How to add different parameters to the href link when looping through DOM?

when I am looping DOM, how do I add a looped value to the href in the a tag, and then click on the a tag, and the past value of the page jump transfer is also different?
I"ve tried using the $(".bl"). Attr ("href", xxxxx) method, but the href of each a tag is the same, and the resulting value is the last value looped out.
what should I do? every time I click on the link of a tag, the parameters are different.

. Why don't you just change the href every time you cycle?
(and this code is too stingy, what can you see? it can't be changed. )


$('bl') [index] take
