javascript - Live data not submitting using MVC 4.5 unobtrusive validation -

-

we have form user can move items 1 multi-select box another. using mvc 4.5 , jquery validate microsoft's unobtrusive javascript.

the problem is, when submitting form, values within select boxes don't submitted because user doesn't know after moving items have select items submission.

so solution sounds easy: use jquery select items upon submit.

after doing research (thanks stackoverflow community), able discover necessary jquery code intercept submit process. however, problem arises in when code selects items, pre-existing items in select box selected. live (dynamic) items have been moved not selected.

here code first used:

$('#userprofileform').bind('invalid-form.validate',function(){     $(this).find('.selectbox option').each(function (i) {         $(this).attr("selected", "selected");     }); });

we discovered using bind doesn't work live should:

$('#userprofileform').live('invalid-form.validate',function(){     $(this).find('.selectbox option').each(function (i) {         $(this).attr("selected", "selected");     }); });

however, using jquery 1.9 , live function has been removed. has been replaced this:

$(document).on('invalid-form.validate', 'form', function () {     $(this).find('.selectbox option').each(function (i) {         $(this).attr("selected", "selected");     }); });

however, still doesn't work. replaced selection function alert see if works @ all:

$(document).on('invalid-form.validate', 'form', function () {     alert('test'); });

an alert not pop up. ideas?

additional info

for wondering why i'm referencing invalid-form.validate because testing invalid form data. same scenario apply if valid form data. haven't gotten point on how bind live data valid form submission process either.

after inspecting elements, noticed jquery adding selected attribute options. however, options weren't highlighted. had me thinking maybe jquery call add selected attribute wrong.

after experimentation, discovered wrong. appears if use attr function of jquery, doesn't set option selected in dom. using prop function does.

here code:

$(document).on('submit', 'form', function (e) {     $(this).find('.selectbox option').each(function (i) {         $(this).prop("selected", true);     }); });

this allows form select options selected upon form submission whether submit handler valid or not. if want select based on invalid info, use this:

$('form').bind('invalid-form.validate', function () {     $(this).find('.selectbox option').each(function (i) {          $(this).prop("selected", true);     }); });

enjoy!

java - Copying object fields -

-
what best way of copying classes when need have 2 independent variables? have simple class: public class myclass { boolean = false; string b= "not empty"; } do need make method : assign(myclass data ) { a= data.a; b= data.b; } is there automatic method copy (duplicate) objects in java? do need make method : pretty close. instead of making method, should make constructor. such constructors called copy constructor , , create them this: myclass(myclass data) { = data.a; b = data.b; } and create copy of instance, use constructor this: myclass obj1 = new myclass(); myclass obj2 = new myclass(obj1); copy constructor can tedious : using copy constructor create deep-copy can tedious, when class has mutable fields. in case, assignment create copy of reference, , not object itself. have create copy of fields (if want deep copy). can go recursive. a better way create deep copy serialize , deserialize object. why not use clone()? ...

c++ - Clear the memory after returning a vector in a function -

i have function processes , stores lot of data in , returns results vector of class. amount of data stored in function tremendous , want clear storage memory of function after finished job. necessary (does function automatically clear memory) or should clear memory function? update: vector<customers> process(char* const *filename, vector<int> id) { vector<customers> list_of_customers; (perform actions) return list_of_customers; } variables defined locally within function automatically released @ end of function scope. destructors objects called, should free memory allocated objects (if objects coded correctly). example of such object std::vector . anything you've allocated new must have corresponding delete release storage. try avoid doing own allocation , use raii instead, i.e. containers or smart pointers.
