问题 I have this code in a js file: function buildRolePicker() { var pnl = $("[id$='staffRoles']"); $.each(roles["ContactGroupRoles"], function(iteration, item) { pnl.append( $(document.createElement("input")).attr({ id: 'cgr' + item['RoleId'], name: 'cgroles', value: item['RoleId'], title: item['RoleName'], type: 'checkbox' }) ); pnl.append( $(document.createElement('label')).attr({ 'for': 'cgr' + item['RoleId'] }) .text(item['RoleName']) ); }); alert(document.forms[0].cgroles[8].value); } I was

问题 I need a functionality in storm that i know (based on the docs) has not been yet implemented. I need to add more tasks at runtime without the need to have an initial large number of tasks, because it might cause performance issues. because Running more than one task per executor does not increase the level of parallelism -- an executor always has one thread that it uses for all of its tasks, which means that tasks run serially on an executor. I know that rebalance command can be used to add

问题 Is there any way ( without using Express Checkout ) to change the default text of "Item total" on the Order Summary PayPal payment page? Referring only to the image on my previous question: Adding item total to PayPal's order summary, for full aggregate cart payment I'm referring only to the image because I'm simply not using cart upload now. I am instead using the ButtonManagerAPI to dynamically create buttons with the right total cart price. All I'm trying to do now is change the text of

问题 I am using bx Slider, using external controls for previous and next slide. All is working fine. However, I am using floating elements for the controls, since I want them in a line and filling the whole containing div (as in this question CSS three inline elements with align from left to right, how to occupy all available width ) However, the controls are generated dynamically by bxSlider, and for some strange reason, if the elements are floating hover is not recognized Here is an example page

问题 I want to generate a certain number of divs using PHP with different ids, I know how to generate them for a set number, but how do I generate on click, with different ids? Also, if I wanted to delete a div (and its corresponding id) how would I do that? This is the code I have for generating (6) divs $element = "<div></div>"; $count = 6; foreach( range(1,$count) as $item){ echo $element; } I need something like the click() in jquery/javscript (but in PHP) to trigger div creation instead and I

问题 In an ASP.NET project, I generate N number of editboxes depending on a database query result at the launch of my app. Each textbox has an id="textNid" with N = 0, 1 , 2... I understood that I could not play with editboxfor in this case, so I generate some input texts at the success of an AJAX call at the launch of my app. Something like: for (var i = 0; i < data.length; i++) { htmlToWrite += "<input type=\"text\" "value=\"" + data[i] + "\"" + "id=\"text" + i + "id\"\"> ... It displays fine, I

问题 I have developed a Qt GUI using Qt4 and PyQt. I am trying to implement a graph that will dynamically "live update" the graph to represent the rate at which the data is being transmitted in a (data/sec format). However, the problem lies within implementing a graph that can cleanly live update, not finding the speed. Any suggestions would be greatly appreciated. For the record, I want this to be built in as a widget within the GUI not a separate pop-up window. Regards, sudo!! 回答1: I suggest you

问题 I want to make a dynamic string generator that will generate all possible unique strings from a character set with a dynamic length. I can make this very easily using for loops but then its static and not dynamic length. // Prints all possible strings with the length of 3 for a in allowedCharacters { for b in allowedCharacters { for c in allowedCharacters { println(a+b+c) } } } But when I want to make this dynamic of length so I can just call generate(length: 5) I get confused. I found this

问题 I am dynamically adding HTML from another page and styling it for print. However, page-break-inside: avoid; , when applied to my elements (any of them), does not seem to be taken into account when printing even though it shows up in the styles. I am using Chrome 31 on Windows Here is a jsFiddle of the simplified version of my program ( WARNING : It brings up the print preview after 3 seconds. To stop this simply comment out the setInterval at the bottom), This is the version where page-break
