How to copy the href link of an anchor to other anchor?

I am showing a set of products via shortcode in WordPress. The display has an image and button.
Problem: Only the photo contains the link to single product page. The associated button does not have the link to the single product page.
This is the current code:
<div class="display-products">
<div class="wpb_wrapper">
<div class="displayProduct-shortcode displayProduct-Container">
<div class="product_grid dp-section dp-group woocommerce" id="displayProduct">
<div class="dp_product_item dp-col dp-col_1_of_6 firstcol">
<div class="dp_images">
<a class="dp-product-image" title="Custom Made Wedding Cabinet" href="yahoo.com">
<div class="he-wrap tpl1">
<div class="dp-img-wrapper"> <img width="192" height="264" alt="#" class="attachment-display_product_thumbnail size-display_product_thumbnail wp-post-image" src="img_src"> </div>
</div> <span data-id="696" class="dpquickview dp_quickview_button"><img src="img_src"></span> </a>
</div>
<div class="dp-product-information clearfix">
<h2 class="product-name">
<a title="Custom Made Wedding Cabinet" href="#">Custom Made Wedding Cabinet</a>
</h2>
<div class="dp-stock"></div>
<div class="dp-grid-button"> <a class="single_add_to_cart_button button alt db_customButton" href="#">READ MORE</a> </div>
<div style="clear: both;"></div>
</div>
</div>
</div>
</div>
</div>
</div>
Desired Output: I want to somehow iterate over each .single_add_to_cart_button and copy the link of every product-name to each READ MORE button
This is my current jquery code:
j('.display-products .displayProduct-shortcode .dp-product-information .dp-grid-button .single_add_to_cart_button').each(function() {
var getProductLink = j('.display-products .displayProduct-shortcode .dp-product-information .product-name > a').attr('href');
j(this).attr('href', getProductLink);
});

Set the href attribute value using the elements context. Use closest() to traverse up to dp-product-information element then find the desired anchor element the read its attribute and set the value.
Use
j('.display-products .displayProduct-shortcode .dp-product-information .dp-grid-button .single_add_to_cart_button').attr('href', function(){
return j(this).closest('.dp-product-information').find('.product-name>a').attr('href');
});
$(function() {
$('.dp-product-information .dp-grid-button .single_add_to_cart_button').attr('href', function() {
return $(this).closest('.dp-product-information').find('.product-name > a').attr('href');
});
});
<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script>
<div class="dp-product-information clearfix">
<h2 class="product-name">
<a title="Custom Made Wedding Cabinet" href="#Test">Custom Made Wedding Cabinet</a>
</h2>
<div class="dp-stock"></div>
<div class="dp-grid-button">
<a class="single_add_to_cart_button button alt db_customButton" href="#">READ MORE</a>
</div>
<div style="clear: both;"></div>
</div>

Instead of assigning value for the different buttons with the links I would like to suggest you to use a common class (if you can) then trigger the click event for them:
$('.selector').on('click',function(){
$('.a-selector').trigger('click');
});

Change span text on a click

I have a link with image
<div class="va-pickers">
<a class="va-picker" data-attribute="pa_Attribute">
<img class="va-picker-item" src="img.jpeg">
</a>
</div>
And I want to change span text ( change it ) on link click
<ul class="gform" id="gform_1">
<li id="field_1">
<div class="ginput_container">
<div class="medium" id="s2id_input_1_2">
<a class="select2-choice">
<span class="select2-chosen" id="select27">change it</span>
</a>
</div>
</div>
</li>
</ul>
I try
$(document).ready(function(){
$("a[data-attribute='pa_Attribute']").click(function(){
$('#gform_1').find('span').text('my_text');
});
});
But it doesn`t work
Thanks

Your code works find. Check in your console to see if nothing is missing (JQuery maybe). Here's your working fiddle.

jquery: how to append DOM element to selector within variable containing other DOM elements

When storing DOM elements in a javascript variable prior to appending them to the actual DOM is there a way with jQuery to select elements inside the variable?
For example,
I have a list of tweets on my page. Every time I click a refresh button I append a new tweet to the list below.
I add the new tweet like follows:
new tweet
<li class="tweet normal-tweet" data-user-name="Dorothy">
<div class="image">
<img height="48" width="48" src="http://twitter.com/api/users/profile_image?screen_name=Dorothy" alt="" />
</div>
<div class="content">
<div class="user">
<a class="user-name" href="http://twitter.com/Dorothy" title="Dorothy">Dorothy</a>
<div class="full-name"></div>
</div>
<div class="text">Once in a lullaby</div>
<div class="time-stamp" data-time="1322631934000">1322631934000</div>
</div>
</li>
Inside each tweet on the page, not the new tweet yet, I use jQuery to append some elements.
I have:
var actionsMarkup =
"<div class='actions'>
<span class='favorite'>Favorite</span>
<span class='retweet'>Retweet</span>
<span class='reply'>Reply</span>
</div>";
and I append it to the element with the .content class
$(actionsMarkup).appendTo('#tweets .tweet .content');
Now, when I make a new tweet I do the following:
$(document).on('click', '.refresh', function() {
newTweet = $(<new tweet code from above>);
actionsMark = $(actionsMarkup);
$(newTweet.appendTo('#tweets');
I need to be able to append the actionsMark contents to the div with class .content. However, I can't just reapply my prior statement of
$(actionsMarkup).appendTo('#tweets .tweet .content');
because that puts the markup on all .content divs again, even if it is already there.
Is there a way for me to use selectors to access the DOM nodes in my newTweet variable before I append it to the document object?
I am thinking something like
$(actionsMarkup).appendTo( newTweet, '.content');
If there is no way with selectors to do this then what are some other quick ways?
List of Tweets and Tweet container
<ul id="tweets" class="normal-tweet show-promoted-tweets">
<li class="tweet promoted-tweet" data-user-name="Dorothy">
<div class="image">
<img height="48" width="48" src="http://twitter.com/api/users/profile_image?screen_name=Dorothy" alt="" />
</div>
<div class="content">
<div class="user">
<a class="user-name" href="http://twitter.com/Dorothy" title="Dorothy">Dorothy</a>
<div class="full-name">Dorothy</div>
</div>
<div class="text">Somewhere over the rainbow</div>
<div class="time-stamp" data-time="1322631934000">3 minutes ago</div>
</div>
</li>
<li class="tweet promoted-tweet" data-user-name="lion">
<div class="image">
<img height="48" width="48" src="http://twitter.com/api/users/profile_image?screen_name=lion" alt="" />
</div>
<div class="content">
<div class="user">
<a class="user-name" href="http://twitter.com/lion" title="lion">lion</a>
<div class="full-name">Lion</div>
</div>
<div class="text">Way up high,</div>
<div class="time-stamp" data-time="1322631934000">17 minutes ago</div>
</div>
</li>
<li class="tweet normal-tweet" data-user-name="scarecrow">
<div class="image">
<img height="48" width="48" src="http://twitter.com/api/users/profile_image?screen_name=scarecrow" alt="" />
</div>
<div class="content">
<div class="user">
<a class="user-name" href="http://twitter.com/scarecrow" title="scarecrow">scarecrow</a>
<div class="full-name">Scarecrow</div>
</div>
<div class="text">And the dreams that you dreamed of,</div>
<div class="time-stamp" data-time="1322631934000">32 minutes ago</div>
</div>
</li>
</ul>

You can use .last(), to select the last element after you append your new tweet, like below:
$(document).on('click', '.refresh', function() {
newTweet = $(<new tweet code from above>);
$(newTweet).appendTo('#tweets');
var actionsMarkup =
"<div class='actions'>
<span class='favorite'>Favorite</span>
<span class='retweet'>Retweet</span>
<span class='reply'>Reply</span>
</div>";
$("#tweets .tweet").last().find(".content").append(actionsMarkup);
});
if you insist to use appendTo(), you can try using :last-child:
$(actionsMarkup).appendTo('#tweets .tweet:last-child .content');

I was looking to see if you can do the same thing, found this question but the existing answer is not useful in my case as i would like to alter the element before adding.
You can create a new dom element in a variable with jQuery and do operations on it as if it is already in the dom before appending it.
Example:
var newTweet = $('<div></div>');
newTweet.addClass('tweet');
newTweet.append('<span class="username"></span>');
newTweet.find('span.username').html('John Doe');
$('body').append(newTweet);
the following will be appended to the body:
<div class="tweet"><span class="username">John Doe</span></div>
Very handy if you are building a reusable interface element (like a dialogue box) with multiple options.

JQuery Parent-Child Selection

I am new to jQuery and am trying to write a script that will run through a menu list and display the correct background image based on the menu item. The menu list is going to be randomly populated so a script is necessary to load the correct image.
The problem is that the attribute where I am able to see which item the menu belongs to is not on the list item itself but on a div contained inside the list item. My question is is it possible to select a child element of the already selected element ?
E.g (the menuli a segment)
$(document).ready( function() {
$(menuli).each( function(index) {
$itemnumber = $(menuli a).attr("href");
switch($itemnumber) {
case 1:
$(this).css("background-image", "image01.jpg");
break;
}
});
});
This is more or less the script I am trying to get, where each list item is iterated through and depending on the href of the link inside the list item a background image is set to that list item.
EDIT
Here is my html:

Yes you can, use find
var parentElement = $('#someElement');
var childElement = parentElement.find('.child'); //where .child should be your child selector
Where as example code is not clear, I just gave answer to your question.

try to change this:
$(this).css("background-image", "image01.jpg");
to this:
$(this).children("div").css("background-image", "image01.jpg");
If you want to target the direct child of the element, better to use children() than find()
Please refer to this: What is fastest children() or find() in jQuery?

Search the document for text to remove more than the tag it's found in

Imagine you had html code like this:
<div id="2761421" class="..." data-attributionline="testtext wrote at..." data-created-at="1342689802000" data-updated-at="1342689802000" data-user-id="36847" >
<div class="subject"> <strong>
<a name="2761421" href="#2761421">wee</a></strong>
</div>
<div class="info">
<div class="author"> author:
<span class="name"> testtext (
we)
</span>
</div>
<div class="date"> date:
<time datetime="dfgdf">dfgdfg
</time>
</div>
</div>
<hr style="clear: both;" />
<div class="text gainlayout"> some text
</div>
<div class="foot gainlayout unselectable">
<span class="menuitem postmenuitem-report">
cvbcvb
</span>
</div>
</div>
What would the javascript code look like that searches the whole document for parts where the div with data-attributionline= contains testtext to replace the whole cited div from start to finish with "Filtered"?
or
What would the javascript code look like that searches the whole document for
<span class="name">
where the name contains testtext to replace the whole div starting from
<div id="<someid>" class="..." data-attributionline="testtext<some text>" data-created-at="<somedate>" data-updated-at="<somedate>" data-user-id="<someid>" >
to the last div, ie
</span>
</div>
</div>
with "Filtered"?

There is a whole bunch of attribute selectors (see also CSS), that will match elements with attributes that start with or contain testtext.
In javascript, you can use document.querySelector[All]() or a library function that supports those to get the elements, then remove them.
