I want to fire a button's click event when pressing ENTER inside a input and I find it quite difficult with AngularJS.
My view (simplified, updated):
<!doctype html>
<html lang="en" ng:app="test">
<head>
<meta charset="utf-8" />
<title>Test</title>
<link rel="stylesheet" href="css/app.css" />
</head>
<body ng-controller="TestController">
<button ng-click="onButton1Click()" class="btn1">Click Me</button>
<button ng-click="onButton2Click()" class="btn2">Don't click me</button>
<script src="lib/jquery/jquery.js"></script>
<script src="lib/angular/angular.js"></script>
<script src="js/testcontroller.js"></script>
</body>
</html>
My controller for this view:
'use strict';
angular.module('test', [])
.controller('TestController', ['$scope',
function($scope) {
$scope.onButton1Click = function() {
alert("Hello");
}
$scope.onButton2Click = function() {
$('.btn2').click();
}
}])
I simplified all the code to this. When I click on btn2 I get this error
$apply already in progress
No, I can't call $scope.onButton1Click() directly, I must simulate the btn1 click.
You mentioned
fire a button's click event when pressing ENTER inside a input
So if it is safe to assume that you can have a form I would prefer using ng-submit as shown below.
<form ng-submit="clickEventFunction()">
<input type="text"/>
<button type="submit">Click</button>
</form>
Note button type should be submit.
This took me a while to figure out (lots of fiddles).
<form id="nowsorting" ng-submit="getData(sc_user)">Now sorting the Soundcloud likes of <input type="text" ng-model="sc_user"><input type="submit" value="Sort"></form>
Make a form and use ng-submit to fire the event (likely a function).
Then create two inputs (one is "text" and the other "submit").
Then pushing enter should fire the ng-submit event/function.
I think, you just have to call your $scope.onButtonClick()
Please check this Plunker
$scope.onKeyPress = function($event) {
if ($event.keyCode == 13) {
$scope.onButtonClick();
}
};

Problem:I am assigning a div to the content property of a kendo tooltip... problem is, when I attached the tooltip... the div is sitting there, and the tooltip does not REALLY wire up until I hover over the element I attached it to... you can see in my code below how this is not working... paste into a kendo dojo, and seee.... just click the button (DO NOT HOVER over the text box yet).. then you will see the div show up, and when you hover over the text box, it will do what it's supposed to do... I made a workaround , which is commented out... but it flashes for a second... is there a way to just make the tooltip wire up and hide the content div?

div1.text(text1.value);

var div1 = $("#toolTipDiv");
window.toolTipEl = $("#text1");
kendo.bind($("#view"), viewModel);
window.toolTipEl.kendoTooltip({
content: div1, position: "top",autohide:true
});
</script></body>
</html>
The div shows up because it is visible and you just made its contents non-blank. Once the tooltip is shown once, kendo takes over control and wraps it in another div that it hides and shows as necessary.
Note that "aria-hidden: true" does not actually hide the div...it is simply a directive to screen-readers...you still have to actually use real CSS to hide the div.
You need to ensure that the div is hidden initially(before kendo wraps it) and remove the display: none; once you "hand it off" to kendo.
Or...hide the div and set the content to a function that just returns the content of the div instead of binding to the div itself, i.e.
<div id="toolTipDiv" aria-hidden="true" style="display: none"></div>
...
updateTooltip: function () {
div1.text(text1.value);
}
...
window.toolTipEl.kendoTooltip({
content: function(e) {
return div1.text();
},
Example: http://dojo.telerik.com/#Stephen/iqaLA
Update
Turns out that the content only gets called the first time the tip is shown for the element, not every time the tooltip is shown, so dynamic changes to the contents (or even the input's title attribute) don't change the tooltip.
So, ignore my answer and try this: http://www.telerik.com/forums/dynamic-content-de3951ae5752

</script>
</body>
I want to call the send method defined in new Vue when the form is submitted ,
But when i submit the form, page is reloading.
I have created a Vue object and linked it to the chat element.
I guess e.preventDefault() is not working.
Interesting, I just helped somebody with a similar issue, the syntax for Vue.2.0 is v-on:submit="send" not v-on="submit: send". Vue already has a way stop the form submitting which is: v-on:submit.prevent so you don't need the e.preventDefault, you would get:
<form v-on:submit="send" v-on:submit.prevent>
or a shorter version:
<form v-on:submit.prevent="send">
There are a few more issues here, so I will go through them for you:
Firstly, you are never submitting the form. To submit a form you need a submit input, not a button:
<input type="submit" value="Send" />
However, from what I can see it's likely you don't even need a form, and can simply use a button with v-on:click:
<div>
<input v-model="message">
<button v-on:click="send">Send</button>
</div>
And then get what was submitted from the view model:
send: function()
{
alert(this.message);
}
You should also use the console (under developer tools in your browser) and log any output rather than alert (console.log(this.message)), because it will also sniff out any general errors with your code - for example I can see that you also have a typo (the same one I always make) it's data not date:
data: {
message: ''
},
Okay, what about this
<form #submit.prevent="send">
<input v-model="message">
<button>Send</button>
</form>
And then you can remove preventing default browser action from your send() method
I am trying to send an xAPI statement after someone submits a their full name and email address through a form. In addition to sending the statement I would like to display a video.html page whereby they can watch a video. I know that there is an example of this on GitHub but I'm trying to do a much simpler example on my own. Can someone have a look at my attempt below and tell me why it is not working. Thanks very much.

Your script at the top of the page is being executed when the page loads, but the form element with the button hasn't been set as the property of the button yet because that part of the DOM hasn't been parsed. If you check the console in your browser you'll see an error such as:
Uncaught TypeError: Cannot read property 'form' of null
Move the <script> block that is currently in the <head> to the bottom of the <body> and it should work.
I have a simple file to test onclick function which I copied straight from w3schools' example. It works fine in the Tryit editor, but the button with the onclick function does nothing when I place it on my server.
<!DOCTYPE html>
<html>
<head>

function open_win()

window.open("http://www.<valid address>");

<body>
<form>
<input type="button" value="Open Window" onclick="open_win()">
</form>
</body>
</html>
Where should I look first?
It does work for me and it is valid code, so I don't know why it's not working for you. But here's an alternative:
<input ... onclick="window.open('http://www.<valid address>');">
^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
If it still doesn't work then check if you have JavaScript enabled in the browser you are using to access your server.
I am using jquery validation engine in my project on the input fields.
The code structure is like this
<form>
<input/>
<input/>
</form>
and i validate the fields in keyUp.
Now how do i show the prompt only on the input that has a focus.
or in otherwise how do i validate a single input element that has focus inside a particular form as the validation engine is attached to the form..
I use JavaScript-MVC framework
Please do help me. Thanks in advance
To validate a single input element that has focus inside a particular form on keyup try this

<script src="http://cdnjs.cloudflare.com/ajax/libs/jquery-validate/1.10.0/jquery.validate.min.js"
type="text/javascript"></script>
<script type="text/javascript">
$(function () {
$('form').validate({ onkeyup: false });
$('form').bind('keyup', function () {
$(':focus', this).valid();
});
});
</script>
</head>
<body>
<form>
<input name="one" class="required number"/><br />
<input name="two" class="required" /><br />
<input type="submit" />
</form>
