这是ajax函数
$(document).ready(function() {
$('#submit').click(function(e) {
e.preventDefault();
$.ajax({
type: 'POST',
url: 'searchphp.php',
data: {suburb_id: $('#suburb_id').val()},
success: function(data)
{
$("#tableContent").html(data);
}
});
});
});
这是需要接收数据的php文件,它工作得很完美。
<?php
//Check the form if submit by post
if (isset($_POST["searchBtn"])) {
$strInputSuburb = "";
$strInputSuburb = $_POST["suburb_id"];
//Check if the input box is empty or not
//if BOTH "Suburb" AND "Street" is empty, it will display the error message.
if(!empty($strInputSuburb))
{
//Connect to database server and table
include("connection.php");
@mysqli_select_db($conn, "db")
or die ("Database not available");
$querySql1 = "select * from Infringement
where suburb like '%".mysqli_real_escape_string($conn, $strInputSuburb)."%' and Street1 like '%".mysqli_real_escape_string($conn, $strInputStreet)."%'
order by Suburb, Fines DESC";
$result1 = mysqli_query($conn, $querySql1)
or die ("No information return...");
$count = mysqli_num_rows($result1);
$i=1;
if(!$count==0){
//do stuff, like echo
}
else {
//do stuff
}
//Release the SQL clause
mysqli_free_result($result1);
//Close the connection to database
mysqli_close($conn);
}
else {
//do stuff
}
}
?>
我想加载到这个div
<div id="tableContent"></div>
css样式是
#tableContent {
width:100%;
height:400px;
}
输入框位于
之下<input type="textbox" class="form-control" name="suburb" placeholder="Suburb" id="suburb_id" >
<input type="submit"class="btn" name="searchBtn" id='submit' value="Search" />
我之前使用php从表单中获取数据。使用Ajax后,我删除了“form”标签。
非常感谢你。

您没有发送PHP脚本正在检查的searchBtn
参数。将其添加到data:
选项。
$(document).ready(function() {
$('#submit').click(function(e) {
e.preventDefault();
$.ajax({
type: 'POST',
url: 'searchphp.php',
data: {
suburb_id: $('#suburb_id').val(),
searchBtn: 'Search'
},
success: function(data)
{
$("#tableContent").html(data);
}
});
});
});
或者从PHP脚本中删除该检查,然后测试if (isset($_POST['suburb_id']))
。
