jquery - Trigger file upload via Javascript only -

-

I want to write a browser add-on that automatically uploads the file to the page. So it will be done in pure javascript.

It is that I have / know:

  1. input # some id

  2. The file name and location in the computer

I am trying to "hardcode" in "codecode"

Code> inputElement.click () As inputElement The input querySelector .

  • Use initMouseEvent but I got the error Uncustom Type error: Properties 'dispatchEvent' can not be read

    < / Li>

    So my questions are:

    1. How to trigger the click input of the file upload element?

    2. Improved: How to Process Upload Completely? Pass the file name + location to basically upload (like the user clicks the OK to open the file from the dialog)

    UPDATE 1: / Strong>

    I was reading this probably a file uploaded from the file system is not possible. How about these options:

    1. We can get a file from the URL (HTTC)

    2. The file is just image and Javascript is in Memory (Base64)

    Any of the above should be fixed, if it can be automatically uploaded and bypasses the dialog box and the file is localized The file can search through the system. I'm wondering if the image DOM or Canvas can be pulled?

    • People commented, can not do this. For security reasons, you have no access to filling up a file input until programmatic Think about it, some friends can add a simple script to steal files from your computer and you will not even know!

    As far as I know, can not be done.

So I have to know whether the property has been allocated or set to zero. I'm aware of INotifyPropertyChanged , but in my case I'm not sure that since this change I have changed my car properties car do not want to monitor the property. Any idea how to accomplish this? In advance thank you If you have created a true asset in your class then You should be a great and setter, you can add the code directly to the form property in order to take action on the basis of "form": Public partial category Form 1: form {public form 1 () {InitializeComponent (); } // define car square public class car {public string name = string. Empty; } // private car to keep the value of the current car private variable _car = null; // Property of public form which you can ru...
