Greater than or not equal to

My code here
if (parent4 && parent5 && parent6 && (_state[tree][parent4]) + (_state[tree][parent5]) + (_state[tree][parent6]) !== 8) {
return false;
} else {
return true;
}
It works, and has some of the elements I want, namely that if the sum of the three _states !== 8, it returns false.
I'll try to explain the logic I'm trying to achieve as simply as I can:
if par4 + par5 + par6 !>= 8
return false
if par4 + par5 !>= 8
return false
if par4 OR par5 OR par6 !>= 8
return false
else
return true
I abbreviated the code for simplicity and ease of understanding.
Swapping around return false and return true and changing it to >= doesn't work, because for all elements, even ones I don't mention here, it needs to go to return true by default.

How about this?
if (parent4 && parent5 && parent6) {
if ((_state[tree][parent4] + _state[tree][parent4] + _state[tree][parent4]) !== 8) {
return false;
} else {
return true;
}
}
Or in a one-liner:
if (parent4 && parent5 && parent6 && (_state[tree][parent4] + _state[tree][parent4] + _state[tree][parent4]) !== 8) {
return false;
} else {
return true;
}

How to check if switch is true or not to hide the div?

I have some problem when I check the function validation, I need when checking all the cassis is true hide the parent div * errors message *
var error_pass = false;
$('#pass').focusout(function(){
check_pass();
error_pass = false;
if(error_pass !== true){
console.log('its showing!');
}else{
$('.test').fadeOut('522');
}
});
function check_pass() {
var fpass= $('#pass').val();
switch(error_pass = true){
case(fpass.length < 6 ? $('#pass-error-message3').css('color','red'):$('#pass-error-message3').css('color','green') ):
$('#pass-error-message3').show();
case(fpass.search(/(?=.[a-z])(?=.*[A-Z])/) == -1 ? $('#pass-error-message4').css('color','red') : $('#pass-error-message4').css('color','green')):
$('#pass-error-message4').show();
case(fpass.search(/\d/) == -1 ? $('#pass-error-message2').css('color','red'):$('#pass-error-message2').css('color','green')):
$('#pass-error-message2').show();
default:break;
}
}

Use if else statements like this
function validation() {
var error = false;
if (fpass.length < 6) {
error = true;
$('#pass-error-message3').css('color', 'red').show();
} else {
$('#pass-error-message3').css('color', 'green');
}
if (fpass.search(/(?=.[a-z])(?=.*[A-Z])/) == -1) {
error = true;
$('#pass-error-message4').css('color', 'red').show();
} else {
$('#pass-error-message4').css('color', 'green')
}
if(fpass.search(/\d/) == -1){
error = true;
$('#pass-error-message2').css('color','red').show();
}else{
$('#pass-error-message2').css('color','green');
}
if(error === false){
hideParentDiv(); // Here hide the div
}
}
Much cleaner approach

Convert JavaScript ternary operator to if than else statement

I'm trying to convert the following ternary operator representation to an if-then else statement:
return 0 === r.length ? t ? O.toInvalid : null : o(r) ? null : O.toInvalid
Could you please help me to do this?

You could use this statement.
if (0 === r.length) {
if (t) {
return O.toInvalid;
} else {
return null;
}
} else {
if (o(r)) {
return null;
} else {
return O.toInvalid;
}
}

try this if else condition I optimize for you
if ( (!r.length && t) || (r.length && !o(r) ) ) {
return O.toInvalid;
} else {
return null;
}

Validating numeric values using JavaScript

I have the following code. It works fine for blank fields, but it doesn't catch the other numeric exceptions. What am I doing wrong?
function validateForm() {
var a = document.forms["Form"]["percentage"].value;
var b = document.forms["Form"]["minutes"].value;
if (a == null || b == null || a == "" || b == "") {
alert("Please Fill All Required Field");
return false;
} else if (isNan(a) == true || isNan(b) == true) {
alert("Please enter valid numeric values");
return false;
} else if (parseInt(a) > 100) {
alert("Percentage can't exceed 100");
return false;
} else if (parseInt(b) < 0 || parseInt(a) < 0) {
alert("Values can't be negative");
return false;
}
}

Change this line:
else if((isNan(a)==true) ||(isNan(b)==true)){
to this:
else if (isNaN(a) || isNaN(b)) {
as the function is named #isNaN(). Using == true in conditionals is quite redundant, so I removed them.
I have also made a fiddle for you. It contains the fixed code, and it is working well.

phone number validation with added input

I recently filled out a form and when I got to the phone number textBox I noticed some really cool things going on. As I entered my number, general phone symbols were getting added automatically. Example:
I start entering my area code '555'
and my input was changed to 1 (555)
to test what just happened I backspaced on the ) and it quickly added it back in.
So my question is, how do I get this input to happen?

I use a javascript library called automask - you dont see the mask but it wont let you type anything outside the mask
for instance if your mask is ###-###-#### then any other characters are ignored (ie not 0-9) and the dashes are put in automatically.
I can post the library if you would like to take a look at
example of implementation
<input type=text name=ssn onkeypress="return autoMask(this,event, '###-##-####');">
// email kireol at yahoo.com
// autoMask - an adaption of anyMask
//
// this will force #'s, not allowing alphas where the #'s are, and auto add -'s
function autoMask(field, event, sMask) {
//var sMask = "**?##?####";
var KeyTyped = String.fromCharCode(getKeyCode(event));
var targ = getTarget(event);
keyCount = targ.value.length;
if (getKeyCode(event) < 32)
{
return true;
}
if(keyCount == sMask.length && getKeyCode(event) > 32)
{
return false;
}
if ((sMask.charAt(keyCount+1) != '#') && (sMask.charAt(keyCount+1) != 'A' ) && (sMask.charAt(keyCount+1) != '~' ))
{
field.value = field.value + KeyTyped + sMask.charAt(keyCount+1);
return false;
}
if (sMask.charAt(keyCount) == '*')
return true;
if (sMask.charAt(keyCount) == KeyTyped)
{
return true;
}
if ((sMask.charAt(keyCount) == '~') && isNumeric_plusdash(KeyTyped))
return true;
if ((sMask.charAt(keyCount) == '#') && isNumeric(KeyTyped))
return true;
if ((sMask.charAt(keyCount) == 'A') && isAlpha(KeyTyped))
return true;
if ((sMask.charAt(keyCount+1) == '?') )
{
field.value = field.value + KeyTyped + sMask.charAt(keyCount+1);
return true;
}
return false;
}
function getTarget(e) {
// IE5
if (e.srcElement) {
return e.srcElement;
}
if (e.target) {
return e.target;
}
}
function getKeyCode(e) {
//IE5
if (e.srcElement) {
return e.keyCode
}
// NC5
if (e.target) {
return e.which
}
}
function isNumeric(c)
{
var sNumbers = "01234567890";
if (sNumbers.indexOf(c) == -1)
return false;
else
return true;
}
function isNumeric_plusdash(c)
{
var sNumbers = "01234567890-";
if (sNumbers.indexOf(c) == -1)
return false;
else
return true;
}
function isAlpha(c)
{
var lCode = c.charCodeAt(0);
if (lCode >= 65 && lCode <= 122 )
{
return true;
}
else
return false;
}
function isPunct(c)
{
var lCode = c.charCodeAt(0);
if (lCode >= 32 && lCode <= 47 )
{
return true;
}
else
return false;
}

If this was an aspx page, they were probably using the AJAX Control Toolkit MaskedEdit Extender. There is also the Masked Input plugin for jQuery.
