Question

所以我试图将JSON对象设置为名为＆＃34; itemArray＆＃34;的变量。设置JSON对象的函数（＆＃34; findCharItems（）＆＃34;）在发生对JSON对象的引用之前被调用。但是findCharItems（）中的post方法似乎要等到initialSetup（）完成，直到它进行ajax post调用。

因此，itemArray已设置 - 只是在我希望它被调用时。

我有几个控制台日志。以下是发生的顺序：

undefined（console.log（charPlaceID）;）

functions.js：69在findCharItems里面

functions.js：48 intitalSetup - itemArray：

var itemArray;

function initialSetup() {

    findCharItems();
    $("#multiInv").hide();
    $("#multiEquip").hide();
    $("#multiSkills").hide();
    $("#multiPeople").hide();
    $("#multiParty").hide();
    $(".mapScreen").css({"background-image": "url('./images/StallwardVillage.png')",

    $(".hpMpScreen").text("HP: " + charCurHP + "/" + charMaxHP + " Stamina: " + charCurStamina + "/" + charMaxStamina);
    $(".willScreen").text("MP: " + charCurMP + "/" + charMaxMP + " Will: " + charCurWill + "/" + charMaxWill);

    $("#multiStats").html("<table class='statTbl'><tr><td colspan='2'>" + charName + "'s Stats</td></tr>" +
            "<tr><td>Health: </td><td>" + charMaxHP + "</td></tr>" +

            "<tr><td>Intellect: </td><td>" + charIntellect + "</td></tr>" +
            "<tr><td>Wisdom: </td><td>" + charWisdom + "</td></tr></table>");



    $("#multiInv").append("<table><tr><td colspan='2'>Inventory</td></tr>");
    $("#multiEquip").append("<table><tr><td colspan='2'>Equip</td></tr>");
    console.log("intitalSetup - itemArray:" + itemArray);
    for (var i = 0; i < itemArray.item.length; i++) {
        var unequipButton = "<div class='unequipBtn'>Unequip</div>";
        var equipButton = "<div class='equipBtn'>Equip</div>";

        if (itemArray.item[i].isEquipped == 'true') {
            $("#multiEquip").append("<tr><td>" + itemArray.item[i].itemName + "</td><td>" + unequipButton + "</td></tr>");
        } else if (itemArray.item[i].type == 'clothing' || 'armor' || 'leather') {
            $("#multiInv").append("<tr><td>" + itemArray.item[i].itemName + "</td><td>" + equipButton + "</td></tr>");
        } else {
            $("#multiInv").append("<tr><td>" + itemArray.item[i].itemName + "</td><td></td></tr>");
        }
    }
    $("#multiInv").html("</table>");
    $("#multiEquip").html("</table>");



}

function findCharItems() {
    console.log("Inside findCharItems");
    $.post("findCharItems.php").done(function (data) {
        console.log("findCharItems - data:" + data);
        itemArray = JSON.parse(data);
        console.log("findCharItems - itemArray:" + itemArray);
    });
}

function findChar() {
    $.post("findChar.php").done(function (data) {
        var jsonData = JSON.parse(data);
        var charFound = jsonData.character.length;
        if (charFound > 0) {
            charPlaceID = jsonData.character[0].placeID;
            console.log(charPlaceID);
            charName = jsonData.character[0].name;
            charGender = jsonData.character[0].gender;
            charAgility = jsonData.character[0].agility;
            charStrength = jsonData.character[0].strength;
            charIntellect = jsonData.character[0].intellect;
            charWisdom = jsonData.character[0].wisdom;
            charMaxHP = jsonData.character[0].maxHP;
            charCurHP = jsonData.character[0].curHP;
            charMaxMP = jsonData.character[0].maxMP;
            charCurMP = jsonData.character[0].curMP;
            charMaxStamina = jsonData.character[0].maxStamina;
            charCurStamina = jsonData.character[0].curStamina;
            charMaxWill = jsonData.character[0].maxWill;
            charCurWill = jsonData.character[0].curWill;
            charExperience = jsonData.character[0].experience;
            charLevel = jsonData.character[0].level;
            $("#gameLayout").show();
            initialSetup();
        } else {
            $("#characterCreation").show();
        }




    });
}

为什么会发生这种情况？我希望在对它的引用发生之前设置itemArray。但是我需要在调用itemArray之前调用findChar（），因为它会检查是否有任何字符要查找itemArray。

感谢您的时间。

Ajax post方法被推迟。在我期待它之后调用
