.//*[@id='dp1445260078674']

these are the xpaths that are created every time I refresh my page. How can I locate/find such an element during my run test. Any help will be highly appreciated.

下面是该字段的HTML代码.

Below is the HTML code for the field.

<div class="form-group event-date">
    <div class="input-group">
        <input id="dp1445260154173" class="form-control ng-pristine ng-
        untouched ng-valid ng-isolate-scope hasDatepicker" 
        enter-action="datePickerEnter(event)" allow-empty=""
        has-datepicker="" ng-model="eventSeries.newEvent.date" 
        placeholder="Event Date"/>

        <span class="input-group-addon">
            <i class="fa fa-calendar"/>
        </span>
    </div>
</div>

推荐答案

通常，当ID或Class属性是动态的时，您需要使用以下属性来查找它们:其他属性/取决于它们对静态标记的依赖.

Usually when ID or Class attributes are dynamic, you need to look for them using: other attributes/by their dependence to static tags.

以下是在Gmail中查找撰写"按钮的示例.它具有:-动态ID-动态类-一个静态唯一属性

Here is an example of looking for a "Compose" button in Gmail. It has: - Dynamic ID - Dynamic Class - One static unique attribute

这是HTML代码:

<div class="T-I J-J5-Ji T-I-KE L3" tabindex="0" role="button" style="-moz-user-select: none;" gh="cm">COMPOSE</div>

所以我的xpath是:

So my xpath would be:

//div[@gh='cm']

或者假设您正在寻找Gmail上的发送邮件"按钮.它具有:-动态ID-动态类-一个静态唯一属性

Or imagine that you are looking for a "Send message" button on Gmail. It has: - Dynamic ID - Dynamic Class - One static unique attribute

HTML代码:

<div id=":ly" class="T-I J-J5-Ji aoO T-I-atl L3" tabindex="1" role="button" style="-moz-user-select: none;" data-tooltip="Send ‪(Ctrl-Enter)‬" aria-label="Send ‪(Ctrl-Enter)‬" data-tooltip-delay="800">Send</div>

此示例使用CSS选择器:

This example uses CSS selector:

[aria-label*='Enter)']

这里的规则是，当动态对象是动态对象时，请使用静态对象作为参考.

the rule here is, when something is dynamic, look for it by using something static as a reference.

在您的情况下，它将是:

In your case it will be:

//div[@class="form-group event-date"]/input

如果您的div类不是动态的，则可以正常工作.

works if your div-class is not dynamic.
