Is it possible to check timeout on jQuery.post()?
提问by horgen
I have this code requesting some folder info from a mysql DB:
我有这个代码从 mysql 数据库请求一些文件夹信息：
function gotoDir(pmcat_id, pcat_id){
$('#slideshowContainer').html('<img class="loader" src="/javascript/ajax-loader.gif">');
$.post("/publish/includes/content.includes/functions.slideshow.php",
{ updateSlideshowDir: 1, pmcat_id: pmcat_id, pcat_id: pcat_id },
function(data){
$('#pageSlideshow').html(data.content);
}, "json"
);
}
Sometimes the post request times out because of bad internet connection. Is it possible to set a timeout check on $.post() ? Ex: if $.post() uses more then X ms, reload the request.
有时，由于互联网连接不良，发布请求超时。是否可以对 $.post() 设置超时检查？例如：如果 $.post() 使用的时间超过 X 毫秒，则重新加载请求。
UPDATE: Looks like I found a solution:
更新：看起来我找到了一个解决方案：
function gotoDir(pmcat_id, pcat_id){
$('#slideshowContainer').html('<img class="loader" src="/javascript/ajax-loader.gif">');
$.ajax({
type:"post",
url:"/publish/includes/content.includes/functions.slideshow.php",
data: { updateSlideshowDir: 1, pmcat_id: pmcat_id, pcat_id: pcat_id },
dataType: "json",
success:function(data) {
if (data == null){
alert('ajax failed. reloading...');
gotoDir(pmcat_id, pcat_id);
} else {
$('#pageSlideshow').html(data.content);
}
}
});
}
Is this a OK way to do this? :S
这是一个好的方法吗？:S

$.ajax has all the functions you need to accomplish what you are asking for:
$.ajax 具有完成您所要求的所有功能：
function gotoDir(pmcat_id, pcat_id) {
$('#slideshowContainer').html('<img class="loader" src="/javascript/ajax-loader.gif">');
$.ajax({
type: "POST",
url: "/publish/includes/content.includes/functions.slideshow.php",
data: { updateSlideshowDir: 1, pmcat_id: pmcat_id, pcat_id: pcat_id },
dataType: "json",
timeout: 500, // in milliseconds
success: function(data) {
// process data here
},
error: function(request, status, err) {
if(status == "timeout") {
gotoDir(pmcat_id, pcat_id);
}
}
});
}
Please note that you don't need to set the timeoutoption unless you want to trigger the error method after a specific time youwant to set.
请注意，您不需要设置超时时间，除非你想有一个特定的时间后触发错误方法选择你想要设置。

You should use $.ajax()and $.ajaxError(), then with "ajaxComplete" you can check if your request timedout, or succeded.
您应该使用$.ajax()and $.ajaxError()，然后使用“ajaxComplete”检查您的请求timedout, 或succeded.
