對(duì)于JSON字符串的操作。移除鍵值、添加屬性。
//刪除JSON對(duì)象value值var json=[.....];delete(json['key']);或者delete(json.key);//添加對(duì)象objectjson.object=value;或者json['object']=value;
如果數(shù)據(jù)是查詢數(shù)據(jù)庫得到的，那么可能會(huì)存在空值，for循環(huán)JSON數(shù)據(jù)挨個(gè)移除空值或者操作數(shù)據(jù)比較繁瑣。
這時(shí)候可以使用for…in來循環(huán)屬性 去除空值或者操作數(shù)據(jù)。
function removeEmptyObject(object){ for (var i in object) { var value = object[i]; if (typeof value === 'object') { if (Array.isArray(value)) { if (value.length == 0) { delete object[i]; continue; } } removeEmptyObject(value); //按需添加 if (isEmpty(value)) { delete object[i]; } } else { if (value === '' || value === null || value === undefined) { delete object[i]; } else { } } } return object;}//是否為空function isEmpty(object) { for (var name in object) { return false; } return true;}操作組織架構(gòu)JSON數(shù)據(jù)，移除空鍵值，子集內(nèi)容合并到新鍵children下。
function removeEmptyObject(object){ for (var i in object) { var value = object[i]; if (typeof value === 'object') { if (Array.isArray(value)) { if (value.length == 0) { //alert(object[i]); delete object[i]; continue; }else{ var a=[]; if(i=='jobChildren'){ for (var j = 0; j < object[i].length; j++) { a.push(object[i][j]); } delete object[i]; }else if(i=='userChildren'){ for (var j = 0; j < object[i].length; j++) { a.push(object[i][j]); } delete object[i]; }else if(i=='deptChildren'){ for (var j = 0; j < object[i].length; j++) { a.push(object[i][j]); } delete object[i]; }else if(i=='companyChildren'){ for (var j = 0; j < object[i].length; j++) { a.push(object[i][j]); } delete object[i]; }else if(i=='jobDeptChildren'){ for (var j = 0; j < object[i].length; j++) { a.push(object[i][j]); } delete object[i]; } if(a.length>0&&object["children"]!=undefined){ for (var k = 0; k < object["children"].length; k++) { a.push(object["children"][k]); } object["children"]=a; }else if(a.length>0 && object["children"]==undefined){ object["children"]=a; } } } removeEmptyObject(value); if (isEmpty(value)) { delete object[i]; } } else { if (value === '' || value === null || value === undefined) { delete object[i]; } else { } } } } function isEmpty(object) { for (var name in object) { return false; } return true; }需要的就試試吧。
