您能告诉我如何从json对象中删除所有null和空字符串值吗？删除密钥时出现错误。
到目前为止，这是我所拥有的，但是不能正常工作：
$.each(sjonObj, function(key, value) { if(value == "" || value == null) { delete 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, "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" } ] }; $.each(sjonObj, function(key, value) { if(value == "" || value == null) { delete sjonObj.key; } }); console.log(sjonObj); <script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script>
您sjonObj.key实际上是要删除。您需要使用数组访问符号：
sjonObj.key
delete sjonObj[key];
但是，这也将删除value等于0的地方，因为您没有使用严格的比较。使用===来代替：
===
$.each(sjonObj, function(key, value){ if (value === "" || value === null){ delete sjonObj[key]; } });
但是，这只会使对象浅走。要深入地做，可以使用递归：
(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); 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, "repeatCount": 0, "retryCount": 0, "totalRepeatCount": 0, "totalRetryCount": 0, "testCaseId": "b", "summaryReportRequired": "false", "postConditionExecution": "ON_SUCCESS" } ] }; (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 (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lodash / underscore.js之类的库，则可以_.pick改用。但是，由于两个库都没有提供深层过滤功能，因此您仍然需要使用递归进行深层过滤。
_.pick
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);
此变体具有保留原始对象不变的附加优点，但是它确实创建了一个全新的副本，如果您不需要原始对象，效率将会降低。
