JS对象转URL参数(原生JS和jQuery两种方式)

标签：javascript   url参数   对象   

$.ajax({
		type: "POST",
		url: "some.php",
		data: { name: "John", location: "Boston" }
    }).done(function( msg ) {
		alert( "Data Saved: " + msg );
    });

var params = '';
params += 'key1='+obj.key1;
params += 'key2='+obj.key2;
params += 'key3='+obj.key3;
params += 'key4='+obj.key4;
...

不用说太多,痛苦啊,就像苦力,一点也体会不到程序员高大上的感觉.或许,我们可以这样

var params = urlEncode(obj);

var parseParam=function(param, key){
    var paramStr="";
    if(param instanceof String||param instanceof Number||param instanceof Boolean){
        paramStr+="&"+key+"="+encodeURIComponent(param);
    }else{
        $.each(param,function(i){
            var k=key==null?i:key+(param instanceof Array?"["+i+"]":"."+i);
            paramStr+='&'+parseParam(this, k);
        });
    }
    return paramStr.substr(1);
};

//test
var obj={name:'tom','class':{className:'class1'},classMates:[{name:'lily'}]};
parseParam(obj);
//output: "name=tom&class.className=class1&classMates[0].name=lily"
parseParam(obj,'stu');
//output: "stu.name=tom&stu.class.className=class1&stu.classMates[0].name=lily"

/**
 * param 将要转为URL参数字符串的对象
 * key URL参数字符串的前缀
 * encode true/false 是否进行URL编码,默认为true
 * 
 * return URL参数字符串
 */
var urlEncode = function (param, key, encode) {
  if(param==null) return '';
  var paramStr = '';
  var t = typeof (param);
  if (t == 'string' || t == 'number' || t == 'boolean') {
    paramStr += '&' + key + '=' + ((encode==null||encode) ? encodeURIComponent(param) : param);
  } else {
    for (var i in param) {
      var k = key == null ? i : key + (param instanceof Array ? '[' + i + ']' : '.' + i);
      paramStr += urlEncode(param[i], k, encode);
    }
  }
  return paramStr;
};


var obj={name:'tom','class':{className:'class1'},classMates:[{name:'lily'}]};
console.log(urlEncode(obj));
//output: &name=tom&class.className=class1&classMates[0].name=lily
console.log(urlEncode(obj,'stu'));
//output: &stu.name=tom&stu.class.className=class1&stu.classMates[0].name=lily
