Same page processing

How can process a form on the same page vs using a separate process page. Right now for signups, comment submissions, etc I use a second page that verifies data and then submits and routes back to home.php. How can I make it so that on submit, the page itself verifies rather than using a second page. You can tell the form to submit to the PHP's self, then check the $_POST variables for form processing. This method is very good for error checking as you can set an error and then have the form reload with any information the user's previously submitted still in tact (i.e. they don't lose their

Form onsubmit versus submit button onclick

由 徘徊边缘 提交于 2019-11-29 03:42:50
UPDATE From @BrendanEich ‏ @mplungjan onclick of submit just falls out of that being a button; form onsubmit is clearly better. Which would be the reasons to ever use the onclick of a submit button to determine whether or not the form should be submitted? I believe strongly that to execute something before submit and cancel the submit in case of error, the form's onsubmit event is the obvious place to put it If you use the onclick of a submit button and later decide to use type="image" the event handler will fail in many browsers if you change the submit to a button, you will have to add a

How to enable a disabled text field?

由 ﹥＞﹥吖頭↗ 提交于 2019-11-29 01:29:07
I wanna know how do I enable a disabled form text field on submit. Also I wanna make sure if user goes back to form or click reset field will show again as disabled. I tried to use document.pizza.field07.disabled = false ; It does disables the field, by clicking reset or hitting back button still keeps it enable. Please guide. To access this element in a more standard way, use document.getElementById with setAttribute document.getElementById("field07").setAttribute("disabled", false); EDIT Based on your comment, it looks like field07 is a name , not an id. As such, this should be what you want

How can I refresh a form page after the form submits to _blank?

由 岁酱吖の 提交于 2019-11-28 23:38:29
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 want the form page to reload, or at least reset all fields. I've tried <form onsubmit="location.reload()".

Setting onSubmit in React.js

由 ▼魔方 西西 提交于 2019-11-28 18:05:56
问题 On submission of a form, I'm trying to doSomething() instead of the default post behaviour. Apparently in React, onSubmit is a supported event for forms. However, when I try the following code: var OnSubmitTest = React.createClass({ render: function() { doSomething = function(){ alert('it works!'); } return <form onSubmit={doSomething}> <button>Click me</button> </form>; } }); The method doSomething() is run, but thereafter, the default post behaviour is still carried out. You can test this

Form OnSubmit to wait jQuery Ajax Return?

由 ≡放荡痞女 提交于 2019-11-28 05:55:34
问题 I want to trigger $.ajax on form onsubmit and return true only after Ajax return is something valid. For example: <form id="myForm" onsubmit="return ajaxValidation();"> <input id="myString" name="myString" type="text" /> <input type="submit" value="Submit" /> </form> In Javascript: function ajaxValidation() { $.ajax({ async: false, type: "POST", url: "ajax.php", data: { myString: $("#myString").val() } }).success(function( response ) { alert(response); //Got 'ok' if (response=="ok") { return

onSubmit returning false is not working

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 = "return sub()"> input: <input type="text" name="input1" > <a href="#" onClick="document.getElementById(
