.tooltip() is not a function

阅读更多关于 .tooltip() is not a function

问题 I am trying to use the .tooltip() that I found from the following: Jquery-ui tooltip. What I have is a rails app that has some information in a table. In separate cells. Currently you can view the full information of a cell by clicking it which opens up jquery dialog which works fine. What I am trying to add to it is so that there will be two options. 1) Click the cell which brings up jquery dialog - which works already 2) Or hover a cell which shows an overview.

问题 I have an index page with a free form comment field. The Comment field is part of another model that is not associated-- long story, part me, part user.

So, does anyone have a tutorial or advice to point me to regarding doing in place editing for an index? 回答1: What I wound up doing was: Create a row in the table that was a TextArea and assigned the

Rails separate array items with comma inside partial

阅读更多关于 Rails separate array items with comma inside partial
