the alert class shows everytime, any idea why?
The use of $("input") here is unusual. That selector will pull back all elements on the page that are <input>s, which is almost certainly not what you mean. (If there are other inputs on the page, you might get exactly what you're describing.) Use a more precise selector, like $("#text"), and maybe use debug to output the value of val().length so you know what you're evaluating.
(On a side note, "text" is not a very useful name for a text input, and your else-if seems redundant, but they probably aren't causing problems in your code.)

I'm learning Javascript and now I'm making to-do list.I've finished the basic one but I want to add the delete button which delete all the checked lists to my to-do list.
I've tried some ways that I came up with and they all failed and I cannot find the answer by googling.
How can I do this ? If there is someone who know, please teach me . I'd appreciated if you could show me how.
this is my code ↓ the error happened saying cannot read property 'parentElement' of null at Object.deleteAll
deleteAll: function() {
let taskListItem, checkBox, checkBoxParent;
for (i=0; i<this.taskListChildren.length; i++){
taskListItem = this.taskListChildren[i];
checkBox = taskListItem.querySelector('input[type = "checkbox"]:checked');
checkBoxParent = checkBox.parentElement;
checkBoxParent.remove();
}
document.getElementById('deleteChecked').addEventListener('click', () => {
tasker.deleteAll();
});
🙏

You can use the jQuery library and solve it as follows.
Step 1) Define in your html button element:
<button id="button" onclick="reset()"> RESET </button>
Step 2) define the 'reset ()' function, like this
function reset()
{
$("input:chceckbox").removeAttr("chcecked");
}
Good luck!!
I am trying to create a prompt dialog box using alertifyjs that has multiple input boxes. I have managed to create the dialog box to show the multiple boxes but I cant seem to make a reference to the inputs that user provides.
I want to write if statement that carries out action based on user input when they press OK. However, the OK button doesnt seem to be working and also the if-statements don't work as well. I am not sure what I might be doing wrong, can someone please help me.
Below is my code:

In your script you call a function named updateListItems(inpOneVal,inpTwoVal);
As that function is not declared anywhere, it errors, so with that temporarily commented out, it works.

Can you please tell me how to show an error message on submit button click ?.I am getting an error message after running the program (when I write required :true). I need to show an error message when a user submits the form. I am using this plugin https://github.com/McNull/angular-febworms
Can we get onchange event of select field ?
In my example a red border is displayed when I run the application. I don't want this. I need this when a user clicks the 'submit' button

But need to blur event to validate or onchange event ?
Since your form name is 'form.state' and your field name is 'required' (which is a bit confusing by the way, you may want to change that), you can get useful information about your validation state with the following expressions in the scope of your form:
form.state.required.$error // yields something like { "required": true, "pattern": false }
form.state.required.$valid // yields a boolean
form.state.$error
form.state.$valid
I haven't heard of a way of knowing whether a form has already been submitted or not. My best shot would be to add some state for this in the controller :
$scope.errorShown = false;
$scope.showErrorMessage = function(){
$scope.errorShown = true;
};
And in your HTML :
<div class="form-actions">
<a class="btn btn-primary" ng-disabled="form.state.$invalid" ng-click="(form.state.$valid ? frmCtrl.save() : showErrorMessage())">Save changes</a>
</div>
<div ng-if="errorShown && form.state.$invalid">
Your form is not valid.
</div>

I'm using asp.net web forms. I have DynamicDataField with some jquery.mobile widjets:

///etc, several same divs
this DynamicDataField(Search.ascx) I place on my Main.Master padge:

The problem is: after adding
<script src="http://code.jquery.com/mobile/1.3.2/jquery.mobile-1.3.2.min.js"> </script>
all my project starts behave strange. All fonts etc are like as in jquery.mobile widjet, some javascript methods don't work. So. How can I isolate jquery.mobile-1.3.2.min.js? I want it to be used ONLY in Search.ascx.
Any suggestions? sry, i'm new in jquery:)
By default, jQuery Mobile enhances everything on the page. You can use data-enhance="false on the page body, and just use data-enhance="true" on the control that you want to enhance.
See the docs for more info.
In this case, you need to tell JQM not to to auto-initialize pages. You should do that once mobileinit fires to apply global changes, after loading jQuery and before loading jQuery mobile JS libraries.
Nevertheless, bu doing so, you will need to manually enhance JQM elements (widgets).
<head>
<!-- jQuery.js here -->
<script>
$(document).on("mobileinit", function () {
$.mobile.autoInitializePage = false;
});
</script>
<!-- jQuery Mobile.js here -->
</head>
I have a simple login form like below, with an attached jQuery script. I'm trying to make some simple client-side form validation using jQuery. I can't seem to get the blur event to fire, however. I can't think of what I'm doing wrong, I've tried using '.on('blur', fn(){})' but that doesn't work either. Please help!
Here's my HTML file:

<body>
<div id="wrapper">

<h1>Ship Catalogue</h1>

<div id="mainContent">
<form id="LoginForm" name="LoginForm" method="post" action="<?php echo $_SERVER['PHP_SELF']; ?>">
<div class="FormRow"><label for="Username">Username:</label><input type="text" name="Username" id="Username" /><p id="userErrors"><?php echo $userErrors; ?></p></div>
<div class="FormRow"><label for="Password">Password:</label><input type="password" name="Password" id="Password" /><p id="passwordErrors"><?php echo $passwordErrors; ?></p></div>

</form>
</div>

</div>
</body>
</html>
And here's the loginFormValidation.js script:
$("#Username").blur(function(e){
alert();
if ($("#Username").val() == "") {
$("#userErrors").text("Username must be entered!");
}
});
$("#Password").blur(function(e){
if ($("#Password").val() == "") {
$("#passwordErrors").text("Password must be entered!");
}
});
You need to wrap your events inside jQuery's document.ready function:
$(document).ready(function() {
$("#Username").blur(function(e){
alert();
if ($("#Username").val() == "") {
$("#userErrors").text("Username must be entered!");
}
});
$("#Password").blur(function(e){
if ($("#Password").val() == "") {
$("#passwordErrors").text("Password must be entered!");
}
});
});
Either add your jquery blur code inside
$(document).ready(function() { ...// your blur code here }
OR
at bottom of your page above closing body tag like:
<script type="text/javascript">
//your blur code
</script>
</body>
It works if you add some content to alert. The JS engine threw an error because the alert function was being called with no parameters. I would also recommend binding the event with document.ready()
$(document).ready(function(){
$("#Username").blur(function(e){
alert("something");
if ($("#Username").val() == "") {
$("#userErrors").text("Username must be entered!");
}
});
});
