用于Javascript（JQuery）将数组处理为摘要数据的最佳算法

我有（n）JSON编码的技能组对象，我需要能够派生出有意义的摘要信息以供显示，按组，类别，资源分组能力。考虑到我已经必须解析DOM去除数据，处理这些数据以减少客户端影响的最佳方式是什么？用于Javascript（JQuery）将数组处理为摘要数据的最佳算法

N.B.数据集不超过5000条记录。

例如

@{"resource" : "","group" : "Technologies","category" : "Extract Transform Load","skill" : "Informatica Powercenter","capabilityWeighting" : 1} 
@{"resource" : "","group" : "Technologies","category" : "Extract Transform Load","skill" : "IBM Datastage","capabilityWeighting" : 0} 
@{"resource" : "","group" : "Technologies","category" : "Extract Transform Load","skill" : "Microsoft SSIS","capabilityWeighting" : 4} 
@{"resource" : "","group" : "Technologies","category" : "Extract Transform Load","skill" : "Ab Initio","capabilityWeighting" : 15} 
@{"resource" : "","group" : "Technologies","category" : "Extract Transform Load","skill" : "Informatica Powercenter","capabilityWeighting" : 4} 
@{"resource" : "","group" : "Technologies","category" : "Extract Transform Load","skill" : "IBM Datastage","capabilityWeighting" : 15} 
@{"resource" : "","group" : "Technologies","category" : "Extract Transform Load","skill" : "Microsoft SSIS","capabilityWeighting" : 1}

总结于： -

对于提取转换负载具有40能力加权：

Infomatica的PowerCenter能力加权= 5
IBM的DataStage能力加权= 15
微型软SSIS能力加权= 5
从头算能力加权= 15

或： -

对于资源X在n = X + Y + Z的能力加权

技术：提取变换负载能力权重= x
种技术：商业智能能力权重= Y
技术：数据仓库性能权重= Z

如果你想这样做，在客户端，我只想用简单的哈希表（字典），以计算摘要。

，你可以通过你的ňJSON编码的对象，保持流水账摘要对象循环：

var data = [ 
    {"resource": "", "group": "Technologies", "category": "Extract Transform Load", "skill": "Informatica Powercenter", "capabilityWeighting": 1}, 
    {"resource": "", "group": "Technologies", "category": "Extract Transform Load", "skill": "IBM Datastage", "capabilityWeighting": 0}, 
    {"resource": "", "group": "Technologies", "category": "Extract Transform Load", "skill": "Microsoft SSIS", "capabilityWeighting": 4}, 
    {"resource": "", "group": "Technologies", "category": "Extract Transform Load", "skill": "Ab Initio", "capabilityWeighting": 15}, 
    {"resource": "", "group": "Technologies", "category": "Extract Transform Load", "skill": "Informatica Powercenter", "capabilityWeighting": 4}, 
    {"resource": "", "group": "Technologies", "category": "Extract Transform Load", "skill": "IBM Datastage", "capabilityWeighting": 15}, 
    {"resource": "", "group": "Technologies", "category": "Extract Transform Load", "skill": "Microsoft SSIS", "capabilityWeighting": 1} 
]; 

var summary = {}; 

for (var i = 0, c = data.length; i < c; i += 1) { 
    var row = data[i]; 
    if (!summary.hasOwnProperty(row.category)) summary[row.category] = { skills: {}, total: 0 }; 
    if (!summary[row.category].skills.hasOwnProperty(row.skill)) summary[row.category].skills[row.skill] = 0; 
    summary[row.category].skills[row.skill] += row.capabilityWeighting; 
    summary[row.category].total += row.capabilityWeighting; 
} 

// "summary" now has all the data summarized as you need. 
// You just need to loop through it and output using whatever phrasing you want.
