Question

这是迭代动态表的代码。

driver.findElements(By.xpath(`//*[@id="slide-wrapper"]/div/ui-view/search-activities/div/div[2]/table/tbody/tr`)).then(function(rows) {
                        console.log("NoofRowsinthetable" + rows.length);
                        var identifyvalue = "6/16/17 12:41 PM"
                        var datacount = 0;
                        for (var i = 1; i <= rows.length; i++) {
                            driver.findElements(By.xpath(`//*[@id="slide-wrapper"]/div/ui-view/search-activities/div/div[2]/table/tbody/tr[i]/td`)).then(function (cells) {
                                    console.log("NoofColumnsinthetable" + cells.length);
                                    for (var j = 1; j <= cells.length; j++) {
                                        driver.findElement(By.xpath(`//*[@id="slide-wrapper"]/div/ui-view/search-activities/div/div[2]/table/tbody/tr[i]/td[j]`)).getText().then(function (cell_text) {
                                            console.log(cell_text);
                                            if (identifyvalue === cell_text) {
                                                datacount = datacount + 1;
                                                console.log("Data count" + datacount);
                                            }
                                        })

First Forloop：即使有9列，Cells.length也会返回零。

如果我正在传递我作为弦乐的价值（tr [“+ i +”]）那么它只会返回第一行的长度，如果我没有通过'我'作为弦乐的价值然后，它正在退回专栏。长度为零。

Second For循环：如果我通过I和J作为字符串的值（tr [“+ i +”] / td [“+ j +”]），那么它只返回第一列的值

问题在于单引号。你是用单引号开始字符串，它应该以单一结束。尝试以下，

driver.findElements(By.xpath(`//*[@id="slide-wrapper"]/div/ui-view/search-activities/div/div[2]/table/tbody/tr`)).then(function(rows) {
                        console.log("NoofRowsinthetable" + rows.length);
                        var identifyvalue = "6/16/17 12:41 PM"
                        var datacount = 0;
                        for (var i = 1; i <= rows.length; i++) {
                            driver.findElements(By.xpath(`//*[@id="slide-wrapper"]/div/ui-view/search-activities/div/div[2]/table/tbody/tr[`+i+`]/td`)).then(function (cells) {
                                    console.log("NoofColumnsinthetable" + cells.length);
                                    for (var j = 1; j <= cells.length; j++) {
                                        driver.findElement(By.xpath(`//*[@id="slide-wrapper"]/div/ui-view/search-activities/div/div[2]/table/tbody/tr[`+i+`]/td[`+j+`]`)).getText().then(function (cell_text) {
                                            console.log(cell_text);
                                            if (identifyvalue === cell_text) {
                                                datacount = datacount + 1;
                                                console.log("Data count" + datacount);
                                            }
                                        })

当我在nodejs webdriver中使用for循环传递xpath中的值i时，列长度返回零
