Browser and variable access by JavaScript


Storing variables in Selenium IDE

Selenium functions store, storeValue, and storeText store some data for later access.
Selenium uses a map called storedVars to store the data.
You can store strings. Example:

    store
    this text is a string
    variable1

You can use previously stored variables. ${varaiable_name} gives us access to the storedVars map. Example:

    store
    ${variable1} okay?
    variable2

* varaible2 will now be ‘this text is a string okay?’
You can use pure javascript expressions. With javascript{} we can use pure javascript:

    store
    javascript{Math.random()}
    random_variable

So you can access the storedVars map directly in a javascript expression:

    store
    javascript{storedVars['random_variable']}
    random_variable_copy

Storing variables in Selenium IDE
* random_variable and random_variable_copy should be exactly the same.
Note that if you use:

    store 0 zero

zero will be 0, but casted as a string. So later if you use for example:

    javascript{storedVars['zero']+1}

You will get ’01′ instead of ’1′.
So when you need 0 as an integer you should store your variables using javascript:

    getEval storedVars['zero'] = 0;

* getEval gets the result of evaluating the specified JavaScript snippet.
