I am trying to use the methods available within Codeceptjs to simply iterate rows of a table and select a row based on text existing in a particular cell of the current row being iterated.
The following code is in one of my page objects and partially works.
async selectSiteById(siteId) {
I.waitForElement('table');
for (let i = 1; i < 5; i++) {
let val = await I.grabTextFrom(`tbody tr:nth-child(${i}) td:nth-child(2)`);
if (val === siteId) {
I.say('Val' + val + ' -- Site Id ' + siteId)
within(`tbody tr:nth-child(${i + 1}) td:nth-child(1)`, () => {
I.click('input');
});
}
break;
}
},
The grabTextFrom pulls back the exact value I am after and stores it to val.
If the value of the parameter I pass in happens to be in the first row of the table, this works. However, my code only ever seems to be hitting the first row no matter what I do and I do not understand why?
Again, if the first row has the value of the parameter passed in, then my within method fires and checks the input box in the first column, exactly how I want it to do.
So, the two pieces of code I have for identifying the text I'm after in the given row works (mostly), and the code to click the check box in 'that' row also works.
If someone could help me understand why I cannot get this to loop through all rows of the table, I would hugely appreciate it.
Also, I can't seem to get codeceptjs to pull back the total number of tr in tbody as a simple array so I can use that as my length for the loop, so any pointers there would be awesome.
For this, I have tried - let rowCount = await I.grabNumberOfVisibleElements('tbody tr'); but does not seem to work.
I did try to move my break up one level as I initially thought it was in the wrong spot. When I did so, running my test results in the following error.

Lastly, for basic interaction with a table, when using codeceptjs, are you basically required to use a helper and then write the code using native Puppeteer? (I'm using puppeteer in my project)
<<<<<<>>>>>> UPDATE
Can anyone help me understand why you can't seem to iterate rows of a table with CodeceptJS? I have to be missing something. Here is my current code from a PageObject class and I don't understand what the first iteration happens successfully, but then fails.
async test() {
const totalRows = await I.grabAttributeFrom('tbody tr');
I.say('Total Rows: ' + totalRows.length);
for (let i = 1; i < totalRows.length; i++) {
I.say('Current row is: ' + i);
let str = await I.grabTextFrom(
`tbody tr:nth-child(${i}) td:nth-child(2)`,
);
I.say('String value from table is: ' + str);
if (str === 'IDR') {
I.say('Match found in row: ' + i);
within(`tbody tr:nth-child(1) td:nth-child(1) span span`, () => {
I.click('input');
});
break;
}
}
// I.say('Hello');
// let scores = [10, 15, 20, 30];
// for (let score of scores) {
// score += 3;
// I.say(score);
// }
},

Thank you! Bob
I ended up going the helper route and built out some generic functions to work with tables. Thought I would share in the event this is helpful to anyone out there. Attempting to do this with the built in codeceptjs methods was unreliable.

// use: this.helpers['helperName']
