如何使用ajax执行PHP函数?我的脚本页面上有多个函数,但我想调用一个函数。
<?php
function one(){return 1;}
function two(){return 2;}
?>
$("#form").on('submit',(function(e){
e.preventDefault();
$.ajax({
url: "process.php",
type: "POST",
data: new FormData(this),
contentType: false,
cache: false,
processData:false,
success: function(response){
alert(response);
}
});
}));
<script src="http://code.jquery.com/jquery-1.9.1.js"></script>
<form action="" method="POST" id="form">
<input type="text" name="text" id="text" />
<button type="submit" id="submit">Upload</button>
</form>
使用 Get param "action"
$("#form").on('submit', (function(e) {
e.preventDefault();
$.ajax({
url: "process.php?action=one",
type: "POST",
data: new FormData(this),
contentType: false,
cache: false,
processData: false,
success: function(response) {
alert(response);
}
});
}));
<script src="http://code.jquery.com/jquery-1.9.1.js"></script>
<form action="" method="POST" id="form">
<input type="text" name="text" id="text" />
<button type="submit" id="submit">Upload</button>
</form>
然后在您的过程中.php文件中,只需捕获"动作"
function one(){
return 1;
}
function two(){
return 2;
}
if ( isset($_GET['key']) && !empty(isset($_GET['key'])) ) {
$action = $_GET['key'];
switch( $action ) {
case "one":{
return 1; // or call here one();
}break;
case "two":{
return 2; // or call here two();
}break;
default: {
// do not forget to return default data, if you need it...
}
}
}
您可以通过 AJAX 调用和 PHP 代码中的一些更改,通过 AJAX 调用 PHP 代码的特定函数。
例如:阿贾克斯:
$.ajax({
url: "yourphpfile.php",
data: "function=one", // or function=two if you want the other to be called
/* other params as needed */
});
然后在 yourphpfile .php 代码中,
<?php
function one(){return 1;}
function two(){return 2;}
if(isset($_GET['function'])) {
if($_GET['function'] == 'one') {
function one() // call function one
} elseif($_GET['function'] == 'two') {
//function two() // call function two
}
}
?>
