How to prevent form resubmission on page refresh or back button in express js ? On refresh I want the same page to be reloaded and on back button the previous state of the page .
Is there a particular reason you want to keep the data on the form the same upon refresh?
If you want it to be saved upon refresh you need to save the data the user inputs somewhere.
Either locally in local storage or on the server.
If you choose local storage: On every refresh you check local storage to see if data is already there and if so you populate the form with that data.
If you choose to store the un-submitted data on the server you should be maintaining a session with the server. You can use a cookie here and node has a few good options/ways to do this.
Storing what page the user is on can also be stored in either location.
If you have the option to choose either local or remote - I'd go with local storage.

I need to get some data from a form as POST request and save that data so i can use it on another page.
I am successful at retrieving the data form the form as JSON, but since i am not using any database, i am not able to see the data that i retrieved from the form when i redirect for the next page..
I am new at using jade, nodejs and express. I'd like a opinion on how to retrieve the data that i've sent via post method.
If i use render, it loads the page with all the correct info, but if i reload or change to another page, the data will simple disappear.
You can use Redux Persist (state management tool) or local storage to save data. Both of these will save your data in a way that it can be retrieved when you navigate to the next page or even if you reload your page.
I am using jdeveloper 12c to build fusion web app with oracle 12c database.
My project is running fine in browser and also can be accessible on other system's browser via static IP.
When someone is accessing application in browser and enter some data in table, it saves in database but it doesn't reflects on my browser even after refreshing page until unless i rebuild my project.
How can i get data without rebuilding my project (I want to fetch all updated data through page refresh).
I don't want to create a method for this.
Browser page refresh doesn't call data querying. You need to call Execute on needed iterators. For instance you can start a taskflow with Execute method before showing user interface.
I am not sure but, use Execute of that particular VO after commiting the data.Before using Execute in java code you have to add Execute in page deinition or go to that particular table in page. use binding property under property inspector. create the binding as given #{backingBeanScope.popupBean.refresh} and call it in java as like this to refresh the data while saving in DB 'AdfFacesContext.getCurrentInstance().addPartialTarget(refresh);'
Only you need to add EXECUTE button from that specific table (of which you want to refresh data) operation in data control tab, and you can label it as REFRESH button.
I have an electron app that acts as a tool to speed up game development. When a user opens the app they can begin importing assets and setting custom properties. I store these properties in nedb. The way I have my application set up, every page change the properties from nedb are fetched and are immediately reflected on the page. I need to save these changes in a file the app can load and it would be intuitive to use nedb since it loads database info from a file optionally out of the box. However in the instance a user opens my app and begins working without a file, I have no way to store these changes for later use. I have found no docs for exporting the database on the fly.
I was viewing this website which has an awesome customized search options panel. I was wondering how can we remember the state of checkboxes and textfields when the query returns the results and HTML page renders. Take this page for example, it saves the user's selected options when the page refreshes. I want to implement this feature in Node, Mongo and Express.
There are two ways you could do this. If you want to persist the options long term, when the user selects something, you'd send a POST or PUT request to the server and have the server save the settings in Mongo. The second option (which I think is a better choice here) is to just use local storage on the client. See this documentation for how to use local storage.
With local storage, everything is client-side, so you don't have to worry about the latency and complication of dealing with the server. The user will have their options saved on that computer until they go into their browser settings and delete it.
Edit: I think what you're looking for is session storage. This is similar to local storage but it gets reset when the browser window closes or the session expires.
I've started using hood.ie to make a web app.
I wanted to ask is there a convenient way to refresh pages whenever data in the couch db changes?
Thanks.
If you have a function that renders your page, like render, you can do this
hoodie.store.on("change", render)
The "change" event will trigger every time something changes in your data, be it because you called on of the hoodie.store APIs, or because of a changed synced from remote
