[web/ajax] don't override any status code with 500 in ajax_error_handler
If the request produced an error such as Unauthorized or NotFound,
core_handle sets an appropriate status_out. Which is then overridden by
the ajax error handler.
// This contains template-specific javascript
function filterLog(domid, thresholdLevel) {
var logLevels = ["Debug", "Info", "Warning", "Error", "Fatal"]
var action = "hide";
for (var idx = 0; idx < logLevels.length; idx++){
var level = logLevels[idx];
if (level === thresholdLevel){
action = "show";
}
$('#'+domid+' .log' + level)[action]();
}
}
