I try to declare bool variable and then check it, inside function, but I get error that there is unexpected identifier pointing to line where daysCreated is comparing to false
<script type="text/javascript">
var daysCreated = false;
function createDays() {
if daysCreated == false {
//do something
}
daysCreated = true;
}
}
function createDays is being called on button click inside document.
You forgot your parenthesis.
function createDays() {
if (daysCreated === false) {
//do something
}
daysCreated = true;
}
Also, you have a stray closing curly brace, and it's probably better to check for strict equality (e.g. ===).
Using a linter will catch things like this out of the gate. Here's a tutorial on using ESLint, for example.
This has nothing to do with scope.
The if test must be between parenthesis: if (condition)
if (daysCreated === false) {
This is not valid. You need brackets for your if statement like this:
function createDays() {
if (daysCreated == false) {
//do something
}
daysCreated = true;
}
You have a typo
function createDays() {
if (daysCreated === false) {
//do something
}
daysCreated = true;
}
There was a stray {
ifneeds to be wrapped in brackets.daysCreated- and returned that "internal" value, keeps the code a bit more modular perhaps.
