Overriding placeholder text value in custom FormBuilder

rubyonrails-talk

Greetings,

I have a custom FormBuilder class I've created that inputs a placeholder text value on a text_field. It works great unless a user has errors in the form. In that case, the user's previously submitted values are overridden by my FormBuilder's placeholder value.

How can I override the placeholder value with the user's submitted values when rendering an InvalidRecord error?

My code is here for reference: Parked at Loopia

Thanks for the help.

Hi Justin,

Isn't it enough to only set the content if the field is blank? i.e., wrap your javascript calls to placeholder() in "if (this.value == '') { ... }" (or make placeholder itself check the condition), and set the :value option to the placeholder text only if the value is blank? The value can be obtained with `object.send(method)' in your form builder method.

I must admit as a user, though, I'm not usually a fan of "placeholder text."

Hope this helps, George.
