我正在尝试根据 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>
它应该将这个 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">
<input type="radio" name="ranktype" id="ranktype-0" value="1" checked="checked">

</label>
<label class="radio-inline" for="ranktype-1">
<input type="radio" name="ranktype" id="ranktype-1" value="2">

当我尝试 $_POST php 脚本中的值不起作用。它不应该读入这个 div 中的值吗？
这是 php.ini 文件。它会返回一个常规的打印语句，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;
}
?>我正在使用 <div>而不是 <form>因为我不希望在单击提交按钮时重新加载页面。
最佳答案
<div class="form-horizontal" id="query-form" > ...</div>
应该是form tag
<form class="form-horizontal" id="query-form" > .... </form>
已更新。
$('#ranksubmit').click(function(e) {
e.preventDefault()
// the rest of the code
});
使用 <input type="button"/> , 或 e.preventDefault()或 return false以防止提交表单。
