Question

我们如何从QueryString获取一个参数然后将其应用于JSON对象。我有以下JS文件，我想基于查询字符串快速更新dashboard-metrics-target元素。“target” ：“sumSeries（SERVER1.metric）”必须使用给定模板在运行时更改为SERVER2.metric。

ex .. http://testdashabord.com/sla-network.incoming.bytes-2013.11.02/logs/test&server=192.168.1.103必须获取“192.168.1.103”

的指标

var graphite_url = "demo";  // enter your graphite url, e.g. http://your.graphite.com

var dashboards = 
[
  { "name": "Users",  // give your dashboard a name (required!)
    "refresh": 5000,  // each dashboard has its own refresh interval (in ms)
                ,
    "metrics":  // metrics is an array of charts on the dashboard
    [
      {
        "alias": "signups",  // display name for this metric
        "target": "sumSeries(SERVER1.metric)",  // enter your graphite barebone target expression here
        "description": "New signups to the website",  // enter your metric description here
        "summary": "sum",  // available options: [sum|min|max|avg|last|<function>]
        "summary_formatter": d3.format(",f"), // customize your summary format function. see d3 formatting docs for more options
      },
      {
        "alias": "signup breakdown",
        "target": "sumSeries(stats.*.event)",  // target can use any graphite-supported wildcards
        "description": "signup breakdown based on site location",
        "renderer": "area",  // use any rickshaw-supported renderer
        "unstack": true  // other parameters like unstack, interpolation, stroke are also available (see rickshaw documentation for more info)
        "colspan": 3  // the graph can span across 1,2 or 3 columns
      },

  ]
  }, ...

我的方法： ..1。从URL

获取参数

var first = getUrlVars()["server"];

function getUrlVars() {
    var vars = {};
    var parts = window.location.href.replace(/[?&]+([^=&]+)=([^&]*)/gi, function(m,key,value) {
        vars[key] = value;
    });
    return vars;
}

.. 2。更新数组的元素。

如果建议采用更好的方法，我将感激不尽。
