I'm loading the page content without refresh using this code
我正在使用此代码加载页面内容而不刷新
<script>
$(document).ready(function(){
//set trigger and container
var trigger = $('#nav ul li a'),
container = $('#container');
//do on click
trigger.on('click', function(e){
/***********/
e.preventDefault();
//get the link location that was clicked
pageurl = $(this).attr('href');
//to change the browser URL to th if(pageurl!=window.location){
window.history.pushState({path:pageurl},'',pageurl+'.php');
/* reload content without refresh */
//set loading img
$('#container').append('<div id = "loading">WAIT... <img src = "img/ajax-loader-small.gif" alt="Currently loading" /></div>');
//change img location to center
$("#loading").css({"position": "absolute", "left": "50%", "top": "50%"});
//get the trigger to reload the contents
var $this = $(this),
target = $this.data('target');
container.load(target + '.php');
});
});
// fix url in the browser when click on backward and foreword arrows
$(window).bind('popstate', function() {
$.ajax({url:location.pathname+'?rel=tab',success: function(data){
$('#container').html(data);
}});
});
</script>
Then I'm trying to get the id value and send it to another page using ajax, since there's no refresh.
然后我试图获取id值并使用ajax将其发送到另一个页面,因为没有刷新。
<li><a href="#"><strong>CATEGORY</strong><span> MENU ELEMENTS</span></a>
<ul class="sub-menu">
<li><a id="id_1" data-target='post_category'>Sub_1</a></li>
<li><a id="id_2" data-target='post_category'>Sub_2</a></li>
<li><a id="id_3" data-target='post_category'>Sub_3</a></li>
<li><a id="id_4" data-target='post_category'>Sub_4</a></li>
<li><a id="id_5" data-target='post_category'>Sub_5</a></li>
<li><a id="id_6" data-target='post_category'>Sub_6</a></li>
<li><a id="id_7" data-target='post_category'>Sub_7</a></li>
</ul>
</li>
JQuery code
JQuery代码
<script>
$(document).on("click","a",function(e){
$.ajax({
url: "post_category.php",
type: "POST",
data: $(this).attr("id")
});
});
</script>
php code in the other page
其他页面中的PHP代码
<?php
if(isset($_POST['id'])){
echo 'Worked';
} else {
echo 'No data';
}
the jquery take the id successfully, but it didn't send the data to the required page correctly so it always unset and I get No data in the else condition. I tried everything, but nothing worked. Please help.
jquery成功获取了id,但它没有正确地将数据发送到所需的页面,因此它总是未设置,并且在else条件下我得到No data。我尝试了一切,但没有任何效果。请帮忙。

The problem looks to be in the data you are trying to post. You need to post a valid JSON object.
问题似乎出现在您要发布的数据中。您需要发布有效的JSON对象。
Make sure you construct a valid javascript object and then use the JSON.stringify
function to convert your javascript object into an JSON object.
确保构造有效的javascript对象,然后使用JSON.stringify函数将javascript对象转换为JSON对象。
Set your id using $(this)
outside of your $.ajax
call to reference the anchor element instead of the $.ajax
object.
在$ .ajax调用之外使用$(this)设置你的id来引用anchor元素而不是$ .ajax对象。
Something like the following should give you the desired result:
像下面这样的东西应该给你想要的结果:
<script>
$('a').on("click", function (e) {
var id = $(this).attr("id");
$.ajax({
url: "post_category.php",
type: "POST",
data: JSON.stringify({
id: id
})
});
});
</script>

Need to send data in key-value pair, so that you can access them by key in the other page. Also this is referring to the document and thus $(this).attr('id') is null. You can try the below code as shown:
需要以键值对方式发送数据,以便您可以通过其他页面中的键访问它们。这也是指文档,因此$(this).attr('id')为null。您可以尝试以下代码,如下所示:
<script>
$(document).on("click","a",function(e){
var element =e.target;
$.ajax({
url: "post_category.php",
type: "POST",
data: {'id':$(element).attr("id")}
});
</script>

$.ajax({
url: "post_category.php",
type: "POST",
data: {id:$(this).attr("id")}
});
});
Try this you were missing id:(this).attr("id")
试试这个你缺少id :(这个).attr(“id”)
