  • grayscaling images and refering the original image back.

    - by dilip
    I know how to grayscale an image. I am using jquery accordion and I have images on every accordion header. I want to change the image to grayscale when the accordion is active and change the image back to its original form when the accordion is not active. I am using the event accordionChange. The problem is that I am not able to save the original image. Please help. Also after grayscaling I tried to give the original src directly as document.getElementById("imgId").src = "images/pic.jpg"; This is not working.

  • T-SQL stored procedure to return google style "suggested" search results

    - by stephen776
    Ok, using SQL Server 2008. On my web page I have a textbox with jQuery-UI AutoComplete hooked up. Now I need a stored procedure to search across all columns of a single table(or multiple joined tables I suppose) for a search string coming from the textbox/autocomplete AJAX call, and return "suggested" search strings. I am using the AdventureWorks db for testing(Products table) So for example, the product table has columns for product name and product number(among others) and I want to return suggested search strings based on user input where they may enter a product name and/or a product number. I have it working across a single column which was simple. Any ideas?

    I need to serve images securely to validated users only (i.e. they can't be served as static files). I currently have the following Python view in my Django project, but it seems inefficient.

  • Cakephp: Extend search capability to hasMany Relationship

    - by Chris
    I have two models: Car hasMany Passengers Passenger belongsTo Car I want to implement a search using Cake Search. The user should input a number and the searchengine should return all cars that have less than this number passengers. In my search form: echo $form->input('passengers', array('label' => 'Passengers', 'div' => false)); In my Car model: public $filterArgs = array( array('name' => 'passengers', 'type' => 'int'), ); In the controller: public $presetVars = array( array('field' => 'passengers', 'type' => 'int') } I thought of adding a function to the model that returns the number of passengers: function countPassengers(){ return(count($this->Car->Passenger)); //Not sure if this works } And how to I implement this search criteria?: return all Cars where countPassengers()<passenger

  • JQuery Tabs; Google Map is shown with just one tile

    - by java_dude
    Yes this problem is common and I have seen numerous solution on this site but none of them were helpful. I know that re-sizing will fix the problem. Not a jQuery expert and I don't know how to re-size the map after the page has been loaded and Headline 3 is active. I have created a JFiddle example. Any help is appreciated. http://jsfiddle.net/KhwZS/1300/ Thanks Ignore the top comment and the links provided by @Dr.Molle as these links do not provide the solution that I have been looking for, check out the solution I have accepted.
