我想通过AJAX插入数据(没有重新加载页面)。我试过但它没有显示数据,也没有重新加载页面。
我有一个文件 first.php (其中包含表单),一个AJAX代码和一个 firstcall.php ,其中将执行查询。
我的 first.php (html表单)是:
<form class="reservation-form mb-0" action="" method="post" autocomplete="off">
<input name="name1" id="name1" class="form-control" type="text" placeholder="Enter Name" required aria-required="true">
<input name="age" id="age" class="form-control" required type="number" placeholder="Enter Age" aria-required="true">
<input type="checkbox" id="checkbox" class="checkbox1" name="namec[]" value="<?php echo $value['id']; ?>" >
<input type="submit" class="pull-right btn btn-warning" value="Submit" id="submit">
</form>
此处应显示数据:
<div class="col-md-5">
<div class="panel panel-primary" id="showdata">
</div>
</div>
AJAX是:
<script type="text/javascript">
$(document).ready(function(){
$("#submit").click(function(){
var name1 = $("#name1").val();
var age = $("#age").val();
var chkArray=[];
$('.checkbox1:checked').each( function() {
chkArray.push($(this).val());
} );
var selected;
selected = chkArray.join(',') ;
if(selected.length > 1){
$.ajax( {
url:'firstcall.php',
type:'POST',
data:{name1: name1,age: age,namec: chkArray},
}).done(function(data){
$("#showdata").html(data);
});
}
else{
alert("Please at least one of the checkbox");
}
}
}
</script>
firstcall.php 是:
<div class="panel panel-primary" id="showdata">
<?php
foreach($_POST['namec'] as $selected){
echo $selected;
$_SESSION['name1']=$_POST["name1"];
$_SESSION['age']=$_POST["age"];
echo $name1=$_SESSION['name1'];
echo $age=$_SESSION['age'];
$query=mysql_query("insert into patient_details (p_name,p_age,g_number) values ('$name1','$age','$selected')") or die(mysql_error());
}
?>

$("#submit").click(function(event){
添加命令后
event.preventDefault();
您的页面不会重新加载

提交按钮会在点击时自动重新加载页面,因此解决方案是将按钮类型更改为button
或将preventDefault
添加到点击事件
$("#submit1,#submit2").click(function() {
alert('form submited')
})
$("#submit3").click(function(e) {
e.preventDefault();
alert('form submited')
})
