KnockoutJS变动表型号到控制器

Question

我有一个绑定用foreach

<td> 
         <input class='required' type="text" data-bind="value: muhasebekodu" id="muhasebekodu" /></td> 
        <td> 
         <select data-bind="options: gidertipleri, value: selectedOptionValue" onchange="SetCodeField(this.value);" id="muhcodes" name="muhcodess"></select></td> 

而且这样

var self = null; 
    var viewModel = null; 
    $(document).ready(function() { 
     var giderlers = JSON.parse(document.getElementById('ContentPlaceHolder1_hdnOutgoingTypes').value); 
     var selectedGider = document.getElementById('ContentPlaceHolder1_hdnOutgoingTypesSelected').value; 
     var odemetipleri = JSON.parse(document.getElementById('ContentPlaceHolder1_hdnFirmPaymentTypes').value); 
     var selectedOdemeTipi = document.getElementById('ContentPlaceHolder1_hdnFirmPaymentTypesSelected').value; 
     var GiftModel = function (gifts) { 
      self = this; 
      self.gifts = ko.observableArray(gifts); 

      self.addGift = function() { 
       self.gifts.push({ 
        muhasebekodu: ko.observable().extend({ notify: 'always' }), 
        gidertipleri: giderlers, 
        selectedOptionValue: ko.observable(selectedGider), 
        faturano: "", 
        matrah: "", 
        kdv: "", 
        geneltoplam: "", 
        kdvtipleri: ["0", "1", "8", "18"], 
        selectedOKDVptionValue: ko.observable("0"), 
        odemeseklitipleri: odemetipleri, 
        selectedOOSTptionValue: ko.observable(selectedOdemeTipi), 
        aciklama: "", 
       }); 
      }; 

      self.removeGift = function (gift) { 
       self.gifts.remove(gift); 
      }; 

      self.save = function (form) { 
       alert("Could now transmit to server: " + ko.utils.stringifyJson(self.gifts)); 
       // To actually transmit to server as a regular form post, write this: ko.utils.postJson($("form")[0], self.gifts); 
      }; 
     }; 


     viewModel = new GiftModel([ 
      { muhasebekodu: ko.observable().extend({ notify: 'always' }), gidertipleri: giderlers, selectedOptionValue: ko.observable(selectedGider), faturano: "", matrah: "", kdv: "", geneltoplam: "", kdvtipleri: ["0", "1", "8", "18"], selectedOKDVptionValue: ko.observable("0"), odemeseklitipleri: odemetipleri, selectedOOSTptionValue: ko.observable(selectedOdemeTipi), aciklama: "" }, 
     ]); 
     ko.applyBindings(viewModel); 

     // Activate jQuery Validation 
     //$("form").validate({ submitHandler: viewModel.save }); 


     $(".faturanoinp").bind('keyup', function (e) { 
      $(this).val($(this).val().toUpperCase()); 
     }); 

    }); 

我想设置我的muhasebekodu输入模式videmodel一个dropdownbox当用户改变下拉控制在同一屏幕上，我写下了jscript。它已经改变了模型的新的价值，但它不是apearing上控制

function SetCodeField(e) { 
     var mcode = document.getElementById('ContentPlaceHolder1_hdnmuhasebekodlari').value; 
     var mcodes = mcode.split(","); 
     for (i = 0; i < mcodes.length; i++) { 
      var namevalues = mcodes[i].split(":"); 
      var name = namevalues[0]; 
      var value = namevalues[1]; 
      if (e == name) { 
       self.gifts()[self.gifts.length].muhasebekodu.value = value; 
       self.gifts()[self.gifts.length].muhasebekodu.extend({ notify: 'always' }); 
      } 
     } 
    } 

我有2个控制其中的一个改变了我想看到的总是绑定到视图模型的另一个控制。 self.gifts.XXX ='新值';我希望看到此上绑定控制

在敲除设置可观察的值是这样的：

self.gifts()[self.gifts.length].muhasebekodu(value);
