I've created a wizard from a long form with a help of jquery.quickWizard plugin. One of the good things about this plugin that it works with jquery.validate which is really handy.
Now i need to display current step(in the wizard) above the form, are there ready to use solutions for that?

I am working on an old legacy application which used document.forms[index] approach to access elements in the form and to submit the form. My task is to add a new top panel with few textboxes and buttons. I am using a form for this. This top panel is to be included in all the pages in the application. Now, all the pages stop working since form[index] needs to be updated in all the pages. I know using the form name is the best approach. I have around 1000 places to change. What is the best approach to avoid this problem? I still want to use form for my top panel since I am using spring forms to get the data. Any valuable advice will be appreciated. Thanks.
If you looked up the definition of "unmaintainable", that would be a good example.
One trick might be to leave one set of forms, hidden, with the legacy stuff in them, then make another set, lower in the HTML, that the user sees. Then use some JavaScript to map the data back into the original forms in order to continue to work with the expectations of the legacy code. This keeps everything in the same index-order.
I was wondering if there is already a framework or a jquery plugin which i can use to add constraints to form fields. With "constraints" in this case I don't want to say that field x is an e-mail field and needs to be validated as such but i want to define relations between form fields like:
If there is something selected in checkbox A --> enable Button B
If there are at least X entries selected in list A --> enable form field B
and so on and so forth..
I'm currently on the point of implementing it myself but I wanted to make sure that I don't reinvent the wheel.
It could be any JavaScript framework (standalone or jquery plugin).
Why a plugin? This is fairly easy with just jQuery:
$('input.A:checkbox').change(function() {
$('button.B').prop('disabled', !($(this).prop('checked'));
});
$('select.C').change(function() {
$('button.D').prop('disabled', !($(this).find('option:selected').length >= 10));
});
We're just assigning handlers to the events that happen when the inputs are changed - and I enable or disable the field depending on my condition.
I think it's better than getting a plugin because:
You're saving on HTTP requests for more files
You're saving performance by not loading more JS code
This is fairly simple as-is and there's no point to overcomplicate it.
See demo
If you use something like knockout you'd be able to make use of the knockoutvalidation framework.. or, in the past I've used jqbootstrapvalidation... the latter obviously requires bootstrap as well.
There are quite a few code samples on both sites & both frameworks are pretty easy to use. Feel free to comment on this post if you need any more specific help/advice.
Just a word of warning. If you do use knockout. Go with knockoutvalidation, and not bootstrap validation... or you'll have sleepless nights trying to get the 2 to play nicely.
Here is a jQuery plugin you could use:

I'm trying to build a webform that has multiple stages. I'm patterning it off of the Stack Overflow / Stack Exchange flagging webform. The problem is, I'm not sure how to trigger the "next stage" action.
To illustrate, if one wants to flag a question on Stack Overflow, you click flag and then a popup prompts you to make a choice. If you choose the second option ("it doesn't belong here, or it is a duplicate") the form automagically takes you to a second screen.
First screen:
Upon click, it auto-redirects to:
The problem is that I don't know what the underlying trigger is. How does clicking that radio button send the end user to the next screen?
I tried checking the source, but I have a feeling I'm only seeing half the picture:
No amount of HTML tutorials I find have any practice example similar to this. I suspect this is JavaScript, but I can't find the linked .js file that would trigger these actions.
So: How does the webform auto-redirect upon click? As a follow-up, if it's using JavaScript, is there an HTML/CSS-only workaround I can use?
It might help to think about this at a lower level than frameworks. There are two ways one could make a multi-stage form.
The first (and generally older) way is to store the state on the server. Each stage of the form is actually a separate form, and the client's progress through the questionnaire is kept on the server (for example, as part of the session data).
The second way (the more modern one) is to use JavaScript, as you suspected. There is actually very little black magic in this case, and no auto-redirects on clicks at all. All you do is have one very long form where you show/hide some of the elements depending on the user's selections (of course, you could have multiple <form> elements which you show/hide).
Well, I'd use some sort of jQuery wizard plugin and adapt it to my needs. I did it very recently and it wasn't that hard. You should try SmartWizard 3.0, it's pretty active, the last release was about 2 months ago and the coders answered my questions pretty fast.
Here it is: https://github.com/mstratman/jQuery-Smart-Wizard
You can trigger the wizard to advance to the next step linking an event to the action of clicking the radio button.
Good luck :)
I currently had my form set up so that each section was refreshed using Ajax, however it didn’t degrade gracefully with JavaScript turned off and I’ve looked into putting each part of the form in to a separate view which works fine but isn’t that great to be honest.
I know the client wants it to look nice so I thought about using jQuery to show and hide forms, so if JavaScript is turned off then all of the forms build in to one long form. However the only problem I am facing is that after each section the user needs to submit this information for it to be validated before the next stage is completed. How can I do this if JavaScript is turned off because the other forms will be visible...
Any ideas? Thanks.
You might consider using one long form divided into sections, and then if JavaScript is enabled you hide all but one section at a time, providing navigation between the sections (via tabs, for instance).
Alternately, you could look at using script and noscript sections, but then you end up duplicating the form (once in the script sections, once in the noscript sections) and it starts getting to be a maintenance problem.
What you do wrong is that you're thinking reverse. When you have it working with javascript disabled then it's much easier to apply some javascript functionality.
In addition to that I would display different forms based on wich step in the process the user are. And to that form pass the values from the last step into hidden fields. That way you can have a "step"-registration without js enabled.
?step=1 and let say you use php <?php if (isset($_GET['step']) && $_GET['step'] == '1'): ?>
Then just reload the part that contains the form with ajax.
Morning folks.
Novice Rich here once again requesting assistance.
I have just started dabbling with javascript and although I have set up a few onclick/change for setting the focus of radio buttons,that's pretty much my limit.
In my c# code behind, I would like to have an 'onchange' function whereby once a client starts to type in my autocomplete textbox, a drop down list (which is likely to have been populated previously) is reset/cleared to it's original state.
Anyone got any ideas how to do this?
(Chances are I haven't exp[lained myself very well here)
What you want here is to start exploring jQuery. When you find yourself familiar with it, create a server-side ASP.NET Handler that returns JSON data to your jQuery.getJSON call and from that, populate your autocomplete textbox.
Or, you can of course not reinvent the wheel and just use one of the plethora of jQuery Auto-Complete plug-ins available out there. Whether you'd still need the server-side handler to provide the auto-complete plugin with data depends on your use-case, but in most cases you'd get much better performance out of pre-populating the data when the page loads.
