使用DropZone.js逐个上传多个文件

Question

是否有可能使用dropzone.js逐个上传多个文件.以下是自定义dropzone配置脚本.

Dropzone.options.myDropzone = {
                autoProcessQueue: false,
                parallelUploads: 10,
                addRemoveLinks:true,
                init: function () {
                    var submitButton = document.querySelector("#submit-all");
                    myDropzone = this; // closure
                    submitButton.addEventListener("click", function () {
                        if(myDropzone.getQueuedFiles().length === 0)
                        {
                            alert("Please drop or select file to upload !!!");
                        }
                        else{
                           myDropzone.processQueue(); // Tell Dropzone to process all queued files.
                        } 
                    });
                },
                url: "upload.php"
            };

现在,它一次上传所有文件,这些文件都在进程队列中.由于上传文件大小会更大,所有文件都必须逐个上传.请帮忙缩短相同的内容.

我用它来逐个上传文件.希望这可以帮助.如果您想根据您的功能获取完整代码,请告诉我们.

当客户确认上传文件时,将调用startUpload().

    Dropzone.autoDiscover = false;
    var myDropzone = new Dropzone("#uploadModal", { 
        url: "upload.php", 
        paramName: "file_upload",
        maxFilesize: 1024, 
        maxFiles: 200,
        autoProcessQueue: false
    });

    function startUpload(){
        for (var i = 0; i < myDropzone.getAcceptedFiles().length; i++) {
            myDropzone.processFile(myDropzone.getAcceptedFiles()[i]);
        }
    }

    myDropzone.on('success', function(file, result) {
        try {
            result = JSON.parse(result)
            if (!result.error) {
                if(myDropzone.getQueuedFiles().length === 0 && myDropzone.getUploadingFiles().length === 0){
                    $("#uploadModal"). modal('hide');
                    myDropzone.removeAllFiles(true) ;
                }
            }
            //TODO - 
        } catch (e) {
            //TODO -
        }
    });

您需要将autoProcessQueue设置为true并将parallelUploads 设置为1。

将 autoProcessQueue 设置为 true 会告诉 dropzone 自动处理队列。将 parallelUploads 设置为 1 会告诉 dropzone 一次只从队列中上传一个文件。

Dropzone.options.myDropzone = {
            autoProcessQueue: true,
            parallelUploads: 1,
            addRemoveLinks:true,
            init: function () {
                var submitButton = document.querySelector("#submit-all");
                myDropzone = this; // closure
                submitButton.addEventListener("click", function () {
                    if(myDropzone.getQueuedFiles().length === 0)
                    {
                        alert("Please drop or select file to upload !!!");
                    }
                    else{
                       myDropzone.processQueue(); // Tell Dropzone to process all queued files.
                    } 
                });
            },
            url: "upload.php"
        };
