form-submit

问题 I need to submit some information to my servlet. Once I submit this information, I'll receive a PDF from the servlet based on the data. I know I can construct the URL and pass parameters to it using HTTP GET. Suppose my form data is too large.So is it possible to do this using a hidden iFrame? I'll submit the parameters using the hidden iFrame and in my servlet, I write the PDF to the response stream. Will this work? If it works can someone please suggest me how to do this? 回答1: You'll need

问题 I want to make a button that starts my php script after I click it. So do I just make 2 separate files and have action post to the php file and then let it start? or is there a better way to do this? Possibly in one document? Update: Well, I basically made a script that would do a series of a loops until it's finished.

问题 I use jquery's .submit() to intercept user's submit event, however I found a problem. When the user single click the submit button, the form is submitted normally, but if a user deliberately fast click it multiple times, it will submit multiple times, which will cause duplicated data in the database.

问题 This question already has answers here : Submit form without page reloading (17 answers) Closed 6 years ago . I have a function built in JavaScript that I want to be executed after a form submit is hit. It basically changes the look of the page completely. But I need a variable from the search box to still go through to the JavaScript. At the moment it flashes and resets what was there because it reloads the page. So I set up a return false in my function which keeps it from doing that but

问题 I have the following code: <script type="text/javascript"> function SubmitForm() { form1.submit(); } function ShowResponse() { } </script> . . . <div> <a href="#" onclick="SubmitForm();">Click</a> </div> I want to capture the html response of form1.submit ?

问题 I need to call some functions in sequence on form submit button click - func1() -> func2() -> func3() ... -> func7() -> ... All these functions do some kind of validation/checking and if validation fails, display a confirmation dialog to the user. If the user confirms, the next function in queue is executed. Any of these functions could be doing some asynchronous task like sending Ajax request and depending on the result, showing the user some confirm dialog. Details I have asynchronous

问题 So i have a simple question, but i cant find the answer to it. I have a form in which a user types something into the textfield and clicks the submit button with the value "Add".
