I would like to find all elements which contains title on page and add new attribute to all of them.
Example:
<div title='something 1'></div>
<p>Test<div title='something 2'></div></p>
<div>
<div>
<div>
<div title='something 3'></div>
</div>
</div>
</div>
How it should look like after page load:
<div title='something 1' rel='tooltip'></div>
<p>Test<div title='something 2' rel='tooltip'></div></p>
<div>
<div>
<div>
<div title='something 3' rel='tooltip'></div>
</div>
</div>
</div>
Previously I did it manually which is bad solution for me
$('#collection_map > div > div > button').attr('rel', 'tooltip');
Try this code:-
$('div[title]').each(function() {
$(this).attr('rel', 'tooltip');
});
You don't even need jQuery for this. Here is a working example in plain JavaScript.
var elems = document.querySelectorAll('[title]')
elems.forEach(elem => elem.setAttribute('rel', 'tooltip'))
<div title='something 1'></div>
<p>Test<div title='something 2'></div></p>
<div>
<div>
<div>
<div title='something 3'></div>
</div>
</div>
</div>
Get all elements which have attribute title and then loop over it to add new attribute rel to each object.
paragraph tag cannot have block elements like div nested in it. See - https://developer.mozilla.org/en-US/docs/Web/HTML/Element/p
Paragraphs are block-level elements, and notably will automatically
close if another block-level element is parsed before the closing </p>
tag.
$('[title]').attr('rel', 'tooltip');
<script src="https://cdnjs.cloudflare.com/ajax/libs/jquery/3.3.1/jquery.min.js"></script>
<div title='something 1'></div>
<p>Test
<div title='something 2'></div>
</p>
<div>
<div>
<div>
<div title='something 3'></div>
</div>
</div>

with :last child i can't reach so deep into the tree.
The selector div:(not(:has(div)) will match any DIV that doesn't have another DIV nested inside it.
:has(selector) matches an element whose contents include an element that matches selector. Putting this in :not() reverses the condition.
This is a relatively new CSS selector, and it's not yet supported by Firefox as of version 108. See the compatibility table.
div:not(:has(div)) {
color: red;
}

How to read text "LE 88" from the following HTML using Javascript. the text LE is not constant, it keeps on changing. It neither contains ID's, nor class names.
<body>
<div id="Record">
<div>
<div>Grade A </div>
</div>
<div>19-04-2022
</div>
<div>
<div>Subject H1
</div>
<div>
<div>LE 88
</div>
</div>
</div>
<div>
</div>
</div>
</body>
You can iterate the dom div and check for the children. In this case the div with text does not have any child. So use children and check for the textContent. If the matching text is found do the required operation
document.querySelectorAll('div').forEach((curr) => {
const child = curr.children;
if (child.length === 0 && curr.textContent.trim() === 'Marks 88') {
curr.textContent = 'Marks 88 changed'
}
})
<div>
<div>
<div>Grade A </div>
</div>
<div>19-04-2022</div>
<div>
<div>Subject H1</div>
<div>
<div>Marks 88</div>
</div>
</div>

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">

.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">
<div class="blog-header">
<div class="blog-post-container">

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);
});

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();

The content of the divs is going to be populated with javascript json. Now, I know how to select a div in javascript:
var hsc = document.getElementByID("hsc");
But how would I refer to eg. the title but only in the hsc div.
<div id="hsc">
<div id="title"></div>
<div id="jobs"></div>
...
</div>
<div id="cc">
<div id="title"></div
<div id="jobs"></div>
</div>
On a separate note, wouldn't 'title' and 'jobs' be better classified as classes, and not ids?
This would work:
var hsc = document.querySelectorAll("#hsc > .title");
But you need to change to valid html and use unique IDs and classes instead:
<div id="hsc">
<div class="title"></div>
<div class="jobs"></div>
...
</div>
<div id="cc">
<div class="title"></div>
<div class="jobs"></div>
</div>
IDs must be unique in HTML.
Change them to classes, and then you can use querySelector() to target them:
document.querySelector('.hsc .title').style.color= 'blue';
document.querySelector('.cc .title').style.color= 'red';
<div class="hsc">
<div class="title">Make me blue!</div>
<div class="jobs">Jobs</div>
</div>
<div class="cc">
<div class="title">Make me red!</div>
<div class="jobs">More jobs</div>
</div>
Just try
<div id="hsc">
<div id="a" class="title"></div>
<div id="b" class="jobs"></div>
...
</div>
<div id="cc">
<div id="c" class="title"></div
<div id="d"class="jobs"></div>
</div>
Because your HTML code is invalid because the id is already taken.
