AJAX fileupload-TypeError : not a function ajaxSubmit ()

표준 POST로 작동하지만 AJAX POST 요청으로 작동하지 않는 플러그인이 있습니다.

이 함수로 Firebug에서 함수가 아님 오류가 발생합니다.

TypeError : jQuery (…). ajaxSubmit is not a function

jQuery(this).ajaxSubmit(options); 

이 마법이 구출되었습니다. http://codeimpossible.com/2010/01/13/solving-document-ready-is-not-a-function-and-other-problems/

( function($) { } ) ( jQuery ); 

내 플러그인과 함께 대기열에 추가되는 js 파일입니다. 헤더에로드됩니다.

jQuery(document).ready(function(){ var options = { target: "#output", // target element(s) to be updated with server response beforeSubmit: beforeSubmit, // pre-submit callback success: afterSuccess, // post-submit callback uploadProgress: OnProgress, //upload progress callback resetForm: true // reset the form after successful submit } jQuery("#nanny_app_upload").on("submit", function(e) { e.preventDefault(); alert("jQuery submit called"); jQuery(this).ajaxSubmit(options); alert("jQuery post submit"); // always return false to prevent standard browser submit and page navigation alert("Got this from the server: " + response); return false; }); //function after succesful file upload (when server response) function afterSuccess(){ alert("jQuery afterSuccess"); jQuery("#submit-btn").show(); //show submit button jQuery("#loading-img").hide(); //hide loading button jQuery("#progressbox").delay( 1000 ).fadeOut(); //hide progress bar } //function to check file size before uploading. function beforeSubmit(){ alert("jQuery beforeSubmit"); jQuery("#submit-btn").hide(); //hide submit button jQuery("#loading-img").show(); //show loading button jQuery("#output").html(""); } //progress bar function function OnProgress(event, position, total, percentComplete) { //Progress bar alert("jQuery OnProgress"); jQuery("#progressbox").show(); jQuery("#statustxt").show(); jQuery("#progressbar").width(percentComplete + "%") //update progressbar percent complete jQuery("#statustxt").html(percentComplete + "%"); //update status text if(percentComplete>50) { jQuery("#statustxt").css("color","#000"); //change status text to white after 50% } } }); 

다음은 하위 테마에서 생성 된 양식입니다.

//Nannie upload form add_action("action_nannie_upload_form", "do_action_nannie_upload_form"); function do_action_nannie_upload_form() { $url = plugins_url(); $plugins_url = $url . "/nannie-app/"; ?><br> An Upload FORM!<br> <form action="<?php echo admin_url("admin-ajax.php"); ?>" method="post" enctype="multipart/form-data"> <br> <?php wp_nonce_field("nannie_app_upload","nannie_upload_ajax_nonce"); ?> <!-- Add new File --> <span class="btn btn-file">Select file: <input name="FileInput" type="file" /></span> <button type="submit" class="btn">Upload</button> </form> <img src="<?php echo $plugins_url; ?>images/ajax-loader.gif" style="display:none;" alt="Please Wait"/> <div style="display:none;"><div></div > <div>0%</div></div> <div></div> <br> <br> <hr/> <script src="<?php echo get_stylesheet_directory_uri(); ?>/plugins/form/jquery.form.js"></script> <script src="<?php echo get_stylesheet_directory_uri(); ?>/plugins/uload/ajaxFileUpload.js"></script> <?php } 

다음은 양식에서 호출하는 작업입니다. 제출. AJAX 헤더 확인을 제거하면 파일이 업로드되고 빈 페이지로 리디렉션됩니다.
