I have a PHP script that outputs data. It is all conveniently wrapped inside a p class.
It outputs the same data and same class multiple times, so there are like 6 blocks of text, each block being wrapped inside p class.
I need to reduce each block to 3 lines using any method possible. I already tried using PHP in various ways to no avail.
I came across Clamp.js which looked great. The only issue is, it will only work using ID. I can change the p class tags to p id, however, they'd all have to share the same ID, which, obviously, won't work.
Here's the current code I've tried:
var module = document.getElementsByClassName("clampjs");
$clamp(module, {clamp: 1});
And the HTML (times 6):
<div class="headtab">
Forum title<p class="bold">Posted By:</p> username <p class="bold">In:</p> category</div>
<div class="maintext">
<p class="clampjs">TEXT I WANT TO BE CLAMPED</p>
</div>
Like I say, it works fine when I use an ID, but obviously, only for the first block of text as the ID HAS to stay the same, that's why I'm using p class.
Sadly, what I've tried above doesn't work at all. Does anybody know a little fix for this script, or perhaps a different script that will clamp objects using a class element? Jquery is acceptable too.

Working code thanks to the accepted answer:
$(document).ready( function() {
$('.clampjs').css({ //changes the css of the clicked content.
'max-height':'75px', //give what ever height you want.
'overflow':'hidden'
});
});
this could be easily done with just editing your css
$('.clampjs').click( function() {
$(this).css({ //changes the css of the clicked content.
'height':'100px', //give what ever height you want.
'overflow':'hidden'
});
});
just now tested in my page it works...

The link below is supposed to reveal more text when clicked, which it does, however the text uses all default styling, which cannot be seen on my black background that I use for the page. I have tried to style the tag where the text is added through JavaScript, but the added text still uses the default style.
Below is the code I have used:
HTML:
<p>
This movie might seem boring to you at first and you
might not get it after <br>first time viewing, like I did. But this
is one of the greatest movies ever made.....

<p id="atext" class="atext">dqdas</p>
<script src="Home.js"></script>
</p>
and JavaScript:
function more(e) {
e.preventDefault();
document.getElementById("atext").style.color= "white";
document.getElementById("atext").outerHTML = 'It touches many issues in our lives and packs a hell of a plot twist';
}
Simply use innerText rather then outerHTML. This should solve the issue.
I believe this happens because setting the HTML of an element overwrites any styles it may have. Setting the text does not do this.
Also, it is generally best to use innerText when necessary, as it reduces the risk of errors like yours occurring.
I have two hidden <div> elements which are hidden at the bottom of my page like so:
<div class="hidden-unit" style="display:none;">
<h1>ad unit one</h1>
</div>
<div class="hidden-unit" style="display:none;">
<h1>ad unit two</h1>
</div>
Further up my page I have another two div elements, like so...
<div class="visible-unit"></div>
<div class="visible-unit"></div>
I would like to loop through each of the hidden units, place the content from the first .hidden-unit into the first .visible-unit and then likewise for the second.
The content that sits within each .hidden-unit will actually be an inline script used for displaying ads, this is passed through from an array into a view that I have created in PHP so there is a strong possibility that more content could be added to the array or removed, so this loop needs to accommodate for such situations.
I have tried a number of solutions using jQuery's .each() but I can't seem to get it right. I've also created a JSFiddle should anyone want to demonstrate a solution:
https://jsfiddle.net/p89sq2df/3/
I've tried loads of different combinations and the latest attempt only seems to be populating the .visible-unit elements with the 'ad unit two' text.
$('.hidden-unit').each(function() {
$('.visible-unit').html($(this).html());
});
Anyone had to do anything like this before? I appreciate it's an odd one.
You can try using the index:
$('.hidden-unit').each(function(index) {
$('.visible-unit').eq(index).html($(this).html());
});
var visibleUnits = $('.visible-unit').toArray();
var x = 0;
$('.hidden-unit').each(function() {
visibleUnits[x].html($(this).html());
x++;
});
The gotcha is that there could be more .hidden-unit elements than .visible-unit elements, which would cause an exception. But this you put you on the right track.
You need to use the index the elements so you update matching instances. This can be done using each or html(function)
$('.visible-unit').html(function(index){
return $('.hidden-unit').eq(index).html();
});
Since you mention that the content is loaded by script originally, you may need to allow time for any asynchronous loading (if any) in the scripts
DEMO
Rather than trying to match indices and having to maintain two lists of divs, you can clone the hidden divs and add them to a container, or insert them before or after another element if you really don't want a container element.
$(".hidden-unit").clone()
.removeClass("hidden-unit")
.removeAttr("style")
.addClass("available-unit")
.appendTo(".container");
Working fiddle here: https://jsfiddle.net/ygn34zL8/
I picked up some code on CodePen to help me dynamically replace the content of divs. It works, but as often happens when borrowing someone's code, I can't actually mold it to what I want it to do.
The original code provides pictures of animals, and when you click it, it sends the text of the name of the animal to a div. The Javascript looks like this:
$('#kittens').click(function() {
$('div').html('Kittens');
});
$('#aardvark').click(function() {
$('div').html('Aardvark');
});
I'm applying it to a more complicated webpage, so I really can't have it just replace the first level div with the word "Kittens."
I've found that by keeping the single quotes, I can put any text or code I want in there and it works just fine, but only if I'm writing to the first level div.
So I figure to target it, I should just give it the div ID. Something like:
$('#kittens').click(function() {
$('myDivName').html('Kittens');
});
This does nothing. I've also tried 'id=myDivName' , 'id="myDivName"' , id: myDivName , and a few others I can't recall right now. Nothing I can come up with seems to work.
Does anybody know how this parameter works and how I can get it to target just the div I want?
jQuery selectors work just like CSS selectors, so instead of $('myDivName'), do $('#myDivName')
when referencing an element in jquery, you need to use it's css selector. For an element with an id "myDivName" that selector would be #myDivName so your jquery would look like:
$('#kittens').click(function() {
$('#myDivName').html('Kittens');
});
I've tried editing this code a number of ways (using if statments and each statements) with nothing working. The idea is so simple; if a div contains this specific text, I want to change the src attribute of the image in that div only.
I can't seem to figure out what I'm missing. The code below changes all the images in all divs with that class rather than just the ones that contain the specific text. I've tried to work in 'this' but apparently don't understand how it affects the function.
$(document).ready(function(){
$('.my-content').filter(':contains("Top")').find('img').attr("src", "http://www.samplestuff.com/kids/test.png");
});
Could someone kindly point me in the right direction of what I need to change to make the script target only images in the div that contain the text instead of all div with that class because one of the div did contain that text (I think that's what triggers it; I may be off about that too).
Try this:
$(document).ready(function(){
$('.my-content:contains("Top")').find('img').attr("src", "http://www.samplestuff.com/kids/test.png");
});
See jQuery :contains docs
Edit
Actually I think your answer should work as well. Seems to work fine in this jsfiddle, can you post your markup?
$('div').filter(':contains("Top")').css("color", "red")
<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script>
<div>Top</div>
<div>Right</div>
<div>Bottom</div>
<div>Left</div>
I have a div that will appear on the page at a separate point. It doesn't always appear on the page and can be added via a CMS if needed. There's a line of text that will appear within the body. If the user has decided to have this div added, it would need to be moved into position via jquery. So, I have this text:
<p><strong>Key Facts:</strong></p>
I want to find it using jquery, then move the other div in front of it. I tried a couple of different ways to select this text then move the div in front of it and haven't had any luck. The best way I found to find the text was to do this:
var foundin = $('*:contains("<p><strong>Key Facts:</strong></p>")');
From that point, to move the div into position, I thought I could something like this:
$('#DivIWantToMove').insertBefore($foundin);
That didn't work, though. I also looked at this:
$( $foundin ).before( $('#DivIWantToMove') );
AS you might imagine, since you're reading this, that didn't work either. So, I'm asking you, is it possible to do what I want? I'm fairly constrained by the CMS that we are using. The DIV I need to move will always be someplace on the page and I have to move it. The client doesn't want to have to add a class to <p><strong>Key Facts:</strong></p> so I'm let with this. If I could have a class on <p> then it would be super easy. I've already done it. The client doesn't like having an extra step. Any ideas?
I think contains selector only looks for text, not html tags. so you have to modify your contains selector. if your html is like this -
<div>
<p><strong>Key Facts:</strong>
</p>
</div>
<div id="move">something something</div>
and you want to move your <div id='move'> in front of p, then try this -
var foundin = $('p:contains("Key Facts")');
var divtomove = $('div#move');
foundin.before(divtomove);

Update also look into this QA: jQuery :contains with html. Instead of using contains you can use one of the methods from there.
