功能：

var print = function(o){
    var str='';

    for(var p in o){
        if(typeof o[p] == 'string'){
            str+= p + ': ' + o[p]+'; </br>';
        }else{
            str+= p + ': { </br>' + print(o[p]) + '}';
        }
    }

    return str;
}

用法：

var myObject = {
    name: 'Wilson Page',
    contact: {
        email: 'wilson@hotmail.com',
        tel: '123456789'
    }  
}

$('body').append( print(myObject) );

正如之前所说，我发现的最简单的方法是

var getPrintObject=function(object)
{
    return JSON.stringify(object);
}

Javascript函数

<script type="text/javascript">
    function print_r(theObj){ 
       if(theObj.constructor == Array || theObj.constructor == Object){ 
          document.write("<ul>") 
          for(var p in theObj){ 
             if(theObj[p].constructor == Array || theObj[p].constructor == Object){ 
                document.write("<li>["+p+"] => "+typeof(theObj)+"</li>"); 
                document.write("<ul>") 
                print_r(theObj[p]); 
                document.write("</ul>") 
             } else { 
                document.write("<li>["+p+"] => "+theObj[p]+"</li>"); 
             } 
          } 
          document.write("</ul>") 
       } 
    } 
</script>

正在打印对象

<script type="text/javascript">
print_r(JAVACRIPT_ARRAY_OR_OBJECT);
</script> 

通过Javascript中的print_r

试试这个：

var object = this.window;
console.log(object,'this is window object');

输出：

我需要一种递归打印对象的方法，pagewil提供了答案（谢谢！）。我对它进行了一点更新，以包括一种打印到某个级别的方法，并添加间距，以便根据当前级别正确缩进，以便更易于阅读。

// Recursive print of object
var print = function( o, maxLevel, level ) {
    if ( typeof level == "undefined" ) {
        level = 0;
    }
    if ( typeof level == "undefined" ) {
        maxLevel = 0;
    }

    var str = '';
    // Remove this if you don't want the pre tag, but make sure to remove
    // the close pre tag on the bottom as well
    if ( level == 0 ) {
        str = '<pre>';
    }

    var levelStr = '';
    for ( var x = 0; x < level; x++ ) {
        levelStr += '    ';
    }

    if ( maxLevel != 0 && level >= maxLevel ) {
        str += levelStr + '...</br>';
        return str;
    }

    for ( var p in o ) {
        if ( typeof o[p] == 'string' ) {
            str += levelStr +
                p + ': ' + o[p] + ' </br>';
        } else {
            str += levelStr +
                p + ': { </br>' + print( o[p], maxLevel, level + 1 ) + levelStr + '}</br>';
        }
    }

    // Remove this if you don't want the pre tag, but make sure to remove
    // the open pre tag on the top as well
    if ( level == 0 ) {
        str += '</pre>';
    }
    return str;
};

用法：

var pagewilsObject = {
    name: 'Wilson Page',
    contact: {
        email: 'wilson@hotmail.com',
        tel: '123456789'
    }  
}

// Recursive of whole object
$('body').append( print(pagewilsObject) ); 

// Recursive of myObject up to 1 level, will only show name 
// and that there is a contact object
$('body').append( print(pagewilsObject, 1) ); 

这里有一种方法：

console.log("%o", obj);
