问题 I have an HTML form which targets _blank . I would like the page that form is on to reload after submitting. So here's some sample markup: <form method="POST" action="result.php" target="_blank"> <label for="name">Name:</label> <input type="text" name="name" /> <label for="email">Email:</label> <input type="email" name="email" /> <input type="submit" value="submit" /> </form> So when you submit this form it will POST to result.php in a new window or tab. This leaves the form page as is. I

问题 My onsubmit is not working. My idea was to put some mandatory fields and, in order to achieve that, I was using the onsubmit method inside a form in HTML that called a JavaScript function. The idea was if all the mandatory fields were filled, the javascript function would return true and it would move on to page /control/Cadastro.php . Otherwise, if any mandatory field was empty, it would return false and it wouldn't move to page /control/Cadastro.php , staying in the current page until true.

Does anyone know how to onsubmit multiple functions? What I intented to do was: onsubmit checks if all these functions return true, if all of them return true, then I do the action="checked.html" <form id="myForm" name="myForm" action="checked.html" method="post" onsubmit="return validateName() || validatePhone() || validateAddress() || validateEmail()"> However, what actually happened was, the computer checks the code from left to right, and the result of the next function will replace the previous one, and so on, until the end. So, even if all the 3 first functions return false, as long as

onSubmit returning false is not working

阅读更多关于 onSubmit returning false is not working

问题 I'm completely confused ... I'd swear this was working yesterday ... I woke up this morning and all my forms stopped to work in my project. All the forms have a "onsubmit" to a function that returns false since it's an ajax call, so the form is never sent. After a lot of tests, I simplified the question to this piece of code: <html> <head> <script type="text/javascript"> function sub() { alert ("MIC!"); return false; } </script> </head> <body> <form method = "post" id = "form1" onsubmit =

I am wanting to run javascript user validation on some textbox entries. The problem I'm having is that my form has the action of going to a new page within our site, and the onsubmit attribute never runs the javascript function. Is there a better solution, or one that works with the following code: NOTE: the javascript file is written correctly and works if you switch the action to checkRegistration() . It is merely an issue with running both action and javascript. <form name="registerForm" action="validate.html" onsubmit="checkRegistration()" method="post">  <!-- and

Should jQuery's $(form).submit(); not trigger onSubmit within the form tag?

I have the following: <script type="text/javascript"> function CancelFormButton(button) { $(button.form).submit(); } </script> <form onsubmit="alert('here');"> <input type="button" value="Cancel" onClick="CancelFormButton(this);" /> </form> When I click the "Cancel" button, the onsubmit from the form tag is not triggered. This line instead submits the form successfully: $(button.form).submit(); but skips the alert('here'); within the onsubmit in the form tag. Is this correct or am I doing something wrong? By the way, in this case, I want this functionality, but I'm just wondering if I'm going
