我最初为我的帖子创建了一些过滤器，其中我的functions.php文件将返回html，但是有很多html所以我决定我应该使用JSON将数据传递给jQuery然后从我的输出html js文件。但我现在遇到的问题是，当我将响应输出到控制台时，我只是得到了文本。
例如，我试图让每个帖子永久链接以及我在一个大段落中收到以下内容;
[{"permalink":"http:\/\/websitename.co.uk\/property\/rumballs-court-bishops-stortford-hertfordshire-cm23-copy-2\/"},
{"permalink":"http:\/\/websitename.co.uk\/property\/high-wych-road-sawbridgeworth-hertfordshire-cm21-copy\/"},
{"permalink":"http:\/\/websitename.co.uk\/property\/grovebury-house-galloway-road-bishops-stortford-hertfordshire-cm23-copy\/"},
{"permalink":"http:\/\/websitename.co.uk\/property\/rumballs-court-bishops-stortford-hertfordshire-cm23\/"}]
我不应该只收到一个对象吗？
这是我的代码;
function custom_js_css(){
wp_enqueue_script('all_js', get_template_directory_uri() . '/js/all.min.js', 'jquery', null, true);
wp_enqueue_style('all_css', get_template_directory_uri() . '/css/main.min.css');

如果我使用你在js文件中看到的for循环输出响应，我会得到相同的段落但每行都有一个字符

当你在php页面上回显出json_encoded数组时，它是json对象的字符串表示。您需要将字符串转换为对象。
你可以通过几种方式做到这一点。
在你的js页面上使用：
var data = JSON.parse(response);
console.log(data);
另一种方法是通过声明预期从PHP脚本接收的数据类型来更新你的ajax。见dataType: 'json'
$.ajax({
url: ajax_url,
data: filter.serializeArray(), // form data
//type:filter.attr('method'), // POST
dataType: 'json', //<--This should automatically convert the string to json for you.
success:function(response){
// for(var i = 0; i < response.length; i++){
// console.log(response[i]);
// }
console.log(response);
// $('#response').html(data);
// post_count();
}
});

您正在使用ajax编码的字符串，在使用之前应该进行解析。否则它只是一个刺痛，.so
jQuery(function($){
$('#filters').submit(function(e){
e.preventDefault();
var filter = $('#filters');
$.ajax({
url: ajax_url,
data: filter.serializeArray(), // form data
type: POST
success:function(response){
var data = JSON.parse(responce);
for(var i = 0; i < data.length; i++){
console.log(data[i]);
}
});
});
});
应该工作。
