问题描述
此函数绑定孔类别,但我不会绑定单个类别子类。
<! - ko foreach:{data:ParentCatagories,as:' parent'} - >
< img data-bind =attr:{alt:parent.CategoryName,src:parent.CategoryImage} />
<! - ko foreach:{data:$ parent.getsubCatagories(parent.CategoryId) ,as:'child'} - >
<! - / ko - >
< br $>
self.cols = ko.observableArray();
self.getsubCatagories = function(obj){
$ .ajax({
url:'/ api / Catagory',
cache: false,
类型:'GET',
contentType:'application / json; charset = utf-8',
数据:{CatId:obj},
成功:函数(数据){
alert(数据。长度);
$ .each(数据,函数(键,值){
Catagory.CategoryName = value.CategoryName;
Catagory。 parentId = value.parentId;
Catagory.PostCount = value.PostCount;
Catagory.CategoryImage = value.CategoryImage;
Catagory.CategoryChangeSource = 城市;
Catagory.CategoryId = value.CategoryId;
self.cols.push(value);
});
}
});
返回self.cols;
};
This function bind hole catagory but i wont to bind a single catagory subcatagory.
<!-- ko foreach: {data: ParentCatagories ,as :'parent'} -->
<img data-bind="attr:{alt: parent.CategoryName, src: parent.CategoryImage}" />
<!-- ko foreach: {data: $parent.getsubCatagories(parent.CategoryId) ,as: 'child' } -->
<!-- /ko -->
self.cols = ko.observableArray();
self.getsubCatagories = function (obj) {
$.ajax({
url: '/api/Catagory',
cache: false,
type: 'GET',
contentType: 'application/json; charset=utf-8',
data: { CatId: obj },
success: function (data) {
alert(data.length);
$.each(data, function (key, value) {
Catagory.CategoryName = value.CategoryName;
Catagory.parentId = value.parentId;
Catagory.PostCount = value.PostCount;
Catagory.CategoryImage = value.CategoryImage;
Catagory.CategoryChangeSource = "City";
Catagory.CategoryId = value.CategoryId;
self.cols.push(value);
});
}
});
return self.cols;
};
推荐答案
parent.getsubCatagories(parent.CategoryId) ,as:'child'} - >
<! - / ko - >
< br $>
self.cols = ko.observableArray();
self.getsubCatagories = function(obj){
parent.getsubCatagories(parent.CategoryId) ,as: 'child' } -->
<!-- /ko -->
self.cols = ko.observableArray();
self.getsubCatagories = function (obj) {
.ajax({
url:'/ api / Catagory',
cache:false,
类型:'GET',
contentType:'application / json; charset = utf-8',
数据:{CatId:obj},
成功:函数(数据){
alert(数据。长度);
.ajax({
url: '/api/Catagory',
cache: false,
type: 'GET',
contentType: 'application/json; charset=utf-8',
data: { CatId: obj },
success: function (data) {
alert(data.length);
.each(数据,函数(键,值){
Catagory.CategoryName = value.CategoryName;
Catagory.parentId = value.parentId;
Catagory.PostCount = value.PostCount;
Catagory.CategoryImage = value.CategoryImage;
Catagory.CategoryChangeSource =City;
Catagory.CategoryId = value.CategoryId;
self.cols.push(value);
});
}
});
返回self.cols;
};
.each(data, function (key, value) {
Catagory.CategoryName = value.CategoryName;
Catagory.parentId = value.parentId;
Catagory.PostCount = value.PostCount;
Catagory.CategoryImage = value.CategoryImage;
Catagory.CategoryChangeSource = "City";
Catagory.CategoryId = value.CategoryId;
self.cols.push(value);
});
}
});
return self.cols;
};
