你應該真的考慮移動到這裏的模板模式。然後只需調用'$（'＃myTemplate'）。clone（）'來創建一個新的HTML實例並插入它。 – Tejs

您的表單屬性中有一個不匹配的引號。試試這個：是的ENCTYPE

function drawUploader() { 
    $("#drawUploader").append("<div id=\"upload_wrapper\">" + "<form id=\"upload\" name=\"upload\" enctype='multipart/form-data' method='post' action='index.php' target='upload_target'>" + "<input name='uploaded_file' type='file' size='30' id='uploaded_file' />" + "<input id='sent' name='sent' type='submit' value='Upload' />" + "</form>" + "</div>" + "<div id='loading' style='background:url(ajax-loader.gif) no-repeat left; height:50px; width:370px; display:none;'>" + "<p style='margin-left:40px; padding-top:15px;'>Uploading File... Please wait</p>" + "</div>" + "<div id='image_wrapper' style='display:none;'><img id='preview' src='' /></div>"); 
}

你<form>元素格式不正確。如果你在Chrome中使用開發工具，你會看到<div> upload_wrapper正在被添加，但其他的都沒有。

將所有\"更改爲單個'，它工作正常。
