I have three variables that I need to put in the innerHTML of four spans. The variables I use are seconds, accurateclick, and inaccurateclick. The process I use to get these variables is fine. The problem is I can't figure out how to bring them over to another function. I will make a replica of what I have. This will be a simpler version.
var x;
var y;
var z;
function A(){
x = 1;
y = 2;
z = 3;
B();
}
function B(){
var a = "";
var b = "";
var c = "";
var d = "";
a += x;
b += y;
c += z;
d += (x + y + z);
}
What would happen is, instead of a being equal to 1, b being equal to 2, and c being equal to 3, they would all equal to undefined. I don't know why that is happening when x, y, and z are global variables. I thought they should change when set to a different value.
Here is my actual code:
var seconds;
var accurateclicks;
var inaccurateclicks;

Whenever I run it, it works up to this point
MiddleLabelTwo.innerHTML += seconds;
MiddleLabelThree.innerHTML += accurateclicks;
MiddleLabelFour.innerHTML += inaccurateclicks;
MiddleLabelFive.innerHTML += seconds + accurateclicks + inaccurateclicks;
It says seconds, accurateclicks, and inaccurateclicks are all undefined. I don't know why this would happen given that they were defined in the previous function [Game()].
try writing,
x = 1;
y = 2;
z = 3;
function A() {
B();
}
function B() {
var a = "";
var b = "";
var c = "";
var d = "";
a += x;
b += y;
c += z;
d += (x + y + z);
console.log(a, b, c, d);
}
A();
Reason: 'var' defines variables locally!
You did make two html files and this caused the js file to reload. This is why the global variables are declared again and are renewed to undefined.The solution is to work with one html file and to only reload the body.
My syntax was right, but as #Julie mentioned, the variables were being reloaded. How to get JS variable to retain value after page refresh? this helped me solve my problem.
I wrote some functions involving prime factorization and I noticed that when I identified my test paragraph (for testing the results of functions and such) as document.getElementById("text"), it worked fine. However, when I declared a global variable text as var text = document.getElementById("text"), and then substituted in text for the longer version, it no longer worked. I did, however, notice that it worked when I locally declared text. Why is this and how can I fix it? My JSFiddle is here: https://jsfiddle.net/MCBlastoise/3ehcz214/
And this is my code:
var text = document.getElementById("text");
function isPrime(num) {
var lastDigit = parseInt((num + "").split("").reverse()[0]);
if (typeof num !== "number" || num <= 1 || num % 1 !== 0) {
return undefined;
}
else if (num === 2) {
return true;
}
else if (lastDigit === 0 || lastDigit === 2 || lastDigit === 4 || lastDigit === 5 || lastDigit === 6 || lastDigit === 8) {
return false;
}
else {
for (var i = 2; i < num; i++) {
if (num % i === 0) {
return false;
}
}
return true;
}
}
function factorSplit(dig) {
if (typeof dig !== "number" || dig <= 1 || dig % 1 !== 0) {

}
else if (dig === 2) {
return undefined;
}

var factor;
for (var i = 2; i < dig; i++) {
if (dig % i === 0) {

The text is global, you just need to make sure the whole script file is included in the html. Here's an example of what I mean
Here in code snippets stackoverflow does this for us already.
var text = document.getElementById("text");
function isPrime(num) {
var lastDigit = parseInt((num + "").split("").reverse()[0]);

In the head the script runs/loads first and because you don't have the var's in a function they are never re-used they remain with the original value which is null since the document didn't exist at that time, then when the page loads all it has is access to the functions a call to the global var is null. This is why the code previously only worked when text = document.getElementById('text') was in a function.

I have some code in XCalc.js i want to support particular equation in(algebra equation,quadratic,linear,nonlinear equation) in based on equation how to programming in XCalc.js and how to show the steps based on equation so please help me to improve my code.refer this link:https://github.com/davepagurek/XCalc
so i bought a site witch is connected to a gestional programm in office..
the site is a little old, it's fully compatible with all the versions of internet explorer but not with other browsers(opera,safari,chrome,firefox...)
the only piece not working is a menu not opening correctly, when you click on it it doesn't happen anything or in chrome it changes the image but it doesn't upload the links. it seems that it doens't upload things in the hiddenframe...
in chrome it gives error in loadchildren function.
in firefox it gives error in function Toc_click ()
TypeError: window.event is undefined
[Break On This Error]
var eSrc = window.event.srcElement;
we searched for the problem and we think that the problem should be in this file
the problem should be a syntax problem, it's compatible in old browsers but not on the new ones. i cannot change completely the code as it is connected with other files(a lot) and sql server...
we already tried to change
document.frames["hiddenframe"].location.replace(strLoc);
by
document.getElementsByName("hiddenframe").location.replace(strLoc);
it doens't work and it doesn't work on IE either...
