mouseenter with condition in angular

I have a button in angular:
<button type="button" id="bulkInputButton"
(click)="toggleBulkInput()"
#bulkInputButton>Show
Bulk Input</button>
I want to show different tooltip based on some condition. Basically I want to incorporate this jquery code in the button tag itself:
$("#InputForm button#bulkInputButton").mouseenter(function(e) {
//TODO
if($("#inputTextArea").css("display")=="none") {
toolTip(this,"<font color='#444444'>Note: This is not a replacement for Bulk Upload</font><br><br>On click of this button, it will display text area where user can manually enter data or copy data from excel sheet or from any editor and paste it in bulk input text area.","Bulk Input");
} else {
toolTip(this,"Click to hide bulk input text area.","Bulk Input");
}
});
How can I do this?
Thank you!

You can do with the help of jquery in angular
Your typescript code should be look like.,
toggleBulkInput(){
// get id of elemeneRef
// make your dynamic logic
// call enableToolTip function
}
enableToolTip(id, validationMsg): void {
let $control;
$control = $(id);
$control.attr('data-original-title', validationMsg);
$control.tooltip('show');
}
Inside you html code you can call action method
<button type="button" id="bulkInputButton"
(click)="toggleBulkInput()"
#bulkInputButton>Show
Bulk Input</button>
By this way you can implement dynamic tooltips in angular application

In angular you should "re-thinking" using variables.
I don't know about your tooltip, so, Imagine you has a typical .css
.tooltip {
position: relative;
display: inline-block;
border-bottom: 1px dotted black;
}
.tooltip .tooltiptext {
visibility: hidden;
width: 120px;
background-color: black;
color: #fff;
text-align: center;
border-radius: 6px;
padding: 5px 0;
/* Position the tooltip */
position: absolute;
z-index: 1;
}
.tooltip:hover .tooltiptext {
visibility: visible;
}
And a variable "toogle"
Some like
<button (click)="toogle = !toogle">toogle</button>
<div class="tooltip">
Hover over me
<span *ngIf="toogle" class="tooltiptext"><b>Toogle</b> is true</span>
<span *ngIf="!toogle" class="tooltiptext"><b>Toogle</b> is false</span>
</div>
Makes the "trick", see that all you need is a variable. This variables makes that show one or another tooltip

How to hide/show part of an option tag

I have a select tag with a number of options listed, and I have a button that should display more information to the user, including modifying the options to show more information. So, for example something like this:
Normal View
<option>RegularInfo</option>
Extra View - should be displayed after button click
<option>RegularInfo (ExtraInfo)</option>
I would like to have my button be able to toggle between these two views, but I'm not sure if there is a simple way to do it. One way I've considered is just writing a javascript function to modify the text manually, but then the code gets a bit messy with a lot of string manipulation.
I tried embedding a span with a class inside and then just toggling the class with jQuery like so:
<option>RegularInfo<span class = "extra">(ExtraInfo)</span></option>
//JQuery
$(".extra").toggle();
However, it turns out you cannot embed html elements inside an option tag, so this method didn't work for me.
Is there a way for me to toggle the visibility of part of an option without having to manually set the value of the option using javascript?

Yeah, you can't nest child tags inside of <option> tags. If you don't want to append text with javascript, maybe try a method similar to this one of selecting text inside of your tags and manipulating it (in your case hiding and displaying it): https://stackoverflow.com/a/16585227/7184365

I already did this in the past and you can just copy the codes here just alter it. But the definition here is you need to have a checkbox since checkbox only handles 2 values, on and off.. like a toggle button. You will just redesign the checkbox to a toggle button. But if your don't want to change the design, don't copy the css.
<script>
function clicker(enable){
.. some codes here ..
}
</script>
.switch {
position: relative;
display: inline-block;
width: 60px;
height: 34px;
}
.switch input {display:none;}
.slider {
position: absolute;
cursor: pointer;
top: 0;
left: 0;
right: 0;
bottom: 0;
background-color: #ccc;
-webkit-transition: .4s;
transition: .4s;
}
.slider:before {
position: absolute;
content: "";
height: 26px;
width: 26px;
left: 4px;
bottom: 4px;
background-color: white;
-webkit-transition: .4s;
transition: .4s;
}
input:checked + .slider {
background-color: #2196F3;
}
input:focus + .slider {
box-shadow: 0 0 1px #2196F3;
}
input:checked + .slider:before {
-webkit-transform: translateX(26px);
-ms-transform: translateX(26px);
transform: translateX(26px);
}
/* Rounded sliders */
.slider.round {
border-radius: 34px;
}
.slider.round:before {
border-radius: 50%;
}
<label class="switch">
<input type="checkbox" <?php echo "onclick='clicker("$someVar")'";
if(!empty($someVar)){
echo " " . "checked";
}
?>
><span class="slider round"></span>
</label>
and of course you need to save the event of the toggle button to the database so if you leave it, it will stay like that. So basically you will also need ajax for that.

An option element cannot have any child elements.
From the HTML 5 draft spec:
Content model: Text.
You can't nest child tags inside of <option> tags, but you can replace the text inside it.
Replacing with pure JS:
function changeOptionText()
{
var select1 = document.querySelector('#select1');
select1.firstElementChild.innerHTML += ' (ExtraInfo)';
}
<select id="select1">
<option>RegularInfo</option>
<option>Other info</option>
</select><br>
<input type="button" value="change option" onclick="changeOptionText()">
Replacing with jQuery:
function changeOptionText()
{
var firstOptEl = $('#select1 option').first();
firstOptEl.html(firstOptEl.html() + ' (ExtraInfo)');
}
<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script>
<select id="select1">
<option>RegularInfo</option>
<option>Other info</option>
</select><br>
<input type="button" value="change option" onclick="changeOptionText()">

Javascript Logic in Extending Search Bar

I've created an expanding search bar: You click on the magnifying glass the input extends out and to the right, click it again and it closes. (See Fiddle Below).
I'm new to the world of JS and I thought this would be a great opportunity to implement some logic. Here's what I;m trying to do:
If the search bar is open and the inner.html is empty, if you click the "search" magnifying glass, I want to prevent the default submission of the form and simply close the search bar
If there is text, I want the form to be submitted.
Right now I've got the elements layered in such a way as to when you click the "search" button for the first time, the bar extends and the z-index of the button drops to one where the actual submit button is higher, but I want to control the functionality a little more.
What I've tried:
I tried creating a function that added an event listener that said, basically, if the bar has a width of 700px (the extended length) and the inner html is empty, bring the z-index of the extend button up back higher than the submit simply close the form. But I can't seem to work the logic out properly.
I'm wondering how in JS you can control the z-index.
Here is the code I tried and did not work. I tried something simply like just alerting when the task I wanted to watch for was done first but it doesn't seem to be working.
Any help would be wonderful.

<div id="wrap">

var search = document.getElementById("myForm").search;
var search_submit = document.getElementById("myForm").search_submit;
function showOpen()
{
if(search.style.width=="700px")
{
alert("OPEN!");
}
};
search.addEventListener("click", showOpen);
showOpen();
HERE IS THE FIDDLE: https://jsfiddle.net/theodore_steiner/7begmkf3/37/

Your issue can be solved using a few basic JavaScript elements (if you're looking to get into basic logic, these are important to know). The JS uses onsubmit, onclick, and some basic form logic. Basically, when you try to submit the form it checks if the form is empty, and if it is, the program refuses to submit the code. I added the new JavaScript to the HTML file:
<script>
function check(){
value = document.forms["myForm"]["search"].value;
if(value == "" || value == null){
alert("please enter a search term");
return false;
}else{
document.getElementById("myForm").submit();
}
}
</script>
<div id="wrap">
<form id="myForm" onsubmit="return check()">
<input id="searchBar" name="search" type="text" placeholder="What are we looking for?" />
<input id="search_submit" value="" type = "submit">
</form>
</div>
fiddle: https://jsfiddle.net/q1L3Lstx/1/
It might also help in the future to look at the required element: http://www.w3schools.com/tags/att_input_required.asp

I saw a couple of issues with the code.
search and search_submit are pointing to the wrong items they can be like this:
var search = document.getElementById("search");
var search_submit = document.getElementById("search_submit");
You could call a function on submit. like this:
<form id="myForm" onsubmit="myFunction(event)">
finally you can work your code inside that function:
function myFunction(e){
if(search.value.length <= 0){
e.preventDefault();
alert('empty');
}
}

Blog / Message - How do I fix that empty message divs will piling on / next to each other and make the close button work?

So I'm making a sort of blog posting system or TODO list, however you want to call it.
I want that the following can happen / is possible:
[Working] The user types something in the textarea
[Working] The user clicks on the button.
[Working] A new div will be created with the text of the textarea.
[Working] The textarea will be empty.
[Not Working] The user has got the choice to delete the post by clicking the 'X' on the right side of each '.post' div.
BUT: If I click on the button when there's nothing in the textarea, there appears an empty div, with only an 'X' close button, no background color either. They appear on the same line as the previous message, so you can get a lot of 'X's next to each other.
AND: Clicking the 'X' close button doesn't do anything. No errors in Firefox console.
If it's not clear enough, run this JSFiddle, click the button and I think you'll understand what I mean:

You appear to have two issues:
1) You don't want a post to be created if the textarea is empty
Simple fix . . . check to see if it is empty, before calling the logic to add the new post (and use jQuery's $.trim() to account for only blank spaces):
$('#button').click(function() {
var text = $.trim($('#poster').val());
if (text !== "") {
$('#posts').prepend("<div class='post'>" + text + "<span class='close-post'>×</span></div>");
$('#poster').val('');
}
});
2) The 'X' buttons are not closing the posts
This also should be a pretty easy fix . . . the reason that they are not working is because the 'X' buttons don't exist when the page is loaded so $('.close-post').click(function() { is not binding to them on page load. You will need to delegate that event binding, so that it will apply to the 'X' buttons that are dynamically added after the page is loaded.
Now, not knowing what version of jQuery that you are using (I can't access jsFiddle from work), I'll point you to the right place to figure out the correct way to do it: https://api.jquery.com/on/
If it is jQuery 1.7 or higher, you would do it like this:
$("#posts").on("click", ".close-post", function() {
$(this).parent().hide();
});
If your version is earlier than that, then investigate the jQuery .delegate() and .live() methods to determine which is the right one to use for your code..

Try this:
$(document).ready(function() {
$('#button').click(function(event) {
event.preventDefault();
var text= $('#poster').val();
if (text === '') {
alert('Nothing to post!');
return;
}
$('#posts').prepend("<div class='post'>" + text + "<span class='close-post'>×</span></div>");
$('#poster').val('');
});
$('#posts').on('click', '.close-post', function() {
$(this).closest('.post').fadeOut();
});
});
JSFiddle

The way you are doing this, the user will only ever see what they are posting - if you're trying for a chat type where users talk to each other then you will need to store what is being typed on the server side and refresh the screen using something like ajax
but in response to your question, you need to bind the close click like this:
$( "#posts" ).on( "click", ".close-post", function() {
$(this).parent().hide(); // $(this) is the clicked icon, the way you did it above wouldn't as if it had the dollar, it would close all .close-post parents
});
See the part about delegated events: http://api.jquery.com/on/

This is in my HTML page. I have negative top to show and hide forms for better views.
Please clear me the following doubts
1) I have to send the data to server when user submits form. I do client-side and server-side validation. If client-side validation fails, I 'll show the errors in the form itself. If there is any server-side error, how do i show this in the form?
My ideas:
I have to insert some php error tags in the html page and change my filetype to php from html so that if there is any server side error i ll insert the error in those tags.
<span class="error">* <?php echo $emailErr;?></span>
Something like the above.
(or)
Take the user to another php page where user re-enter the details. and handles all the error in the same page.
2) What are the problems with this type of negative top form design?
Please let me know the problems and suitable solutions so that i get clean design. I don't want the code only the idea.

There are couple of ways to do it but I am gonna stay low here by giving more of a hint to what you can do.
Using AJAX to submit form?
If the validation fails in PHP...
Create an associative array containing all the error messages and a key like submitError set to TRUE.
json_encode the array and die or return it.
In your JavaScript AJAX success callback, check for the existence of submitError key in the response.
If true, parse and display all messages from the JSON response you received. Done!
NOT using AJAX?
You can utilize $_SESSION to store the errors and related messages & set a flag for error.
When the page loads/submits, check if $_SESSION contains that flag.
If it does, pull the messages from session and display to the user.
Once displayed, clear those things from $_SESSION
These things can be done for small applications. If you are using some kind of framework like CodeIgniter or Laravel, you may want to check their session flash methods.
About Negative Top Form Design
I don't see much of a problem there unless it's covering up something vital beneath it when opened. Specially on mobile version( if you plan to do that).
