Trigger File Input Dialog

Question

How can I auto trigger file input? ie. in the link below I want to trigger upload button on load DEMO

Solution 1:

File input can't be automatically triggered in onload due to security purpose. It can't be fired without any user interaction. It is very disgusting when a page activates anything itself when the page loads.

By the way. You can use label instead of button like following:

<labelfor="test">Upload</label>

Solution 2:

$("document").ready(function() {
    setTimeout(function() {
        $("#test1").trigger('click');
    },10);

    $('#test1').click(function(){
        alert('hii');
    })
});

click event triggerd.

Solution 3:

you can write something like this

$(document).ready(function(){
    $("input#test").click();
});

this should work fine

Solution 4:

The problem with your code is that you are applying a click event to the input and also to the div enclosing the button, but not to the actual button.

if you change your fiddle to this

<form id="test_form">
  <input type="file"id="test">
      <div id="test1"><button onclick="alert('click');">Upload</button></div>
</form>

and

$("#test1 button").trigger('click');

then the click trigger will be applied to the button. Alternatively give your button an ID and fo

$("#buttonid").trigger('click');

Solution 5:

You can do it somthing like as :

<button id="upld_btn">Upload</button>

$(document).ready(function () {
   $('#upld_btn').trigger('click');
});
