I'm populating a select list using razor and its giving me some strange results. The items in the list contain spaces, the text created is ok, but the value has been split into sections for each word in the text description. Here's my razor code
<select name="fromReport[]" id="multiselectReport" class="form-control" size="15" multiple="multiple">
#foreach (var item in Model.AvailableReports)
{
<option value=#item>#item</option>
}
</select>
and the resulting HTML
<select id="multiselect_toRpt" class="form-control" name="toReport[]" size="15" multiple="multiple">
<option value="All" trades="" activity="" last="" week="">All Trades Activity Last Week</option>
<option value="All" trades="" for="" delivery="" last="" month="">All Trades For Delivery Last Month</option>
<option value="Energy" costs="" report="">Energy Costs Report</option>
</select>
so its created a section in the definition for each word in the text, why is this ?
Wrap the value attribute value in quotes. Single quotes or double quotes will work.
<option value="#item">#item</option>
figured it out
#foreach (var item in Model.AvailableReports)
{
<option value="#item">#item</option>
}

I have code with drop down menu. The object for this menu has few fields. Two of them are playerPosition and isFirstSquadPlayer.
If isFirstSquadPlayer is TRUE I need to display in menu player.playerPosition.
Trying on few ways but failed.
My controller:
public String players(#PathVariable long clubId, Model model) {
Club club = this.clubRepository.findByClubId(clubId);
model.addAttribute("players", this.playerRepository.findAllByPlayerClub(club));
return "players";
}
My HTML:
<select name="playerposition"
id="createnewplayerposition" th:value="${player.playerPosition}" required>
<option value="0">Select position for player</option>
<!--HERE NEED PROPER REQUEST -->
<option th:selected="${player.playerPosition}" th:text="${player.playerPosition}"></option>
<option value="GK">Goalkeeper</option>
<option value="RWB">Right Wingback</option>
<option value="RCB">Right Centreback</option>
(...)
</select>
as per kindly advice:
ok, tried and found such request with thymeleaf conditional:
<option th:if="${player.playerPosition!=null}" th:selected="${player.playerPosition}" th:text="${player.playerPosition}"></option>
it's not excactly how I expected but gives some solution –
I got the following drop-down list - SELECT element - construction in my ZPT template:
<select id="record_selector">
<option tal:repeat="record view/records" tal:attributes="value record/id">
<span tal:replace="record/name"></span>
</option>
</select>
How make it possible to have selected OPTION which value is equal to one from the corresponding view property (i.e. for example, OPTION tag value == view/currentRecordId then make it selected).
Using the sdupton's clue, I got the following solution:
<select id="record_selector">
<tal:block tal:repeat="record view/records">
<option tal:condition="python: record['id'] != view.recordId"
tal:attributes="value record/id"
tal:content="record/name">
</option>
<option tal:condition="python: record['id'] == view.recordId"
tal:attributes="value record/id"
tal:content="record/name"
selected>
</option>
</tal:block>
</select>
TAL conditionals are awesome :)
I found another solution here: https://old.zope.org/Members/peterbe/DTML2ZPT/index.html#example14
This still works with Zope 5.3 on Python 3.
<select id="record_selector">
<option
tal:repeat="record view/records"
tal:attributes="
value record/id;
selected python: record['id'] == view.currentRecordId">
<span tal:replace="record/name"></span>
</option>
</select>
I am trying to send a listbox back to my controller from my view. I dynamically add items to it with a text box and button, and I want to be able to send all of these items back to my view in some kind of array. How would I go about doing this?
I had the following modelcode:
[HttpPost]
public ActionResult BasicIdentificationIndex(MyObject returndata, List<int> ints)
And then some input boxes:
<input type="text" name="ints" value="1" />
<input type="text" name="ints" value="4" />
<input type="text" name="ints" value="2" />
<input type="text" name="ints" value="8" />
This code works and is returned to my controller(not null).
EDIT:
My issue is that I cannot get a select list to post back to my controller. I would like to send the following back to my controller:
<select name="selectfrom" id="select-from" multiple size="5">
<option value="String1">Item 1</option>
<option value="String2">Item 2</option>
<option value="String3">Item 3</option>
<option value="String4">Item 4</option>
</select>
How would I go about doing this so that I can send a list of all the options( String1,String2,etc.) back to my controller? I have tried the following:
Controller:
public ActionResult BasicIdentificationIndex(BasicIdentificationModel returndata,ICollection<String> AerialItems)
Model:
public String AerialItems { get; set; }
View:
<select name="AerialItems" id="select-to" multiple size="5">
<option value="5">Item 5</option>
<option value="6">Item 6</option>
<option value="7">Item 7</option>
</select>
But The item returned back to the controller is always null.
You should be able to just model bind back to a collection of ints...
I'm somewhat confused because this seemed to be copied from Haack's blog post on the subject... What you have listed should work, but if it's not could you include the rest of your code?
http://haacked.com/archive/2008/10/23/model-binding-to-a-list.aspx
Figured it out. I need to use Javascript to select all the items in the list. This will post them all back in the collection.
I would like to make a select box using <g:select/> that translates to this html:
<select id="myselect" name="myselect">
<option value="r">RED</option>
<option value="g">GREEN</option>
<option value="b">BLUE</option>
</select>
I would also like the value to be preselected from a bean when the page reloads.
I'm doing this inside a so I have a table with each row having a separate option box.
I'm currently accomplishing this in the below html:
<g:each in=${mylist} status="i" var="myInst">
<select id="status${myInst}" name="status${myInst}" data-id="${myInst.id}">
<option value="r" <g:if test="${myInst.color == "r"}">selected</g:if>>RED</option>
<option value="g" <g:if test="${myInst.color == "g"}">selected</g:if>>Green</option>
<option value="b" <g:if test="${myInst.color == "b"}">selected</g:if>>BLUE</option>
</select>
</g:each>
This all works fine but I'd like to change that ugly <select> into <g:select>
<g:select id="myselect" name="myselect" value="${myInst.color}"
from="${['r': 'RED', 'g': 'GREEN', 'b': 'BLUE']}"
optionKey="key" optionValue="value" />
you have to declare the "myselect" inside your domain class. I have been having trouble with this too, but I'm about 2 weeks ahead of you. see how do I write a set for g:select tag
I have a form which allows the user to create extra "rows" using JQuery (using .clone) so that they can decide how many of the same information they need to submit. My issue is that I cannot work out how to access these form items within my controller.
the form that is being submitted may look like this
<input type="text" name="Amount" id="Amount">
<select name="Item">
<option value="1">Item 1"</option>
<option value="2">Item 2"</option>
<option value="3">Item 3"</option>
</select>
<input type="text" name="Amount" id="Amount">
<select name="Item">
<option value="1">Item 1"</option>
<option value="2">Item 2"</option>
<option value="3">Item 3"</option>
</select>
<input type="text" name="Amount" id="Amount">
<select name="Item">
<option value="1">Item 1"</option>
<option value="2">Item 2"</option>
<option value="3">Item 3"</option>
</select>
Basically, the block between input and the select could be repeated an infinite number of times. When I submit to the controller I am then using FormCollection form to access the form elements. from there I am unsure how I can access the items that have been submitted. I thought of using a for loop and then accessing them via something like form["Amount"][i] but obviously that is not going to work.
Am I going about this the right way and if so, does anyone have any suggestions about how this might work?
Thanks in advance.
Old question, but still...
You can get the posted values as an array by calling Request.Form.GetValues, or Request.QueryString.GetValues. For example:
string[] amounts = Request.Form.GetValues("Amount");
And the amounts array will contain the correct values, so you can post values containing comas, dots, whatever, and don't worry about splitting/parsing it.
Of course if you are running MVC, use the modelbinder to do it. But you can use this if you are using webforms, a generic handler, etc...
Check out Model Binding To A List. Your Action method should be:
public ActionResult MyAction(string[] Amount, int[] Item){
// ...
}
However this will make you need to "link" the items. Alternatively create a "Item" class:
public class Item {
public string Amount { get; set; }
public int Item { get; set; }
}
And
public ActionResult MyAction(IList<Item> items){
// ...
}
And your markup should be:
<input type="hidden" name="items.Index" value="0" />
<input type="text" name="items[0].Amount" id="items[0].Amount">
<select name="items[0].Item">
<option value="1">Item 1"</option>
<option value="2">Item 2"</option>
<option value="3">Item 3"</option>
</select>
<input type="hidden" name="items.Index" value="1" />
<input type="text" name="items[1].Amount" id="items[1].Amount">
<select name="items[1].Item">
<option value="1">Item 1"</option>
<option value="2">Item 2"</option>
<option value="3">Item 3"</option>
</select>
Etc...
I believe if you have multiple fields named Amount the values will be comma delimited.
To access each one just try:
string[] amounts = Request.Form["Amount"].Split(new char[] { ',' });
Keep in mind though, the inputs are not cleaned on submission so if someone enters a comma into the text box it's going to cause issues.
Hence I'd recommend numbering them.
I ended up realising that (blush) the mechanism which JQuery uses to find the string within the cloned row (to replace) is basically regex. Thus I just needed to escape the square brackets and period. Once I did this I was able use JQuery to create form as Phil Haack's blog suggested.
Onto my next issue...!
I would number them Amount1, Amount2, Amount3 etc.
You can change the id and name attribute of the input to something like this "Amount[1]","Amount[2]","Amount[3]" (yes, the id and name attribute can contain the special chars "[" or "]"). Then in the controller, write a http request parameter parser to get back the Amounts as collections.
