form-submit

问题 In ASP.NET webforms and ASP 3 (Classic ASP), I came across an issue whereby naming your form submit button \"submit\" would \"break things\". Below is the rendered HTML: <input type=\"submit\" name=\"Submit\" value=\"Submit\" id=\"Submit\" /> I say \"break things\" because I\'m not sure exactly why or what happened. But the symptoms usually were that pressing the submit button sometimes did nothing i.e. it just didn\'t work. But sometimes it did work. In fact, I just built a quick one page

问题 My website involves a user submitting data over several pages of forms. I can pass data submitted on one page straight to the next page, but how do I go about sending it to pages after that? Here\'s a very simplified version of what I\'m doing. Page 1: <?php echo \"<form action=\'page2.php\' method=\'post\'> Please enter your name: <input type=\'text\' name=\'Name\'/> <input type=\'submit\' value=\'Submit\'/></form>\"; ?> Page 2: <?php $name=$_POST[\"Name\"]; echo \"Hello $name!<br/> <form

问题 We pull data from server and for that If we are using Struts, then we can pull either by submitting a page which MVC Architecture or we cam make an AJAX call but conventions is of using forms and render response but we also face challenges to give rich user experience, so we compromise convention and start using excessive AJAX, so how we should make balance between two? 回答1: I personally think that AJAX should be used for displays updates and form submissions should be done via a page reload.

问题 I\'m working with a form for which the mark-up I can\'t change & can\'t use jQuery. Currently the form post the results to a new window. Is it possible to change this to an ajax form so that the results displays on submit instead without altering any mark-up? Pulling the results (mark-up) from the results page back to the form page. Here is the mark-up for the form. <form class=\"form-poll\" id=\"poll-1225962377536\" action=\"/cs/Satellite\" target=\"_blank\"> <div class=\"form-item\">

问题 When the page loads everything works fine. But when I submit the form my dropdownlists are loosing the previous selected items after page refresh. How can I modify my function to initialize the dropdownlists and keep the previous selected items (on both) if they exist. Here is my view with the javascript that initializes my dropdownlists: @model Models.Book @{ ViewBag.Title = \"Index\"; } @section scripts { <script type=\"text/javascript\"> $(function() { $.getJSON(\"/Home/Books/List\",

问题 I have the following code on my site (using php and smarty) to try and avoid a form resubmitting when I hit f5: if ($this->bln_added == false) { if (isset($_POST[\'submit\'])) { $this->obj_site->obj_smarty->assign(\'title\', $_POST[\'tas_heading\']); $this->obj_site->obj_smarty->assign(\'desc\', $_POST[\'tas_description\']); } } else { $this->obj_site->obj_smarty->assign(\'title\', \'\'); $this->obj_site->obj_smarty->assign(\'desc\', \'\'); unset($_POST); } bln_added is false by default, but

问题 I\'m working on an ASP.NET 4.0 Web Forms project, after a break of about 5 years, and I\'m confused about the submit behaviour. In the click event of a button, I sleep the thread so that I can click the submit button multiple times. From what I can tell, ASP.NET is preventing the click event being called more than once. Is this true? BTW: I\'ve turned off javascript for this test. 回答1: " ASP.NET is preventing the click event being called more than once. Is this true? " No , actually what is

问题 We\'re using JSF 2.0 on WebSphere v8.5 with several component libraries PrimeFaces 4.0, Tomahawk 2.0, RichFaces, etc. I am looking for generic mechanism to avoid form re-submission when the page is refreshed, or when the submit button is clicked once again. I have many applications with different scenarios. For now I have considered disabling the button with a piece of JavaScript in onclick attribute, but this is not satisfying. I\'m looking for a pure Java implementation for this purpose,

问题 Question: How can you send a form with Javascript if one form input has the name submit ? Background: I am redirecting the user to another page with a hidden HTML form. I cannot change name on the (hidden) inputs, since the other page is on another server and the inputs need to be exactly as they are.

问题 I\'m trying to send a form\'s data using jQuery. However, data does not reach the server. Can you please tell me what I\'m doing wrong?
