javascript - Protractor not able to identify the angularjs button using locator by.partialButtonText or by.buttontext -

angularjs object properties

<button class="btn ng-binding" data-ng-click="v.icle(vehidform.$valid);" tabindex="0"> continue </button> 

code used identify object

element(by.buttontext("continue"));  or   element(by.partialbuttontext("continue")); 

these guesses, here things try:

• use by.xpath locator:

  element(by.xpath("//button[contains(., 'continue')]")); 

• check data-ng-click value instead:

  $('button[data-ng-click="vm.addvehicle(vehicleaddform.$valid);‌"]'); $('button[data-ng-click*=addvehicle]'); 

• wait button to present:

  var elm = element(by.partialbuttontext("continue")); var ec = protractor.expectedconditions;  browser.wait(ec.presenceof(elm), 5000);  elm.click();
