Terremotos Chile 8.4

Chile — A strong 8.3-magnitude earthquake struck off Chile’s coast on Wednesday, shaking buildings in cities around the country and forcing the authorities to evacuate residents along the 2,690-mile coast after tsunami warnings were issued. At least eight deaths were reported.

The quake hit at 7:54 p.m. west of Illapel, about 177 miles north of the capital, Santiago, and was felt in São Paulo, Brazil, more than 2,100 miles away. This caused what's known as an 'Earthquake Swarm' pictured below.

Custom jQuery validation plugin client side validation rules

When using jQuery Validation plugin setting up a new validator for a Html form is easy. Adding custom rules for validation is just as easy. Creating a custom rule on the client side could be more efficient than doing server side validation after the form is submitted.

Take for instance this javascript that creates a Validation object for a Html5 input element of type number:

// your Validation object

Var myValidator;

// Place custom validation rule here

// setting up the rules and message for the input element

myValidator = $( "#form1" ).validate({

    rules: {

        input1: { // selector of your input textbox

            digits: true,

            minlength: 9,

            maxlength: 9,

            messages: {

                digits: "Value has to be a number",

                minlength: $.validator.format("Value {0} is to low"),

                maxlength: $.validator.format("Value {0} is too high")

            }

        }

    },

    showErrors: function(errorMap, errorList){

            // place you validation error summary rendering code here

        });

    }

});

Now if you had a javascript function bound to the input element's keyup, input events your call to validate the value of the input element could be similar to the following javascript:

$( "#input1" ).bind( "keyup input", function(e) {

        myValidator.element( "#input1" );

    }

});

Now the custom rule part. Take for instance you wanted to prevent a value to be submitted that was already on display in a different element on the form. Instead of performing server side validation or making a separate ajax call, add a custom validation method to the jQuery Validation plugin. (The syntax is available at http://jqueryvalidation.org/jQuery.validator.addMethod/).

// Place custom validation rule here

// addMethod ( method-name-string, function(value, element){

//  validation code

//}, validation-message-string );

// e.g.

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

    var currentVal = $( "#txtBoxCurrentValue" ).text();

    if ( value === currentVal ) {

        return false;

    } else {

        return true;

    }

}, "That value is already set" );

Now update you rules section for input1 in your validator object to be:

    rules: {

        input1: { // selector of your textbox

            digits: true,

            minlength: 9,

            maxlength: 9,

            notequalto: true, // no quotes around the new method name, must validate to true

            messages: {

                digits: "Value has to be a number",

                minlength: $.validator.format("Value {0} is to low"),

                maxlength: $.validator.format("Value {0} is too high")

            }

MSBuild TransformXMl Task when converting from VS 2010 to VS 2012

Sometimes within a VS project Xml files are used to hold​ configuration settings for different build types, e.g., Debug vs. Release, etc.

A build warning will be displayed such as:

The "TransformXml task could not be loaded from the assembly C:\Program Files (x86)\MSBuild\Microsoft\VisualStudio\v10.0\Web\Microsoft.Web.Publishing.Task.dll.

This warning means that you migrated your VS 2010 project into a VS 2012 solution successfully, but, forgot to change the references for VS 2010 MSBuild assemblies to VS 2012 ( which is v11.0 ).

To Fix:

- Unload the project in the VS 2012 IDE, and edit the project file.

- Change all Microsoft.Web.Publishing.Task.dll version v10.0 references to v11.0

- Change the $(MSBuildExtensionsPath) variable name to $(MSBuildExtensionsPath32)

- Save your edits and reload the project

                digits: "Value has to be a number",
                minlength: $.validator.format("Value {0} is to low"),
                maxlength: $.validator.format("Value {0} is too high")
            }
        }
    },
    showErrors: function(errorMap, errorList){
            // place you validation error summary rendering code here
        });
    }

    } else {
        return true;
    }
}, "That value is already set" );

Now update you rules section for input1 in your validator object to be:
    rules: {
        input1: { // selector of your textbox
            digits: true,
            minlength: 9,
            maxlength: 9,
            notequalto: true, // no quotes around the new method name, must validate to true
            messages: {
                digits: "Value has to be a number",
                minlength: $.validator.format("Value {0} is to low"),
                maxlength: $.validator.format("Value {0} is too high")
            }

Now you have a custom validation rule for comparing a value against another Html element on the same form. Happy validating!
