本文介绍了使用JavaScript实现对象和数组之间的相互转换方法。通过自定义函数`object2String`、`array2String`实现任意嵌套级别的对象或数组转换为字符串，并提供了`string2Object`、`string2Array`函数将字符串形式的对象或数组还原为原始数据类型。适用于需要序列化和反序列化JSON数据的场景。

function object2String(obj) {

var val, output = "";

if (obj) {    

output += "{";

for (var i in obj) {

val = obj[i];

switch (typeof val) {

case ("object"):

if (val[0]) {

output += i + ":" + array2String(val) + ",";

} else {

output += i + ":" + object2String(val) + ",";

}

break;

case ("string"):

output += i + ":'" + encodeURI(val) + "',";

break;

default:

output += i + ":" + val + ",";

           }

}

output = output.substring(0, output.length-1) + "}";

}

return output;

}



function array2String(array) {

var output = "";

if (array) {

output += "[";

for (var i in array) {

val = array[i];

switch (typeof val) {

case ("object"):

if (val[0]) {

output += array2String(val) + ",";

} else {

output += object2String(val) + ",";

}

break;

case ("string"):

output += "'" + encodeURI(val) + "',";

break;

default:

output += val + ",";

}

}

output = output.substring(0, output.length-1) + "]";

}

return output;

}



function string2Object(string) {

eval("var result = " + decodeURI(string));

return result;

}



function string2Array(string) {

eval("var result = " + decodeURI(string));

return result;

}
