[英]how to randomly change the src of an iframe from a text file
I want to change the src of an iframe randomly from a text file,so that when a user opens that iframe a different url is opened in iframe.我想从文本文件中随机更改 iframe 的 src,以便当用户打开该 iframe 时,会在 iframe 中打开不同的 url。
<html>
<head>
<script src="http://code.jquery.com/jquery-1.9.1.min.js"></script>
</head>
<body>
<script type="text/javascript">
function read() {
var txtFile = new XMLHttpRequest();
txtFile.open("GET", "https://9to5notes.com/new/add.txt",true);
txtFile.onreadystatechange = function () {
if (txtFile.readyState === 4) {
// Makes sure the document is ready to parse.
if (txtFile.status === 200)
{
var alltext=txtFile.responseText;
var linetext=txtFile.responseText.split("\n");
var delimeter = '^';
var text0= linetext[0];
var splitted = text0.split(delimeter);
console.log(splitted[1]);
$('#iframe1').attr('src', splitted[1]);
}
}
}
txtFile.send(null)
}
$(function(){
read();
});
</script>
<iframe id="iframe1" src="" />
</body></html>
the text file looks like this Site1^ https://www.google.com/ Site2^ https://www.facebook.com/文本文件看起来像这样 Site1^ https://www.google.com/ Site2^ https://www.facebook.com/
First read the text file with PHP首先用PHP读取文本文件
And store URL's into array of JavaScript并将 URL 存储到 JavaScript 数组中
Then with random function place into iframe然后用随机函数放入 iframe
