I put together this LoadVars class for javascript for users who would rather deal with the flash LoadVars object than the XMLHttpRequest object (this LoadVars class is pretty much just a wrapper for that object). It’s quick and dirty but it works.
A few notes about the class:
¥ all requests use GET. the send and sendAndLoad methods will automatically convert the properties of the LV object to a query string and append it to the URL.
¥ You dont need to escape the return value coming back to the LV object. You can send a plain string if you like. However, you can set the LoadVars.parseVarString to true, and you can pass in a string like “myVar=This is the ver&myvar2=This is the secondvar.” You don’t need to encode the string, but if you do it will decode it.
¥ the return value is always accepted by the same LV object. In flash, you can specify a target object..that is not used here.
¥ only string or number datatypes may be used.
¥ getBytesLoaded/getBytesTotal aren’t implemented.
¥ there is a LoadVars.onLoadError method you can use to handle situations such as document not found.
You can test it out here.
