我搜索过StackOverFlow,但没找到我要找的东西,所以我发布了我想问你的内容。
我是PHP世界的新来者我是如何开始编写一个脚本来获取数据并在WAP界面上显示那部分是好的我的问题出现在我正在编写的部分中数据插入页面或管理员页面。我已经完成了所有工作,但我很想知道如何使用AJAX来显示一条消息,而不是去特定的处理页面。
Process Page,
<?php
include ('connect.php');
$data = ("SELECT * FROM poiinfo");
$poiName = $_REQUEST['Name'];
$poiDes = $_REQUEST['Descrip'];
$poiCon = $_REQUEST['ConInfo'];
/*$poiImg = $_REQUEST['Image']; */
$dbData = "INSERT INTO poiinfo(`Name`, `Des.`, `Contact`) VALUES ('$poiName','$poiDes','$poiCon')";
$putData = mysql_query($dbData);
if ($putData){
echo "Data inserted";
}else {
echo "Not Done";
}
?>
我可以知道如何使用AJAX来获取消息。
我已经使用了你们给我的代码示例,但我仍然没有完成工作,请你能帮助我找到我做错的事。

使用jQuery的$.ajax
:
$.ajax({
url: "process.php",
type: "POST",
data : { Name : 'John', Descrip : 'some description..', ConInfo : 'some info...' },
success : function(data){
if(data == "Data inserted")
{
console.log("Success!");
}
else
{
console.log("fail!");
}
}
});

这是另一种不使用jquery的解决方案。
<强>的index.html 强>
<head>
<script type="text/javascript" src="test.js"></script>
</head>
<body>
<!-- reply from process.php is shown in this div -->
<div id=message></div>
<!-- click to send data -->
<a href="#" onclick="sendData('John','student','no more info')"> click here </a>
</body>
</html>
<强> test.js 强>
function sendData(Name,description,info) {
var ajaxRequest; // The variable that makes Ajax possible!
try{
// Opera 8.0+, Firefox, Safari
ajaxRequest = new XMLHttpRequest();
}
catch (e)
{
// Internet Explorer Browsers
try
{
ajaxRequest = new ActiveXObject("Msxml2.XMLHTTP");
}
catch (e)
{
try
{
ajaxRequest = new ActiveXObject("Microsoft.XMLHTTP");
}
catch (e)
{
// Something went wrong
alert("Your browser broke!");
return false;
}
}
}
// Create a function that will receive data sent from the server
ajaxRequest.onreadystatechange = function()
{
var ajaxDisplay = document.getElementById('message');
if(ajaxRequest.readyState == 4)
{ ajaxDisplay.innerHTML = ajaxRequest.responseText;}
else { document.getElementById('message').innerHTML="<span style=\"color:green;\">Loading..</span>"; }
}
var url="process.php?name="+Name+"&Descrip="+description+"&ConInfo="+info;
ajaxRequest.open("POST", url, true);
ajaxRequest.send(null);
}

你也可以这样做。
您的HTML
<label>Name</labe><input type="text" id="name" name="full_name" value="" />
<label>Address</labe><input type="text" id="addr" name="addr" value="" />
<input type="button" name="save" id="save_data" value="Save" />
添加jQuery之后在头部分中的执行类似这样的操作
<script>
$(document).ready(function(){
$("#save_data").click(function(){
var name = $("#name").val();
var addr = $("#addr").val();
var dataString = 'name='+name'&address='+address;
$.ajax({
type:'POST',
data:dataString,
url:'process.php',
success:function(data){
if(data="inserted") {
alert("Insertion Success");
} else {
alert("Not Inserted");
}
}
});
});
});
</script>
“process.php page”
$name = $_POST['name'];
$address = $_POST['address'];
// DO YOUR INSERT QUERY
$insert_query = mysql_query("INSERT QUERY GOES HERE");
if(// CHECK FOR AFFECTED ROWS) {
echo "inserted";
} else {
echo "not";
}
