在我们的应用程序中，我们有两个地方是wie ha自由文本搜索字段。下面是显示扩展搜索选项区域的按钮。这可以在Chrome上使用Selenium Java作为测试工具，但在PhantomJS的一个地方。什么不起作用是通过单击按钮显示扩展选项。
按钮如下所示：
<a id="extendSearch" href="javascript:;"[ngClass]="setToggleExtendedSearchLinkClasses()" (click)="toggleExtendedSearch()">
{{extendSearch | translation}}
<span class="JM_icon-check" [attr.data-check]="isFilterSelected() ? true : false"></span>
</a>
功能＆＃34; toggleExtendedSearch（）＆＃34;看起来像这样：
toggleExtendedSearch() {
console.log("document-search component: toggleExtendedSearch is called");
if (this.extendedSearchOn) {
this.extendedSearchOn = false;
}
else {
this.extendedSearchOn = true;
}
console.log("document-search component.toggleExtendedSearch:" + this.extendedSearchOn);
}
使用此Angular标记显示扩展搜索选项的区域：
<app-document-search-extended #extendedSearch [hidden]="!extendedSearchOn" (onFilterReset)="resetAllFilters($event)"
(onSubmitFilter)="toggleExtendedSearch()"></app-document-search-extended>
测试用例的代码如下所示：
SyncingWebDriverEventListener.whenStable(driver, extendSearch);
extendSearch.click();
SyncingWebDriverEventListener.whenStable(driver, extendSearch);
Select dropdownFoerderbereiche = new Select(foerderbereiche);
List<WebElement> optionsFoerderbereiche = dropdownFoerderbereiche.getOptions();
LogEntries logs = driver.manage().logs().get("browser");
System.out.println();
System.out.println();
System.out.println("==================== Start Browser Console Log ====================");
System.out.println();
for(LogEntry entry : logs) {
System.out.println(entry.toString());
}
System.out.println();
System.out.println("==================== End Browser Console Log ====================");
System.out.println();
System.out.println();
dropdownFoerderbereiche.selectByIndex(1);
＆＃34; extendedSearch＆＃34;是有问题的按钮和＆＃34; click89＆＃34;工作没有错误，至少根据Selenium，但它实际上并没有做我应该做的事情。 ＆＃34; dropdownFoerderbereiche.selectByIndex（1）;＆＃34;然后休息，因为＆＃34; dropdownFoerderbereiche＆＃34;在上面的点击应该显示的区域内，但不是。因此，Selenium会因为拒绝操纵不可见的元素而中断。
＆＃34; SyncingWebDriverEventListener.whenStable（driver，extendSearch）;＆＃34;实际上会调用＆＃34; whenStable（）＆＃34;在以下JS代码中：
(function() {
"use strict";
window.webtest = new function() {
this.markers = {};
this.whenStable = function(callback, element) {
try {
angular.getTestability(element || document.body).whenStable(callback);
} catch (e) {
callback();
}
};
function _sendTimings(callback, angularRequestEnd) {
try {
var timing = {
url : location.href,
navigation : performance.timing,
angular : {
requestEnd : angularRequestEnd
},
resource : performance.getEntries ? performance.getEntries() : null
};
var json = JSON.stringify(timing);
performance.clearResourceTimings && performance.clearResourceTimings();
callback(json);
} catch(e) {
callback(null);
}
}
this.loadMetrics = function(callback) {
try {
angular.getTestability(document.body).whenStable(function() {
_sendTimings(callback, performance.now());
});
} catch(e) {
_sendTimings(callback);
}
};
};
console.log("Webtest js code active.");
})();
错误如下所示：

我们还尝试了几秒到几秒钟的简单等待（我认为从5到10或甚至30或60）并且还使用了ngWebDriver（https://github.com/paul-hammant/ngWebDriver）来等待，但这些都没有奏效。它工作的其他代码位置使用以下代码等待它在那里工作，但不适用于此位置。它只在＆＃34; click（）＆＃34;。
之后才使用它public void waitUntilElementIsPresent(WebElement webElement) {
ExpectedCondition clickableCondition = ExpectedConditions.elementToBeClickable(webElement);
this.waitForCondition(clickableCondition);
}
工作部分的代码是相同的。
在PhantomJS中调用该函数并且＆＃34; extendedSearchOn＆＃34;设置为true（我记录了，如您所见）。但尽管如此，该地区仍然隐藏着。因为它在其他地方工作，可能会有副作用，但我绝对不能说出原因。所以也许你可以告诉我你需要哪些额外的信息来阐明它，我很乐意提供它。
