How to check input text into web form? java script - javascript

how to check input text before POST operation? it must be numbers only
<form method="post" action="credit.php">
Сумма кредита: <input type="text" name="sum"> <br />
первый взнос: <input type="text" name="pv"> <br />
Срок: <input type="text" name="srok"> <br />
Процентная ставка: <input type="text" name="percent"> <br />
<input type="submit">
</form>
sorry for my bad english.

Use some kind of javascript..
<form method="post" action="credit.php" onsubmit="validateForm()">
<input type="text" name="pv" id="pv"> <br />
....
</form>
<script type="text/javascript">
function validateForm() {
var result = /^\d+$/.test(document.getElementById('pv').value);
return result
}
</script>
If your onsubmit returns false, the form won't go. If it returns true, the form will submit.

Jquery not getting form data from forms with that same class name

I'm not getting form values on submit of two forms with the same class.
When I submit one of the forms,
a) Jquery submit event is called but values are empty
b) the submit event is skipped and I'm taken right to the php file where I enter the info into a database
My Jquery
$(document).ready(function(){
$('body').on('submit', '.newStaff', function(event) {
event.preventDefault();
var firstName= this.firstName.value;
// do other stuff
//complete AJAX call
});
});
My forms
<form class="newStaff" method="post" action="insertStaff.php">
<input type="text" name="firstName" />
// use other inputs.....
<input type="submit" value="submit" />
</form>
<form class="newStaff" method="post" action="insertStaff.php">
<input type="text" name="firstName" />
// use other inputs.....
<input type="submit" value="submit" />
</form>
Am I not binding correctly? Haven't had issues like this before. I've always been able to get unique input values based on the form that was submitted.
my be you can use function eq jquery for this
$(function() {
$('body').on('submit', '.newStaff', function(event) {
event.preventDefault();
var firstName = $('.newStaff input[name="firstName"]').eq(0).val();
alert(firstName);
});
});
<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script>
<form class="newStaff" method="post" action="insertStaff.php">
<input type="text" name="firstName" value="1 2 3"/>
<input type="submit" value="submit" />
</form>
<br/>
<form class="newStaff" method="post" action="insertStaff.php">
<input type="text" name="firstName" value="a b c"/>
<input type="submit" value="submit" />
</form>

Validating messages before submit

I'm making a html5 application which require all fields to be filled in before the submit button can be clicked.
What I want to do now is give an alert if a textbox is not filled in, the problem is that my submit button is disabled until all fields are filled in, so I can't really add an alert to that button.
Any idea's on how to solve this?
I want it so that after filling in the final textbox the submit button becomes available without first having to click on it.
Note that the 'required' does not work.
I have the following code:
HTML:
<form id="winForm">
<p>
<input type="text" id="name" name="name" required />
</p>
<p>
<input type="text" id="vorname" name="vorname" required />
</p>
<p>
<input type="text" id="email1" name="email1" required />
<label id="atteken" >#</label>
<input type="text" id="email2" name="email2 " required />
<textarea id="fullemail" name="fullemail"></textarea>
</p>
<p>
<input type="text" id="telefon" name="telefon" onclick="generateFullAdress()" required />
</p>
<p>
<input type="text" id="firma" name="firma" required />
</p>
<p>
<input type="submit" id="submitBtn" onclick="sendTheMail()" value=" ">
</button><div id="loading"><img src="images/loadingBar.gif" id="load"></img></div>
</p>
</form>
Jquery/JS
<script type="text/javascript">
function generateFullAdress() {
document.getElementById('fullemail').value =
document.getElementById('email1').value + '#' +
document.getElementById('email2').value;
}
</script>
<script>
var $input = $('input:text'),
$register = $('#submitBtn');
$register.attr('disabled', true);
$input.keyup(function() {
var trigger = false;
$input.each(function() {
if (!$(this).val()) {
trigger = true;
}
});
if(trigger) {
$register.attr('disabled',true);
}else {
$register.removeAttr('disabled');
}
});
</script>
Help would greatly be appreciated.
Thanks!
If you have a form as such:
<form id="form">
...
</form>
You can use the following jQuery code to do something before the form is submitted:
$(function() {
$('#form').submit(function() {
// DO STUFF
return true; // return false to cancel form action
});
});
OR
perform the samething with the onsubmit event like
<form action="youraction" onsubmit="validatefunction" method="post">

Changing 2 hidden input fields on select

I have a form that is need to be passed to my CRM.
the form is simple and contains 2 important fields that defines under what category the data will be received in my crm.
<form method="post" action="http://api.leadmanager.co.il/v1/submit" id="lm_form">
<input type="hidden" name="lm_form" value="5750" />
<input type="hidden" name="lm_key" value="cc0ce4fe280e46e986e5716f9feedaab" />
<input type="hidden" name="lm_tyt" value="" />
<input type="submit" value="submit"/>
</form>
I want to add a drop down list with 2 options first will send the form i mentiond above as is.
the second will modify the values of "lm_key" and "lm_form" to other values.
Plain JS code can be like this. But I would advice you to use some JS library like JQuery, AngulerJS or another one.
<form method="post" action="http://api.leadmanager.co.il/v1/submit" id="lm_form" name="form">
<input type="hidden" name="lm_form" value="5750" />
<input type="hidden" name="lm_key" value="cc0ce4fe280e46e986e5716f9feedaab" />
<input type="hidden" name="lm_tyt" value="" />
<select name="selectField" onchange="changeValues()">
<option value="1">1</value>
<option value="2">2</value>
</select>
<input type="submit" value="submit"/>
</form>
<script>
function changeValues() {
form.lm_key.value = form.selectField.value;
form.lm_form.value = form.selectField.value;
}
</script>

Change value of input and submit form in JavaScript

I'm currently working on a basic form. When you hit the submit button, it should first change the value of a field, and then submit the form as usual. It all looks a bit like this:
<form name="myform" id="myform" action="action.php">
<input type="hidden" name="myinput" value="0" />
<input type="text" name="message" value="" />
<input type="submit" name="submit" onclick="DoSubmit()" />
</form>
And this is how far I've come with the JavaScript code. It changes "myinput"'s value to 1, but it does not submit the form.
function DoSubmit(){
document.myform.myinput.value = '1';
document.getElementById("myform").submit();
}
You could do something like this instead:
<form name="myform" action="action.php" onsubmit="DoSubmit();">
<input type="hidden" name="myinput" value="0" />
<input type="text" name="message" value="" />
<input type="submit" name="submit" />
</form>
And then modify your DoSubmit function to just return true, indicating that "it's OK, now you can submit the form" to the browser:
function DoSubmit(){
document.myform.myinput.value = '1';
return true;
}
I'd also be wary of using onclick events on a submit button; the order of events isn't immediately obvious, and your callback won't get called if the user submits by, for example, hitting return in a textbox.
document.getElementById("myform").submit();
This won't work as your form tag doesn't have an id.
Change it like this and it should work:
<form name="myform" id="myform" action="action.php">
Here is simple code. You must set an id for your input. Here call it 'myInput':
var myform = document.getElementById('myform');
myform.onsubmit = function(){
document.getElementById('myInput').value = '1';
myform.submit();
};
No. When your input type is submit, you should have an onsubmit event declared in the markup and then do the changes you want. Meaning, have an onsubmit defined in your form tag.
Otherwise change the input type to a button and then define an onclick event for that button.
You're trying to access an element based on the name attribute which works for postbacks to the server, but JavaScript responds to the id attribute. Add an id with the same value as name and all should work fine.
<form name="myform" id="myform" action="action.php">
<input type="hidden" name="myinput" id="myinput" value="0" />
<input type="text" name="message" id="message" value="" />
<input type="submit" name="submit" id="submit" onclick="DoSubmit()" />
</form>
function DoSubmit(){
document.getElementById("myinput").value = '1';
return true;
}
My problem turned out to be that I was assigning as document.getElementById("myinput").Value = '1';
Notice the capital V in Value? Once I changed it to small case, i.e., value, the data started posting. Odd as it was not giving any JavaScript errors either.
I have done this and it works for me.
At first you must add a script such as my SetHolderParent() and call in the html code like below.
function SetHolderParent(value) {
alert(value);
}
<input type="submit" value="Submit" onclick="SetHolderParent(222);" />
You can use the onchange event:
<form name="myform" id="myform" action="action.php">
<input type="hidden" name="myinput" value="0" onchange="this.form.submit()"/>
<input type="text" name="message" value="" />
<input type="submit" name="submit" onclick="DoSubmit()" />
</form>
This might help you.
Your HTML
<form id="myform" action="action.php">
<input type="hidden" name="myinput" value="0" />
<input type="text" name="message" value="" />
<input type="submit" name="submit" onclick="save()" />
</form>
Your Script
<script>
function save(){
$('#myinput').val('1');
$('#form').submit();
}
</script>

Pass data to a FORM and auto submit it

The thing I'm trying to have is a JQuery/JavaScript code that will automatically pass some data from facebook to a form (basically the form doesn't need to be shown). so the first part is ready (the part that pulls the data from facebook).
window.fbAsyncInit = function() {
FB.init({appId: 'xxxxxxxxxxxxxxx', status: true, cookie: true, xfbml: true});
};
FB.Event.subscribe('auth.login', function(response) {
if (response.session) {
FB.api({
method: "fql.query",
query: "SELECT name,email FROM user WHERE uid = " + response.session.uid
}
Now i need to insert the name and the email to the inputs with name="name" and name="email" and auto submit the form.
Thanks in advance!
EDIT: here is the form:
<form method="post" class="af-form-wrapper" action="http://www.aweber.com/scripts/addlead.pl" >
<input type="hidden" name="meta_web_form_id" value="XXXXXXXX" />
<input type="hidden" name="listname" value="XXXXXX" />
<input type="hidden" name="meta_adtracking" value="XXXX" />
<input type="hidden" name="meta_message" value="1" />
<input id="awf_field-22176678" type="text" name="name" class="text" value="" tabindex="500" />
<input class="text" id="awf_field-22176679" type="text" name="email" value="" tabindex="501" />
<input name="submit" class="submit" type="submit" value="Submit" tabindex="502" />
<div class="af-clear">
</form>
EDIT 2: I need to do something like this just simplified with jQuery:
<?php
$formcode = '<form method="post" action="http://www.aweber.com/scripts/addlead.pl" >
<input type="hidden" name="meta_web_form_id" value="864136470" />
<input type="hidden" name="listname" value="fbu-ppv-mmoney1" />
<input type="hidden" name="meta_adtracking" value="FB_Ultralizer_PPV" />
<input type="hidden" name="meta_message" value="1" />
<input id="awf_field-22176678" type="text" name="name" class="text" value="" tabindex="500" />
<input class="text" id="awf_field-22176679" type="text" name="email" value="" tabindex="501" />
<input name="submit" class="submit" type="submit" value="Submit" tabindex="502" />
</form>
'; ?>
<script type="text/javascript">
customar_formcode="$formcode";
customar_formcode=customar_formcode.replace("{email}", user.email);
customar_formcode=customar_formcode.replace("{name}", user.name);
document.getElementById(\'form\').submit();
</script>
Use Jquery's POST to send the data without the need for the markup for a form and using auto submits:
$.ajax({
type: 'POST',
url: url,
data: data,
success: success,
dataType: dataType
});
EDIT:
If you have already got the form setup in the DOM you should just fill it in with JavaScript and submit it with JavaScript
To change the input values use Jquery like so:
$('input[name$="name"]').val('value');
once all the inputs are set to how you want them you can submit the form using this:
if you have the ID form on your form then you can use code like
$('#form').submit();
Hope this helps
with jquery you can pass all data of form at once with something like:
var data = $(#formID).serialize();
