I have a page that uses jQuery to create a number of <input> DOM elements dynamically based on what user picks from a <select> box.
Let's say the user picks 4 from the select box, my script dynamically shows 4 input boxes.
The problem is when the user refreshes or goes back to this page (with the browser back button). The elements that are created dynamically are not repopulated to their last values, while all the other 'static' elements are.
I was thinking I could create a hidden input that would be serialized through javascript with the contents of the dynamic boxes, then read from it on $document.ready and then repopulate my boxes.
Is there a better way?
legenden - there are a number of possible solutions to this, I would check out these history plugins for one:
History Remote
jQuery History plugin
Deep Linking plugin
They are a little fidgety, but you should be able to hack up something positive. I will also add, that this can probably be done by storing the dynamically elements in a cookie(s) and somehow repopulating. Check out the jQuery Cookie plugin. Hope that helped you get started.
You need to manage history yourself if you want things to work in this way. You need Really Simple History.

I'm building a website using the ACF plugin (Version 5 Pro), and I'm setting up a button on a page template, which by itself isn't the problem. The problem is that depending on the specific content of each individual page using that template, the button can have one of several different appearances. What I'm trying to do is set things up so that I can upload all the buttons into the default value section of the ACF field ahead of time, and then every time I make a new page using that template, simply select the appropriate button from a radio button, a dropdown menu, or something similar on the backend of the page. I plan to be constantly uploading small amounts of content using this template, so not having to manually select the appropriate images on each page would save me a lot of time.
I've googled around and there wasn't a good answer I could find anywhere, so I'm hoping one of you more knowledgeable folks could help me out!
(And before anyone proposes this as a solution, no, the content of each page isn't something I can define just using programming. It's a little more abstract and needs human input. If all else fails I can just make multiple templates and simply select the appropriate one when I go to make a page, but the way I'm trying to do it now would be a lot cleaner).
You can try ACF Flexible Content:
https://www.advancedcustomfields.com/add-ons/flexible-content-field/
Using Flexible Content field, you will be able to create multiple fields (button 1, button 2, etc) including a WYSIWYG editor and build the buttons HTML adding the default value of the field.

However, I think you'll get in trouble making your buttons dynamic with this approach... so I'd suggest it will be better if you keep some parts of the buttons (like URLs) dynamic, using an extra field to enter the URL, anchor, etc.
I have a rather long form where a user has to fill in some sections and leave others blank depending on their circumstances and then I will save the sections to a database. To help visitors stay organized I have utilized jQuery UI's Accordion to divide the form into sections.
Now that the form is built I'm trying to find a way to display just the sections they filled in so they can print them off. If I simply bring up the form and they try to print it, it will print the accordion sections.
Right now I'm thinking of getting all the div's that have inputs filled in, combining them, and then sending them off to the DB to be saved so I can call them up later. This seems a little sloppy to me and I would prefer something tidier and that would be considered "best practices." If anyone has a better, neater, more efficient way of doing this I would appreciate your input! Thanks!
I made something similar for my work. I gathered the fields that were actually filled in and created an overview on the same page using jQuery. Rendering this info on the client and on the same page saves you from a server/database call.
We used jQuery serialize() for fetching the filled in input fields and labels and created a JavaScript object with the values so we could render these in an overview. This overview would render in the page when clicking a check form button, then if the user is not satisfied they can go back to the form by cancel or proceed.
You might want to split it up into tasks:
Store relevant form HTML in a variable
Filter out the fields that are empty
If necessary reorder the HTML
Render the HTML for viewing and printing
I have a website with Drupal 7. On one page, we have two quicktabs (using quicktabs module), under each quicktab we have expendable fields. Those fields are expandables thanks to this code:
jQuery(".ideas-content").hide();
jQuery(".ideas-title").click(function () {
jQuery(this).toggleClass('ideas-closed').toggleClass('ideas-open').next(".ideas-content").toggle();
});
The user can click links inside these expandable fields to go to another inside page. When the user goes to the previous page (the page with these expandable fields), quicktabs are back to default and the fields the user previously expanded are not expanded anymore.
How can I do to have the user coming back on the page with the right quicktab and fields expanded? I was thinking to create anchor links but I do not know more.
I googled the issue with no success.
Thank you for any input and help.
If you are able to access the exact HTML of your page, through template.php function overrides, .tpl.php overrides, or by writing the HTML yourself within the page.tpl, you can add IDs and classes around the elements you want, and then since you are using javascript, you can try using a library such as https://github.com/browserstate/history.js in order to get functionality to take the user back to the state they were in -- with open sections -- after going to another page.
I have a ListBoxFor and the first item is All Values. I already have the list box set to allow multiple selections. I would prefer to make it so that if a user selects the All Values option they are either asked if they want to clear out all other selections (Use All Values) or keep their current selections (De-select All Values). I would be ok without the user dialog asking them what to do and just automatically clearing out selections, but that is less preferable.
At first glance it seems that Javascript/jQuery is the best route to go about for this. I wanted to check to see if anyone knew of built in functionality for ListBoxFor that does this. The other option that I see is building a custom html extension. Even with this I still only see JS/jQuery being built and auto generated.
I'm pretty sure I can't do what I'm actually asking, but am wondering if there is some sort of workaround for the issue.
I have a page that has a drop down SELECT form element with several options. If one particular option (in this case, the first item) is selected, we show additional content (via jQuery). This works fine.
What happens, though, is that if I select item 2, the additional content disappears, as it should. I then go to a different page and then hit BACK. A that point, the page properly has kept that additional content hidden (as it was the last state) but the SELECT menu has been reset to the first item. I then have to click the SELECT, pick a different option, then select it again picking the first option, which finally brings the additional content back.
I can't trigger Javascript from what I can tell on a cached page (or is there a way?) Any other clever options?
One option I've come up with is to apply some sort of mouseover action to the area that houses the SELECT menu that does a quick 'reset elements' check. This seems a bit hacky and, of course, will produce an odd screen redraw unexpectedly for people.
You can record that the user action has taken place and re-execute it using JavaScript. You can store it in a cookie, then check for it on page load and reset the elements you want.
