JSW*_*189 1 html javascript forms radio-button
我正在使用单选按钮对分页结果进行排序。但是，每当单击该按钮并自动提交时，它就会变为未选中状态。我想保持按钮处于选中状态，以便用户知道他们选择了哪一个。我怎样才能做到这一点？
这是我所拥有的：
function autoSubmit() {
var formObject = document.forms['theForm'];
formObject.submit();
}
<input type="radio" name="sort" value="time" onChange="autoSubmit();" />
<input type="radio" name="sort" value="year" onChange="autoSubmit();" />
<input type="radio" name="sort" value="name" onChange="autoSubmit();" />
if(isset($_GET["sort"])) {
$sort = $_GET["sort"];
}

我认为你的代码是这样的：
<?php
$sort = "";
if(isset($_GET["sort"]))
{ $sort = $_GET["sort"]; }
?>
<html>
<head>
<script>
function autoSubmit()
{
var formObject = document.forms['theForm'];
formObject.submit();
}
</script>
</head>
<body>
<form name='theForm' id='theForm'>
<input type="radio" name="sort" <?php if ($sort == 'upload_time') { ?>checked='checked' <?php } ?>value="upload_time" onChange="autoSubmit();" />Recently Uploaded
<input type="radio" name="sort" <?php if ($sort == 'article') { ?>checked='checked' <?php } ?> value="article" onChange="autoSubmit();" /> Alphabetically
<input type="radio" name="sort" <?php if ($sort == 'year') { ?>checked='checked' <?php } ?> value="year" onChange="autoSubmit();" /> Most Recent
</form>
</body>
