Question

通过使用波纹管代码我计算2日期之间的差异，这是格式在字符串中 2017-12-19 17:19:35 我做了下面的代码，在谷歌浏览器中工作，但没有在safari中工作。

<?xml version="1.0" encoding="utf-8"?>
<resources>
    <style name="Theme.Splash" parent="android:Theme">
        <item name="android:windowBackground">@drawable/a</item>
        <item name="android:windowNoTitle">true</item>
    </style>
    <style name="MainTheme" parent="MainTheme.Base">
    </style>
    <!-- Base theme applied no matter what API -->
    <style name="MainTheme.Base" parent="Theme.AppCompat.Light.NoActionBar">
        <item name="windowNoTitle">true</item>
        <item name="windowActionBar">false</item>
        <item name="colorPrimary">@color/primary</item>
        <item name="colorPrimaryDark">@color/primaryDark</item>
        <item name="colorAccent">@color/accent</item>
        <item name="android:colorActivatedHighlight">@android:color/transparent</item>
        <item name="windowActionModeOverlay">true</item>
        <item name="alertDialogTheme">@style/AppCompatAlertDialogStyle</item>
        <item name="android:alertDialogTheme">@style/AppCompatAlertDialogStyle</item>
        <item name="android:datePickerDialogTheme">@style/AppCompatDateStyle</item>
        <item name="android:timePickerDialogTheme">@style/AppCompatDateStyle</item>
        <item name="colorControlNormal">@color/primaryDark</item>
        <item name="colorControlActivated">@color/primary</item>
    </style>
    <style name="AppCompatDateStyle" parent="Theme.AppCompat.Light.Dialog">
        <item name="colorAccent">@color/primary</item>
        <item name="colorPrimary">@color/primary</item>
        <item name="colorPrimaryDark">@color/primaryDark</item>
    </style>
    <style name="AppCompatAlertDialogStyle" parent="Theme.AppCompat.Light.Dialog.Alert">
        <item name="colorAccent">@color/primary</item>
    </style>
</resources>

在chrome var lastReportingTime = r.get('updatedate'); // 2017-12-19 17:19:35 var serverCurrentTime = r.get('currtime'); //2018-02-09 03:52:42 var diff = new Date(serverCurrentTime) - new Date(lastReportingTime); diff /= 60000; //diff converted in minutes. console.log('diff=',diff); // for chrome output is diff= 4445024000 // for safari output is diff= NaN中以分钟为单位返回结果但safari浏览器中的相同代码返回diff

你能解决这个问题吗？

Answer 1

您可以使用var mymap = L.map('map', { bounceAtZoomLimits: false })获取毫秒，然后减去。

参考和支持表： https://developer.mozilla.org/en-US/docs/Web/JavaScript/Reference/Global_Objects/Date/valueOf

Answer 2

日期构造函数的默认实现因浏览器而异。在Chrome中正确解析的某些字符串可能无法在Safari中正确解析。不使用new Date()，而是使用Ext.Date.parse(theDateString, theExpectedFormat)。 Docs

Answer 3

这对我有用

   // var lastReportingTime = r.get('updatedate'); // 2017-12-19 17:19:35
   // var serverCurrentTime = r.get('currtime'); //2018-02-09 03:52:42

     var lastReportingTime = "2017-12-19 17:19:35"
     var serverCurrentTime = "2018-02-09 03:52:42"
  
    var diff = new Date(serverCurrentTime.replace(/-/g, "/")) - new Date(lastReportingTime.replace(/-/g, "/"));
    diff /= 60000; //diff converted in minutes.

    console.log('diff=',diff);

Answer 4

使用Date.getTime（）进行数学运算： https://developer.mozilla.org/en-US/docs/Web/JavaScript/Reference/Global_Objects/Date/getTime

为什么新的Date（）函数在safari中不起作用？
