Question

为Angular App编写e2e测试，但我似乎无法理解异步编程和承诺。我试图从第一列中获取每一行的值，并将其添加到数组中，最终将其从高到低排序，以获得最高值。我在解决我的rows.each的承诺时遇到了一些麻烦，errormsg是：＆＃39; TypeError：undefined不是函数＆＃39;

//This function will fetch the highest ID from the columns
this.getHighestScheduleId = (function(){
    //Array to collect the ID's in
    var idArray = [];
    //Collects all the rows in our table
    var rows = $$('#schedulesData');
    //Goes through each row
    rows.each(function(row){
        //Collect all the row's elements in rowElems
        var rowElems = row.$$('td');
        console.log(rowElems[0].getText());
    });
});

map()很适合这里：

rows.each(function(row) {
    var rowElems = row.all('td').map(function (td) {
        return td.getText();
    });

    // resolve the promise to see the output on the console
    rowElems.then(function (values) {
        console.log(values);
    });
});

将表中每行的列中的值收集到量角器中的数组中
