jQuery YQL

Version 0.3.0

What is this ?

A simple jQuery plugin that queries Yahoo's YQL, fetch the results through JSONP, and calls success callback with the results.

In a nutshell:

<script type="text/javascript" src="jquery.yql.js"></script> <script type="text/javascript"> $(function(){ $.yql( "SELECT * FROM github.repo WHERE id=#{username} AND repo=@repository", { username: "gabrielfalcao", repository: "jquery-yql" }, function (data) { if (data.results.repository["open-issues"].content > 0) { alert("Hey dude, you should check out your new issues!"); } } ); }); </script>

Explanation

jquery-yql automatically handles variable replacement within the query.

So if you use a query that looks like this:

"SELECT * FROM some_yql_table WHERE some_field=#{foo} AND another_field=#{bar}"

with the object:

{
    'foo': 'Just a string',
    'bar': 42
}

You don't need to worry about adding quotes to non-numeric fields, for example. Because we already do it for you.

Thus, the query above will become this:

'SELECT * FROM some_yql_table WHERE some_field="Just a string" AND another_field=42'

See ? jquery-yql automatically identifies if the value must be a string or number.

"@" variables

Because of the ticket #4 I've added support to @variable too. So it's not a big deal, just works in the same way of the #{variable}.

But allow me show it:

"SELECT * FROM some_yql_table WHERE some_field=@foo AND another_field=@bar"

becomes:

'SELECT * FROM some_yql_table WHERE some_field="Just a string" AND another_field=42'

Last thing

If you left variables without the respective key-value mapping mapped in the translation object, jquery-yql will not touch it.

Once again, I show you:

"SELECT * FROM person WHERE name=@name AND age=#{years} AND wealth=@value'

with

{
    'name': 'Gabriel',
    'years': '22'
}

Then, jquery-yql will resolve to:

'SELECT * FROM person WHERE name="Gabriel" AND age=22 AND wealth=@value'
