How to handle table data in Protractor - protractor

Question

In Protractor, how does one handle repeated content, from say a table? For example, given the following code, that kicks out a table with 3 columns: Index, Name and Delete-Button in each row:
<table class="table table-striped">
<tr ng-repeat="row in rows | filter : search" ng-class="{'muted':isTemp($index)}">
<td>{{$index+1}}</td>
<td>{{row}}</td>
<td>
<button class="btn btn-danger btn-mini" ng-click="deleteRow(row)" ng-hide="isTemp($index)"><i class="icon-trash icon-white"></i></button>
</td>
</tr>
</table>
And in my test I need to click the delete button based on a given name. What's the best way to find this in Protractor?
I know I could grab the rows.colum({{row}}) text, get the index of that, and then click on the button[index], but I'm hoping for a more elegant solution.
For example, in Geb, you could pass a row locator to a module, that would then dice up each row with column indicators. And that solution has me eyeing Protractors map method...

Answer 1

You can use map or filter. The api would look like this:
var name = 'some name';
// This is like element.all(by.css(''))
return $$('.table.table-stripe tr').filter(function(row) {
// Get the second column's text.
return row.$$('td').get(2).getText().then(function(rowName) {
// Filter rows matching the name you are looking for.
return rowName === name;
});
}).then(function(rows) {
// This is an array. Find the button in the row and click on it.
rows[0].$('button').click();
});

Here is how I am doing something similar in my application using Protractor against a Kendo grid:
I have a page object that has the following functions:
// Query all table rows (tr) inside the kendo grid content container
this.getGrid = function () {
return element.all(by.css('.k-grid-content tr'));
};
// Use the given rows element finder to query for the delete button within the context of the row
this.getDeleteButtonInRow = function (row) {
return row.element(by.css(".btn.delete"));
};
Then I use these functions in my test like so:
// Verify that a delete button appears in every row of the grid
var grid = pageObj.getGrid();
grid.each(function (row) {
var deleteButton = downloadsPage.getDeleteButtonInRow(row);
expect(deleteButton.isDisplayed()).toBe(true);
});

Here's my solution, based on #Andres solution, that I used in my page object:
this.deleteFriend = function(nameString) {
return this.rows.filter(function(row) {
// find the row with the name we want...
return row.$$('td').get(1).getText().then(function(name) {
return name === nameString;
});
}).then(function(filteredRows) {
filteredRows[0].$('i.icon-trash').click();
});
};
