codeMirror中JSON 數據，定位某個屬性在第幾行,

json內容賦值到codeMirror編輯器中使用

第一種方法

var jsonObj = { "OrdererOrgs": [ { "Name": "orderer", "Domain": "example1.com", "Specs": [ { "Hostname": "orderer" } ] } ], "PeerOrgs": [ { "Name": "org1", "Domain": "org1.example1.com", "Specs": [ { "Hostname": "peer0" } ], "Users": { "Count": 1 } }, { "Name": "org2", "Domain": "org2.example2.com", "Specs": [ { "Hostname": "peer3" } ], "Users": { "Count": 1 } } ] }

editor.setValue(JSON.stringify(jsonObj, null, 4))

JSON.stringify()能讓json對象，格式化內容，將數據分成一行行

根據codeMirror.lineInfo(i).text 來循環出行內容對應行數

var prop = "OrdererOrgs[0]|Domain"  // 需要查找的屬性名格式

var lineTotal1 = jsonEditor1.lineCount(),
     arrObject1 = {}; 
     for(var i=0;i<lineTotal1;i++){          // 將每行數據對應行數
         arrObject1[i] = jsonEditor1.lineInfo(i).text
     }
var jsonString = JSON.stringify(arrObject1).replace(/\s+/g,"|")  // 轉爲好查詢的字符串
searchJsonPropertyLine(prop,jsonString)

根據codeMirror.getValue()  來循環出行內容對應行數

//var jsonData ={"OrdererOrgs":[{"Name":"orderer","Domain":"example1.com","Specs":[{"Hostname":"orderer"}]}],"PeerOrgs":[{"Name":"org1","Domain":"org1.example1.com","Specs":[{"Hostname":"peer0"}],"Users":{"Count":1}},{"Name":"org2","Domain":"org2.example2.com","Specs":[{"Hostname":"peer3"}],"Users":{"Count":1}}]}
//$("#content").val(JSON.stringify(jsonData,null,4))
// 註銷的內容，是無需codeMirror編輯器，只需textarea元素
var prop2 = "OrdererOrgs[0]|Name";
//var getJsonData2 = $("#content").val();
var getJsonData2 = jsonEditor1.getValue();
console.log(JSON.stringify(getJsonData2))

var jsonObjTest = JSON.stringify(getJsonData2).slice(1,JSON.stringify(getJsonData2).length-1).replace(/\\n/g,"|").split("|"),
	jsonObjTestLen = jsonObjTest.length;

var i=0,
    jsonReintegration = {};
	
for(i;i<jsonObjTestLen;i++){
	jsonReintegration[i] = jsonObjTest[i]
}

var sdTest = JSON.stringify(jsonReintegration).replace(/\\\\/g,"").replace(/\s+/g,"|")

searchJsonPropertyLine(prop2,sdTest)

searchJsonPropertyLine 函數js

function searchJsonPropertyLine(prop,lineToTextObject){   // 查找JSON的屬性行數

    var getPropertyString = prop

    // var getPropertyString = "PeerOrgs"
    var propArr = getPropertyString.split("|")
    var indexI = 0;
    var objectKey,
        objReg = /\[\d+\]/;

      if(numCheck){   // 有下標,例如[0]
