href可以傳集合(list)？用location.href可以

您好，這個(gè)應(yīng)該是可以的！

Vector、ArrayList、List使用方法有哪些？

??get(“two”);

System。out。println(“two = ” + n);

由于作為key的對(duì)象將通過(guò)計(jì)算其散列函數(shù)來(lái)確定與之對(duì)應(yīng)的value的位置，因此任何作為key的對(duì)象都必須實(shí)現(xiàn)hashCode和equals方法。hashCode和equals方法繼承自根類(lèi)Object，如果你用自定義的類(lèi)當(dāng)作key的話，要相當(dāng)小心，按照散列函數(shù)的定義，如果兩個(gè)對(duì)象相同，即obj1。

JSON對(duì)象轉(zhuǎn)換成List c#

using System.Web.Script.Serialization;

JavaScriptSerializer js = new JavaScriptSerializer();

List team = js.Deserialize >(jsonstr);

myobj是自己定義的一個(gè)和json匹配的類(lèi)，否則就用object，轉(zhuǎn)換后是一個(gè)dictory的list，設(shè)置斷點(diǎn)調(diào)試一下就可以看到內(nèi)容public class model

{

public int count { set; get; }

public list data { set; get; }

}

public class data

{

public string carlengthwin { set; get; }

public string caraxlerequire { set; get; }

public string tradetelephonenumber { set; get; }

}

然后使用javascriptserializer的deserialize方法反序列化，參數(shù)是json

記得采納哦！這是一個(gè)互轉(zhuǎn)的代碼，

json字符串怎么轉(zhuǎn)化為list

import java.util.HashMap;

import java.util.Map;

import net.sf.json.JSONObject;

public class Test {

public static void main(String[] args) {

String json = "{\"name\":\"reiz\"}";

JSONObject jsonObj = JSONObject.fromObject(json);

String name = jsonObj.getString("name");

jsonObj.put("initial", name.substring(0, 1).toUpperCase());

String[] likes = new String[] { "JavaScript", "Skiing", "Apple Pie" };

jsonObj.put("likes", likes);

Map ingredients = new HashMap ();

ingredients.put("apples", "3kg");

ingredients.put("sugar", "1kg");

ingredients.put("pastry", "2.4kg");

ingredients.put("bestEaten", "outdoors");

jsonObj.put("ingredients",ingredients);

System.out.println(jsonObj);

//這是使用org.json的程序：

import java.util.HashMap;

import java.util.Map;

import org.json.JSONException;

import org.json.JSONObject;

public class Test {

public static void main(String[] args) throws JSONException {

String json = "{\"name\":\"reiz\"}";

JSONObject jsonObj = new JSONObject(json);

String name = jsonObj.getString("name");

jsonObj.put("initial", name.substring(0, 1).toUpperCase());

String[] likes = new String[] { "JavaScript", "Skiing", "Apple Pie" };

jsonObj.put("likes", likes);

Map ingredients = new HashMap ();

ingredients.put("apples", "3kg");

ingredients.put("sugar", "1kg");

ingredients.put("pastry", "2.4kg");

ingredients.put("bestEaten", "outdoors");

jsonObj.put("ingredients", ingredients);

System.out.println(jsonObj);

System.out.println(jsonObj);

//兩者的使用幾乎是相同的，但org.json比json-lib要輕量得多，前者沒(méi)有任何依賴(lài)，而后者要依賴(lài)ezmorph和commons的lang、logging、beanutils、collections等//組件。將json字符串轉(zhuǎn)成java的array數(shù)組

private string json = "{\"address\":\"chian\",\"birthday\":{\"birthday\":\"2010-11-22\"},"+

"\"email\":\"email@123.com\",\"id\":22,\"name\":\"tom\"}";

@test

public void readjson2array() {

try {

json = "[" + json + "]";

jsonarray = jsonarray.fromobject(json);

object[] os = jsonarray.toarray();

system.out.println(os.length);

student[] stus = (student[]) jsonarray.toarray(jsonarray, student.class);

system.out.println(stus.length);

system.out.println(stus[0]);

} catch (exception e) {

e.printstacktrace();文章來(lái)源地址http://www.zghlxwxcb.cn/news/detail-400299.html

運(yùn)行的結(jié)果如下：

==============json arry string >>> java array ==================

#%%%{"address":"chian","birthday":{"birthday":"2010-11-22"},"email":"email@123.com","id":22,"name":"tom"}

{"address":"chian","birthday":{"birthday":"2010-11-22"},"email":"email@123.com","id":22,"name":"tom"}

{"address":"chian","birthday":{"birthday":"2010-11-22"},"email":"email@123.com","id":22,"name":"tom"}

將json字符串轉(zhuǎn)成java的list集合

private string json = "{\"address\":\"chian\",\"birthday\":{\"birthday\":\"2010-11-22\"},"+

"\"email\":\"email@123.com\",\"id\":22,\"name\":\"tom\"}";

public void readjson2list() {

try {

json = "[" + json + "]";

jsonarray = jsonarray.fromobject(json);

list list = jsonarray.tolist(jsonarray, student.class);

system.out.println(list.size());

system.out.println(list.get(0));

list = jsonarray.tolist(jsonarray);

system.out.println(list.size());

system.out.println(list.get(0));

} catch (exception e) {

e.printstacktrace();
