我设置了一些变量来保存页面元素:
this.examStatusSelect = element(by.id('examStatusSelect'));
this.examTypeSelect = element(by.id('examTypeSelect'));
我有这个函数调用:
dom.checkGrid('* check', 0, [
[page.examStatusSelect, 0],
[page.examTypeSelect, 0],
]);
我想要做的是调用另一个这样的函数:
var Dom = function () {
var self = this;
this.getSelectOption = function (element, value) {
var id = element.locator_.value;
return element(by.xpath('//select[@id="' + id + '"]/option[@value = "' + value + '"]'));
}
this.checkGrid = function (label, expectedCount, params) {
it(label + ': Check for ' + expectedCount + ' grid rows', function () {
for (var i = 0; i < params.length; ++i) {
self.getSelectOption.apply(self, params[i]).click();
}
page.retrieveButton.click();
expect(page.row.count()).toBe(expectedCount);
});
}
但是我收到一个指向xpath行的奇怪错误。错误是
TypeError: Object is not a function
我看不出这意味着什么。有人可以建议我可能做错了吗?申请后我也不确定自我的目的是什么(?

您正在本地范围内重新定义element
。而是将输入参数命名为elem
,例如:
this.getSelectOption = function (elem /* local scope */, value) {
var id = elem.locator_.value; /* elem is local scope here */
/* element is from the not local scope
(might be global, could also be from a closure) */
return element(by.xpath('//select[@id="' + id + '"]/option[@value = "' + value + '"]'));
}
