I use a list box and its item comes from the database i looped it over using while loop. All i want is when I select an item from the dropdown listbox, i can also get other selected item value from the database. Like in the picture, if i select an item in the drop down i need to get its quantity from the database. Thanks

  • Native PHP? You mean Core PHP? Ok then you can do. there are 3 methods. 1.using AJAX and 2.using pre-loaded Javascript Array and 3. Add a custom Data-Property. Choose a method (It depends on how large is your data)

You can try like -




  1. Try getting selected item's div class. Suppose could be "selected"


  2. Get div value by below -



    var selectedListval = $("#ddlist").find('.selected').val();



  3. Do null check for selectedListval and execute ajax call to function - which will serve purpose of fetching quality of selected dropdown item Refer http://api.jquery.com/jquery.ajax/
    for ajax syntax.


  4. after null check ,bind Quantity value to the Quantity textbox.



Hope this helps you.

count number of partitions of a set with n elements into k subsets

up vote 6 down vote favorite 1 This program is for count number of partitions of a set with n elements into k subsets I am confusing here return k*countP(n-1, k) + countP(n-1, k-1); can some one explain what is happening here? why we are multiplying with k?

A CLEAN and SIMPLE way to add appendices to Table of Contents and bookmarks

Image
0 I found a lot of questions abount appendices and ToC. Many users want appendices to be grouped in an Appendix part, however some problems arise with ToC, hyperref, PDF viewer bookmarks, and so on. There are different solutions which require extra packages, command patching and other extra code, however none of them satisfies me. I almost found an easy way to accomplish a good result, where appendices are added to bookmarks in the right way and hyperref links point to the right page. However, the number of the "Appendix" part page is wrong (it's the number of appendix A). Is there any EASY way to fix that? This is a MWE: documentclass{book} usepackage[nottoc,notlot,notlof]{tocbibind} usepackage{hyperref} begin{document} frontmatter tableofcontents mainmatter part{First} chapter{
