given a path of a file like:
C:\file.jpg
how can i get the size of the file in javascript?
To check file size using HTML5 and JavaScript, we can use a file input and check the file's size after selecting the file. document. getElementById("fileInput"). onchange = () => { const fileSize = document.
To get the size of a file in Node. js, you can use the stat() method provided by the built-in fs module. This method works asynchronously and lists the statistics of a file at the given path. The size of the file is returned in bytes.
If it's not a local application powered by JavaScript with full access permissions, you can't get the size of any file just from the path name. Web pages running javascript do not have access to the local filesystem for security reasons.
You can use a graceful degrading file uploader like SWFUpload if you want to show a progress bar. HTML5 also has the File API, but that is not widely supported just yet. If a user selects the file for an input[type=file]
element, you can get details about the file from the files
collection:
alert(myInp.files[0].size);
