best and simple way to use native java Script which is one liner code.

document.querySelector('#id').click();

Just add 'id' to your html element like

<button id="myId1" ng-click="someFunction()"></button>

check condition in javascript code

if(condition) { document.querySelector('#myId1').click(); }

So it was a simple fix  Just had to move the ng-click to a scope click handler    lt input id  upload      type  file      ng-file-select  onFileSelect  files       style  display  none   gt    lt button type  button      ng-click  clickUpload    gt Upload lt  button gt      scope clickUpload   function        angular element   upload   trigger  click

I just came across this problem and have written a solution for those of you who are using Angular  You can write a custom directive composed of a container  a button  and an input element with type file  With CSS you then place the input over the custom button but with opacity 0  You set the containers height and width to exactly the offset width and height of the button and the input s height and width to 100  of the container   the directive  angular module  myCoolApp      directive  fileButton   function          return         templateUrl   components directives fileButton fileButton html         restrict   E         link  function  scope  element  attributes             var container   angular element   file-upload-container            var button   angular element   file-upload-button             container css               position   relative               overflow   hidden               width  button offsetWidth              height  button offsetHeight                                     a jade template if you are using jade  div class  file-upload-container        button class  file-upload-button         input file-upload class  file-upload-input   type  file   onchange  doSomethingWhenFileIsSelected         the same template in html if you are using html   lt div class  file-upload-container  gt      lt button class  file-upload-button  gt  lt  button gt      lt input class  file-upload-input  id  file-upload  type  file  onchange  doSomethingWhenFileIsSelected      gt    lt  div gt    the css   file-upload-button       margin-top  40px      padding  30px      border  1px solid black      height  100px      width  100px      background  transparent      font-size  66px      padding-top  0px      border-radius  5px      border  2px solid rgb 255  228  0        color  rgb 255  228  0      file-upload-input       position  absolute      top  0      left  0      z-index  2      width  100       height  100       opacity  0      cursor  pointer

If you are getting  scope binding errors make sure you wrap the click event code on a setTimeout Function   VIEW   lt input id  upload      type  file      ng-file-select  onFileSelect  files       style  display  none   gt    lt button type  button      ng-click  clickUpload    gt Upload lt  button gt    CONTROLLER   scope clickUpload   function        setTimeout function            angular element   upload   trigger  click           0

If your input and button are siblings  and they are in your case OP     lt input id  upload      type  file      ng-file-select  onFileSelect  files       style  display  none   gt    lt button type  button  uploadfile gt Upload lt  button gt    Use a directive to bind the click of your button to the file input like so   app directive  uploadfile   function          return         restrict   A         link  function scope  element             element bind  click   function e                angular element e target  siblings   upload   trigger  click

I think you are over complicated things a bit  Do you really need to trigger a click on the input from your button    I suggest you just apply a proper style to your input and the ngFileSelect directive will do the rest and call your onFileSelect function whenever a file is submitted    input file       cursor  pointer      direction  ltr      font-size  23px      margin  0      opacity  0      position  absolute      right  0      top  0      transform  translate -300px  0px  scale 4

Simply have them in the same controller  and do something like this   HTML    lt input id  upload      type  file      ng-file-select  onFileSelect  files       style  display  none   gt    lt button type  button      ng-click  startUpload    gt Upload lt  button gt    JS   var MyCtrl       scope     upload   function  scope   upload       scope files          scope startUpload   function        for  var i   0  i  lt   scope files length  i             upload  scope files i                  scope onFileSelect   function  files          scope files    files             This is  in my opinion  the best way to do it in angular  Using jQuery to find the element and trigger an event isn t the best practice
