问题 I'm trying to change the acceptedFiles Option of a previously created Dropzone. This is how I set the Options: $myDropzone.options.acceptedFiles = '.jpg, .png'; and this is the generated Dropzone: var $myDropzone = $("#my-dropzone"); $myDropzone.dropzone({ maxFiles: 100, maxFilesize: 32, acceptedFiles: ".jpg"}); The resulting error is: TypeError: $myDropzone.options is undefined UPDATE: Seems like this is not running any errors: $myDropzone.options = { acceptedFiles: '.jpg, .png' }; But there

问题 I have multiple buttons having "item-submit" as class name. I wanted to dynamically append contents as shown in the code below when the button is clicked. The thing is, the click event is only being called on the first button. Clicking another button will not add any content, and worse, will reload the entire page. As you can see in the code, the variable table is being appended to order-table, which were created dynamically. This is also where the item-submit button resides where I wanted to

问题 Sorry that I had to re-edit this question. I need to dynamically parse two string values to the appropriate type and compare them, then return a bool result. Example 1: string lhs = “10”; string rhs = “10”; Compare.DoesEqual(lhs, rhs, typeof(int)); //true Compare.DoesEqual(lhs, rhs, typeof(string)); //true Example 2: string lhs = “2.0”; string rhs = “3.1”; Compare.IsGreaterThan(lhs, rhs, typeof(int)); //false Compare.IsGreaterThan(lhs, rhs, typeof(double)); //false Compare.IsGreaterThan(lhs,

问题 I am programming with the C++ Builder from Embarcadero.I created an TImage Array : TImage *Image[c] ; // c is 5 after that I am creating dynamic Images on an BUTTON CLICK : for (int i = 0; i < c; i++) { Image[i] = new TImage(this); Image[i]->Parent = BoardItem ; // BoardItem is an Item of an TabControl Image[i]->Height = 20 ; Image[i]->Width = 20 ; Image[i]->Position->X = d ; // d and e are defined in the public var's. Image[i]->Position->Y = e ; Image[i]->Bitmap = Icon->Bitmap ; // Icon is

问题 int i = amount; //amount will always start at 0 int j = i + 1; GroupBox[] verGroup; verGroup = new GroupBox[i]; verGroup[i].Name = "verGroup" + i.ToString(); verGroup[i].Width = 400; verGroup[i].Height = 120; verGroup[i].Left = 5; verGroup[i].Top = 5 + (verGroup[i].Height * i) + (10 * i); verGroup[i].Text = "Verification #" + j.ToString(); pnlVer.Controls.Add(verGroup[i]); It gives me an IndexOutofRangeException at verGroup[i].Name. But index is 0, which is surely what it wants? I've also

问题 I have a script containing $('a').on('click', function () {alert($(this).attr('class')); }); In my contextmenu function, I create a list with links $(function () { $('a').on('contextmenu', function (event) { $("<ul id='menu'></ul>") .append('<li><a href="#" class="test">Test 1</a></li>') .append('<li><a href="">Test 2</a></li>') .appendTo("body") .css({ top: event.pageY + "px", left: event.pageX + "px" }); return false; }); }); However, the first piece of code (the on click event) does not

问题 From the dynamic form I added. I realized that I can't get a gif animation to run in the form's background. So I thought I'd give it a try by embeding a picturebox on the dynamic form, but it's not working hence why I'm here. So on my main form (Form1) I have 2 buttons, openfiledialog, and a picturebox. When you click button1 you browse for the an image to display in the picturebox, and when you press button2 as you can see from the code below. It'll open a new form, but what I want is to
