is it somehow possible to add an anchor (or hash) to a Struts 2 Action-URL? To be specific:
I have a html form which can be extended with more fields if the user clicks a button "add more fields". This Button sends a html submit to the backend (Action "thismyaction") where a list object is filled with another set of input fields. The action then returns to a tile "thisismyform" which loads the same jsp as before, where the new fieldset is visible.
(Unfortunately there is no way to achieve that via ajax / JS in this project at the time. I know that you usually add fields that way, but i got the project as it is.)
Each fieldset is counted (fieldset-0, if user adds more fields another set is added "fieldset-1"). The sets always contain the same fields, but enumerated.
What happens here? There is a post to the action which generates another fieldset and redirects back to the same page, where it renders all fieldsets. Important: the result type is "tiles"! I guess this is what makes it difficult.
Now I want to dynamically add an anchor to this URL "thisismyaction.do", like e.g. "thisismyaction.do#fieldset-1". Use Case: User adds another fieldset, post to the action => result type="tiles" => JSP, user sees reload of the page with the new, second fieldset and gets "scrolled" to the second fieldset via the anchor. Is that possible?
I hope I could describe it properly, what I want to achieve... If there are questions, feel free to ask.
Simplest way I can think of right away is
<script type="text/javascript">
window.location.hash = "fieldset-<s:text name="latestIdOfFieldSet" />";
</script>
If you can figure out what's gonna be latestIdOfFieldSet before you render your jsp and set it in your action method. you should get what you are trying to do.

I have made an app with jQuery mobile and laravel.
On the first page "mobilepage1" if have a form with a next button.
Also some of the form elements are dropdown menu's. The dropdown select options I get from a table in the database.
In the form on mobilepage1 I have a dropdown list with all department names:
I get this list from my controller like so:
$departmentlist = Company::find($usercompanyid)->departments;
This is how I display the list in the mobilepage1 form:
{{ Form::label('department', 'Department:')}}
<?php
foreach($afdelingslijst as $item) {
$afdelingsarray[$item->afdelingen] = $item->afdelingen;
}
?>
{{Form::select('size',$afdelingsarray)}}
On the second page I want to make a back button.
I tried the jQuery mobile way with a link with: data-rel="back"
But this does not work. I get a page error, it's missing the departmentlist used in mobilepage1. I can make a link to a route to mobilepage1, but I think all the information the user entered in mobilepage1 would be gone.
I see this url in the address bar when I am on mobilepage2 (this is after I filled in the form on mobilepage1 and clicked next).
/public/mobilepage2?size=Personeelszaken&size=32&directechef=Tineke&size=1&size=1&size=1&date-2=&size=1&time=&omschrijving=
Is there a way I can link to the the mobilepage1 route and still keep the information the user entered?
It looks like it would work just by hitting the back button if you passed in the department list with a view composer rather than through a route. Remove it from your route and place this in a file that's being autoloaded...
View::composer('mobilepage2', function($view)
{
$departmentlist = Company::find($usercompanyid)->departments()->lists('afdelingen','afdelingen');
$view->with('departmentlist', $departmentlist);
});
I'm not sure how you are finding $usercompanyid but you should be able to find it within the closure or pass it in by adding use ($usercompanyid) right after the function($view) part.
Also using the lists() function like that will build your array for you so you don't need to worry about the foreach loop in your view.
Since the values are getting passed back and forth as get variables, I think if you use Form::model() instead of Form::open(), it should place all those values back into the input fields for you.
I'm using ExpressionEngine and SafeCracker along with Ajax (plugin: jquery.form.js - http://jquery.malsup.com/form/).
Best I can tell, SafeCracker will only allow for updating a single entry at a time. However, the UI / UX necessitates that a list be displayed. I've proof of concept'ed an entry by entry on-demand form. That is, click a particular edit link next to each entry and a snippet of jquery creates a form along with displaying a submit button. Click submit and that single entry updates. The inputs don't exist until the Update link is clicked
What I would prefer to do, if possible, is to create the non-form and form versions of each entry as the page is renbered and use some sort of toggle to display one or the other. Again, doable. Then, when I click the Edit link I'd add the necessary attributes to the input so that entry's form elements will be read but the other (display: none) elements for the other entries will be ignored. I'm thinking (out loud) that if I add the attr("name", some-value) that would work. That is, an input with no name will be ignored.
Yes, I can test this and I will. However, even if it works I'm not sure if it's a best practice and/or there's a more ideal way of accomplishing my ends. I'm here looking for validation and/or additional expertise and input.
Thanks in advance.
Just set disabled property to inputs and they will excluded from Form submission, whatever input fields are hidden or visible. Different jQuery methods, like submit() and serialize() follow specification of HTML 4 and exclude all disabled controls of a forms. So one way is to set
$('your_input').prop('disabled', true);
or ,
$('your_input').attr('disabled', 'disabled');
Check following link:
http://www.w3.org/TR/html401/interact/forms.html#successful-controls
Also, you may use a general button instead of a submit, as result you can handle click event on it and within that event you can make exclusion, validation, manipulation on values and what ever you like.
You can put a disabled attribute on them server side or set the property via jQuery:
$(".hidden input").prop("disabled", true);
I am looking for the best way to create ajax enabled subforms from items in a list with MVC 3. A static list of values should be generated, but with an "edit" link/button next to every item, to toggle inline edits.
I did follow the tutorial at this link
http://blog.janjonas.net/2011-07-24/asp_net-mvc_3-ajax-form-jquery-validate-supporting-unobtrusive-client-side-validation-and-server-side-validation [1]
However it is based on the form edit fields always being visible
I'd like to show a static list with field values, but let the user activate an edit field by clicking "edit" (e.g. button)
I did modify the example at [1] by creating a default partial view with a form with submit button only. When posting the data by ajax the edit form will show. It looks like it is working, (I only need to hide validation errors on the first POST - which does not send real data).
Update:
An even better solution would probably be to leave out all forms in the static view, just have a single css class button/link next to each item, and let jquery fetch the relevant view for the clicked item. I am not sure how to do that with MVC 3+jQuery though.
Another update:
I discovered Ajax.Actionlink, which did exactly what I wanted!
I found out how to do it, and it turned out to be real simple!
I created two partial views.
One for rendering each static item. I used used Ajax.ActionLink with InsertionMode "replace", and set the parent of the item as the target
The second for rendering the form. Here I used Ajax.Beginform with similar options.
On successfully saved data, I returned the static view, on failure, I returned the partial view with the ajax form again.
I'm happy I found a MVC-centric way to do it (although it is fun creating custom stuff with jQuery)
It sounds like you need an inline editing plugin for jQuery. I would try jEditable. I have not used it myself but appears to have extensive docs.
this entry might help: code + video + explanation ;)

I have a "change password" page that needs to hash any passwords entered on the page via Javascript before sending. To complicate it, the page is loaded via a jQuery load() call, and is submitted by a jQuery.Form ajaxForm() call. Had everything working in MVC2, but MVC3 is giving me trouble.
That is, I have a page with a "Change Password" link that when clicked, loads the change password page into a jQuery modal popup, then the form on the change password page get's submitted via the jQuery.Form library (Essentially just wraps a $.ajax call), and returns it's result into the modal same modal popup.
Essentially, I have a model with two properties, OldPassword and NewPassword. I have two hidden fields generated by by view for these. They hold the hashed value of two other fields, PrehashOldPassword and PrehashNewPassword, and get updated via keyup events (I know, this means it does a whole SHA256 hash on every keyup... inefficient, but got the job doen for testing). The key here is that the regex validation and required field validation needs to be executed on these Prehash fields, which exist on the client side only (As obviously I don't want to transmit these fields to the server in any way).
So I manually create these two and add on the data-val-* attributes to the elements, i.e. they are NOT generated by the MVC helpers, etc. I am guessing that this is where I'm missing something. When the form submits with all fields empty, all of the errors popup that should, but the form goes right ahead and submits anyway.
==
So the things I've tried:
Yes, the unobtrusive library parse() method already get's called to parse the AJAX loaded form contents, and it appears to get all of the data validation stuff correctly, since I see the errors show up as fields blur(), and when I hit submit (before the ajax request completes and replaces the content of the popup).
Possible note: this call to the unobtrusive library's parse method happens AFTER the AJAX successfully loads the change password page into the popup... the AJAX form submit binding is put on document.ready of the loaded content, ergo, the AJAX form submission binding MAY be binding prior to, and thus firing before, the validation calls that the parse method may bind to the submit event...
However, (1) I am doing this same sort of thing in other places without issue, the ONLY DIFFERENCE being that I am manually putting these data-val-* attributes on elements I am creating manually! And (2), if I cause some kind of error on the OldPassword or NewPassword fields, i.e. a required field validation error by not loading a value into them, they display their error, and successfully STOP the form from submitting through the jQuery.Form method.
So I think something has to be wrong here:
<input id="PrehashNewPassword" type="password" name="PrehashNewPassword" data-val-required="The password field is required." data-val-regex-pattern="<%= RegexHelper.PasswordRegularExpression %>" data-val-regex="<%= RegexHelper.PasswordRegularExpressionError %>" data-val="true" />
I know that jquery.validate is getting the rules right, since I DO see the errors. It's just not stopping the form from submitting when their is an error in these manually generated elements, unless I do something like this, and add a pre-submit callback on the form's AJAX submission:
$("#ChangePasswordForm").ajaxForm({
beforeSubmit: function () { if (!$('#ChangePasswordForm').valid()) { return false; } },
target: '#overlay'
});
While this works, it is kind of ugly and I believe it causes the validation to be called twice... Not a huge deal, but less than ideal. So is there some other call that I need to make in the unobtrusive library to bind these?
Not sure if you found the problem, but you may try to
return false
in there if the form is not valid...
.
.
.
if (!$('form').valid()) {
return false;
}
// JSON POST...
.
.
.
If that doesn't work, then you could try to use:
$.validator.unobtrusive.parse($("#dynamicData"));
after dynamically adding your custom inputs. "dynamicData" is the ID of an element wrapped around the form
above found from here: http://weblogs.asp.net/imranbaloch/archive/2011/03/05/unobtrusive-client-side-validation-with-dynamic-contents-in-asp-net-mvc.aspx
Out of interest, what happens if you just get the form to validate?
<script type="text/javascript">
$("form").submit(function (evt) {
// validate here should trigger invalid fields
$('form').valid();
// JSON POST...
// stop form submitting
evt.preventDefault();
});
</script>
I have this ruby on rails code
<%= builder.select(:serving_size_id, '') %>
I have not specified any options on purpose because I set the options in a different way when the page loads (using jQuery and Ajax).
The question: Is there any way I can get the value from the column "serving_size_id" but not change that line? I have a partial which I use it for new and edit and I think it would be sweet if I can do the setting of the selected index in JS.
Any ideas?
I'm not sure I completely understand your question, but if you want to set the value of the select field with JavaScript, you need to obtain the value in JavaScript at some point. I can think of two ways of doing this:
1) When you get the options via AJAX, have the server indicate which one is selected. This can be done by returning HTML <option> tags with selected="selected" set for one of them. To do this, your AJAX request is going to have to provide information about the object this select field is for (so the server can look up the object's current serving_size_id value).
2) When you render the field in your original partial, also render some JavaScript which sets the current value of the field, for example, underneath what you have above:
<%= javascript_tag "var ssid = '#{builder.object.serving_size_id}';" %>
Then, after the options are retrived via AJAX, the ssid variable is checked and the correct option is selected.
using jQuery in rails is easy but a little more difficult than prototype.
ex: "div id="serving_size" class="nice" rel="<%=h num%>">Stuff Goes Here.../div>"
in application.js do the following:
//application.js
$(document).ready(function(){
if($('#serving_size'){
$('#serving_size').live("mouseover",function(){
//we are hovering over specific div id serving size
if($('#serving_size').hasAttr('rel')){
alert($('#serving_size').attr('rel'); //your dynamic rel value, and fire function
}
}
}
if('.nice'){
$('.nice').live("mouseover",function(){
//we are now hovering over any item on page with class nice
if($(this).hasAttr('rel')){
//we are now using jQuery object ref and finding if that obj has attr rel
alert($(this).attr('rel')); // shows dynamic rel value
}
}
}
});
If you use the above code you should be able to do anything you want and fire any custom code from each of your set event callbacks.
The 'live' function in jQuery is great because it can be called on items that will eventually be on the page (eg. if you fill in something with ajax, jQuery will be prepared for that item being in the page)
I hope this help.
