js调用php函数的方法：jQuery.ajax({
type: "POST",
url: 'your_functions_address.php',
dataType: 'json',
data: {functionname: 'add', arguments: [1, 2]},
success: function (obj, textstatus) {
if( !('error' in obj) ) {
yourVariable = obj.result;
}
else {
console.log(obj.error);
}
}});
您的_function_address.php如下所示：<?php
header('Content-Type: application/json');
$aResult = array();
if( !isset($_POST['functionname']) ) { $aResult['error'] = 'No function name!'; }
if( !isset($_POST['arguments']) ) { $aResult['error'] = 'No function arguments!'; }
if( !isset($aResult['error']) ) {
switch($_POST['functionname']) {
case 'add':
if( !is_array($_POST['arguments']) || (count($_POST['arguments']) < 2) ) {
$aResult['error'] = 'Error in arguments!';
}
else {
$aResult['result'] = add(floatval($_POST['arguments'][0]), floatval($_POST['arguments'][1]));
}
break;
default:
$aResult['error'] = 'Not found function '.$_POST['functionname'].'!';
break;
}
}
echo json_encode($aResult);?>
