关于JSON.parse(),JSON.stringify(),jQuery.parseJSON()的用法

var str = '[{"href":"baidu.com","text":"test","orgId":123,"dataType":"curry","activeClass":"haha"}]'; 
 
JSON.parse(str); 

var obj = [{"href":"baidu.com","text":"test","orgId":123,"dataType":"curry","activeClass":"haha"}]; 
 
JSON.stringify(obj); 

"[{"href":"baidu.com","text":"test","orgId":123,"dataType":"curry","activeClass":"haha"}]" 

var str = '[{"href":"baidu.com","text":"test","orgId":123,"dataType":"curry","activeClass":"haha"}]'; 
 
jQuery.parseJSON(str); 

parseJSON: function( data ) { 
  // Attempt to parse using the native JSON parser first 
  if ( window.JSON && window.JSON.parse ) { 
    return window.JSON.parse( data ); 
  } 
 
 
  if ( data === null ) { 
    return data; 
  } 
 
 
  if ( typeof data === "string" ) { 
 
 
    // Make sure leading/trailing whitespace is removed (IE can't handle it) 
    data = jQuery.trim( data ); 
 
 
    if ( data ) { 
      // Make sure the incoming data is actual JSON 
      // Logic borrowed from http://json.org/json2.js 
      if ( rvalidchars.test( data.replace( rvalidescape, "@" ) 
        .replace( rvalidtokens, "]" ) 
        .replace( rvalidbraces, "")) ) { 
 
 
        return ( new Function( "return " + data ) )(); 
      } 
    } 
  } 
 
 
  jQuery.error( "Invalid JSON: " + data ); 
},
