Custom date format with jQuery validation plugin

问题:

How can I specify a custom date formate to be validated with the Validation Plugin for jQuery?

回答1:

You can create your own custom validation method using the addMethod function. Say you wanted to validate \"dd/mm/yyyy\":

$.validator.addMethod(
    \"australianDate\",
    function(value, element) {
        // put your own logic here, this is just a (crappy) example
        return value.match(/^\\d\\d?\\/\\d\\d?\\/\\d\\d\\d\\d$/);
    },
    \"Please enter a date in the format dd/mm/yyyy.\"
);

And then on your form add:

$(\'#myForm\')
    .validate({
        rules : {
            myDate : {
                australianDate : true
            }
        }
    })
;

nickf\'s answer is good, but note that the validation plug-in already includes validators for several other date formats, in the additional-methods.js file. Before you write your own, make sure that someone hasn\'t already done it.

I personally use the very good http://www.datejs.com/ library.

Docco here: http://code.google.com/p/datejs/wiki/APIDocumentation

You can use the following to get your Australian format and will validate the leap day 29/02/2012 and not 29/02/2011:

jQuery.validator.addMethod(\"australianDate\", function(value, element) { 
    return Date.parseExact(value, \"d/M/yyyy\");
});

$(\"#myForm\").validate({
   rules : {
      birth_date : { australianDate : true }
   }
});

I also use the masked input plugin to standardise the data http://digitalbush.com/projects/masked-input-plugin/

$(\"#birth_date\").mask(\"99/99/9999\");

Here is an example for a new validation method that will validate almost any date format, including:

• dd/mm/yy or dd/mm/yyyy
• dd.mm.yy or dd.mm.yyyy
• dd,mm,yy or dd,mm,yyyy
• dd mm yy or dd mm yyyy
• dd-mm-yy or dd-mm-yyyy

Then, when you pass the value to the php you can convert it with strtotime

Here is how to add the method:

    $.validator.addMethod(\"anyDate\",
    function(value, element) {
        return value.match(/^(0?[1-9]|[12][0-9]|3[0-1])[/., -](0?[1-9]|1[0-2])[/., -](19|20)?\\d{2}$/);
    },
    \"Please enter a date in the format!\"
);

Then you add the new filter with:

$(\'#myForm\')
.validate({
    rules : {
        field: {
            anyDate: true
        }
    }
})

;

Here\'s a specific code sample which worked for me recently:

// Replace the builtin US date validation with UK date validation
$.validator.addMethod(
    \"date\",
    function ( value, element ) {
        var bits = value.match( /([0-9]+)/gi ), str;
        if ( ! bits )
            return this.optional(element) || false;
        str = bits[ 1 ] + \'/\' + bits[ 0 ] + \'/\' + bits[ 2 ];
        return this.optional(element) || !/Invalid|NaN/.test(new Date( str ));
    },
    \"Please enter a date in the format dd/mm/yyyy\"
);

I should note that this actually replaces the built-in date validation routine, though I couldn\'t see that this should cause an issue with the current plugin.

I then applied this to the form using:

$( \'#my_form input.date\' ).rules( \'add\', { date: true } );

This is me combining/modifying previous posts to achieve my desired result:

        // Override built-in date validator
        $.validator.addMethod(
            \"date\",
            function (value, element) {
                //Return            NB: isRequired is not checked at this stage
                return (value==\"\")? true : isDate(value);
            },
            \"* invalid\"
        );

Add Date validation after your validation config. I.e. after calling the $(form).validate({ ... }) method.

        //Add date validation (if applicable)
        $(\'.date\', $(frmPanelBtnId)).each(function () {
            $(this).rules(\'add\', {
                date: true
            });
        });

Finally, the main isDate Javascript function modified for UK Date Format

//Validates a date input -- http://jquerybyexample.blogspot.com/2011/12/validate-date-    using-jquery.html
function isDate(txtDate) {
    var currVal = txtDate;
    if (currVal == \'\')
       return false;

  //Declare Regex  
  var rxDatePattern = /^(\\d{1,2})(\\/|-)(\\d{1,2})(\\/|-)(\\d{4})$/;
  var dtArray = currVal.match(rxDatePattern); // is format OK?

  if (dtArray == null)
      return false;

   //Checks for dd/mm/yyyy format.
   var dtDay = dtArray[1];
   var dtMonth = dtArray[3];
   var dtYear = dtArray[5];

  if (dtMonth < 1 || dtMonth > 12)
      return false;
  else if (dtDay < 1 || dtDay > 31)
      return false;
  else if ((dtMonth == 4 || dtMonth == 6 || dtMonth == 9 || dtMonth == 11) && dtDay == 31)
      return false;
  else if (dtMonth == 2) {
      var isleap = (dtYear % 4 == 0 && (dtYear % 100 != 0 || dtYear % 400 == 0));
      if (dtDay > 29 || (dtDay == 29 && !isleap))
          return false;
  }

  return true;
}

Jon, you have some syntax errors, see below, this worked for me.

  <script type=\"text/javascript\">
$(document).ready(function () {

  $.validator.addMethod(
      \"australianDate\",
      function (value, element) {
        // put your own logic here, this is just a (crappy) example 
        return value.match(/^\\d\\d?\\/\\d\\d?\\/\\d\\d\\d\\d$/);
      },
      \"Please enter a date in the format dd/mm/yyyy\"
    );

  $(\'#testForm\').validate({
    rules: {
      \"myDate\": {
        australianDate: true
      }
    }
  });

});             

回答8:

$.validator.addMethod(\"mydate\", function (value, element) {

        return this.optional(element) || /^(\\d{4})(-|\\/)(([0-1]{1})([1-2]{1})|([0]{1})([0-9]{1}))(-|\\/)(([0-2]{1})([1-9]{1})|([3]{1})([0-1]{1}))/.test(value);

    });

you can input like yyyy-mm-dd also yyyy/mm/dd

but can\'t judge the the size of the month sometime Feb just 28 or 29 days.

@blasteralfred:

I got following rule validating correct date for me (DD MM YYYY)

jQuery.validator.addMethod(
\"validDate\",
function(value, element) {
    return value.match(/(?:0[1-9]|[12][0-9]|3[01]) (?:0[1-9]|1[0-2]) (?:19|20\\d{2})/);
},
\"Please enter a valid date in the format DD MM YYYY\"

);

For DD/MM/YYYY

jQuery.validator.addMethod(
\"validDate\",
function(value, element) {
    return value.match(/(?:0[1-9]|[12][0-9]|3[01])\\/(?:0[1-9]|1[0-2])\\/(?:19|20\\d{2})/);
},
\"Please enter a valid date in the format DD/MM/YYYY\"

);

This will not validate 01 13 2017 and 01/13/2017.

And also does not validate 50 12 2017 and 50/12/2017.
