如何使用量角器从表格中获取一行及其列 [英] How to get a row and its column from a table with Protractor

问题描述

<表格><tr><td>row1Col1</td><td>row1Col2</td><td>row1Col3</td></tr><tr><td>row2Col1</td><td>row3Col2</td><td>row4Col3</td></tr><tr><td>row3Col1</td><td>row3Col2</td><td>row3Col3</td></tr></tbody>
var grid = element.all(by.css('.k-grid-content tr'));//这将返回row1,row2,row3

但我无法使用下面的代码来获取每一行及其列.

grid.each.each(function(row){var rowElems = row.findElements(by.tagName('td'));期望(rowElems.get(0).getText()).toMatch('/Col1/');});

显示以下错误消息.信息:类型错误:对象 [object Object] 没有方法 'findElements'

解决方案

你的 grid 设置没问题，但为了捷径:

var grid = $$('.k-grid-content tr');

关于您的问题，请避免使用 findElements 并使用链接 element 或在这种情况下使用 all 量角器功能.但我会再次使用 $$ 快捷方式:

grid.each(function(row) {var rowElems = row.$$('td');期望(rowElems.count()).toBe(3);期望(rowElems.get(0).getText()).toMatch('/Col1$/');});

<div class="k-grid-content">
    <table>
        <tbody>
            <tr>
                <td>row1Col1</td>
                <td>row1Col2</td>
                <td>row1Col3</td>
            </tr>

            <tr>
                <td>row2Col1</td>
                <td>row3Col2</td>
                <td>row4Col3</td>
            </tr>

            <tr>
                <td>row3Col1</td>
                <td>row3Col2</td>
                <td>row3Col3</td>
            </tr>

        </tbody>
    </table>
</div>


var grid = element.all(by.css('.k-grid-content tr')); //this will return row1,row2,row3

but I am unable to use code below to get each row and its column.

grid.each.each(function(row){
    var rowElems = row.findElements(by.tagName('td'));
    expect(rowElems.get(0).getText()).toMatch('/Col1/');
});

the following error message is displaying. Message: TypeError: Object [object Object] has no method 'findElements'

解决方案

Your grid setup is ok, but for the sake of a shortcut:

var grid = $$('.k-grid-content tr');

Regarding your question, avoid findElements and use chaining element or in this case all Protractor feature. But I'll use $$ shortcut again:

grid.each(function(row) {
  var rowElems = row.$$('td');
  expect(rowElems.count()).toBe(3);
  expect(rowElems.get(0).getText()).toMatch('/Col1$/');
});
