I have two forms in one page and i would like to validate each form separately DEPENDING on what the user fills. So basically the user must fill only ONE form and NOT both of them...SO basically if the user fills up form number 1, the validation will be on form 1 ONLY..
Below please find the code of both forms:
<form action="/registration.flow" method="post" id="formElem1" name="formElem1" autocomplete='off'>
<label for="Name_First">First Name:</label>
<input type="text" name="Name_First" id="Name_First" value="" class="required" maxlength="128" />
<label for="Name_Last">Last Name:</label>
<input type="text" name="Name_Last" id="Name_Last" value="" class="required" maxlength="128" />
<button id="registerButton" type="submit">Register</button>
</form>
<form action="/registration.flow" method="post" id="formElem2" name="formElem2" autocomplete='off'>
<label for="Name_First">First Name:</label>
<input type="text" name="Name_First" id="Name_First" value="" class="required" maxlength="128" />
<label for="Name_Last">Last Name:</label>
<input type="text" name="Name_Last" id="Name_Last" value="" class="required" maxlength="128" />
<button id="registerButton" type="submit">Register</button>
</form>
Can someone help me please?
You don't need jQuery specifically to do this. Simple javascript is fine. Call a separate function for the onSubmit of each form.
onSubmit="return validateForm1(this);"
and -
onSubmit="return validateForm2(this);"
Make sure you return true or false depending on if the form passed or failed the validation.
I recommend you the jquery validator . It's easy to use and you can do the two validations separately.

I have 3 fields which I want to validate
<form name='Login' method='post' target='_self'>
<div class="loginPic"...>
<input id="accountLoginField" class="loginEmail" type="text" name="account" value="" placeholder="">
<input id="userLoginField" class="loginUsername" type="text" name="user" value="" placeholder="">
<input id="passLoginField" class="loginPassword" type="password" name="password" value=""
placeholder=""> ....
And I have submit input
<input id="btn_login" type="submit" name="submit" class="buttonM bBlue" value="Connect">
How can I check if these fields are empty and show alert box?
I tried diferent ways that I found here and on other sites, but none of them seems to work... Thank you
You can validate using if and else and check with the values attribute like, this the sample code you can refer for,
function validateform(){
var name=document.myform.name.value;
var password=document.myform.password.value;
if (name==null || name==""){
alert("Name can't be blank");
return false;
}else if(password.length<6){
alert("Password must be at least 6 characters long.");
return false;
}
}
</script>
<body>
<form name="myform" method="post" action="abc.jsp" onsubmit="return validateform()" >
Name: <input type="text" name="name"><br/>
Password: <input type="password" name="password"><br/>
<input type="submit" value="register">
</form>
Likewise, you can check for every field.
The following example will submit to a live test server and the response will be displayed in an <iframe> for demonstration purposes. Client side validation is minimal and of course the server should do the heavy lifting when it comes to validation. Here are the major points:
Make sure the submit button is within the <form>. If for some reason it isn't, add form="*" to it ("*" is the id of <form>). Although it's totally valid for <form> to have a name, an id is more useful so in example <form id='login'...>.
Each field has a required attribute so it can be validated when the "submit" event is triggered, the first blank <input> will have a popup.
The first <input> type has been changed to "email" so validation will stop submission should the user forget #.
<form id='login' action='https://httpbin.org/post' method='POST' target='response'>
<fieldset>
<input name="account" type="email" placeholder="Email address" required>
<input name="user" type="text" placeholder='User name' required>
<input name="password" type="password" placeholder="Password" required>
<input type="submit" value="Connect">
</fieldset>
</form>
<label>These two buttons are outside of form.</label><br>
<input type='submit' form='login' value='Works'>
<input type='submit' value="Doesn't Work"><br>
<iframe name='response'></iframe>
I am trying to automate the login of a web page using vanilla JavaScript.
This is the form on the web page:
<form id="tbb_logon_form" class="login_form" method="post" action="https://www.btopenzone.com:8443/tbbLogon" name="login_form">
<fieldset class="username-field">
<label for="email" id="lbl-email">BT ID</label>
<input type="text" id="username" name="username" class="required" tabindex="3" value="username" placeholder="This is usually your email address">
</fieldset>
<fieldset>
<label for="password">Password</label>
<input type="password" id="password" name="password" class="required" value="password" tabindex="4">
</fieldset>
<input type="submit" value="Login" id="lgnbtn" tabindex="5" id="loginbtn" onclick="var s=s_gi('btiopenzone'); s.linkTrackVars='eVar19,prop50'; s.eVar19='OZ|Home Hub|Landing Page|Account selected:BT Broadband'; s.prop50='OZ|Home Hub|Landing Page|Account selected:BT Broadband'; s.tl(this,'o','OZ|Home Hub|Landing Page|Account selected:BT Broadband');">
<input name="xhtmlLogon" type="hidden" value="https://www.btopenzone.com:8443/tbbLogon">
</form>
The things have tried are:
document.getElementById("lgnbtn").submit();
document.getElementById("lgnbtn").click();
but neither are automating the click of the login button.
Please help me.
You can submit your form using:
document.forms[0].submit();
or
document.forms["login_form"].submit();
I have a question regarding the angular 2 template driven form. I have set up one of this form and I would like to be able to give the user a warning display if one input in a form group is invalid.
For example, let's say I have the following form :
<form class="form" #f="ngForm" (submit)="submit()">
<div class="form-group">
<input type="text" name="firstName" required [(ngModel)]="user.firstName">
<input type="text" name="lastName" required [(ngModel)]="user.lastName">
</div>
<div class="form-group">
<input type="text name="address" required [(ngModel)]="user.address">
</div>
<button type="submit" [disabled]="!f.valid">Submit</button>
</form>
I would like the entire form-group that contains the input "firstName" and input "lastName" to change if either the firstName and/or the lastName is invalid. I know I could do something like that :
<div class="form-group" [class.has-error]="!firstName.valid || !lastName.valid">
<input type="text" name="firstName" required [(ngModel)]="user.firstName" #firstName="ngModel">
<input type="text" name="lastName" required [(ngModel)]="user.lastName" #lastName="ngModel">
</div>
It will works just fine. But here is the tricky part : in this example I only have two inputs with a simple validation rule, so it's easy to check and still readable. But what if I have like 10 inputs to check in a form-group ? I don't want to end up having to manually check the validity of every inputs.
One of the solution I found is to create a subform inside the first one :
<form class="form" #f="ngForm" (submit)="submit()">
<form #subForm="ngForm" [class.has-error]="!subForm.valid">
<input type="text" name="firstName" required [(ngModel)]="user.firstName">
<input type="text" name="lastName" required [(ngModel)]="user.lastName">
</form>
<div class="form-group">
<input type="text name="address" required [(ngModel)]="user.address">
</div>
<button type="submit" [disabled]="!f.valid || subForm.valid">Submit</button>
</form>
Here is a plunker I created to illustrate :
form validation example
But I find it quite ugly, and I'm force to check the two forms to know if there is any problems. So finally my question is : can I set a div as a angular 2 ngForm to be able to validate multiple inputs at once ? Basically is there a better way to perform this kind of validation than creating a subform ? Something like that for example :
<div class="form-group" #names [class.has-error]="!names.valid">
<input type="text" name="firstName" required [(ngModel)]="user.firstName" #firstName="ngModel">
<input type="text" name="lastName" required [(ngModel)]="user.lastName" #lastName="ngModel">
</div>
PS : I know using a function is another solution but it has the same drawbacks : you have to check manually every inputs, depending on the validation rule it can become quite tricky, plus you're losing one of the advantage of using template driven form instead of reactive ones.
Yeah, you can use the ngModelGroup directive for this.
<form class="form" #f="ngForm" novalidate>
<div class="form-group" #fgName="ngModelGroup" ngModelGroup="name" [class.has-error]="!fgName.valid">
<input type="text" class="form-control" name="firstName"
[(ngModel)]="user.firstName"
placeholder="first name"
required>
<input type="text" class="form-control" name="lastName"
[(ngModel)]="user.lastName"
placeholder="last name"
required>
</div>
<div class="form-group">
<input type="text" class="form-control" name="address"
[(ngModel)]="user.address"
placeholder="address"
required>
</div>
<button class="btn btn-primary" [disabled]="!f.valid">Submit</button>
</form>
Hi I have a little problem
I have 3 forms that send different parameters via GET to another page and i have 3 inputs outside all forms that I want to send with form that user chooses to submit.
Inputs with names one, two and three must be send with 1 of that forms.
This is my code:
<input type="text" name="one">
<input type="text" name="two">
<input type="text" name="three">
<form action="process.php" method="get">
<input type="text" name="name">
<input type="submit" value"Process by name">
</form>
<form action="process.php" method="get">
<input type="text" name="adress">
<input type="submit" value"Process by address">
</form>
<form action="process.php" method="get">
<input type="text" name="number">
<input type="submit" value"Process by number">
</form>
All I want to is, when someone submit any form, that three inputs name="(one,two,three)" are send with rest param of form.
EDIT: Just 1 form is submitted!
If you put everything into one form, and use a hidden type value, you can ensure that all values are passed on submit.
<form action="process.php" method="get" id="form1">
<input type="text" name="one">
<input type="text" name="two">
<input type="text" name="three">
<input type="text" name="name">
<input type="submit" name="btnName" value="Process by name">
<input type="text" name="adress">
<input type="submit" name="btnAddress" value="Process by address">
<input type="text" name="number">
<input type="submit" name="btnNumber" value="Process by number">
</form>
Since you are submitting to a PHP page, you can check which of the buttons was pressed with the following code...
if (isset($_POST['btnName'])) {
//do something with name
} else if (isset($_POST['btnAddress'])) {
//do something with adress
} else if (isset($_POST['btnNumber'])) {
//do something with number
}
This is my code:
<form action="/login" method="POST">
<label for="username">Username: </label><input type="text" name="username" id="username">
<label for="password">Password: </label><input type="password" name="password" id="password">
<label for="enc_key">Encryption Key: </label><input type="password" name="enc_key" id="enc_key">
<input type="hidden" name="next_page" value="{{ next_page }}">
<input type="submit" value="submit" id="login_submit">
</form>
Basically I want the username and password to post, but I do not want the enc_key to post. The enc_key is handled by javascript. Is there a way to do this without moving the enc_key input field outside of the form tags?
Try removing the name attribute.
You will still be able to handle your enc_key with the ID, but the input without a name won't be posted.
The easiest thing to do would be to clear that field right before the form posts:
document.getElementById("enc_key").value = '';
