I need to see your submit button html tag for better help. I am not familiar with php and how it handles the postback, but I guess depending on what you want to do, you have three options: Getting the handling onclick button on the client-side: In this case you only need to call a … Read more
By using return false; in the JavaScript code that you call from the submit button, you can stop the form from submitting. Basically, you need the following HTML: <form onsubmit=”myFunction(); return false;”> <input type=”submit” value=”Submit”> </form> Then the supporting JavaScript code: <script language=”javascript”><!– function myFunction() { // Do stuff } //–></script> If you desire, you … Read more
I do this on the server-side. That is, the form always submits to the same target, but I’ve got a server-side script who is responsible for redirecting to the appropriate location depending on what button was pressed. If you have multiple buttons, such as <form action=”mypage” method=”get”> <input type=”submit” name=”retry” value=”Retry” /> <input type=”submit” name=”abort” … Read more
As @AliK mentioned, this can be done easily by looking at the value of the submit buttons. When you submit a form, unset variables will evaluate false. If you set both submit buttons to be part of the same form, you can just check and see which button has been set. HTML: <form action=”handle_user.php” method=”POST” … Read more
There were two things wrong with your code. The first one is that you included the $(document).ready(); but didn’t wrap the jQuery object that’s creating the element with it. The second was the method you were using. jQuery will create any element when the selector (or where you would usually put the selector) is replaced … Read more
On submitting, you would get an array as if created like this: $_POST[‘topdiameter’] = array( ‘first value’, ‘second value’ ); $_POST[‘bottomdiameter’] = array( ‘first value’, ‘second value’ ); However, I would suggest changing your form names to this format instead: name=”diameters[0][top]” name=”diameters[0][bottom]” name=”diameters[1][top]” name=”diameters[1][bottom]” … Using that format, it’s much easier to loop through the … Read more
Use unobtrusive javascript to disable the submit event on the form after it has already been submitted. Here is an example using jQuery. EDIT: Fixed issue with submitting a form without clicking the submit button. Thanks, ichiban. $(“body”).on(“submit”, “form”, function() { $(this).submit(function() { return false; }); return true; });
You need to give the button a name and a value. No control can be submitted without a name, and the content of a button element is the label, not the value. <form action=”” method=”post”> <button name=”foo” value=”upvote”>Upvote</button> </form>
Wrap all your fields in fieldset and use ngDisabled directive like this: <fieldset ng-disabled=”isSaving”> … inputs …</fieldset> It will automatically disable all inputs inside the fieldset. Then in controller set $scope.isSaving to true before http call and to false after.
I see two options to solve it: 1) Specify type=”button” explicitly (i think it’s more preferable): <button type=”button” (click)=”preview();”>Preview</button> According to W3 specification: http://w3c.github.io/html-reference/button.html A button element with no type attribute specified represents the same thing as a button element with its type attribute set to “submit”. 2) Use $event.preventDefault(): <button (click)=”preview(); $event.preventDefault()”>Preview</button> or <button … Read more
