问题 I'm using JSZip to add selected files into a single zip file. The issue is only the last selected file is being added to the zip (which is also corrupted), see code below: var zip = new JSZip(); var items = ''; var count = 0; var zipName = 'resources.zip'; $$('input[type=checkbox]').each(function(e){ if(e.checked){ if(e.id!='select-all'){ items = items + "'" + e.getAttribute('data-href') + "'|" + e.getAttribute('data-file') + ","; } } }); if(items!=''){ items = items.slice(0,-1) var tmp =

问题 I'm using the library JSZip to create .png files and add them to a zip archive to be downloaded. The problem comes when I add too many large files. I use a set of for loops to add the files to the zip then activate an automatic download. The issue seems to be that the download starts before the files have been updated so they end up with no data. for (var row = 0; row < 3; row++) { // Loop for rows for (var col = 0; col < 3; col++) { // Loop for cols if (cropSrc[row][col]) { // If data for

Or How to store base64 value in PHPMyAdmin. zip.generateAsync({type:"base64"}).then(function (content) { zip_file = "data:application/zip

File extracted from ZIP not recognized until re-save

问题 Q: Why would re-saving a file be different vs a direct extraction from a zip file? Particularly on Windows? Context I have an angular application that prepares a text file for import into a commercial machine. For user convenience, we provide the file inside a zip file so that the required folder structure can be provided to the user. They write this file to a USB drive and use that to import into the machine. Problem If the downloaded zip file is extracted directly onto the USB (to get the

问题 In my webpage, a user is supposed to upload a zipped file. Within the zipped file are 2 files: another zip file and a txt file. On my server, after receiving the zip, I want to unzip the zip file to extract the zip & txt file, then move those 2 files to a predefined folder. I have a piece of code that extracts the zip file, but the data doesn't seem correct. Firstly, it unzipped a zip and 2 txt file when there should only be 1 txt file. It created an additional 'undefined' txt file. Also, in

Is there a way to suggest this folder structure via the download dialog without having to use a zip file? We use a zip today, but Windows users are having problems with the extracts working on
