Generate link based on data attributes - javascript

I am trying to write a little jQuery script that checks a set of div's to see if they have a data-name attribute. For the ones that have a data-name, it will create a link. The href of that link should be the name of the data-value plus contain the file extension (eg. .txt).
Everything seems to work OK except when I try to add the data value onto the link. The ultimate result of this script is to output something like this for each of those div's:
<p class="data-link">Edit
Below is my script. I have identified that area that I am having issue with.
var dataNameWrappers = $("div#desktopSidebar div[data-name]");
dataNameWrappers.each(function() {
var dataNameWrappers_action = "" + $(this).attr("data-name");
$(this).prepend("<p class='edit-link'><a>Edit</a></p>");
var dataNameWrapperEditLink = $("div#desktopSidebar p.edit-link a");
dataNameWrapperEditLink.each(function() {
$(this).attr('href', <<stuck_here>>);
});
});
Any help will be great.
Thanks
As requested, here is my sidebar HTMl structure

I don't know why you are using a second loop to add the HREFs when you already have everything you need.
Working fiddle here: http://jsfiddle.net/Q4j8S/.
HTML:
<div id="desktopSidebar">
<div class="sidebar userbox">
<h3 class="sidebarheader"> Welcome {{username}}}</h3>
</div>
<div data-name="social_media_sitewide" class="sidebar socialmedia">
<h3 class="sidebarheader">Follow Tennis-Chat</h3>
</div>
<div data-name="site_promotions" class="sidebar promotions">
<h3 class="sidebarheader">Current Promotions</h3>
</div>
<div data-name="livescores" class="sidebar Livescores">

JavaScript:
var dataNameWrappers = $("div#desktopSidebar div[data-name]");
dataNameWrappers.each(function() {
var dataNameWrappers_action = $(this).attr("data-name");
console.log('data-name ' + dataNameWrappers_action);
$(this).prepend('<p class="edit-link">Edit</p>');
/* Don't need this
var dataNameWrapperEditLink = $("div#desktopSidebar p.edit-link a");
dataNameWrapperEditLink.each(function() {
$(this).attr('href', dataNameWrappers_action);
});
*/
});

Instead of iterating through the a tags after you do the prepend, it may be better to make the HTML fragment with the desired href attribute.
Here is the code that accomplishes that:
$('#desktopSidebar .sidebar[data-name]').each(function(index, el){
var href = $(el).attr('data-name') + ".txt";
$(el).prepend('<p class="edit-link">Edit');
});

jquery wont set image src from another image

I have started some blogs using Weebly now I want to do several changes to the blog UI, everything went well until I wanted to do this. I wanted to get the image path from the image inside blog-content and set it on the blog-post-image. In my head, this jquery looks logical, but somewhere error lays.
Few things to care about, I should use each because there are many of the blog posts and I cannot use ids because of the same reason, cannot use the same id multiple times.
HTML:
$('.blog-post-image').each(function() {
var $me = $(this);
var blogPostImage = $me.siblings('.blog-content').children('img').attr('src');
$me.attr('src', blogPostImage);
});
<script src="https://cdnjs.cloudflare.com/ajax/libs/jquery/3.3.1/jquery.min.js"></script>
<div id="blog-post-746510653886732592" class="blog-post">
<div class="blog-header">
<div class="blog-post-container">
<h2 class="blog-title">
</h2>
<p class="blog-date">
<span class="date-text">
15/6/2021
</span>
</p>
<div>
<img class="blog-post-image" />
</div>
</div>
</div>
<div class="blog-content">
<div>
<div class="wsite-image wsite-image-border-none " style="padding-top:10px;padding-bottom:10px;margin-left:0;margin-right:0;text-align:center">
<a>
<img src="/uploads/7/7/9/0/77909082/820610853.jpg" alt="Picture" style="width:100%;max-width:1100px">
</a>
<div style="display:block;font-size:90%">
</div>
</div>
</div>
.blog-post-image doesn't have any siblings. Siblings are immediate children of the same parent element, but there are no other elements in the div containing <img class="blog-post-image" />.
You need to go up to the .blog-header to get its sibling.
Also, instead of using .each(), you can use a function in .attr(). It automatically loops, and assigns the return value to the attribute.
$('.blog-post-image').attr('src', function() {
return $(this).closest('.blog-header').siblings('.blog-content').find('img').attr('src');
});
<script src="https://cdnjs.cloudflare.com/ajax/libs/jquery/3.3.1/jquery.min.js"></script>
<div id="blog-post-746510653886732592" class="blog-post">

Two things:
1.) .blog-content is not a sibling of .blog-post-image
2.) .children() only looks one level deep to find the element you are looking for.
What you need to do is traverse upwards to find a sibling of .blog-content and then use the .find() function to do a deep search of the given DOM node to find what you're looking for.
$('.blog-post-image').each(function() {
var me = $(this);
var blogPostImage = me.parent().parent().parent().siblings('.blog-content').find('img').attr('src');
me.attr('src', blogPostImage);
});

Link simillary name classes so that when one is clicked the other is given a class

Basically, I'm asking for a way to optimize this code. I'd like to cut it down to a few lines because it does the same thing for every click bind.
$("#arch-of-triumph-button").click(function(){
$("#arch-of-triumph-info").addClass("active-info")
});
$("#romanian-athenaeum-button").click(function(){
$("#romanian-athenaeum-info").addClass("active-info")
});
$("#palace-of-parliament-button").click(function(){
$("#palace-of-parliament-info").addClass("active-info")
});
Is there a way to maybe store "arch-of-triumph", "romanian-athenaeum", "palace-of-parliament" into an array and pull them out into a click bind? I'm thinking some concatenation maybe?
$("+landmarkName+-button").click(function(){
$("+landmarkName+-info").addClass("active-info")
});
Is something like this even possible?
Thanks in advance for all your answers.
EDIT: Here's the full HTML.
<div class="landmark-wrapper">
<div class="page-content landmark">
<div class="heading span-after">
<span>Arch of Triumph</span>
</div>
<div class="landmark-button" id="arch-of-triumph-button"></div>
</div>
</div>
<div class="landmark-wrapper">
<div class="page-content landmark">
<div class="heading span-after">
<span>Romanian Athenaeum</span>
</div>
<div class="landmark-button" id="romanian-athenaeum-button"></div>
</div>
</div>
----------------------------------------------------------
<div class="landmarks-info-wrapper">
<div class="landmark-info" id="arch-of-triumph-info">
<div class="info-landmark section">
<span class="landmark-title">Arch of Triumph</span>
<span class="landmark-coord">44°28′1.99″N 26°4′41.06″E</span>
</div>
</div>
<div class="landmark-info" id="romanian-athenaeum-info">
<div class="info-landmark section">
<span class="landmark-title">The Romanian Athenaeum</span>
<span class="landmark-coord">44.4413°N 26.0973°E</span>
</div>
</div>
Assuming you're not able to modify your HTML markup (in which case with use of CSS classes would be cleaner), a solution to your question would be as shown below:
// Assign same click handler to all buttons
$("#arch-of-triumph-button, #romanian-athenaeum-button, #palace-of-parliament-button")
.click(function() {
// Extract id of clicked button
const id = $(this).attr("id");
// Obtain corresponding info selector from clicked button id by replacing
// last occurrence of "button" pattern with info.
const infoSelector = "#" + id.replace(/button$/gi, "info");
// Add active-info class to selected info element
$(infoSelector).addClass("active-info");
});
Because each .landmark-button looks to be in the same order as its related .landmark-info, you can put both collections into an array, and then when one is clicked, just find the element with the same index in the other array:
const buttons = [...$('.landmark-button')];
const infos = [...$('.landmark-info')];
$(".landmark-button").click(function() {
const i = buttons.indexOf(this);
$(infos[i]).addClass('active-info');
});
This does not rely on IDs at all - feel free to completely remove those from your HTML to declutter, because they don't serve any purpose now that they aren't being used as selectors.
Live snippet:
const buttons = [...$('.landmark-button')];
const infos = [...$('.landmark-info')];
$(".landmark-button").click(function() {
const i = buttons.indexOf(this);
$(infos[i]).addClass('active-info');
});
.active-info {
background-color: yellow;
}

<span class="landmark-title">The Romanian Athenaeum</span>
<span class="landmark-coord">44.4413°N 26.0973°E</span>
</div>
</div>
Older answer, without knowing the HTML: You can extract the ID of the clicked button, slice off the button part of it, and then select it concatenated with -info:
$(".landmark-button").click(function() {
const infoSel = this.id.slice(0, this.id.length - 6) + 'info';
$(infoSel).addClass('active-info');
});
A much more elegant solution would probably be possible given the HTML, though.

Jquery .clone() only works once

I'm building a menu ordering app where I have to use Jquery.
I'm using the clone() method to duplicate cart items with the necessary data ejected in. It works once, and then logs and empty object with a <prototype>.
What I am cloning is a section in my HTML I am using as a template with an id to keep it hidden. I remove this on the cloned items.
The ejecting of the data I have excluded as it is working fine and the functions are in other files, but I am open to the idea of them being the cause.
HTML:
<div class="cart-item" id="cartitem-template">
<div class="left">
<div class="image"></div>
<div class="price"></div>
</div>
<div class="mid">
<div class="name">
</div>
<div class="stars">
<span></span>
</div>
<div class="underline"></div>
<div class="toggleReviews">
<span></span>
</div>
</div>
<div class="right">
<div class="remove-cart-item">✕</div>
</div>
</div>
</div>
The JS function:
buildCartItem = function(menuItem) {
const template = $("#cartitem-template")
template
.removeAttr("id")
.clone(false)
const newCartItem = template
newCartItem.insertAfter(".cart-item")
console.log(newCartItem)
//Get object and index atts from clicked menu item
//Also set that same data into the dom of the cart item
//As well as set that data to local storage
...
// Apply data to the cloned cart item template
newCartItem.find(".image").css("background-image", "url(" + data.image + ")")
setData(".price", "$"+data.price, newCartItem)
...
}
$(".menu-item").click(function() {
buildCartItem($(this))
})
I'm I using .clone() correctly? Honestly stuck
You are removing the attribute "id" from the source element even before cloning, That's why in the subsequent method invocations it could not find an element with the id "cartitem-template". So in your method buildCartItem, remove "id" after cloning.
const newCartItem = template.clone(false).removeAttr("id");
var buildCartItem = function(menuItem) {
const newCartItem = $("#cartitem-template").clone(false).removeAttr("id");
//newCartItem.find(".image").css("background-image", "url(" + data.image + ")");
//setData(".price", "$" + data.price, newCartItem);
newCartItem.insertAfter("#cartitem-template");
}
$(".menu-item").click(function() {
buildCartItem($(this))
})
#cartitem-template {
display: none;
}
<script src="https://cdnjs.cloudflare.com/ajax/libs/jquery/3.3.1/jquery.min.js"></script>
<div class="cart-item" id="cartitem-template">
<div class="left">
<div class="image">image</div>
<div class="price">price</div>
</div>
<div class="mid">
<div class="name">name
</div>
<div class="stars">
<span>0</span>
</div>
<div class="underline"></div>
<div class="toggleReviews">
<span></span>
</div>
</div>
<div class="right">
<div class="remove-cart-item">✕</div>
</div>
</div>
<button class="menu-item">Clone</button>
i had similar problem and i solved using function:
function getClone(){
return $(myCloningDiv).clone()
}

jQuery to iterate through class elements, grab text, insert elsewhere

I need to programmatically extract titles within a webpage, inject anchor links right above those titles and then inject navigation links near the top of the page that will link to those anchors within the same page.
I need jQuery to select all headings with the class of 'iphorm-group-title’ and extract the text.
Above each heading, excluding the first heading, an anchor tag needs to be injected so that a visitor can link to that section of the page.
The text of each heading, excluding the first heading, needs to be injected before the first heading and linked to all the anchor tags that were injected in the previous step.
This form is generated by a plugin or I would just edit the HTML.
For reference, the page is located at:
http://mountpleasantmagazine.com/BestOfBallot/
Here is an example of the HTML as of now.
<div>
<div>
<div class="iphorm-group-title">VOTER INFO</div>
</div>
<div>
<div class="iphorm-group-title">SHOPPING & GOODS</div>
</div>
<div>
<div class="iphorm-group-title">FOOD & DRINK</div>
</div>
<div>
<div class="iphorm-group-title">ENTERTAINMENT & LEISURE</div>
</div>
</div>
Here is some JS that will grab the elements and loop through the text, which is the point where I'm stuck.
jQuery('.iphorm-group-title').each(function () {
console.log(jQuery(this).text());
});
Here is how the HTML is expected to look after injecting the code.
<div>
<div>
SHOPPING & GOODS | FOOD & DRINK | <a href="#entertainmentleisure">ENTERTAINMENT & LEISURE</ a>
</div>
<div>
<div class="iphorm-group-title">VOTER INFO</div>
</div>
<div>
<a name="shoppinggoods"></a>
<div class="iphorm-group-title">SHOPPING & GOODS</div>
</div>
<div>
<a name="fooddrink"></a>
<div class="iphorm-group-title">FOOD & DRINK</div>
</div>
<div>
<a name="entertainmentleisure"></a>
<div class="iphorm-group-title">ENTERTAINMENT & LEISURE</div>
</div>
</div>
I just made a code snippet for you hope so it's the exact what you needed.
var listElement=jQuery("<div id='menuList'></div>").insertBefore(".iphorm-elements");
jQuery(".iphorm-elements .iphorm-group-wrap:not(:first-child)")
.each(function() {
if (jQuery(this)
.not(".iphorm-group-wrap:first")) {
var heading = jQuery(this)
.find(".iphorm-group-title");
var headingName = heading.text()
.split(' ')
.join('')
.replace('&', '');
var lowerHeading = headingName.toLowerCase();
var anchorUrl = [lowerHeading.slice(0, 0), lowerHeading.slice(0)].join('');
var anchorText = heading.text();
var anchorLink=jQuery('<a name="' + anchorUrl + '"></a>')
.insertBefore(heading);
var anchorLink2=jQuery('' + anchorText + '' +"<span> | </span>")
.insertBefore(heading);
jQuery(listElement).append(anchorLink2);
}
});
jQuery("#menuList span:last-child").remove();

open block on div click from list of div's in HTML

<div class="lsiting-main">
<div class="row">
<div class="col-md-8">
<div class="col-md-4 text-right">
<span class="close-list">
<span class="funded-list">

</div>
</div>
<div class="thelanguage" contentindex="0c" style="display: none;">

<div class="big-listing-details">
</div>
<hr>
</div>
<div class="lsiting-main">

</div>
<div class="lsiting-main">

</div>
I have list of class="listing-main" and i try to open block class="thelanguage" style="display: none;" on click of class="technology closedlanguage".
But what i need, when i click on class="technology closedlanguage" at that time class change "closedlanguage" to "openlanguage" and style change 'none' to 'block'.
But when i click, only one block open at that time from list of div's
<script type="text/javascript">
$(document).ready(function () {
$('.lsiting-main .closedlanguage').click(function (event) {
event.preventDefault();
var target = $('.thelanguage');
$(target).toggleClass('hidden show');
$('.thelanguage').css('display', 'block');
})
});
I have updated the HTML a bit and also if your willing to use JavaScript then refer the below code, it is working as per your expectation.
Here is the JSFiddle Link: Working JS Fiddle Link
JS Code is :
<script>
document.getElementById("technologyclosedlanguage").addEventListener("click", myFunction);
function myFunction(){
var thelanguage = document.getElementById("thelanguage");
var technology = document.getElementById("technologyclosedlanguage");
thelanguage.style.display="block";
technology.className = "technologyopenlanguage";
alert(technology.className); //class name changed.
}
</script>
HTML Code is :
<div class="lsiting-main">
<div class="row">
<div class="col-md-8">
<div class="col-md-4 text-right">
<span class="close-list">
<span class="funded-list">
<span class="new-list">
<div class="technologyclosedlanguage" id="technologyclosedlanguage" headerindex="0h">
<span class="accordprefix"> </span>
View Detail Notice
<span class="accordsuffix"></span>
</div>
</div>
</div>
<div class="thelanguage" id="thelanguage" contentindex="0c" style="display: none;">
<div align="center">
<div class="big-listing-details">
The Language
</div>
<hr>
</div>
<div class="lsiting-main">
......
</div>
<div class="lsiting-main">
......
</div>
Let me know if it works, and helps you. Happy Coding.
Change your script to:
<script type="text/javascript">
$(document).ready(function () {
$(".closedlanguage").click(function (event) {
var target = $(".thelanguage");
$(target).toggleClass("hidden");
$(".hidden").css("display", "none");
event.preventDefault();
});
