同名相邻节点合并

链路精简

// 链路精简，把时间在contact后面的节点放到contact的node节点里
var temp = [];
for (var k = 0; k < arrTrance.length; k++) {
     if (arrTrance[k].name == "contact") {
         var moduleContact = arrTrance[k];
         var sameData = [];
         // 嵌套循环判断后续节点,如非contact节点时,数据放入临时数组B.同时外层循环游标+1;如为人工节点时,跳出嵌套循环
         for (var h = k + 1; h < arrTrance.length; h++) {
             if (arrTrance[h].name != "contact") {
                 sameData.push(arrTrance[h]);
                 k++
             } else {
                 break;
             }
         }
         // 将临时合并数组 放入原数组的合并节点
         moduleContact.node = sameData;
         temp.push(moduleContact)
     } else {
         temp.push(arrTrance[k]);
     }
