英文:
Send a keyup event to a child window without changing source of the child
问题
我有两个页面，像这样
test.html
<!DOCTYPE html>
<html>
<head>
<title>Test</title>
</head>
<body>
</body>
</html>
<script src="https://code.jquery.com/jquery-3.7.0.min.js"></script>
<script>
$(document).ready(function(){
var w=window.open("search.html","_blank");
w.onload = function(){
setTimeout(() => {
$('#search', w.document).val("test");
$('#search', w.document).trigger("keyup");
}, 5000);
}
});
</script>
和 search.html
<!DOCTYPE html>
<html>
<head>
<title>Search</title>
</head>
<body>
<input type="text" id="search">
</body>
</html>
<script src="https://code.jquery.com/jquery-3.7.0.min.js"></script>
<script>
$(document).ready(function(){
$("#search").keyup(function(){
alert($(this).val());
});
});
</script>
当test.html成功加载时，它会打开一个名为search.html的窗口，并将搜索值设置为"test"，然后触发keyup事件。但只有设置值能够生效，无法触发keyup事件。请帮我检查一下

I have two page like this
test.html
<!DOCTYPE html>
<html>
<head>
<title>Test</title>
</head>
<body>
</body>
</html>
<script src="https://code.jquery.com/jquery-3.7.0.min.js"></script>
<script>
$(document).ready(function(){
var w=window.open("search.html","_blank");
w.onload = function(){
setTimeout(() => {
$('#search', w.document).val("test");
$('#search', w.document).trigger("keyup");
}, 5000);
}
});
</script>
and search.html
<!DOCTYPE html>
<html>
<head>
<title>Search</title>
</head>
<body>
<input type="text" id="search">
</body>
</html>
<script src="https://code.jquery.com/jquery-3.7.0.min.js"></script>
<script>
$(document).ready(function(){
$("#search").keyup(function(){
alert($(this).val());
});
});
</script>
When test.html load success, it open window search.html and set search value is test and send event keyup to it. But only set value can happen, keyup cannot send.
Please check for me

将代码注入子窗口中；
<!DOCTYPE html>
<html>
<head>
<title>测试</title>
</head>
<body>
</body>
</html>
<script src="https://code.jquery.com/jquery-3.7.0.min.js"></script>
<script>
$(document).ready(function () {
var w = window.open("search.html", "_blank");
w.onload = function () {
setTimeout(() => {
$('#search', w.document).val("test");
$(`<script>$("#search").trigger('keyup');</script>`).appendTo(w.document.head);
}, 5000);
}
});
</script>
英文:
Inject the code into the child window;
<!DOCTYPE html>
<html>
<head>
<title>Test</title>
</head>
<body>
</body>
</html>
<script src="https://code.jquery.com/jquery-3.7.0.min.js"></script>
<script>
$(document).ready(function () {
var w = window.open("search.html", "_blank");
w.onload = function () {
setTimeout(() => {
$('#search', w.document).val("test");
$(`<script>$("#search").trigger('keyup');<\/script>`).appendTo(w.document.head);
}, 5000);
}
});
</script>
