Jquery defining id with a variable

So this works fine, as you all know

$("#foo").html = "bar";

But how would I do this?

var i = 开发者_StackOverflow"foo";
$(i).html= "bar";

I've tried $("#"+i) as well, but that doesn't work either.

This does not work.

$("#foo").html = "bar"; //Overwrites the object's html function with a string

This should.

$("#"+i).html("bar"); //Sets the inner HTML of the selected element.

i don't know what are you tring to do

but if you want to insert this value bar in the id='foo'

you can use

   var i = "foo" ;

   $('#'+i).html("bar");
