Passing a variable through Java Script Executor in selenium Webdriver

[visha...@gmail.com]

Hi 

I have a date picker field in the webpage. I am sending the values in the field with the help of java script executor in my java code. I would like to make that field data driven and pass the values through variables. I have tried in the following way:

String date1=values[2]+"/"+values[3]+"/"+values[4]+" 09:30am";

String date2=values[5]+"/"+values[6]+"/"+values[7]+" 06:30pm";

executor.executeScript("document.getElementById('rangedate__Datepicker1').value = date1");

executor.executeScript("document.getElementById('year-rangedate__Datepicker1').value = values[4]");

executor.executeScript("document.getElementById('month-rangedate__Datepicker1').value = month(values[3]");

executor.executeScript("document.getElementById('day-rangedate__Datepicker1').value = values[2]");

but i get the following error, " org.openqa.selenium.WebDriverException: JavaScript error". Can you please tell me how can i make send the values through variables in the above commands?

You have a error in your javascript:

    month(values[3]");

Looks like you are missing a closing parenthesis.

Hi Sean

I corrected the missing parenthesis, but still i get the same error at this line:

executor.executeScript("document.getElementById('rangedate__Datepicker1').value = date1");

What you are doing looks pretty sound, so try this: take the javascript that you believe is running, substituting the variables that WebDriver would substitute, and run it directly in your browser's javascript console.  WebDriver doesn't do anything special when running javascript, so if you are getting a javascript error, you should see it when running the commands by themselves, and perhaps get a better idea of what is going wrong.

Hi Sean

I believe that problem is while passing a value through a Java variable

String date1=values[2]+"/"+values[3]+"/"+values[4]+" 09:30am"

executor.executeScript("document.getElementById('rangedate__Datepicker1').value = date1");

Fore example in the above statement date1 is the java variable that we are passing through a javascript call and which believe is causing the error, because when give a static value in the place of date1 in the javascript call, the script runs without any error.? 

Is there any way through which i can make my java script call data driven?

Hi,


Your code should look as below.

executor.executeScript("document.getElementById('rangedate__Datepicker1').value ='" + rangeDateVar + "';");
executor.executeScript("document.getElementByIdyear-rangedate__Datepicker1').value ='" + yearDateVar + "';");
executor.executeScript("document.getElementById('month-rangedate__Datepicker1').value ='" + monthDateVar + "';");
executor.executeScript("document.getElementById('day-rangedate__Datepicker1').value ='" + dayDateVar + "';");


Now write whatever logic u want to initialize the variables. You want to read values[] you can read. Do whatever you want just initialize below variables to correct values and use the above code. It will work.

String rangeDateVar = "value you want to pass" , yearDateVar="value you want to pass"  , monthDateVar ="value you want to pass" , dayDateVar ="value you want to pass" ;

The scope of your Java variables is not shared with JavaScript, so you can't reference them the way you are trying here.

Pass a variable number of arguments to executeScript and reference them via the arguments array in javascript:

String date1=values[2]+"/"+values[3]+"/"+values[4]+" 09:30am"

executor.executeScript("document.getElementById('rangedate__Datepicker1').value = arguments[0]", date1);

This is the safest way to pass variables to your javascript.  A less-safe but perhaps more-readable alternative is string concatenation:

String date1=values[2]+"/"+values[3]+"/"+values[4]+" 09:30am"

executor.executeScript("document.getElementById('rangedate__Datepicker1').value = '" + date1 + "'");

In this case, you need to make sure to quote your strings the way I have done above.

Thank you Sean, I was able to execute the script by the changes you had suggested.
