测试页面 – 使用单个元素的视图 – < li>它从服务器动态加载并由Angular绑定.
<div id="items">
<li>text</li>
<li>text2</li>
</div>
我试图通过测试
_driver.FindElements(By.TagName('li'))
问题在于,目前没有加载元素,而_driver.PageSource也不包含元素.
我如何等待装载物品？请不要建议Thread.Sleep()
/* C# Example
var pageLoadWait = new WebDriverWait(WebDriver,TimeSpan.FromSeconds(timeout));
pageLoadWait.Until<bool>(
(driver) =>
{
return (bool)JS.ExecuteScript(
@"*/
try {
if (document.readyState !== 'complete') {
return false; // Page not loaded yet
}
if (window.jQuery) {
if (window.jQuery.active) {
return false;
} else if (window.jQuery.ajax && window.jQuery.ajax.active) {
return false;
}
}
if (window.angular) {
if (!window.qa) {
// Used to track the render cycle finish after loading is complete
window.qa = {
doneRendering: false
};
}
// Get the angular injector for this app (change element if necessary)
var injector = window.angular.element('body').injector();
// Store providers to use for these checks
var $rootScope = injector.get('$rootScope');
var $http = injector.get('$http');
var $timeout = injector.get('$timeout');
// Check if digest
if ($rootScope.$$phase === '$apply' || $rootScope.$$phase === '$digest' || $http.pendingRequests.length !== 0) {
window.qa.doneRendering = false;
return false; // Angular digesting or loading data
}
if (!window.qa.doneRendering) {
// Set timeout to mark angular rendering as finished
$timeout(function() {
window.qa.doneRendering = true;
},0);
return false;
}
}
return true;
} catch (ex) {
return false;
}
/*");
});*/
