Instead there is picker view, but i need compact object like dropdown list box. Please suggest me how to add or create this. Thanks in advance. 回答1: No such thing exists. You can either create your own control, or use UIPicker. Creating your own drop-down control is quite a bunch of work, compared to using the Picker, and unless that particular control is mission-critical, I'd recommend you figure out how to use UIPicker inside your existing design

I understand what the error means: an exception is getting thrown someplace it can't be thrown. I've even managed to track it down somewhat―it's happening during the time shutdown functions are being called. I've put logging in all the functions which get registered with register_shutdown_function , and it's not happening in any of those. Unfortunately, I

The second is a click event where a slideup/down command is executed when a link is clicked. Both these scripts work separately but I cannot get them to work together. Here is the timed slideup/down script: $(document).ready(function() { $('.slide-out-div').hide(); $('.slide-out-div') .delay(5000) .slideDown(300); $('.slide-out-div') .delay(5000) .slideUp(500); }); Here is the click script: window.onload = function() { $

If not does anyone with some experience with slickgrid know how I should go about adding this option? Thanks 回答1: I assume you mean a custom cell editor. Here's a sample select-based boolean cell editor from slick.editors.js. You could easily modify it to work with an arbitrary set of possible values. function YesNoSelectCellEditor($container, columnDef, value, dataContext) { var $select; var defaultValue = value; var scope =

With the help of tutorials provided by Apache POI , I am able to create a Drop-down list in an Excel sheet, but I also need to read the drop-down list content when reading that again, so that I can render a similar drop-down list on a UI. Any suggestions? 回答1: I can't seem to find any mechanism in HSSF to retrieve the DataValidation s from the HSSFSheet . So if you have a .xls file, you're out of luck. However, if you have

When a turtle lands on one of the yellow patches, I'd like it to stop on that patch and stay there for 15 ticks whilst it 'investigates' the bait. After 15 ticks have elapsed I want the turtles to continue moving as usual until they encounter another yellow patch. I've attempted to modify parts of this parked card model in the netlogo modelling commons but couldn't
