javascript - Place cursor at the end of text on keyup -


i'm making same functionality command line has. when enter commands , press key button, presented previous command.

now have working , works fine i've encountered 1 small problem.

the problem encounter when pressing up key, cursor placed @ beginning of command, while when using down button, cursor placed @ end of comand.

expected behaviour cursor placed @ end both.

what makes different other questions?

  • the focus on input field.
  • it work down button

settimeout(function() {  var inputs = document.queryselectorall('input');    inputs[0].onkeydown = function(e){    //keyup    if(e.keycode == 38) {      inputs[inputs.length-1].value = 'up pressed';    }        if(e.keycode == 40 ) {        inputs[0].value = 'down pressed';    }  }  }, 1000);

settimeout(function() {  var inputs = document.queryselectorall('input');    inputs[0].onkeydown = function(e){    //keyup    if(e.keycode == 38) {      // placed here, prevents key's default behaviour go @ end of input text      e.preventdefault();      inputs[inputs.length-1].value = 'up pressed';    }        if(e.keycode == 40 ) {        inputs[0].value = 'down pressed';    }    }  }, 1000);

What is happening when Matlab is starting a "parallel pool"? -

running parallel cpu processes in matlab starts command parpool() according documentation , function: [creates] special job on pool of workers, , [connects] matlab client parallel pool. this function takes bit of time execute, on order of 30 seconds. in other multi-cpu paradigms openmp, parallel execution seems totally transparent -- i've never noticed behavior analogous matlab (granted i'm not experienced parallel programming). so, happening between time parpool() called , when finishes executing? takes long? parallel computing toolbox enables run matlab code in parallel using several different paradigms (e.g. jobs , tasks, parfor , spmd , parfeval , batch processing), , run either locally (parallelised across cores in local machine) or remotely (parallelised across machines in cluster - either 1 own, or 1 in cloud). in of these cases, code run on matlab workers , copies of matlab without interactive desktop. if you're intending run on remo...
