剑道数据源参数图 [英] Kendo dataSource Parameter Map
问题描述
我是剑道新手.我遇到了模型绑定问题.当我用 firebug 调试时，它显示 options.models 是 undefined.因此，参数映射中的if"条件始终为 false，并且网格不会填充数据.但是当我删除参数映射部分时，它起作用了.我想，如果有人能解释一下kendo dataSource 中的参数映射，会很有帮助.谢谢你.
I am new to kendo. I'm having a problem with model binding. When i debug with firebug, it shows options.models is undefined. Because of that reason the "if" condition in parrameterMap is always false and grid doesn't populate the data. But when i remove the parrameterMap part, it works. I think, it's very helpful if somebody can explain about the parameter map in kendo dataSource. Thank you.
function GetDataSource() {
var PrjKy = $("#cmbPrjNm").val();

推荐答案
您可以在 参数映射
您应该使用 parametrMap 来定义自定义参数集或在调用远程服务期间执行其他操作.基本上在这里你说，如果我正在阅读、更新或删除(这是你的代码片段中值读取"的操作变量)，我想将以下参数添加到我在传输"中定义的方法中.
You should use parametrMap to define custom set of parameters or perform additional operations during the call to remote service. Basically here you saying, if I am reading, updating or deleting (this is the operation variable of value "read" in your snippet) I want to add following parameter(s) to the methods I defined in "transport".
在您的情况下，您没有定义 options.models，所以看起来，这意味着您的数据源没有任何变量/集合模型.那么它没有必要.在我看来，您尝试调用的 read 方法实际上并不需要任何参数，因此您可能只从 paramMap 返回空字符串，或者根本没有此配置部分.
In your case you didn't defined options.models so it seems, which means your datasource doesn't have any variable/collection models. Well it doesn't have to. To me it looks like the read method you trying to call doesn't really need any parameters so you might just return empty string from the paramMap or not to have this configuration section at all.
注意:您定义数据源的方式有点混乱，您在定义url"时不应提供配置数据"，例如.您正在获取网址的数据.请参阅本地与远程.
NOTE: the way you defined the datasource is bit confusing, you should not provide the configuration "data" when you defined the "url", eg. you are getting the data of the url. See Local vs Remote.
