使用JavaScript访问通过自定义定位器策略定位的元素 [英] Accessing elements located by custom locator strategy with Javascript

问题描述

我有以下问题:

• 我有一个隐藏的复选框，还有一层用于使它变得漂亮又有光泽
• 我可以通过访问其ID轻松更改其值，但是我还需要使用我的自定义定位器(使用xpath(必须保持可变))来访问此元素

所以，这是我的脚本:

Custom Select Checkbox    id=my_checkbox        #that works fine
Custom Select Checkbox    customLocatorStrat    #that doesn't work at all

*** Keywords ***
Custom Select Checkbox
    [Arguments]    ${locator}    ${timeout}=${global_timeout}
    Execute Javascript    document.getElementById("${resultLocator}").checked = true;
    OR
    ${el}.checked = true;     #need to get the ${el} variable if the ${locator is not an id}


My Custom Locator
    [Arguments]    ${criteria}    ${tag}    ${constraints}
    ...     #assembling xpath
    ${el}=    Get Webelements    xpath=${path}
    [Return]    ${el}

定位器策略没有问题-可以正常工作.我只需要在自定义选择复选框"关键字中使用它/强制使用它即可.我需要获取$ {el}变量，并且考虑到有不止一个Custom Locator关键字直接调用它对我不起作用.您知道如何执行此操作吗?预先非常感谢.

There is no issue with the locator strategy - it workes fine. I only need to use it/force it in my Custom Select Checkbox keyword. I need to get the ${el} variable and considering there's more than one Custom Locator keyword calling it directly will not work for me. Any idea how to do this please? Many thanks in advance.

推荐答案

selenium2library中的自定义定位器需要通过Add Location Strategy

Custom locators in the selenium2library require activation through the Add Location Strategy [Doc]. This seems to me to be the missing from your example.

*** Test Cases ***
Test Case
    Add Location Strategy   custom  Custom Locator Strategy
    Page Should Contain Element custom=my_id

*** Keywords ***
Custom Locator Strategy 
    [Arguments]    ${browser}    ${criteria}    ${tag}    ${constraints}
    ${retVal}=    Execute Javascript    return
window.document.getElementById('${criteria}');      
    [Return]    ${retVal}
