Can I divide an array or string into multiple variables?

Here's where I've been:

I made a PHP client call via soap to retrieve an array of data,

I successfully receieved and converted my array to JSON via json_encode,

I then echoed it back to my page.

Here's where I am:

I get back my array in this format...

{"MethodName":"ID,11|1|Item1,22|2|Item2,33|3|Item3"}

Here's wher开发者_高级运维e I want to be:

Using Javascript or JSON, my objective is to end up with 2 variables (Method & ID) and one variable array (ItemList)...ie

• var Method = "MethodName";
• var ID = "ID";
• var ItemList = ['11|1|Item1' , '22|2|Item2' , '33|3|Item3'];

I have the front and back of my script working, but I'm stumped on the array(string)...

How do I parse, divide, or split this result?

You would make this much simpler on yourself if you had it as a mixed array in php before you called json_encode (so that instead of a string, each item would be it's own JSON object).

Example:

$arr = array();
$itemList = array();
$itemList[1] = "11|1";
$itemList[2] = "22|2";
$itemList[3] = "33|3";

$arr['Method']="MethodName";
$arr['ID']= "ID";
$arr['itemList'] = $itemList;

$output = json_encode($arr);

This results in $output having the following JSON:

{"Method":"MethodName","ID":"ID","itemList":{"1":"11|1","2":"22|2","3":"33|3"}}

Which you can then easily pull out, as the itemList is an array in JSON already.

i'd probably try a regex first thing. something like

var match = data.match(/\{"(.+)"\:"([^,]+),(.+)"\}/);

the parentheses will separate the matches. match[0] will be the whole thing, match[1] will be the method name, match[2] will be the id, match[3] will be the remainder as a string. you can then do

var itemList = match[3].split(',');

to get the array for the 3rd part.

Let's say your intial array is initial_array with value {"MethodName":"ID,11|1|Item1,22|2|Item2,33|3|Item3"}

for (key in initial_array) {  
  Method = key;                     // Method = "MethodName"
  break;
}
myvalue = initial_array[Method];
myarray = myvalue.split(",");      // myarray = ["ID","11|1|Item1",...]
ID = myarray[0];                   // ID = "ID"
ItemList = myarray.splice(1);      // ItemList = ["11|1|Item1","22|2|Item2",...] 

Here you go:

var myobject = {"MethodName":"ID,11|1|Item1,22|2|Item2,33|3|Item3"};
var itemlist = [];
var method;
var ID;

for (key in myobject) { 
    method = key;
    break;
}

itemlist = myobject[method].split(',');
ID = itemlist.shift();

Here is a JSFiddle for you to run.
