我正在使用javascript（主干网）创建Web应用程序。现在，我遇到了一个我无法解决的问题。我有一个包含日期和其他条件的表格，用于创建“冲刺”（参见图片）image of adding a sprint
这是“后记”的观点
var PostSprint = Backbone.View.extend({
el: '.sprintform',
render: function(options) {
var that = this;
var teamId = options.id;
var latestSprint = new LatestSprint({id:teamId});
var AccessToken = Cookies.get('AccessToken');
latestSprint.url = 'rest/latestSprint'+'/'+ teamId + '/' + AccessToken;
latestSprint.fetch({
success: function (latestSprint) {
if(latestSprint.attributes.result=='NotLoggedIn'){
router.navigate('#/notloggedin', {trigger: true});
}
if(latestSprint.attributes.result=='TokenExpired'){
router.navigate('#/tokenexpired', {trigger: true});
}
if(latestSprint.attributes.result=='Ok'){
var template = _.template($('#create-sprint-template').html(),{latestSprint: latestSprint});
that.$el.html(template);
$(function() {
if (!Modernizr.inputtypes['date']) {
$('input[type=date]').datepicker({
dateFormat: "yy-mm-dd"
});
}
});
}
},
error: function (er){
alert("Error loading (fetch) the sprint view. line 7 in PostSprint.js");
Backbone.history.loadUrl();
}
});
},
events:{
'submit .submitsprint': 'postSprint',
'change #weeks' : 'changeEndDate',
'change #enddate' : 'changeWeeks'
},
changeWeeks: function (ev) {
var startdate = moment($("#startdate").val());
var enddate = moment($("#enddate").val());
var duration = moment.duration(enddate.diff(startdate));
var dayInt = duration.asDays();
var weekInt = Math.ceil(dayInt / 7);
$("#weeks").val(weekInt);
},
changeEndDate: function (ev) {
var date = moment($("#startdate").val(), "YYYY-MM-DD");
date = moment(date).add('days', ($("#weeks").val() * 7)) ;
$("#enddate").val(moment(date).format('YYYY-MM-DD'));
},
postSprint: function (ev) {
var addSprintButton = $(ev.currentTarget);
addSprintButton.find("button").prop("disabled", true);
var sprintDetails = addSprintButton.serializeObject();
var tid = sprintDetails.teamid;
var sprint = new Sprint();
if (Date.parse(sprintDetails.startdate) < Date.parse(sprintDetails.enddate)){
var AccessToken = Cookies.get('AccessToken');
sprint.url = 'rest/sprint'+'/'+ AccessToken;
sprint.save(sprintDetails, {
success: function (sprint) {
if(sprint.attributes.result=='NotLoggedIn'){
router.navigate('#/notloggedin', {trigger: true});
}
if(sprint.attributes.result=='TokenExpired'){
router.navigate('#/tokenexpired', {trigger: true});
}
if(sprint.attributes.result=='Ok'){
//window.location.reload(true);
Backbone.history.loadUrl();
}
},
error: function (er){
alert("Error saving (save) the sprint view. line 53 in PostSprint.js");
}
});
}else{
alert("The start date must be earlier than the end date");
Backbone.history.loadUrl();
}
return false;
},
});
如您所见，我正在使用modernizr库来定义是否存在本机日期选择器，如果不使用jquery datepicker。
这是冲刺列表的视图

el: '.sprintlist',

var latestSprint;
var latestSprintTime = 0;
for(x in sprints.models) {
var endDate = Date.parse(sprints.models[x].attributes.enddate.replace(/-/g, " "));
if(endDate > latestSprintTime)
latestSprint = sprints.models[x];
latestSprintTime = endDate;
}
if(latestSprint) {
var dt = new Date(latestSprint.get('enddate'));
var dayOfMonth = dt.getDate();
dt.setDate(dayOfMonth + latestSprint.get('weeks')*7);
var month =dt.getMonth()+1;
if(month<10){month = "0"+month}
var day = dt.getDate();

我已经完成的工作是复制列表中最新冲刺的数据。因此，最后的结束日期将被复制到新冲刺的开始日期，此外还将复制持续时间和容量。因为复制了持续时间，所以自动设置了新的结束日期，因此日期仍然是可编辑的，然后显示日期选择器。
提供上述条件的HTML代码：
<script type="text/template" id="sprint-list-template">
<% var url = window.location.href;
var lastPart = url.substr(url.lastIndexOf('/') + 1);
%>
<h3>Sprint List : For Team ID <%= lastPart %></h3>
<hr />
<form class="form-inline submitsprint">
<table class="table table-responsive table-hover">

<!--<th>ID</th>-->

<th>End Date</th>
<th>Capacity</th>

<!--<th>Team_Id</th>-->

<tbody>
<% _.each(sprints, function(sprints) { %>

我是一名初级程序员，请原谅我的代码...
现在解决我的问题：在Internet Explorer Edge中，我的代码无法正常运行（如第一个图像所示），以下图像将问题可视化了
screenshot IE Edge
新添加的Sprint未填充最新Sprint的数据。
如果我检查元素，则值为“”。而如果我检查Firefox中的同一元素，则该值将填充正确的值。有人知道如何解决这个问题吗？
最佳答案
Internet Explorer不喜欢以您指定的格式解析日期。
Date.parse(sprints.models[x].attributes.enddate.replace(/-/g, " "));
您应该尝试使用类似jQuery.datepicker的插件将结束日期“转换”为所有浏览器都可以使用的东西。
Date.parse($.datepicker.parseDate('yy-mm-dd', sprints.models[x].attributes.enddate));
