Async-Await or Promises with JavaScript functions [closed]












-12














I am building an application in Cordova using Firebase for the database.



I have been using promises to get information back from the database and it works great, but once I get that back I usually have a series of functions that I need to call to update everything.



For example,




  1. update local storage


  2. call variable from local storage


  3. reload page with updated storage information



I need to create/convert my JavaScript functions to be able to be called in succession.






javascript asynchronous promise async-await synchronous

  • Most likely your issues stem from updateCS() not returning a Promise (or even if it does, you're not using it)

    I don't get your explanation why you "cant use a .then on this or place it in the .then above". Please try it and show us that code, the approach should work.

What you are really asking is how to implement a function after a promise is done. If so, then making the function an Async function will do the trick.



For information on async-await check out Async/await.

  • Yeah, basically I have 8 functions that get called through out my app. Some of them need to be called in succession for the other ones to work. For example: update local storage variable needs to be done updating before i call that local storage variable to populate what is on the page. then once this is all done reload the page. I read that async stuff but without a more specific example it has always been hard for me to reverse engineer.

For other uses, see Quarantine (disambiguation). Signal flag "Lima" called the "Yellow Jack" which when flown in harbor means ship is under quarantine. A simple yellow flag (also called the "Yellow Jack") had historically been used to signal quarantine (it stands for Q among signal flags), but now indicates the opposite, as a signal of a ship free of disease that requests boarding and inspection. A quarantine is used to separate and restrict the movement of people; it is 'a restraint upon the activities or communication of persons or the transport of goods designed to prevent the spread of disease or pests', for a certain period of time. [1] This is often used in connection to disease and illness, such as those who may possibly have been exposed to a communicable disease. [2] The term is often erroneously used to mean medical isolation, which is "to separate ill persons who have a communicable disease from those who are healthy...
