Try to use jQuery instead of   sign when calling the function  it worked in my case as you can see below   jQuery noConflict     jQuery   myModal   modal  show       jQuery noConflict     because when jQuery   myModal   modal  show    doesn t work  it s caused by having included jQuery twice  Including jQuery 2 times makes modals not to work  and it would resolve the problem in that case  as in my case it is repeating    Further you can go to this link  Bootstrap Model Window Not Showing by Calling Through JQuery

If you use links s onclick function to call a modal by jQuery  the  href  can t be null   For example            lt a href    onclick  openModal    gt Open a Modal by jQuery lt  a gt                   lt script type  text javascript  gt   function openModal             myModal   modal              lt  script gt    The Modal can t show  The right code is     lt a href     onclick  openModal    gt Open a Modal by jQuery lt  a gt

Most often  when     myModal   modal  show    doesn t work  it s caused by having included jQuery twice  Including jQuery 2 times makes modals not to work   Remove one of the links to make it work again   Furthermore  some plugins cause errors too  in this case add   jQuery noConflict         myModal   modal  show

Try      myModal   modal  toggle     To open or close the modal with id myModal   If the above is not working then it means bootstrap js has been overridden by some other js file  Here is a solution  1 - Move bootstrap js to the bottom so that it will override other js files   2 - Make sure the order is like below   lt script src  plugins jQuery jquery-2 2 3 min js  gt  lt  script gt   lt  -- Other js files -- gt   lt script src  plugins jQuery bootstrap min js  gt  lt  script gt
