jQuery ajax responseText empty

I ran into a problem using the $.ajax command synchronously in jQuery. I'd make my call. But when I get the XMLHttpRequest object back, the responseText was empty. My call looked like this. 

var response = $.ajax({
	url:		'/formCheck',
	type:		'POST',
	cache:		false,
	asynch:		false,
	data:		postObj,
});

console.log(response.responseText);

After wasting 2 hours trying to figure out what was wrong, I noticed that I had a spelling error in my request object. The asynch should be async (no h). I fixed this typo and everything started working as it should.

So if you can't get the jQuery ajax command to work synchronously and return the responseText, check your calling object. The JSON format is very convenient, but if you make a mistake in the naming of a parameter it just gets ignored and you're left scratching your head.

I was facing response text character limit problem. I had a somewhat large amount of data in proposed responseText to get and everything was working well while testing. But it stopped to show the data at once and just loader would show spinning. I debugged a lot to find out a reason and finally got that it did not support more than 8442 characters in "html" response type. Here is the code i was trying to get the data:

var url = "load_pocket_fabrics.php?filter=" + $("#eleID").val();
$.ajax({
url: url,
type: 'GET',
dataType: 'html',
timeout: 1000,
async:false,
before: $("#contentID").prev("div.loader").show(),
success: function(msg){
alert(msg);return;
}
});


Searching for a solution i end up on this post and tried async=false in the code and it worked!

Thanks for this wonderful post!
