jQuery Number Text Field Validation Using Regex On Input Field

jQuery Number Text Field Validation Using Regex

Below is the full example of how to validate number using regex

var pattern = new RegExp("(^(\-?)([0-9]{0,12}?)(\\.)([0-9]){0,12}$)|(^(\-?)([0-9]){0,12}$)");

$(document.body).on("keypress", "input[type='text'].number", function (e) {
    if (e.which == 0 || e.which == 8) return true;
    var v = getTextFieldValue(this, String.fromCharCode(e.which));
    $("div").html(v);
    return pattern.test(v);
});

document.addEventListener("paste", function (e) {
    var v, f = $(e.target), ov = f.val();
    if (window.clipboardData && window.clipboardData.getData) { // IE
        v = window.clipboardData.getData('Text');
    }
    else if (e.originalEvent && e.originalEvent.clipboardData && e.originalEvent.clipboardData.getData) {
        v = e.originalEvent.clipboardData.getData('text/plain');
    }
    else if (e.clipboardData && e.clipboardData.getData) {
        v = e.clipboardData.getData('text/plain');
    }
    v = getTextFieldValue(f[0], v);
    if (!pattern.test(v)) e.preventDefault();
    $("div").html(v);
});

function getTextFieldValue(input, nv) {
    var v = input.value, i = input.selectionStart, j = input.selectionEnd;

    if (i == 0 && j == v.length) return nv;
    else if (i != j || i > 0) return v.substr(0, i) + nv + v.substr(j);
    else if (i == 0) return nv + v;
    else return v + nv;
}

$("input[type='text'].number").focus();

And finally you can use below regex to test your number:
^[-+]?(?:\.[0-9]{1,12}|[0-9]{1,12}(?:\.[0-9]{0,12})?)(?:[eE][-+]?[0-9]{1,12})?$

You can experience above example in JsFiddle

Configuring Grails DDL | Table Configuration | Grails DDL Schema Configuration | Table Schema Structure

Configuring Grails DDL | Table Configuration | Grails DDL Schema Configuration | Table Schema Structure


You need to create your own configuration class as below:

package com.multidb.gorm

import org.codehaus.groovy.grails.commons.GrailsApplication
import org.codehaus.groovy.grails.orm.hibernate.cfg.GrailsAnnotationConfiguration
import org.hibernate.HibernateException
import org.hibernate.cfg.Configuration
import org.hibernate.dialect.Dialect
import org.hibernate.tool.hbm2ddl.DatabaseMetadata
import org.hibernate.tool.hbm2ddl.SchemaUpdateScript

class MyDbConfigClass extends GrailsAnnotationConfiguration {
    private GrailsApplication grailsApplication
    public static Configuration configuration = null

    @Override
    protected void secondPassCompile() {
        super.secondPassCompile()
        if (!configuration) {
            configuration = this
        }
    }

    @Override
    String[] generateDropSchemaScript(Dialect dialect) throws HibernateException {
        return checkAndRemoveIgnoredTables(super.generateDropSchemaScript(dialect));
    }

    @Override
    String[] generateSchemaCreationScript(Dialect dialect) throws HibernateException {
        return checkAndRemoveIgnoredTables(super.generateSchemaCreationScript(dialect));
    }

    @Override
    List<SchemaUpdateScript> generateSchemaUpdateScriptList(Dialect dialect, DatabaseMetadata databaseMetadata) throws HibernateException {
        return super.generateSchemaUpdateScriptList(dialect, databaseMetadata)
    }

    @Override
    String[] generateSchemaUpdateScript(Dialect dialect, DatabaseMetadata databaseMetadata) throws HibernateException {
        List<SchemaUpdateScript> scripts = super.generateSchemaUpdateScriptList(dialect, databaseMetadata)
        return SchemaUpdateScript.toStringArray(scripts)
    }

    private static String[] checkAndRemoveIgnoredTables(String[] sqlStatements) {
        println(sqlStatements)
        return sqlStatements
    }

    @Override
    void setGrailsApplication(GrailsApplication application) {
        // Run superclass method
        super.setGrailsApplication(application)

        // Inject Grails application reference
        this.grailsApplication = application
    }
}

Below is DataSource configuration:

dataSource {
    configClass = com.multidb.gorm.MyDbConfigClass
    driverClassName = "com.mysql.jdbc.Driver"
    dbCreate = "create"
    url = "jdbc:mysql://localhost/grails_db"
    username = "grails"
    password = "grails"
}

JavaScript jQuery Phone Number Validation Using Regex Pattern

Below is the regex to check valid phone number:

var regex = /(^(\+?[0-9]+)?((\s|\-|\.)[0-9]+)+$)|(^\(\+?[0-9]+\)((\s|\-|\.)[0-9]+)+$)|(^[0-9]+$)/i;

Regex check result as below:

+39 347 12 34 567 is valid = true
(+333)-696 900 is valid = true
(+333) -696 900 is valid = false
(+333)-696 900 is valid = true
(+333-696 900 is valid = false
+333-696 900 is valid = true
