如何对json代码进行格式化显示

下面给一段javascript dump数据的一段代码，可以dump javascript的数据格式，非常好用
[javascript] view plain copy
function dump(arr,level) {
var dumped_text = "";
if(!level) level = 0;

//The padding given at the beginning of the line
var level_padding = "";
for(var j=0;j<level+1;j++) level_padding += " ";

if(typeof(arr) == 'object') { //Array/Hashes/Objects
for(var item in arr) {
var value = arr[item];

if(typeof(value) == 'object') { //If it is an array,
dumped_text += level_padding + "'" + item + "' /n";
dumped_text += dump(value,level+1);
} else {
dumped_text += level_padding + "'" + item + "' => /"" + value + "/"/n";
}
}
} else { //Stings/Chars/Numbers etc
dumped_text = "===>"+arr+"<===("+typeof(arr)+")";
}
return dumped_text;
}
