How do I select an element in jQuery by using a variable for the ID?

Question

For example, the following selects a division with id=\"2\":

row = $(\"body\").find(\"#2\");

How do I do something like this:

r         


        

Answer 1

I don't know much about jQuery, but try this:

row_id = "#5";
row = $("body").find(row_id);

Edit: Of course, if the variable is a number, you have to add "#" to the front:

row_id = 5
row = $("body").find("#"+row_id);
