements you would look for the elements with the class collapsible and then remove the active(or open) class if has any.
Here is my solution: http://jsfiddle.net/g5oc0uoq/
$('.content').hide();
$('.listelement').on('click', function(){
if(!($(this).children('.content').is(':visible'))){
$('.content').slideUp();
$(this).children('.content').slideDown();
} else {
$('.content').slideUp();
}
});
show() and hide() can be used instead of slideUp() and slideDown() if you have performance issues.

CSS button: hover, disabling then re-enabling with javascript

I have some buttons which have a hover effect which makes the button color darker on hover ( with css ).
When the user clicks on those buttons, i disable them via javascript.
when i want the procedure ( game ) to start again and i re-enable the buttons via javascript, the css button: hover effect does not work any more.
Any solutions?
the javascript enable/disable button functions are:
function jsEnableElement(id) {
if ( document.getElementById(id) ) {
document.getElementById(id).style.background = "#3399FF";
document.getElementById(id).style.cursor = "pointer";
document.getElementById(id).disabled = false;
}
}
function jsDisableElement(id) {
if ( document.getElementById(id) ) {
document.getElementById(id).style.background = "#DDDDDD";
document.getElementById(id).style.cursor = "default";
document.getElementById(id).disabled = true;
}
}
I'm not sure why the behaviour breaks when you change the background color of an element eventhough you keep its ID or Class name. But appearently it does.
So another way for you to fix this, and its perhaps a better way is to change the class of the element.
I don't know what element you want to disable, but i'm using a DIV as example. A working demo can be found here:
http://jsfiddle.net/yVVk6/
But just for completness i'll add the code in here aswell
<html>
<head>
<script>
function jsEnableElement(id) {
if ( document.getElementById(id) ) {
document.getElementById(id).removeAttribute("disabled");
document.getElementById(id).className = "enabled";
//document.getElementById(id).disabled = false;
}
}
function jsDisableElement(id) {
if ( document.getElementById(id) ) {
document.getElementById(id).removeAttribute("enabled");
document.getElementById(id).className = "disabled";
//document.getElementById(id).disabled = true;
}
}
</script>
</head>
<body>
<div id="hallo" class="enabled" onclick="jsDisableElement('hallo');">Click me to disable</div>
<div onclick="jsEnableElement('hallo');">Click me to enable it again</div>
</body>
CSS:
.enabled {
background: #3399FF;
}
.enabled:hover {
background: #00FF66;
}
.disabled {
background: #DDD;
}
EDIT:
Just another thing i would like to mention is, if you go with this solution, then i really advise you to use a library like jQuery. It allows you to easily edit, delete or add classes to elements. In this example i simply delete all classes from the element.
I think you can directly give the attribute as shown below:
document.getElementById("btnL1").setAttribute("disabled","true") //to disable the button
document.getElementById("btnL1").removeAttribute("disabled") //enable it again

Javascript if else statement to hide and show div

Please refer to the following codes :
<div id="message-1" onclick="javascript:showresponddiv(this.id)>
</div>
<div id="respond-1" style="display:none;">
</div>
<div id="message-2" onclick="javascript:showresponddiv(this.id)>
</div>
<div id="respond-2" style="display:none;">
</div>
<script type="text/javascript">
function showresponddiv(messagedivid){
var responddivid = messagedivid.replace("message-", "respond-");
if (document.getElementById(responddivid).style.display=="none"){
document.getElementById(responddivid).style.display="inline";
} else {
document.getElementById(responddivid).style.display="none";
}
}
</script>
The codes above already success make the respond div appear when user click on message div. The respond div will disappear when user click on message div again. Now my question is how to make the respond div of 1st message disappear when user click on 2nd message to display the respond div of 2nd message?
You should give the "respond" divs a common class:
<div id="respond-1" class="response' style="display:none;"></div>
Then you can get all divs by using getElementsByTagName, compare the class and hide them on a match:
function hideAllResponses() {
var divs = document.getElementsByTagName('div');
for(var i = divs.length; i-- ;) {
var div = divs[i];
if(div.className === 'response') {
div.style.display = 'none';
}
}
}
We cannot use getElementsByClassName, because this method is not supported by IE8 and below. But of course this method can be extended to make use of it if it is supported (same for querySelectorAll). This is left as an exercise for the reader.
Further notes:
Adding javascript: to the click handler is syntactically not wrong but totally unnecessary. Just do:
onclick="showresponddiv(this.id)"
If you have to do a lot of DOM manipulation of this kind, you should have a look at a library such as jQuery which greatly simplify such tasks.
Update: If always only one response is shown and you are worried about speed, then store a reference to opened one:
var current = null;
function showresponddiv(messagedivid){
var id = messagedivid.replace("message-", "respond-"),
div = document.getElementById(id);
// hide previous one
if(current && current !== div) {
current.style.display = 'none';
}
if (div.style.display=="none"){
div.style.display="inline";
current = div;
}
else {
div.style.display="none";
}
}
Edit: Fixed logic. See a DEMO.
You can add some class to all divs with id="respond-"
e.g
<div id="respond-1" class="classname" style="display:none;"></div>
<div id="respond-2" class="classname" style="display:none;"></div>
Now at first row of your function "showresponddiv()" you should find all divs with class "classname" and hide them.
With jQuery it is simple code:
$(".classname").hide();
jQuery - is a Javascript Library that helps you to easy manipulate with DOM and provides cross-browser compatibility.
Also you can look to Sizzle - it is a JavaScript CSS selector engine used by jQuery for selecting DOM elements
