Best Practices for Cross-Browser Date Entering

This article explores the challenges and best solutions for implementing date input fields in various browsers. Due to inconsistent browser support for <input type="date"> and the ignorance of lang attributes, we need a robust solution to deal with date formats, UTC/local time issues, and differences between browsers.

Key points:

• Browser's support for <input type="date"> and lang attributes is uneven, resulting in the inability to display input widgets in non-native languages.
• Many JavaScript solutions try to improve support for date input, but few scripts can handle two different date formats that display and save data at the same time.
• Datepicker for jQuery UI is a well-tested and supported library that solves formatting issues with the altField option. While it can be integrated with Bootstrap, this requires creating a new theme file to ensure visual consistency.
• jQuery UI Datepicker does not support the datetime field. Trent Richardson's Timepicker plugin works as a solution, which behaves in line with the standard Datepicker widgets and uses datepicker.less files without additional work.

Browser compatibility test:

We tested various date input types (date, datetime, datetime-local, time, month, week), and found:

• No browser support datetime input type.
• Browsers that support datetime-local usually also support time and month, while week is less supportive.
• All browsers seem to ignore the lang properties, and the input widget always uses the date and time format set by the system.

Select the fallback script:

Many JavaScript solutions can improve support for cross-browser date input, but many have problems: maintenance is not active or cannot handle different date formats that display and save data.

Advantages of jQuery UI Datepicker:

jQuery UI Datepicker is a well-tested and well-maintained library with the altField option that is ideal for handling differences in display formats and save formats. It can be integrated with Bootstrap, but requires creating a custom theme.

Condition loading and code implementation:

In order to load jQuery UI Datepicker only when needed, you can use Modernizr for feature detection:

Modernizr.load({
    test: Modernizr.inputtypes.date,
    nope: [
        'jquery-ui-master/ui/core.js',
        'jquery-ui-master/ui/datepicker.js',
        'jquery-ui-master/ui/i18n/datepicker-it.js', // 替換為你的語言文件
        'jquery-ui-master/themes/base/core.css',
        'jquery-ui-master/themes/base/datepicker.css',
        'jquery-ui-master/themes/base/theme.css'
    ],
    callback: function() {
        // 回調(diào)函數(shù)，處理日期選擇器初始化和格式設置
        // ... (代碼與原文類似，但需根據(jù)實際情況調(diào)整) ...
    }
});

callback function, we need to create a hidden <input type="date"> for each altField element to store the date in the ISO format and use the datepicker method to set the display format and save format.

Bootstrap integration:

To better integrate with Bootstrap, you need to create a custom datepicker.less file, using Bootstrap's variables and Glyphicons icon. This requires importing the variables and Glyphicons files of Bootstrap and rewriting the style of the jQuery UI using the Less variable.

Timepicker plug-in:

For datetime fields, you can use Trent Richardson's Timepicker Add-on, which integrates seamlessly with Datepicker.

Summary:

By combining Modernizr's feature detection, jQuery UI Datepicker's altField options, and custom themes, we can create a cross-browser-compatible, easy to customize date input solution. Remember, these tips may eventually become obsolete as browsers continue to improve support for native date input.
