I use Tinymce, I have two dots at the beginning of the url when I insert an image file, how can this be removed.Beacause

The project has been seamlessly integrated into the target file,

I register the HTML result in the database

I am undoing the record but there is a double dot in the image source

I need to remove double

how do I make that change img src="../Content/Images/Upload" > img src="/Content/Images/Upload"

  tinymce.init({

Solution

TinyMCE has a variety of configuration options to deal with URLs and how they are processed. Take a look at the following:

https://www.tinymce.com/docs/configure/url-handling/

...and specifically the following on that page:

The last of those (urlconverter_callback) allows you to implement your own logic if TinyMCE's built in options don't solve your issue.
