函数内部的函数用于循环错误 [英] function inside for loop errors out in protractor

问题描述

数组长度为4，当我运行循环3时，它运行正常，没有任何错误。但是，当我运行for循环4次时，它会出错。

Array length is 4,when i ran the loop for 3, it runs fine without any errors. But when i run the for loop for 4 times it errors out.

for(var userI=0;userI<userArray.length;userI++) {

    var userEmail = userArray[userI].UserEmail;
    var userFName = userArray[userI].FirstName;
    var userMName = userArray[userI].MiddleName;
    var userLName = userArray[userI].LastName;
    //Check for the user and create the user if the user is not created.
    (function (uEmail,uFName,uMName,uLName) {
        logger.info("FirstName inside the function::"+tFName);
        //Check and create user
        queryUserEmail(uEmail).then(function (checkFlag) {
            if (checkFlag === true) {
                //User already Exists, Log it
                logger.info('User '+uEmail+' already Existed');
            } else {
                CreateClassElements.click();
                //Now create user
                createUserPage.createUser(uEmail,uFName,uMName,uLName);
            };
            //Clear the element
            emailQueryElement.clear();
        });
    }(userEmail,userFName,userMName,userLName));
};

当我在没有 queryUserEmail 功能的情况下运行循环时，它运行正常4时间

When i run the loop without the queryUserEmail function it runs fine for 4 times

for(var userI=0;userI<userArray.length;userI++) {

    var userEmail = userArray[userI].UserEmail;
    var userFName = userArray[userI].FirstName;
    var userMName = userArray[userI].MiddleName;
    var userLName = userArray[userI].LastName;
    //Check for the user and create the user if the user is not created.
    (function (uEmail,uFName,uMName,uLName) {
        logger.info("FirstName inside the function::"+uEmail);   
    }(userEmail,userFName,userMName,userLName));
};

任何建议？

推荐答案

你看起来像是一个错字：

You have what looks to be a typo:

CreateClassElements..click();

也许该段代码仅在第4次迭代时运行。

Perhaps that segment of the code is only running on the 4th iteration.
