Vugen 11.52 Firefox TruClient: evalXPath issue

[drenze]

I'm having an issue with TruClient under Vugen 11.52 identifying an object using JavaScript ID method and evalXPath.

I have a link that I need to identify and select based on a parameter - it's the name of a specific customer.

I assign the parameter name to a variable at the beginning of my TruClient script when I assign all my variables...

var custName = LR.getParam('Customer Name');

 ...and then I attempt to use it to identify and click on the object by setting ID Method to JavaScript and using the following statement:

evalXPath("//a[text()=\"" + custName + "\"]")

 ...which fails to identify the correct object on the page. However, the following evalXPath statement works just fine every time:

evalXPath("//a[text()=\"John Smith\"]");

When generate an alert box to show the XPath statement I'm building that's not working, it's identical to the one that is working.
 

I'd ask my 13-year-old what I'm doing wrong, but he's not handy at the moment. Help?

Sounds like custname did not capture a value. Maybe its placed before the value is captured.

Sorry - I didn't make myself clear. My bad.

I'm specifying the value of the 'Customer Name' parameter in the script parameters - it's not being captured. I also threw a window.alert(custName) into the script prior before executing that evalXPath statement to validate that the custName wasn't blank (and also did window.alert(xpath) for that matter to validate that I'd built it correctly).

I think you need double quotes around your parameter.

var custName = LR.getParam("Customer Name");

I should have come back and marked this resolved, since I just found my own question again on a search. From the evalXPath context, it is necessary to use `ArgsContext` to reference global variables in the script. I.e.:

evalXPath("//a[text()=\"" + ArgsContext.custName + "\"]")

will yield the desired results.

Hi drenze

I applied the changes suggested by you, however i am getting the error saying. there are so many sich object and loadrunner is not able to identify the object uniquikly. 

Waiting for your reply.

Thanks in advance.

Hi all,

Can anyone please explain me the format of the below code. Why we are using " before + sign and "\"after + sign.

This code is working fine for me but i want to know the format for this.

evalXPath("//a[text()=\"XYZ"+ArgsContext.z+"\"]")

Thanks,

Vivek

In the example below, green text is JS code, while the red text sections are strings (in this case, an XPath expression).

The blue + signs are concatenating the JS value into the string parameter. 

evalXPath("//a[text()=\"XYZ"+ArgsContext.z+"\"]")

Note that the back-slashes are escaping characters.

Hi Vivek,

I strongly suggest to learn about string manipulation in JS and specifically the topic of escaping in the link I sent above.
