javascript - Dynamically get value of input fields with jQuery and process them with PHP -

-

i working on page show different input fields, depending on selection user did.

example 1:

<input type="text" name="color" value="" id="5"> <input type="text" name="location" value="" id="6"> <input type="text" name="age" value="" id="7">

example 2:

<input type="text" name="color" value="" id="5"> <input type="text" name="destination" value="" id="8"> <input type="text" name="hours" value="" id="9"> <input type="text" name="date" value="" id="10">

question 1: how can input fields jquery when input fields dynamic?

question 2: on serverside, want process input fields value , id. how can make dynamic?

i know can done when fix, e.g.:

var color =  $('#color').val(); var destination = $("#destination").val();  var datastring = 'color=' + color + "&destination=" + destination; $.ajax({          type: "get",          url: "do_something.php",          data: datastring,          async: false,        success: function(data){           console.log('success');        } });

you can use .serialize() create data-string. dynamically grab data form , turn string you're attempting build:

$.ajax({          type: "get",          url: "do_something.php",          data: $("form").serialize(),          async: false,        success: function(data){           console.log('success');        } });

docs .serialize(): http://api.jquery.com/serialize

note, may need refine $("form") selection more specific if have more 1 form in dom.

as second question, should keep questions on 1 question per post. being said, should set id attribute value attribute instead, way passed php script when form submitted, id lost since it's not transmitted form.

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.
