Php 帮助停止设置间隔
我不太清楚如何设置这个。我试着做互联网告诉我的事Php 帮助停止设置间隔,php,javascript,Php,Javascript,我不太清楚如何设置这个。我试着做互联网告诉我的事 <?php function animateFunds($startAmount, $finishAmount) { echo '<div id="fundage" style="display:inline;"> '; echo number_format($startAmount, 2, '.', ',') . ' </div>'; //we are shooting for abou

//we are going to cover, and figure out the
//setInterval delay for JS
$distanceInPennies = ($finishAmount - $startAmount) * 100;
//5 secs in MS = 5000
$delay = 5000 / $distanceInPennies;
//round $delay
$delay = floor($delay);
//delay no less than 5 ms
if($delay < 5) $delay = 5;
/// countdown JS
echo '<script type="text/javascript">
var thisFunc = setInterval(function () {

var currentFund = document.getElementById("fundage").innerHTML;
currentFund = parseFloat(currentFund);
// add a penny
currentFund += 0.01;
// round to 2 decimal places
currentFund = Math.round(currentFund * 100)/100;
// dont update more than finish amount
if(currentFund > ' . $finishAmount . ') currentFund = ' . $finishAmount . ';

如果您在setInterval中声明了一个动态函数,那么在该函数中对clearInterval的调用将无法访问thisFunc变量 尝试在setInterval范围之外声明函数,如下所示:
/// countdown JS
echo '<script type="text/javascript">
function doTimer() {
//instantiate delay
//delay = ' . $delay . ';
// get current fundage
var currentFund = document.getElementById("fundage").innerHTML;
currentFund = parseFloat(currentFund);
// add a penny
currentFund += 0.01;
// round to 2 decimal places
currentFund = Math.round(currentFund * 100)/100;
// dont update more than finish amount
if(currentFund > ' . $finishAmount . ') currentFund = ' . $finishAmount . ';
//if finish amount reached, stop function
if(currentFund = ' . $finishAmount . ') clearInterval(thisFunc);
// update countdown div
document.getElementById("fundage").innerHTML = currentFund;
}
var thisFunc = setInterval("doTimer()", ' . $delay . ');
</script>';
你想做什么,什么不起作用?唯一的问题是让JS函数停止。我想我应该用一个变量名来标记整个事件,然后在这个变量上使用clearInterval。var thisFunc=setIntervalfunction{…和ifcurrentFund='.$finishAmount.'clearIntervalthisFunc;但我猜不是,因为这不起作用
