function ajaxFileUpload() { $.ajaxFileUpload ( { url: uri, secureuri: false, fileElementId: 'upFile', dataType: 'content', //这里修改为content success: function (data, status) { alert(data); }, error: function (data, status, e) { alert(e); } } ) }
结果返回的json数据如猜测,json数据被包含在一个<pre></pre>的标签中.
网上查了下原因,是因为Server端的Response上加上了contentType="application/json"。但有时后端这么做是必须的,
所以修改ajaxFileUpload源码,将<pre></pre>标签去掉,如下:
uploadHttpData: function( r, type ) { var data = !type; data = type == "xml" || data ? r.responseXML : r.responseText; // If the type is "script", eval it in global context if ( type == "script" ) jQuery.globalEval( data ); // Get the JavaScript object, if JSON is used. if ( type == "json" ) { 以下为新增代码/// data = r.responseText; var start = data.indexOf(">"); if(start != -1) { var end = data.indexOf("<", start + 1); if(end != -1) { data = data.substring(start + 1, end); } } ///以上为新增代码/// eval( "data = " + data); } // evaluate scripts within html if ( type == "html" ) jQuery("").html(data).evalScripts(); return data; }
或者是在返回的“content”类型数据后
得到 JSON 数据
