Is there an “after submit” jQuery option?

阅读更多关于 Is there an “after submit” jQuery option?

问题 I have a form that uploads a file and targets an iframe on the page. When the user clicks submit, I want the file contents to "clear" out. I tried this $('#imageaddform').submit(function(){ $('#imagefile').val(''); }); But it clears the form before the submit, so nothing is ever uploaded. Is how do I clear after submit? 回答1: If you have no other handlers bound, you could do something like this: $('#imageaddform').submit(function(e) { e.preventDefault(); // don't submit multiple times this

jQuery - add additional parameters on submit (NOT ajax)

阅读更多关于 jQuery - add additional parameters on submit (NOT ajax)

Using jQuery's 'submit' - is there a way to pass additional parameters to a form? I am NOT looking to do this with Ajax - this is normal, refresh-typical form submission. $('#submit').click(function () { $('#event').submit(function () { data: { form['attendees'] = $('#attendance').sortable('toArray').toString(); }); }); Michel This one did it for me: var input = $("<input>") .attr("type", "hidden") .attr("name", "mydata").val("bla"); $('#form1').append(input); is based on the Daff's answer, but added the NAME attribute to let it show in the form collection and changed VALUE to VAL Also checked

How do I create multiple submit buttons for the same form in Rails?

阅读更多关于 How do I create multiple submit buttons for the same form in Rails?

I need to have multiple submit buttons. I have a form which creates an instance of Contact_Call. One button creates it as normal. The other button creates it but needs to have a different :attribute value from the default, and it also needs to set the attribute on a different, but related model used in the controller. How do I do that? I can't change the route, so is there a way to send a different variable that gets picked up by [:params]? And if I do then, what do I do in the controller, set up a case statement? You can create multiple submit buttons and provide a different value to each: <%

How to capture submit event using jQuery in an ASP.NET application?

阅读更多关于 How to capture submit event using jQuery in an ASP.NET application?

问题 I\'m trying to handle the submit event of a form element using jQuery. $(\"form\").bind(\"submit\", function() { alert(\"You are submitting!\"); }); This never fires when the form submits (as part of a postback, e.g. when I click on a button or linkbutton). Is there a way to make this work? I could attach to events of the individual elements that trigger the submission, but that\'s less than ideal - there are just too many possibilities (e.g. dropdownlists with autopostback=true, keyboard

I've got a jsf 1.2 form with two buttons and several input fields. The first button discards the entered values and repopulates the page with values from a db, the second button saves the entered values. The problem occurs when the user presses enter while the cursor is in one of the input fields, the form gets submitted and the action associated with the first button gets executed. The code looks like this: <h:commandButton action="#{bean.reset}" value="Reset" /> <h:commandButton action="#{bean.save}" value="Save" />  Is it possible to

How do I capture response of form.submit

阅读更多关于 How do I capture response of form.submit

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 ? How do I do this? Can I register any callback function to form1.submit method? You won't be able to do this easily with plain javascript. When you post a form, the form inputs are sent to the server and your page is refreshed - the data is handled on the server side. That is, the submit() function doesn't actually return anything, it just

问题 I\'m creating an extremely basic script to assist me in one of my google spreadsheets. I\'ve successfully got a sidebar showing, with a few buttons (which function).

Let's say you create a wizard in an HTML form. One button goes back, and one goes forward. Since the back button appears first in the markup when you press Enter , it will use that button to submit the form. Example: <form>  <input type="text" name="field1" />  <input type="submit" name="prev" value="Previous Page" />  <input type="submit" name="next" value="Next Page" /> </form> I would like to get to decide which button is used to submit the

jQuery serializeArray doesn't include the submit button that was clicked

阅读更多关于 jQuery serializeArray doesn't include the submit button that was clicked

I have a form that has two buttons. One for saving a record and the other for cancelling the save procedure. I am using the rails.js (a common AJAX/jQuery plug-in for those of you not in the know) javascript file that works with jQuery for unobtrusive javascript/ajax calls. When I send the form data over ajax, I want the name and value of the button I clicked to be submitted with the rest of the data so that I can make a decision on what to do based on which button was clicked. The method in the rails.js file uses .serializeArray() for sending form data to the server. The problem is that this
