我使用jquery ajax上传带有进度条的视频和图像文件。我使用服务器端表单验证并检查重复条目。我的问题是进度条变得完整后显示验证错误消息。我想是这样的......jquery文件上传进度条
if form validation is correct
then show progress bar
else if form validation is not correct
then only show error message of form validation
else if duplicate entry
then only show error message of duplicate entry
这是我的js代码:
$.ajax({
url: ajaxUrl,
type: 'POST',
dataType: 'json',
processData: false,
contentType: false,
async: true,
data: formData,
xhr: function() {
//upload Progress
var xhr = $.ajaxSettings.xhr();
if (xhr.upload) {
xhr.upload.addEventListener('progress', function (event) {
var percent = 0;
var position = event.loaded || event.position;
var total = event.total;
if (event.lengthComputable) {
percent = Math.ceil(position/total * 100);
}
var temp = event.loaded/event.total*100;
//update progressbar
$('div#upload-progress').text(percent + "%");
$('div#upload-progress').css("width", + temp + "%");
}, true);
}
return xhr;
},
complete: function(xhr) {
if(xhr.responseText) {
//console.log(xhr);
}
},
success: function(data, status){
if (data.hasOwnProperty('form-error')) {
$.each(data['form-error'], function (key, value) {
$("span#span_" + key).text(value);
})
} else {
// Form validation is correct
}
},
error : function(xhr, textStatus, errorThrown) {
var data = xhr.responseText;
myWindow = window.open("data:text/html," + encodeURIComponent(data), "parent", "width=1000, height=600");
myWindow.focus();
}
});
谁能给我任何建议,如何做到这一点?
