jQuery trigger file input

Question

Am trying to trigger an upload box (browse button) using jQuery.
The method I have tried now is:

$(\'#fileinput\').trigger(\'click\');   

Answer 1

this worked for me:

JS:

$('#fileinput').trigger('click'); 

HTML:

CSS:

.hiddenfile {
 width: 0px;
 height: 0px;
 overflow: hidden;
}

The Idea is that you overlay an invisible huge "Browse" button over your custom button. So when the user clicks your custom button, he's actually clicking on the "Browse" button of the native input field.

HTML:

  
  Click Me!

CSS:

div#mybutton {

  /* IMPORTANT STUFF */
  overflow: hidden;
  position: relative;   

  /* SOME STYLING */
  width:  50px;
  height: 28px;
  border: 1px solid green;
  font-weight: bold
  background: red;
}

div#mybutton:hover {
  background: green;
}

input#myfile {
  height: 30px;
  cursor: pointer;
  position: absolute;
  top: 0px;
  right: 0px;
  font-size: 100px;
  z-index: 2;

  opacity: 0.0; /* Standard: FF gt 1.5, Opera, Safari */
  filter: alpha(opacity=0); /* IE lt 8 */
  -ms-filter: "alpha(opacity=0)"; /* IE 8 */
  -khtml-opacity: 0.0; /* Safari 1.x */
  -moz-opacity: 0.0; /* FF lt 1.5, Netscape */
}

JavaScript:

$(document).ready(function() {
    $('#myfile').change(function(evt) {
        alert($(this).val());
    });
});
