jQuery's val() method change doesn't seem to change the DOM

Question

Doing $(\"#someId\").val(\"newValue\") doesn\'t change the DOM -- I can retrieve this value with $(\"#someId\").val(), but the element in the DOM s

Answer 1

This

$("#someId").val("newValue")

will change the value of the input element.

This

$("#someId").attr("value","newValue")

will change the value of the value attribute.

The second may help if you want to write the element. So, for example:

$("#someId").val("newValue")
$("#someId").attr("value","newValue")
write($("#someId").parent())

-will result in the new value being rendered, whereas

$("#someId").val("newValue")
write($("#someId").parent())

-will just show the original value.
