如何等待頁面重新加載硒？

Question

考慮下面的代碼：

$this->visit('/'); 
$text = $this->byCssSelector('.some-element')->text(); 
$this->byCssSelector('.some-link')->click(); 
# how do I wait for a new page to be loaded here? 
$this->assertEquals($text, $this->byCssSelector('.some-element')->text()); 

Answer 1

從我可以在網絡上看到，執行JavaScript是要避免如果可能的話，所以我想出了非JavaScript的解決方案：

$this->visit('/'); 
$text = $this->byCssSelector('.some-element')->text(); 
$this->waitForPageReload(function() { 
    $this->byCssSelector('.some-link')->click(); 
}, 5000); 
$this->assertEquals($text, $this->byCssSelector('.some-element')->text()); 

function waitForPageReload($navigate_f, $timeout) { 
    $id = $this->byCssSelector('html')->getId(); 
    call_user_func($navigate_f); 
    $this->waitUntil(function() use ($id) { 
     $html = $this->byCssSelector('html'); 
     if ($html->getId() != $id) 
      return TRUE; 
    }, $timeout); 
}

您可以設置（通過JS調用）window.is_old_page = true，並檢查，直到這將是undefined
