环境:
导轨6.0.2 Ruby 2.5.3
我用纱安装了cropperjs, 然后我想使用cropper.js, 但是我得到了这个错误, 看来无法在fileUpload.js中导入cropbox模块 所以,我改变了路径,可惜我无法导入cropbox, 你想帮我吗?
app / javascript / packs / fileUpload.js:
import cropbox from 'cropbox' **#Here is problem **
uppy.on('upload-success',(file,response) => {
// retrieve uploaded file data
const uploadedFileData = response.body['data']
// set hidden field value to the uploaded file data so that it's submitted
// with the form as the attachment
hiddenInput.value = JSON.stringify(uploadedFileData)
cropbox(imagePreview,response.uploadURL,{
onCrop(detail) {
let fileData = JSON.parse(hiddenInput.value)
fileData['metadata']['crop'] = detail
hiddenInput.value = JSON.stringify(fileData)
}
})
})
之前:
import cropbox from 'cropbox'
之后1:
import cropbox from 'javascript/packs/cropbox'
之后2:
import cropbox from 'app/javascript/packs/cropbox'
