如何突破量角器的for循环? [英] How to break out of for loop in protractor?

问题描述

这是我的代码-

formElements[0].findElements(by.repeater(repeater)).then(function(items){
            console.log(i, '>>>>>>>>>.No of items in the list --- '+items.length);
            (function(items){
                for(var x1=0; x1<itemsToBeSelected.length; x1++){
                    console.log(i, '>>>>>>.Looking for item --- '+itemsToBeSelected[x1]);
                    skip = false;
                    (function(items, x1){
                        for(var x2=0; x2<items.length; x2++){
                            (function(items, x2){
                                items[x2].getText().then(function(itemName){
                                   console.log(i, '>>>>..Verifying '+itemsToBeSelected[x1]+' with '+itemName);
                                   if(itemName == itemsToBeSelected[x1]){
                                       console.log(i, '>>>>>.Selecting the item --- '+itemName);
                                       items[x2].findElement(by.css('.regular-checkbox')).click();

                                   }
                                });
                            }(items, x2));
                        }
                    }(items, x1));
                }
            }(items));
        });

当条件itemName == itemsToBeSelected [x1]满足时，我想突破内部for循环.尝试使用标志，返回语句，但无法从循环中退出.

I want to break out of inner for loop when the condition itemName == itemsToBeSelected[x1] is satisfied. Tried using flag, return statements, but unable to break out from the loop.

请在代码中提出更正建议.

Please suggest corrections in the code.

推荐答案

 ptor.element.all(by.repeater(repeater)).then(function(products){
           console.log(i, '>>>>>>>>>.Products length --- '+products.length);
           async.each(products, verifyName, function(err){
               console.log('>>>>>>>>>>>err value --- '+err);
               expect(err).toBe(true);
               if(err){
                   console.log(i, '>>>>>>>>.Element is present');
               }else{
                   console.log(i, '>>>>>>>>.Element is not present');
               }
           });
            function verifyName(product, callback){
                console.log(i, '>>>>>>>>.Inside function verifyName');
                product.getText().then(function(name){
                    console.log('>>>>>>>>>>Looking for product --- '+name);
                    if(name==entityName){
                        console.log(i, '>>>>>>>>Verified the name - '+name);
                        callback(true);
                    }
                });
            }
    });

我们也可以借助async.each模块获得相同的结果.例如我已经发布了一个代码，试图在其中找到一个值.

We can achieve the same results with the help of async.each module as well. For e.g. I've posted a code in which i'm trying to find a single value.

因此，关于我的问题，我们可以在设置callback(true)之前单击或对元素执行任何操作.例如说在这里我们可以做-product.click();

So in relation to my question, we can click or perform any action on the element before setting callback(true). Say for e.g. here we could do - product.click();
