offset

问题 I just wrote this for scrolling pages which is working fine and does what it should.. $('#nav a').click(function(){ var sid = $(this).attr('id'); $('html,body').animate({ scrollTop: $('#'+ sid +'-content').offset().top - 200}, 1000); return false; }); ..but I want the offset to be calculated by % rather then px ie rather then top - 200 it could be top - 30% any ideas how to accomplish this? As always any help is appreciated and thanks in advance. Quick Edit: The current 3 answers (thank you)

问题 I'm trying to update a table in Oracle and I'm running into some difficulty. I'm porting over my code from MySQL and some of the commands that MySQL allows are not supported in Oracle.

问题 This question already has answers here : Closed 8 years ago . Possible Duplicates: Does the 'offsetof' macro from <stddef.h> invoke undefined behaviour? dereferencing the null pointer #define _OFFS_OF_MEMBER(p_type, p_member) (size_t)&(((p_type *)NULL)->p_member) struct a { int a, b; }; size_t l = _OFFS_OF_MEMBER(struct a, b); I had a little chat/conversation with some fellow users, and one of them said that this is dereferencing and accessing the address space near address NULL. I said:

问题 What does offsetLeftAndRight() exactly do? Documentation says: "Offset this view's horizontal location by the specified amount of pixels" So, does it mean that if the view's left position is suppose 50 and offsetLeftAndRight(20) is called on it, then the view will move by 20pixels & its left position will be (50-20) i.e. 30? Thanks in advance. 回答1: Both the left and the right positions will be incremented by the offset. So in your example, the left position will change to 50 + 20 = 70. 来源：

If i´m pressing the toggle button twice it looks like it should -.-' Any idea what i have
