好吧所以我忙于一个php
代码,当我点击插入按钮时,我希望显示值而不重新加载页面。
这是我的代码:
<?php
$connection = mysqli_connect('localhost', 'root', '', 'universitynew');
$sql="SELECT * FROM tblstudent";
$student_records=mysqli_query($connection,$sql);
?>
<html>
<head>
<title></title>
<link rel="stylesheet" type='text/css' href="bootstrap.min.css" />
<script type='text/javascript' src="bootstrap.min.js"></script>
<script type='text/javascript' src="jquery.min.js"></script>
</head>
<body>
<a href="Student.php"class="btn btn-primary active" role="button">Student table</a>
<a href="Degree.php"class="btn btn-primary" role="button">Degree table</a>
<a href="Subject.php"class="btn btn-primary" role="button">Subject table</a>
<a href="assessment.php"class="btn btn-primary" role="button">Assessment table</a>
<a href="student_assessments.php"class="btn btn-primary" role="button">Student Assessment table</a>
<a href="Degree_student.php" class="btn btn-primary" role="button">Student Degree table</a>
<a href="Student_Subject.php"class="btn btn-primary" role="button">Student Subject table</a>
<hr></hr>
<table width="800" border="1" cellpadding="1" cellspacing="1">
<input type="button" name="insertrecords" id="insertrecords" value="Insert Records" />
<span id="success" style="display: none">Successfully Inserted</span>
<div id="response"></div>
<script type="text/javascript">
$(document).ready(function () {
$("#insertrecords").click(function () {
$("#success").show();
$.ajax({
url: "insert_student.php",
type: 'POST',
data: {'action':'submit'},
dataType: 'json',
success: function (data) {
$("#success").hide();
if(data.status=="true"){
$("#response").html(data.universitynew);
}else{
$("#response").html("Error in db query");
}
}
});
});
});
</script>
<h1><a href="insert_student.php".php" class="btn btn-info" role="button">Delete Students</a></h1>
<h1><a href="insert_student.php".php" class="btn btn-info" role="button">Update Students</a></h1>
<tr>
<th>Student ID</th>
<th>Student number</th>
<th>Student name </th>
<th>Student surname</th>
<th>Student course</th>
</tr>
<?php
while ($student=mysqli_fetch_assoc($student_records)){
echo"<tr>";
echo"<td>".$student['student_id']."</td>";
echo"<td>".$student['student_number']."</td>";
echo"<td>".$student['student_name']."</td>";
echo"<td>".$student['student_surname']."</td>";
echo"<td>".$student['student_course']."</td>";
echo"</tr>";
}
?>
我设法为显示成功插入的按钮执行了一些jquery
和ajax,并且它确实插入到我的数据库中,通过显示表而不重新加载页面来产生问题。有人可以帮我这么做吗?

您可以使用jQuery中的show函数执行此操作:
$('#success').show();
有关详细指南,请查看以下内容:http://api.jquery.com/show/
编辑: 刚刚看到你正在使用该函数,你的问题是你在请求成功时使用hide,如果失败则需要使用它。
$("#insertrecords").click(function () {
var request = $.ajax({
url: "insert_student.php",
type: 'POST',
data: {'action':'submit'},
dataType: 'json'
});
request.done(function(data){
$("#success").show();
$("#response").html(data.universitynew);
});
request.fail(function(error){
$("#response").html("Error in db query");
});
}

当ajax完成后,您需要显示#success
元素。该元素通过值为none
的CSS显示属性隐藏。您只需将显示属性更改为block
,以便在ajax成功时可见:
$('#success').css("display","block");
您还可以通过jquery show()
函数
$('#success').show();
您可以在此处找到更多信息:http://api.jquery.com/css/
编辑:
$.ajax({
url: '/path/to/file',
type: 'default GET (Other values: POST)',
dataType: 'default: Intelligent Guess (Other values: xml, json, script, or html)',
data: {param1: 'value1'},
})
.done(function() {
$("#success").show(); // this will show the message
...
})
.fail(function() {
...
});
