javascript - why cordova dont save jspdf?

the code works only by starting it from the browser, while in the phone the button does not generate pdf ... I state that I've been using Cordova recently and maybe I can't set the plugins well .. any information, even trivial, can be useful. the cart table is generated by a javascript code that uses the dom on another hatml page, I think that something is almost certainly missing to make the app store the file on the device but I don't know what to insert .. also which plug in to refer to possibly .. Thanks in advance to everyone

You can not use JSPDF to save files on a mobile phones, at least to my knowledge. In my experience I would try looking at Cordova documentation online. For example: https://cordova.apache.org/docs/en/latest/reference/cordova-plugin-file/#write-to-a-file-

If you want to use File plugin make sure you install it first and go through documentation! https://cordova.apache.org/docs/en/latest/reference/cordova-plugin-file/index.html#installation

There also seems to be Cordova generator plugin, but i don't have any experience with it https://www.npmjs.com/package/cordova-pdf-generator

Either way, I would advise you to refactor your code without jspdf.
