问题描述
在基因敲除网站的文档上，他们说，当您从服务器取回数据时，您可以执行以下操作:
On the knockout.js site's documentation they say that when you get data back from the server you can do this:
// Every time data is received from the server:
ko.mapping.fromJS(data, viewModel);
我想将数据部分映射回我的对象模型.有可能吗?
I'd like to partially map the data back into my object model. Is that possible?
我有一个viewModel.jobs [i] .JobType子对象，所以我想做这样的事情:
I have a viewModel.jobs[i].JobType child object, so I'd like to do something like this:
ko.mapping.fromJS(data.jobType, viewModel.jobs[i].JobType);
...意味着我只想将来自服务器结果的jobType映射到该特定作业的JobType字段中.
... meaning I'd like to just map in the jobType from the result from the server into this specific job's JobType field.
...另外请记住:
// does not work because viewModel.jobs[i].JobType() is not a function.
viewModel.jobs[i].JobType(data.JobType);
推荐答案
此方法有效:
ko.mapping.fromJS(data.job，viewModel.jobs [i]);
ko.mapping.fromJS(data.job, viewModel.jobs[i]);
