ElementNotVisibleError：無法在量角器IE瀏覽器中點擊元素錯誤

Question

當我嘗試在IE_11瀏覽器中執行量角器腳本時，我遇到了以下錯誤。但是，在Chrome瀏覽器和Firefox瀏覽器中正常工作的腳本相同.Saying元素不可見。但當我通過暫停瀏覽器手動執行腳本時，各個元素都可見。

Answer 1

這聽起來像你有時間問題。您可以嘗試使用預期條件功能（http://www.protractortest.org/#/api?view=ExpectedConditions）。它甚至看起來像他們的例子適合你所需要的：

var EC = protractor.ExpectedConditions; 
var button = $('#xyz'); 
var isClickable = EC.elementToBeClickable(button); 

browser.get(URL); 
browser.wait(isClickable, 5000); //wait for an element to become clickable 
button.click();
