有清单。我需要找到Item 3元素，然后单击此元素中的“ 2”按钮。我该怎么办？
的HTML：
<body>
<div class="list>
<div class="item">
<div>
<p> Item 1 </p>
</div>
<button class='btn'> 1 </button>
<button class='btn'> 2 </button>
</div>
<div class="item">
<div>
<p> Item 2 </p>
</div>
<button class='btn'> 1 </button>
<button class='btn'> 2 </button>
</div>
<div class="item">
<div>
<p> Item 3 </p>
</div>
<button class='btn'> 1 </button>
<button class='btn'> 2 </button>
</div>
<div class="item">
<div>
<p> Item 4 </p>
</div>
<button class='btn'> 1 </button>
<button class='btn'> 2 </button>
</div>
</div>
</body>
js：
let findButtons = await
driver.findElements(By.className('item'));
let buttons = findButtons.map(elem => elem.getText());
const allButtons = await Promise.all(buttons);
// *** Find button ***
let tButton;
for (let i = 0; i < findButtons.length; i++) {
if (allButtons[i] == `Item 3`) { // compare all elements. Find `Item 3` element
tButton = await findButtons[i];
console.log(tButton.children); // need to display list of the children elements,
but it is displayed - underfined
tButton.click(); // click on the element is available
// but I need to click on the '2' button in the `Item 3` element
}
}
最佳答案
您可以使用xpath获得元素：
driver.findElement(By.xpath("//div[@class='item' and contains(.,'Item 2')]//button[normalize-space(.)='2']")).click();
关于javascript - 我很难从 promise 中派生 child ，我们在Stack Overflow上找到一个类似的问题：https://stackoverflow.com/questions/58929681/
