dropdown menu question, may be simple may not be - drop-down-menu

I have a webpage containing input tags like the one below eg.
<input value='Cut' name='container_cut_button' type='submit/>
<input value='Copy' name='container_copy_button' type='submit/>
I want to put these into a dropdown, I was hoping it would be something simple like
<select onchange='submit()'>
<option name='container_cut_button'>Cut</option>
<option name='container_copy_button'>Copy</option>
</select>
but no such luck,
Anyone have any ideas about how this could be done?
Thanks in advance

Use the "value" attribute of the options rather than their name.
<select name="action">
<option value="cut_item">Cut</option>
<option value="save_item">Save</option>
</select>
On the server, you'll check the value of the variable "action." It will be either "cut_item" or "save_item".

I called a javascript function in the select tag ie. onchange="exec(value)", the function gets the select id and inserts the proper name attribute based on it value.
function exec(val){
if(val=='cut'){
document.getElementById("action").setAttribute("name", "cut")
}
}
This worked out ok

How can I use a list of object in the model to automatically populate the options of a select in Thymeleaf view?

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>

magento set drop down as readonly not working

I need to set a drop down as readonly. I put it as;
<select readonly="readonly" name="name" >
<option>1</option>
<option>2</option>
<select>
But this is not working. Since it is readonly, we can change the drop down value.
Please help.Thank You.
The select tag doesn't have a readonly attribute. It does have a disabled.
The problem with disabled is that form inputs don't get included in the POST / GET data.
To get around this, add another hidden input with the same name and value.
You can use something like this:
<select>
<option disabled="disabled">1</option>
<option selected="selected">2</option>
</select>

Remove some items in dropdownlist based on selected keywords

I have a dropdownlist in my page and the html part lists below:
<select id="Permission_id" name="Permission_id"><option value="">Pls select</option>
<option value="001f492b-fbb2-440c-b2ac-1fab5d97f5e3">super</option>
<option value="559ede95-1dbb-45d5-ae41-2df6f460e87a">admin</option>
<option value="80b330ee-37dc-42c4-8902-c30254112c11">user</option>
<select>
And in the same page, I have another dropdownlist , the html part lists below:
<select id="TopPranet_id" name="TopPranet_id"><option value="">Pls select</option>
<option value="65c61442-e02f-4071-b746-2c7cbfcc859a">Settings--admin</option>
<option value="66d21c35-66a2-40d8-a9db-675b337fa0bb">Control--admin</option>
<option value="cd612bfc-9f61-4228-b986-90bda4be9d8d">Action--admin</option>
<option value="2a137846-5ae0-4104-b0c9-be09a0e772d8">Settings--super</option>
<option value="b75c43f3-cafb-41a2-a76b-c572fffd8a6a">Control--super</option>
<option value="2c3f618c-373f-4559-967f-d8dcea1b6996">Action--super</option>
</select>
Now I want to do things like below:
When Permission_id's select item changes, then TopPranet_id's item will only contains the items that have Permission_id's selected text inside. that is, if I select admin in Permission_id control, then TopPranet_id control will only contains Settings--admin,Control--admin,Action--admin item, others are removed.
I know I can use Jquery to do this, but I am a newer to this, also, regex maybe also required for doing this.
Need your help, thx.
Please check here i have added one ex
Here
You html all seems ok
Now
in javascript
$('#Permission_id').change(function()
{
$('#TopPranet_id option').each(function()
{
if(this.innerHTML.indexOf($('#Permission_id :selected').text())!=-1)
{}
else
{
this.style.display='none';
}
});
});
We have added change function which will detect the change event of the first dropdown and after this we will check that text with second dropdown which will show and hide the dropdowns

how to make a select box which has a particular value preselected using grails2.0

I have the following line in my gsp
<g:select name="platform" from="['Date','Time','Place','Calendar']"/>
I want the Time option to be automatically selected while loading the page.
<select>
<option value="Date">Date</option>
<option value="Time" selected="selected">Time</option>
<option value="Place">Place</option>
<option value="Calendar">Calendar</option>
</select>
This is what i need when my gsp page got rendered into html.
Please help me
Thanks in advance
You can do it by setting the g:select value
<g:select name="platform" from="['Date','Time','Place','Calendar']" value="'Time'"/>
but it would be better to bind it to an model.

Watir question regarding selecting a hidden dropdown

I have two dropdowns, the second dropdown does not show until a choice is made from the first one. Using watir, i can select the first dropdown, and when i watch it, the second one becomes active, but it cannot select it. i just tried the regular select_list using name and id. Here is the code for the second drop down.
<td>
<input type="hidden" value="1" name="list" id="list">
<script type="text/JavaScript" language="JavaScript"></script>
<select>
<option value="">1</option>
<option value="2">2</option>
<option value="3">3</option>
</select>
</td>
I've also notice the value for the hidden field change as i select different options.
Thanks for any help
The way that I usually access drop down lists is by using this string:
#browser.select_list(:name, "list").set("3")
Does this help?
I usually select hidden dropdowns this way
ie.hidden(:name=>"list").value='2'
Try this:
browserObj = Watir::Browser.new
browserObj.goto('you html in browser')
//browserObj.hidden(:id,"list").value
browserObj.select_list(:name, "list").select_value('2')
