forms

问题 In a Delphi 10.4 VCL Application, I need to detect when the FORM RESIZING ENDS . (E.g. after the user resized the Form by dragging its size-grip). So I have placed a TApplicationEvents component on the form and created its OnMessage event-handler, trying to catch the WM_EXITSIZEMOVE message: procedure TformMain.ApplicationEvents1Message(var Msg: tagMSG; var Handled: Boolean); begin if (Msg.Message = WM_EXITSIZEMOVE) then begin CodeSite.Send('TformMain.ApplicationEvents1Message: WM

问题 New to PHP, but making new progress. I have a contact form that will send an email after it has been submitted by the user. Now I want to make this form better, by stripping out bad characters, or anything that could potentially wreck an email. The email will be read by me, so I could technically browse through all the spam, but I don't want to. I want a clean email coming in for documentation purposes. I am using the $_POST array, here is the HTML for the contact form: <form class="form"

问题 Can anyone please show me a specific example of a Symfony2 form entity update? The book only shows how to create a new entity. I need an example of how to update an existing entity where I initially pass the id of the entity on the query string. I'm having trouble understanding how to access the form again in the code that checks for a post without re-creating the form. And if I do recreate the form, it means I have to also query for the entity again, which doesn't seem to make much sense.

问题 I'm trying to point a button in my form tag to a different action/action class than the form but it won't work. I read in another thread that this is due to a bug in Struts 2 and that struts.mapper.action.prefix.enabled"="true" should be set, so I did it but it's still the same. I can use a different action pointing to a different method of the same action class that the form is using but when I try specifying a different action class it doesn't work. This works, (jsp) <s:form action="print">

问题 I have a form with bootstrap and Google Apps Script. I have defined a general validation for the form, but now I need to configure a specific validation for a field. If the input field with the id "estado" has the value "Terminado", the form should not be submitted. The value of the input field is generated by a google app script function and its updated when the input field "inputid" change. The input fields estado is determined by the value on "inputid". When i change the value of inputid

问题 I have a form that is being generated by legacy back-end code that, for a variety of reasons, I can't change. The form is straightforward HTML: <form action="#" id="theForm" onsubmit="return check_theForm(); method="post"> <!-- fields go here --> </form> On submission the onsubmit parameter fires to verify that all compulsory field have been filled in, using the check_theform() function which contains "plain vanilla" javascript (i.e. no jQuery code). In other words, basic stuff. I'm now
