我想在primefaces中自定义fileupload UI组件，其中inturn使用blueimp fileupload.js。我想用我的自定义模板覆盖默认的primefaces模板，并将渲染的模板附加到div“#errorMessage_wbMessages”而不是默认的“.fileupload-content”
我尝试将uploadContent和uploadTemplate设置如下，但它不起作用。
fileLoader是fileupload组件
中属性widgetVar的给定名称fileLoader.uploadContent = $("#errorMessage_wbMessages");
fileLoader.cfg.uploadTemplate = '<div class="ui-message-fatal ui-corner-all"><a href="#" class="ui-messages-close" onclick="$(this).parent().slideUp();return false;"><span class="ui-icon ui-icon-close"></span></a><span class="ui-messages-fatal-icon"></span><ul><li><span class="ui-messages-fatal-summary">File Upload Issue :{{if error === "maxFileSize"}}File Limit exceeded{{else error === "minFileSize"}}File Limit exceeded{{else error === "acceptFileTypes"}}Invalid File{{else error === "maxNumberOfFiles"}}Max number of files exceeded.{{else}}${error}{{/if}}</span></li></ul></div>';
