Question

我有这段代码：

// Change frame
btnName.frame = CGRectMake(screenWidth/3, screenHeight/2, 100, 100)
// Change center of button
btnName.center = CGPoint(x: screenHeight/2, y: screenWidth/2)

这是一种按属性“名称”搜索的简单方法。但它不是通用的，因为它带有标记by.addLocator('Name', function(spanText, opt_parentElement) { var using = opt_parentElement || document; var td = using.querySelectorAll('td'); return Array.prototype.filter.call(td, function(teg) { return teg.getAttribute("Name") === spanText; }); });的搜索元素。我怎样才能使它独立于标记？

您可以向定位器添加任意数量的参数，因此在CREATE PROCEDURE get_output @Date DATE ,@ID INT ,@Output INT OUTPUT -- 1 true , 0 false AS BEGIN SET NOCOUNT ON; DECLARE @Count INT; SELECT @Count = COUNT(*) FROM TableName WHERE CAST(DATEADD(WEEK, DATEDIFF(WEEK, 0, @Date), 0) AS DATE) = CAST(DATEADD(WEEK, DATEDIFF(WEEK, 0, [Date]), 0) AS DATE) AND ID = @ID GROUP BY CAST(DATEADD(WEEK, DATEDIFF(WEEK, 0, [Date]), 0) AS DATE) IF (@Count < 2) SET @Output = 1; ELSE SET @Output = 0; END之后您可以包含spanText。您可以更进一步，不要将自己置于使用仅标记参数的范围内，而是使用tagName支持的任何选择器：

querySelectorAll()

用法：

by.addLocator('Name', function (spanText, selector, opt_parentElement) {
    var using = opt_parentElement || document;
    var els = using.querySelectorAll(selector);
    return Array.prototype.filter.call(els, function (el) {
        return el.getAttribute('Name') === spanText;
    });
});
