Suppose the current time is 7000 milliseconds. When the time is 3000—6000 is the value of 3000, when the time is 6000—9000 is the value of 6000, that is, the maximum value in the XML is less than the current time

The XML file,

<?xml version="1.0" encoding="utf-8"?>
<catalog>
<cd>
<ID>2</ID>
<title> The first 1 speak </title>
<mediaUrl>123</mediaUrl>
<htmlUrl>1.html</htmlUrl>
<orderNo>2</orderNo>
<StudyTimes>00:00:30</StudyTimes>
<Secondss times="30000">1.html</Secondss>
</cd>
<cd>
<ID>3</ID>
<title> The first 2 speak </title>
<mediaUrl>123</mediaUrl>
<htmlUrl>2.html</htmlUrl>
<orderNo>2</orderNo>
<StudyTimes>00:01:00</StudyTimes>
<Secondss times="60000">2.html</Secondss>
</cd>
<cd>
<ID>4</ID>
<title> The first 3 speak </title>
<mediaUrl>123</mediaUrl>
<htmlUrl>3.html</htmlUrl>
<orderNo>2</orderNo>
<StudyTimes>00:01:30</StudyTimes>
<Secondss times="90000">3.html</Secondss>
</cd>
</catalog>

Javascript:

MediaPlayer. Controls. CurrentPosition * 1000 to the current time

function times() {
//Define array array
var array =new Array();
//Define the xmldom protocol
var xmlDom =new ActiveXObject("Microsoft.XMLDOM");
xmlDom.async =false;
//Load XML file
xmlDom.load(id.value +"_imsmanifest.xml"); // jump
try {
//Find all the Secondss
x = xmlDom.getElementsByTagName("Secondss");
// traverse
for (i =0; i < x.length; i++) {
//Take times attribute
var s = x[i].getAttribute("times");
//If the attribute value is less than the MediaPlayer. Controls. CurrentPosition * 1000 is added to the array
if (s <= MediaPlayer.Controls.CurrentPosition *1000) {
array.push(s);
}
}
//Sorted array the array (array. The length - 1) is less than the MediaPlayer. Controls. CurrentPosition * 1000 the maximum inside
array.sort();
}
