Validation of nested forms in angularjs - javascript

I have a main form and within it I have a second form declared with ng-form directive like this:
<form name="settingsForm">
<label for="firstNameEdit">First name:</label>
<input id="firstNameEdit" type="text" name="firstName" ng-model="person.firstName" required /><br />
<ng-form name="addressForm">
<label for="addressEdit">Address:</label>
<input id="addressEdit" type="text" name="address" ng- model="person.address" /><br />
<label for="zipEdit">ZIP code:</label>
<input id="zipEdit" type="number" name="zip" ng-model="person.zip" required /><br />
<button>Save address</button>
</ng-form>
<button>Save</button>
</form>
When I hit submit button all inputs are validated, I wonder if I can validate only firstName for example and not the ng-form because, I want ng-form to be submitted separated on save address, not on save.

First of all you need to disable the default validation of the form as shown by Zohaib Ijaz. You can utilize the validation variable $invalid provided by AngularJS.
<form name="settingsForm" novalidate>
<div>
<label for="firstNameEdit">First name:</label>
<input id="firstNameEdit" type="text" name="firstName" ng-model="person.firstName" required />
<p ng-show="validateMainForm && settingsForm.firstName.$invalid"
class="help-block">You name is required.</p>
<br />
</div>
<ng-form name="addressForm">
<div>
<label for="addressEdit">Address:</label>
<input id="addressEdit" type="text" name="address" ng- model="person.address" />
</div>
<div>
<label for="zipEdit">ZIP code:</label>
<input id="zipEdit" type="number" name="zip" ng-model="person.zip" required />
<p ng-show="validateAddressForm && addressForm.zip.$invalid"
class="help-block">Zip code is required</p>
</div>
<button type="submit" ng-click="submitAddressForm()">Save address</button>
<br/>
</ng-form>
<button type="submit" ng-click="submitMainForm()">Save</button>
</form>
As you have disabled the default validation, the validation happens on click of submit button for the main form as well as the address form. On submit, a flag is set which shows the error block if the field is invalid. There is a flag validateMainForm for the settingsForm and validateAddressForm for the addressForm. When the flag is true, it shows the p element below each input field if it is invalid.
Here is the plunker that demonstrates this.
For more information, you can refer this blog- Angular Form Validation:

You can do something like this
https://jsbin.com/latepo/edit?html,js,output
<form name="settingsForm" novalidate>
<label for="firstNameEdit">First name:</label>
<input id="firstNameEdit" type="text" name="firstName" ng-model="person.firstName" required /><br />
<ng-form name="addressForm" >
<label for="addressEdit">Address:</label>
<input id="addressEdit" type="text" name="address" ng- model="person.address" /><br />
<label for="zipEdit">ZIP code:</label>
<input id="zipEdit" type="number" name="zip" ng-model="person.zip" required /><br />
<button type="submit" ng-click="submit2()">Save address</button>
</ng-form>
<button type="submit" ng-click="submit1()">Save</button>
</form>
angular.module('myapp', []).controller('MyController', MyController);
function MyController ($scope){
$scope.submit1 = function (){
alert('submit1');
};
$scope.submit2 = function (){
alert('submit2');
};
}

Advance search function of google search using javascript but getting some problems

Below is the code of the form using which I'm trying to fetch the value for the query string.
<form id="form1">
<label for="allthesewords"> all these words</label>
<input type="text" id="allthesewords">
<br>
<label for="thisexactwordphrase">this exact word phrase</label>
<input type="text" id="thisexactwordphrase">
<br>
<label for="anyofthese">any of these</label>
<input type="text" id="anyofthese">
<br>
<label for="noneofthese">none of these</label>
<input type="text" id="noneofthese">
<br>
<input type="submit" value="Advance Search" onClick="advanceSearch()">
</form>
This one is the javascript function where I'm building my query string.
function advanceSearch(){
document.getElementById("form1").action="https://www.google.com/search?as_q="+document.getElementById("allthesewords").value+"&as_epq="+document.getElementById("thisexactwordphrase").value+"&as_oq="+document.getElementById("anyofthese").value+"&as_eq="+document.getElementById("noneofthese").value;
return true;
}
So, the actual problem is while clicking on the submit button it must redirect to this url
https://www.google.com/search?as_q=Harvard%20univeristy%20students&as_epq=students%20of%20Harvard%20Univeristy&as_oq=Harvard&as_eq=almamater
However, when I run my code it just redirects to this url:
https://www.google.com/webhp.
Thanks in advance!!!!!
<form action="https://www.google.com/search">
<p>Find page with</p>
<input class="input_bar" type="text" name="as_q" placeholder="all these words">
<input class="input_bar" type="text" name="as_epq" placeholder="this exact word or phrase">
<input class="input_bar" type="text" name="as_oq" placeholder="any of these words">
<input class="input_bar" type="text" name="as_eq" placeholder="none of these words">
<input id="btn" type="submit" value="Advance Search">
</form>
Use it!

Javascript disable submit button unless if all html validations are fufilled

I have a simple form:
<form role="form" enctype="multipart/form-data">
<div>
<div>
<span>Name</span>
<input type="text" placeholder="Estate name..." id="Editname" required />
</div>
<div>
<span>Address</span>
<input type="text" placeholder="Address..." id="Editaddress" required />
</div>
<div>
<span>Upload</span>
<input type="file" placeholder="Upload File..." id="Editupload" required />
</div>
</div>
<div>
<div>
<span>##</span>
<input type="email" placeholder="Email..." id="Editemail" required />
</div>
<div>
<span>Tel</span>
<input type="tel" pattern="^\d{4}\d{3}\d{4}$" id="Editnumber" required placeholder="Phone no..." />
</div>
<div>
<span>##</span>
<input type="submit" class="form-control btn btn-primary" id="EditfileUpload" required />
</div>
</div>
</form>
Each of these fields has required and some sort of validation.
I want to disable the "Submit" button when the user enters for example the email in the right format, the correct length of the phone number etc.
How can I do this with JavaScript?
JQuery validate would be my first choice. If you don't want a 3rd party library, then override the submit button's action.
document.getElementById('EditfileUpload').addEventListener('click', function(e){
e.preventDefault();
// do your validation checks here.
document.forms['myform'].submit();
});

Jquery validate multiple inputs with email

I have a form where i ask the user to input email addresses for an automated email to be sent. I have set both the email inputs to be required and to check for valid email, but it seems to work only for the first one. What am I doing wrong here?
<form class="validate" method="post" id="formLoc">
<div data-role="fieldcontain">
<label for="email-from">from</label>
<input type="text" class="required email" id="email-from" placeholder="from" />
</div>
<div data-role="fieldcontain">
<label for="email-to">to</label>
<input type="text" id="email-to" class="required email" placeholder="to" />
</div>
<div data-role="fieldcontain">
<label for="email-message">message</label>
<textarea id="email-message" cols="100" rows="40"></textarea>
</div>
<div class="email-sent">
<h4></h4>
</div>
<div class="SendEmailButton">
<button type="submit" data-role="button" data-icon="forward" data-inline="true"
data-mini="true" data-theme="c">send</button>
</div>
</form>
Here's a fiddle with the problem : http://jsfiddle.net/bobby5193/8dHg9/544/
Add the name attribute to both input fields.
<input type="text" name="email-from" class="required email" id="email-from" placeholder="from" />
<input type="text" name="email-to" id="email-to" class="required email" placeholder="to" />
<textarea name="email-message" id="email-message" cols="100" rows="40" class="required"></textarea>
Here is a jsFiddle
Update
Here is an updated jsFiddle which has validation on the textarea. I added the name attribute and class="required" to it.
If you want get more than one text box to insert Email like
<ul>
<li>
<input id="emailcheck" type="text" placeholder="Email" name="ToEmails[0]" required />
<input id="emailcheck" type="text" placeholder="Email" name="ToEmails[1]" required />
<input id="emailcheck" type="text" placeholder="Email" name="ToEmails[2]" required />
</li>
</ul>
Now we will get all email address from text box.
var email = $('input[name^=ToEmails]');
console.log(email);

Make form run a javascript function?

How can I make my form run a function when submit is clicked?
<form id="commentForm" name="comment">
<fieldset>
<label for="name">Name <span>(required)</span></label>
<input type="text" class="text" id="name" value="" />
<label for="email">Email <span>(will not be published) (required)</span></label>
<input type="text" class="text" id="email" value="" />
<label for="website">Website</label>
<input type="text" class="text" id="website" value="" />
<label for="message">Message <span>(required)</span></label>
<textarea id="message" class="textarea" rows="10"></textarea>
<input type="submit" name="submit" class="submit" id="submit_btn" value="Submit Comment" action="JavaScript: ajax_add_comment();">
</fieldset>
...
I am trying running the following function:
function ajax_add_comment () {
alert ("testing");
}
Use onclick attribute instead of action.
You could use jQuery, and use the .submit() function.
You can give the form an id and then attach the submit function to it.
Example:
<form id="execute"....
</form>
<script type="javascript">
$("#execute").submit(function(){
alert("i've submitted this form");
});
</script>
make sure you have included the jquery js file.
<script src="http://code.jquery.com/jquery.min.js" type="text/javascript"></script>
You can use the onsubmit event to execute JavaScript code when the form is submitted. For example:
<script>
function ajax_add_comment () {
alert ("testing");
}
</script>
<form id="commentForm" name="comment">
<fieldset>
<label for="name">Name <span>(required)</span></label>
<input type="text" class="text" id="name" value="" />
<label for="email">Email <span>(will not be published) (required)</span></label>
<input type="text" class="text" id="email" value="" />
<label for="website">Website</label>
<input type="text" class="text" id="website" value="" />
<label for="message">Message <span>(required)</span></label>
<textarea id="message" class="textarea" rows="10"></textarea>
<input type="submit" name="submit" class="submit" id="submit_btn" value="Submit Comment" onsubmit="ajax_add_comment();">
</fieldset>
Thank you!

JavaScript validator with 2 submit buttons

I'm using a JavaScript validator from http://www.javascript-coder.com/html-form/javascript-form-validation.phtml. The problem I'm facing is that I have one button that saves the registration (here I need to check for name and last name) and the second button which checks the entire form. However, if I press any button, it checks the entire form.
<form id="ministerial" name="register" action="" method="post">
<label>Title: </label>
<input type="text" name="title" value="" />
<label>First Name: </label>
<input type="text" name="first_name" value="" />
<label>Last Name: </label>
<input type="text" name="last_name" value="" />
<label>Organization: </label>
<input type="text" name="organization" value="" />
...
<input type="submit" name="save" value="SAVE REGISTRATION" />
<input type="submit" name="submit" value="SUBMIT REGISTRATION" />
</form>
<script type="text/javascript">
var frmvalidator = new Validator("ministerial");
frmvalidator.addValidation("title","req","Please enter a title");
frmvalidator.addValidation("first_name","req","Please enter the first name");
frmvalidator.addValidation("last_name","req","Please enter the last name");
frmvalidator.addValidation("organization","req","Please enter the organization");
</script>
Maybe this will work. Add validation for proper input fields onClick:
<form id="ministerial" name="register" action="" method="post">
<label>Title: </label>
<input type="text" name="title" value="" />
<label>First Name: </label>
<input type="text" name="first_name" value="" />
<label>Last Name: </label>
<input type="text" name="last_name" value="" />
<label>Organization: </label>
<input type="text" name="organization" value="" />
...
<input type="submit" name="save" value="SAVE REGISTRATION" onclick="return btnSave_click();" />
<input type="submit" name="submit" value="SUBMIT REGISTRATION" onclick="return btnRegister_click();" />
</form>
<script type="text/javascript">
var frmvalidator = new Validator("ministerial");
function btnSave_click(){
frmvalidator.clearAllValidations();
frmvalidator.addValidation("first_name","req","Please enter the first name");
frmvalidator.addValidation("last_name","req","Please enter the last name");
return true;
}
function btnRegister_click(){
frmvalidator.clearAllValidations();
frmvalidator.addValidation("title","req","Please enter a title");
frmvalidator.addValidation("organization","req","Please enter the organization");
return true;
}
</script>
I guess you will need to write a custom validation function
