使用d3.json如何从这种格式转换
[{" HANDLERID":" AET55V8366"," HANDLER_MODEL":" AETRIUM 55V8", " START1":" 2014-03-30 00:00:00"," END1":" 2014-06-17 02:44:11& #34;" VAL1":" 49.7950&#34 ;, " START2":" 2014-06-17 02:44:11"," END2":" 2014-07-18 18:13:51& #34;" VAL2":" 69.7130&#34 ;, " START3":" 2014-07-18 18:13:51"," END3":" 2014-09-04 05:28:22& #34;" VAL3":" 99.00"},

这种格式???????????

var my=[];
d3.json("data.json", function(data){ data.forEach(function(d){ my.push(d);}); });
var result=[];
my.forEach(function(d, i){
result.push({"startDate": (d3.time.format("%Y-%m-%d %X").parse(my[i].START1)),
"endDate": (d3.time.format("%Y-%m-%d %X").parse(my[i].END1)),
"taskName": my[i].HANDLERID,
"status": my[i].VAL1});
result.push({"startDate": (d3.time.format("%Y-%m-%d %X").parse(my[i].START2)),

console.log(result);
结果数组是您要查找的数组。 希望它能帮到你。
data.json是包含问题和观察结果数组中上述数据格式的文件。

目前还不清楚你想在这做什么。我可以看到你想要提取开始和结束日期和时间,但有3个选择,所以我只选择1.此外,你应该知道你不能在json对象中创建新的日期对象。您需要在外部执行此操作并将其传递到对象中。
无论如何,你应该能够使用下面的代码实现你的目标(这与saikiran发布的概念类似,只是更紧凑一些(而且我懒得解析三者中的每一个)时间对象)。
d3.json("rawJson.json", function (error, json){
console.log(json)
var newJson = [];
var timeFormat = d3.time.format("%Y-%m-%d %H:%M:%S");
json.forEach(function (d,i) {
el = {
"startDate": timeFormat.parse(d.START1),
"endDate": timeFormat.parse(d.END1),
"taskName": d.HANDLERID,
"status": d.VAL1
}
newJson.push(el)
})
console.log(newJson);
})
最后一件事,你发布的json很难读。我建议使用像jsonlint这样的linter服务。它使你的json更具人性化,并检查结构错误。
