I can't get this working:
var x = 1;
while (x == 1) {
}
function changeX(val) {
if (val == 1) {
x = 1;
} else if (val == 0) {
x = 0;
break;
}
}
and no matter what I do, I can't get this working. What I want to do is: I want the loop to stop working when I choose "0" or type it or anything. I have to use break/continue .
No matter what I do, I get wrong use of break or my browser crashes.
PS. In HTML part I put
<input type="text" value="1" onchange="changeX(this.value)">
Making your code work:
While will block the browsers thread. Therefore, you cannot click. Do:
var x=false;
function react(){
if(x){return;}
//your code
console.log("sth");//e.g.
setTimeout(react,0);
}
react();
Now you can do your UI stuff
function changeX(val) {
if (val == 0) {
x = true;
}
}
What you really want:
var timer=false;
function input(val){
if(timer){
clearInterval(timer);
timer=false;
}
if(val){
timer=setInterval(function(){
val++;
alert(val);
if(val==10){
clearInterval(timer);
timer=false;
}
}, 1000);
}
<input oninput="input(this.value)">
<h3>Break Statement</h3>
<script>
let num=0;
while(num<5){
num++;
if((num==3)){
break;
}else{
document.write("num is: "+num+"<BR/>")
}
}
document.write("When if condition is true: while Loop Terminated");
</script>
<h3>Continue Statement</h3>
<script>
let val=0;
while(val<5){
val++;
if(val==3){
// skip the current loop iteration and jump to the next iteration
continue;
}
document.write("val = "+val+"<BR/>");
}
</script>
