Wrapping a jquery validate span.error with nested divs - javascript

Heyo. This is my first stack overflow post because I am stumped and not finding many people who are trying to accomplish the same thing. I've tried using jquery .before(), .after(), and .wrap() to resolve this. I was initially using css :before and :after pseudo-elements, but as that won't work for legacy browsers, I've decided to use jquery.
I already have several forms on several pages with validation working. The error messages vary in length. We were using a static, one size background image on the default span element, so content was bleeding out on longer error messages. I built a flexible rounded corner series of nested divs to allow the error box to grow or shrink dynamically. The html I want to output is:
<div class="errorWrap">
<div class="errorTop"><span></span></div>
<div class="errorContent">
<span class="error">This is an error</span>
</div>
<div class="errorBottom"><span></span></div>
</div>
Here's an example of a solution I tried, but I'm still pretty new to javascript.
$('.error').before('<div class="errorWrap"><div class="errorTop"><span></span></div><div class="errorContent">');
$('.error').after('</div><div class="errorBottom"><span></span></div></div>');
Correct me if I'm wrong, but I think that I have the right idea with the jquery. But it's just kind of sitting there, not in any function being called. So I imagine that since the code isn't re-executing, it just doesn't show up. Is there an appropriate function to wrap this in? I'm certain I'm just not attacking this from the right direction. Any help is super appreciated.

the plugins "before" and "after" dont take html as string. you cannot start a div in one and close it in an other.
Either you take your current html and generate a new html string which you append where you want to or you use the "wrap" plugin http://api.jquery.com/wrap/
Using pure HTML
$(".error").html("<div class='beforeContent'>" + $(".error").html() + "</div>");
Using wrap (http://api.jquery.com/wrap/)
$(".error").wrap("<div class='beforeAndAfter'></div>");

If you want to show an error div after focus out of an input then you have to create it using html/wrap as Luke said and then you have to append it in ot the dom useing
$('.errorWrap').insertAfter('.focusedElement');
But there are other methods available to insert a new element like append/appendTo e.t.c,

I ended up fixing this problem on my own using jquery to create the div and it's nesting on pageload, the divs are generated with an error class that gives display:none. A custom errorPlacement function nests the error in the correct div. Then I used a custom validator highlight function to remove the class that hides the element. Then I used the unhighlight function to re-add the class to re-hide the div.
$(function() {
//Generate the elements and assign attributes
var errorWrap = document.createElement('div');
$(errorWrap).addClass('errorWrap hideError');
var errorTop = document.createElement('div');
$(errorTop).addClass('errorTop');
var topSpan = document.createElement('span');
var errorContent = document.createElement('div');
$(errorContent).addClass('errorContent');
var errorBottom = document.createElement('div');
$(errorBottom).addClass('errorBottom');
var bottomSpan = document.createElement('span');
//Place the elements directly after each dd element
$("dl > dd").append(errorWrap);
$("div.errorWrap").append(errorTop)
.append(errorContent)
.append(errorBottom);
$("div.errorTop").append(topSpan);
$("div.errorBottom").append(bottomSpan);
//Add custom validator defaults
$.validator.setDefaults({
errorPlacement: function(error, element) {
$(element).nextAll('.errorWrap').children('.errorContent').append(error);
},
highlight: function(element) {
$(element).nextAll('.errorWrap').removeClass('hideError');
},
unhighlight: function(element) {
$(element).nextAll('.errorWrap').addClass('hideError');
}
});
}
Although I'm sure this could have been done more shorthand, I really like this technique because I didn't have to update any of my pages that contained forms to get it to work. All of the nested divs are dynamically created by javascript, so I can include a global file to any page with forms and it will just work. Thanks for all who offered suggestions.

Creating dynamic divs

Trying to make a dynamic div but i don't know how. Wrote a solidity smart contract that accepts an array of struct. In the smart contract i can use a get function to display the data inside. Data in the array is treated like a history, it consists of amount (making a crowdfund site), date, currency used, etc. Since the get function in the smart contract can only extract one part of the array, i thought of putting the get function into the while loop and extract the whole history array..
<div id=set>
<a>value1</a>
<a>value2</a>
</div>
I'm trying to dynamically create another div with the same amount of < a > in the div. If i had 10 sets of data to display in that div, i wish to create only 10 sets of that div. Can createElement() be used to do that? Couldn't find any solution that works. Totally have no idea on how to create it. Can someone please help.
Would it be rational to extract the data from the array using a while loop and putting it in a div to display or would it use too much gas for this to work?
I don't get why would you want to do this, but you can do like this:
$('#set a').each(function(){
$('#set').after( "<div></div>");
});
It selects all of the <a>...</a> inside the <div id="set">...</div> element, and for each one of those inserts a <div></div> element. It inserts the element right next to #set but you can change that to any other element you could select.
I'm supplying jQuery code since you tagged the question as jQuery.
Hope it helps,
You can get the number of anchor tags by using this function getElementsByTagName('a').length from the hosting div. Then use that number to create new divs. This solution is done using vanilla JS.
function createDynamicDivs(){
var newDiv = document.createElement("div");
var noOfAnchors = document.getElementById('set').getElementsByTagName('a').length;
for(var i=0;i<noOfAnchors;i++){
var newContent = document.createElement("a");
newContent.textContent= "Test ";
newDiv.appendChild(newContent);
}
document.getElementById('new').appendChild(newDiv);
}
<div id=set>
<a>value1</a>
<a>value2</a>
</div>
<div id="new"></div>
<button onclick="createDynamicDivs()">Generate</button>

Issue with tree traversal, finding div ID to be used variably - jquery

so I've been trying to figure this out but I'm coming up short. Have really tried searching the best I could to come up with the answer, including jQuery API documentation and other SO posts. I feel like I'm almost there but I'm either misunderstanding something or I'm approaching this goal incorrectly.
For multiple different sections, I have 2 clickable icons in separate div's, 1 (lets say iconA) shown on load and 1 hidden (iconB) on load. When (iconA) is clicked, it hides the [sectionA] where (iconA) is located then shows the [sectionB] where (iconB) is located. I then want (iconB) to hide [sectionB] and show [sectionA].
Clearly I can't use toggle because one of the sections is always hidden at any given point. And since I'm trying to write a script that I can use for multiple sections and multiple icons, with different names, I can't just set 1-1 class names for ALL icons and sections.
I've created a jsfiddle to illustrate. Below I'll write a quick example.
HTML:
<div class="sectionAparent>
<div class="sectionA" id="example>
<i class="fa fa-code contbtn">iconA (shown on load)</i>
</div>
</div
<div class="sectionB" id="exampleSHOW">
<i class="fa fa-minus minushide">iconB (hidden on load)</i>
</div>
jQuery:
$('.contbtn').click(function(){
var contid = $(this).attr('id');
$('#'+contid+'show').slideToggle(1000);
$(this).hide(1000);
});
-this first one is to hide sectionA and show sectionB, which works fine.
$('.minushide').click(function(){
var cbtn = $(this).closest('.sectionB').siblings('.sectionAparent').find('div[id]');
var cid = $(cbtn).attr('id')
$('#'+cid+'show').slideUp(1000);
$(cid).slideDown(1000);
});
-So my thoughts were to jump up to the closest ancestor that is a sibling to the section containing the ID that I need. Then find the div with that ID, retrieve that ID, and use it show the section containing the ID and hiding the section with the ID+more. The goal is for this to be variable for multiple different sections with similar naming conventions without having to hard-code the section names in a list inside my script.
Hope this makes sense and I apologize for the wall of text, just wanted to make sure I conveyed what I'm trying to do and where I'm at. If my logic is incorrect or there is an easier way to do this, then I'm all ears! Thanks.

You forgot to append the '#' character to sid in the second last line of the js
Updated fiddle
$('#'+sid).slideDown(2000);
Since you are using class (sectionhide) to toggle visibility, you can look into .toggleClass method.
It has an overriden constructor to accept 2 arguments, className and state (a boolean value)
Based on this state, it will add/remove class. True means add and false means remove
$('.minushide, .contbtn').on("click", function() {
var container = $(this).closest('.container');
var nextContainer = container.next('.container').length > 0 ? container.next('.container') : container.prev('.container');
container.toggleClass('sectionhide', true)
nextContainer.toggleClass('sectionhide', false)
})
Sample Fiddle
Note: I have added a common class container to both divs to have a common pattern
For a carousel kind of behaviour, you can use index to find index of element to be shown and hide all.

jQuery: inserting text into container div on hover

I'm using a simple jQuery image slider (Owl Carousel) to show a list of speakers at a convention with photos, and I'm trying to find a way to overlay text associated with each speaker onto a div placed above the slider. I have a mockup page here. As you can see on the mockup, I have two primary divs-- i.e. div#sit and div#carousel-sit; within the former I have an container with the class .sit-quote-container into which I'd like the quote text/markup injected. I would like this overlay text to pull from the paragraph elements with the .sit-quote class that exist for each speaker.
In addition to the problem of displaying the appropriate text within the container div, I'm seeing that placing the .sit-quote paragraph within each slide is causing a gap to appear under the speaker name (the grey box underneath) and I have no idea why this is happening given that I've set .sit-quote to display:none. I'm wondering if perhaps I need to move the elements containing the quotations out of the slider markup altogether (?)
As for the actual hover function, this is what I have so far, with the help of another SO user; but it doesn't seem to be working:
$(".slide-sit").hover(function() {
var clone = $(this).find(".sit-quote").clone();
clone.appendTo(".sit-quote-container");
}, function(){
$(".sit-quote-container").html(""); // this clears the content on mouseout
});
Ultimately, I'd like the quotes to fade in/out positioned within the main div. Thanks for any assistance, and please let me know if I need to provide further clarification as to the aim here.
you should first visible that quote
try this:
$(".slide-sit").hover(function() {
var clone = $(this).find(".sit-quote").clone();
clone.appendTo(".sit-quote-container").show(); // Here you should show the quote
}, function(){
$(".sit-quote-container").html("");
});
if you want to fade in:
$(".slide-sit").hover(function() {
var clone = $(this).find(".sit-quote").clone();
clone.appendTo(".sit-quote-container").fadeIn(); //Here if you want to fade the quote
}, function(){
$(".sit-quote-container").html("");
});
Use the below script to pull the text from .sit-quote p tag of the hovered item and display it in the .sit-quote-container
UPDATE
If needed wrap the quote in a para tag and to avoid complexity use a different class name, in this case .sit-quote_inner.
CSS : .sit-quote_inner{ display:none; }
JS
$('.sit-carousel-container .owl-item').hover(function(){
var quote = $(this).find('.sit-quote').text(); //Only text not the p tag
quote = '<p class="sit-quote_inner">' + quote + '</p>';
$('.sit-header .sit-quote-container').html(quote);
$('.sit-quote_inner').fadeIn(); //Add this
},function(){
$('.sit-header .sit-quote-container').html('');
});
The carousel seems to be dynamically injecting clones of the slides. In this case, you might want to delegate your event handler so that it works with the dynamically generated slides.
Also, if you want to fadeOut the text, you should remove it in the complete callback of fafeOut instead of simply emptying the html Try
$(document).on("mouseenter",".slide-sit",function() {
var clone = $(this).find(".sit-quote").clone();
clone.appendTo(".sit-quote-container").fadeIn("slow");
});
$(document).on("mouseleave",".slide-sit", function(){
$(".sit-quote-container")
.find(".sit-quote")
.fadeOut("slow",function(){ // Fadeout and then remove the text
$(this).remove();
})
});
The gap (grey background) is the background of .slide-sit, which is visible due to the margin-bottom: 15px; applied on the paragraph containing name (style rule .item p main.css line 67 it seems), removing this will fix the issue.
Update
It'd be better if you keep a .slide-sit inside the .sit-quote-container so that you can fade it in/out properly using the below script.
$(document).on("mouseenter",".sit-carousel-container .slide-sit",function() {
var content = $(this).find(".sit-quote").html();
(".sit-quote-container .sit-quote").html(content).fadeIn("slow");
});
$(document).on("mouseleave",".sit-carousel-container .slide-sit", function(){
$(".sit-quote-container").find(".sit-quote").fadeOut("slow")
});

extracting text from html file

I'm trying to get nodes containing text from html file using Javascript and jQuery.
if I have a node like
`
<div>txt0
<span>txt1</span>
txt2
</div>
How can I select elements that meets this criteria??
Meaning, I need to retrieve thedivand thespan` , and it would be even better to know location of the text.
I'm trying to get the text to replace it with images in a later function.
I tried this
`
$('*').each(function(indx, elm){
var txt = $(elm).text();
// my code to replace text with images here
});
`
but it does not get the required results.. it does all the parsing in the first element, and changes the html totally.
I don't know exactly what you're trying to solve, but perhaps you can be a bit more specific with your selector?
$("div span").text(); // returns 'txt1'
$("div").text(); // returns 'txt0txt1txt2'
By adding ids and/or classes to your html, you can be very specific:
<div class="name">Aidan <span class="middlename">Geoffrey</span> Fraser</div>
...
// returns all spans with class
// "middlename" inside divs with class "name"
$("div.name span.middlename").text();
// returns the first span with class
// "middlename" inside the fourth div
// with class "name"
$("div.name[3] span.middlename[0]").text();
JQuery has pretty good documentation of these selectors.
If this doesn't help, consider explaining the problem you're trying to solve.
Your markup structure is a bit uneasy. Consider changing to something like this
<div>
<span>txt0</span>
<span>txt1</span>
<span>txt2</span>
</div>
Then using jQuery
$("div span").each(function(k,v) {
$(this).html("<img src=\""+v+".jpg\" />"); //replace with the image
});

Writing to a non-unique div with Javascript

I'm building a multi-feed RSS reader for school.
aList is the div that encompasses each individual feed (the amount of feeds will fluctuate).
theTitle is the div that will be filled with the attribute of the current feed. Additionally, if clicked, it will load a list of attributes from the current feed into theContent.
I'm wondering how I can dynamically load the attributes into theContent when theTitle is clicked, since theContent and theTitle are going to be non-unique divs (I can't give them IDs).
Thanks for your help in advance,
-Andrew
document.getElementsByClassName('aList').getElementsByTagName('div')
You should look into jQuery selectors for that and other DOM Manipulation. Something like
$("div.theContent").attr("name", "value");
by using jquery, you may use code like the following:
$(".theTitle").bind("click", function(){
$el = $(this);
$el.parent().$(".theContent").load('ajax/content.php?news=' . $el.text());
});
this will make all your links clickable, an on click, update their corresponding content divs with the value of ajax/content.php?news=theTitle-value
Use a nice Javascript library such as Prototype or jQuery. Seems petty now, but these frameworks save you tons of time in the long run.
In both frameworks, you can select that div with:
$('div.theTitle')
With jQuery, you can do:
$('div.theTitle').click( function() {
var title = $(this).text();
var contentDiv = $(this).siblings('div.theContent');
// Do something with contentDiv and the title
} );
This will make every theTitle div have an onClick event that does something with its associated theContent div.
<div class="aList">
<div class="theTitle" onclick="fillContentBox(this)"></div>
<div class="theContent"></div>
</div>
And in your script ...
function fillContentBox(div) {
var theContentDiv = div.parentNode.getElementsByTagName("div")[1];
// statements that do things with theContentDiv
}
You have to be able to determine which element you want to update if you don't want to update more than one. If the elements are grouped inside something else that does have an "id" value, you can take advantage of that.
