onsubmit

问题 I have an HTML form that allows a user to add an attachment up to X MB. Because connection speeds for users vary, I would like to show a dialog that says something along the lines of "Your request is processing. Do not navigate away from this page. This dialog will close when the form is submitted successfully". Not verbatim but similar. The form posts to itself and is processed with PHP. I am not looking for a progress bar or anything. Just a friendly alert. I have been looking at the jQuery

问题 I have run into an issue with JQuery form submissions and have found no answers anywhere . If someone could shed some light on this, it would be highly appreciated. The issue: The first time I submit the form, it works fine. But if I submit the same form a second time, it sends 2 requests, 3 requests the third time, and so forth. Script: function postInvokeFunctionForm(functionId){ var formId = "#"+functionId+"-form"; var formUrl = "invokeFunction.html?functionId="+functionId $(formId).submit

问题 I'm trying to use Javascript to submit the form's data. Here's the html. <form onsubmit="post();"> //input fields here </form> Here's the Javascript for the post() function. var post = function() { alert('the form was submitted'); return false; } My issue is that the Javascript runs but the form still processes and refreshes the page.. I put the return false; code in hoping it would stop the form from refreshing. 回答1: You will have to put the return false part after the post() function in the

问题 I need to test whether the value of a form's onsubmit is a function. The format is typically onsubmit="return valid();" . Is there a way to tell if this is a function, and if it's callable? Using typeof just returns that it's a string, which doesn't help me much. EDIT : Of course, I understand that "return valid();" is a string. I've replace d it down to "valid();", and even "valid()". I want to know if either of those is a function. EDIT : Here's some code, which may help explain my problem:

问题 I saw this code on the internet, and I'm a little puzzled of what it does, particularly on the onsubmit portion. <form id="generateForm" method="post" action="#" onsubmit="return writeForm(event);"> Am I correct to assume that the onsubmit portion essentially runs writeForm method. The writeForm method then returns some value (ex. string) and then post sends it to where action is pointing to (#). If I'm not mistakent # means it isn't being sent anywhere. On another point, how would I even

问题 I want to perform an onclick and onsubmit at the same time, is this possible? Or if this is bad practice how can I merge the two codes to perform both events? I have this piece of code checking a mandatory field on the form tag: onsubmit="return formCheck(this);" I then have this piece of code on the submit button for the same form: onClick="jQuery.facebox({ ajax: (\'wishlist.php?emailme=true&name=\' + this.form.name.value + \'&country=\' + this.form.country.value + \'&email=\' + this.form
