Dynamically create file input element

Issue

I want to customize the file input button, so I use this code to create an file input element

function inputBtn(){
    var input=document.createElement('input');
    input.type="file";
    setTimeout(function(){
        $(input).click();
    },200);
}

<button id="ifile" onclick="inputBtn()">create</button>

However, when I click create, it shows nothing.

Solution

You're creating the new DOM element, but you're not attaching it to the DOM. You need something like:

document.getElementById('target_div').appendChild(input);

You can see how this works in a poorly done JSFiddle here: http://jsfiddle.net/JQHPV/2/
