how to hide/remove all text in-between two elements? - javascript

lets say i have this lump of HTML:
<div class="container">
<span class="title">Heading 1</span>
This is a description..<br />
This is the second line..
<div class="image"><img src="image.jpg" /></div>
</div>
What i want to do using jQuery/JavaScript is hide/remove all text and elements between <span class="title"> and <div class="image">.
I've looked all over and found pretty much nothing. Any ideas on how i could do this?

How about something like this? http://jsfiddle.net/ZW8q2/1
var foo = $('.container').children(':not(br)');
$('.container').html('').html(foo);

You could try:
var str = $('.container .title').text() + $('.container .image').html();
$('.container').html(str);
JS Fiddle.

Try this:
Place a tag around what you want to hide, give div an ID name. So in the end your will look like:
<div id = "hideMe" style ="display:block">...Your Content...</div>
Use this javascript:
function hide()
{
document.getElementById('hideMe').style.display = "none";
return;
}
Have the Javascript function called whenever you want to hide the stuff between the div from a button (or other control) like this:
<input type= "submit" onclick ="hide()">

Hide only on certain elements

I'm using a script that checks for any tag that also has a SRC="self". My function should function like this:
Check if img src="self"
If true, hide the parent div
If false, do nothing
Currently the function actually hides every img regardless of src. If I replace the jQuery hide() action then the function works perfectly. It just seems like it isn't quite performing the hide function like I anticipated.
function changeSourceAll() {
var images = document.getElementsByTagName('img');
for (var i = 0; i < images.length; i++) {
if (images[i].src.indexOf('self') !== -1) {
$(".redditThumbnail").hide();
}
else (){}
}
}
changeSourceAll();
Sample HTML is below. I have multiple .listrow div elements identical to this and the function removes all the .redditThumbnail divs.
<div class="listrow news">
<div class="newscontainer">
<div class="redditThumbnail"></div>
<div class="articleheader news">
<div class="actionmenu">
<p class="mediumtext floatleft alignleft">
author
</p>
<div id="redditUsername"></div>
<div class="floatright">
<div class="redditPermalink material-icons"></div>
</div>
</div>
<p class="redditTitle mediatitle news"></p>
</div>
</div>
</div>
Thanks!
You could use an attribute-equals selector to find all of the <img> elements that point to "self" and then hide their parents :
// Hide the closest thumbnail for elements that match this constraint
$('img[src="self"]').closest('.redditThumbnail');
Example
$(function() {
$('button').click(function(){
$('img[src="self"]').closest('.redditThumbnail').hide();
});
});
<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script>
<div class='redditThumbnail'>
A (has self)
<img src='self' />
</div>
<div class='redditThumbnail'>
B (doesn't have self)
<img src='self-test' />
</div>
<div class='redditThumbnail'>
C (has self)
<img src='self' />
</div>
<hr />
<button>Hide Self-Referencing Images</button>
The issue with hiding every img is because you select and hide all .redditThumbnail elements for every matching item. To fix this you could use this:
$(images[i]).closest('.redditThumbnail').hide();
However a better approach entirely would be to use filter() and find only the .redditThumbnail elements which match the requirements. Try this:
$('.redditThumbnail').filter(function() {
return $(this).find('img[src="self"]').length != 0;
}).hide();
You are hiding all: $(".redditThumbnail").hide();. I guess you should do something like $(images[i]).hide();

Hiding div that contains specific string

I've been trying to hide divs that contain particular string using the other solutions suggested on this site, however none worked (most likely due to my inexperience with jQuery)
I'd like to completely hide all divs that (in this example) contain the string 'zynthesized'
<div class="photos-wrapper" id="detailPhoto-977355202965894535_11842652">
<div class="pseudo">
zynthesized
</div>
<div class="image-wrapper">
<img src="https://scontent.cdninstagram.com/hphotos-xfp1/t51.2885-15/s150x150/e15/11195725_518243828313545_1133319712_n.jpg"></div>
<div class="activites">
<span class="popular_picto ss-star "></span>
<div class="album-relative detail-photo-album-977355202965894535_11842652" style="display: none;">
<input type="hidden" class="apalbumsPhoto" value="977355202965894535_11842652">
<input type="hidden" class="apalbumsPhoto-977355202965894535_11842652" value="">
</div>
<span class="nb_comment_score">0</span>
<span class="comment_picto ss-chat"></span>
<span class="nb_like_score">4</span>
</div>
<div class="nouveau-commentaire">
<textarea id="comment-977355202965894535_11842652" class="textareaCommentaire" placeholder="Your comment"></textarea>
<img src="http://static.iconosquare.com/images/loading.gif" class="commentLoading">
</div>
</div>
From what I've seen something like
$('.photos-wrapper:contains("zynthesized")').hide()
Should be closest to what I need, but I've had no luck with it.
Any help would be amazing!
Thanks for the help guys! Turns out that the script was working however as the page loaded new divs automatically when scrolling, the script had to be run after the page loaded them.
The final script looks like
$(window).load(function(){
$(".photos-wrapper:contains('zynthesized')").hide();
});
$(window).on('scroll', function() {
var y_scroll_pos = window.pageYOffset;
var scroll_pos_test = 150;
if(y_scroll_pos > scroll_pos_test) {
$(".photos-wrapper:contains('zynthesized')").hide();
}
});
Hopefully this helps anyone looking to do something similar!
You can simply use a regex.
<script>
var ptrn = /zynthesized/g;
$( "div" ).each(function( index ) {
if(ptrn.test($( this ).text())){
$( this ).hide();
}
});
</script>

Find sibling with Javascript and Hammer.js

I have made a simple system which detects double taps. I want to show a heart icon when someone double taps on an image, just like on Instagram.
This is what my code looks right now:
var elements = document.getElementsByClassName('snap_img');
[].slice.call(elements).forEach(function(element) {
var hammertime = new Hammer(element),
img_src = element.getAttribute('src');
hammertime.on('doubletap', function(event) {
alert(img_src); // this is to test if doubletap works
// Some javascript to show the heart icon
});
});
This is what the HTML looks like:
<div class="snap_item">
<div class="snap_item_following_info">
<img class="snap_item_following_img" src="res/stat/img/user/profile/small/1.fw.png" alt="#JohnDoe" />
<a class="snap_item_following_name" href="#">#JohnDoe</a>
<div class="snap_too">
</div>
</div>
<img class="snap_img" src="res/stat/img/user/snap/43/2.fw.png" alt="#ErolSimsir" />
<div class="like_heart"></div>
<div class="snap_info">
<div class="snap_text">
LA is the shit...
<a class="snap_text_hashtah" href="#">#LA_city_trip</a>
</div>
<div class="snap_sub_info">
<span class="snap_time">56 minutes ago</span>
<div class="like inactive_like">
<div class="like_icon"></div>
<div class="like_no_active">5477</div>
</div>
</div>
</div>
</div>
So when the element 'snap_img' is double tapped, I need to get the element 'like_heart' which is one line below the snap_img element. How do I get that sibling element and fade it in with JQuery?
Like this
[].slice.call(elements).forEach(function(element) {
var hammertime = new Hammer(element),
img_src = element.getAttribute('src');
hammertime.on('doubletap', function(event) {
alert(img_src); // this is to test if doubletap works
$(element).next().text('♥').hide().fadeIn();
});
});
P.S. I've added that heart text, since the sibling was empty.
On the event handler, i would do $(element).parent().find('.like_heart').fadeIn(); So the code is not dependant on the element ordering.
(To clarify to selector: take the parent element which is the div.snap_item and find an element with class like-heart inside it)

If href equals id of another div do function

I have a hidden div with the details of a thumbnail that is visible on the page. When you click on the thumbnail, it should fadein or slideup the div with details.
I have set with jquery incremented ID's to each ".portfolio-item-details" to identify each one and then have set with jquery the same ID's to the href of the thumbnail.
<section id="portfolio1" class="portfolio-item-details hidden">content</section>
<a class="open-portfolio-item-details" href="#portfolio1" title="">
<img src="thumbnail.jpg">
</a>
<section id="portfolio2" class="portfolio-item-details hidden">content</section>
<a class="open-portfolio-item-details" href="#portfolio2" title="">
<img src="thumbnail.jpg">
</a>
Since this is done dynamically, how can I with jquery fadeIn or slideUp the ".portfolio-item-details" if the href is equal to the ID. Basically thumbnail with "#portfolio1" should slide up the div with "#portfolio1" on click.
This is my jquery code which to add the IDs and HREF is working perfectly but not working to slideUp or fadeIn the div with the same ID.
$(document).ready(function () {
var i=0;
$(".portfolio-item-details").each(function(){
i++;
var newID="portfolio"+i;
$(this).attr("id",newID);
$(this).val(i);
});
var i=0;
$(".open-portfolio-item-details").each(function(){
i++;
var newReadMoreHREF="#portfolio"+i;
$(this).attr("href",newReadMoreHREF);
$(this).val(i);
if ($(".portfolio-item-details").attr("id") == "newReadMoreHREF") {
$(this).fadeIn();
}
});
});
SOLUTION
Thanks to Austin's code, I was able to modify it to work with mine.
Check here: http://jsfiddle.net/jdoimeadios23/xpsrLyLz/
You want something like this?
HTML
<div class="image" value="1">
<img src="thumbnail.jpg" />
</div>
<div id="portfolio1" class="details">details</div>
<div class="image" value="2">
<img src="thumbnail.jpg" />
</div>
<div id="portfolio2" class="details">more details</div>
JS
$(document).ready(function () {
$('.details').fadeOut(1);
$(".image").click(function () {
var num = $(this).attr("value");
$("#portfolio"+num).fadeIn(1000);
});
});
JSFiddle Demo
You don't even need to bother with ID's so long as the next div below each image is it's details.
The problem is in this block
if ($(".portfolio-item-details").attr("id") == "newReadMoreHREF") {
$(this).fadeIn();
}
Because you're having two errors, the first one is that newReadMoreHREF is a variable, not a string in your HTML or a value to any variable and so on.
Second thing is, that in the variable declaration you're using "#portfolio"+i;, which would be good if you were about to select an element. But using it in the jQuery iif statement with .attr('id') will again cause a havoc.
The thing that you need is something like this
$(".open-portfolio-item-details").each(function(){
i++;
var newReadMoreHREF="portfolio"+i; // removed #
$(this).attr("href",newReadMoreHREF);
$(this).val(i);
if ($(".portfolio-item-details a").attr("id") == newReadMoreHREF) {
// you need to access the hyperlink in the element, not
// the element itself. this portfolio1 ID is of a hyperlink
// again here, this is referencing the main iterator.
$(this).fadeIn();
// are you sure you want to fade the .open-portfolio-item-details?
}
});
Removed the hash sign and then called the variable value to check against. It would execute to be true if the condition is true.
Try this:
HTML:
content
<section id="portfolio2" class="portfolio-item-details hidden">content</section>
<a class="open-portfolio-item-details" href="#portfolio2" title="">
<img src="thumbnail.jpg">
</a>
<div id="portfolio1" class="portfolio" hidden>Portfolio 1</div>
<div id="portfolio2" class="portfolio" hidden>Portfolio 2</div>
Jquery:
$('a.open-portfolio-item-details').on('click', function (e) {
e.preventDefault();
var id = $(this).attr('href');
$('.portfolio').hide();
$('.portfolio' + id).fadeIn();
});
Couldn't get the fiddle link for some reason.
Edit:
I don't know the name of the class that shows the content you want displayed, so as an example I'm using portfolio. Try putting this code into a fiddle

Changing content in a div when a link is clicked

I am trying to change a div content box when a link above that box is clicked. I added a click function to the individual buttons then the corresponding dive containing the content for that particular box should be displayed.
When I apply the jQuery to the page, the content does not change according to the link that is clicked and the page displays awkwardly.
This is the jsfiddle I'm working with.
The webpage I'm working with is here.
Place where am i making the mistake.
The jQuery I'm working with so far looks like this
$(document).ready(function() {
$('.question1').click(function(){
$('.new_member_box_display').load('#answer1');
})
$('.question2').click(function(){
$('.new_member_box_display').load('#answer2');
})
$('.question3').click(function(){
$('.new_member_box_display').load('#answer3');
})
$('.question4').click(function(){
$('.new_member_box_display').load('#answer4');
})
});//end of ready
The HTML I'm working with looks like this :
<div class="new_member_box">
<h4>Vision</h4>
</div>
<div class="new_member_box">
<h4>Church History</h4>
</div>
<div class="new_member_box">
<h4>Becoming a Member</h4>
</div>
<div class="new_member_box">
<h4>Pastor-in-Training</h4>
</div>
</div>
<div class="clear" class="question"></div>
<div id="answer1">
1
</div>
<div id="answer2">
2
</div>
<div id="answer3">
3
</div>
<div id="answer4">
4
</div>
<div class="new_member_box_display" id="question">
Text will appear here when one of the tabs above is clicked
</div>
load() loads an external file with ajax, not elements on your page. You're probably just trying to hide and show elements :
$('[class^="question"]').on('click', function(e){
e.preventDefault();
var numb = this.className.replace('question', '');
$('[id^="answer"]').hide();
$('#answer' + numb).show();
});
FIDDLE
Here's a fiddle that does what I think you're looking to do. There are cleaner ways to do it, but this should work.
http://jsfiddle.net/PZnSb/6/
Basically you want to set the inner html of one element to the inner html of another, like this:
$('.question1').click(function(){
$('.new_member_box_display').html($('#answer1').html());
})
instead of this:
$('.question1').click(function(){
$('.new_member_box_display').load('#answer1');
})
It seems you just want the text to change when you click, try this.
$(document).ready(function() {
$('.question1').click(function(){
$('.new_member_box_display').text($('.answer1 ').text());
});
$('.question2').click(function(){
$('.new_member_box_display').text($('.answer2').text());
});
$('.question3').click(function(){
$('.new_member_box_display').text($('.answer3').text());
});
$('.question4').click(function(){
$('.new_member_box_display').text($('.answer4').text());
});
});
