如何使用javascript测试列表中的元素？

Question

Hi guys i am working on a apple UI Automation project where i have to test on a click of a button are elements in the list getting sorted properly or not ? can anyone help me to find how can i test it ?

Answer 1

A simple solution would be to iterate over the elements in the list and verify that each element is smaller than the next one:

function is_sorted(arr) {
var len = arr.length - 1;
for(var i = 0; i < len; ++i) {
    if(arr[i] > arr[i+1]) {
        return false;
    }
}
return true;

}

You will have to adapt this code to sort UIElements, in particular the clause below:

arr[i] > arr[i+1]
