I learn on how to alert all html code from webpage using this code:
var markup = document.document.innerHTML;
alert(markup);
I want to alert only all <p>
I tried this code
var markup = document.getElementsByTag('p').innerHTML;
alert(markup);`
But it's not working
document.getElementsByTagName("p") returns a HTMLCollection which you can convert to an array using the spread operator. Then you need to get the innerHTML for each element of the array. Finally you can join those innerHTML together to output them:
var pElements = [ ... document.getElementsByTagName("p") ];
var pMarkup = pElements.map( element => element.innerHTML );
alert( pMarkup.join( "\n" ) );
<p>abc<strong>def</strong></p>
<table><tr><td>Don't show this</td></tr></table>
<p>ghi<em>jkl</em></p>
I think you are after HTMLElement.outerHTML
// All p's
const pTags = document.querySelectorAll('p');
const output = [...pTags].map(p => p.outerHTML).join("");
console.log(output);
.red {
color: red;
}

i have a unique case here. So i have 2 divs, one on the left and one on right. How can i make it so that if the height of left div exceeds the height of the div on right, the function should make the heights equal and hide any text for the left div. So if i calculate the offsetheight on load and for one on right is 443 px and one on left is 583 px, it should make both heights equal and height the rest 140px of data of left one.
I created a pen
var text = document.getElementById('overflow_text')
function mounted() {
var toggleBtn = document.getElementById('toggle_text')
var offsetDiv = document.getElementById('offset_height')
var offsetDivHeight = offsetDiv.offsetHeight + 'px'
var textHeight = text.offsetHeight + 'px'
console.log(textHeight)
console.log(offsetDivHeight)
if (textHeight > offsetHeight) {
text.style.maxHeight = offsetDivHeight
text.style.overflow = 'hidden'
text.style.textOverflow = 'ellipsis'
text.style.whiteSpace = 'nowrap'
}
}
#toggle_text {
cursor: pointer;
}

So if you check the console, you will see what the heights of both divs are onLoad. Not sure how i can set the CSS through Javascript. Thank you in advance.
If any one has any other ideas on how to achieve this, i am open to suggestions.
The solution is a bit tricky, since you cannot simply use textOverflow: ellipsis css property if your text has multiple lines.
First we set height of the left text container to the height of the right which is smaller. Then we have to shrink the number of words displayed inside the left container. We remove words from the end of the container until container's scrollHeight is smaller or equal to the container's height.
In this way we know that the container has only as much words as it's able to display with restriction that it's no taller than the right container.
The drawback is that we remove overflowing words from the element so you're no longer able to get original content from this container.
function mounted() {
var leftContainer = document.getElementById('overflow_text')
var rightContainer = document.getElementById('offset_height')
var rightOffsetHeight = rightContainer.offsetHeight;
var leftOffsetHeight = leftContainer.offsetHeight;
if (leftOffsetHeight > rightOffsetHeight) {
leftContainer.style.height = rightOffsetHeight + "px"
var wordArray = leftContainer.innerHTML.split(' ');
while(leftContainer.scrollHeight > leftContainer.offsetHeight) {
wordArray.pop();
leftContainer.innerHTML = wordArray.join(' ') + '...';
}
}
}
Your if statement needs to use the variable name, offsetDivHeight.
if (textHeight > offsetHeight)
offsetHeight is never defined. Do you mean offsetDivHeight?
text.style.whiteSpace = 'nowrap'
If you do this, all of the text in the div will be confined to one line.
Demo with these changes made.
I'm working on a dropdown with javascript. My HTML does not work and I can't find the problem... I think I've done right but maybe it's the link who does not work.
$(document).ready(function() {
$("article.hey > *:not(header)").hide();
$("article.hey header").on("click", function() {
$(this).nextAll("*").slideToggle();
});
});
<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script>
<header>
<article class="hey">

Thanks!
The structure of your HTML must be the header tag inside the article tag:
$(document).ready(function() {
$("article.hey > *:not(header)").hide();
$("article.hey header").on("click", function() {
$(this).nextAll("*").slideToggle();
});
});
<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script>
<article class="hey">
<header>I'm the header 'CLICK ME'</header>

I need to show txt nicely sliding from under image after click. When user will click on other image, previous text have to slide out (not be vissible).

Could someone help me with this one?
When using jquery hide() and show() you can set the parameter duration that will be used in animation duration, see jquery docs. For example, 500 miliseconds:
$(document).ready(function() {
$(".slidingDiv").hide();
$(".show_hide").show();
$('.show_hide').click(function() {
//hide all sliding divs
var arrayLikeOfSlidingDivs = $('.slidingDiv');
arrayLikeOfSlidingDivs.each(function(){
if ($(this).is(':visible')){
$(this).hide(500);
}
});
var isvisible = $(this).next('.slidingDiv').is(':visible');
if ( isvisible ) {
$(this).next('.slidingDiv').hide(500);
} else{
$(this).next('.slidingDiv').show(500);
}
});
});
Ive got a js that runs to see if a maximum amount of characters is reached. Its got text along with href, but when the max amount of characters is reached, the link doesnt work and converts it to just text. When the limit of less then 580 characters, link works. When it does reach the limit, the read more link does work. Any advice or help please and thanks
$(document).ready(function () {
var stylistText = $('#stylistText');
var stylistText2 = document.getElementById("stylistText").innerHTML;
var countActualText = stylistText2.valueOf().length;
var maxLength = 580;
var aElement = document.createElement('a');
var linkText = document.createTextNode(" ...Read more");
aElement.appendChild(linkText);
aElement.href = "#";
if (countActualText > maxLength) {
stylistText.text(stylistText.text().substring(0, 580));
stylistText.append(aElement);
}
});
here is the html
<div class="stylistInfo">
<img id="stylistPhoto" src="images/Test.jpg" alt="peekaboo beans stylist" />
<p id="stylistText">

Change stylistText.text(stylistText.text().substring(0, 580));
to stylistText.html(stylistText.html().substring(0, 580));
However, truncating a block of text that contains HTML may cause other problems, especially if the truncation occurs in the middle of an element. I would recommend rethinking your whole strategy on this.
Suppose we have the following code:
<div id="test" style="width:200px; height: 200px; overflow: hidden;">
<p>Lorem ipsum dolor sit amet, consectetur adipiscing elit. Vivamus
ipsum diam, cursus ornare eleifend quis, posuere id sapien. Vestibulum
et mattis augue. Nulla facilisi. Sed rhoncus facilisis commodo. Sed mattis
commodo lorem, quis varius est facilisis eget. Integer at nunc metus.
Fusce augue odio, elementum et hendrerit vitae, malesuada at urna.</p>
<p>Consectetur adipiscing elit. Vivamus lorem ipsum dolor sit amet,
ipsum diam, cursus ornare eleifend quis, posuere id sapien. Vestibulum
et mattis augue. Nulla facilisi. Sed rhoncus facilisis commodo. Sed mattis
commodo lorem, quis varius est facilisis eget. Integer at nunc metus.
Fusce augue odio, elementum et hendrerit vitae, malesuada at urna.</p>
<p>Sed rhoncus facilisis commodo. Sed mattis lorem ipsum dolor sit amet,
consectetur adipiscing elit. Vivamus ipsum diam, cursus ornare eleifend
quis, posuere id sapien. Vestibulum et mattis augue. Nulla facilisi.
commodo lorem, quis varius est facilisis eget. Integer at nunc metus.
Fusce augue odio, elementum et hendrerit vitae, malesuada at urna.</p>
</div>
The result would be a clipped text.
Is there some way to get invisible text as a substring?
I tried
$("#test :hidden").text();
and
$('#test').children(":hidden").text()
without success.
I'm trying to show pages of text without scrolling. I have a large amount of text (html formatted) and a fixed size div (the text page). I would like to paginate the text on it, just showing one page of text each time.
There is a good answer on this topic already, it provides the javascript you'd need to do this. Like the respondent there though, I would say find another way to do this if you can.
You could use a mono-spaced font like Lucida Console or Courier New and split the string based on a static number of characters that fit in the content area.
