    text
    copied!<p>I have a file-input:</p> <pre><code>&lt;img id="uploadPreview"&gt; &lt;div id="changeImage"&gt;Change&lt;/div&gt; &lt;div id="customImage"&gt; &lt;input type="file" id="myfile" multiple style="display:none" onchange="PreviewImage();" /&gt; &lt;div class='upload blank' id="add-image"&gt;&lt;/div&gt; &lt;/div&gt; </code></pre> <p>The function is like below:</p> <pre><code>var oFReader = new FileReader(); oFReader.readAsDataURL(document.getElementById("myfile").files[0]); oFReader.onload = function (oFREvent) { document.getElementById("uploadPreview").src = oFREvent.target.result; }; function PreviewImage() { var oFReader = new FileReader(); oFReader.readAsDataURL(document.getElementById("myfile").files[0]); $("#uploadPreview").removeClass('hide'); //for manipulating something in the dom $('#changeImage').removeClass('hide'); //for manipulating something in the dom $("#customImage").addClass('hide'); //these are for manipulating something in the dom oFReader.onload = function (oFREvent) { document.getElementById("uploadPreview").src = oFREvent.target.result; }; }; </code></pre> <p>Everything works perfect. Now I have a Change button. I want if someone clicks on it then previous uploaded file-details to be gone. The function is something like below:</p> <pre><code>$('#changeImage').click(function(){ $('#uploadPreview').addClass('hide'); $('#customImage').removeClass('hide'); //here I want to remove/clear the details about the already previous uploaded file in the 'file-input'. So the same image can be shown if someone clicks it for once again. }); </code></pre> <p>Can you help on this?</p>
