我正在尝试将 Jquery 与 json 一起使用，并通过用类警报替换 DIV 来返回结果。 我也知道JS使用警报，所以我稍后会改变它。
但是我有点卡在这里，它确实发布到秒文件（offerte2.php），但没有显示任何结果。
我不确定这是java还是php的错误。有人有一些想法吗？
脚本.js：
$(document).ready(function() {
var form = $('#form');
var submit = $('#submit1');
var page1 = $('.page1');
form.on('submit', function(e) {
e.preventDefault();
$.ajax({
url: '******/shop/templates/Euphoria-Art/offerte2.php', // form action url
type: 'post', // form submit method get/post
dataType: 'json', // request type html/json/xml
data: form.serialize(), // serialize form data
beforeSend: function() {
page1.fadeOut();
},
success: function(result) {
if(result.error){
page1.html(result.html).fadeIn();
console.log(e)
}else{
page1.html(result.html).fadeIn();
form.trigger('reset');
}
}
});
});
});
捕获值
<?php
header('Content-Type: application/json');
if( isset( $_SERVER['HTTP_X_REQUESTED_WITH'] ) ){
$class1 = filter_var($_POST['class1'], FILTER_SANITIZE_STRING);
$class2 = filter_var($_POST['class2'], FILTER_SANITIZE_STRING);
$class3 = filter_var($_POST['class3'], FILTER_SANITIZE_STRING);
$class4 = filter_var($_POST['class4'], FILTER_SANITIZE_STRING);
$class5 = filter_var($_POST['class5'], FILTER_SANITIZE_STRING);
$result = array("error" => false, "html" => null);
$totaal1 = $class1 + $class2 + $class3 + $class4 + $class5
$result["error"] = false;
$result["html"] = "<h3>Het totaal is .$totaal1.</h3>";
echo json_encode($result);
exit;
}
?>
一切
似乎都很好，除非你在$class5之后错过了一个分号
$totaal1 = $class1 + $class2 + $class3 + $class4 + $class5;
if( isset( $_SERVER['HTTP_X_REQUESTED_WITH'] ) ){
$class1 = filter_var($_POST['class1'], FILTER_SANITIZE_STRING);
$class2 = filter_var($_POST['class2'], FILTER_SANITIZE_STRING);
$class3 = filter_var($_POST['class3'], FILTER_SANITIZE_STRING);
$class4 = filter_var($_POST['class4'], FILTER_SANITIZE_STRING);
$class5 = filter_var($_POST['class5'], FILTER_SANITIZE_STRING);
$result = array("error" => false, "html" => null);
$totaal1 = $class1 + $class2 + $class3 + $class4 + $class5;
$result["error"] = false;
$result["html"] = "<h3>Het totaal is .$totaal1.</h3>";
} else {
$result["error"] = true;
$result["html"] = "<h3>Error</h3>";
}
echo json_encode($result);
exit;
