在JavaScript中迭代时如何获取当前JSON属性的名称？
|
我有这样的变量内的JSON对象：
var chessPieces = {
\"p-w-1\" : {
\"role\":\"pawn\",
\"position\":{\"x\":1, \"y\":2},
\"state\":\"free\",
\"virgin\":\"yes\"
},
\"p-w-2\" : {
\"role\":\"pawn\",
\"position\":{\"x\":2, \"y\":2},
\"state\":\"free\",
\"virgin\":\"yes\"
},...
};
for (var piece in chessPieces){
//some code
}
chessPiece[piece].GiveMeTheName
//constructor for this function looks like this: function setPiece(piece,x,y);
function setPiece(chessPiece[piece],chessPiece[piece].position.x,chessPiece[piece].position.y){
//and here I need to get something like
piece.GiveMeTheName ==> which gives me string \"p-w-1\"
}
没有找到相关结果

已经不是对象的名称了吗？ JavaScript中的“ 5”为您提供密钥名称。 因此，当您执行时，它将打印出，等孝铜差
$.each(chessPieces, function(key, value) { //key = \"p-w-1\" //value = { \"role\":\"pawn\", ... } //this === value });辽躺
for (var piece in chessPieces){ alert(piece) }
