I am asking for help. Is there any way I could fill an input box based on drop down selection? On my modal I have a dropdown option for subject description and I would like the subject number input field dynamically change its value. Any help would be much appreciated.
This is how I retrieved the data for my dropdown
subjects=DB::table('programs_subj')->select('corsdes', 'corsno')->get()
This is my dropdown code for the subject description which is working and the selected is saved but I could quite how to incorporate the subject number
<select name="corsdes" id="corsdes" wire:model="corsdes">
<option value="corsdes" wire:model="corsdes"></option>
#foreach($subjects as $sbj)
<option value="{{ $sbj->corsdes }}">{{ $sbj->corsdes}}</option>
#endforeach
</select>
<input name="corsno" id="corsno" wire:model="corsno"><input>
if you have the public properties $corsdes and $corsno then:
public function updatedCorsdes($value)
{
$this->corsno = $this->subjects->where('corsdes',$value)->first()->corsno;
}

So I have this project, and I want to return an object, from the previous choice of 2 select items. How can I do it? for example:
<select class="form-control" id="cityPicker1">
<option value="0">select option</option>
<option th:each="city: ${listCities}" th:value="${city.number}" th:text="${city.name}"></option>
</select>
<select class="form-control" id="cityPicker2">
<option value="0">select option</option>
<option th:each="city: ${listCities}" th:value="${city.number}" th:text="${city.name}"></option>
</select>
I want to display an item from another item list which has a number1 field and a number2 something like ticket.number1 and ticket.number2 but they have to match the values from the previous selects. I can't seem to find anything. Any ideas?
This is how I set it up in the controller:
#GetMapping("/tickets")
public String viewTicketsPage(Model model) {
List<City> listCities = cityRepo.findAll();
List<Ticket> listTickets = ticketRepo.findAll();
model.addAttribute("listCities", listCities);
model.addAttribute("listTickets", listTickets);
return "tickets";
}
I need to clarify a few things about your question.
1 - did you manage to get the checkboxes to work?
2 - can you send the selected data to the controller?
you need a controller to receive data from the page, send this data to the repository to fetch other data..
I believe you want to select a table, where the data matches the selected ones. .
take a look at JPQL, maybe this will help you:

I want to save the name of a department in the table employees, in the select component it displays the name but saves the id, so I think the problem is in it.
This is the select component:
{{Form::select('nombre_dep', $departamentos, null, array('class'=>'form-control', 'placeholder'=>'Asignar departamento'))}}
In my controller I have this for returning to the view:
$departamentos = departamento::pluck('nombre_dep', 'id');
In the model for employee I have this for relation:
public function departamentos(){
return $this->belongsTo('App\departamentos');
}
I expect to save in that field for example: production instead of 1 that could be id of the department
The selected answer is correct, but offers no explanation.
The issue is that you create your LaravelCollective Form::select so the integer id is sent in the ensuing request. You can verify this by viewing the source of the Form element in your rendered blade html. It currently will look like:
<select class="form-control" name="nombre_dep">
<option selected="selected" value="">Asignar departamento</option>
<option value="1">Production</option>
<option value="2">Department 2</option>
<option value="3">Department 3</option>
</select>
so when the action is triggered with (say) option 1 selected, your generated request simply has "nombre_dep" => "1".
You need to structure your form with the desired option value. like
<select class="form-control" name="nombre_dep">
<option selected="selected" value="">Asignar departamento</option>
<option value="Production">Production</option>
<option value="Department 2">Department 2</option>
<option value="Department 3">Department 3</option>
</select>
To do this, pass the $departamentos variable from your Controller like so:
$departamentos = array('Production' => 'Production', 'Department 2' => 'Department 2', 'Department 3' => 'Department 3');
and an easy way to do that (as the answer https://stackoverflow.com/a/56673741/8093282 stated):
$departamentos = departamento::pluck('nombre_dep', 'nombre_dep');
Perform the pluck specifying in the key parameter (the second parameter), the field from which you want to get the value to use in the value attribute of the select.
$departamentos = departamento::pluck('nombre_dep', 'nombre_dep');
Then when you pass the $departamentos array to the Laravel Collective select(), it will create an <option> element for each array element, using the array key as value attribute and the array value as option tag content.
{{ Form::select('nombre_dep', $departamentos) }}
I have a requirement to load a set of pre-defined values from the database but also give a user ability to enter a custom values as well. Good example is here:
https://jsfiddle.net/api/mdn/
<label>Choose a browser from this list:
<input list="browsers" name="myBrowser" /></label>
<datalist id="browsers">
<option value="Chrome">
<option value="Firefox">
<option value="Internet Explorer">
<option value="Opera">
<option value="Safari">
<option value="Microsoft Edge">
</datalist>
Is it possible to implement this feature in JQGrid?
This will only happen in the edit mode one per row. It should function exactly as as selecting from a drop down, only one value will be displayed and updated/saved. I will have to use is for only one column where each row will have a list of dynamic predefined values coming from the database.
Here is my start:
<datalist id="browsers">
<option value="Chrome">
<option value="Firefox">
<option value="Internet Explorer">
<option value="Opera">
<option value="Safari">
<option value="Microsoft Edge">
</datalist>
function myelem (value, options) {
var el = document.createElement("input");
el.type='text';
options.id = 'myBrowser';
el.setAttribute("list", "browsers");
return el;
}
The question is how to populate the datalist dynamically for each row based on the next column value and after exiting the edit mode save the selected value to the db?
Thank you,
If a value was previously saved for this column it should be displayed. When a user enters an edit mode the previously displayed value will be at the top (default) but the same set of predefined values should be available in the drop down with the option to enter a new custom value.
Thanks.
I found this very interesting and have created new article in our Guriddo Knowledge base where I explain in detail how to do this
<select id="selectedSchool" size="3" multiple="multiple" name="selectedSchool">
#foreach (var item in ViewBag.pt)
{
<OPTION VALUE="#item.entityID">#item.name</OPTION>
}
</select>
on my page the user selects a school from the list of schools, each school has a unique ID which is needed and passed via the VALUE attribute, I also would like to pick up the name
(item.name) that was selected how can I resolve this info from my control Action Result?
public ActionResult ResultsSchoolsAttended(List<int> selectedSchool)
i iterate through the list of results, but I would aslo like selectedSchool.name to enter back in the db as 'display text'
how can i do this?
Well, MVC can only give you what is in the HTTP POST. And if you look at that, you will see that the <option> inner HTML isn't there. So you have only two choices:
Include it in the value in your markup, or
Look it up in your ResultsSchoolsAttended action based on the submitted value.
I'd pick the second, personally.
Is there anyway of showing a tooltip on the dropdown list?
such as when the list is dropped and a person hovers over each option a tooltip or something with details appears. this is for a drop down list with a cascading drop down.
this is for asp.net
Marco, not sure what browser your demographic is, but the standard code below works for FF.
<select>
<option value="1" title="this is text about the value">Option 1</option>
</select>
You can do something like this in code behind (c#):
foreach (Widget w in Widgets)
{
ListItem item = new ListItem(w.Name, w.WidgetID.ToString());
item.Attributes.Add("title", w.TooltipText);
ddlWidgets.Items.Add(item);
}
