I have a Paypal form which has been built using some borrowed code. The main purpose of the form is to add some optional extras to a standard product and send that data to the paypal checkout. It seems to be working quite well, but...
I have a text field that I want to be required when the related checkbox is checked and for it to be disabled, and therefore not required when its unchecked.
Crucially I need the data in the text field to be sent to the paypal shopping basket.
I have validation on another text field which will always be required, that works and sends the data to Paypal, but I'm a javascript newbie and can't get to grips with the second field.
This is the borrowed javascript
function Dollar (val) { // force to valid dollar amount
var str,pos,rnd=0;
if (val < .995) rnd = 1; // for old Netscape browsers
str = escape (val*1.0 + 0.005001 + rnd); // float, round, escape
pos = str.indexOf (".");
if (pos > 0) str = str.substring (rnd, pos + 3);
return str;
}
var amt,des,obj,val,op1a,op1b,op2a,op2b,itmn;
function ChkTok (obj1) {
var j,tok,ary=new Array (); // where we parse
ary = val.split (" "); // break apart
for (j=0; j<ary.length; j++) { // look at all items
// first we do single character tokens...
if (ary[j].length < 2) continue;
tok = ary[j].substring (0,1); // first character
val = ary[j].substring (1); // get data
if (tok == "#") amt = val * 1.0;
if (tok == "+") amt = amt + val*1.0;
if (tok == "%") amt = amt + (amt * val/100.0);
if (tok == "#") { // record item number
if (obj1.item_number) obj1.item_number.value = val;
ary[j] = ""; // zap this array element
}
// Now we do 3-character tokens...
if (ary[j].length < 4) continue;
tok = ary[j].substring (0,3); // first 3 chars

Any help would be much appreciated.
Give this code a try:
if (val == "" && obj1.elements["StampMe"].checked) {
// if the value of the stamp text field is empty and the user has checked the StampMe box
alert ("Enter data for " + obj.name);
return false;
}
(instead of)
//if (val == "" && tst) { // force an entry

// return false;

I have a program that is suppose to ask the user for their ID, First Name, Last Name, select a Rank (grade level), and the GPA. After all fields go through error checking, the data should then be put into an object called student. Next the student object should be pushed to the Summary Array. Displaying the first and last name, next line ID, next line Class Rank, next line GPA.
UPDATE CURRENTLY: all error checking (if/elses) works! Secondly, only the "--------" happens when Add Student is pressed besides the error checking.
Full Code:
var studentList = []
var studentID;
var studentFirst;
var studentLast;
var Rank;
var studentGPA;
var Summary = [];
studentID = document.querySelector("#Text1");

You need to initialize Summary to an empty array. Otherwise, Summary.push() gets an error because you can't push onto undefined.
The index of the prompt option in the Rank menu is 0, not 1, so you should check for that in the validation.
The Create() function reassigns all the variables that contain the input elements, replacing them with their values. You should use different variables, or just use the .value properties of the global variables.
You need to convert the value of Rank to a number before comparing with numbers.
You're missing a + at the end of the first line of the string you're appending to the DIV, so you're only adding the ---- line.
When checking for duplicates, you need to compare studentID.value with the studentID property of the array element, not the whole array element. And you should be searching Summary, not studentList.
var studentList = []

Rank has no selectedIndex because Rank is not an element or node.
Rank = document.getElementById('Select1').value;
You should set the value attribute on your option tags.
<option value="-1">(Select a Rank)</option>
if (Rank != -1) {
Currently I am building a website which this page uses an external javascript file, one of the main function is that in the form if the user does not enter anything or enter the wrong value and clicks on the submit button, a error message will show up above each section, but unfortunately mine when I click on the submit button it will still submit and will not show any error, I suspect that the Javascript file is not linked properly but I did set the path correctly as you can see in the picture and the on the HTML page.

I think you should check out this article: preventDefault() Event Method
When clicked, you should prevent the default behavior.
<script type="text/JavaScript" src="scripts/apply.js"></script>
Add the above script tag just before closing of body tag, it it best practice.
put a console.log("js file linked"); inside js file to test whether its linked or not.
Feel free to ask if it didn't work...
In the comments you mentioned
my friend told me its got to do with the last line in the js file "window.onload = init();
Your friend is correct - not sure if this is the only relevant thing, but here you are first running the function init() and the return value of that function is being saved into window.onload. Check out this example code:
function init() {
console.log(document.readyState);
}
window.onload = init();
console.log("Window onload is", window.onload);
Here init is run immediately and the return value of init will be saved to window.onload. This prints
loading
apply.js:315 Window onload is null
Instead, you should add a reference to the init function, so that the value of window.onload is your init function itself, not the return value; so the correction would be
function init() {
console.log(document.readyState);
}
window.onload = init;
console.log("Window onload is", window.onload);
// this one prints out
// Window onload is ƒ init() {console.log(document.readyState);}
// apply.js:311 complete
The "document.readyState" is used to check if the document has been loaded and parsed.
I have problem with coding html and js. the alert is not appearing upon submitting and i was following the template entirely. Anyone are able to find what is the problem? im sure my script file is in the same directory and the file is linked after i had tested by using document.write(""). And also what i wish the web page to do is to alert(gErrorMsg).

My Question is that i have one option set which is Gender inside two option Male and Female and one field Fullname. I want that when i select male inside option set the full name is concate with ms and when we select female full name is concate with miss
From what you've said and I understand you could try storing the two in variables and concatenate them like below. However It would be difficult to advise without code snippets.
let title = document.getElementById("title");
let fullName = document.getElementById("fullName");
let titleAndFullName = title + fullName;
Assuming you don't have jQuery restriction you can use:
$("input:radio").click(function() {
console.log($("input[name='Gender']:checked").data('name')+" "+$("input[name='fullname']").val());
});

<label> <input type="radio" name="Gender" data-name="Mr" checked="true">Male</label>
<label> <input type="radio" name="Gender" data-name="Ms">Female</label>
<input name="fullname" type="text" />
But if you do need to use pure javascript then you can use:
function check(){
var options = document.getElementsByName("Gender");
var fullname = document.getElementsByName("fullname");
for (var i = 0; i < options.length; i++) {
if (options[i].checked){
console.log(options[i].getAttribute("data-name") + " "+fullname[0].value);
}
}
}
<label> <input type="radio" name="Gender" data-name="Mr" checked="true" onclick="check()">Male</label>
<label> <input type="radio" name="Gender" data-name="Ms" onclick="check()">Female</label>
<input name="fullname" type="text" />
Use something like this.
if (selectedOption == "male") {
document.write("Mr. " + fullname);
} else if (selectedOption == "female") {
document.write("Miss " + fullname);
}
I applied this code and now it's working
==================================================
function GenderValidation(executionContext) {
var formContext = executionContext.getFormContext();
var FullName, gender;
if (formContext.getAttribute("cms_fullname") != null) {
var FullName = formContext.getAttribute("cms_fullname").getValue();
}
if (formContext.getAttribute("cms_gender") != null) {
var gender = formContext.getAttribute("cms_gender").getValue();
}
if (gender == 175650000) {
FullName = "Miss" + ' ' + FullName;
formContext.getAttribute("cms_fullname").setValue(FullName);
} else if (gender == 175650001) {
FullName = "Ms" + ' ' + FullName;
formContext.getAttribute("cms_fullname").setValue(FullName);
}
}
I'm trying to write a condition where:
if A is true and B is not, then it displays error_message_1
if B is true and A is not, it displays error_message_2
if both A and B are NOT true, displays error_message_3
First I tried writing all conditions in the same if...else if statement but it was very confusing so I tried putting them in different if statements and the code for that is below. the problem with this is that the third condition statement is always overridden by the first condition.
Code using html and javascript:
function calculatePrice() {
var tourType;
var payDate;
var returnTrip;
var extra = 0;
var tourCost = 0;
var discount = 0;
for (var i = 1; i <= 3; i++) {
tourType = document.getElementById("ans" + i);
if (tourType.checked == true) {
tourCost += parseFloat(tourType.value);
}
}
if (tourCost == 0 && discount !== 0) {
alert("Please select a Tour type");
return;
}
for (var a = 1; a <= 3; a++) {
payDate = document.getElementById("date" + a);
if (payDate.checked == true) {
discount += parseFloat(payDate.value);
}
}
if (discount == 0 && tourType !== 0) {
alert("Please select a Payment date.");
return;
}
for (var u = 1; u <= 1; u++) {
returnTrip = document.getElementById("return" + u);
if (returnTrip.checked == true) {
extra += parseFloat(returnTrip.value);
}
}
tourCost = tourCost - discount * tourCost + extra
tourCost = parseInt(tourCost)
if (tourCost == 0 && discount == 0) {
alert("Please select a Tour Type and Payment Date.");
return;
} else {
alert("The approximate cost of the holiday is $" + tourCost);
return;
}
}

Basically what I tried to do at first was to see whether any radio buttons were selected and base my if conditions on those. i tried using if (button.selected) but since each radio button has a different id, it was too long and I didn't know how to group them into one variable which I can use.
if A is true and B is not, then it displays error_message_1
if B is true and A is not, it displays error_message_2
if both A and B are NOT true, displays error_message_3
Is best written with the last condition first:
if (!A && !B) { // both are false
display(error_message_3);
} else if (!A) { // if A is false here, B must be true
display(error_message_2);
} else if (!B) { // if B is false here, A must be true
display(error_message_1);
} else { // both are true
display(no_error);
}
The conditions that you asked are :
if A is true and B is not, then it displays error_message_1
if B is true and A is not, it displays error_message_2
if both A and B are NOT true, displays error_message_3
To check if something is true you need to check if it equals to one, not zero.
