Customizing the appearance of a file input element can be challenging, particularly due to browser compatibility issues. However, there are effective techniques to achieve this:
1. HTML and CSS Customization:
<form action="#"> <div>
function getFile() { document.getElementById("upfile").click(); }
2. Automated Upload:
To automate the file upload process, add an onchange event to the file input element:
<form action="#"> <div>
function sub(obj) { var file = obj.value; var fileName = file.split("\"); document.getElementById("yourBtn").innerHTML = fileName[fileName.length - 1]; document.myForm.submit(); event.preventDefault(); }
3. Complete Example:
This comprehensive example includes all the necessary code for a fully functional custom file upload form with automated submission:
<html> <style> #yourBtn { position: relative; top: 150px; font-family: calibri; width: 150px; padding: 10px; border-radius: 5px; border: 1px dashed #BBB; text-align: center; background-color: #DDD; cursor: pointer; } </style> <script type="text/javascript"> function getFile() { document.getElementById("upfile").click(); } function sub(obj) { var file = obj.value; var fileName = file.split("\"); document.getElementById("yourBtn").innerHTML = fileName[fileName.length - 1]; document.myForm.submit(); event.preventDefault(); } </script> <body> <center> <form action="#" method="POST" enctype="multipart/form-data" name="myForm"> <div>
