Is it possible to send value from options on example like this where x need to be value from option. This select im using on partial and ajax works with manualy added value as x. THX!
<select data-request-data = "id: x " class="form-control custom-select" data-request="onChangeValue">
<option value="5">5</option>
<option value="10">10</option>
<option value="15">15</option>
<option value="20">20</option>
Just give your select a name, an unique name.
name="some_unique_name"
<select name="my_super_special_name_for_select" class="form-control custom-select" data-request="onChangeValue">
<option value="5">5</option>
<option value="10">10</option>
<option value="15">15</option>
<option value="20">20</option>
</select>
Then when you change the value the value of the field is sent along in post
The result of:
public function onChangeValue()
{
traceLog(post());
}
In the log you will see then a result corresponding to
["my_super_special_name_for_select" => 5 ]
So you can fetch it with post('my_super_special_name_for_select') or whatever name you have given the select element to get the value.
public function onChangeValue()
{
$id = post('my_super_special_name_for_select');
}
Yes you can send value from select. But for this you will need to put it inside a form and then call data request on it. Value will be sent as part of post(). It can't be sent dynamically like the way you are using. if you can elaborate your external conditions more I can suggest other solutions too.

I am working on a Spring MVC application that use Thymeleaf for the view.
I am absolutly new in Thymeleaf and I have the following problem.
At this stage of the work into a view I have a select which options values are hard coded into the code, something like this:
<select id="selReg" class="form-control">
<option value="" >--SELEZIONARE UN'AREA--</option>
<option value="areaUmanistica" >Area Umanistica</option>
<option value="areaLinguistica" >Area Linguistica</option>
<option value="areaScientifica" >Area Scientifica</option>
<option value="areaPsicoMotoria" >Area Psico-Motoria</option>
</select>
Now, into my controller, I retrieve a list of Tad1005Tipodisciplina objects using a service and I put this list into the model.
List<Tad1005Tipodisciplina> listaTipoDisciplina = tipoDisiplinaService.getListaTipoDisciplina();
model.addAttribute("listaTipoDisciplina", listaTipoDisciplina);
This Tad1005Tipodisciplina class contain this field:
private String desTipDis;
that I want to use in my view to dinamically show the content of the previous select.
How can I use this list putted into the model to dinamically populate my select options?
You need to iterate through your list using th:each in the select statement. This is where you define a variable that will represent each object in the list, which in turn you can use in each of the option tags like this:
<select id="selReg" class="form-control" th:each="object: ${listaTipoDisciplina}" th:field="*{listaTipoDisciplina}">
<option th:value="${listObject.desTipDis}" th:text="${object.desTipDis}"></option>
</select>
/Edit: A minute too late :)
Solved by myself, in this way:
<select id="selReg" class="form-control">
<option value="" >--SELEZIONARE UN'AREA--</option>
<option th:each="tipoDisciplina: ${listaTipoDisciplina}"
th:value="${tipoDisciplina.codTipDis}"
th:text="${tipoDisciplina.desTipDis}">
</option>
</select>

I have form with input select in the aplication/view codeigniter
and the form is submited by codeigniter, no ajax.
<select name="sel_options">
<option value="1">hi</option>
<option value="2" selected>bye</option>
</select>
in my aplication/controller
$this->input->post("sel_options");
result:
2
but i need the text ("bye");
When you post a value, it's going to use the value from the input. So in your case:
<select name="sel_options">
<option value="1">hi</option>
<option value="<!-- I'm Submitting this value -->" selected>bye</option>
</select>
The value for the second option is 2 (<option value="2" ... />) if you wanted to pull in the value from the html ('bye'), you'd have to set the value to be bye.
<option value="bye" selected>bye</option>
I have three dropdowns with same class name:
<select class="MyClass">
<option value="1">One</option>
<option value="2">Two</option>
<option value="3">Three</option>
</select>
<select class="MyClass">
<option value="1">One</option>
<option value="2">Two</option>
<option value="3">Three</option>
</select>
<select class="MyClass">
<option value="1">One</option>
<option value="2">Two</option>
<option value="3">Three</option>
</select>
I want to change any of these dropdown values based on any other dropdrop selected. If I select option two from second dropdown - I want 1st and 3rd dropdown values to be two. All these dropdown should change values no matter which one I select.
Thanks.
You will need JavaScript to do this. Here is an code example using jQuery:
$('.MyClass').on('change',function(){
$('.MyClass').val( $(this).val() );
});
This will add an EventListeneer for the change Element and update all DropDowns to the value of the changed one.
http://jsfiddle.net/CWP7Q/
you can use jQuery or normal JS, but my example contains Jquery, which will give you an idea. Please check the example in Jsfiddle.
The example binds a change event to the class name of the three selectors:
$(".MyClass").change(function(){
$(".MyClass").val($(this).val());
});
and Voila, every selector gets changed.
Somehting like (with jQuery)
$('.MyClass').change(function() {
$('.MyClass').val($(this).val());
});
I have a select list say of states in the country, which i have in a helper to include easily in any form. (removing most options to make it brief).
I have the value of the current selection stored in the database say "CA". How would i set selected="true" to option CA before rendering the list to the user?
#helper StateSelect(string name = "State")
{
<select name="#name" id="#name" class="required">
<option value="">-- Select -- </option>
<option value="AK">Alaska</option>
<option value="AL">Alabama</option>
<option value="AR">Arkansas</option>
<option value="AZ">Arizona</option>
<option value="CA">California</option>
<option value="CO">Colorado</option>
<option value="CT">Connecticut</option>
<option value="VA">Virginia</option>
<option value="VT">Vermont</option>
<option value="WA">Washington</option>
<option value="WV">West Virginia</option>
<option value="WI">Wisconsin</option>
<option value="WY">Wyoming</option>
</select>
}
As Darin Dimitrov says, the built-in stuff would be better. However, if you do need to, I think you have a few options:
Add code like this to every line:
<option value="CA" #(name == "CT" ? "selected=selected" : "")> Connecticut</option>
Just re-add the selected item to the top of the list
This keeps the code cleaner, the selected option is just repeated at the top (and selected there), before the entire list
how to disable option in drop down box using code igniter?i want to disable the value"------"in this drop down
echo "<tr class='background1'><td class='checkoutfield'>";
$countryall='';
$select='';
if(isset($order)) $country=$order['varShippingCountry']; else $country='';
if(isset($countries) && $countries !='') {
$countryall['']="Select";
foreach($countries as $key=>$value):
$countryall["226/United States"]="United States";
if($value['id'] !='226') {
//<option value=”spider” disabled=”disabled”>Spider</option>
$countryall['0']="-------------------------------------------------------";
$countryall["$value[id]/$value[varPrintableName]"]=$value['varPrintableName'];
}
if($value['id'] == $country)
$select="$value[id]/$value[varPrintableName]";
endforeach;
}
$selFunc='style="width:190px;" id="varShippingCountry" class="required" onchange="stateajax(this.value)" onKeyup="return changeText(\'varShippingCountry\',\'varPaymentCountry\',\'this.value\')"';
echo form_label('Country','varShippingCountry')."<span class='mandatory'>*</span></td><td>";
echo form_dropdown('varShippingCountry',$countryall,$selFunc);
You can't disable an item in a HTML select element - only disable the entire element.
Are you trying to make a separator between different sections of the list? In that case, you can use <optgroup>.
<select>
<optgroup label="Swedish Cars">
<option value="volvo">Volvo</option>
<option value="saab">Saab</option>
</optgroup>
<optgroup label="German Cars">
<option value="mercedes">Mercedes</option>
<option value="audi">Audi</option>
</optgroup>
</select>
You can make this happen in CodeIgniter by passing it a multidimensional array.
Alternatively, if you are just trying to make the first and default item look like ------, then add it in the normal way with an empty value. Then on validation, check that an empty value has not been passed.
