node.js - End of multiple streams (stream inside loop) -


im working on project , have compress several directories, , use compressed files call function. that, i'm using https://github.com/npm/fstream , https://github.com/npm/node-tar libraries.

 var fstreamr = require('fstream').reader;  var fstreamw = require('fstream').writer;  var tar = require('tar');   (var comp in components){       // in order build images docker api, directory      // containing dockerfile , code must compressed      // tar.      var fr = fstreamr({'path':components[comp],'type':'directory'})      var fw = fstreamw({'path':'../../'+comp+'.tar'})      fr       .pipe(tar.pack())       .pipe(fw)      fw.on('finish',function(){           //do      }) }

so comp changes in each iteration , create new tar file. problem need tar completed before calling function uses it.

i have 2 issues here. first one: callback @ event listener event 'finish' never called.

the second one: if working, callback launched value of comp corresponding for iteration in event listener called?.

i appreciate suggestions or other ideas work around problem. in advanced.

in regards first issue, try listening fw.on('close') instead. looks source may emitting close , not finish.

css - Make div keyboard-scrollable in jQuery Mobile? -

from can tell, although jquery-mobile-powered pages can contain divs overflow set scroll or auto, , these divs can scrolled one-screen bar or mouse wheel, cannot scrolled using arrow keys, page-up/page-down, or home/end. instead, official "page" div (with data-role="page") absorbs input. perhaps other divs can't acquire focus, i'm not sure. is there way around this? edit: jsfiddle of simple example: https://jsfiddle.net/qogz0shx/ <script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.4/jquery.min.js"></script> <script src="https://ajax.googleapis.com/ajax/libs/jquerymobile/1.4.5/jquery.mobile.min.js"> </script> <link rel="stylesheet" href="https://code.jquery.com/mobile/1.4.5/jquery.mobile-1.4.5.css"/> <style> #outer { overflow:scroll; height: 50vh; width: 50vw; } #inner { height: 500vh; width: 500vw; } &l
