On my project I have a div which is a text area where I can wrap text in to code format.
I also have a button with a id="preview"
Is it possible in another div to display the output of the text area once click on preview button in a front end view like what it would be like on IE or FIREFOX.

function wrapText(elementID, openTag, closeTag) {
var textArea = $('#' + elementID);
var len = textArea.val().length;
var start = textArea[0].selectionStart;
var end = textArea[0].selectionEnd;
var selectedText = textArea.val().substring(start, end);
var replacement = openTag + selectedText + closeTag;
textArea.val(textArea.val().substring(0, start) + replacement + textArea.val().substring(end, len));
}
$('#bold').click(function() {
wrapText("widget", "<strong>", "</strong>");
});
$('#italic').click(function() {
wrapText("widget", "<em>", "</em>");
});
$('#underline').click(function() {
wrapText("widget", "<u>", "</u>");
});
$('#code').click(function() {
wrapText("widget", "<pre><code>", "</code></pre>");
});
Change your ID of preview button, like this:
<button id="preview-btn">Preview</button>
And in your JS:
$('#preview-btn').on('click', function () {
$('#preview').html($('#widget').val());
});

Hello There , I will appreciate a lot any help with my code , I need to count all letters per one <p> Tags and show it on the end of <p> tag but my code count all of <p> tags which I have on the page and put it together in every of them , can any body give me advise what is . wrong and how to fix it , Thank you so much
Because $('p') will find every <p> in page the same way you are using it to set up the initial query
You want the specific instance inside the each which is $(this) and you want append() not appendTo()
$('p').each(function (index) {
var letters = $(this).text().length;
$(this).append('<span style="color:red"> Here is ' + letters + '</span>');
});

Is it possible to run the browser's in built spell checker on divs which aren't contenteditable? The below code works for checking spelling, but the div must be contenteditable and the spell check is only executed once the div is put into focus.
<div contenteditable="true" spellcheck="true">
This paragraph gets spell checked when the div comes into focus
</div>
I want to display a full page of html and have the red squiggly lines underneath all the mis spelled words
Let me say, these steps might work:
Make all the <div> to be focussable by adding a tabindex attribute.
Once focussed, using jQuery (as it is not possible using CSS), add contenteditable attribute.
Once blurred, remove the contenteditable attribute.
Snippet
$(function () {
$(".ce").focus(function () {
$(this).prop("contenteditable", true);
}).blur(function () {
$(this).prop("contenteditable", false);
});
});
<script src="https://code.jquery.com/jquery-2.2.4.js"></script>
<input type="text" placeholder="Click here and press tab!" />
<div class="ce" tabindex="0">Lorem ipsum dolor sit amet, consectetur adipisicing elit. Corporis dolorem consequatur doloribus at, quam ipsam repudiandae libero ullam, commodi cum hic nam odit reiciendis? Distinctio inventore quasi, ex cupiditate neque.</div>
<div class="ce" tabindex="0">Sunt, consequatur. Dolorem odio nihil minima, in autem corrupti. Animi atque, eius laudantium. Excepturi laudantium suscipit esse nulla tempore aspernatur architecto. Dolorem a impedit, dolor voluptatum repellat mollitia itaque quod.</div>

<div class="ce" tabindex="0">Maxime, totam laudantium accusantium itaque sint possimus ex minus deleniti adipisci reprehenderit commodi illo corporis provident sed tempore architecto molestiae! Molestiae voluptas magni, non, ex assumenda quibusdam aliquam vitae ab.</div>
<div class="ce" tabindex="0">Quibusdam magnam, maiores eveniet commodi consequuntur sapiente, deleniti praesentium eius blanditiis. Suscipit fugit in repellendus quis ducimus illum, tempore voluptatem incidunt recusandae a perferendis id, distinctio vitae voluptatibus quibusdam necessitatibus.</div>
I used the following code to apply the spell checker using jquery-2.2.1.js. I made all divs contenteditable and then after view loaded ran:
$('.content-container').each((i, el: any) => {
$(el)[0].focus();
$(el)[0].setAttribute('contenteditable', 'false');
})
How do I make it so that if I click outside a paragraph element then the background color is removed? Note I want to it to only be able to highlight one p at a time.
$('p').click(function() {
$('p').removeClass('yellow');
$(this).addClass('yellow');
});
.yellow {
background: yellow;
}

Here is what you want:
$('p').click(function(e) {
$('p').removeClass('yellow'); //If there is any p with class yellow, it removes that
$(e.target).closest('p').addClass('yellow'); //This find closest target when you click, in our case current paragraph(p)
});
$(document).click(function(e){ //Here is when you click in your entire document
if($(e.target).closest('p').length==0) { // If click is not paragraph
$('p').removeClass('yellow'); //It removes this class existed from any paragraph
}
})

</div>
</div>
Use this code
$("p").click(function (e){
$("p").removeClass("yellow");
$(this).addClass("yellow");
});
$(document).click(function (e){
var element = $("p.yellow");
if (!element.is(e.target) && element.has(e.target).length === 0)
element.removeClass("yellow");
});
.yellow {
background: yellow;
}
<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script>
<p class="yellow">Text text text</p>
<p>Text text text</p>
<p>Text text text</p>
You can set a listener to the <body> and check if the click was onto a <p>:
$('body').click(function(event) {
if(!$(event.target).is('p')) {
$('p').removeClass('yellow');
}
else {
$(event.target).addClass('yellow');
}

I need scrollY position of searched text. How to find text in body and get scrollY position of the found text.
Following code is an example about question:
(all is clear)
<script>
function getScrollYPosition(var str){
/* step 1: search str in <body> and found.
* step 2: get scrollY position of found str.
* step 3: return position. (500)
*/
}
</script>
<body>
<p>Hello world</p> /*For example scrollY position is 500*/
<p>...</p>
<p>...</p>
</body>
You could first match the text string,
wrap it into an (span) element
and than calculate that element offset position
Here's a quick example
var word = 'dolor';
var rgx = new RegExp('\\b('+word+')\\b', 'ig');
// CREATE SPAN ELEMENTS WHAT WILL WRAP THE QUERY STRING (WORD)
$('div, div *').contents().filter(function() {
return this.nodeType === 3;
}).each(function() {
$(this).replaceWith($(this).text().replace(rgx, "<span class='match'>$1</span>"));
});
// COLLECT ALL SPAN POSITIONS
var positions = $('.match').map(function(){
return this.getBoundingClientRect().top;
}).get();
alert(positions);
div{font-size:50px;}
span.match{background: gold;}

You could be a little more specific with your answer. If I understand correctly you need to find an element that contains a given text and get its vertical offset. You could try the following:
$($(":contains(YOUR_TEXT)").slice(-1)[0]).offset().top
I am working on my own Lorem Ipsum generator, with the added bonus of generating the corresponding HTML formatting code in a box beside it.
So, the paragraph is generated via this button
<button id="generate" type="button" onclick="LoremIpsumRandom()">1 Paragraph</button>
and is generated here
<p id="textarea"></p>
function LoremIpsumRandom()
{
//global to store previous random int
_oldInt = null;
var pickRandom = function(paragraphArray)
{
//random index of paragraphArray
var randomInt = Math.floor(Math.random()*paragraphArray.length);
//ensure random integer isn't the same as last
if(randomInt == _oldInt)
pickRandom(paragraphArray);
else{
_oldInt = randomInt;
return paragraphArray[randomInt];
}
}
//your lorem ipsum paragraphs
var paragraphArray = [

//update element content (e.g. `<div>` with paragraph

No point including the CSS to be honest - it's just standard text boxes and auto-generated buttons.
So, the issue is that although I can generate the normal paragraph in the id="textarea" section, I want to be able to generate a raw HTML version as well (with the paragraph and line breaks code being shown.) So far, I've been able to generate the raw HTML with no issues, but when I added #pixelbobby 's section (which makes sure that when a sentence is selected, the next selection won't be the same, as true randomness can sometimes generate), the code doesn't work. In some instances, it's generated the raw HTML, but the generated paragraph is a different one.
The other functions (generating lists, multi-paragraphed sections and multi-levelled lists) utilise the raw HTML and output correctly, and it all runs smoothly. The raw HTML is always outputted to
<p id="textarea-code"></p>
which is next to the first textarea section.
Can someone tell me how I can modify the script so that the raw HTML part of the script generates the same paragraph as the result of the pickRandom(paragraphArray)
So,
This - document.getElementById("textarea-code").innerText = pickRandom("<P>" + (paragraphArray) + "</P>");
needs to be the same as - document.getElementById("textarea").innerHTML = pickRandom(paragraphArray);
but with the raw HTML specified in the pickRandom() part of the line.
Can anyone help?
Thanks :)
You can save the result of pickRandom(paragraphArray) in a variable and use it twice:
var randomParagraph = pickRandom(paragraphArray); //save the result of pickRandom
document.getElementById("textarea").innerHTML = randomParagraph;
document.getElementById("textarea-code").innerText = "<P>" + randomParagraph + "</P>");
