[英]ajax request to the server side script (controller) to get the status of the server
I want to get a server side response for a button in a twig page.我想获得树枝页面中按钮的服务器端响应。 As a example - there will be 2 button in the page ---例如 - 页面中将有 2 个按钮 ---
ON/OFF开关
When the page load it should check from server (check from elasticsearch database) whether it returns True or false, for both button.当页面加载时,它应该从服务器检查(从 Elasticsearch 数据库检查)是否返回 True 或 false,对于两个按钮。
So for instanse we say that for ON button it return "True" it should change it color to green, like ----因此,例如我们说对于 ON 按钮它返回“True”它应该将其颜色更改为绿色,例如----
$(this).addClass('btn-success');
$(this).removeClass('btn-primary');
The main purpose is to check what's the current status, when the page load.主要目的是检查页面加载时的当前状态。
So this is not a on-click function, because it show show the status when the page is loaded.所以这不是点击功能,因为它显示页面加载时的状态。
This is my client side code ---这是我的客户端代码---
$(document).ready(function(){
//send the request with empty data to the server to check the status
$.post('/url/to/action', {}, function(msg){
// we return a response like {status: 'on'} to the client if the search is on
if (msg.status == 'on'){
$('#my-button').addClass('success');
}
// else it is disabled
else
$('#my-button').addClass('primary');
});
});
this is the integration with my symfony application ---这是与我的 symfony 应用程序的集成 ---
public function getStatusAction(Request $request){
if ($output = !null) {
return new \Symfony\Component\HttpFoundation\JsonResponse(array('status' => 'on'));
} else {
return new \Symfony\Component\HttpFoundation\JsonResponse(array('status' => 'off'));
}
}
This is the status when i run to get the status这是我跑去获取状态时的状态
Now the problem is when the page is loading it is not rerurning the status for the button.现在的问题是当页面加载时它没有重新显示按钮的状态。 I mean if the "status == 'on'" the button should be green instead of primary.我的意思是如果“状态 == 'on'”按钮应该是绿色而不是主要的。
Do anyone knows how i can fix this problem.有谁知道我如何解决这个问题。
to make that, you can use setInterval
要做到这一点,您可以使用setInterval
function refreshStatus () {
$.post('/url/to/action', {}, function (msg) {
// we return a response like {status: 'on'} to the client if the search is on
if (msg.status == 'on'){
$('#my-button').addClass('success');
}
// else it is disabled
else
$('#my-button').addClass('primary');
});
}
refreshStatus(); // call on page load
setInterval(refreshStatus, 5000); // call refreshStatus every 5 seconds
