[英]How do I stop a runaway setInterval() timer in JavaScript
setInterval hangs when I hold the left mouse button down and sequentially press the right button. 当我按住鼠标左键并依次按右键时,setInterval会挂起。 setInterval will not clear after that.
之后,setInterval将不会清除。
var timer = 0;
document.getElementById('c_3').onmousedown = function(e) {
timer = setInterval(function() {myFunction();}, 30);
if (e.which == 2 || e.which == 3) {
clearInterval(timer);
}
}
This is how it works now ... 现在是这样的...
let timer = 0;
document.getElementById('c_3').onmousedown = function(e) {
if (e.which == 1) {
timer = setInterval(function() {myFunction();}, 30);
}
if (e.which == 2 || e.which == 3) {
document.getElementById('c_3').oncontextmenu = function() {
return false;
}
clearInterval(timer);
}
}
document.getElementById('c_3').onmouseup = function() {
clearInterval(timer);
}
