Hi ,

I need help to make URL dynamic which is get to next page.
Details scenario,
1. Have 3 pages.
1st page to 2nd page request occur.
In 2nd page after click on ok button, 1 parameter generated by application, which could not be in any HTML page.
After that that request get by GET method in third page.

So I have to capture that dynamic value generated by application, how can I do that?

Hi,
Thanks for the very useful tip.

One note: “Save time by using lr_paramarr functions to extract the values from the parameter array you created with web_reg_find.” likely should end with “… you created with web_reg_save_param(”ItemID_array…” ?

Scott’s solution is quick n dirty work around and does not scale beyond a predefined limit. I’ve been using web_custom_request for generating dynamic name-value pairs and is a very elegant solution.

The code above would be complete if you add “convert=HTML_TO_URL” argument to the web_reg_save_param call that builds ItemID_array, so that the reserved characters like &, ?, @ etc. within the captured values (if any) will be converted to percent encoding.

Hi,
Thanks this is a great topic. I have been trying to find a way to get this done without having to change the arguments in the web_submit_data functions whenever the project team asks to change the number of name-value pairs that they want me to run the test with.

Btw, I would like to ask if the lr_paramarr_idx and lr_paramarr_len is a function found in higher LR versions. I have tried looking for it in LR8.1 function library but these functions do not exist. Is there a work-around for this without having to use C string functions? Thanks!

[Stuart's Reply: Yes, the lr_paramarr functions are fairly recent. They are definitely not in LoadRunner 8.1.4.]
