[英]How to get a value back to my ajax result from a PHP file
I am making a post to a php file like this: 我正在向这样的php文件发布帖子:
$( document ).ready(function() {
$(document).on('click', '.menulistnaam', function (){
var menucatnaam = $(this).attr('id');
$.post("include/menuinclude.php?menucat="+menucatnaam, function(result){
$("#menukaart").html(result);
});
});
});
All works fine but I would like to send a specific result back to this code. 一切正常,但我想将特定结果发送回此代码。
In my PHP I have the following: 在我的PHP中,我有以下内容:
$menucatnaam = $_GET['menucat'];
$menu = "
select
cnt.catid, cat.id, cnt.title, cnt.introtext, cnt.fulltext, cnt.ordering, cnt.images, cnt.alias, cnt.state, f.item_id, cat.id, cat.title,
max(case when f.field_id = 8 then f.value end) as nieuw,
max(case when f.field_id = 7 then f.value end) as beschrijving,
max(case when f.field_id = 5 then f.value end) as prijs,
max(case when f.field_id = 4 then f.value end) as inhoud,
max(case when f.field_id = 3 then f.value end) as media
from snm_fields_values f
join snm_content cnt
on cnt.id = f.item_id
join snm_categories cat
on cnt.catid = cat.id
where cnt.state = 1
and cat.alias = '".$menucatnaam."'
group by f.item_id
order by f.item_id, media, beschrijving, prijs, inhoud, nieuw
";
How can I send back the value of $menucatnaam
? 如何寄回$menucatnaam
的价值?
In the end I want to check what anchor tag was clicked and give it an active
class. 最后,我想检查单击了哪个锚标记并为其提供active
类。
I googled a bit and found out I had to create an array and then encode it with json but I couldn't get it to work. 我用谷歌搜索了一下,发现我必须创建一个数组,然后用json对其进行编码,但是我无法使其工作。
My attempt was this: 我的尝试是这样的:
$aliasjson = json_encode(array("aliasresult"=>"$menucatnaam"));
echo $aliasjson;
And then my js: 然后我的js:
$.post('include/menuinclude.php', {"menucat": menucatnaam}, function (result) {
$("#menukaart").html(result);
console.log(result.aliasresult);
}, 'json');
But that didn't give me the result I wanted at all, when I clicked an anchor tag nothing was happening. 但这根本没有提供我想要的结果,当我单击锚标记时,什么也没有发生。
How can I do this? 我怎样才能做到这一点?
In ajax call add below parameter 在ajax调用中添加以下参数
dataType: "json",//tells jQuery that you want it to parse the returned JSON
and after getting response 得到回应后
result = jQuery.parseJSON(result);//parsing JSON to string
console.log(result.result);
or else don't change any jquery code just echo required paramter from PHP 否则不要更改任何jquery代码,只是从PHP回显所需的参数
echo $menucatnaam;
