I'm trying to prevent user from resubmitting the login form with the code below
<button class="submit" ng-disabled="form_login.$submitted" type="submit"></button>
But this will disable the submit button as long as the button is clicked, even when user submit invalid data. What is the right way to stop submit button only after valid information submitted?
You can use ng-required attribute(directive) which will check the dirty state of the element.
Try this:
var app = angular.module('plunker', []);
app.controller('MainCtrl', function($scope) {});
<script src="https://ajax.googleapis.com/ajax/libs/angularjs/1.2.23/angular.min.js"></script>
<!DOCTYPE html>
<html ng-app="plunker">
<head>
<meta charset="utf-8" />
<title>AngularJS Plunker</title>
<script>
document.write('<base href="' + document.location + '" />');
</script>
<link rel="stylesheet" href="style.css" />
<script data-require="angular.js#1.4.x" src="https://code.angularjs.org/1.4.8/angular.js" data-semver="1.4.8"></script>
<script src="app.js"></script>
</head>
<body ng-controller="MainCtrl">
<form action="#" method="post" name="myForm">
Name::
<input type="text" ng-model="name" ng-required='true'>
<input type="submit" ng-disabled="myForm.$invalid" value="Submit">
</form>
</body>
</html>
Live example
Though your question is not clear, But you can try this ,
Here is HTML :
<form action="#" method="post">
Name::<input type="text" ng-model="name" ng-keyup="dirty()">
Address::<input type="text" ng-model="address" ng-keyup="dirty()">
<input type="submit" ng-disabled="error" value="Submit">
</form>
and here is JS :
angular.module('myApp', []).controller('ctrl', function($scope){
$scope.error = true; //Disables button initially
$scope.dirty = function(){
if($scope.name!='' && $scope.address!='')//Check conditions here
{
$scope.error = false; //Enables the button
}
}
});

Suppose a function trigger on Click button
<!DOCTYPE HTML>
<html lang="en">
<!--getElementsByTagName.html-->
<head>
<title>getElementsByTagName.html</title>
<meta charset="UTF-8"/>
<link rel="stylesheet" type="text/css" href="getElementsByTagName.css"/>
<script type="text/javascript">

function getData(){
inputTag=document.getElementsByTagName("input");
divOutput=document.getElementById("output");
alert(inputTag.length);//length of input Tag
for(i=0;i<inputTag.length-1;i++){
if((inputTag[i].value=="") || (inputTag[i+1].value=="")){
alert("Please Enter Value");
}else{
a=inputTag[i].value;
b=inputTag[i+1].value;
}
}
$("#output").css("display","block");
divOutput.innerHTML="<strong>"+a+"<\/strong>";
divOutput.innerHTML+="<br\/>"+"<strong>"+b+"<\/strong>";
}//end function
//]]>
</script>
</head>
<body>
<form action="">
<fieldset>
<legend>Example getElementsByTagName</legend>
<label>Name</label>
<input type="text" id="txtName"/>
<label for="txtName">Password</label>
<input type="password" id="txtPassword"/>
<button type="button" onclick="getData()">
Submit
</button>
</fieldset>
<div id="output">
</div>
</form>
</body>
</html>
Is this right?? $("#output").css("display","block");
This code not working i.e. after click on submit button it doesn't show the output div?
Add this code:
$( "#output" ).on( "click", function() {
this.css("display", "block");
});
This is a problem that can be easily done by declaring a scope function but I was wondering if there is a better way to make this easier
The code is:
<!DOCTYPE html>
<html ng-app="myApp">
<head>
<link rel="stylesheet" type="text/css" href="http://netdna.bootstrapcdn.com/bootstrap/3.1.1/css/bootstrap.min.css">
<script src="http://ajax.googleapis.com/ajax/libs/angularjs/1.4.9/angular.min.js"></script>
<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.2.2/jquery.min.js"></script>
</head>
<body ng-controller="myCtrl">
<input type="checkbox" ng-model="activate" id="activate"> ACTIVATE <br />
<input type="text" ng-model="first" ng-disabled="!activate">
<input type="text" ng-model="second" ng-disabled="!activate">
<!-- <span id="clickMe">Click Me!</span> -->
<script type="text/javascript">
app = angular.module('myApp', []);
app.controller('myCtrl', function($scope, $timeout){
});
</script>
</body>
</html>
So this is the case. The other two fields will be enabled if the checkbox is checked and true and will be disabled if the checkbox is unchecked. What I want is, to make the fields go null or blank automatically upon disabling.
Here is an example: http://plnkr.co/edit/2EPuhRiR9OncV8z7q018?p=preview
Ignoring the fact that it is not a good practice to put too much logic directly in the view, a technical solution would be:
<input type="checkbox" ng-model="activate" id="activate" ng-change="sameAsAbove(first, second); value = null"> ACTIVATE <br />
<input type="text" ng-model="value.first" ng-disabled="!activate">
<input type="text" ng-model="value.second" ng-disabled="!activate">
Im basic developer , just wanted to pass hidden values from my html page in a json array . Following is my code :-
Index.html
<!doctype html>
<html ng-app="plunker" >
<head>
<meta charset="utf-8">
<title>AngularJS Plunker</title>
<script>document.write('<base href="' + document.location + '" />');
</script>
<link rel="stylesheet" href="style.css">
<script src="https://ajax.googleapis.com/ajax/libs/angularjs/1.0.5/angular.js"></script>
<script src="app.js"></script>
</head>
<body>
<div ng-controller="WorkingCtrl">
<h1 ng-bind="vm.heading"></h1>
<form name="myForm" novalidate>
<b> Text: </b>
<input ng-model="form.text" required /><br>
<button ng-click="submitForm()" bng-disabled="myForm.$invalid">Click Me!</button>
</form>
<p ng-bind="showValues"></p>
</div>
</body>
</html>
app.js
var app = angular.module('myApp');
app.controller('WorkingCtrl', ['$scope', '$http', function ($scope, $http) {
$scope.form = {};
$scope.submitForm = function () {
$scope.showValues = JSON.stringify($scope.form);
}
}]);
Now , the value from ng-model="form.text" successfully returns the result as for unhidden input types
{ "text":"What_ever_text" }
but how to send a defined value in array, consisting of hidden input type like :-
<input value="99999" type="hidden" ng-model="form.userid" required />
So , wanted desired output like :-
{ "text":"What_ever_text" , "userid":"99999" }
any solution ?
Note :- The input type should be hidden or any other easier method appreciated. Thanks in advance.
hidden input fields also works same as normal fields only.
see the below code
var app = angular.module('myApp', []);
app.controller('WorkingCtrl', ['$scope', '$http', function ($scope, $http) {
$scope.form = {
text: "some test",
userid: '12312312312'
};
$scope.submitForm = function () {
$scope.showValues = JSON.stringify($scope.form);
}
}]);
<script src="https://ajax.googleapis.com/ajax/libs/angularjs/1.2.23/angular.min.js"></script>
<div ng-app="myApp">
<div ng-controller="WorkingCtrl">
<h1 ng-bind="vm.heading"></h1>
<form name="myForm" ng-submit="submitForm()" novalidate>Text:
<input ng-model="form.text" required />
<br/>
<input type="hidden" ng-model="form.userid" required />
<button bng-disabled="myForm.$invalid">Click Me!</button>
</form>
<p ng-bind="showValues"></p>
</div>
</div>
Is this code correct? I want the 'submit' to validate the field (to make sure a value has been entered) and if this is correct (there is a value) then fade and display.
Currently, the form fades even when no value is entered? I feel I'm missing something really simple here!
<!DOCTYPE html>
<html>
<head>
<meta http-equiv='Content-Type' content='text/html; charset=utf-8' />
<meta http-equiv='X-UA-Compatible' content='IE=edge,chrome=1' />
<link rel='stylesheet' type='text/css' href='styles.css' />
<meta charset="utf-8"-->
<script src="http://code.jquery.com/jquery-2.1.1.min.js"></script>
<script>
function validateForm()
{
var x=document.forms["myForm"]["fname"].value;
if (x==null || x=="")
{
alert("First name must be filled out");
return false;
}
}
</script>
</head>
<body>
<div id="sidebarf">
<form id="sidebarform" name="myForm" onsubmit="return validateForm()" method="post">
<input type="text" id="sidebarusername" name="fname" placeholder="Name" required>
<input type="submit" id="sidebarformsubmit" value="Submit">
</form>
</div>
<script>
$("#sidebarformsubmit").click( function(){
$("#sidebarform").fadeOut("slow", function(){
$("#sidebarf").html("hello " + $("#sidebarusername").val() )
});
});
</script>
</body>
</html>
Judging by your comment on the other answer, you don't care if this actually gets submitted, so you could do the following:
HTML:
<div id="sidebarf">
<form id="sidebarform" name="myForm" method="post">
<input type="text" id="sidebarusername" name="fname" placeholder="Name" />
<input type="submit" id="sidebarformsubmit" value="Submit" />
</form>
JS:
$(document).ready(function() {
$('#sidebarform').on('submit', function() {
if ($('#sidebarusername').val() == '') {
alert('First name must be filled out');
return false;
}
$("#sidebarform").fadeOut("slow", function(){
$("#sidebarf").html("hello " + $("#sidebarusername").val() );
});
return false;
});
});
Working example:
http://jsfiddle.net/3z5x8/
Your validation is bound to the submit event. The click event will always be fullfilled.
Bind your handler to the submit event also
$("#sidebarformsubmit").submit( function(){.....
Unless you are submitting with ajax the form will cause a page refresh also which means your fade and show new html won't work
I'm trying to get text from a text input, append it to a URL, and go to that URL, using Javascript. But when I submit, it appears to just reload the page.
http://jsfiddle.net/E3vv6/
<html>
<head>
<title>Home</title>
<link rel="stylesheet" href="main.css" />
<script type="text/javascript">
function loadSearchResult(searchToLoad) {
window.location = "https://encrypted.google.com/search?q=" + searchToLoad;
}
</script>
</head>
<body>
<form onsubmit="loadSearchResult(document.getElementById('googleBox').value)" method="post">
<fieldset>
<legend>Search</legend>
<input type="text" id="googleBox">
</fieldset>
</form>
</body>
</html>
You need to use event.preventDefault() in the submit function.
Live Demo (click).
Further, inline js (onsubmit in your html) is bad practice for a lot of reasons. Here are some: https://www.google.com/search?q=Why+is+inline+js+bad%3F
If would be better to get a reference to the form with javascript and attach the event listener.
<form id="myForm">
<input type="submit" value="Submit">
</form>
JavaScript:
var myForm = document.getElementById('myForm');
myForm.addEventListener('submit', function(e) {
myFunction();
e.preventDefault();
});
function myFunction() {
console.log('submitted!');
}
You need to prevent the default behaviour of the onsubmit.
You could use return false:
<html>
<head>
<title>Home</title>
<link rel="stylesheet" href="main.css" />
<script type="text/javascript">
function loadSearchResult(searchToLoad) {
window.location = "https://encrypted.google.com/search?q=" + searchToLoad;
return false;
}
</script>
</head>
<body>
<form onsubmit="return loadSearchResult(document.getElementById('googleBox').value)" method="post">
<fieldset>
<legend>Search</legend>
<input type="text" id="googleBox">
</fieldset>
</form>
</body>
</html>
