我正在做一個WebApp,在那里人們將上傳2張圖像,我需要通過python代碼來傳遞這些圖像。因此,我只想讓他們在上傳2張圖像后發(fā)送。但我無法將其推斷為我的情況:<!DOCTYPE html><html><head> <link rel="stylesheet" type="text/css" href="https://unpkg.com/file-upload-with-preview@3.4.3/dist/file-upload-with-preview.min.css"></head><body> <!-- Uploader --><div class="custom-file-container" data-upload-id="myImage"> <label>Upload your images <a href="javascript:void(0)" class="custom-file-container__image-clear" title="Clear Image">×</a></label> <label class="custom-file-container__custom-file" > <form id="upload-form" action="{{url_for('upload')}}" method="POST" enctype="multipart/form-data"> <input type="file" class="custom-file-container__custom-file__custom-file-input" accept="image/*" aria-label="Choose File" multiple> <input type="hidden" name="MAX_FILE_SIZE" value="10485760" /> <span class="custom-file-container__custom-file__custom-file-control"></span> </label> <div class="custom-file-container__image-preview"></div></div><input type="submit" name="send" disabled/></div><script src="https://unpkg.com/file-upload-with-preview@3.4.3/dist/file-upload-with-preview.min.js"></script><script> var upload = new FileUploadWithPreview('myImage', {showDeleteButtonOnImages: true, text: {chooseFile: 'Nom del fitxer', browse: 'Examina'}})</script><script src="https://code.jquery.com/jquery-1.9.1.min.js"></script><script>$(document).ready( function(){ $('input:file').change( function(){ if ($(this).val()) { $('input:submit').attr('disabled',false);; } } ); });</script></body></html>添加的最后一個腳本是第一個鏈接中給出的解決方案,它可以正常工作,但不是我想要的。文件上傳器代碼來自https://github.com/promosis/file-upload-with-preview,在這里我看到有一種稱為selectedFilesCount的方法可能有用。感謝您的時間,如果您在我的代碼中看到一些廢話,則感到抱歉,但是我是這些語言的新手...
如何在多個文件上傳器中啟用提交按鈕,直到出現(xiàn)條件?
