I asked this question by gitHub, but I try it here as well maybe someone knows the issue.
I am using slim select plugin, when I try to select the second option after searching I get an error
see picture:
But when I click outside so that the drop down goes closed and start searching again then I can select many options without getting the error.
Here is the code snippet where slimselect is initialized:
function initDropDowns () {
$('[slimselect]').each(function (index) {
var id = $(this).attr("id");
var placeholder = $(this).data("placeholder");
var selectByGroup = true;
var compareDropDown = false;
var dataSelectByGroup = $(this).data("selectbygroup");
var dataCmpareDropdown = $(this).data("comparedropdown");
if (dataSelectByGroup) {
selectByGroup = dataSelectByGroup === "true";
}
if (dataCmpareDropdown) {
compareDropDown = dataCmpareDropdown === "true";
}
var that = this;
var select = new SlimSelect({
select: '#' + id,
placeholder: placeholder,
showSearch: true,
searchText: settings.texts.noSearchResults,
searchPlaceholder: settings.texts.searchPlaceholder,
searchingText: settings.texts.searchingText,
searchHighlight: true,
closeOnSelect: false,
showOptionTooltips: true,
selectByGroup: selectByGroup,
hideSelectedOption:true,
limit: 5,
beforeOnChange: function (info) {
if ($(that).data('singleselect') === true) {
dropDowns[that.id].set ([]);
}
},
onChange: slimSelectOnChange
});
dropDowns[id] = select;
});
}
Im using django-el-pagination to do lazy loading of entries.
When I click on an entry and then use the browser back button, all of the lazy loading is gone, I tried to add window.history.pushState() but then I only get the current page i.e.?page=4 when I use the browser back button, and all of the entries on top is not loaded.
Is there any way to implement a correct history so that the user is back at the same place when they use the browser back button?

$.endlessPaginate = function(options) {

})(jQuery);
short answer: no. The whole point of 'endless pagination' is to not reload a (new) page, therefore there is no history.
Here is the essencial part of my custom code. I believe the onchange function is in confict with the function with the 3rd party plugin im using which also targets the same "option" tag.
jQuery(document).ready(function(e) {
var t = e("#filter-container");
t.imagesLoaded(function() {
t.isotope({
itemSelector: "figure",
filter: "*",
resizable: false,
animationEngine: "jquery"
})
});
$("select").on("change", function() {
var select = $(this);
var selectedOption = select.find("option:selected");
var r = selectedOption.attr("data-filter");
t.isotope({
filter: r
});
return false
});
e(window).resize(function() {
var n = e(window).width();
t.isotope("reLayout")
}).trigger("resize")
})
and here the probable culprit from the dropdown plugin im using. It is much longer than that but here the function that worries me which probably blocks my script:
$("select").on("change", function() {
var select = $(this);
var selectedOption = select.find("option:selected");
var n = select.parents(".filter-buttons");
var r = selectedOption.attr("data-filter");
t.isotope({
filter: r
});
return false
});
both function are part of seperate scripts so I cant join them together. Is there any way to make the second function not cancel the first one out?

I tried to use your fiddle, but it didn't seem to work.
Try adding a unique namespace to your change event.
$("select").on("change.optionChange", function() {
var select = $(this);
var selectedOption = select.find("option:selected");
var r = selectedOption.attr("data-filter");
t.isotope({
filter: r
});
return false
});
I have a function set up with the jQuery cookie plugin: https://github.com/carhartl/jquery-cookie, with the click function on .grid-block it stores each data-hook in an array, saves them as a cookie, then these chosen divs are viewable on the /itin/your-itin/ page. Here's a demo I've set up too: http://nealfletcher.co.uk/itin/ If you click on the .grid-block divs, this will add them to your itinerary, then when you navigate to: http://nealfletcher.co.uk/itin/your-itin/ only these divs are viewable and stored as a cookie for x amount of time. This works great, BUT if I then go back to add more divs, these are stored as a cookie, but the previous ones are wiped, I want to keep appending to the array, store it as a cookie, then when you navigate to: http://nealfletcher.co.uk/itin/your-itin/ it will display all your selections, even if they've been added separately. If that makes sense?
jQuery:
$(window).load(function () {
var cfilter = [];
var $container = $('.block-wrap');
$container.imagesLoaded(function () {
$container.isotope({
itemSelector: '.grid-block',
animationEngine: 'best-available',
filter: '.grid-block',
masonry: {
columnWidth: 151
}
});
$(".grid-block").click(function () {
var thing = $(this).attr("data-hook");
var test = "." + thing;
cfilter.push(test);
$.removeCookie('listfilter', {
path: '/itin/your-itin/'
});
// We need to set the cookie only once
// it stays at the url for 7 days
$.cookie("listfilter", cfilter, {
expires: 365,
path: '/itin/your-itin/'
});
});
if ($.cookie("listfilter") !== 'null') {
// console log just for testing
console.log($.cookie());
$('.block-wrap').isotope({
filter: $.cookie("listfilter")
});
return false;
} else {
// !! this part could be refactored
// as you don't really need to check against the url
// when the cookie doesn't exist show all elements
$('.block-wrap').isotope({
filter: ''
});
}
});
});
Any suggestions would be greatly appreciated!
Change var cfilter = []; to var cfilter = $.cookie("listfilter");
This way you load the changed cookie and add to it instead of overwriting it.
Better code practice would be to check if the cookie exists before using it though, but you get my hint.
You made an error in implementing my change:
if ($.cookie("listfilter") !== 'null') {
var cfilter = [];
} else {
var cfilter = $.cookie("listfilter");
}
is wrong, use
if ($.cookie("listfilter")) {
var cfilter = $.cookie("listfilter");
} else {
var cfilter =[];
}
Looking off this example, notice how clicking on the Search button brings up a modal form with a darkened overlay behind it. Now notice how clicking on the Column Chooser button brings up a modal form but no overlay behind it.
My question is: how do I get the dark overlay to appear behind my Column Chooser popup?
There are currently undocumented option of the columnChooser:
$(this).jqGrid('columnChooser', {modal: true});
The demo demonstrate this. One can set default parameters for the columnChooser with respect of $.jgrid.col too:
$.extend(true, $.jgrid.col, {
modal: true
});
Recently I posted the suggestion to extend a little functionality of the columnChooser, but only a part of the changes are current code of the jqGrid. Nevertheless in the new version will be possible to set much more jQuery UI Dialog options with respect of new dialog_opts option. For example the usage of the following will be possible
$(this).jqGrid('columnChooser', {
dialog_opts: {
modal: true,
minWidth: 470,
show: 'blind',
hide: 'explode'
}
});
To use full features which I suggested you can just overwrite the standard implementation of columnChooser. One can do this by including the following code
$.jgrid.extend({
columnChooser : function(opts) {
var self = this;
if($("#colchooser_"+$.jgrid.jqID(self[0].p.id)).length ) { return; }
var selector = $('<div id="colchooser_'+self[0].p.id+'" style="position:relative;overflow:hidden"><div><select multiple="multiple"></select></div></div>');
var select = $('select', selector);
function insert(perm,i,v) {
if(i>=0){
var a = perm.slice();
var b = a.splice(i,Math.max(perm.length-i,i));
if(i>perm.length) { i = perm.length; }
a[i] = v;
return a.concat(b);
}
}
opts = $.extend({
"width" : 420,
"height" : 240,
"classname" : null,
"done" : function(perm) { if (perm) { self.jqGrid("remapColumns", perm, true); } },

});
In the case you can continue to use the original minimized version of jquery.jqGrid.min.js and the code which use can be just $(this).jqGrid('columnChooser');. Together with all default settings it will be like
$.extend(true, $.ui.multiselect, {
locale: {
addAll: 'Make all visible',
removeAll: 'Hidde All',
itemsCount: 'Avlialble Columns'
}
});
$.extend(true, $.jgrid.col, {
width: 450,
modal: true,
msel_opts: {dividerLocation: 0.5},
dialog_opts: {
minWidth: 470,
show: 'blind',
hide: 'explode'
}
});
$grid.jqGrid('navButtonAdd', '#pager', {
caption: "",
buttonicon: "ui-icon-calculator",
title: "Choose columns",
onClickButton: function () {
$(this).jqGrid('columnChooser');
}
});
The demo demonstrate the approach. The main advantage of the changes - the really resizable Column Chooser:
UPDATED: Free jqGrid fork of jqGrid, which I develop starting with the end of 2014, contains of cause the modified code of columnChooser.
I get the following error while trying the code on the mobile device.
Result of expression 'selector.data('dialog').uiDialog' [undefined] is not an object.
The error points to the following line of code.
selector.data('dialog').uiDialog.resizable("option", "alsoResize", resizeSel + ',' + resizeSel +'>div' + ',' + resizeSel + '>div>div.ui-multiselect');
When I inspect the code, I find that the data object does not have anything called uiDialog.
just been looking thru the code, try adding this line:
jqModal : true,
to this code:
$grid.jqGrid('navButtonAdd', '#pager', {
caption: "",
buttonicon: "ui-icon-calculator",
title: "Choose columns",
onClickButton: function () {
....
like this:
$grid.jqGrid('navButtonAdd', '#pager', {
caption: "",
buttonicon: "ui-icon-calculator",
title: "Choose columns",
jqModal : true,
onClickButton: function () {
....
