Jquery index () method code

The home page of the student's website has 19 repeater controls. Switch the tabs of the six Div blocks.

For tabs switching, you cannot write one by one :(CodeAs follows ....)Copy codeThe Code is as follows: $ (function ()
{
$ ("# Tabs A: eq (0), # tabs2 A: eq (0), # dbt_l_t_tabs A: eq (0), # dbt_r_t_tabs A: eq (0) "). addclass ("m_on ");
$ ("# Tabs A: GT (0), # tabs2 A: GT (0), # dbt_l_t_tabs A: GT (0), # dbt_r_t_tabs A: GT (0) "). addclass ("m_out ");
$ ("# Tabs a, # tabs2 A, # dbt_l_t_tabs A, # dbt_r_t_tabs a"). Each (function (){
$ (This). Mouseover (function (){
If ($ (this). hasclass ("m_out "))
{
VaR AB = $ (this). Closest ("Li"). Closest ("Div"). ATTR ("ID ");
VaR ulid = "Ul _" + AB;
VaR ARRA = $ ("#" + AB + "");
VaR E = ARRA. Index ($ (this ));
$ ("#" + AB + "A"). removeclass ("m_on"). addclass ("m_out ");
$ (This). removeclass ("m_out"). addclass ("m_on ");
$ ("#" + Ulid + "Ul"). Hide ();
$ ("#" + Ulid + "Ul: eq (" + E + ")"). Show ();
}
})
})
})

The index method of jquery is used to assign values to the 23 rows. Search for the index value of an element of an object in this object.
An official note: $ ('lil'). Index ($ ('# bar'); here, the index parameter is enclosed in single quotes. Always fails during the test .. I don't know why. Then, the object where $ (this) is located is defined: var ARRA = $ ("#" + AB + "");.
You can return the index successfully.
