Using variables in a jQuery function

Question

This line $(''+fullId+'') is giving me problems. I've created an array in a different function that gets the #id's of all the inputs in the DOM.

Now with this function i'm trying to create a blur and focus jQuery function. I've set the variable fullId to prepend the '"#' and append the '"' to the variable name, but how do I get it to work?

$(''+fullId+'') is not doing the trick and neither does $(fullId)

function focusBlur () {
 var inputId = 0;
 var fullId = 0;
 for(var i=0; i<size; i++) {
 inputId = arr.shift();
 fullId = "\"#"+inputId+"\"";
 $(''+fullId+'').blur(function() {
 });
 $(''+fullId+'').focus(function() {
 });
 }
 }

Answer 1

Try $("#" + inputId)

Answer 2

You don't need the double quotes. Just use:

fullId = "#" + inputId;

instead of:

fullId = "\"#"+inputId+"\"";

Answer 3

$(fullId).blur(function() {});

Ah, yeah, I missed adding the double-quotes. They're not necessary when the id is stored in a variable.

Answer 4

could you try

var fullId = "#"+inputId;
$(fullId).blur(function() {
 });
$(fullId).focus(function() {
 });
