Question

我已经从javascript传递了一个字符串json对象到swift。

JS

'use strict';

var labdetail = function()
{
var labs = ["sdsdsd","suds","DH-sdsd","DH-sdsd"]
var labgrp = {labGrp:"R", labGrpDesc:"sdsd",labs:labs}
var labGroups = []
labGroups[0] = labgrp
var labs1 = ["dsdsd","suds","DH-sdsd","DH-dfdf]
var labgrp1 = {labGrp:"H", labGrpDesc:"dfdf",labs:labs}
labGroups[1] = labgrp1
return JSON.stringify(labGroups);

}

迅速

import UIKit
import JavaScriptCore
class ViewController: UIViewController {

override func viewDidLoad() {
    super.viewDidLoad()
    let context = JSContext()
    let returnLabResultJSPath = NSBundle.mainBundle().pathForResource("returnLabResult", ofType: "js")
    let contentData = NSFileManager.defaultManager().contentsAtPath(returnLabResultJSPath!)
    let content = NSString(data: contentData!, encoding: NSUTF8StringEncoding) as? String
   //     let returnresult = try String(contentsOfFile: returnLabResultJSPath!, encoding: NSUTF8StringEncoding)
    context.evaluateScript(content)
    let getlabfunction =  context.objectForKeyedSubscript("labdetail")
    var labresult = getlabfunction.callWithArguments([])
    let labresultdict :dictionary = labresult.toDictionary()

    print(labresult)

}

我想将其更改为原始结构。我尝试使用todictionary()但是失败了

现在实验结果的结果是 [{＆＃34; labGrp＆＃34;：＆＃34; R＆＃34;，＆＃34; labGrpDesc＆＃34;：＆＃34;伤心难过＆＃34;，＆＃34;实验室＆＃34;：[＆＃34;伤心难过＆＃34;，＆＃34; asdasd＆＃34;，＆＃34; sadsad-sadsa＆＃34;，＆＃34; DH-asdasd＆＃34;]}，{＆＃34; labGrp＆＃34 ;：＆＃34; H＆＃34;＆＃34; labGrpDesc＆＃34;：＆＃34;生物学＆＃34;＆＃34;实验室＆＃34;：[＆＃34; asdsad＆＃34;＆＃ 34; asdsad＆＃34;＆＃34;和＆＃34;＆＃34; DH-asdasd＆＃34;]}]

我希望它是一个数组，数组[0]包含{＆＃34; labGrp＆＃34;：＆＃34; R＆＃34;，＆＃34; labGrpDesc＆＃34;：＆＃34;悲伤悲伤＆＃34;，＃34;实验室＆＃34;：[＆＃34;伤心难过＆＃34;，＆＃34; asdasd＆＃34;，＆＃34; sadsad-sadsa＆＃34;，＆＃34; DH -asdasd＆＃34;]}

和数组[1]包含{＆＃34; labGrp＆＃34;：＆＃34; H＆＃34;，＆＃34; labGrpDesc＆＃34;：＆＃34;生物学＆＃34;，＆＃34;实验室＆＃34;：[＆＃34; asdsad＆＃34;＆＃34; asdsad＆＃34;＆＃34;和＆＃34;＆＃34; DH-asdasd＆＃34;]}

希望您需要反序列化JSon对象，然后它会生成Dictionary对象。

例如：

      var labresult = getlabfunction.callWithArguments([])

        do{
            if let data = labresult.dataUsingEncoding(NSUTF8StringEncoding) {
                let json = try NSJSONSerialization.JSONObjectWithData(data, options: NSJSONReadingOptions()) as? [String:String]
          }catch{  }

在swift中改回原来的json结构
