easyui的treegrid实现树型向上汇总功能

var treeList = jQuery(‘#treegrid‘).treegrid(‘getChildren‘);
var treeListOnlyTopNodes = [];
for (var i = 0; i < treeList.length; i++) {
    if (!treeList[i].pid) {
　　　　treeListOnlyTopNodes.push(treeList[i]);
    }
}
treeSum(treeListOnlyTopNodes);

function treeSum(treeList) {
    // console.log(treeList);
    for (var i = 0; i < treeList.length; i++) {
        sumMoneyToItsParent(treeList[i]);
    }
}

function sumMoneyToItsParent(item) {
    let sumMoney = 0;
    if (item.children && item.children.length) {
        for (let childItem of item.children) {
            sumMoneyToItsParent(childItem);
            sumMoney = (Number(sumMoney) + Number(childItem.comeMoney || 0)).toFixed(2);
        }
        item.comeMoney = sumMoney;
        jQuery(‘#treegrid‘).treegrid(‘refresh‘, item.id);
    }
}
