Javascript sleep delay wait function

Question

Sorry if this question has already been asked here before  I could not find a suitable answer   I am wanting to create a JavaScript sleep delay wait function that I can call anywhere in the script  like jQuery s  delay    I am not able to use setTimeout  as I have a script that is generated by php  and so am not able to put it into two different functions  with the timeout in the middle  I need to create a function that allows me to do  alert  time started    sleep 4000   alert  time up      I really do not want to use jQuery

You could use the following code  it does a recursive call into the function in order to properly wait for the desired time   function exportar page miliseconds totalpages        if  page  lt   totalpages                nextpage   page   1          console log  fnExcelReport    page      nextpage      nextpage      miliseconds      miliseconds      totalpages      totalpages            fnExcelReport page           setTimeout function                exportar nextpage miliseconds totalpages             miliseconds

You cannot just put in a function to pause Javascript unfortunately   You have to use setTimeout    Example   function startTimer          timer start        setTimeout stopTimer 5000      function stopTimer          timer stop        EDIT   For your user generated countdown  it is just as simple     HTML    lt input type  number  id  delay  min  1  max  5  gt    JS     var delayInSeconds   parseInt delay value   var delayInMilliseconds   delayInSeconds 1000   function startTimer          timer start        setTimeout stopTimer delayInMilliseconds      function stopTimer          timer stop      Now you simply need to add a trigger for startTimer    such as onchange

The behavior exact to the one specified by you is impossible in JS as implemented in current browsers  Sorry   Well  you could in theory make a function with a loop where loop s end condition would be based on time  but this would hog your CPU  make browser unresponsive and would be extremely poor design  I refuse to even write an example for this       Update  My answer got -1 d  unfairly   but I guess I could mention that in ES6  which is not implemented in browsers yet  nor is it enabled in Node js by default   it will be possible to write a asynchronous code in a synchronous fashion  You would need promises and generators for that   You can use it today  for instance in Node js with harmony flags  using Q spawn    see this blog post for example  last example there

Here s a solution using the new async await syntax   async function testWait         alert  going to wait for 5 second        await wait 5000       alert  finally wait is over       function wait time        return new Promise resolve   gt            setTimeout      gt                resolve               time                  Note  You can call function wait only in async functions

You can use this -  function sleep milliseconds        var start   new Date   getTime        for  var i   0  i  lt  1e7  i              if   new Date   getTime   - start   gt  milliseconds               break

You will have to use a setTimeout so I see your issue as     I have a script that is generated by PHP  and so am not able to put it into two different functions   What prevents you from generating two functions in your script   function fizz         var a      a    buzz          sleep x desired     a    complete       Could be rewritten as  function foo         var a     variable raised so shared across functions below     function bar        consider this to be start of fizz         a    buzz           setTimeout baz  x      start wait          code split here for timeout break     function baz        after wait         a    complete            end of fizz     bar       start it     You ll notice that a inside baz starts as buzz when it is invoked and at the end of invocation  a inside foo will be  complete    Basically  wrap everything in a function  move all variables up into that wrapping function such that the contained functions inherit them  Then  every time you encounter wait NUMBER seconds you echo a setTimeout  end the function and start a new function to pick up where you left off
