Ajax Success and Error function failure

Solution 1:

Try this:

$.ajax({
    beforeSend: function() { textreplace(description); },
    type: "POST",  
    url: "updatedjob.php",
    data: "jobID="+ job +"& description="+ description +"& startDate="+ startDate +"& releaseDate="+ releaseDate +"& status="+ status, 
    success: function(){  
        $("form#updatejob").hide(function(){$("div.success").fadeIn();});  
    },
    error: function(XMLHttpRequest, textStatus, errorThrown) { 
        alert("Status: " + textStatus); alert("Error: " + errorThrown); 
    }       
});

The beforeSend property is set to function() { textreplace(description); } instead of textreplace(description). The beforeSend property needs a function.

Solution 2:

One also may use the following to catch the errors:

$.ajax({
    url: url, 
    success: function (data) {
        // Handle success here
        $('#editor-content-container').html(data);
        $('#editor-container').modal('show');
    },
    cache: false
}).fail(function (jqXHR, textStatus, error) {
    // Handle error here
    $('#editor-content-container').html(jqXHR.responseText);
    $('#editor-container').modal('show');
});

Solution 3:

I was having the same issue and fixed it by simply adding a dataType = "text" line to my ajax call. Make the dataType match the response you expect to get back from the server (your "insert successful" or "something went wrong" error message).

Solution 4:

You can implement error-specific logic as follows:

error: function (XMLHttpRequest, textStatus, errorThrown) {
    if (textStatus == 'Unauthorized') {
        alert('custom message. Error: ' + errorThrown);
    } else {
        alert('custom message. Error: ' + errorThrown);
    }
}
