从属性中获取特定字段

Question

我是 JavaScript 和 Dynamics CRM 的新手。 我有以下代码：

var analysisCode = Xrm.Page.getAttribute("rf_analysiscode").getValue()[0].entityValues;

作为 analysisCode 的值，我得到以下输出：

{
    "rf_name":{"name":"rf_name","value":"ABC"},
    "rf_code":{"name":"rf_code","value":"ABC"},
    "createdon":{"name":"createdon","value":"24.1.2022 10.39"}
}

但我只想获取 rf_code。我如何检索它？

Answer 1

试试这个：

analysisCode = {
    "rf_name":{"name":"rf_name","value":"ABC"},
    "rf_code":{"name":"rf_code","value":"ABC"},
    "createdon":{"name":"createdon","value":"24.1.2022 10.39"}
};
let rf_code = analysisCode.rf_code;
console.log('rf_code : ', rf_code);
console.log('rf_code Value : ', rf_code.value);

如果您以字符串形式获取输出，首先需要解析输出，然后您可以从该 json 中获取任何值。

试试这个：

analysisCode = '{"rf_name":{"name":"rf_name","value":"ABC"},"rf_code":{"name":"rf_code","value":"ABC"},"createdon":{"name":"createdon","value":"24.1.2022 10.39"}}'
let rf_code = JSON.parse(analysisCode).rf_code;
console.log('rf_code : ', rf_code);
console.log('rf_code Value : ', rf_code.value);

Answer 2

将结果解析为 JSON，如下所示：

const analysisCodeObj = JSON.parse(analysisCode);

获取 rf_code，如下所示：

const rfCodeObj = analysisCodeObj["rf_code"];
