I am using codeigniter for a project.
I have a table with rows added dynamically through jquery append.
So when I click on a button submit, it post values for all the rows values to the controller, but I am not sure how to do that.
My table row is like this
<td>
<input type="text" class="createWOBlockBG large ui-autocomplete-input" name="basefabrics" id="basefabrics1" autocomplete="off">
</td>
I do not want to use ajax calls.. How do I pass many of the inputs from the view to the controller?Thanks in advance for the help.
If your table with rows and as mentioned submit button is inside a form
then specify action attribute of your form to the controller where you want to access your values
and in the controller you can get the values as follows
$value = $this->input->post('name_of_your_input');
considering your input
$base_fabrics = $this->input->post('basefabrics');
if your form action is calling the same controller method which loaded the view, you can check for the click of submit button and then fetch values
if ($this->input->post('name_of_submit_btn'))
{
$base_fabrics = $this->input->post('basefabrics');
}
EDIT: if all your inputs have same name then better name it as name="basefabrics[]"
so that when you fetch the value
$base_fabrics = $this->input->post('basefabrics');
$base_fabrics will be an array

im using spring mvc framework with thymeleaf template engine
the problem is , i have 1 page with multiple check box iterated sing thymeleaf th:each iterator.When i clicked multiple check boxes i want to pass check box values to the controller method..
html content
<table>
<tr th:each="q : ${questions}">
<h3 th:text="${q.questionPattern.questionPattern}"></h3>
<div>
<p >
<input type="checkbox" class="ads_Checkbox" th:text="${q.questionName}" th:value="${q.id}" name="id"/>
</p>
</div>
</tr>
</table>
*Controller*
#RequestMapping(value = Array("/saveAssessment"), params = Array({ "save" }))
def save(#RequestParam set: String, id:Long): String = {
var userAccount: UserAccount = secService.getLoggedUserAccount
println(userAccount)
var questionSetQuestion:QuestionSetQuestion=new QuestionSetQuestion
var questionSet: QuestionSet = new QuestionSet
questionSet.setUser(userAccount)
questionSet.setSetName(set)
questionSet.setCreatedDate(new java.sql.Date(new java.util.Date().getTime))
questionSetService.addQuestionSet(questionSet)
var list2: List[Question] = questionService.findAllQuestion
var limit=list2.size
var qustn:Question=null
var a = 1;
for( a <- 1 to limit ){
println( a );
qustn= questionService.findQuestionById(a)
questionSetQuestion.setQuestion(qustn)
questionSetQuestion.setQuestionSet(questionSet)
questionSetQuestion.setCreatedDate(new java.sql.Date(new java.util.Date().getTime))
questionSetQuestionService.addQuestionSetQuestion(questionSetQuestion) } "redirect:/teacher/Assessment.html" }
I think you pretty much have it. With a checkbox, you can only send one piece of information back with the form...that being the value. So if you are trying to determine which checkboxes are checked when the user clicks the submit button, then I would have the checkboxes all use one name...like "id" (exactly like you have). Value is the actual id of the question (again like you have). Once submitted, "id" will be a String array which includes all the values of the checkboxes that were checked.
So your controller method needs to take param called "ids" mapped to parameter "id" which is a string[]. Now for each id, you can call questionService.findQuestionById.
(I'm not a Groovy guru so no code example sry :)
I have used JSTL with JSP and thymeleaf was something new. I read the THYMELEAF documentation.
There is a section which explains multi valued check boxes.
<input type="checkbox"
class="ads_Checkbox"
th:text="${q.questionName}"
th:value="${q.id}" name="id"/>
In the above code we are not binding the value to the field of the command object. Instead try doing this
<input type="checkbox"
class="ads_Checkbox"
th:text="${q.questionName}"
th:field="*{selectedQuestions}"
th:value="${q.id}" />
here the selectedQuestions is an array object present in the spring command object.
i am working web application on struts 1.3 in netbeans i have two dropdownlist say A and B now i have no probl1em in populating these dropdowns on jsp load ,now user select one value from say dropdown A and value user selected say it is 1 and for another dropdown say B user selected value which is 2 and now user will save these values in database now my requirement is that when we go in edit mode for that when page loads dropdownlist A should have value 1 as preselected and dropdownlist B should have value 2 as preselected. and these values are coming from database
my jsp page
1 dropdown
<tr>
<td> <html:select name="RoomForm" property="location"onchange="getFloorDropdown(this.value);" >
<html:option value="0">Select Location</html:option>
<html:optionsCollection name="RoomForm"
property="list" value="id" label="name" />
</html:select>
<td>
</tr>
RoomForm:-name of my form bean in requst scope
list:-Arraylist collection
id:-it is property in Arraylist which is list having getter and setter in bean
name:-it is property in Arraylist which is list having getter and setter in bean
2 dropdown
<select name="floor" >
<option value="0">Select Floor</option>
</select>
how should i do how select a preselected values in both downdroplist when this form opens in edit mode
any hint will be a great help for me
Zohaib,
In the action that is responsible for retrieving the information from the database, populating the relevant ActionForm and finally loading the Edit view, the ".location" property of that ActionForm must be populated with the value stored in the database. In the JSP, you are going to associate that ActionForm instance as the form backing object. Struts will automatically do the rest, i.e. ensuring that the correct option shows as selected.
HTH.

I'm using ASP.NET MVC3 and I was wondering if there's any way to create a listbox that contains the values which I would like my model to have.
Using #Html.ListBoxFor will only store the selected items into the model when the form is submitted rather than all the items in the listbox. I plan on using javascript to add items from another textbox.
Thanks
You are not clear, but are you trying to POST values back? If so, then they must be selected (i.e. active) form values in order to POST. If you use JavaScript to add options to a listbox (HTML select> then these don't post. You would need a multi-select enabled select and then flag each value you want to submit as selected.
To get values back they need to POST in some manner.
No. This has nothing to do with MVC3. This is a limitation of the HTTP model. When a form is posted, the browser only posts the selected value. It does not post the other elements of the select list.
MVC must work within the framework of the way the browsers work, and this can't be changed.
Yes, you can do this. You need a couple things to make this work though, it can be troubling.
In view:
//generate list box with
<select id="NAMEOFLISTBOX" name="NAMEOFLISTBOX" multiple="multiple">
Okay, here is the part that most people miss. The controller will only collect selected items if they are actually designated to be selected. Therefore, where your submit button is you need to include some javascript.
<input type="submit" value="DO WORK" onclick="selectLISTBOXITEMS()" />
Script:
function selectLISTBOXITEMS(){
var curList = document.getElementById("NAMEOFLISTBOX");
for (var i = 0; i < curList.length; i++) {
curList.options[i].selected = true;
}
}
In controller:
[HttpPost]
public ActionResult controllerName(List<string> NAMEOFLISTBOX)
{
foreach(string s in NAMEOFLISTBOX)
{
//do work
}
return RedirectToAction("controllerGet");
}
Not impossible, but the first time I did this it took a while to figure out why nothing was being sent.
We have a ASP.NET MVC 3 application that uses unobtrusive jQuery validation. The page allows to add children objects to the model in the same go. The <form> contains a grid for the children, and some input fields for adding new children.
Simplified example with Issue as the Model and Subtasks as the children:
Issue.cshtml -> Defines the form and includes fields for the issue as well as its subtasks.
#model Issue
#using (Html.BeginForm("Create", "Issues", FormMethod.Post, new { id = "mainForm" })
{
#Html.TextBoxFor(model => model.Summary)
#Html.Partial("SubtaskFields", new Subtask())
#Html.Partial("SubtasksGrid", model.Subtasks)
}
SubtaskFields.cshtml:
#model Subtask
#Html.TextBoxFor(model => model.Summary)
<button id="add">Add</button>
SubtasksGrid.cshtml:
#model IEnumerable<Subtask>
<table>
#foreach (var subtask in Model)
{
<tr>
<td>
#subtask.Name
<input type="hidden" name="Subtasks[#subtask.Index].Name" value="#subtask.Name"/>
</td>
</tr>
}
</table>
The point is, when submitting the form, only the properties of the issue (Issue.Name, e.g.), plus the hidden fields for the children (Subtask.Name, e.g.) should be validated and submitted.
We have some javascript code that hooks on the "add" button, and adds a new subtask based on the values in the SubtaskFields.cshtml partial view. That script validates the input fields first. In order for this to work, we use the TextBoxFor etc. html helpers for the SubtaskFields.cshtml, too, rendering a dummy/default Subtask object (new Subtask()). Our javascript the uses $("#mainForm").validate().element(...) to validate the SubtaskFields before adding a new subtask.
The big problem with this approach is that the jQuery unobtrusive validation framework automatically hooks on the submit button and validates all fields within the form before submitting the form. I.e., even the subtask fields are validated. This does not make any sense. Say that the subtask name is mandatory (which means the user can only click on "add" if he has filled in a subtask name). But if the user does not click on "add", the values in the Subtask Fields don't have any meaning and can in particular be left blank. In this case, in our current setting, jQuery validation fails because a mandatory field was left blank.
How can this be solved?
This is what we've come up with:
Add an attribute to all subtask fields (which should not be validated when submitting the form), e.g. "data-val-ignore".
Set the ignore setting on the form's validator to "[data-val-ignore]"
For the add button, in order to validate the subtask fields (which are normally ignored), iterate over them, and for each field, remove the attribute, re-parse to genereate the rules, execute validation, add the attribute, parse one more time.
Ad 2:
$(document).ready(function () {
$.data($('form')[0], 'validator').settings.ignore = "[data-val-ignore]";
});
Ad 3:
$(allSubtaskFields).each(function() {
$(this).removeAttr("data-val-ignore");
$.validator.unobtrusive.parseElement(this, false);
if (!$("mainForm").validate().element($(this))) { result = false; }
$(this).attr("data-val-ignore", "true");
$.validator.unobtrusive.parseElement(this, false);
});
I would suggest moving #Html.Partial("SubtasksGrid", model.Subtasks) outside of your form, and either having it in a single separate form, or have the partial generate a form for each grid row.
This will address your validation problems with your main form, and should also permit you to simplify validation of each row in SubTasksGrid.
To validate part of the form, wrap the section or the controls you want to validate into a div with an #id or .class and do the following:
var validator = $("#myForm").validate();
var isValid = true;
$("myDivToBeValidated").find("*[data-val]").each(function (indx, elem) {
if (!validator.element(elem)) {
isValid = false;
}
});
//this part of form is valid however there might be some other invalid parts
if (isValid)
//do your action, like go to next step in a wizard or any other action
goToNextStep();
I hope it is clear, if not please leave a comment. For more info about jQuery validation plugin and element() function, check this
Looks like you are working against the MVC egine here.
I would use Editor templates and Display templates, EditorFor template for the stuff you wanna validate and post, and Display template for the stuff you dont wanna post and validate.. If you have a TextBoxFor in the display template make sure its binding property has no Required attribute, and if its a value type make it nullable.
I am doing a edit operation on a record in Grid . One of the column is DropDownValue.
When I go to Edit View , depending upon this dropdownvalue , I make few fields editable and readable. And , One more point is here, I didnt select the dropdown Yet, But whatever its value selected before is the one which I should retrieve. I know I have to use jQuery .But I didnt exact Syntax to do tht.
Here is my dropdown
<div id="dvstatus">
#Html.DropDownListFor(model => model.Study.StudyStatusId, Model.StatusSelectList, new { id = "ddlStatus" })
</div>
NOT SELECTED VALUE, BUT THE VALUE WITH WHICH IT IS LOADED
My requirement is how to get the dropdown value item , when it is loaded onto .cshtml
If you're not referring to the selected value of the dropdown then just pass the value from the controller to your view using your model if you're using a strongly-typed view or pass it some other way like using ViewBag and just set the value when it's passed on view.
You can add a hidden field to save the initially loaded value. Eg
<div id="dvstatus">
#Html.HiddenFor(model => model.Study.StudyStatusId)
#Html.DropDownListFor(model => model.Study.StudyStatusId, Model.StatusSelectList, new { id = "ddlStatus" })
</div>
Then you can use java script to compare current value of the drop down and the value of the hidden field(which has the initial value).
