arrayToJson将数组转化为json格式的js代码

函数代码:

function arrayToJson(o) { 
var r = []; 
if (typeof o == "string") return "\"" + o.replace(/([\'\"\\])/g, "\\$1").replace(/(\n)/g, "\\n").replace(/(\r)/g, "\\r").replace(/(\t)/g, "\\t") + "\""; 
if (typeof o == "object") { 
if (!o.sort) { 
for (var i in o) 
r.push(i + ":" + arrayToJson(o[i])); 
if (!!document.all && !/^\n?function\s*toString\(\)\s*\{\n?\s*\[native code\]\n?\s*\}\n?\s*$/.test(o.toString)) { 
r.push("toString:" + o.toString.toString()); 
} 
r = "{" + r.join() + "}"; 
} else { 
for (var i = 0; i < o.length; i++) { 
r.push(arrayToJson(o[i])); 
} 
r = "[" + r.join() + "]"; 
} 
return r; 
} 
return o.toString(); 
}

演示代码:


function arrayToJson(o) {
var r = [];
if (typeof o == "string") return "\"" + o.replace(/([\'\"\\])/g, "\\$1").replace(/(\n)/g, "\\n").replace(/(\r)/g, "\\r").replace(/(\t)/g, "\\t") + "\"";
if (typeof o == "object") {
if (!o.sort) {
for (var i in o)
r.push(i + ":" + arrayToJson(o[i]));
if (!!document.all && !/^\n?function\s*toString\(\)\s*\{\n?\s*\[native code\]\n?\s*\}\n?\s*$/.test(o.toString)) {
r.push("toString:" + o.toString.toString());
}
r = "{" + r.join() + "}";
} else {
for (var i = 0; i < o.length; i++) {
r.push(arrayToJson(o[i]));
}
r = "[" + r.join() + "]";
}
return r;
}
return o.toString();
}
