Question

我想使用该按钮在Ajax请求english.json和french.json之间切换，但是我不确定如何操作。有谁可以帮助我吗？下面的代码仅调用JSON中的每个对象。

<!doctype html>


<html>

<body>
    <h1> Frenching</h1>
    <button id="toggle"> toggle</button>
    <p> This program changes names from English to French</p>
    <h3 id="name"> </h3>
</body>

 </html>


<script src="https://code.jquery.com/jquery-3.3.1.min.js"> </script>
<script>
//Ajax request
$("document").ready(function () {
    $.getJSON("French.json").done(function (french) {
        console.log(french.lastName)
    });

    $.getJSON("english.json").done(function (english) {
        console.log(english.lastName)
    });
});
</script>

//seperate files
French.Json
{
    "firstName": "Merci",
    "lastName": " Claudè"
}


English.Json
{
    "firstName": "Gracias",
    "lastName": "Claude"
}

我创建了一个全局对象以将对象存储在JSON中，然后创建了一个触发英语和法语json的切换功能。

//sets a global variable 
   var globalState = {
        viewState: true,
        english: null,
        french: null
    };
//toggles function 
   $("#toggle").click(function toggleGlobalState () {
        globalState.viewState = !globalState.viewState; // sets the viewState object to false
        console.log(globalState); // toggles true and false
        if(globalState.viewState) { // if true change name to french
            $("#firstname")[0].innerHTML = globalState.french.firstName
            $("#lastname")[0].innerHTML = globalState.french.lastName
        } else { // if false change name to english
            $("#firstname")[0].innerHTML = globalState.english.firstName
            $("#lastname")[0].innerHTML = globalState.english.lastName
        }
   });
//Ajax request
$("document").ready(function () {
    $.getJSON("French.json").done(function (french) {
        globalState.french = french; // sets the french name objects in the json to a global object
        $("#firstname")[0].innerHTML = globalState.french.firstName
            $("#lastname")[0].innerHTML = globalState.french.lastName
    }).then(function(result) {
        console.log(globalState.french.firstName); //checks
    });
    $.getJSON("english.json").done(function (english) {
        globalState.english = english; // sets the english name objects in the json to a global object
    });
});

如果您不介意同时调用这两个Ajax请求，则应将结果存储在变量中，然后切换结果。

1,14

如果只想在需要时触发该ajax，则应在按下按钮时触发它。

public Form1()
    {
        InitializeComponent();
    }

    private void button1_Click(object sender, EventArgs e)
    {
        Random myRandom = new Random();
        int suitNo, cardNo;
        string suit = "", card = "";

        suitNo = myRandom.Next(1, 5);
        cardNo = myRandom.Next(1, 14);

        if (suitNo == 1)
        {
            suit = "Hearts";
        }
        if (suitNo == 2)
        {
            suit = "Diamonds";
        }
        if (suitNo == 3)
        {
            suit = "Clubs";
        }
        if (suitNo == 4)
        {
            suit = "Spades";
        }

        switch (cardNo)
        {
            case 1:
                card = "Ace";
                break;
            case 2:
                card = "Two";
                break;
            case 3:
                card = "Three";
                break;
            case 4:
                card = "Four";
                break;
            case 5:
                card = "Five";
                break;
            case 6:
                card = "Six";
                break;
            case 7:
                card = "Seven";
                break;
            case 8:
                card = "Eight";
                break;
            case 9:
                card = "Nine";
                break;
            case 10:
                card = "Ten";
                break;
            case 11:
                card = "Jack";
                break;
            case 12:
                card = "Queen";
                break;
            case 13:
                card = "King";
                break;
        }

        label1.Text = "Your card is a " + card + " of " + suit;
