How to upload a file in just one click
I have HTML page, which gives an option to upload a file to the server, there is a servlet action class at server side & it handles request and write the file. Here how it works
- Click to Browse the file and select the file
- click the submit button.
But I want to upload in just one click on any button, please take a look of my code and suggest how to do that using javascript/jQuery fn.
<html> <head>
<script type = "text/javascript">
function test() {
var uploadfile = document.getElementByID("upload_id");
uploadfile.click(); // here i can browse the file without clicking on file brows button
} </script> </h开发者_如何学JAVAead> <body>
<input type="button" id="just_one_click" value ="click me" onclick="test();" />
<form action="upload.do" method="post" enctype="multipart/form-data">
<input type="file" id="upload_id" name = "fileupload" />
<input type = "submit" value="upload" />
</form> </body> </html>
You can assign id (let's say 'myform') to your form and use document.getElementById('myform').submit(); instead of uploadfile.click();.
加载中,请稍侯......
