javascript - 尝试使用 Protractor 选择消息时索引带外

Question

我正在尝试使用此 HTML 代码选择一条警告消息“未分配的金额..”

我尝试使用这行代码来选择它

  var warning=element.all(by.xpath('.//span[.="Unassigned Amount = 20.00"]')).filter(function (elm) {
    return elm.isDisplayed().then(function (isDisplayed) {
        return isDisplayed;
    });
});

但是我从 Protractor 得到了这个错误:

Message:
    Failed: Index out of bound. Trying to access element at index: 0, but there are only 0 elements that match locator By(xpath, .//span[.="Unassigned Amount = 20.00"]

Answer 1

我怀疑 XPath 表达式内部的严格相等性检查是问题所在，因为文本周围有额外的空格。试试 contains() :

.//span[contains(., "Unassigned Amount = 20.00")]

你也可以用by.cssContainingText locator来解决。 :

element.all(by.cssContainingText("span[data-for=APIInvoiceAmount]", "Unassigned Amount = 20.00"))
