My first row static of form is working fine, but when I add another one, the form is being added but I cannot obtain any value, like it would stay empty. If u need store many values - u should pass collection of objects. That means, rowIndex of next elem - will be 5.

Append input to row and table I didn't test this function. I have a similar problem when I try to access the input in a form, but I can't understand the replays. In my controller I have a model. Can you help me, please? Thank you for your help.

And sorry because I didn't explain my issue very well. I am using an ArrayList for the movies so I need to specify an index on the html page, but I don't know how to do it, because it doesn't work. Really, my case is a little bit more complex. I think that the catalog form works ok I can't be sure yet because to submit the catalog form I have to submit before the movies form because is not possible to have a catalog without movies.

In peliculaService I have the method "insertarCatalog" where I insert a new catalog I need the catalog's id for the movies and the in a for I iterate and add the movies to the catalog. So when I press this button, I can to add another movie, and when I finish to add movies to the catalog, I have to press "submit" on the catalog form to insert all the data on the database the catalog's id is generated by hibernate, and the movie's id is generated by me on the service.

I hope you can understand me, and thank you so much! There is no need in 2 models and 2 form. U can do next: 1.

I have a spring boot controller which returns a view and i wanted to change it by consuming an ajax endpoint, but at the same time get the values from the form with a modelAttribute and then send a list or multiple lists on the page and iterate through those lists with thymeleaf. Is it possible? Here is the controller:. I don't want to manipulate the page from the ajax succes part because i'm already doing that with thymeleaf when the model is sent to the page.

So what you want is to receive a Thymeleaf fragment using an ajax request. You can achieve this changing your code for the following and adding a fragment where you will add your attributes.

I just edited my answer. Now you will returning a Thymeleaf fragment with the required list. Hope it helps now.Thymeleaf is a popular server-side template engine for Java-based web applications.

In this article, you'll learn how to create HTML forms in Thymeleaf and how to handle the form submission on the backend using Spring Boot.

Spring Boot Thymeleaf Ajax Example

If you need more information on working with Thymeleaf in Spring Boot, take a look at this guide. For this article, I'll cover all the core HTML form elements such as inputs, text areas, checkboxes, radio buttons, and dropdowns. To use Thymeleaf with Spring Boot, you only need to include spring-boot-starter-web and spring-boot-starter-thymeleaf starter dependencies.

For Gradle, add the following dependencies to your build. Let us first create a simple Java model class named Project. Such a class is annotated with the Controller annotation to indicate that it is a web controller. Let us create a Spring Boot controller class called ProjectController.

As you can see above, our controller class contains two methods. It uses a Model object to expose a new Project object to the view template.

It receives a Project object that was populated by the form. Since the Project object is a ModelAttributeyou can access it in the view template and display the result. Thymeleaf templates are simply HTML static files that works both in web applications and browsers. Let us now create a Thymeleaf template named create-project.

The command object is the main form-backing bean attached to the form that contains all properties related to input fields. Generally, it is a Java model class with declared getter and setter methods.

You can easily bind an input field to a property in the bean class using the th:field attribute. The th:field attribute also allows you to define checkbox and radio button input fields. Let us add checkbox and radio buttons to the above HTML form:. Thymeleaf also allows us to show validation error messages to the user on the form and field level. To check if a specific field contains an error, you can use the fields. Here is an example that appends the error-field class when the title field contains any error:.

Alternatively, you can also use a special attribute th:errorclass that appends the specified CSS class to the HTML element if the field contains any error:.

Another way to list all errors for a specific field is by using the th:errors attribute. Global errors are not associated with any specific fields in the form. Usually, these errors are added programmatically from the backend side of the application.

To access global errors you need to pass global as a parameter to the field. Finally, create a new Thymeleaf template named result. Now execute the following command in your terminal from the root directory of the project to start the application:. Here is how it looks like:. When you fill all input fields and then click on the Save Project button, you will see the following output:.

We covered the whole process of creating an HTML form in Thymeleaf, binding fields with command object attribute, showing validation errors, handling form submission in the Spring Boot controller and displaying the result to the user.

How to post form input with complex java object using ajax.

I am working on a UI app using spring-boot-starter-web spring version 4 and Thymeleaf version 2. I display a page with a form whose th:object is a java object containing several nested objects.

The current field values are displayed properly but I can't figure out the best way to post this data back to my server. I'm not sure how to pass the updated form values to the javascript function which would make the ajax call. This also seems to lose the advantage of the thymeleaf form binding. I've seen similar questions posed in several places but I have yet to see an answer that I think would work. Re: How to post form input with complex java object using ajax.

thymeleaf ajax form submit

Thymeleaf is a server-side Java template engine. It doesn't really have anything to help you the kind of ajax calls you're talking about. Why did you choose thymeleaf if you prefer to handle things that way? In any case, you'll have to find some javascript way to turn your form into json. With thymeleaf, normally you would bind to your form as you have done with your th:object and then do a regular post -- spring takes care of the binding with ModelAttribute -- and then you do whatever you do with your data.
