Why I cannot hide the loading bar (spinner)?
Symptom:
In v17.3 of the Dynamic Web TWAIN SDK, you may find the spinner is unable to hide with the method mentioned in this article, it will continue to spin or will never stop.
Cause:
The event Dynamsoft.OnWebTwainPreExecuteCallback is not registered in the dynamsoft.webtwain.install.js file in v17.3 so that the Dynamsoft.DWT.OnWebTwainPreExecute() will never be called.
Workaround:
Step 1) In the dynamsoft.webtwain.install.js file, add the event behind the function OnWebTwainPostExecuteCallback.
Dynamsoft.OnWebTwainPreExecuteCallback = function(){
console.log("OnWebTwainPreExecuteCallback")
}
Step 2) Follow the step in this article.
Note: If Dynamsoft.DWT.AutoLoad in your code is set to false, please contact us.
