dynamic-forms

问题 A problem is occurring with the angular materials mat-stepper when working with dynamic forms. For example I have a stepper with 3 steps each having there own form. The first step however uses a hidden form to determine if it is valid or not as this step can dynamically add more forms so binding all of them to the step is impossible. When you are on the first step you can create multiple forms and everything works as expected without any random validation occurring to the new forms added. The

问题 I have a bean with a List<T> : @Named @ViewScoped public class Bean { private List<Item> items; private String value; @Inject private ItemService itemService; @PostConstruct public void init() { items = itemService.list(); } public void submit() { System.out.println("Submitted value: " + value); } public List<Item> getItems() { return items; } } And I'd like to edit the value property of every item: <h:form> <ui:repeat value="#{bean.items}" var="item"> <h:inputText value="#{bean.value}" /> <

问题 I am creating a dynamic form that allows a user to add/remove text fields. While I can add text fields with no problem, I'm having difficulty removing specific text fields. Whenever I add additional text fields (say a total of 5), and try to remove any of them except for the first one (say removing field 3). All of them disappear as if the page reloaded. It's as if my jQuery code doesn't run when "Remove Field" is pressed. <form> ... <div id="answers"> <div class="form-group" id="option1">

问题 Trying to calculate a total payOffs.amount (payOffs is a FormArray). Not sure how to do it properly so the total would observe changes to current and new for amounts. Here is a plnkr that I took as a base code: http://plnkr.co/edit/nHSIsciSZNTQzQjxkXsk?p=preview <form (ngSubmit)="onSubmit()" [formGroup]="form"> <label>Name</label> <input type="text" formControlName="name" [(ngModel)]="myModel.name" placeholder="Name"> <p>Pay Offs</p> <table class="simple-table"> <tr> <th>Amount</th> <th>Date<

This XML contains information on some form fields that needs to be presented. So I created this custom DynamicField.java that has all the information we need: public class DynamicField { private String label; // label of the field private String fieldKey; // some key to identify the field private String fieldValue; //

问题 I am generating a dynamic fieldset with javascript.

问题 I generate a dynamic form starting from annotated bean. The same bean is annotated for validation using Hibernate Validator. The form is correctly rendered but when the form is submitted the validation step it's not executed. If I write the same form with jsf tag the validation works properly. Any idea? The form page: <body> <ui:composition template="/template/basetheme_one_col.xhtml"> <ui:define name="title">#{__g4cController.entityClassName}</ui:define> <ui:define name="main_area"> <h2>#{_
