Hi folks,
I'm just starting with Javascript objects, and I'm having variable
scope issue that I can't seem to resolve. The following works:
function customClass() {
this.myFunc=function() {
// do something
}
}
window.onload=function() {
var foo=new customClass();
foo.test=function() {
interval=setInterval(function() {
if (test)
foo.increment();
else clearInterval(interval);
}, 400);
}
foo.test();
}
Trying to move the interval inside the object, however, fails:
function customClass() {
this.myFunc=function() {
// do something
}
this.test=function() {
interval=setInterval(function() {
if (test)
this.increment();
else clearInterval(interval);
},400);
}
}
window.onload=function() {
var foo=new customClass();
foo.test();
}
I have a feeling this is a scope problem, because javascript doesn't
throw an error. Any ideas?
