search

问题 i want to know as how to search or filter records in a gridview dynamically based on the character(s) entered on a textbox. What is the best way to achieve this? Any sample codes or examples will be really helpful. 回答1: The trick here is to make databind only when the text change on the search box, but you must always set the datasource select command code . So you add a text box, and a button that say, submit, and you have the following: OnPageLoad -> if(SearchContron.Text.Length > 0)

I assume I could somehow link_to a method which contains the query code, but how could I use specific search params? Let's say I only want to search by name for matching instances of one model. Thanks in advance! 回答1: the simple way to do it is Model.find(:all, :conditions => ['name LIKE ?', "%#{search}%"]) in View <% form_tag projects_path, :method => 'get'

问题 The default search using the DuckDuckGo API returns only the results on the first page (around 25 I guess). Is there any way to get more results or navigate to the 2nd, 3rd pages of the search results? Websites like Faroo have a parameter called s (which stands for start) which can be set to 1 if we want the first 10 results, to 11 if we want the next 10 results and so on. Is there something like that for DuckDuckGo, too? 回答1: According to DuckDuckGo Search API documentation, all the
