Errai UI : conditions in HTML

[matic.petek]

Hi,

Is is possible to set conditions in HTML template? So you can use some block of HTML code base on state of Java variable. Or should I use DOM manipulation (like example 10.6.1.1. Composite component class).

Thank you

Sounds like you want to use a producer - Producers - Errai - Project Documentation Editor

Hi,

Thank you Anton. But I don't really think this is solution for my problem. I would like to have the some Java class for HTML template, but conditions inside HTML templates. For example :

+++++ MyTemplate.html

<form>

  <legend>Log in to your account</legend>

  <label for="username">Username</label>

  <input id="username" type="text" placeholder="Username"> 

  <#if show_input_password??>

   <label for="password">Password</label>

   <input id="password" type="password" placeholder="Password">

  </#if>

  <button>Log in</button>

  <button>Cancel</button>

</form>

+++++ MyTemplate.java

@Templated

public class MyTemplate extends Composite {

  Boolean show_input_password;

}

Hi Matic,

This isn't possible inside the template as we want our templates to be plain/standard conform HTML5 so they can be rendered in the browser directly (without having to pass them through a template engine when designing the UI).

So, you will need to do this in Java code, either by injecting a different composite (that is based on a different template) i.e. using a producer as Anton suggested or doing it programmatically.

Cheers,

Hi Christian,

  Thank you for reply. I have discussion about this with my coworker and find out the some thing - we will use different composite.
