best_in_place使用：display_as-如何更新 <input> 以及

Question

I've got a best_in_place form where I am doing some post-processing of the data that gets submitted. It's a series of times, and I'm formatting them into a consistent format before saving. How do I get the updated value to be shown on the form after saving?

Answer 1

I could only find a slightly hacky way of doing this. First, set the display_as parameter on the form helper to be the same as the actual attribute being displayed.

= best_in_place @post, :name, type: :input, :display_as => :name

Then, add a javascript handler for best_in_place:success

$(document).on('best_in_place:success', function(e, data) {
  $(this).data('bestInPlaceEditor').original_content = data['display_as'];
});

When the post is saved and the name attribute is updated, the new value will be returned as JSON: it will look like {"display_as": "updated post name"} . This javascript gets the value that is returned and sets it to the BIP editor's original_content attribute. When BIP renders the input (when you click on the post's name to edit it), the value of original_content is displayed.

Tested using best_in_place 2.1.0. The relevant code in best_in_place.js is:

if (response !== null && response.hasOwnProperty("display_as")) {
  this.element.attr("data-original-content", this.element.text());
  this.original_content = this.element.text();
  this.element.html(response["display_as"]);
}

Here this.element is the that display when the field is not being edited. So, it's getting set with a different value to what original_content (which is what the gets when rendered) is. I'm not sure if this is intended or a bug in best_in_place.
