json数据的Javascript数据结构

Question

嗨，我有一些来自 Jenkins 的 JSON 数据。我获取 JSON 并获取如下所示的作业对象:

{
     color: "#FF4136"
     name: "XXX-tomcat-accept"
     url: "http://1.1.7.9:8080/job/xxx-tomcat-verify/"
}

每个作业流都有三个作业

• -验证
• -接受
• -交付

我想做的是构建一个数据结构，它是数组的数组或数组的哈希，其中第一个元素是验证，然后接受，然后交付(与上面的列表相同的顺序)。

所以像这样

0[xxx-tomcat-verify,xxx-tomcat-accept,xxx-tomcat-delivery]
1[xxx-linux-verify,xxx-linux-accept,xxx-linux-delivery]
2
3
......

我只是无法理解在上述结构中重新组装数据的逻辑。我想做的是使用 d3 为 Jenkins 构建一个轻量级构建仪表板。以下代码构建作业并为其添加标签。只需要按照正确的顺序排列它们即可。

我的代码是

d3.json("data.json", function(error, data) {

    job.forEach(function(d){

        //green balls !
        if (d.color === "blue") {
            d.color = "#2ECC40";
        }   else if(d.color === "notbuilt"){
            d.color = "#AAAAAA";

        } else if(d.color === "aborted"){
            d.color = "#0074D9";
        } else if(d.color === "red"){
            d.color = "#FF4136"

        }


        var svgContainer = d3.select("body").append("svg")
                            .attr("width", 460)
                            .attr("height", 110);

        var rectangle = svgContainer.append("rect")
                            .attr("x", 5)
                            .attr("y", 5)
                            .attr("width", 450)
                            .attr("height", 100)
                            .attr("text", d.name)
                            .attr("rx", 10)
                            .attr("ry", 10)
                            .attr("xlink:href", d.url)
                            .attr("fill", d.color);

        var text = svgContainer.selectAll("text")
                        .data(rectangle)
                        .enter()
                        .append("text");

        var textLabels = text
                 .attr("x", 20)
                 .attr("y", 60)
                 .text(d.name)
                 .attr("font-family", "Avro")
                 .attr("font-size", "30px")
                 .attr("fill", "#2f2f2f");



        });

});

您可以使用 d3.nest()。

https://jsfiddle.net/ermineia/jz293y70/1/

var jobs = [{
     color: "#FF4136",
     name: "XXX-tomcat-verify",
     url: "http://1.1.7.9:8080/job/xxx-tomcat-verify/"
},
{
     color: "#FF4136",
     name: "XXX-tomcat-accept",
     url: "http://1.1.7.9:8080/job/xxx-tomcat-accept/"
},
{
     color: "#FF4136",
     name: "XXX-tomcat-delivery",
     url: "http://1.1.7.9:8080/job/xxx-tomcat-delivery/"
},
{
     color: "#FF4136",
     name: "XXX-linux-verify",
     url: "http://1.1.7.9:8080/job/xxx-tomcat-verify/"
},
{
     color: "#FF4136",
     name: "XXX-linux-accept",
     url: "http://1.1.7.9:8080/job/xxx-tomcat-accept/"
},
{
     color: "#FF4136",
     name: "XXX-linux-delivery",
     url: "http://1.1.7.9:8080/job/xxx-tomcat-delivery/"
}];

console.log( jobs );
var formatted_map = d3.nest().key( function( d ) { return d.name.substr( 0, d.name.lastIndexOf( '-' ) ); } ).map( jobs );
console.log( formatted_map );
console.log( JSON.stringify( formatted_map ))
var formatted_array = d3.nest().key( function( d ) { return d.name.substr( 0, d.name.lastIndexOf( '-' ) ); } ).entries( jobs );
console.log( formatted_array );
console.log( JSON.stringify( formatted_array ))
