问题描述

你能告诉我如何从json对象中删除所有null和空字符串值吗？我在删除密钥时收到错误。



这是我到目前为止所做的，但它无法正常工作：

  $。each（sjonObj，function（key，value）{
 if（value ==|| value == null）{
删除sjonObj.key; 
} 
}）; 
  

  var sjonObj = {executionMode：SEQUENTIAL ，coreTEEVersion：3.3.1.4_RC8，testSuiteId：yyy，testSuiteFormatVersion：1.0.0.0，testStatus：IDLE，reportPath：，startTime： 0，durationBetweenTestCases：20，endTime：0，lastExecutedTestCaseId：0，repeatCount：0，retryCount：0，fixedTimeSyncSupported：false，totalRepeatCount：0，totalRetryCount：0， summaryReportRequired：true，postConditionExecution：ON_SUCCESS，testCaseList：[{executionMode：SEQUENTIAL，commandList：[]，testCaseList：[]，testStatus：IDLE ，boundTimeDurationForExecution：0，startTime：0，endTime：0，label：null，repeatCount：0，retryCount：0，totalRepea tCount：0，totalRetryCount：0，testCaseId：a，summaryReportRequired：false，postConditionExecution：ON_SUCCESS}，{executionMode：SEQUENTIAL，commandList：[ ]，testCaseList：[{executionMode：SEQUENTIAL，commandList：[{commandParameters：{serverAddress：www.ggp.com，echoRequestCount：，sendPacketSize： ，interval：，ttl：，addFullDataInReport：True，maxRTT：，failOnTargetHostUnreachable：True，failOnTargetHostUnreachableCount：，initialDelay ：，commandTimeout：，testDuration：}，commandName：Ping，testStatus：IDLE，label：，reportFileName：tc_2-tc _1-cmd_1_Ping，endTime：0，startTime：0，repeatCount：0，retryCount：0，totalRepeatCount：0，totalRetryCount：0，postConditionExecution：ON_SUCCESS， detailReportRequired：true，summaryReportRequired：true}]，testCaseList：[]，testStatus：IDLE，boundTimeDurationForExecution：0，startTime：0，endTime：0， label：null，repeatCount：0，retryCount：0，totalRepeatCount：0，totalRetryCount：0，testCaseId：dd，summaryReportRequired：false，postConditionExecution： ON_SUCCESS}]，testStatus：IDLE，boundTimeDurationForExecution：0，startTime：0，endTime：0，label：null，repeatCount：0，retryCount：0，totalRepeatCount：0，totalRetryCount：0，testCaseId：b，summaryReportRequired：false，postConditionExecution：ON_SUCCESS}]}; $。each（sjonObj，function（key，value） ）{if（value ==|| value == null）{delete sjonObj.key; };）; console.log（sjonObj）;

解决方案

您要删除 sjonObj.key ，字面意思。您需要使用数组访问表示法：

  delete sjonObj [key];

然而，这也会删除值等于0的地方，因为你没有使用严格的比较。改为使用 === ：

  $。each（sjonObj，function （键，值）{
 if（value ===|| value === null）{
 delete sjonObj [key]; 
} 
}）;

但是，这只会使对象浅浅。要做得很深，你可以使用递归：

 （函数过滤器（obj）{
 $ .each（obj） ，function（key，value）{
 if（value ===|| value === null）{
 delete obj [key]; 
} else if（Object.prototype） .toString.call（value）==='[object Object]'）{
 filter（value）; 
} else if（$ .isArray（value））{
 $ .each （value，function（k，v）{filter（v）;}）; 
} 
}）; 
}）（sjonObj）; 
  

  var sjonObj = {executionMode：SEQUENTIAL，coreTEEVersion：3.3.1.4_RC8，testSuiteId：yyy，testSuiteFormatVersion：1.0.0.0，testStatus： IDLE，reportPath：，startTime：0，durationBetweenTestCases：20，endTime：0，lastExecutedTestCaseId：0，repeatCount：0，retryCount：0，fixedTimeSyncSupported： false，totalRepeatCount：0，totalRetryCount：0，summaryReportRequired：true，postConditionExecution：ON_SUCCESS，testCaseList：[{executionMode：SEQUENTIAL，commandList：[] ，testCaseList：[]，testStatus：IDLE，boundTimeDurationForExecution：0，startTime：0，endTime：0，label：null，repeatCount： 0，retryCount：0，totalRepeatCount：0，totalRetryCount：0，testCaseId：a，summaryReportRequired：false，postConditionExecution：ON_SUCCESS}，{executionMode： SEQUENTIAL，commandList：[]，testCaseList：[{executionMode：SEQUENTIAL，commandList：[{commandParameters：{serverAddress：www.ggp.com，echoRequestCount ：，sendPacketSize：，interval：，ttl：，addFullDataInReport：True，maxRTT：，failOnTargetHostUnreachable：True， failOnTargetHostUnreachableCount：，initialDelay：，commandTimeout：，testDuration：}，commandName：Ping，testStatus：IDLE，label： ，reportFileName：tc_2-tc_1-cmd_1_Ping，endTime：0，startTime：0，repeatCount：0，retryCount：0，totalRepeatCount：0，totalRetryCount：0， postConditionExecution：ON_SUCCESS，detailReportRequired：true，summaryReportRequired：true}]，testCaseList：[]，testStatus：IDLE，boundTimeDurationForExecution：0，startTime： 0，endTime：0，label：null，repeatCount：0，retryCount：0，totalRepeatCount：0，totalRetryCount：0，testCaseId：dd，summaryReportRequired： false，postConditionExecution：ON_SUCCESS}]，testStatus：IDLE，boundTimeDurationForExecution：0，startTime：0，endTime：0，label：null，r epeatCount：0，retryCount：0，totalRepeatCount：0，totalRetryCount：0，testCaseId：b，summaryReportRequired：false，postConditionExecution：ON_SUCCESS}]}; （函数filter（obj）{$ .each（obj，function（key，value）{if（value ===|| value === null）{delete obj [key]; } else if（Object.prototype.toString.call（value）==='[object Object]'）{filter（value）; } else if（Array.isArray（value））{value.forEach（function（el）{filter（el）;}）; }}）;}}（sjonObj）; console.log（sjonObj） 

 < script src =https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js>< / script>





请注意，如果您愿意使用像lodash / underscore.js这样的库，你可以使用 _。选择。但是，您仍然需要使用递归来深度过滤，因为两个库都没有提供深度过滤功能。

  sjonObj =（function filter（obj）{
 var filtered = _.pick（obj，function（v）{return v！==''&& v！== null;}）; 
 return _。 cloneDeep（filtered，function（v）{return v！== filtered&& _.isPlainObject（v）？filter（v）：undefined;}）; 
}）（sjonObj）;

此变体具有保持原始对象不被修改的附加优势，但它确实创建了一个全新的副本，如果你不需要原始对象，效率会降低。



  var sjonObj = {executionMode：SEQUENTIAL，coreTEEVersion：3.3.1.4_RC8，testSuiteId：yyy，testSuiteFormatVersion：1.0.0.0，testStatus ：IDLE，reportPath：，startTime：0，durationBetweenTestCases：20，endTime：0，lastExecutedTestCaseId：0，repeatCount：0，retryCount：0，fixedTimeSyncSupported ：false，totalRepeatCount：0，totalRetryCount：0，summaryReportRequired：true，postConditionExecution：ON_SUCCESS，testCaseList：[{executionMode：SEQUENTIAL，commandLi st：[]，testCaseList：[]，testStatus：IDLE，boundTimeDurationForExecution：0，startTime：0，endTime：0，label：null，repeatCount：0 ，retryCount：0，totalRepeatCount：0，totalRetryCount：0，testCaseId：a，summaryReportRequired：false，postConditionExecution：ON_SUCCESS}，{executionMode： SEQUENTIAL，commandList：[]，testCaseList：[{executionMode：SEQUENTIAL，commandList：[{commandParameters：{serverAddress：www.ggp.com，echoRequestCount ：，sendPacketSize：，interval：，ttl：，addFullDataInReport：True，maxRTT：，failOnTargetHostUnreachable：True，failOnTargetHostUnreachableCount ：， initialDelay：，commandTimeout：，testDuration：}，commandName：Ping，testStatus：IDLE，label：，reportFileName： tc_2-tc_1-cmd_1_Ping，endTime：0，startTime：0，repeatCount：0，retryCount：0，totalRepeatCount：0，totalRetryCount：0，postConditionExecution：ON_SUCCESS ，detailReportRequired：true，summaryReportRequired：true}]，testCaseList：[]，testStatus：IDLE，boundTimeDurationForExecution：0，startTime：0，endTime： 0，label：null，repeatCount：0，retryCount：0，totalRepeatCount：0，totalRetryCount：0，testCaseId：dd，summaryReportRequired： false，postConditionExecution：ON_SUCCESS}]，testStatus：IDLE，boundTimeDurationForExecution：0，startTime：0，endTime：0，label：null，repeatCount： 0，retryCount：0，totalRepeatCount：0，totalRetryCount：0，testCaseId：b，summaryReportRequired：false，postConditionExecution：ON_SUCCESS}]}; sjonObj =（函数过滤器（obj）{var filtered = _.pick（obj，function（v）{return v！==''&& v！== null; }）; return _.cloneDeep（filtered，function（v）{return v！== filtered&& _.isPlainObject（v）？filter（v）：undefined;}）;}}（sjonObj）; console.log（sjonObj ）;

Can you please tell me how to remove all null and empty string values from a json object? I am getting an error while deleting the key.

解决方案

You're deleting sjonObj.key, literally. You need to use array access notation:

delete sjonObj[key];

However, that will also delete where value is equal to 0, since you're not using strict comparison. Use === instead:

$.each(sjonObj, function(key, value){
    if (value === "" || value === null){
        delete sjonObj[key];
    }
});

However, this will only walk the object shallowly. To do it deeply, you can use recursion:

(function filter(obj) {
    $.each(obj, function(key, value){
        if (value === "" || value === null){
            delete obj[key];
        } else if (Object.prototype.toString.call(value) === '[object Object]') {
            filter(value);
        } else if ($.isArray(value)) {
            $.each(value, function (k,v) { filter(v); });
        }
    });
})(sjonObj);

Note that if you're willing to use a library like lodash/underscore.js, you can use _.pick instead. However, you will still need to use recursion to filter deeply, since neither library provides a deep filter function.

sjonObj = (function filter(obj) {
    var filtered = _.pick(obj, function (v) { return v !== '' && v !== null; });
    return _.cloneDeep(filtered, function (v) { return v !== filtered && _.isPlainObject(v) ? filter(v) : undefined; });
})(sjonObj);

This variant has the added advantage of leaving the original object unmodified, but it does create an entirely new copy, which would be less efficient if you don't need the original object.
