javascript - Put a promise in a pending state -

i want defer execution of promise, until user input provided.

i want post, wait until has happened, this:

while (true) {   promiseforuserinput = pending;   strinput = rl.question("provide input"); //waits user input   promiseforuserinput = resolved;   var resultofuserschoice = promiseforuserinput.then(function(input) {     return loadfromserver(input)   }).then(function(serverresponse) {     console.log(serverresponse)   }); } 

is possible? need read on factory functions?

that have work this:

new promise(function (resolve) {     document.getelementbyid('my-input').addeventlistener('keyup', function (e) {         if (/* input value enough */) {             resolve(e.currenttarget.value);         }     }); }) 

to input (i'm assuming browser context here), have bind event listener input element , read input element upon decided event. inside promise, , resolve promise you're happy input value.

you can .then promise:

thepromise.then(function (input) {     alert(input); }); 

the input data resolved value.
