Use async function in preUpload

geonovation

Hello,

I want to change the upload file with an async function. I tried this code below but this isn't working. Is there a solution for this problem that I have?

datatableEditor.on( 'preUpload', function ( e, fieldName, file, ajaxData ) {

    loadImage(file, { maxWidth: 300 }).then(function (image) {
        ajaxData.set('upload', image);
    })
});

datatableEditor.on( 'preUpload', async function ( e, fieldName, file, ajaxData ) {

    // check image and resize image
    const image = await loadImage(file, {maxWidth: 300});

    ajaxData.set('upload', image);
});

Hi,

I'm afraid there is no provision of an async function in the preUpload event. That said, preUpload is only intended for use to return a boolean value to say the file should be uploaded to the server or not.

It sounds like in this case you could do:

datatableEditor.on( 'preUpload', function ( e, fieldName, file, ajaxData ) {
    loadImage(file, { maxWidth: 300 }).then(function (image) {
        ajaxData.set('upload', image);
    });

    return false;
});

I don't see any reason why that won't work (assuming loadImage gives the promise a string?).
