我想对其进行编辑,以便每次刷新页面时都不会更新计时器。
我搜索并且在我的情况下AJAX不是一个选项,因为我的代码页需要刷新,而计时器仍然是相同的。
另外,我试图将它保存在会话中,但这对JS不起作用。
JS:
var mins
var secs;
function cd() {
mins = 1 * m("5"); // change minutes here
secs = 0 + s(":01");
redo();
}
function m(obj) {
for(var i = 0; i < obj.length; i++) {
if(obj.substring(i, i + 1) == ":")
break;
}
return(obj.substring(0, i));
}
function s(obj) {
for(var i = 0; i < obj.length; i++) {
if(obj.substring(i, i + 1) == ":")
break;
}
return(obj.substring(i + 1, obj.length));
}
function dis(mins,secs) {
var disp;
if(mins <= 9) {
disp = " 0";
} else {
disp = " ";
}
disp += mins + " .";
if(secs <= 9) {
disp += "0" + secs;
} else {
disp += secs;
}
return(disp);
}
function redo() {
secs--;
if(secs == -1) {
secs = 59;
mins--;
}
document.cd.disp.value = dis(mins,secs); // setup additional displays here.
if((mins == 0) && (secs == 0)) {
window.alert(" Hey Time is up. Press OK to continue.");
window.location = "results_random.php" // redirects to specified page once timer ends and ok button is pressed
} else {
cd = setTimeout("redo()",1000);
}
}
function init() {
cd();
}
window.onload = init;
</script>
表格:
<form name="cd">
<label>
<span class="labe">Remaining Time</span>:
<input name="disp" type="text" class="clock" id="txt" value="10:00" size="10" readonly="true" align="right" border="1" />
<span class="labe">Minutes</span>
</form>
希望你能提供帮助,谢谢。
