I have a website where I rely on a lot of custom API call. My API return always an XML.
Currently, at the start of each and every $.get or $.post I call, I have this snippet :
var root = $($.parseXML(data)).find("Response");
if (root.children("Type").text() == "Error") {
toastr.error(root.children("Content").text(), "Error " + root.children("ReturnCode").text());
return;
}
However, I feel this code to be much redundant on one of my page, it's used 15 times.
I tried to use the $(document).ajaxSuccess() but the event.stopPropagation don't seem to work here
Is there a way to "intercept" each and every ajax call responses, do some stuff and possibly prevent the call to other defined success functions ?
I assume that you have something like this in many places in your code
$.ajax({
method: "GET",
url: "someurl.html",
dataType: "xml",
success : function() {
var root = $($.parseXML(data)).find("Response");
if (root.children("Type").text() == "Error") {
toastr.error(root.children("Content").text(), "Error " + root.children("ReturnCode").text());
return;
}
// ...
},
error : function(qXHR, textStatus, errorThrown){
toastr.error(errorThrown, "Error " + qXHR.status);
}
});
you could create a generic custom ajax function tha you can re-use
function baseAjaxCall(option, sCb) {
var ajaxOptions = {
method: option.method || "GET",
url: option.url,
dataType: option.dataType || "xml",
success : function(data) {
var root = $($.parseXML(data)).find("Response");
if (root.children("Type").text() == "Error") {
toastr.error(root.children("Content").text(), "Error " + root.children("ReturnCode").text());
return;
}
else {
sCb(root);
}
},
error : function(qXHR, textStatus, errorThrown){
toastr.error(errorThrown, "Error " + qXHR.status);
}
};
//you can check for optional settings
if(option.contentType !== undefined){
ajaxOptions.contentType = option.contentType;
}
$.ajax(ajaxOptions);
}
everywhere in your code you can re-use the baseAjaxCall function
baseAjaxCall({ url: "someurl.html" }, function(root){
// no need to chek for errors here!
});
Hope it's helps!
