uploadify附件上传 传参

首先 在刚加载jsp时就加入上传方法，所以 formDate 中的参数 zFileName是页面刚加载时 exp1的值 ，后来通过js方法赋值不被读过来，
如果 你想要获得这个值，可在 调用uploadify之前先把参数加入，见 save 方法

$(document).ready(function() {

$(‘#edit_file_upload‘).uploadify({
 ???auto:false,
 ???buttonClass: "some-class",
 ???buttonCursor: ‘hand‘,
 ???height: 20,
 ???width: 90,
 ???buttonText: ‘<div>选择文件</div>‘,
 ???fileSizeLimit : ‘102400KB‘,
 ???fileObjName: ‘myfile‘,
 ???fileTypeExts: ‘*.*‘,
 ???multi: true,
 ???preventCaching: true,
 ???queueID : ‘edit_file_upload-queue‘,
 ???progressData: ‘percentage‘,
 ???overrideEvents : [‘onSelectError‘],
 ???formData: {‘typeId‘:‘1‘, ‘typeName‘:‘2‘,‘zFileName‘:$("#exp1").val(),‘id‘:‘${tEdasFlowApprove.id}‘,‘fileId‘:$("#fileId").val()},
 ???swf:‘${ctxStatic}/uploadify/uploadify.swf‘,
 ???uploader:‘${ctx}/flow/approve/tEdasFlowApprove/addFile;JSESSIONID=<shiro:principal property="sessionid"/>‘,
 ???onFallback : function() {//检测FLASH失败调用
 ???????alert("您未安装FLASH控件，无法上传图片！请安装FLASH控件后再试。");
 ???},
 ???onSelectError : uploadify_onSelectError,
 ???onUploadSuccess : function(file, data, response) {
 ???????$(‘#‘ + file.id).find(‘.data‘).html(‘上传完毕‘);
 ???????data = eval(‘(‘+data+‘)‘);
 ???????fileId = data.fileId + ",";
 ???????var old_val = $(‘#fileId‘).val();
 ???????$(‘#fileId‘).val(old_val + fileId);
 ???},
 ???onQueueComplete : function(queueData) {
 ???????var fileId = $("#fileId").val();
 ???????if((fileId!=(""))&&(fileId.substring(fileId.length-1)==(","))){
 ???????????$("#fileId").val(fileId.substring(0, fileId.length-1));
 ???????}
 ???????$("#inputForm").submit();

 ???},
 ???onUploadError : function(file, errorCode, errorMsg, errorString) {
 ???????$.messager.show({
 ???????????title:‘我的消息‘,
 ???????????msg: errorString,
 ???????????timeout:5000,
 ???????????showType:‘slide‘
 ???????});
 ???}
});


});


function save（）{

　　$("#edit_file_upload").uploadify("settings", "formData", {‘zFileName‘:$("input[name=exp1]").val()});
　　$(‘#edit_file_upload‘).uploadify(‘upload‘,‘*‘);

}
