问题 I have an event form with some nested attribute models. The additional models are rendered after a client is selected from a select box. An observer watches and calls a controller action which renders a partial containing the fields_for nested models. The issue I'm having is that I can't pass the event 'form' block to the newly rendered partial - at least I can't figure out how... The code below raises the error: "wrong number of arguments (0 for 1)". Any help or suggestions are appreciated.

问题 The site I'm working on uses Prototype 1.6.1. Its Event.stop() doesn't work in IE9. I know that Prototype 1.7 fixes the problem. However, is there a walk-around if I cannot upgrade to Prototype 1.7? I need the site to be compatible with IE 7, 8 and 9 (as well as Chrome, Firefox, etc). Thanks! EDIT: I tried event.preventDefault() and it doesn't work for me in IE 9. Here is an example: http://jsfiddle.net/garthcn/AdR7g/ It works in jsfiddle/Chrome/Firefox. If you paste the code to an HTML file

问题 Not wanting to re-invent the wheel or anything, I was wondering if there's a plugin out there a field or form validation plugin that works with Prototype that you can recommend from your own experience and why? 回答1: I like Ben Keen's Really Simple Validation component. Features I like: All the validation rules can be kept within javascript so you're not adding class="required" to your HTML code. You can display error messages in a javascript alert box or with HTML text. Adding your own

问题 What's the advantage of passing data as parameters vs part of the URL in an Ajax GET request? Using parameters: var ajax = new Ajax.Request('server.php',{ parameters: 'store=11200&product=Meat', onSuccess: function(myData){whatever} }); Using URL: var ajax = new Ajax.Request('server.php?store=11200&product=Meat',{ onSuccess: function(myData){whatever} }); 回答1: One advantage to using the parameters argument is that you can pass it a Hash -like object instead of as a string. (If you do this,
