Protractor - How to resolve the promise to get number output - protractor

Question

I have the following method in my helper class. I need the method to return the rowNum of Number type. But I always get a Promise when i call the method. I want to see the number when I call the method.
getRowNum(table, colNum, searchText) {
let rowNum = -1;
return table.all(by.css("tbody tr td:nth-child(" + colNum + ")")).map(function (element) {
return element.getText();
}).then(function (textArray) {
for (var i in textArray) {
if (textArray[i].trim().indexOf(searchText) != -1) {
console.log(i);
console.log(textArray[i]);
rowNum = i + 1;
}
}
return rowNum;
});
});
//I'm using it in my other js file like this
let rowNum = helper.getRowNum($("div.sponsor-table table"), 2, "some text");

Answer 1

Have you tried this?
getRowNum = (table, colNum, searchText) => {
let rowNum = -1;
let text;
table.all(by.css("tbody tr td:nth-child(" + colNum + ")")).map(function (element) {
return text = element.getText();
})
.then(function () {
for (var i in text) {
if (text[i].trim().indexOf(searchText) != -1) {
console.log(i);
console.log(text[i]);
rowNum = i + 1;
break;
}
}
return rowNum;
});
};
Let me know if it works
