只需用

  d3.json  c> json = JSON.parse（myjson）; 

IE：

  var myjson ='{name：flare，children：[{name：analytics，children：[{ name：cluster，children：[{name：MergeEdge，size：10}]}]}]}'; 

 // d3.json /path/flare.json，function（json）{#delete this line 

 json = JSON.parse（myjson）; //添加此行

 //渲染逻辑

 //}＃删除此行
 

UPDATE 09/2013

原始程式码已变更。因此varname json 应为 root ：

  // d3.json（flare.json，function（error，root）{#delete this line 

 root = JSON.parse（myjson）; // add this line 

 //渲染逻辑

 //}＃删除此行
 

I am learning d3. There are certain ways of loading the data in d3 js. But all of them seem to make a HTTP GET. In my scenario, I already have the json data in a string. How can I use this string instead of making another http request? I tried to look for documentation for this but found none.

This works:

d3.json("/path/flare.json", function(json) {
    //rendering logic here
}

Now, if I have:

//assume this json comes from a server (on SAME DOMAIN)
var myjson = '{"name": "flare","children": [{"name": "analytics","children": [{"name": "cluster","children": [{"name": "MergeEdge", "size": 10 }]}]}]}'; 

How do I use already computed 'myjson' in d3 & avoid a async call to server? Thanks.

Simply replace d3.json call with

json = JSON.parse( myjson );

IE:

var myjson = '{"name": "flare","children": [{"name": "analytics","children": [{"name": "cluster","children": [{"name": "MergeEdge", "size": 10 }]}]}]}';

// d3.json("/path/flare.json", function(json) { #delete this line

    json = JSON.parse( myjson ); //add this line

    //rendering logic here

//} #delete this line

UPDATE 09/2013

Original code has changed. So varname json should be root:

// d3.json("flare.json", function(error, root) { #delete this line

    root = JSON.parse( myjson ); //add this line

    //rendering logic here

//} #delete this line
