sessionStorage over localStorage in PhoneGap

问题:

I am currently developing a PhoneGap application and am using sessionStorage rather than localStorage because we are facing some problems with localStorage.

Are there any downsides to using sessionStorage over localStorage?

回答1:

sessionStorage gets erased every time you close the application. Other than that there is no difference.

Here is the usage example:

var keyName = window.sessionStorage.key(0); //Get key name
window.sessionStorage.setItem("key", "value"); //Set item
var value = window.sessionStorage.getItem("key");// Get item
window.sessionStorage.removeItem("key"); //Remove Item 
window.sessionStorage.clear();//Clear storage
