clone

问题 In this question Cloning a bootstrap element with an event listener I asked how to clone an element without copying the bootstrap-supplied event listener. And the answer is to not pass true to the clone() command. As it turns out, I see now that my problem is a bit more complicated than that. What I actually have is a div containing several buttons, one of which controls the expand/collapse of an associated div, and others of which provide other specialized functionality, which are provided

问题 Trying to clone base element li.table-field-base to variable clonedItem , change some attributes and data on the new element and then append it to sortable list ul#tablefield-order-sortable . The result is that the element is appended, but the base element is removed, though i did copy it first. How could i keep the base element, so i can use it later again? Following is the piece of relevant code that does the copying/appending part: var clonedItem = $.extend({}, $('li.table-field-base')); $

问题 I am using the Typed.React library which includes a method to extend one prototype definition with that of another: function extractPrototype(clazz) { var proto = {}; for (var key in clazz.prototype) { proto[key] = clazz.prototype[key]; } return proto; } If the provided class defines property methods, this function has a side effect of executing the get method e.g. var TestObject = (function () { function TestObject() { this.str = "test string"; } Object.defineProperty(TestObject.prototype,

问题 I have the following code (simplified to see the logic behind): <div id="alfa">Text <script> $("#alfa").click(function() { alert($(this).attr("id")); }); </script> </div> <script> var clone = $("#alfa").clone().attr("id",$("#alfa").attr("id")+"_1"); $("#alfa").after(clone); </script> I need to see "alfa_1" when I click in the cloned Text, but nothing happens. When I use clone(true,true) that works, but I don't see the code of the cloned div in Firebug to see what really happens. Also I don't

问题 I'm using plain vanilla JavaScript to clone fieldsets and change the ID/name attributes of any of the form fields within the fieldset. Everything works properly, except in IE7 the cloned radio buttons are all treated as one group. For example, in one fieldset, I have two radio buttons. When I clone it and add another fieldset, then click in the last radio button of the new fieldset, it unchecks the very first radio button. This appears to be a bug in IE7 where it doesn't change the name

问题 I have a "sheet1" containing several headings and i'm looking to see if there is a formula i can ran that will scan, filter only the rows whereas the Column G has the status as "open". see example: http://s18.postimage.org/897u71lnt/excel2.png I want all of the "Open" items to be copied on the "sheet2" automatically.

问题 I'm looking at this fiddle http://jsfiddle.net/yezw6c51/1/ which does what I need to do with one exception. When you load it has one Input field named 'phone_number' When you click on Add phone number you can add multiple rows/input fields as such : Each new input field that is added has had it's field name incremented. eg : phone_number1, phone_number2 etc. This works fine. But I'd like the text before each input field to also have the incremented value adding as well, so you end up with :

问题 void *stack; stack = malloc(STACK_SIZE); if (-1 == clone(child_thread, stack + STACK_SIZE, 0, NULL)) { perror("clone failed:"); } while(waitid(P_ALL, 0, NULL, WEXITED) != 0){ perror("waitid failed:"); sleep(1); } The manual says: If a child has already changed state, then these calls return immediately. Otherwise they block until either a child changes state But in fact it returns immediately : waitid failed:: No child processes waitid failed:: No child processes ... Any advice? 回答1: You are
