Sorted by: Reset to default. Highest score default Trending recent votes count more Date modified newest first Date created oldest first. I have a React component called FileDownload. All this component does is render a hidden form and then, inside componentDidMount , immediately submit the form and call it's onDownloadComplete prop.

one for each item in a table. Widget has corresponding action and store files. Widget imports FileDownload. Widget has two methods related to the download: handleDownload and handleDownloadComplete. Widget store has a property called downloadPath. It's set to null by default. When it's value is set to null , there is no file download in progress and the Widget component does not render the FileDownload component. The downloadFile action does NOT make an Ajax request. The store saves the downloadPath and emits a change event. Since there is now a downloadPath , Widget will render FileDownload passing in the necessary props including downloadPath as well as the handleDownloadComplete method as the value for onDownloadComplete.

However, this time downloadPath is set to null. The store saves the downloadPath as null and emits a change event. Since there is no longer a downloadPath the FileDownload component is not rendered in Widget and the world is a happy place. js - partial code only import FileDownload from '. toJS ; } handleDownload data { widgetActions. downloadFile data ; } handleDownloadComplete { widgetActions. dispatch { actionType: actionTypes. actionType { case actionTypes. merge { downloadPath: action. downloadPath, isLoading:!! downloadPath } ; this. emitChange ; break; FileDownload. keys queryParams. isRequired, method: PropTypes. string, onDownloadComplete: PropTypes. isRequired, queryParams: PropTypes. findDOMNode this. submit ; this.

nate Can header info be packaged with this form submission? charlie This is a standard HTML form submit. You can use the enctype attribute to specify three different values of the Content-Type HTTP header, but that's all. The Sending form data page on MDN might be helpful. Take a look at the section titled A special case: sending files. We have a use case where we first send an Ajax request to generate a download file, then we download. If you can use that option, you'll have more control over the headers in your Ajax request. This example is very helpful, but it still isn't clear to me how this implementation knows about whether or not the file has been downloaded. I see that the "onDownloadComplete" is called synchronously after submit, are you just making the assumption that there aren't any errors and that the server receives the request? Himmel Yes, sadly, this work around does not provide a way to confirm the file download was successful.

One possible solution could be to send an Ajax request prior to the download in Widget. js to confirm the server responds to a GET request to the download file path. Then, if successful, trigger the download. You still aren't confirming the download is successful, but if the file doesn't exist or there's some kind of network error at that time, you could handle the error. You might also want to look into putting the form in an iframe and read the iframe's content using the onload event. This is causing me to redirect.

When building a React application, sometimes you need to allow the user to download a file. For instance, if they purchase a ticket, they might want to download them in PDF.

Instead, you should create an endpoint that will return the response headers to trigger the download of a file.
