如何自定义 Dropzone js？

Question

如何自定义 Dropzone js？我搜索了几个小时，但只是循环往复。我正在尝试摆脱这个...

对于这样的事情...

我不需要背景或任何花哨的样式，并且该功能已经可以使用。我只是主要需要文件就像它们在红框中一样。但我不知道从哪里开始。

这是我用来设置您在第一张图片中看到的样式的 main.js 和 css...

Dropzone.autoDiscover = false;

const myDropzone = new Dropzone("#my-dropzone", {
    url: "upload/",
    maxFiles: 2,
    maxFilesize: 20,
    acceptedFiles: '.csv, .xlsx',
    preview_image: false,
    inputLabelWithFiles: false,
    // autoProcessQueue: false,
    // uploadMultiple: True,
    // previewTemplate: '',
})

body {
    background-color: #f8f8f8;
}

.dz {
    border: dashed !important;
    border-color: #ccc !important;
    border-radius: 10px !important;
}

.dz:hover {
    background-color: aliceblue !important;
}

Answer 1

我这样做的方式，每次我下载一个文件我调用ajax函数，它首先添加css（显示：无），用于dropzone中的元素，然后调用php脚本。它负责显示保存到之前为空的 div 中的所有文件（div 位于 dropzone 下）。

Answer 2

你可以检查这个article

 new Dropzone(target, {
        ... 
        previewTemplate: previewTemplate,
        previewsContainer: "#previews",

另外，在documentation

Answer 3

好的，所以我想我需要编辑 dropzone 的 html，但我找不到。但是，我意识到我只需要 css。在尝试了不同的事情之后，这就是现在的样子...... 这是更新后的 style.css...

body {
    background-color: #f8f8f8;
}

.dz {
    margin-top: 180px;
    border: dashed !important;
    border-color: #ccc !important;
    border-radius: 10px !important;

    /* REQUIRED. This will prevent the dropzone area from getting bigger.*/
    max-height: 150px !important;
}


/* Here are the other styles for Dropzone. 
These will give it the same look as in the
picture. Which I think is better for non image files.*/

/* Manually place the uploaded files.*/
.dropzone .dz-preview {
    top: 200px !important;
    margin: 0px !important;
    min-height: 0px !important;
}

/* Manually create the shape of the bubble.*/
.dz-image {
    width: 1000px !important;
    height: 20px !important;
    /* Add this to create cool colors, if you want. */
    /* background: linear-gradient(to bottom, #28a745, #dc3545) !important; */
    position: relative;
}

/* Manually put the file size into the bubble. */
.dropzone .dz-preview .dz-details > .dz-size {
    position: absolute;
    top: 0px !important;
}

/* Manually put the file name into the bubble.*/
.dz-details > .dz-filename {
    position: absolute;
    top: 0px !important;
    left: 100px !important;
}

/* Put the details below the upload area and button. */
.dz-details {
    position: absolute;
    top: 305.5px;
}

/* Make the loading bar slim and cover 80% of the file bubble.*/
.dropzone .dz-preview .dz-progress {
    position: relative !important;
    height: 6px !important;
    left: 0px !important;
    width: 80% !important;
    margin-left: 97px !important;
    border-radius: 0px !important;
}

/* Haven't changed the checkbox that comes after the loading bar.*/

如果你下载了它，你也可以将这些实现到 dropzone.css 文件中。我已经做到了...

如果您想要相同的外观，只需复制所有内容并换出现有的 dropzone.css 文件。 无论如何，希望这可以帮助任何想要使用这种风格的 dropzone 的人。我认为这是任何非图像文件的想法。没有 html javascript 或其他任何东西。只是纯 CSS。
