我一直在使用eval,它可以在一個瀏覽器中使用,但不是另一種(這些不是您的標準瀏覽器,而是與其他應用程序集成的瀏覽器)。在我的一個300+項目的對象被正確處理。在opther中,它處理從256到最後的項目,但跳過前255個項目! JSON也是正確的。任何替代eval?也許是一個jsonToObject函數。我正在寫我自己的時刻,但我受到了時間的限制,並希望我不必重新發明輪子eval()的替代品
任何想法或功能?
Verymuch讚賞
到目前爲止,我有這個,我要去嘗試,並基於它逆波蘭。不確定它是最有效的,但由於某種原因,它似乎是一個有趣的挑戰。我的一部分工作正在折磨着我所經歷的壓力,所以我需要現實一些,並詢問是否有任何方法可以與我分享。
var operatorStack = new Array();
var variableStack = new Array();
var valueStack = new Array();
var objectStack = new Array();
object.prototype.toJSON = function(){
}
function json(str){
this.value = str
}
/*
({"0":"Zero","1":{"A":"1","B":"2"},"2":{"C":"3","D":"4"},"3":{"E":"5","F":"^"}})
*/
json.prototype.toObject = function(){
var str = this.value;
var vbl = "";
var vlu = "";
for(var i = 0; i < str.length; i++){
var chr = str.charAt(i);
switch(chr){
case '{': //new Object();
objectStack.push = new Object();
operatorStack.push(chr);
break;
case '}': //close Object();
operatorStack.pop();
if(operatorStack[operatorStack.length-1] == ':'){
objectStack[objectStack.length-2][vbl] = objectStack[objectStack.length-1];
}else{
return obj;
}
break;
case '"':
if(operatorStack[operatorStack.length-1] == '"'){
operatorStack.pop();

}

operatorStack.push(chr);

break;

你爲什麼不使用JSON解析器? – 2011-05-19 15:07:52
