dropzone.js给出错误“无效的dropzone元素";在没有Dropzone的页面上 [英] dropzone.js is giving error "Invalid dropzone element" on page without a dropzone
问题描述
我正在使用dropzone js,在需要dropzone的页面上效果很好.在任何其他页面上,它都会给我一个"Invalid dropzone element"
错误消息,并导致其他JavaScript出现问题.
I'm using dropzone js and it's working great on pages that I require a dropzone. On any other page though it's giving me a "Invalid dropzone element"
error message and causing issues with my other javascript.
我有一个自定义JS文件(该文件在dropzone.js文件之后立即加载),并且在文件的顶部,我有以下代码行:
I have a custom JS file (which loads immediately after the dropzone.js file) and at the very top of the file I have the following line of code:
Dropzone.autoDiscover = false;
这应该阻止它查看我没有以编程方式启用它的任何页面.该错误只会在存在有效拖放区的页面上消失.
This should stop it from looking at any page where I'm not enabling it programatically. The error only goes away on pages where there is a valid dropzone.
我还在dropzone.js的第1470行上设置了以下代码,尝试也在其中启用它:
I also set the following code on line 1470 on dropzone.js to try and enable it there too:
Dropzone.autoDiscover = false;
如何摆脱这个错误?
推荐答案
使用纯JS,您可以尝试以下方法:
With pure JS you can try this:
if (document.getElementById('DropzoneElementId')) {
var myDropzone = new Dropzone("div#DropzoneElementId", { url: "/file/post"});
// other code here
}
或者如果您使用jQuery:
or if you use jQuery:
if ($('#DropzoneElementId').length) {
$("div#DropzoneElementId").dropzone({ url: "/file/post" });
// other code here
}
