使用knockout js从javascript调用webservice方法 [英] calling webservice methods from javascript with knockout js
问题描述
亲爱的,
i确实要求从javascript调用webservice方法。
i编写了如下代码。
在.asmx页面
[webmethod]
公开列表< substation> GetsubstationsData()
{
返回bcommon.GetSubstationdetails();
}
....
和aspx页面
< select data-bind =options:substationvalues,optionText:'substationname',optionvalue:'substationid',value:selectedsubstationid,optionscaption:'select变电站'/>
js文件中的
功能变电站(数据)
{
var self = this;
self.substationname = ko.observable(data.substationname);
self.substationid = ko.observable(data.substationid );
}
函数datamodel()
{
var self = this;
self.substationvalues = ko.observablearray([]);
self.selectedsubstationid = ko.observable();
fetchsubstationsdata = function(){
$ .ajax({
类型:'获取',
dataType:'json',
url: 'service1.asmx / GetsubstationsData',
成功:函数(数据){
//我的装订代码;
}
}
});
}
}
我也想在webservice中调用addmethod,因为我应该在上面的ajax调用中使用type作为'post'。???,上面的函数不能正常工作对我来说
显示请求的网址格式不支持...错误,我怎么能实现这个...请帮我解决这个问题。

类型:'获取',
dataType:'json',
url:'service1 .asmx / GetsubstationsData',
成功:函数(数据){
//我的绑定代码;
}
}
});
}
}
