按对象值渗透JSON响应

时间：2018-06-11 05:43:43

标签： javascript json

我从服务器收到以下java响应，我的要求是显示servlet详细信息。

JSON

我已经编写了以下Javacript代码段，以便通过这些值渗透if(dataStoreLogFileSize > 10 && "dataStoreLogLevel": "production".) 但是它无法正常工作。任何人都可以帮我这个。

JSON

您正在过滤错误的数组，dataStoreLogLevel和dataStoreLogFileSize的数组位于data['web-app'][0]['servlet']['init-param']，因此您需要在.filter上应用data['web-app'].servlet阵列。

对于fileSize，您需要使用parseFloat来提取大小，因为它是一个字符串。

您需要修复.filter语法。

并使用,至console.log结果：

const data = {
    "web-app": {
        "servlet": [{
                "servlet-name": "cofaxCDS",

您可以使用此代码获取大于1gb的dataStoreLogFileSize和生成dataStoreLogLevel。
