So again Julio, instead of point to code that obviously flawed in some functional way.
1. Why does this loop not stop when stop button pushed?
The syntax tell it to do so but apparently Javascript or dome doesn't care.
2. Whey does it not write out value to textfield as the syntax tell, but apparently Javascript do not give a shit about syntactical order of the things to do.
<HTML>
<HEAD>
<script>
var run=false;
function getRandomInt(max) {
return Math.floor(Math.random() * Math.floor(max));
}
//Head = 1 Tail = 0
function streaks(){
j=0;
streak=0;consecutive=0;
document.getElementById("textout").value="***WAIT***/n";
choice=document.getElementById("mychoice").value;
run=true;
if (choice=="head"){
//while (j<1000000000){
while (run==true){
myval=getRandomInt(2);
if(myval==1){
//alert(consecutive);
consecutive=consecutive+1;
} else {
//alert("CONSECUTIVE "+consecutive+" STREAK "+streak);
if (consecutive>streak){
mytext="TRY "+j+" STREAK "+choice+" "+consecutive+"\n";
streak=consecutive;
document.getElementById("textout").value+=mytext;
//console.log(document.getElementById("textout").value);
}
consecutive=0;
}
j++;
}
} else if (choice=="tail"){
//while (j<1000000000){
while (run==true){
myval=getRandomInt(2);
if(myval==0){
consecutive=consecutive+1;
} else {
if (consecutive>streak){
mytext="Try "+j+" Consecutive "+choice+" "+consecutive+"\n";
streak=consecutive;
document.getElementById("textout").value+=mytext;
//console.log(document.getElementById("textout").value);
}
consecutive=0;
}
j++;
}
}
}
function stop(){
run=false;
}
