overflow

问题 I am using the datepicker control from jQuery-ui 1.8. from-date is a text input. I am attaching a very simple datepicker: $('#from-date').datepicker(); This causes the page to overflow (vertical scrollbar), which I am trying to avoid. As soon as I click the from-date, the datepicker control appears, and the scrollbar dissapears. After dismissing the datepicker, the scrollbar doesn't appear anymore. The text field is inside a div that has overflow:auto and a fixed height and width. I suspect

问题 I have an HTML page with a fixed-height div which should be scrollable (only vertically). In iOS 5 this can be achieved using: overflow-y: auto; -webkit-overflow-scrolling: touch; The div contains an unordered list with about 10 items. The scrolling works, but sometimes it scrolls only if I swipe my finger diagonally or even horizontally and not vertically as it should be. I'm wondering if anyone has encountered this issue. I don't want to think that it is a bug in iOS5, but I can't figure

问题 By default, when the contents of a textbox in SSRS overflows the width of the textbox, the textbox will grow vertically to accommodate its content. This feature can be turned off, by setting the "CanGrow" property of the textbox to "False". However, this abruptly cuts off the content, which is not ideal. I am looking for a way to clearly show the user that the text is too wide to fit the textbox. In the past, I've been using a simple expression to add an ellipsis "...", when the length of the

问题 Background: Given n balls such that: 'a' balls are of colour GREEN 'b' balls are of colour BLUE 'c' balls are of colour RED ... (of course a + b + c + ... = n ) The number of permutations in which these balls can be arranged is given by: perm = n! / (a! b! c! ..) Question 1: How can I 'elegantly' calculate perm so as to avoid an integer overflow as as long as possible , and be sure that when I am done calculating, I either have the correct value of perm , or I know that the final result will

问题 I would like to realize if condition in armv8 NEON inline assembly code. In armv7 this was possible through checking overflow bit like this: VMRS r4, FPSCR BIC r4, r4, #(1<<27) VMSR FPSCR, r4 vtst.16 d30, d30, d30 vqadd.u16 d30, d30, d30 vmrs r4, FPSCR tst r4, #(1<<27) bne label1 But I am not able to achieve this in armv8 equivalent code. It seems that SQADD doesnt affect overflow bit in FPSR or I cannot check it like this. Is it possible or is there better approach how to skip long part of

问题 I am using box-flex for my layout, but I am unable to get the flex box to scroll. HTML: <div class='dashboard'> <div><button>Widget</button></div> <div class="noboard"><button>Yammer</button> <div class="yammerboard" > <div><button>Dashboard22</button></div> <div><button>Dashboard22</button></div> <div><button>Dashboard22</button></div> <div><button>Dashboard22</button></div> <div><button>Dashboard22</button></div> </div> </div> <div><button>Notifications</button></div> </div> CSS: .dashboard

问题 Consider the following piece of C code: #include <stdint.h> uint32_t inc(uint16_t x) { return x+1; } When compiled with gcc-4.4.3 with flags -std=c99 -march=core2 -msse4.1 -O2 -pipe -Wall on a pure x86_64 system, it produces movzwl %di,%eax inc %eax retq Now, unsigned overflow is predicted in C. I do not know much about x86_64 assembly, but as far as I can see the 16bit argument register is being moved to a 32bit register, which is incremented and returned. My question is, what if x == UINT16

问题 This question already has answers here : Catch and compute overflow during multiplication of two large integers (12 answers) Closed 5 years ago . int isOverflow(uint a, uint b) { // a and b are unsigned non-zero integers. uint c = a * b; if (c < ( a > b ? a : b)) return 1; else return 0; } Am I missing something ? I think the above snippet will work. EDIT : I have seen other solutions like multiplication of large numbers, how to catch overflow which uses some fancy methods to check it. But to

问题 I am experiencing some behavior that I don't understand. When I set up a list of badges with a max-height on the list and margin on the list items then the content for the list items overflows their containers proportionally to the margin. .badgers { display: flex; flex-direction: column; max-height: 10em; overflow: auto; border: 1px dashed red; } .badge, .title, .location, .timestamp { display: flex; } .badge { flex-direction: column; border: 1px solid black; margin: 1em 0; } <div class=

问题 I have read this CSS overflow-x hidden and overflow-y visible (and a lot of other posts) but i can't get this to work in my specific case. I'm using ths slick-slider and want to add dropdown-navigation. so i have to use a special markup. The dropdown should overflow the slider. I recreated the problem in the fiddle Thank you for your help! 回答1: Setting overflow-x or overflow-y to hidden causes the other to be treated as if it has a value of auto. So slick-slider adds a scrollbar for any
