涉及方法的 JavaScript 比较永远不会为真

Question

I have the following JavaScript logical condition using the ternary operator:

var columnheader = (elem.getText === "ID") ? (Page.TableColumn(elem.getText())) : (Page.TableColumn(toTitleCase(elem.getText())));

For some reason when elem.getText value is 'ID' with no whitespace it doesn't evalute the first expression only the second, is there something wrong in my syntax? I've checked and double checked!

Answer 1

getText is a function. In your code, you are comparing the function with "ID", not the result of the function call (getText() ).

Should be:

var columnheader = (elem.getText() ==="ID") ? (Page.TableColumn(elem.getText())) : (Page.TableColumn(toTitleCase(elem.getText())));
