javascript - js function for multiple variables -


so, have 2 js variables use lot:

var rhpp = jquery(this).parents('.rhp'); var rhp_id = rhpp.data("pi");

for example:

function my_function_1 (){    jquery(document).on('click', '.button_1', function (e) {       var rhpp_1= jquery(this).parents('.rhp');       var rhp_id_1 = rhpp_1.data("pi");          //do    }); } function my_function_2 (){    jquery(document).on('click', '.button_2', function (e) {       var rhpp_2 = jquery(this).parents('.rhp');       var rhp_id_2 = rhpp_2.data("pi");          //do    }); } function my_function_3 (){    jquery(document).on('click', '.button_3', function (e) {       var rhpp_3 = jquery(this).parents('.rhp');       var rhp_id_3 = rhpp_3.data("pi");          //do    }); }

because of it, want make function can reuse:

function rhp_parent(a, b) {     var = jquery(this).parents('.rhp');     var b = a.data("pi"); }

then, rhp_parent("rhpp", "rhp_id");

of course, not right. not familiar how make function variables.

could show me?

thanks!

you create function returns both of values.

function getrhpparent(element) {   var rhpp = jquery(element).parents('.rhp');   return {     rhpp: rhpp,     rhpp_id: rhpp.data("pi")   }; }  // usage var temp = getrhpparent(this); var rhpp = temp.rhpp; var rhp_id = temp.rhp_id;

ios - Realm over CoreData should I use NSFetchedResultController or a Dictionary? -

i'm working on app using core data , nsfetchedresultcontroller many reasons switch use realm. saw there "realm version" of nsfetchedresultcontroller on github wouldn't compatible current code using core data. the view controller displaying list of people same school, address book. list sublist of people studied in same city. so thinking make 1 unique request database retrieve list of people , filter locally list within 1 dictionary per school [string: anyobject] string section name within tableview , anyobject array of people. first solution, make nsfetchedresultcontroller each school predicate filtering location. delete actions etc.. handled delegates -> not compatible realm create dictionaries , update them each actions... -> works realm it's annoying code. any better solution? edit: i need clarify request: i'd write class inherit uitableviewcontroller. this class has list of people sorted in alphabetical order the tableview has ...
