ES6 Tutorialpromise executes successfully and reject is the function that should be called when the promise encounters an error. let p =new Promise(function(resolve,reject){ let workDone=true; // some function passed resolve('success promise completed') } else{ reject('ERROR , work could not be completed') } }) Example The example given below shows function add_positivenos_async(n1, n2) { let p = new Promise(function (resolve, reject) { if (n1 >= 0 && n2 >= 0) { //do some complex time consuming0 码力 | 435 页 | 4.00 MB | 1 年前3
BabelJS Tutorialone argument, which is a callback function. The callback function has two arguments - resolve and reject; BabelJS 37 both these are internal functions. The asynchronous code which called; otherwise, the reject function is called with the error details. The following line of code shows a promise structure call: var _promise = new Promise (function(resolve, reject) { var success success = true; if (success) { resolve("success"); } else { reject("failure"); } }); _promise.then(function(value){ //once function resolve gets called it comes over here0 码力 | 173 页 | 2.70 MB | 1 年前3
ThinkJS 2.2 Documentationif(err){ deferred.reject(err); }else{ deferred.resolve(body); } }); } To convert it to promise style, you should create an deferred object to resolve or reject in callback function think.prevent for preventing the subsequent logic to execute. This method returns a specific type of Reject Promise. think.middleware('parse_xml', async http => { let payload = await http.getPayload(); process.nextTick(function(){ if(xxx){ deferred.resolve(data); }else{ deferred.reject(err); } }) return deferred.promise; } The way using Deferred is much cleaner than the0 码力 | 156 页 | 2.62 MB | 1 年前3
SQLite Development with Zumerothe Paul and John example, in version 3 of the database, "foo" would have the value 13. • action_reject The entire incoming package is rejected, causing the sync operation to fail. In the Paul and John Use of action_reject will mean that the mobile device wasted precious network bandwidth to upload a package which was discarded. There are no conflict situations for which action_reject is the default sync, a 'situation_mod_after_mod' conflict will occur. Assuming the rules do not not specify 'action_reject' as the action, version 3 of the database will be constructed in one of the three ways, depending0 码力 | 57 页 | 199.89 KB | 1 年前3
