      Guidelines and Netiquette   03/28/2017

      Posting Problems:   Having problems posting your topic? Read through this: To join, you agree to our terms and conditions and fill out and submit a registration form. An activation email will be sent to your email adress, so you'll need to verify your account. After that the account has to be validated by one of the moderators. This will mean that it can take up to a day to be activated. A couple of things to remember to ensure approval: Don't use an email address in one of those $2 four character .com domains eg. xyds.com. These will be deleted and the domain added to the banned list. Don't use an email address that is within a domain with a bad reputation for spam. A Google search is run on every email address and email domain. Don't sign up with an email address that doesn't exist, doesn't work or requires the sender to answer a quiz before their email can get to you. Put your country and or state and city in the signup form. Blank forms will go to the botton of the "to do" list. And make sure that your email address and your country match, saying you're from Alabama and using a .ru email address is not going to get you activated. After a membership is activated the first few posts will be monitored. Posting spam or unapproved topics described in the agreement results in an immediate ban. The email provider and the IP addresses associated with the account will be banned and all posts will be deleted. These strict measures have been deemed necessary to hinder spam. Sorry for any inconvenience this causes, but it's not liable to change. If, after reading this, you still can't post and don't understand why, contact one of the Moderators listed here.   Topic Guidelines   Including the following information can expedite an accurate response from board members: Must be a Specific Problem or Question related to web design and development Include Code in Question (wrap with   for small blocks of code and for longer blocks   ) Include Code Author Include Extra Notes/Modifications/Attempts Include web link to page/file when possible Content Guidelines   You may not post, upload, link to, or email any Content that contains, promotes, gives instruction about, or provides prohibited Content. Prohibited Content includes any Content that breaks any local, state, county, national or international law. Prohibited Content also includes: No direct or indirect advertising or websites, forums, products, services No hijacking of posts (do not post your question in someone elses) Content that infringes upon any rights [ex.

To get the full list, click "BB Code Help" underneath the clickable smilie face menu. Use   for small snippets of code Use   for lengthy snippets of code Use   if your snippet is HTML (optional) Use   if your snippet is SQL (optional) Rules of Conduct   Be nice. There's no need for calling someone stupid if they ask an 'easy' question. Keep your avatars and signatures absolutely child friendly. We have a younger audience on this forum. Keep your language appropriate for the same reason above. Do not PM moderators for help on the forum. Post on the topic, or create a new one.   Spam:   Recently, as you have all without doubt noticed, we have had lots of spam and advertisement on the forum. Therefore, we'd like to alert you as to what to do when you have found any of the aforementioned annoying messages: it. Immediately. Give a clear reason, please, if the advertising is not evident. DO NOT POST! Report, let the post stay as is, and we will get to it, meanwhile if you continue to post as normal in the other threads, it won't be on the top so long. Refrain from PMing the member. This won't help at all, as they are most likely spambots anyway. Thank you.       Images in signatures:   After thinking of users on dial-up, we have decided to enforce the following rules regarding signatures. Please pay heed to them. Respecting these rules is respecting the members on this forum with dial-up. Signature rules: No animated images AT ALL. No matter the amount of animation. Maximum image widthxheight: 300x150 Maximum image (file) size: 15kb Use calm colors. Do not use highly contrasting images in your signature, as this can get really annoying when seeing several posts from one member in the same thread. The same prohibited content goes for images as for posts. Lastly, use common sense. No lengthy signatures please. Save us some scrolling. Thank you.       Links in signatures:   Please understand that w3schools.com only exists because of voluntary work and is barely supported by the advertising littered throughout the tutorials and the forum. So, please, stop advertising other sites. DO not post links that drive traffic away from the w3schools domain - especially to a site that offers similar if not identical information. Please help support the site by keeping individuals on it. Thank you. Here are some guidelines as to what you can put in your signature: w3schools links --> allowed w3.org links --> allowed browser links --> allowed html editor links --> allowed personal sites --> allowed tutorial sites competing with w3schools --> NOT allowed sites completely irrelevant to webprogramming and this forum --> NOT allowed   Thanks for understanding, and for taking the time to read this. ~W3Schools Modstaff~

Multiple Select List - Order of Results and Repeat Searches.

Recommended Posts

Techno Kid    0

Hi.

I am familiar with some HTML but my knowledge in Javascript, JQuery and CSS is very limited. I have been learning from examples on the web and making my own changes. Please see the fiddle I am working on below; sorry if the full code is messy!

https://jsfiddle.net/djj2c84t/

There are a number of features I wish to implement but I am totally stumped! I have gotten as far as I think I can with the fiddle above and it would be more than appreciated if anyone can provide any help, possibly with any example code and where the code needs to go.

When I make a multiple selection from the list, how do I get the results (divs) to show in order of most recent selection at the top? For example, if I multi-selected in the order Nuts, Meats, Vegetables, Fruits, how do I get the results (divs) to appear in the order Fruits, Vegetables, Meats, Nuts? At the moment they appear in the order that they are listed in the box.

I would also like to ask if it is possible to keep the results (divs) showing for all the items selected even after a new search is performed and a new selection made. For example, if I search for 'F' and select 'Fruits' and then search for 'V' and select 'Vegetables', can I have both the 'Vegetables' and 'Fruits' divs showing in the results? At the moment, 'Vegetables' replaces 'Fruits'. If this is possible, would it also be possible to have the selected items in the list remain highlighted even after a new search is performed? For example, after making the above searches/selections, if I then search for 'ts', the list would show 'Fruits', 'Nuts' and 'Meats', but I would like 'Fruits' to still be highlighted and to be able to close the 'Fruits' div by de-selecting 'Fruits' from the list or clicking the Close (X) button on the 'Fruits' div itself.

There are a few other things I have not been able to solve but I will refrain from posting too many questions at once.

Any help would be greatly appreciated!

Thank you.

Because they show as the order they are laid out from the beginning. There are several ways to do this, but will involve cloning the current hidden divs, in the order they were selected, removing the original hidden selected and then appending cloned divs in correct selected order.

Thanks for your reply, dsonesuk. Sorry for my late response; have been attempting to figure out what to do with your instructions.

Please don't laugh, but are any of the following remotely close to anything I need to use in my code?

Thanks.

$(".mydivs1").clone()
removeClass('.mydivs1')
addClass('.mydivs1clone')
.prependTo("body");

First of all you can't have multiple id references, or spaces within id value, and as id must be unique within a page, you have to clone a element with unique id and temporarily apply it to variable, then remove original, then prepend temporarily cloned to a surrounding container which would make it easy to control placement and order.

But first you will need an array that will store id references, that do not currently exist, in order they were selected, then looping this array you can temp clone, remove original, prepend clone.

var SelOrderArray=[];

$.each($selected,function(i){  //loop through selected possible multiple selected options

	if(SelOrderArray.indexOf($selected[i]) === -1){  //if current looped through $selected value not in array then add to array

	SelOrderArray.push($selected[i]);

	}

});

// loop through ordered array of slected options
$.each(SelOrderArray,function(i){  

//clone element with specific id to temp storage variable
	var TmpDivClone = $("#"+SelOrderArray[i]).clone(); 

//remove current existing element with specific id
	$("#"+SelOrderArray[i]).remove(); 

// prepend temp cloned element to div #result wrapping mydiv1 elements so prepending remains below dropdown and show
	TmpDivClone.prependTo('#result').show();

});

Hi dsonesuk.

Thank you for taking the time to write this for me; I really appreciate it! There is absolutely NO WAY I would've learnt what you have written in the time I need to have the code ready by! This has just been a one-off project and I have just been managing by manipulating existing examples, etc. I haven't had much time to start to 'learn' JS/JQuery, which you have probably guessed from my questions!

Anyhow, have you managed to test the code? I have copied and pasted it in various places within the existing code but nothing is happening. There is not likely to be anything wrong with your code, but my lack of knowledge of where it is supposed to be placed!

Do I need to replace any of the text in your code with text specific to my data?

Thanks.

Thanks again, dsonesuk!

The code will be used on IE and Chrome, however, I am using an old version of FF at present and and won't be able to test on IE/Chrome until I can access them in a few days.

Anyhow, in the meantime, what is happening at my end is:

-The items are showing up in the order I wish them to (most recent at top), however, if I click an item, then deselect it and then select another item, both items appear. I also cannot then deselect just one of them, if I click the first one selected, nothing happens (the item still remains) and if I click the second (last) one selected, both items get deselected (disappear).

-The filter as you type isn't working.

-There are no gaps between each result div.

As mentioned, I'm not sure how much of the above is to do with my old browser. May I ask which browser and version you are using?

Thanks.

Then you would have to make tmp duplicate array, of the array of ordered selected items, loop though selected items from dropdown and if identical remove, you should end up with last item deselected. Then remove this item from original array of selected items. Use .indexOf() to find matching values.
