node.js - How to check multiple conditions to be true or false using protractor ,so that it helps in validating input before click -

here code want check value of inputs nick_name , room_name before clicking button(createroom_btn).but not getting how check multiple conditions in single if statement using protractor.

var nick_name = element(by.model('user.vcard.nickname')); var room_name = element(by.model('roomname')); var createroom_btn = element(by.tagname('button')); describe('protractor demo app', function () {     it('should click on create room button', function () {         condition = function () {             return [                 nick_name.getattribute('value').then(function (value) {                     return value.length > 0                 }),                 room_name.getattribute('value').then(function (value) {                     return value.length > 0                 })             ];         };         browser.wait(condition, 8000, "text still not present").then(function (resp) {         });         //button click                  browser.actions().mousemove(createroom_btn).click();     }); }); 

you should use 'and' expectedcondition - http://www.protractortest.org/#/api?view=protractorexpectedconditions.prototype.and - combine conditions. if have value waiting use texttobepresentinelementvalue expectedcondition - http://www.protractortest.org/#/api?view=protractorexpectedconditions.prototype.texttobepresentinelementvalue.

else check if value entered, can write custom condition check length.

var valuepresentnick = function() {   return nick_name.getattribute('value').then(function(txt) {     return txt.length > 0;   }); }; 

create similar room name - valuepresentroom

var condition = ec.and(valuepresentnick , valuepresentroom); browser.wait(condition, 5000);
