I get form from zend framework site and put it in response in new file in function written by jquery mobile, but I get this error:
uncaught exception: cannot call methods on selectmenu prior to
initialization; attempted to call method 'refresh' .
Code of function this file:
function addItem(id) {
$.ajax({
url:'http://zf.darina.php.nixsolutions.com/order/index/create-order-mobile',
dataType:"jsonp",
data:{id_good:id},
success:function (resp) {
console.log(resp);
$('.product-table').empty();
$('.product-table').append(resp.prod);
$('.product-table').append(resp.form);
$('.add-order-btn').button();
$('.mob-size').selectmenu('refresh', true);
$('#block').page();
}
})
}
Force initialize the selectmenu(s) first:
$('.mob-size').selectmenu(); // Initializes
$('.mob-size').selectmenu('refresh', true);
or use this for short
$('.mob-size').selectmenu().selectmenu('refresh', true);
In my case, if I was not initializing the select before invoking the 'disable' method I got the error, while if I was initializing it, the select didn't disable but duplicate itself - I tried to select the object by TAG NAME instead of by CLASS or ID NAME,
$('select').selectmenu('disable');
instead of
$('.select-class-name').selectmenu('disable');
and it worked without forced initialization
you do this in your custom refresh delegation function:
var w = $("#yourinput");
if( w.data("mobile-selectmenu") === undefined) {
// not initialized yet, lets do so
w.selectmenu();
}
w.selectmenu("refresh",true);
according to enhancement resolution here
I found the same problem, but a more involved solution. When jqm wraps the select element, it puts it in a <span> element with the same class list as the select element. I changed my reference to it so that instead of reading:
row.find(".selectCompletion").selectmenu("disable");
it now reads:
row.find("select.selectCompletion").selectmenu("disable");
Specifying that jquery should only find the select element matching the class name, rather than all elements in .row that match the class name, solved the problem.
This happened to me when cloning existing select element in order to duplicate the original section multiple times.
Calling 'refresh' for the original element, worked fine, while calling it for the cloned sections was leading to the error appearing in the question.
However, calling selectmenu() was causing a 'vandalisation' to the form, as can be seen in the following image:
Explanation: top = original. bottom = vandalised cloned element right after calling selectmenu.
Solution:
The following code solved this vandalisation problem:
cloned_elem.find('select[name=MyClass]').selectmenu().selectmenu("destroy").selectmenu();
This is not an ideal solution because we must call the first selectmenu() in order to call selectmenu("destroy"), so I would be glad to hear of a cleaner solution.

I've added some custom elements to be included with my WooCommerce account page to be seen with the order history. Unfortunately the page is setup with tabs to only display the information pertaining to the active tab.
I'm not very familiar with jquery, but I thought it would be simple enough to use Jquery to hide the divs I added when the order history has a display of none.
I added the following script to my theme's main.js file:
$(document).ready(function(){
var display = $('.my_account_orders');
if(display.css("display") == "none") {
$('.paging-nav').css("display","none");
}
});
When the class .my_account_orders has a display of none it should change the div I added (.paging-nav) to have a display of none. But it just doesn't work.
Is there something wrong with this script or do I need to do something special to initiate it? Since it's in my theme's main.js file and I used $(document).ready(function() I figured it would just load with the page.
Any help with this would be greatly appreciated.
Instead of using:
var display = $('.my_account_orders');
Implement it into the if statement like this:
if($('.my_account_orders').css("display") == "none") {
Because originally it is trying to find a variable called $display, so it would return a syntax error of undefined.
You've got an errant $ in your if statement. This should work instead:
$(document).ready(function(){
var display = $('.my_account_orders');
if(display.css("display") == "none") {
$('.paging-nav').css("display","none");
}
});
Also keep in mind that your var display is only going to match the first element that has a class of my_account_orders, so if there are multiple elements with that class, and they don't all have the same display, you could get unexpected results.
Try this:
$(document).ready(function(){
var display = $('.my_account_orders');
if(display.css("display") == "none") {
$('.paging-nav').css("display","none");
}
});
I believe it's a very lame way to check for a css property such as display to determine if an element is hidden or not. With jquery, you can make use of :hidden selector which determines whether an element is hidden and return a bool value.
$(document).ready(function(){
if($('.my_account_orders').eq(0).is(":hidden")) // eq(0) is optional - it basically targets the 1st occurring element with class 'my_account_orders'
{
$('.paging-nav').css("display","none");
}
});

I am trying to find out if my click is on a specific Highcharts chart. I cannot use the click event on the chart, since the area is in the title, not on the chart itself, and Highcharts does not support click events on anything beyond the plotted area.
$(document).mouseup(function(event) {
var clickedElement = event.target;
if (clickedElement == "chart_1")
console.log('yes');
console.log(clickedElement);
});
I save the event.target in a variable; then I would like to check if what I clicked is a specific chart (I have multiple charts on the same page, each one in its div).
This is what I get as output of console.log; when I click on a Highchart:
<rect x="0" y="0" width="880" height="150" strokeWidth="0" rx="15" ry="15" fill="url(#highcharts-2)" class=" highcharts-background"></rect>
I would like to check the fill and see which chart am I clicking on, to then trigger an event.
I tried to use a search by string, but it fails since the object returned from event.target is a DOM (from what I understand, I am just starting with this); so how can I access the values in the variable, and compare them, so I can look for a specific value for the class or for the fill?
EDIT:
Thanks Adeneo!
The solution that works is the one using .getAttribute. This will return "yes", when I click on a chart that has in the fill "url(#highcharts-2)"
$(document).mouseup(function(event) {
var clickedElement = event.target;
if (clickedElement.getAttribute('fill') == "url(#highcharts-2)")
console.log('yes');
});
All the others didn't work when I tried them, the comparison would always fail; this is the only one that works. Thanks again
You can use getAttribute
clickedElement.getAttribute('fill')
just wrap it in jQuery and use prop() to get property:
$(clickedElement).prop("fill")
If you're using jquery version < jQuery 1.6, use
$(clickedElement).attr("fill")
Other wise for jQuery versions > jQuery 1.6 use
$(clickedElement).prop("fill")
How do I hide a single tab on a MVC/Kendo UI tabstrip?
I want to hide a tab based on a condition. My jQuery code goes like this:
//authUser is a hidden input whose value is set in the controller and passed into the view
if ($('#authUser').val() == 'False') //hide the last tab
{
$($("#tabstrip").data("kendoTabStrip").items()[6]).attr("style", "display:none");
}
When I run the code I get the following error on the line of code that's executed if authUser is False:
JavaScript runtime error: Unable to get property 'items' of undefined or null reference
Ideas?
The fact that 'items' is undefined implies that you never appropriately selected the tabstrip in the first place. Either your CSS selector is wrong (are you sure you named it tabstrip?) or you did not follow the Kendo method names appropriately.
Here are two ways I found to hide the last tab:
Hiding the last tabstrip element
var tabStrip = $("#tabstrip").kendoTabStrip().data("kendoTabStrip");
//Find the last tab item's index from the items list
var lastIndex = tabStrip.items().length - 1;
//Use jQuery's hide method on the element
$(tabStrip.items()[lastIndex]).hide();
Using Kendo's tabstrip remove method
I believe the following is more appropriate. Why not use the tabstrip's remove method and completely remove it from the DOM since the user should not have access anyway?
var tabStrip = $("#tabstrip").kendoTabStrip().data("kendoTabStrip");
tabStrip.remove("li:last");
I'm just stupid....
I looked some more at the code and I was leaving out the kendoTabStrip() word (bolded) from
$($("#tabstrip").kendoTabstrip().data("kendoTabStrip").items()[6]).attr("style","display:none")
i.e. Instead of (properly) having:
$($("#tabstrip").kendoTabStrip().data("kendoTabStrip").items()[6]).attr("style","display:none")
I had:
$($("#tabstrip").data("kendoTabStrip").items()[6]).attr("style","display:none")
Drew, thanks for your effort. Sometimes I just have to beat my head on a wall until I see what I've done.
So here's my problem: I'm using a function and I need the function to be specific to each tr with the class "middleone". It's supposed to change the insides of a div inside of the the tr with the class "middleone". But it's not working!
I know the recursive portion of it is working, and the "navigation" should be spot on, because even when i'm using just $(this) it doesn't do anything. When using document.getElementById it works fine but of course that only targets the first div and the full version of the code has to "Go here, pull from here, put it here, go to the next area, pull from here.. etc" Here's the testing code.
$('.middleone').each(function() {
var tripleeagain = $(this).find('div')
tripleeagain.innerHTML = "$";
});
Thanks for any help
tripleeagain is a jquery object collection upon which you should use html() instead of innerHTML
Basically you could just write:
$('.middleone').find('div').html("$");
If you are doing specific stuff inside the loop then:
$('.middleone').each(function() {
//Some specific logic
var tripleeagain = $(this).find('div').html("$");
});
The problem is you are trying to access native API from a jQuery object.
var tripleeagain = $(this).find('div');// this will return a jQuery object
So you should use the jQuery API for setting the html contents
tripleeagain.html("$");

$("[littleBox]").load("ajax.php?eid="+$(this).attr("littlebox"));
the $(this).attr("little box") portion of the code returns undefined.
I'm trying to get the individual attribute of the initial $("[littleBox]").
this particular line of code is called as the soon as the document is ready.
when I put predefined values, such as
$("[littleBox]").load("ajax.php?eid=1");
It works as expected. Unfortunately, I need it to load specific content based on that element's attribute. Any idea how to make this work?
Loop through all items with proper this:
$("[littleBox]").each(function() {
var $this = $(this)
$this.load("ajax.php?eid="+ $this.attr("littlebox"));
});
this will not refer to $("[littleBox]") in that context, you'll have to repeat the selector - or select the element already and re-use it:
var $box = $("[littleBox]");
$box.load("ajax.php?eid=" + $box.attr("littlebox"));
post yout html that cotnain attr "little box" in it.
is it like
<a attr="little box" id="test">test<a/>
then it work like
$('#test').click(function(){
alert($(this).attr('little box'));
});
