Using $.ajaxSetup is global for all ajax calls. Because the $.get function doesn't have any error callbacks, defining an error handler in $.ajaxSetup is the only way to handle errors. If you use $.ajax, you can define the error handler in the $.ajax call like this
$.ajax({
url: "HTMLPage.htm",
success: function(data) {
alert(data);
$('#mydiv').html(data);
},
error: function(XMLHttpRequest, textStatus, errorThrown) {
if (XMLHttpRequest.status == 0) {
alert(' Check Your Network.');
} else if (XMLHttpRequest.status == 404) {
alert('Requested URL not found.');
} else if (XMLHttpRequest.status == 500) {
alert('Internel Server Error.');
} else {
alert('Unknow Error.\n' + XMLHttpRequest.responseText);
}
}
});
This is specific to only this ajax call, that way you can have more specific error messages. But using the global error handler works just as well.
You could define your functions outside of the $(document).ready() like this
$(document).ready(function() {
$.ajaxSetup({
error: AjaxError
});
$.get("HTMLPage.htm", GetSuccess);
});
function AjaxError(x, e) {
if (x.status == 0) {
alert(' Check Your Network.');
} else if (x.status == 404) {
alert('Requested URL not found.');
} else if (x.status == 500) {
alert('Internel Server Error.');
} else {
alert('Unknow Error.\n' + x.responseText);
}
}
function GetSuccess(data) {
alert(data);
$('#mydiv').html(data);
}
