Bootstrap With JQuery Validation Plugin


Answer :

for total compatibility with twitter bootstrap 3, I need to override some plugins methods:

// override jquery validate plugin defaults $.validator.setDefaults({     highlight: function(element) {         $(element).closest('.form-group').addClass('has-error');     },     unhighlight: function(element) {         $(element).closest('.form-group').removeClass('has-error');     },     errorElement: 'span',     errorClass: 'help-block',     errorPlacement: function(error, element) {         if(element.parent('.input-group').length) {             error.insertAfter(element.parent());         } else {             error.insertAfter(element);         }     } });

See Example: http://jsfiddle.net/mapb_1990/hTPY7/7/


For full compatibility with Bootstrap 3 I added support for input-group, radio and checkbox, that was missing in the other solutions.

Update 10/20/2017: Inspected suggestions of the other answers and added additional support for special markup of radio-inline, better error placement for a group of radios or checkboxes and added support for a custom .novalidation class to prevent validation of controls. Hope this helps and thanks for the suggestions.

After including the validation plugin add the following call:

$.validator.setDefaults({     errorElement: "span",     errorClass: "help-block",     highlight: function (element, errorClass, validClass) {         // Only validation controls         if (!$(element).hasClass('novalidation')) {             $(element).closest('.form-group').removeClass('has-success').addClass('has-error');         }     },     unhighlight: function (element, errorClass, validClass) {         // Only validation controls         if (!$(element).hasClass('novalidation')) {             $(element).closest('.form-group').removeClass('has-error').addClass('has-success');         }     },     errorPlacement: function (error, element) {         if (element.parent('.input-group').length) {             error.insertAfter(element.parent());         }         else if (element.prop('type') === 'radio' && element.parent('.radio-inline').length) {             error.insertAfter(element.parent().parent());         }         else if (element.prop('type') === 'checkbox' || element.prop('type') === 'radio') {             error.appendTo(element.parent().parent());         }         else {             error.insertAfter(element);         }     } });

This works for all Bootstrap 3 form classes. If you use a horizontal form you have to use the following markup. This ensures that the help-block text respects the validation states ("has-error", ...) of the form-group.

<div class="form-group">     <div class="col-lg-12">         <div class="checkbox">             <label id="LabelConfirm" for="CheckBoxConfirm">                 <input type="checkbox" name="CheckBoxConfirm" id="CheckBoxConfirm" required="required" />                 I have read all the information              </label>         </div>     </div> </div>

I use forms designed only with Twitter Bootstrap 3. I set defaults functions for validor and run only validate method with rules. I use Icons from FontAweSome, but you can use Glyphicons as in doc example.

enter image description here

jQuery.validator.setDefaults({     highlight: function (element, errorClass, validClass) {         if (element.type === "radio") {             this.findByName(element.name).addClass(errorClass).removeClass(validClass);         } else {             $(element).closest('.form-group').removeClass('has-success has-feedback').addClass('has-error has-feedback');             $(element).closest('.form-group').find('i.fa').remove();             $(element).closest('.form-group').append('<i class="fa fa-exclamation fa-lg form-control-feedback"></i>');         }     },     unhighlight: function (element, errorClass, validClass) {         if (element.type === "radio") {             this.findByName(element.name).removeClass(errorClass).addClass(validClass);         } else {             $(element).closest('.form-group').removeClass('has-error has-feedback').addClass('has-success has-feedback');             $(element).closest('.form-group').find('i.fa').remove();             $(element).closest('.form-group').append('<i class="fa fa-check fa-lg form-control-feedback"></i>');         }     } });

Done. After run validate function:

$("#default-register-user").validate({     rules: {         'login': {             required: true,             minlength: 5,             maxlength: 20         },         'email': {             required: true,             email: true,             minlength: 5,             maxlength: 100         },         'password': {             required: true,             minlength: 6,             maxlength: 25         },         'confirmpassword': {             required: true,             minlength: 5,             maxlength: 25,             equalTo: "#password"         }     } });

Converting A String To Int In Groovy

Answer : Use the toInteger() method to convert a String to an Integer , e.g. int value = "99".toInteger() An alternative, which avoids using a deprecated method (see below) is int value = "66" as Integer If you need to check whether the String can be converted before performing the conversion, use String number = "66" if (number.isInteger()) { int value = number as Integer } Deprecation Update In recent versions of Groovy one of the toInteger() methods has been deprecated. The following is taken from org.codehaus.groovy.runtime.StringGroovyMethods in Groovy 2.4.4 /** * Parse a CharSequence into an Integer * * @param self a CharSequence * @return an Integer * @since 1.8.2 */ public static Integer toInteger(CharSequence self) { return Integer.valueOf(self.toString().trim()); } /** * @deprecated Use the CharSequence version * @see #toInteger(CharSequence) */ @Deprecated public static Integer toInteger(String self) { return toInteg

"Cannot Create Cache Directory /home//.composer/cache/repo/https---packagist.org/, Or Directory Is Not Writable. Proceeding Without Cache"

Answer : if anyone pass through here, this is shorter solution: sudo chown -R $USER $HOME/.composer it seems to me the group information is missing in your command sudo chown -R <user> /home/<user>/.composer/cache/repo/https---packagist.org Shoud be sudo chown -R <user>:<group> /home/<user>/.composer/cache/repo/https---packagist.org But to avoid other permission issues, I would rather advise: sudo chown -R <user>:<group> /home/<user>/.composer/cache (you'll need access to other folders in there) and sudo chown <user>:<group> /home/<user>/.composer To make sure your user has permissions enough on the global composer folder. Mind the missing recursion so the user don't own keys created by root. If you need to find out the group: groups <user>

Android How Can I Convert A String To A Editable

Answer : As you probably found out, Editable is an interface so you cannot call new Editable() . However an Editable is nothing more than a String with Spannables, so use SpannableStringBuilder: Editable editable = new SpannableStringBuilder("Pass a string here"); If you only want to change the Spannables, never the text itself, you can use a basic SpannableString. Use Editable.Factory.getInstance().newEditable(str) From the android documentation: Returns a new SpannedStringBuilder from the specified CharSequence. You can override this to provide a different kind of Spanned.
