问题 Is there an easy way to have an HTML form on a webpage that, when the user submits, puts the data into a PDF file and sends it to the receiver? The webpage is running on .net. Thanks 回答1: Umbraco has a good PDF generator package called "XSL to PDF". It wil allow you to generate a PDF file from Umbraco just by defining a PDF template. Using this you should be able to achieve what you are looking for. 回答2: If you have C# use one of this libraries : http://csharp-source.net/open-source/pdf

问题 While plucking from a database, I get id as strings. $alphabets = new Alphabet(); return $alphabets->pluck('name', 'id'); Output { "1": "Apple", "2": "Ball", "3": "Cat" } Expected { 1: "Apple", 2: "Ball", 3: "Cat" } But, when I reverse ID and name , return $alphabets->pluck('id', 'name'); I get id as integer. { "Apple": 1, "Ball": 2, "Cat": 3 } I'm not sure what's happening behind the scene. But how can I get ID in integer ? Actually, old flash session doesn't set value because of 1 vs "1" in

But this me guessing as when I click on the icon property you have to browse to some icon. 回答1: Set ShowIcon Property of the form to False to see if that's what your client wants. 回答2: There are two ways. First is to create an empty Icon file and then Select Form -> Right Click -> Goto Properties -> Goto Icon -> Select your file. The other approach is to set FormBorderStyle of the form

问题 I'm new to using JSfiddle and get this error: {"error": "Please use POST request"} everytime I submit the form. What I have understood, you cannot submit a post request in JSfiddle, so how I can append something to a form? <form> <label>Add</label> <input type="text"/> </form> $('form').on("submit", function(){ $('form').after("apple") }); 回答1: If you do not explicitly set a form method browsers will default to using GET. <form method="POST"> 来源： https://stackoverflow.com/questions/24420736

问题 I've been binding submit events to forms, and ensuring that they do not break the form, using jQuery like this: jQuery('form').submit(function(e){ var form = this; e.preventDefault(); alert('1'); setTimeout(function() { alert('2'); form.submit(); }, 1000); }); This is all good and well, except, if for some reason a front end developer gave a child input of this form an id of ="submit", this breaks, as form.submit() throws a JavaScript error (In Chrome, 'Uncaught TypeError: Property 'submit'

问题 I am trying to build a filter for my portfolio website. Checkboxes that let you pick a technology (react, redux, jquery etc.) to display a piece of work(s) that contain(s) that/those technologies. So every time the user clicks on a box, I want to add the value (JavaScript, Redux, React etc.) to an array that I use in another function to check against my portfolio pieces and filter out what isn't there. I am finding this very difficult and I think it should be quite simple. Can someone point

问题 I have a classic ASP page that submits back to itself. Strangely, the values being returned from the selects have commas being added to the ends of them. Has anyone run into anything like this before? Any troubleshooting steps or tools recommended? I'm expecting the values to be returned just as numbers - they are the IDs of the values displayed in the option. I've checked for mystery commas in the page and can't locate any - nor in the data that I'm pulling through. (note - these are single

问题 I have Angular form that is built with help of FormBuilder. Form contains a FormArray which has as many fields as user wants. I've set validator for fields this.fb.array([this.fb.control('', Validators.required)]) and for each new push validator is the same. The problem is that I don't know how to access a specific field's isValid property since they are bound with FormControl via [formControlName]="index" . I've tried to do it that way, but it doesn't seem to work <div *ngIf="array.at(index)
