I am new to jQuery so please go easy, I have a form that will represent an Advanced Search. Users will be able to add rows to refine their specific search.
Each row has 3 elements: A Checkbox & 2 x Select boxes.
As can be seen in the fiddle I am using jquery to clone the row and place the cloned row after the last row.
Everything is working fine except visually I would like the checkbox to use Bootstrap-Switch http://www.bootstrap-switch.org/
And the select boxes to use Selectize https://github.com/brianreavis/selectize.js
Now, when I clone the row with these plugins not active, everything works.
I have NO idea how to re-render or re activate them once a new row is inserted.
Is this something that is plugin specific? Or kind of universal to jquery?
I have read HEAPS of answers on here about similar things but I cannot seem to get it right.
Here is the jquery snippet:
$adSearchForm = $('#adSearchForm');
$adSearchForm.on('click', 'button, input, select, option', function (event) {
console.log("Button Clicked", event)
});
$('#addSearchRow').click(function(event){
$('[data-content=adSearch-3]:first').clone().insertAfter('[data-content=adSearch-3]:last');
// $('.searchByField,.searchOperator').selectize({refreshItems: true});
// $('[data-toggle=switch]').bootstrapSwitch({refreshItems: true});
});
Here is the fiddle, hope its ok. http://jsfiddle.net/CkVQr/6/
Thankyou very much for your help.

Plugins change your HTML
There are two major problems you may not be fully aware of with your code:
Whenever you do a .clone() it merely deep clones your DOM element subtree, but not any event handlers bound to cloned elements.
Your .selectize() plugin changes HTML of your form quite considerably, converting input elements to other things. So whenever you clone your already converted select filter row, and subsequently want to run .selectize() on it again, this particular plugin won't find any suitable input elements to convert. Hence it won't work. Everything will just look as it should but won't work.
What can be done?
The main idea is that whenever you clone your search filter row, you have to clone your original HTML and not after it was converted using your plugins.
HTML Templates to the rescue
One of the possibilities is to change you page (and functionality) a bit and put your search filter row in a template and always use that. When you create your first row, you should read the template (and cache it) and add+convert it on your page. When you'd add an additional row, just use the same cached template and add+convert it again.
HTML template
<script id="filterRow" type="text/x-template">
<!-- Your filter rown HTML goes in here -->
</script>
Some Javascript
var cachedTemplate = cachedTemplate || $("#filterRow").html();
...
$('#addSearchRow').click(function(evt) {
var newRow = cachedTemplate.clone(); // clone for reusability
newRow.insertAfter('[data-content=adSearch-3]:last');
newRow.selectize();
...
});

tableDnD (table Drag and Drop) is a jQuery plugin I'm using to be able to re-order rows in my html table. It's a pretty cool library, but the fact that you can click, drag, and drop rows -- disables the ability to select that row by clicking -- it thinks you might be starting a drag and drop, or doing a 0-distance drag.
So you can view my example here, and see what I'm talking about -- http://jsfiddle.net/du31ufts/5/
It starts off as disabled, so enable the row re-ordering and see the library. Then, try to select just one row in the middle. The only way the blue highlighting indicating selection shows up is if you click outside the bounds of the table, and thus you would only be able to select starting from the bottom or top, and not be able to select one row at a time. I need to select these rows to be able to copy-paste these rows into excel.
I've tried looking into the library itself and detaching $('__dragtable_disable_text_selection__'), I've tried jquerys removeAttr for unselectable, I've tried
$('.dragtable-sortable').attr('-moz-user-select', 'none');
Nothing is re-enabling my ability to be able to click and select single rows. I'd like to do this without modifying tableDnD functions.
Which CSS properties could be affecting my ability to select table rows?
Create a textarea somewhere with ID #spot.
Use this code to extract data on click from a row and select it. Its delimited by tab so it should be pastable into excel easily.
$('tr').click(function(){
var copyContent = "";
$(this).children('td').each(function(){
copyContent = copyContent+$(this).text()+"\t";
});
$('#spot').val(copyContent);
$('#spot').select();
});
I asked about this on github and got an answer: It did require modification of the library. Specifically, replacing the if block starting at line 207 of the fiddle in this question with this
if (!$(this).hasClass("nodrag")) {
if (e.target.tagName == "TD") {
$.tableDnD.initialiseDrag(this, table, this, e, config);
return false;
}
}
modified fiddle. Thank you tschqr
I"m working on an asp.NET project. My code-behind page binds to a repeater control that fills a table on the page.
I've hidden the table with CSS while it's empty. I'd like to use jQuery to make the table visible when the repeater fills it, but I'm having trouble making that work. Here's a bare-bones example:
$('#MyTable').change(function () {
$('#MyTable').show();
})
I'm using a plain HTML table, not an asp:Table, so I don't need to use the .ClientID workaround and I can't manipulate it on the server side. I've also tried putting the .change event on the repeater control, but that doesn't work either. The table stays hidden after the new rows are added.
Can anyone suggest a way, hopefully straightforward, do do what I'm trying to do?
The change event fires for combobox, listbox when selected index fired, i dont't think it will fire when you append tr to tables.
However, you can have work around for this, take a asp:panel or simply a div that will contain your html table, and you can set this panel visibility to true when you append rows in your html table.
If you use plain HTML table, change will not work, try this solution:
HTML table onChange
you can use the livequery plugin which will detect the DOM change.
first add the livequery plugin to the page and then try this
$('#MyTable tr')
.livequery(function(event) {
$('#MyTable').show();
return false;
});
hope this helps.
In Typeahead JS I'm trying to add an option that appears at the bottom of the dropdown after the user has started typing. Currently I'm using the 'onOpened' Custom Event to trigger adding some HTML after the 'tt-dropdown-menu' element is initialised.
.on('typeahead:opened', onOpened)
function onOpened($e) {
$('.tt-dropdown-menu').html( "Add Option" );
}
The problem is that the jQuery HTML is added when the dropdown is initialised, as expected, then when the user starts typing the new dataset element with the autocomplete results in is added below that jQuery HTML so the jQuery HTML can never appear at the bottom of the dropdown. You can't append the jQuery HTML to the dataset either as that element doesn't exist when the dropdown is initialised.
Is there an easier way around this? The other Custom Events don't seem to cover this scenario.
If you only have one dataset, you can do as I do: add a footer to the dataset, and add it as a DOM element, not plain HTML string. You can then change it at will (say on any event you wish) and your changes are reflected in the dropdown.
Example:
$('#myinput').typeahead({
// rest of your regular stuff, like 'name', 'remote', etc.
footer: $('#dropdown-footer'),
});
... where dropdown-footer is the ID of a div you have somewhere in your dom. You can then do things like:
$('#dropdown-footer').html('Hello')
I'm building a simple asp page on which I have list of peoples with checkbox on left of every name.
I've managed to create a simple jQuery script that allows hiding and showing rows of table based on input:
http://jsfiddle.net/Tq97v/ (first part)
As You can see I can enter part of name and then specific row are hidden.
Using red "x" I can uncheck all checkboxes.
What I'm trying to do now is to change that static red "x" into tristate checkbox.
Don't have idea how to even start.
Do I must add change listener to every checkbox in my list?
Second thing - how to create multiple instances of the same "plugin" on site.
Right now I'm identifying input by it, but it would be nice to call function with that input as param, and it would fine table after that input and create necessary logic.
This way I could call function multiple times on page to have more than one list.
I'm not asking for whole solution (of course it is always welcome :) ) but what I need is idea how to accomplish this in efficient way and as optimized as possible, because sometimes my list has 500+ elements.
P.S. don't look at HTML code, it is ASP generated.
I found this plugin: https://github.com/bcollins/jquery.tristate, but I have no idea how to use it with my list.
UPDATE:
I've managed to turn my code into functions, but right now I must call 3 functions for every list.
Here is my updated code: http://jsfiddle.net/65MEV/4/
How can I change it to one function? Will it be better?
This is my updated code. Still thinking about way of doing that Indeterminate Checkbox instead of my remove image.
UPDATE2
I build working code :)
http://jsfiddle.net/65MEV/9/
But I would like to improve it as much as possible.
Any suggestions are welcome!
A tristate checkbox is like the Three-Portal Device: an illusion.
What you actually want is to make the checkbox indeterminate (by setting the property of the same name to true). To implement this, you will need a change (or click) handler on each checkbox, then you'll need to check if all of them are in the same state, and if not then you set the indeterminate property. It's a hassle, really, because you rarely see indeterminate checkboxes and so most users don't know what to do with them. To be avoided, if possible.
To create multiple instances of the same plugin access elements relatively to an other element.
For example: in your case instead of keeping the item in a jQuery object var $tableRows = $('table.myList tr'); access them in the event.
$('#user_name').keyup(function () {
var sValue = $.trim($('input#user_name').val());
if(lastInput==sValue) return;
var $tableRows = $(this).next().next().find("table.myList tr");
if (sValue == '') {
$tableRows.show();
} else {
$tableRows.each(function () {
var oLabel = $(this).find('label');
if (oLabel.length > 0) {
if (oLabel.text().toLowerCase().indexOf(sValue.toLowerCase()) >= 0) {
$(this).show();
} else {
$(this).hide();
}
}
});
lastInput=sValue;
}
});
and you only have your actual list.
And for the tree state checkbox you don t need a plugin just add a button or link and every click check it status you can keep the status by jQuery data and change the element image according to this data.
Im looking for a way to render an html table as an editable datgrid, with the ability to clone individual rows. I dont need to save any of the changes made, just superficially edit the cells because i then use a jquery plugin to scrape the table as is on screen and save it.
Ive tried jeditable, but its designed for posting the output of its edits to a page, not just superficially making the changes.
Ideally, i could control what types of inputs are displayed onclick based on what column they are on. The table cells are unnamed. If they need to be named, there are a total of 34 columns, so i would need to know how to name those individually.
Thanks in advance.
Jeditable's target can be a function (see the "Submitting to function instead of URL" section of the jeditable homepage) - you could pass an empty handler and use it.
[Edit]
The handler should return a string (that will be displayed on the page)
(taken from the example page)
$('#test').editable(function(value, settings) {
return(value);
}, {
type : 'textarea',
submit : 'OK',
});
It work nicely, I just tried it out.
