I creating jquery Plugin with simple alert option. I did this way see below is my code.But it doesn't work.
Below code is the seperate js file.
(function($) {
$.fn.gettingmessage = function() {
var element = this;
$(element).load(function() {
alertingcontent();
function preventnextpage() {
return false;
}
function alertingcontent() {
alert("nicely done");
});
};
})(jQuery);
I called this function as
this way
$(function(){
$("body").gettingmessage();
});
I am not sure how can i fix this any suggestion would be great.
JSFIDDLE
Thanks
First, you're missing a closing bracket.
Second, the load() function doesn't do what you're searching for, use ready() instead of.
Updated code :
(function($) {
$.fn.gettingmessage = function() {
var element = this;
$(element).ready(function() {
alertingcontent();
function preventnextpage() {
return false;
}
function alertingcontent() {
alert("nicely done");
}
});
};
})(jQuery);
$(function(){
$("body").gettingmessage();
});

I'm getting a 'navigateTo is not defined' error in my JS with the following. I'm pretty sure I have passed the function navigateTo as a parameter to the openCart() function so unsure where I'm going wrong?
$(function() {
var form = $('form#checkout-form'),
$sections = $('[data-step]');
function navigateTo(index) {
$sections.removeClass('is--active').eq(index).addClass('is--active');
}
});
$(document).on('click', 'nav.main a.cart', function(e) {
openCart();
});
function openCart(navigateTo) {
navigateTo(1);
disableScroll = false;
}
your function openCart should go to inside the dom ready function otherwise it doesn't call the function and another thing you need to pass the callback as parameter navigateTo into the opencart function like openCart(navigateTo);
$(function() {
var form = $('form#checkout-form'),
$sections = $('[data-step]');
function navigateTo(index) {
alert(2);
$sections.removeClass('is--active').eq(index).addClass('is--active');
}
$(document).on('click', 'div', function(e) {
openCart(navigateTo);
});
function openCart(navigateTo) {
navigateTo(1);
disableScroll = false;
}
});

It's a scope issue. Wrap your whole script in a closure and you'll be fine;
(function($) {
// your script here
})(jQuery)
But get rid of the $(function() { } around the first block as well.
I'm trying to create a simple plugin that I can call by both: $.myPlugin() and $('something').myPlugin()
Heres the code:
(function($) {
$.fn.myPlugin = function(item) {
return this;
};
$.myPlugin = function(item) {
return $.fn.myPlugin(item);
};
}(jQuery));
This works when called either way mentioned above.
However, calling $.myPlugin().hide() does not work. Any chained methods are failing.
Heres a simple JSBin I made showing the issue
Why?
You should return $(this), not jquery this:
(function($) {
$.fn.myMethod = function() {
this.append('<p>MY METHOD</p>');
return $(this);
};
$.myMethod = function() {
return $.fn.myMethod();
};
}(jQuery));
$(function () {
// Moment of truth
$('.output').myMethod().hide('slow');
$('h1').click(function(){
$('.output').myMethod().hide();
});
});
I want to call a function with a namespace based on its name.
Perhaps some background: What I want is, dynamically bind pages via $.mobile.loadPage(inStrUrl, { showLoadMsg: false }); and then, based on the current page, invoke a function within a loaded page. For example: each page has a showFilter function, the Event is attached to a main.html - page which should call the matching function in the current page.
I also tried some solutions, with jquery too, but nothing works for me.
This is my function code:
function namespace() { }
namespace.showFilter = function () {
alert("Test");
}
And want to "invoke" or "call" it via its name.
This is what i tried at least.
$(document).ready(function() {
var fn = window["namespace.showFilter"];
fn();
});
I get error TypeError: fn is not a function
Here is a fiddle http://jsfiddle.net/xBCes/1/
You can call it in the following way:
$(document).ready(function() {
window["namespace"]["showFilter"]();
});
or
$(document).ready(function() {
window["namespace"].showFilter();
});
or
$(document).ready(function() {
window.namespace.showFilter();
});
I found that I had to manually set it to window.
window.namespace = function() { }
window.namespace.showFilter = function () {
alert("Test");
};
$(document).ready(function() {
var fn = window["namespace"]["showFilter"];
fn();
});
http://jsfiddle.net/xBCes/4/
Like this:
$(function() {
window.namespace.showFilter();
});
P.S. I shortened the $(document).ready(...)
function namespace() {}
namespace.showFilter = function () {
alert("Test");
}
$(document).ready(function() {
var fn = namespace.showFilter();
fn();
});

I just created my first jQuery plugin , it is very simple it slideToggle two Divs , the code works fine and it do what i want , the problem is that i get an ERROR message at the console saying :
Uncaught TypeError: object is not a function
it refer to this line of code
})(jQuery);
CODE
$(function($) {
$.fn.toggleDiv = function(opt) {
var options = $.extend({}, $.fn.toggleDiv.objectOptions, opt);
return this.each(function() {
if (options.animation == true) {
$(this).slideToggle();
} else {
$(this).toggle();
}
});
};
$.fn.toggleDiv.objectOptions = {
animation: false
};
$("button").click(function() { $("#Div1, #Div2")
.toggleDiv({animation : fa}); return false; });
})(jQuery);
Does any one know what is that error and how can i fix it thanks
You either want to do
(function ($) { ... })(jQuery);
if you want your code to be run immediatly,
or
jQuery(function ($) { .... });
for your code to be run on document-ready.
You are referring to $("button"), and therefore need the document tree to be available. So use the second version. A even nicer solution would be to use the jQuery function "delegate", this would look something like this:
jQuery(function ($) {
$(document).delegate("button", "click", function (ev) { ... });
});
I am stuck. Searched and tried for hours.
EDIT:
I still can't make it work. Okay, I'll just put the source code to make it clear what I want to accomplish.
<script src="//ajax.googleapis.com/ajax/libs/jquery/1.5.1/jquery.min.js"></script>
<script type="text/javascript">
var date_fmt="yyyy-mm-dd";
var time_fmt="HH:MM";
var date_field="#id_start_0, #id_end_0"; //id refering to html input type='text'
var time_field="#id_start_1, #id_end_1"; //id refereing to html input type='text'
function clearFmt(fmt_type)
{
if($(this).val() == fmt_type) {
$(this).val("");
}
}
function putFmt(fmt_type)
{
if($(this).val() == "") {
$(this).val(fmt_type);
}
}
$(document).ready(function() {
$(date_field).attr("title",date_fmt);
$(time_field).attr("title",time_fmt);
$(date_field).click(function() {
clearFmt(date_fmt);
});
$(date_field).blur(function(){
putFmt(date_fmt);
});
$(time_field).click(function(){
clearFmt(time_fmt);
});
$(time_field).blur(function(){
putFmt(time_fmt);
});
});
</script>
Help ?
Use the jquery bind method:
function myfunc(param) {
alert(param.data.key);
}
$(document).ready( function() {
$("#foo").bind('click', { key: 'value' }, myfunc);
});
Also see my jsfiddle.
=== UPDATE ===
since jquery 1.4.3 you also can use:
function myfunc(param) {
alert(param.data.key);
}
$(document).ready( function() {
$("#foo").click({ key: 'value' }, myfunc);
});
Also see my second jsfiddle.
=== UPDATE 2 ===
Each function has his own this. After calling clearFmt in this function this is no longer the clicked element. I have two similar solutions:
In your functions add a parameter called e.g. element and replace $(this) with element.
function clearFmt(element, fmt_type) {
if (element.val() == fmt_type) {
element.val("");
}
}
Calling the function you have to add the parameter $(this).
$(date_field).click(function() {
clearFmt($(this), date_fmt);
});
Also see my third jsfiddle.
-=-
An alternative:
function clearFmt(o) {
if ($(o.currentTarget).val() == o.data.fmt_type) {
$(o.currentTarget).val("");
}
}
$(date_field).click({fmt_type: date_fmt}, clearFmt);
Also see my fourth jsfiddle.
The following should work as seen in this live demo:
function myfunc(bar) {
alert(bar);
}
$(function() {
$("#foo").click( function() {
myfunc("value");
});
});
anyFunctionName = (function()
{
function yourFunctionName1()
{
//your code here
}
function yourFunctionName2(parameter1, param2)
{
//your code here
}
return
{
yourFunctionName1:yourFunctionName1,
yourFunctionName2:yourFunctionName2
}
})();
$document.ready(function()
{
anyFunctionName.yourFunctionName1();
anyFunctionName.yourFunctionName2();
});
Note: if you don't use 'anyFuctionName' to declare any function then no need return method. just write your function simply like, yourFunctionName1().
in $document.ready section parameter is not issue. you just put your function name here. if you use 'anyFuctionName' function then you have to follow above format.
function myfunc(e) {
alert(e.data.bar); //this is set to "value"
}
$("#foo").click({bar: "value"}, myfunc);
People are making this complicated, simply call directly as you would in Javascript
myfunc("value");
