2个javascript函数冲突?
我正在尝试在我的网站中实现 Javascript/PHP/AJAX 时钟,以便我可以拥有一个可以在不同时区运行的简单时钟(教程位于此处 http://networking.mydesigntool.com/viewtopic.php?tid=373&id=31)
这本身工作正常,但我已经页面上运行一个 javascript 秒表,两者似乎发生冲突,并且秒表工作时时钟不会显示。
这是时钟的脚本:
<script type="text/javascript">
function loadTime ()
{
http_request = false;
if(window.XMLHttpRequest)
{
// Mozilla, Safari,...
http_request = new XMLHttpRequest();
if(http_request.overrideMimeType)
{
// set type accordingly to anticipated content type
//http_request.overrideMimeType('text/xml');
http_request.overrideMimeType('text/html');
}
}
else if(window.ActiveXObject)
{ // IE
try
{
http_request = new ActiveXObject("Msxml2.XMLHTTP");
}
catch (e)
{
try
{
http_request = new ActiveXObject("Microsoft.XMLHTTP");
}
catch(e)
{
}
}
}
var parameters = "time=";
http_request.onreadystatechange = alertContents;
http_request.open('POST', 'time.php', true);
http_request.setRequestHeader("Content-type", "application/x-www-form-urlencoded");
http_request.setRequestHeader("Content-length", parameters.length);
http_request.setRequestHeader("Connection", "close");
http_request.send(parameters);
}
function alertContents()
{
if (http_request.readyState == 4)
{
if (http_request.status == 200)
{
result = http_request.responseText;
document.getElementById('clock').innerHTML = result;
}
}
}
</script>
<body onload="setInterval('loadTime()', 200);">
这是秒表的代码:
<script type="text/javascript">
window.onload = function()
{
stopwatch('Start');
}
var sec = 0;
var min = 0;
var hour = 0;
function stopwatch(text) {
sec++;
if (sec == 60) {
sec = 0;
min = min + 1;
} else {
min = min;
}
if (min == 60) {
min = 0;
hour += 1;
}
if (sec<=9) { sec = "0" + sec; }
document.clock.stwa.value = ((hour<=9) ? "0"+hour : hour) + " : " + ((min<=9) ? "0" + min : min) + " : " + sec;
if (text == "Start") { document.clock.theButton.value = "Stop "; }
if (text == "Stop ") { document.clock.theButton.value = "Start"; }
if (document.clock.theButton.value == "Start") {
window.clearTimeout(SD);
return true;
}
SD=window.setTimeout("stopwatch();", 1000);
}
function resetIt() {
sec = -1;
min = 0;
hour = 0;
if (document.clock.theButton.value == "Stop ") {
document.clock.theButton.value = "Start";
}
window.clearTimeout(SD);
}
</script>
有人可以帮我让它们并行工作吗?
感谢您的帮助
I am trying to implement a Javascript/PHP/AJAX clock into my website so that I can have a simple clock which can operate in different timezones (tutorial is here http://networking.mydesigntool.com/viewtopic.php?tid=373&id=31)
This itself works fine, but I already have a javascript stopwatch running on the page, and the 2 seem to clash and the clock won't display while the stopwatch is working.
This is the script for the clock:
<script type="text/javascript">
function loadTime ()
{
http_request = false;
if(window.XMLHttpRequest)
{
// Mozilla, Safari,...
http_request = new XMLHttpRequest();
if(http_request.overrideMimeType)
{
// set type accordingly to anticipated content type
//http_request.overrideMimeType('text/xml');
http_request.overrideMimeType('text/html');
}
}
else if(window.ActiveXObject)
{ // IE
try
{
http_request = new ActiveXObject("Msxml2.XMLHTTP");
}
catch (e)
{
try
{
http_request = new ActiveXObject("Microsoft.XMLHTTP");
}
catch(e)
{
}
}
}
var parameters = "time=";
http_request.onreadystatechange = alertContents;
http_request.open('POST', 'time.php', true);
http_request.setRequestHeader("Content-type", "application/x-www-form-urlencoded");
http_request.setRequestHeader("Content-length", parameters.length);
http_request.setRequestHeader("Connection", "close");
http_request.send(parameters);
}
function alertContents()
{
if (http_request.readyState == 4)
{
if (http_request.status == 200)
{
result = http_request.responseText;
document.getElementById('clock').innerHTML = result;
}
}
}
</script>
<body onload="setInterval('loadTime()', 200);">
and this is the code for the stopwatch:
<script type="text/javascript">
window.onload = function()
{
stopwatch('Start');
}
var sec = 0;
var min = 0;
var hour = 0;
function stopwatch(text) {
sec++;
if (sec == 60) {
sec = 0;
min = min + 1;
} else {
min = min;
}
if (min == 60) {
min = 0;
hour += 1;
}
if (sec<=9) { sec = "0" + sec; }
document.clock.stwa.value = ((hour<=9) ? "0"+hour : hour) + " : " + ((min<=9) ? "0" + min : min) + " : " + sec;
if (text == "Start") { document.clock.theButton.value = "Stop "; }
if (text == "Stop ") { document.clock.theButton.value = "Start"; }
if (document.clock.theButton.value == "Start") {
window.clearTimeout(SD);
return true;
}
SD=window.setTimeout("stopwatch();", 1000);
}
function resetIt() {
sec = -1;
min = 0;
hour = 0;
if (document.clock.theButton.value == "Stop ") {
document.clock.theButton.value = "Start";
}
window.clearTimeout(SD);
}
</script>
Could someone help me get them to work side-by-side please?
Thanks for any help

其一,您在 HTML 中声明了一个
onload
事件处理程序:该处理程序因此在脚本中被覆盖:
这意味着原始的
onload
调用永远不会执行。您应该尝试使用
addEventListener
这样您就可以添加多个同一事件的事件处理程序。还有几点:
setInterval
和setTimeout
,只需传递函数本身。更高效、更不易出错:setInterval(loadTime, 200);
For one, your’re declaring an
onload
event handler in your HTML:which is consequently overwritten in script:
This means the original
onload
call is never executed.You should try using
addEventListener
so you can add multiple event handlers to the same event.A couple more points:
setInterval
andsetTimeout
, just pass the function itself. More efficient and less error-prone:setInterval(loadTime, 200);
试试这个:
请注意微妙的“+=”而不是“=”!
Try this:
See the subtle '+=' instead of '=' !
