Retrieving components from Ajax response data

While I have a good grasp of PHP, diving into AJAX and dealing with JSON is proving to be quite challenging for me.

My PHP script simply delivers a straightforward JSON string like this:

{"bindings": [ {"ircEvent": "PRIVMSG", "method": "newURI", "regex": "^http://.*"},
{"ircEvent": "PRIVMSG", "method": "deleteURI", "regex": "^delete.*"}, 
{"ircEvent": "PRIVMSG", "method": "randomURI", "regex": "^random.*"} ] } I

I fetch it using the following code:

var fillDataMasterTable = $.ajax({          
    url: "/php/PrepareGoogleDataTable.php" +"?"+
                "SensorString="+SensorString + "&"+
                "TableType=" + TableType +"&"+
                "NoAbscissaBins=" + NoAbscissaBins + "&"+
                "DataTableName=" + DataTableName +"&"+
                "TimeUnit=" + TimeUnit +"&"+
                "TimeStart=" + TimeStart,          
    dataType:'json',          
    async: false          
}).responseText;    

$('#debug_div').html(fillDataMasterTable);

Retrieving the JSON string works fine, but my struggle begins when trying to access individual values. I attempted:

$('#debug_div').html(fillDataMasterTable.bindings);

However, this approach doesn't yield the desired results. Admittedly, I may be making a fundamental mistake here, and I am open to guidance in order to kickstart my understanding.

Answer №1

responseText is a characteristic of the XMLHttpRequest component, and it will not automatically convert to a JSON object after the initial request. Instead, it remains a String. Therefore, regardless of specifying "dataType" as "json", you must manually convert it to a JSON object:

 fillDataMasterTable = JSON.parse(fillDataMasterTable);

Once converted, you can access properties like this:

 fillDataMasterTable.bindings

Answer №2

Implement Jquery in the following manner:

$.each(fillDataMasterTable.bindings, function(i, obj) {
            $.each(obj, bindings(prop, val) {
                $('#debug_div').html(val);
            });
        });
