I need to - Create a HTML form with a text entry field and a button.. When a number is entered in the text entry field and the button clicked a Javascript function called DayOfTheWeek() is invoked. This function uses a switch statement to determine the day of the week corresponding to the number entered, i.e if the number entered is 1 the message “It’s Monday” is displayed, if the number entered is 2 the message “It’s Tuesday” is displayed and so on. If a number which is not between 1-7 is entered then the message “Not a valid day of the week” is displayed.
my html
<input type="text" name="text1"/>
<input type="button" value="Click me" onclick="days(text1.value);"/>
my java script
function days(dayOfTheWeek)
{
switch (dayOfTheWeek) {
case “1”:
alert(“It\’s Monday”);
break;
case “2”:
alert(“It\’s Tuesday”);
break;
case “3”:
alert(“It\’s Wednesday”);
break;
case “4”:
alert(“It\’s Thursday”);
break;
case “5”:
alert(“It\’s Friday”);
break;
case “6”:
alert(“It\’s Saturday”);
break;
case “7”:
alert(“It\’s Sunday”);
break;
default:
alert(“Not a valid day”);
break;
}
}
PLEASE HELP I keep getting an error with firebug saying days is not defind
function days(dayOfTheWeek) {
var weekday=new Array(7);
weekday[0]="Sunday";
weekday[1]="Monday";
weekday[2]="Tuesday";
weekday[3]="Wednesday";
weekday[4]="Thursday";
weekday[5]="Friday";
weekday[6]="Saturday";
var n = weekday[dayOfTheWeek];
return n;
}
Your updated code
<input type="text" name="text1" id="text1" />
<input type="button" value="Click me" onclick="javascript:days(parseInt(document.getElementById('text1').value));" />
<script language=javascript>
function days(dayOfTheWeek)
{
switch (dayOfTheWeek) {
case 1:
alert("It\’s Monday");
break;
case 2:
alert("It\’s Tuesday");
break;
case 3:
alert("It\’s Wednesday");
break;
case 4:
alert("It\’s Thursday");
break;
case 5:
alert("It\’s Friday");
break;
case 6:
alert("It\’s Saturday");
break;
case 7:
alert("It\’s Sunday");
break;
default:
alert("Not a valid day");
break;
}
}

why is this code only giving me the default value
<!DOCTYPE html>
<html>
<body>
<p id= "demo"></p>
<input id="age" />
<button onclick="document.getElementById('demo').innerHTML=text">try it</button>
<script>
var text;
age = document.getElementById('age').value;
switch (age) {
case 10:
text = "diuble";
break;
case 13:
text = "puberty";
break;
case 18:
text = "Beer!";
break;
default:
text = "Looking forward to the Weekend";
}
</script>
</body>
</html>
I have tried changing document.getElementById('age').value to 18, when i do that it gives me the output as beer! but right now its only giving me Looking Forward....
You are not calling a function onclick, and firing the code on document load. The right way to do it would be:
function getText(){
var text;
age = document.getElementById('age').value;
age = parseInt(age)
switch (age) {
case 10:
text = "diuble";
break;
case 13:
text = "puberty";
break;
case 18:
text = "Beer!";
break;
default:
text = "Looking forward to the Weekend";
}
document.getElementById('demo').innerHTML=text
}
<p id= "demo"></p>
<input id="age" />
<button onclick="getText()">try it</button>
I have five input fields, I need to validate all the fields by showing a circle type validation modal. It will be incremented dynamically.
Please find attached sample validation images.
Here is the code:
$("#field1, #field2, #field3").blur(function() {
var getImageName = $('#step-dwld').attr('src').slice(7, 30);
if( !this.value ){
$('#step-dwld').attr('src', 'images/'+getImageName);
} else{
switch (getImageName) {
case "step-bg.png":
$('#step-dwld').attr('src', "images/step-1.png");
break;
case "step-1.png":
$('#step-dwld').attr('src', "images/step-2.png");
break;
case "step-2.png":
$('#step-dwld').attr('src', "images/step-3.png");
break;
}
}
});
Because of your vague question without or with very less code it is hard for us to guess what your code is and your HTML structure, you need to create a Minimal, Complete, and Verifiable example so that others can help you.
However check this it might give you an idea on how to do it, I don't now your code this why and based on guesswork I implemented a similar one to simulate it

var validate = $('.validate'), score= 0;
validate.on('change', function(){
score = 0;
validate.each(function(){

console.log(score);
setImage(score);

Im trying to make a case statement but my variable for my first switch statement just goes to my default statement when i really have a string in my variable for the type of edge such as: "round", "square", "butt". I tested it with alert(tipoextremo) and it does contain the value "round", "square", or "butt".
For the second switch statement, i am trying to get my button names into the switch statement when i click a button in html and do that function inside the case, but when using alert("hi") it does not even go into the default statement meaning that it is being completely ignored in my javascript.

<button onclick = "button javascript.js">
What do you drive? </button>
I want the button to run my switch() in the button javascript.js file
var car = prompt('What car?');
switch(car) {
case 'ferrari':
document.write("you are probs a baller then");
break;
case "porsche":
document.write("do you ball hard?");
break;
case "dodge":
document.write("american cannot corner");
break;
default:
document.write("your car better be a subaru");
}
You can put the code in a function inside the javascript. Include the file in script tags and on click of the button, call that function. That will trigger the JS code only on click of the button.
Put this in the HTML,
<script src='button javascript.js'></script>
//Intermediate HTML code
<button onclick = "myButtonFun()">
What do you drive? </button>
And in the Javascript you can put in your code in the function myButtonFun()
function myButtonFun()
{
var car = prompt('What car?');
switch(car) {
case 'ferrari': document.write("you are probs a baller then");
break;
case "porsche": document.write("do you ball hard?");
break;
case "dodge": document.write("american cannot corner");
break;
default: document.write("your car better be a subaru");
}
}
Make your code into a function and, on the button, use
type="button"
and
onclick="yourFunction()"
You need to wrap your script into function and invoke it on button click:
<button onclick = "askForCar();">What do you drive?</button>
var askForCar = function() {
//you script here
};
var askCar = function() {
switch (prompt('What car?')) {
case 'ferrari':
document.write("you are probs a baller then");
break;
case "porsche":
document.write("do you ball hard?");
break;
case "dodge":
document.write("american cannot corner");
break;
default:
document.write("your car better be a subaru");
}
};
<button onclick="askCar();">What do you drive?</button>

You forgot the : character from your switch in cases 3-5. Here's the working code:
var secretNumber = prompt("Pick a number between 1 and 5:", "");
secretNumber = parseInt(secretNumber);
switch (secretNumber)
{
case 1:
document.write("Too low!");
break;
case 2:
document.write("Too low!");
break;
case 3:
document.write("You guessed the secret number!");
break;
case 4:
document.write("Too high!");
break;
case 5:
document.write("Too high!");
break;
default:
document.write("you did not enter a number between 1 and 5!");
break;
}
document.write("<br />Execution continues here");
