How do I input date in forms with xhtml or html4?

Question

well I know it's easier on html5, but I have to use html4 or xhtml and I can't find any info without html5 somehow. Can anyone help and explain me how I can input a date?

<input type="text" name ="sometext">

The normal html4 or xhtml doesn't seem to have the type date as the type of input.

Thanks in advance.

This question has been asked & answered on some other StackOverflow threads, but as I'm hitting the same problem, here's more info.

Using the jQuery DatePicker is a good start, but it does not enforce format or min/max value integrity outside of the actual calendar popup. Meaning, you can type or paste some bad stuff.

Here's 2 links to sites that demo how to do it the "old way" in JS with a function: http://www.javascriptkit.com/script/script2/validatedate.shtml http://www.w3resource.com/javascript/form/javascript-date-validation.php

And here's a StackOverflow link to another pretty nice way to do it: Detecting an "invalid date" Date instance in JavaScript

Personally, I need validation and restriction to min and max date ranges (SQL hates dates before 1/1/1773 and somebody tried that in my app). I'm going to wire up a function that tells me if a date string is valid, and then wire that up to the input's onchange event.

Here's the HTML for mine:

I'm also using ASP.NET and jQuery's DatePicker, so the key element for folks is the onblur event.

Here's the JS for the FixValidDate() function:

var availableDateFormats = ["mmddyyyy","mm/dd/yyyy","mm-dd-yyyy","yyyy/mm/dd","yyyy-mm-dd"];
function FixValidDate(txtDate,nulls, minDate, maxDate) {
    //debugger;
    formats = 
    {
        'mmddyyyy':{
            're':/^(\d{1,2})(\d{1,2})(\d{4})$/,
            'month': 1,'day': 2, year: 3
        },
        'mm/dd/yyyy':{
            're':/^(\d{1,2})[/](\d{1,2})[/](\d{4})$/,
            'month': 1,'day': 2, year: 3
        },
        'mm-dd-yyyy':{
            're':/^(\d{1,2})[-](\d{1,2})[-](\d{4})$/,
            'month': 1,'day': 2, year: 3
        },
        'yyyy/mm/dd':{
            're':/^(\d{4})[/](\d{1,2})[/](\d{1,2})$/,
            'month': 2,'day': 3, year: 1
        },
        'yyyy-mm-dd':{
            're':/^(\d{4})[-](\d{1,2})[-](\d{1,2})$/,
            'month': 2,'day': 3, year: 1
        }
    }

    dateText = txtDate.value;
    matched = false;
    for(i=0; i<availableDateFormats.length; i++)
    {
        f = formats[availableDateFormats[i]];
        match = dateText.match(f.re);
        if(match)
        {
            matched = true;
            month = match[f.month];
            day = match[f.day];
            year = match[f.year];
            //TODO validate if the numbers make sense
            txtDate.value = month+"/"+day+"/"+year;
        }
    }
    if (!matched && nulls) {
        txtDate.value = "";
        return false;
    } else {
        var timestamp = Date.parse(txtDate.value);

        if (isNaN(timestamp) == false) {
            var d = new Date(timestamp);

            if (minDate != null) {
                if (d < minDate) {
                    txtDate.value = "";
                    return false;    
                }

            }

            if (maxDate != null) {
                if (d > maxDate) {
                    txtDate.value = "";
                    return false;
                }
            }

        } else {
            txtDate.value = "";
            return false;
        }
    }
    return true;
}

This is from an old library I've used for JS stuff for about a decade. You could easily find another JS validation function and swap mine out.

In my function, I required to accept a variety of date formats, and if it's a bad format, I blank out the field and keep the user in the same box. You could change that up.

HTML4 doesn't have any tags to input date by default.All you need to do is include third party library like JQUERY.

Checkout this example http://jqueryui.com/datepicker/

The basic input element is all that HTML (other than HTML5) has. You should have a label, with associated markup, for all text input. Normally you should also include information about the expected input format, as this varies by language and culture, e.g.

<label for="birth">Date of birth (day/month year):</label>
<input id="birth" type="text" name="birth" size="10">

You should also pre-check the user input client-side, with JavaScript, to give the user fast response in case of data error. Naturally, the checks should be duplicated server-side.
