Meteor Handlebars templates: switching from text to input - forms

One part of my meteor application is a semi-collaborative table where users can edit different rows at the same time. When a user is editing a row, the static text values need to switch to input boxes so that the values can be edited and then saved. I would like a template/helper to do this, essentially I want:
<td>
{{#if iAmEditing}}
{{foo}}
{{else}}
<input type="text" name="foo" value="{{foo}}">
</td>
except that there are several columns with different values of "foo" and I don't want to copy and paste this several times. What's the right way to approach this with templates and helpers?
Another approach might be to use the HTML5 contenteditable attribute. Either way, what is the right way to template these values with handlebars?

You should be able to integrate with Bootstrap Editable

For reference, an answer to the original question...
As of today, handlebars partials can't accept anything other than a context argument, but helpers can. Hence. you can define a helper that sets up the context for the template:
Coffeescript:
Handlebars.registerHelper "eventCell", (context, field, editable) ->
return new Handlebars.SafeString(
Template._eventCell
_id: context._id
field: field
value: context[field]
editable: editable
)
Template:
<template name="_eventCell">
<td><div data-ref="{{field}}" class="{{#if editable}}editable{{/if}}">
{{value}}
</div></td>
</template>
Then, I just use the following to render each field:
{{eventCell this "province" iAmEditing}}
I ended up integrating with bootstrap editable, so the template is a little different than my original question. Also, I'm not sure if this is the best way to do it, but it's a lot cleaner than what I had before.

meteor-editable is a new project implementing something like x-editable, but nicely integrated with Meteor reactivity. Unfortunately inline editing is not supported yet (you have to use a popover the way it's set up now).

Set class or ID on <h:inputHidden> in JSF

I'm trying to set a class or id parameter on a <h:inputHidden> in JSF. The code looks like this:
<h:inputHidden value="#{getData.name}" class="targ" />
But in the browser, the class isn't set:
<input type="hidden" name="j_idt6" value="j_idt6">
I need to set a class to this parameter, because I have a JavaScript autocomplete function for a <h:inputText> that sets a value in the hidden input, which needs to be passed in the next page.
Any ideas? Thanks!
I know it's a little bit late, but it can help someone in the future.
As inputHidden shows nothing in the browser there's no sense to allow it to have a class.
You can use the Id but as the Id could change as you change the component parents using it would bring some headache.
I'd suggest as a workaround, you can give it a parent so you can manipulate it by javascript.
Exemple:
JSF
<h:panelGroup styleClass="someCssClass">
<h:inputHidden id="someId" value="someValue" />
</h:panelGroup>
Javascript (using jQuery, you could use pure javascript also)
$('.someCssClass input[type=hidden]').val('yourNewValue');
None of these answers here satisfied my needs (need the PrimeFaces component, need class not ID, wrapping is too much work), so here's what I came up with:
Use pass-through attributes: https://www.primefaces.org/jsf-2-2-pass-through-attributes
Use pass:hidden-class="blah" (in my case, it's xmlns:pass up top)
Use [attribute=value] selector:
https://www.w3schools.com/cssref/sel_attribute_value.asp
document.querySelector multiple data-attributes in one element
That basically boils down to using something like this (because h:inputHidden becomes a regular input): document.querySelector("input[hidden-class=" + blah + "]")
Please, see similar question - How can I know the id of a JSF component so I can use in Javascript
You can sed "id" property, but in final html code it can be not the same, but composite: for example, if your input with id="myhidden" is inside form with id="myform", final input will have id="myform:myhidden".
In the end, I used a standard HTML <input type="hidden"> tag, as I had no advantages for using the JSF one. If you're trying to set a value in a hidden input with JavaScript, I recommend using this workaround.

KnockoutJS and Property-Dependent Create/Edit-View (Master/Detail Scenario)

I am having trouble creating a property-dependent create/edit-view in KnockoutJS.
Here's the thing: everything I create are "People" of sorts - it could be a Healthcare Professional, Plumber, Mechanic or Engineer. Depending on what kind/type of person it is, I need to enter different data.
Here an example:
Healthcare Professional: Name, Telephone, Hospital, etc.
Plumber: Name, Telephone, Crafts, etc.
Engineer: Name, Telephone, Specialities, etc.
What I can do is create properties on my ViewModels such as "showCity", "showHospital" and so on to hide individual form-fields.
However, for the sake of separation, I would like to use entirely different forms: again, I could set the respective form to only show if the condition is met.
However, I would like KnockoutJS to only render the respective form that should be used (the Person's type is always determined when it is first created - it cannot be changed).
What I don't end-up doing is have one form that is shown and ten that are there (and data-bound) but hidden.
I tried using the "if" binding like so: <div data-bind="with: $root.selectedPerson"><form data-bind="if: $data.type='mathematician'"></form></div>, but to no avail.
Would anybody know what the best-practice is in this case?
Your if binding is setting the $data.type value, not comparing it. Try:
<div data-bind="with: $root.selectedPerson"><form data-bind="if: $data.type() === 'mathematician'"></form></div>
Although this is fine, I always try to avoid code in my data-binding markup. I would try and create a computed that would return the resulting true/false of the comparison, but in your situation, you would need one for each person type, and that would get tricky. For that, I would turn to templates. You could do:
<div data-bind="template: { name: $root.selectedPerson().type, data: $root.selectedPerson }"></div>
<script type="text/html" id="mathematician">...</script>
<script type="text/html" id="plumber">...</script>
*Note: As of KO version 2.3.0, the name property of the template binding can accept observables. If you're using a previous version, be sure to call the observable in the binding: name: $root.selectedPerson().type()

Joomla Component Formatting Form Inputs

I want to be able to format a field in Joomla. I'm creating a form that has a number of inputs and I want to format the inputs to have a yellow background and be of various lengths. Currently my form is produced in the standard Joomla way:
<div class="tablecol1">
<?php echo $this->form->getLabel('dob'); ?>:
</div>
<div class="tablecol2">
<?php echo $this->form->getInput('dob'); ?>
</div>
I've looked through the JForm stuff but I can't figure out how to control the format of the generated input box?
help would be great thanks
Setting a class for the inputs would be the quickest and easiest way as mentioned by MasterAM. You can then style it however you wish using CSS.
If you need to change the HTML or particular attributes that are not possible to set through the default parameters, then the next option is to create your own field type.
You can either override the existing ones or create ones with new names. For example you could copy the checkbox field (/library/joomla/form/fields/checkbox.php) into your own folder (/components/com_mycomponent/form/fields).
If you leave it as JFormFieldCheckbox it will override the default one. If you rename it - e.g. JFormFieldCustomCheckbox then you can have your own one.
The primary function you will want to look at is getInput(). This generates the HTML and will let you create your own input html with whatever attributes you wish.
To use custom attributes/settings from your form xml file, in your getInput() function you will use something like:
$fieldsize = $this->element['field_size'];

enclosing custom form element with form tag (drupal 6.x)

I've created custom form using FAPI for my site. And I place each control at specific location base on template provided by the designer. For instance -
<div id="myform">
<span>Enter Your Name : </span> <?php print drupal_render($form['name']); ?>
<span>Gender : </span><?php print drupal_render($form['gender_radio']); ?>
....
</div>
<?php print drupal_render($form['submit']); ?>
Here's my question - How do I enclose all the elements inside form tag? Is hardcoding the form tag inside the template file right way to do in drupal? or is it better to create in hook_form? But doing so would require me to add closing form tag at the end manually. Any suggestion would be highly appreciated.
Drupal - 6.x
It sounds like maybe you read about building individual fields, but skipped over some basic concepts of FAPI. In short, if you call the form with drupal_get_form(), you get the form container (and many of the benefits of using FAPI, e.g. tokens, validation, etc.) automatically. To handle the markup that goes around your form elements, you can then use #prefix, #suffix, and markup elements.
You can assemble the whole form from the outside in like you're doing, but there are few cases in which that would really be worthwhile. If you really want to do that, you basically want to copy what drupal_get_form() does to get the form wrapper added in a way that will work with FAPI.

Div as Ajax.ActionLink

Is it possible to create Ajax.ActionLink which has instead of text, the whole DIV?
I'd like to map div on Ajax.ActionLink
I don't think that this will work using the standard MVC Ajax scripts. I believe that the MVC javascript is created to use an <a> element by default. On a different note, embedding a div tag within an <a> is not valid XHTML. What are you trying to achieve?
Using Jquery is probably the easiet way you want to go. As an example:
<div onclick="SomeAjaxFunction()">some div content</div>
function SomeAjaxFunction()
{
$.get('<%= Url.Action("SomeAction", "InSomeController") %>', function(data) {
$('.result').html(data); // assuming a partial view
alert('Load was performed.');
});
}
However, if you are dead set on using MS Ajax, to work with divs, you need to possibly look at the Sys.Mvc.MvcHelpers._asyncRequest function and do some of your own re-wrapping to make it usable. I have not tried or tested this, so use at your own risk. (Stick with the Jquery, there is far better help and support available.)
