Element.getAttribute() 将 promisestatus 返回为待处理：protractor

Question

My Statement

var data = elmnt.getAttribute('row-id').then(function(value){
    rowid = value
    callback();
}); 
console.log('global var inside Rowid:'+ rowid);
console.log('global var inside data:'+ data);

My Output :

global var inside Rowid:null global var inside data:ManagedPromise::19682 {[[PromiseStatus]]: "pending"}

can someone please help

Ah, sorry, didn't notice the protractor tag.

So, if we have a promisified getAttribute , then that's how you consume promises:

elmnt.getAttribute('row-id').then(function(rowId) {
    console.log(rowId);
}); 

You need to do it inside the promise chain. console.log(somePromise) will only log a promise, not a value, and console.log(rowid) before the promise is resolved will produce null / undefined .
