Question

I’m trying to make jQuery Autocomplete, Yahoo Finance and Zend Framework work together.

What I want is to create a form field in which I can autocomplete tickers symbols through Yahoo API.

I’ve already created a Zend_From element that contains this :

    $this->setJQueryParam('source', new Zend_Json_Expr('function( request, response ) {
            $.ajax({
                type: "GET",
                dataType: "jsonp",
                jsonp: "callback",
                jsonpCallback: "YAHOO.Finance.SymbolSuggest.ssCallback",
                data: {
                    query: request.term
                },
                cache: true,
                url: "http://autoc.finance.yahoo.com/autoc";
                }
            });
        }'));
    $this->getView()->jQuery()->addJavascript('var YAHOO={Finance:{SymbolSuggest:{}}};');
    $this->getView()->jQuery()->addOnLoad('YAHOO.Finance.SymbolSuggest.ssCallback = function (data) {
                                            console.log(JSON.stringify(data)); }');

I found this post that resolved a part of my problem, but I think using var YAHOO={Finance:{SymbolSuggest:{}}}; is a dirty trick and isn’t the right way to do.

Now, if I type GOO in my field, then the firebug console will show me something like this:

{“ResultSet”:{“Query”:”goo”,”Result”:[{“symbol”:”GOOG”,”name”:”Google Inc.”,”exch”:”NMS”,”type”:”S”,”exchDisp”:”NASDAQ”,”typeDisp”:”Equity”},{“symbol”:”GT”,”name”:”Goodyear Tire & Rubber Co.”,”exch”:”NYQ”,”type”:”S”,”exchDisp”:”NYSE”,”typeDisp”:”Equity”}…

which is great, but I don’t know how to send back these data to Autocomplete from this callback function, any idea?

Answer 1

I have finally found a solution, but I’m still using YAHOO namespace though.

I first removed the last line (addOnLoad) and move its content right after the Ajax request so that I’m still into the autocomplete function and I can return the result to autocomplete.

Here is the final code:

$this->setJQueryParam('source', new Zend_Json_Expr('function( request, response ) {
        $.ajax({
            type: "GET",
            dataType: "jsonp",
            jsonp: "callback",
            jsonpCallback: "YAHOO.Finance.SymbolSuggest.ssCallback",
            data: {
                query: request.term
            },
            cache: true,
            url: "http://autoc.finance.yahoo.com/autoc";
            }
        });
        YAHOO.Finance.SymbolSuggest.ssCallback = function (data) {
            console.log(data.ResultSet.Result);
            response( $.map( data.ResultSet.Result, function( item ) { 
                return {
                    label: item.symbol,
                    value: item.name
                }
            }))
         }
    }'));
$this->getView()->jQuery()->addJavascript('var YAHOO={Finance:{SymbolSuggest:{}}};');

Hope it can help!
