jQuery val vs attr value

0 votes
I had thought these two were the same, but they appear to not be. I've generally been using $obj.attr("value") to work with form fields, but on the page I'm currently building, $obj.attr("value") does not return the text I enter in my field. However, $obj.val() does.

On a different page I've built, both $obj.attr("value") and $obj.val() return the text entered in the form field.

What could account for $obj.attr("value") working as expected in one case but not in another?

What is the proper way to set and retrieve a form field's value using jQuery?

There is a big difference between an objects properties and an objects attributes

See this questions (and its answers) for some of the differences: .prop() vs .attr()

The gist is that .attr(...) is only getting the objects value at the start (when the html is created). val() is getting the object's property value which can change many times.
