JAVASCRIPT
在页面加载完毕之后，通过下面的方法来初始化该表单验证插件：
<script type="text/javascript">
$(document).ready(function() {
// Generate a simple captcha
function randomNumber(min, max) {
return Math.floor(Math.random() * (max - min + 1) + min);
};
$('#captchaOperation').html([randomNumber(1, 100), '+', randomNumber(1, 200), '='].join(' '));
$('#defaultForm').bootstrapValidator({
message: 'This value is not valid',
fields: {
username: {
message: 'The username is not valid',
validators: {
notEmpty: {
message: 'The username is required and can\'t be empty'
},
stringLength: {
min: 6,
max: 30,
message: 'The username must be more than 6 and less than 30 characters long'
},
regexp: {
regexp: /^[a-zA-Z0-9_\.]+$/,
message: 'The username can only consist of alphabetical, number, dot and underscore'
},
different: {
field: 'password',
message: 'The username and password can\'t be the same as each other'
}
}
},
email: {
validators: {
notEmpty: {
message: 'The email address is required and can\'t be empty'
},
emailAddress: {
message: 'The input is not a valid email address'
}
}
},
password: {
validators: {
notEmpty: {
message: 'The password is required and can\'t be empty'
},
identical: {
field: 'confirmPassword',
message: 'The password and its confirm are not the same'
},
different: {
field: 'username',
message: 'The password can\'t be the same as username'
}
}
},
confirmPassword: {
validators: {
notEmpty: {
message: 'The confirm password is required and can\'t be empty'
},
identical: {
field: 'password',
message: 'The password and its confirm are not the same'
},
different: {
field: 'username',
message: 'The password can\'t be the same as username'
}
}
},
captcha: {
validators: {
callback: {
message: 'Wrong answer',
callback: function(value, validator) {
var items = $('#captchaOperation').html().split(' '), sum = parseInt(items[0]) + parseInt(items[2]);
return value == sum;
}
}
}
}
}
});
});
</script>

配置参数
该表单验证插件的默认参数配置如下：
// The first invalid field will be focused automatically
autoFocus: true,
// Support declarative usage (setting options via HTML 5 attributes)
// Setting to false can improve the performance
declarative: true,
// The form CSS class
elementClass: 'fv-form',
// Use custom event name to avoid window.onerror being invoked by jQuery
// See #630
events: {
// Support backward
formInit: 'init.form.fv',
formError: 'err.form.fv',
formSuccess: 'success.form.fv',
fieldAdded: 'added.field.fv',
fieldRemoved: 'removed.field.fv',
fieldInit: 'init.field.fv',
fieldError: 'err.field.fv',
fieldSuccess: 'success.field.fv',
fieldStatus: 'status.field.fv',
localeChanged: 'changed.locale.fv',
validatorError: 'err.validator.fv',
validatorSuccess: 'success.validator.fv'
},
// Indicate fields which won't be validated
// By default, the plugin will not validate the following kind of fields:
// - disabled
// - hidden
// - invisible
//
// The setting consists of jQuery filters. Accept 3 formats:
// - A string. Use a comma to separate filter
// - An array. Each element is a filter
// - An array. Each element can be a callback function
// function($field, validator) {
// $field is jQuery object representing the field element
// validator is the BootstrapValidator instance
// return true or false;
// }
//
// The 3 following settings are equivalent:
//
// 1) ':disabled, :hidden, :not(:visible)'
// 2) [':disabled', ':hidden', ':not(:visible)']
// 3) [':disabled', ':hidden', function($field) {
//return !$field.is(':visible');
// }]
excluded: [':disabled', ':hidden', ':not(:visible)'],
// Map the field name with validator rules
fields: null,
// Live validating option
// Can be one of 3 values:
// - enabled: The plugin validates fields as soon as they are changed
// - disabled: Disable the live validating. The error messages are only shown after the form is submitted
// - submitted: The live validating is enabled after the form is submitted
live: 'enabled',
// Locale in the format of languagecode_COUNTRYCODE
locale: 'en_US',
// Default invalid message
message: 'This value is not valid',
// The field will not be live validated if its length is less than this number of characters
threshold: null,
// Whether to be verbose when validating a field or not.
// Possible values:
// - true: when a field has multiple validators, all of them will be checked, and respectively - if errors occur in
// multiple validators, all of them will be displayed to the user
// - false: when a field has multiple validators, validation for this field will be terminated upon the first encountered error.
// Thus, only the very first error message related to this field will be displayed to the user
verbose: true,
// ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
// These options mostly are overridden by specific framework
// ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
button: {
// The submit buttons selector
// These buttons will be disabled to prevent the valid form from multiple submissions
selector: '[type="submit"]',
// The disabled class
disabled: ''
},
control: {
// The CSS class for valid control
valid: '',
// The CSS class for invalid control
invalid: ''
},
err: {
// The CSS class of each message element
clazz: '',
// The error messages container. It can be:
// - 'tooltip' if you want to use Bootstrap tooltip to show error messages
// - 'popover' if you want to use Bootstrap popover to show error messages
// - a CSS selector indicating the container
// In the first two cases, since the tooltip/popover should be small enough, the plugin only shows only one error message
// You also can define the message container for particular field
container: null,
// Used to determine where the messages are placed
parent: null
},
// Shows ok/error/loading icons based on the field validity.
icon: {
valid: null,
invalid: null,
validating: null,
feedback: ''
},
row: {
// The CSS selector for indicating the element consists of the field
// You should adjust this option if your form group consists of many fields which not all of them need to be validated
selector: null,
valid: '',
invalid: '',
feedback: ''
