Question

我正在使用Selenuim和Javascript来测试我的测试。 DOM有4个元素：

<input class="hidden-element xyz">，<input class="hidden-element xyz">，<input class="xyz">和<input class="xyz">

我希望找到仅包含xyz类的元素，而不是包含hidden-element和xyz的元素。当我说：

if (driver.findElements({css: 'section[title="custom"] > input.xyz'})) {
  driver.findElements({css: 'section[title="custom"] > input.xyz'}).then(function(inputs) {
    for (i = 0; i < inputs.length; i++) {
      inputs[i].sendKeys('Input Text');
    }
  });
}

它将拉出所有4个元素，尝试填充隐藏元素，并打破测试。我试过了：

if (driver.findElements({css: 'section[title="custom"] > input.xyz'}) && !driver.findElements({css: 'section[title="custom"] > input.hidden-element'})) {
  driver.findElements({css: 'section[title="custom"] > input.xyz'}).then(function(inputs) {
    for (i = 0; i < inputs.length; i++) {
      inputs[i].sendKeys('Input Text');
    }
  });
}

但这也不起作用。我也一直在玩这种不同的变化，但无济于事。这似乎很简单，但我很难在解决方案上磨练。想法？

Answer 1

你的选择器应该是：

.xyz:not(.hidden-elem)

这是因为A and not(A and B)有效地倾注到A and not B

编辑：好像你已经找到了逻辑

Answer 2

我建议，如果可能有多个其他类名要过滤掉：

function uniquelyClassed (arr, cName) {
  if (arr instanceof Array) {
  return arr.filter(function (n) {
    return n.classList.length === 1 && n.classList.contains(cName);
  });
  }
}

var elements = document.querySelectorAll('input'),
    elementsArray = Array.prototype.slice.call(elements, 0),
    uniquelyXYZ = uniquelyClassed(elementsArray, 'xyz');

uniquelyXYZ.forEach(function (el) {
  el.classList.add('found');
});

＆＃13;

input {
  margin: 0 0 0.5em 0;
  display: block;
}
.found {
  border-color: limegreen;
}

＆＃13;

<input class="hidden-element xyz">
<input class="hidden-element xyz">
<input class="xyz">
<input class="xyz">
