div load html 传参,jQuery load html specific div into webpage

having a bit of a issue

got four links when clicked i want to to load in content from an external html page into a div called content which slides down and shows the content from the external html page, but I want to use the href from the links to load in specific div tags from the external html page.. I'm nearly there just missing the final part.. I cant seem to use my variable inside my jquery load statement..

this is what ive got so far..

$("#services a").click(function(){

var href = $(this).attr("href");

console.log(href)

$('#content').slideToggle(function(){

$("#content").load("services.html" + href);

});

return false;

});

also if anyone could point me how to slide the content div back when selecting a different link and then show that content for that link.. would be great..

thanks guys..
