Problem:
I'm trying to implement a dropdown form from a button. However, I'm having issues with the form not staying visible even after the condition is met. I'm new to javascript and css, so bear with me if it's a silly error. Thanks in advance.
What I want to do:
The form will be hidden by default.
When a user hovers over an image button, the form should be shown and hidden after the mouseleave.
If the user clicks the button, then the form should stay visible so that the user can enter the data and sumbit it.
Observation:
The objectives #1 and #2 from above are working as expected.
As opposed to objective #3, the form automatically hides even after the button click.
Unsuccessful Methods:
Using .show() instead of .css("display","block")
Using form:hover to set display:block.
Using setTimeout(hide_function,500) hides the form after 500ms regardless of the button click.
Code:
Here's the link to my jsfiddle that you can use to test it out.
References:
For button click detection.
For changing display property.
Just change data attr:
$('#dropbtn').click(function() {
$(this).data('clicked', 'yes');
$('#loginForm').css('display', 'block');
});

i have modified your code little bit please check with the fiddle
$('#dropbtn').click(function() {
$(this).data('clicked', 'yes');
$('#loginForm').addClass('activate');
});

I'm relying on another plugins javascript that has code for a specific submit event that submits the form after some validation.
I'm not able to change that validation without hacking into that code.
Therefore I've came up with a hack without hacking into that plugin's code.
I'm changing the input type from submit to button type so I can do my own validation without having to take in account for action that is triggered upon submit.
There are two radiobuttons with class .give-gateway. Basically I'm doing this.
HTML (element in form):
<input type="submit" class="give-submit give-btn" id="give-purchase-button"
name="give-purchase" value="Donate Now" data-before-validation-label="Donate
Now">
jQuery:
$('body').on('click', '.give-gateway', check_gateway);
function check_gateway(id) {
//Value from which radiobutton is selected
if (current_gateway == 'swish') {
alert('changing button from ORIGINAL to new. NOW IT SHOULD BE
TYPE BUTTON!!!');
$('#give-purchase-button').prop('id', 'give-purchase-button-
new').prop('type','button');
$('body').on('click touchend', '#give-purchase-button-new', function
(e) {
alert('NEW give purchase button clicked');
//some code...
});
}
else {
alert('changing button from NEW to original. NOW IT SHOULD BE TYPE
SUBMIT!!!');
$('#give-purchase-button-new').attr('id', 'give-purchase-
button').prop('type','submit');
}
}
This works the first time:
From Submit to button
From Button to Submit
From Submit to Button
Step 3 (NOT WORKING (first click on swish gateway work but second time it does not change from submit to button)!? **Why?) **
I've also tried to programmatically add onsubmit to form but the issue there is that other plugins jquery code has a listener for click event on the actual submit - button which means that that code are executed first anyway. I don't want that to happen.
I've figured it out why now. When I click on another gateway the form is loaded with other content. When I go from swish to paypal. It loads content that is dependent of paypal stuff and creates a new submit - button. If I just change from type submit to button it does not affect anything because that change is made before the actual content is loaded (through ajax) and therefore creates a new submit button.
Let's say I have a collection containing 3 elements.
Each element has a corresponding remove button that I would like to initiate a POST to my server. Right now I have it setup so that when "Remove" button is pressed, a confirmation modal pops up with "yes" and "no" buttons. I am using the same modal for each element.
Problem is, when I click "yes" in modal, how can I have it know which remove button I clicked that launched the modal?
Here is a link to a gist containing the problematic code
https://gist.github.com/anonymous/85481507a1171467cae5
I have tried using a suggestion below that implements the following:
$('#hingle_dingle_0').on('click', function(e){
$('#confirmRemoveNetwork').modal('toggle', $(this));
});
$('#confirmRemoveNetwork').on('show.bs.modal', function (event) {
var button = $(event.relatedTarget) // Button that triggered the modal
console.log(button);
});
However this returns an empty set. I can't for goodness sake figure out why it doesn't find the event.
Thanks for any help!
The modal is autoposting because you are opening it with a <button> inside a form with an input. Unless you tell it not to, this will cause a form submit. Simply set the type to button (instead of submit which is default): <button type="button">
You can capture the calling button by tapping into the event thrown when the modal is opened:
$('#confirmRemoveNetwork').on('shown.bs.modal', function (e) {
console.log(e.relatedTarget.id);
});
Finally, be sure your IDs are unique. You cannot have both "remove network" buttons using the same id of removenetworkbtn.
I am working on an application using html and jquery. It has 4 buttons that are used to perform various tasks when i click them. what i want now is to show user the state of the button when mouse hover over it. For example for an ON/OFF button if mouse hover over the button it shows user that button is currently OFF or ON.
one way to do this is to use an alert() but with that each time i go to button it will show an alert which i dont want i just want a simple text etc to be displayed on top of the button when mouse hover over it.
anyone can help me how can i do it ?
Change the text of the button on button hover by using jQuery .hover():
$('button').hover(function(){
$(this).text('ON');
},function(){
$(this).text('OFF');
});
Demo Fiddle
Presuming you already know how to get the state of the button, let's assume you assign that state to a variable named... well, state. :)
Then it's pretty straightforward from there:
$("button").hover(function() { // You may choose a different selector for your buttons
var curButton = this,
$curButton = $(this);
curButton.oldHTML = $curButton.html(); // Cache old button label
$curButton.html(state); // Change button label to reflect state
}, function() {
var curButton = this,
$curButton = $(this);
$curButton.html(curButton.oldHTML); // Restore old HTML
});
I'm updating the user posts via this code:
var auto_refresh = setInterval(function()
{
$('.contenido-publicaciones')
.load("refresh_p.php?search_user="+search_user).fadeIn();
}, 2500 ); //Which is working.
1: <div class="contenido-publicaciones">, all the <div class="this-is-a-post"> div's from refresh.p.php load here every 2,5 seconds.
2: I have a textarea tag inside for each <div class="this-is-a-post"> that refreshes from refresh_p.php.
3: When <div class="contenido-publicaciones"> refreshes, it also refresh the textarea and prevent the user for typing.
4: All of the textareas have the class b_green
I want to clearInterval(auto_refresh) when the user clicks a textarea with the class b_green so another user can send a comment to that post.
I've tried the following:
$(".b_green").click(function(){
clearInterval(auto_refresh);
}); // Didn't work, <div class="contenido-publicaciones"> keep refreshing.
$("textarea").click(function(){
clearInterval(auto_refresh);
}); // Works only when i click a textarea that i have on the top of the page to send posts, but doesn't work when i click a textarea with the class b_green.
$(this).click(function(){
clearInterval(auto_refresh);
}); //This works if i click on b_green textareas, but stop the Interval on every click that the user does on the page, I only want to stop on b_green textareas click.
Is there any error on my code? Any help would be appreciated.
The clicks do not fire because at the time you are binding them there are no textareas or the ones that there are are latter replaced with new ones. These new textareas do not have the onclick handler attached.
You could do either of these:
Add onclick="clearInterval(auto_refresh);" to the code of the textarea that backend sends and get something like:
<textarea onclick="clearInterval(auto_refresh);"></textarea>
Use on to bind the click handler to a higher element that remains on the page like so:
$(".contenido-publicaciones").on('click', 'textarea', function(){
clearInterval(auto_refresh);
});
As I understood your loaded content contains all nodes which you are trying to handle by click.
If so . There is an issue. Because each time you get update you loose click handlers, because DOM has changed. as + you probably have memory leak here from previous "unreachable" handlers
I have modal popup with an overlay written in html / js, everything works fine but if a user tabs enough they can get to the underlying form fields / buttons. Is there any good way of preventing this?
This is a rough idea but I'm hoping to inspire ideas rather than tell you exactly how to do it. I'll use a combination of pseudocode and pseudo-jquery-code:
function showMymodaldExample() {
//Show modal dialog (mymodal) code goes here
//
//Then we bind an event
$(document).bind('mymodal.keydown', function(e) {
if ( currently focussed element is not a child of mymodal ) {
set the focus previous element
}
});
}
And then remember to unbind mymodal.keydown when you destroy/hide the dialog
