Is there a way to restrict users from entering characters beyond a certain limit in oracle jet

Question

Is there a way to restrict users from entering characters beyond a certain limit in oracle jet? The maxlength attribute of input html element doesn't let users enter beyond the maxlength characters.

Answer 1

Edit based on comments:

Unfortunately OJET does not provide a way to do that. It could be done through jQuery like this:

HTML

<oj-input-text id="text-input" value="{{value}}"></oj-input-text>

JS

this.value = ko.observable("Green");
self.bindingsApplied = function(){
    $($('#text-input').find('input')[0]).attr('maxlength','5');
};

bindingsApplied is a method implicitly called by OJET after the viewModel binds with the HTML. It is similar to $(document).ready();

Original answer:

Yes there is. Not only can you limit the number of characters allowed, you can provide custom error messages as well - or let OJET display the default - when you don't meet the requirements.

HTML:

<oj-input-text value="{{value}}"
              validators="[[validators]]"
              placeholder="up to 10 characters">
</oj-input-text>

JS:

self.validators = ko.computed(function()
{
  return [{
    type: 'length', 
    options: {max: 10,
              messageSummary : {
        tooLong: 'Too Long: Too many characters'
      }}}];
});
