我尝试在量角器中使用IndexOf方法。而且我无法返回数值而非Promise。
PsGrid.prototype.getQuickFilterByName = function(name) {
var num;
num = this.all(by.xpath(".//tr[contains(@class,'n-grid__head-row')]/th[contains(@class,'n-grid__title')]//div[contains(@class,'n-grid__text')]")).getText().then(function(textArray){
return textArray.indexOf(name) + 2;
});
expect(num).toEqual(8); // num == 2
console.log("sdf" + num); // num == Promise::3138 {[[PromiseStatus]]: "pending"}
return this.element(by.xpath('.//tr[2]/td[' + num + ']//input')); //protractor can't find element
};

我尝试编写addLocator方法，但我认为我有一些误解。

是的，num是一个承诺。所以如果你想对它做任何事情，它需要进行then回调;而你的功能只能回报另一个承诺。
PsGrid.prototype.getQuickFilterByName = function(name) {
return this.all(by.xpath(".//tr[contains(@class,'n-grid__head-row')]/th[contains(@class,'n-grid__title')]//div[contains(@class,'n-grid__text')]")).getText().then(function(textArray){
return textArray.indexOf(name) + 2;
}).then(function(index) {
expect(index).toEqual(8);
console.log("sdf" + index);
return this.element(by.xpath('.//tr[2]/td[' + index + ']//input'));
});
};
