Is it possible to display message/description when a user chooses an option from a dropdown menu.
Example:
if user chooses "London" from the dropdown menu then we want to display a message from the a database/file relating to "London" ideally using Ajax so not to reload the page.
Thanks in advance.
Yes it is possible. You can add a CSS Class Name to the select in Gravity Forms. This will make it easy for you to add an event listener via your custom Javascript/jQuery. You will need your ajax endpoint of course, but you can add a listener like so:
(function ($) {
$(function () {
// Set your variables here
var select_class = 'my-select-class',
endpoint = '/my_endpoint.php',
notification_class = 'notification-for-select';
var $my_select = $('.' + select_class);
$my_select.parent().prepend('<div class="' + notification_class + '"></div>');
$my_select.change(function (e) {
var my_data = $my_select.val();
$.post(endpoint, my_data, function (data) {
$('.' + notification_class).text(data);
});
});
});
})(jQuery);

Hi I am developing jquery application. I am trying to hide some of the options of choosen dropdown immediately after clicking on it. I am able to hide option but problem is when i click on drodpownbox i can see all the option and if i select any option then required option will hide. What i want is after clicking on the dropdown immediately before showing options i want to hide.
var checkedValues = [];
$("#<%=gdvRegretletter.ClientID %> tr").each(function () {
if ($(this).closest('tr').find('input[type="checkbox"]').prop('checked', true)) {
checkedValues.push($(this).closest('tr').find('td:eq(2)').text().trim());
}
});
$('.limitedNumbSelect').change(function (e) {
//i want to hide here.
$(".limitedNumbSelect option").each(function () {
var val = $(this).val();
alert(val);
//Here i am able to hide.
var display = checkedValues.indexOf(val) === -1;
$(this).toggle(display);
$('.limitedNumbSelect option[value=' + display + ']').hide();
$(".limitedNumbSelect").find('option:contains(' + display + ')').remove().end().chosen();
});
});
I do not have any idea how to achieve it here. Any help would be appreciated. Thank you.
I dynamically create a table full of links of 'actors', which allows to pull the actors information into a form to delete or update the row. The delete button only pops up when you select an actor.
I'm able to click a row, pull the information into the forms, and delete it on first try. However when I attempt to add a new 'Actor' and then delete it, or just delete an existing 2nd row, the button 'Delete Actor' doesn't work. It's only after the first successful delete does the button no longer work.
var addActor = function() {
// Creates a table of links for each added actor with an id based from # of actors
$("#actorsTable").append("<tr><td><a href='' onclick='deleteActor(this)' class='update' data-idx='" + actors.length + "'>" + newActor.fName + " " + newActor.lName + "</a></td></tr> ");
$(".update").off("click");
$(".update").on("click", selectActor);
};
var deleteActor = function(e) {
$("#deleteActor").on('click', function(event) {
event.preventDefault();
var row = e.parentNode.parentNode;
row.parentNode.removeChild(row);
clearForm(actorForm);
actorState("new");
});
};
I'm new to jQuery/javascript, and I'm pretty sure its due to the change in DOM, but I just don't know what to change to make it work.
Here is an Example of it in action
Try
var deleteActor = function(e) {
$("#deleteActor").unbind();
$("#deleteActor").on('click', function(event) {
event.preventDefault();
var row = e.parentNode.parentNode;
row.parentNode.removeChild(row);
clearForm(actorForm);
actorState("new");
});
};
Here is the link for unbind.
http://api.jquery.com/unbind/
The problem is because you're adding another click handler (in jQuery) within the click handler function run from the onclick attribute. You should use one method or the other, not both. To solve the problem in the simplest way, just remove the jQuery code from the deleteActor() function:
var deleteActor = function(e) {
var row = e.parentNode.parentNode;
row.parentNode.removeChild(row);
clearForm(actorForm);
actorState("new");
};
when you add html dynamically you need to attach the event to the parent static element like so:
$("#actorsTable").on("click","a.update", function() {
$(this).closest("tr").remove();
});
I am using Bootstrap's accordion widget to contain several forms i.e. each panel contains one form. When the last panel is selected, the data from the other panels is meant to be posted which will be used to graph the data. However, I am unable to get to the posting part as I cannot figure out which panel is currently selected. I know that this has to do with a class of active or inactive, but I don't think bootstrap's accordion supports that functionality unlike jquery accordion.
I am trying to figure out the first part i.e. check if the user has clicked on the last panel. In my HTML code it has an id of #results. Here's a jsfiddle that demonstrates the issue I am facing. It does not seem to trigger the second alert function when the user clicks on the #results tag, not sure why.
Sample javascript code:
$('#accordion').on('show.bs.collapse', function () {
$('#results').click(function () {
alert("works"); //testing purposes
});
});
Why don't you do?
$('#results').click(function (){
alert("clicked");
});
Just remove the accordion function and you'll get the on click event directly
Is this what you want?
Fiddle: Demo
take this outside the on function
$('#results').click(function (){
alert("clicked");
});
This is an old thread but I wanted to post an answer as the expected result is not suggested.
What you need to do here is to handle the currently selected collapse items with the event handler. If you use the this keyword for this, you can access the values of the selected object (For example only one item in the form).
Here you can get the $(".collapse") element.
You can get the index number of the active item with $(this).parent().index().
Likewise, you can get the id of the active item with $(this).attr('id').
Your jQuery structure would be:
$(".collapse").on('show.bs.collapse', function(){
//0,1,2,etc..
var index = $(this).parent().index();
//collapseOne, collapseTwo, etc..
var id = $(this).attr('id')
//alert('Index: ' + index + '\nItem Id: ' + id );
console.log('Index: ' + index)
console.log('Item Id: ' + id)
if(id === 'collapseFour')
{
var username = $('#username').val();
var email = $('#email').val();
var age = $('#age').val();
//here you can check the data from the form
$("#result").html("<p> UserName: " + username + "</p> <p> EMail: " + email + "</p> <p> Age: " + age + "</p>");
}
});
I've included a working example here for you (jsfiddle).
$('#accordion').on('show.bs.collapse', function (accordion) {
var $activeCard = $(accordion.delegateTarget.children);
});
or
$('#accordion').on('show.bs.collapse', function () {
var $activeCard = $(this.children);
});
I need advice on how to detect which <li> is tap/click by the user, then write the 'ID' of the tap/clicked <li> into Localstorage, then use the saved Localstorage to retrieve data for Detail Page.
I'm new to javascript/jquery, if you can provide some simple example code will be very much appreciated.
I know how to write Localstorage, read Localstorage, get JSON data from server API, generate Loop for Listview with unique ID for each <li>.
What I need is, how to use JS to make <li> clickable (link to Detail Page) and write to Localstorage at the same time.
I have tried:
$('.liClass').click(function() { //block of code to write Localstorage };
But the <li> is not clickable and no key/value written to Localstorage. Not to mention to detect which <li> is clicked (this I have no idea).
Please advice, thank you.
Code update:
//Show restaurant listing - NOTE: This is not first page. Link from other Page.
$('#restaurantList').on("pagebeforecreate", function() {
$.getJSON("http://mydomain.com/api/restaurant", function( data ) {
function rstListing(data) {
if ($.isEmptyObject(data) === true) {
alert ('JSON return empty');
} else {
for (i=0; i<data.length; i++){
$('#restaurantListing').append('<li id="' + data[i].restaurant_id + '" class="rstList"><img src="http://mydomain.com/file/img/' + data[i].restaurant_logo + '"><h2>' + data[i].name + '</h2><p>' + data[i].city + '</p></li>');
$('#restaurantListing').listview('refresh');
}
}
}
rstListing(data);
}
);
});
//Listview link to Detail Page
$(document).ready(function(){
$('.rstList').click(function() {
var id = $(this).attr("id"); // Get the ID
alert(id);
console.log(id);
});
});
Also tried:
//Listview link to Detail Page
$('#restaurantList').on("pageload", function() {
$('.rstList').click(function() {
var id = $(this).attr("id"); // Get the ID
alert(id);
console.log(id);
});
});
You don't need to make any <li> element to be clickable by your self, when you add the click event to any element, that will be triggered when the item is clicked.
Your problem will basically be that the element is not loaded when the event is bind to it. So you have to add your code inside document ready event like this.
$(document).ready(function(){
$('.liClass').click(function() {
var id= $(this).attr("id"); // Get the ID
};
});
$('.liclick').click(function() {
alert($(this).attr("id"));//Get id of clicked li
localStorage.setItem($(this).attr("id"),$(this).attr("id")); //stored into localStorage
alert("Data from localStorage "+localStorage.getItem($(this).attr("id"))); // get stored id
});
Working Fiddle
You will need to use the event delegation to assign the click event since you are building the HTML DOM dynamically via JSON request, thus not being able to locate the 'li' elements at the time of the page load. So, it would look like:
$(document).on("click", ".rstList", function (event) {
// click event
}
See this link for more details:
jQuery event delegation
I have solved my problem with the example code provided by stackoverflow member here. My previous problem is because I separate the creation of the listview and bind the click listener in two different page event.
After testing the page event sequence, I'm now putting the click listener into the same page event instead of separate to two. Now my code look like this, hope this will help someone bump into the same problem as me:
//Show restaurant listing
$('#restaurantList').on("pagebeforecreate", function() {
alert('pagebeforecreate event triggered');
$.getJSON("http://mydomain.com/api/restaurant", function( data ) {
function rstListing(data) {
if ($.isEmptyObject(data) === true) {
alert ('JSON return empty');
} else {
for (i=0; i<data.length; i++){
$('#restaurantListing').append('<li id="' + data[i].restaurant_id + '" class="rstList"><img src="http://mydomain.com/file/img/' + data[i].restaurant_logo + '"><h2>' + data[i].name + '</h2><p>' + data[i].city + '</p></li>');
$('#restaurantListing').listview('refresh');
}
}
}
rstListing(data);
alert('rstListing() executed');
$('.rstList').click(function() {
alert($(this).attr("id"));//Get id of clicked li
localStorage.setItem($(this).attr("id"),$(this).attr("id")); //stored into localStorage
alert("Data from localStorage "+localStorage.getItem($(this).attr("id"))); // get stored id
});
}
);
});
the app receive a n html dive and create a page and append it to the app
I bind all link-buttons in set of pages to one function
which will do different tasks depends on the id of the page
now I have a problem when a page has more than one link-button
I need the ID of the clicked button
Html:
<a id="x">x </a>
<a id="y">y </a>
Js:
var btns = [];
$('#page-' + newpages[j].pageID + ' a').each(function () {
btns.push({
id: this.id,
value: this.value,
name: this.name
});
});
for (i in btns) {
$('#' + btns[i].id).bind('click', function () {
test(btns[i].id)
});
// bin all buttons in current page to test()
}
};
};
function test(x) {
var page = $('.ui-page-active').attr('id');
/////////
//here I'm trying to ge the ID of clicked button of that page (each ID means something)
var pos = '';
$('#' + page + ' a').click(function () {
//Get the id of this clicked item
var BID = $(this).attr("id");
alert(BID);
send(BID);
});
Why don't you just bind to the click event on each button independently? If you switch by ID anyway why go through a generic function, any shared functionality can be abstracted into a function and utilized by each click handler so you loose nothing.
