JQuery setTimeout not working

Question

I m still new to JQuery   on the way to getting my ajax example to work i got stalled with setTimeout   I have broken it down to to where it should add     to the div every second   The relevant code is in two files   index html   lt html gt  lt head gt   lt script type  text javascript  src  jquery js  gt  lt  script gt   lt script type  text javascript  src  myCode js  gt  lt  script gt   lt  head gt   lt body gt   lt div id  board  gt Text lt  div gt   lt  body gt   lt  html gt    and myCode js   function         document  ready function    update           function update                board   append             setTimeout  update     1000                  the myCode js file works alright and  update    runs the first time through but never again

SetTimeout is used to make your set of code to execute after a specified time period so for your requirements its better to use setInterval because that will call your function every time at a specified time interval

setInterval function             board   append          1000     You can use clearInterval if you wanted to stop it at one point

You ve got a couple of issues here   Firstly  you re defining your code within an anonymous function  This construct    function                  does two things  It defines an anonymous function and calls it  There are scope reasons to do this but I m not sure it s what you actually want   You re passing in a code block to setTimeout    The problem is that update   is not within scope when executed like that  It however if you pass in a function pointer instead so this works    function         document  ready function    update          function update              board   append           setTimeout update  1000                    because the function pointer update is within scope of that block   But like I said  there is no need for the anonymous function so you can rewrite it like this     document  ready function    update        function update            board   append         setTimeout update  1000             or    document  ready function    update        function update            board   append         setTimeout  update     1000             and both of these work  The second works because the update   within the code block is within scope now   I also prefer the   function           shortened block form and rather than calling setTimeout   within update   you can just use setInterval   instead     function       setInterval update  1000        function update           board   append           Hope that clears that up

This accomplishes the same thing but is much simpler     document  ready function              board   delay 1000  append             You can chain a delay before almost any jQuery method
