Question

I am using web_reg_save_param to get dynamic values, such as <input type="hidden" name="lt" value="foo" /> then I can use it like :

web_reg_save_param("HiddenValue1", 
        "LB/IC=<input type=\"hidden\" name=\"lt\" value=\"", 
        "RB/IC=\" />", 
        "Ord=1", 
        "Search=body", 
        LAST);

However, if the <input> of page is like this way:

<input type="hidden" name="lt" readonly />

the value is set dynamically by ajax script. How can I get the value? There is no "value" property for this <input>.

Was it helpful?

Solution

Correlation is for server returned values. As your value is generated by local JavaScript then you should either reproduce the algorithm in the language of your script to generate the value or use the facilities of LoadRunner to execute the JavaScript function which returns the value you seek.

Or....you can move "up the stack" for a virtual user type which will run the full client stack of the browser. This would include types TrueClient, GUI, Citrix and RDP.
