我怎樣才能更改JavaScript腳本轉換爲jQuery的功能代碼

Question

嘿，夥計們是新來的jQuery，我怎樣才能改變這種javascript代碼到jQuery的功能代碼，以便我把它時，我想在任何物體

LIKE：$("#profile_img").uploader();

顯然這段代碼工作正常，但我的問題是我必須填充代碼，每次我需要上傳一個文件在不同的文件輸入上傳。

var input = document.getElementById("choosen_feeds_image"), 
      formdata = false; 

if (window.FormData) { 
    formdata = new FormData(); 
    document.getElementById("feeds_upload_btn").style.display = "none"; 
} 

if (input.addEventListener) { 
    input.addEventListener("change", function (evt) { 
     var i = 0, len = this.files.length, img, reader, file; 

     document.getElementById("response").innerHTML = "" 

     for (; i < len; i++) { 
      file = this.files[i]; 
      if (!!file.type.match(/image.*/)) { 
       if (window.FileReader) { 
        reader = new FileReader(); 
        reader.onloadend = function (e) { 
         showUploadedItem(e.target.result); 
        }; 
        reader.readAsDataURL(file); 
       } 
       if (formdata) { 
        formdata.append("feeds_image", file); 
       } 

       if (formdata) { 
        $.ajax({ 
         url: "member/feeds_image_upload", 
         type: "POST", 
         data: formdata, 
         processData: false, 
         contentType: false, 
         success: function (res) { 
          if (res.length <= 40) { 
           document.getElementById('feeds_image_response').innerHTML = res; 
           $("#feeds_image_response").css('display', 'none'); 
          } else { 
           document.getElementById("response").innerHTML = res; 
           $("#response").css('display', 'none'); 
          } 
         } 
        }); 
       } 
      } else { 
       document.getElementById("response").innerHTML = ""; 
       alert("Sorry, You choose unsupported file"); 
      } 
     } 

    }), false 
};

，你可以在函數內部的所有像這樣輸入

function uploader(){ 
    console.log('myFuntionUploader'); 
} 

，然後調用這樣

uploader();
