Question

我正在尝试编写一个返回数组中完整网格内容的函数。我们的ng-grid可以无限滚动行，也可以滚动列。

我找到了在这里滚动的答案Protractor: Scrolling a table and testing for infinite scroll

但我希望完全滚动网格并获取数据，这样我就可以在将滤镜应用到网格时验证数据。

非常感谢任何帮助，谢谢

我能够滚动网格并以下列方式从所有行获取数据。我从Protractor: Scrolling a table and testing for infinite scroll获得了scrollDown代码（感谢@alecxe）

for循环中几乎没有硬编码。我应该找到一种方法来知道我应该滚动多少次表。最后的结果还有一些副本需要清理它。

＆＃13;

  
    scrollDown() {
    return browser.executeScript("return arguments[0].offsetTop;", this.lastRow.getWebElement()).then((offset) => {
      browser.executeScript("arguments[0].scrollTop = arguments[1];", element(by.className("ag-body-viewport")).getWebElement(), offset);
    });
  }

  getRows() {
    return this.pinnedRows.getText();
  }

  getTotalRows() {
    const defer = Promise.defer();
    let allRows = [];

    for (let i = 0; i < 3; i++) {
      this.getRows().then((rows) => {
        allRows = allRows.concat(rows);
        this.scrollDown();
        this.waitToLoad();
        if (i === 2) {
          defer.resolve(allRows);
        }
      });
    }
    return defer.promise;
  }

  waitToLoad() {
    waitFor.elementToBeVisible(this.pinnedRows.get(15));
    browser.waitForAngular();
  }

＆＃13;

在规范中：

＆＃13;

  getTotalRows().then((data) => {
      log.info(`TOTAL ROWS: ${data}`);
      log.info(`TOTAL NUMBER OF ROWS : ${data.length}`);
      expect(data.length).toBeGreaterThan(50);
    });

＆＃13;

您需要从dom中找到最后一行并使用scrollintoview javascript函数。请找下面的例子。

var last_row=element.all(by.css(".ag-row")).last() //this will give you the last row from the grid
browser.executeScript("arguments[0].scrollIntoView();",last_row.getWebElement());

这将滚动整个网格。现在您可以通过

获取行中的所有文本

element.all(by.css(".ag-row")).getText().then(function(RowValueArray) { 
         //do whatever you want to do with the values.
})

希望它可以帮到你！
