Knockout 监控数组对象属性

代码:

 function Product(ProductID,ProductName,ProductNum,Result,Price) {
this.ProductID = ko.observable(ProductID);
this.ProductName = ko.observable(ProductName);
this.ProductNum = ko.observable(ProductNum);
this.Result = ko.observable(Result);
this.Price = ko.observable(Price);
}
 self.add = function (o) {
self.isDetail(true);
self.selectedItem(new Sale());
$.ajax({
url: "/api/CommonApi?API=GetProductListByBuy",
type: "get",
dataType: "json",
success: function (data) {
var list = data.ApiParamObj;
var arr = [];
$(list).each(function () {
var ProductNum = $(this)[].ProductNum;
var Result = $(this)[].Result;
var Price = $(this)[].Price;
var ProductID = $(this)[].ProductID;
var ProductName = $(this)[].ProductName;
//console.log(Price);
//self.ProductList().push(new Product(ProductNum, Result, Price));
arr.push(new Product(ProductID, ProductName, ProductNum, Result, Price));
//self.ProductList.push(new Product(ProductID, ProductName, ProductNum, Result, Price));
})
//console.dir(arr);
self.ProductList(arr);
//self.ProductList = ko.observableArray(arr); //console.log(self.ProductList().length);
//console.dir(self.ProductList());
}
});
$("#formDialog").valid();
}

对每一个属性进行监控,组成数组对整个数组进行监控

计算总数量,总金额

self.TotalNum = ko.computed(function () {
//console.log("ffff");
//console.dir(self.ProductList());
var total = ;
ko.utils.arrayForEach(self.ProductList(), function (item) {
if (item.Result()) {
var value = parseFloat(item.ProductNum());
if (!isNaN(value)) {
total += value;
}
}
});
return total.toFixed();
});
self.TotalAmount = ko.computed(function () {
var total = ;
ko.utils.arrayForEach(self.ProductList(), function (item) {
if (item.Result()) {
var value = parseFloat(item.ProductNum() * item.Price());
if (!isNaN(value)) {
total += value;
}
}
});
return total.toFixed();
})

html代码:

  <div class="row">
<div class="form-group col-xs-12">
<label class="control-label col-md-2">产品:</label>
<div class="col-md-10" data-bind="visible: ProductList().length > 0,foreach:ProductList">
<div class="dvcls">
<input type="checkbox" class="chk" data-bind="checked:Result,value:ProductID,attr:{ name: $index },enable:$parent.isDetail" />
<span data-bind="text:ProductName"></span>
&nbsp;&nbsp;价格:<span data-bind="text:Price"></span>
&nbsp;&nbsp;<input type="number" style="width:40px" min="" data-bind="value:ProductNum,valueUpdate:'keyup',visible:Result,enable:$parent.isDetail" />
</div>
</div>
</div>
