我试图根据div / form的输入值显示php文件的结果。
我有以下JavaScript：
<script>
$(document).ready(function(){
$('#ranksubmit').click(function() {
$.ajax({
type: "post",
url: "queryrankings.php",
data: $("#query-form").serialize(),
success: function(result){
$(".results-table").html(result);
}
});
//return false;
});
});
</script>
它应该将此div的值传递给php脚本queryrankings.php：
<div class="form-horizontal" id="query-form" >
<fieldset>
<!-- Form Name -->
<legend class = "text-center">Query Rankings<hr></legend>
<!-- Multiple Radios (inline) -->
<div class="form-group">
<label class="col-md-4 control-label" for="ranktype">Ranking Type:</label>
<div class="col-md-4">
<label class="radio-inline" for="ranktype-0">

当我尝试$_POST php脚本中的值时，它不起作用。不应该读取这个div中的值吗？
这是php。它将返回一个常规的print语句，但它不会打印我假设的已发布变量，因为它没有读取任何内容：
<?php
$dbHost = "localhost";
$dbUsername = "user_rw";
$dbPassword = "";
$dbName = "webdb";
// Create connection
$db = new mysqli($dbHost, $dbUsername, $dbPassword, $dbName);
// Check connection
if ($db->connect_error) {
die("Connection failed: " . $db->connect_error);
} else {
$type = $_POST['ranktype'];
print $type;
}
?>
我使用的是<div>而不是<form>，因为我不想在点击提交按钮时重新加载页面。
答案 0 :(得分：0)
<div class="form-horizontal" id="query-form" > ...</div>
应为form tag
<form class="form-horizontal" id="query-form" > .... </form>
<强>更新
$('#ranksubmit').click(function(e) {
e.preventDefault()
// the rest of the code
});
使用<input type="button"/>或e.preventDefault()或return false阻止表单提交。
