jquery - Javascript Control form fields posted to server -


i have backone js model defined below;

var class = basemodel.extend({         idattribute: "classid",         urlroot: "api/class",         defaults: {             "person": null,             "classurl": null,             "classid": null         } }

here person object/class has 2 attributes; personname, personid

i have ui form has 2 fields;

  1. dropdown (called personname) : user can select list of options
  2. textbox (called classurl)

in js code, setting json below;

    var myjson = {         person : new person(             {             "personid": $('#personname option:selected').data('personid'),             "personname": this.$('#personname').val()             }         ),           classurl: this.$('#classurl').val() }

then do;

this.model.save(myjson, { url: success: }

however json gets posted looks like;

{ person:, classurl: personname: }

i not want additional personname (corresponding dropdown) posted .

just add, have changeaction called on change of form field validation. here have;

changeaction: function (event) {     var self = this;     var target = event.target;     var change = {};      target.value = $.trim(target.value);     change[target.name] = target.value;      var tpmmodel = this.model;     tpmmodel.set(change);      var check = tpmmodel.validateitem(target.id);     if (check.isvalid === false) {     self.addvalidationerror(target.id, check.message);     } else {     self.removevalidationerror(target.id);     } }

how handle this?

when need specify content want post using backbone model, need use "data" inside save method. tells backbone post server using specified data inside {}. this.

  this.model.save(data: {"parameter1":"parameter1"   ,"parameter2":"parameter2" })

or 

this.model.save(data: json.stringify(personobject))

opencv - DataType<cv::detail::deriv_type>::depth what is it used for -

i wondering why line used in lucas kanade tracker in opencv: datatype<cv::detail::deriv_type>::depth can explain me? in opencv, depth of mat refers type of data contained in mat 's data buffer. represented integer values correspond given data type. these integers commonly abstracted appropriate macro definition (e.g. uchar data represented macro cv_8u ). cv::datatype type-traits class provides method obtain corresponding integer value without having memorize macro means data type. there few cases user code needs use datatype::depth . more common datatype::type . a simple example shows 1 possible use of datatype::depth : cv::mat uchar_data = cv::mat::ones(3, 3, cv_8uc1); cv::mat float_data; uchar_data.convertto(float_data, cv::datatype<float>::depth); // ^^ equivalently replaced // cv_32f macro float_data.at<float>(0,1) += 0.5f; std::cout << float_data << std::endl;...
