I want to have a button with js click in each datatable row, but my code is broken by datatables paging system - default datatable option. Click works only on first datatable page. My only idea is to disable paging and create scrolable datatable, but I would prefer to keep paging for better UX.
Example datatable:
<table id="data_tables">
<thead>
<tr>
<td>Action</td>
<td>Name</td>
<td>Surname</td>
<tr>
</thead>
<tbody>
<!-- Datarow 1 -->
<tr>
<td><input type='button' class='my_button' data-id='1' value='click' /></td>
<td>John</td>
<td>Wayne</td>
</tr>
<!-- Datarow 2 -->
<tr>
<td><input type='button' class='my_button' data-id='2' value='click' /></td>
<td>Clark</td>
<td>Kent</td>
</tr>
</tbody>
</table>
Click event handler
//simple on() in jquery would do the trick in normal <table>
$( ".my_button" ).on( "click", function() {
var id = $(this).attr("data-id");
alert(id);
});
Is there a way to workaround this problem? Or maybe datatable api solution?
You can do something like this:
$("#data_tables").on("click", ".my_button", function() {
var id = $(this).data("id");
alert(id);
});

I'm using material desigin lite in my website
I have implemented this example:
http://www.getmdl.io/components/index.html#tables-section
<table class="mdl-data-table mdl-js-data-table mdl-data-table--selectable mdl-shadow--2dp">
<thead>
<tr>
<th class="mdl-data-table__cell--non-numeric">Material</th>
<th>Quantity</th>
<th>Unit price</th>
</tr>
</thead>
<tbody>
<tr>
<td class="mdl-data-table__cell--non-numeric">Acrylic (Transparent)</td>
<td>25</td>
<td>$2.90</td>
</tr>
<tr>
<td class="mdl-data-table__cell--non-numeric">Plywood (Birch)</td>
<td>50</td>
<td>$1.25</td>
</tr>
<tr>
<td class="mdl-data-table__cell--non-numeric">Laminate (Gold on Blue)</td>
<td>10</td>
<td>$2.35</td>
</tr>
</tbody>
</table>
my question is how to handle the check box in the table , they are added by the class : .mdl-data-table--selectable
there is no Id or class for them so what is the way to use them in javascript or sql server (deleting rows what i'm trying to implement)
You could check if they're are clicked with a jquery on method, why am not using the normal .click is to because of event delegation. Jquery docs do a perfect job explaining that.
Before I explain how I did it I will have a snippet that you can immediately play with under my explanation.
I basically used inspect element to look at the tables structure and it looked something like this
<tr>
<td>
<label>clickable checkbox code</label>
</td>
<td>Acrylic</td>
<td>25</td>
<td>$2.90</td>
With that information, we can do a lot. I personally used this to listen to clicks.
$(document).on("click",".mdl-checkbox__ripple-container.mdl-js-ripple-effect.mdl-ripple--center", function() { /* Code here*/ });
And with jquery parents & children methods we can achieve a lot, like read the content of all the table data with the following code in our click event listener
foo = $(this).parents().eq(2).children().text();
Or we can perhaps delete a whole row?
$(this).parents().eq(2).fadeOut();
What that would do is, look at the clicked checkbox using "this" as reference. Then go to levels up and remove a whole row.
<tr><!-- eq 2 -->
<td> <!-- eq 1 -->
<label>clickable checkbox code</label>
</td>
<td>Acrylic</td>
<td>25</td>
<td>$2.90</td>
Or we can check for the content of a specific child like this
var secondChildContent = $(this).parents().eq(2).children().eq(2).text();
Where secondChildContent will be return the content. You can always change the eq (The one after children) value to the desired child number you want. In the following case secondChildContent would return "Acrylic"
<tr>
<td> <!-- eq 1 -->
<label>clickable checkbox code</label>
</td>
<td>Acrylic</td> <!-- eq 2 -->
<td>25</td> <!-- eq 3 -->
<td>$2.90</td> <!-- eq 4 -->
$(document).ready(function() {
$(document).on("click", ".mdl-checkbox__ripple-container.mdl-js-ripple-effect.mdl-ripple--center", function() {
//Removing row
$(this).parents().eq(2).delay(500).fadeOut(300);
var secondChildContent = $(this).parents().eq(2/*child number*/).children().eq(2).text();
var allChildrenContent = $(this).parents().eq(2).children().text();
var parentID = $(this).parents().eq(2).attr('id');
//Removing table on click of first checkbox
if (parentID == "header") {
$("#mdlTable").fadeOut(1000);
$("#log").html("<b>Table removed!</b>");
} else {
//Don't pay attention to this
$("#log").html(
"<b>Second child content is: </b>" + secondChildContent +
"<br><b>All children content is: </b>" + allChildrenContent
)
}
});
});
#log,
#mdlTable {
margin: 1% 1% 1% 1%;
}

When a checkbox is selected, the tr gets the class "is-checked" with Material Design Lite.
So your jquery can be like this:
$("table").find("tr.is-checked").each(function(){
// Do some stuff!
});
Update: Just read that the class "mdl-data-table--selectable " is being deprecated... This is the article on github
You can use this OnClick API function.
It uses like Android onClickListener, but it is for JavaScript.
TablesOnClickListener = function() {
var fun;
this.setOnClickListener = function(listener) {
fun = listener;
$(document).on("click", ".mdl-checkbox__ripple-container.mdl-js-ripple-effect.mdl-ripple--center", function() {
//$(this).parents().eq(2).delay(500).fadeOut(300);
var secondChildContent = $(this).parents().eq(2 /*child number*/ ).children().eq(2).text();
var allChildrenContent = $(this).parents().eq(2).children().text();
var parentID = $(this).parents().eq(2).attr('id');
fun({
sen: secondChildContent,
text: allChildrenContent,
id: parentID
});
});
}
How to use:
Step 1: create new TablesOnClickListener
var tocl = new TablesOnClickListener()
Step 2: set Item OnClickListener
tocl.setOnClickListener(function(data){
console.log(data);
});
Now your Tables Item Listener are all set!
I have a table with 4 columns . 4th column is a button (not shown in below code). When I click on the button in a row, I want to get row elements.
I have done it using closest selector. Is there any way to find table row element "Without using closest". This is the requirement for some reason.
Please assume there is a button at end of each row
<table id="food">
<thead>
<tr>
<th>Number</th>
<th>Name</th>
<th>Type</th>
</tr>
</thead>
<tbody>
<tr class='details'>
<td>1</td>
<td>Apple</td>
<td>Fruit</td>
</tr>
<tr class='details'>
<td>2</td>
<td>Mango</td>
<td>Fruit</td>
</tr>
<tr class='details'>
<td>3</td>
<td>Grape</td>
<td>Fruit</td>
</tr>
</tbody>
</table>
Here is the existing code, I need to replace closest. It will be awesome if I can use class names like $(this).somethin('.details');
$('#button1').click(function(){
var row = $(this).closest('tr');
//Do some stuff
})
Thanks
Use parents() and pass a class selector like
$('#button1').click(function(){
var row = $(this).parents('.details');
//Do some stuff
})
Note, you could also use closest in this case and pass the class selector
var row = $(this).closest('.details');
I want to design a customize table layout. For example after adding data my table is created. Now I am showing column name in one column and column data in another column, I want to add functionality if I drag one row to third column, Then column structure will be modified and that row will be added to new column.
For example: This is my table: jsfiddle.net/x8L57md2/
code:-
<tr>
<td>Name</td>
<td> Ankur </td>
</tr>
<tr>
<td>Address</td>
<td>jaipur</td>
</tr>
<tr>
<td>State</td>
<td> Rajasthan</td>
</tr>
<tr>
<td>Country</td>
<td>India</td>
</tr>
<table>
If I move state column to right side of ankur(name) then another table column will be created and append it to table with data.
Like this: jsfiddle.net/ttzr2ezh/
code:-
<table border="1">
<tr>
<td>Name</td>
<td> Ankur </td>
<td>State</td>
<td> Rajasthan</td>
</tr>
<tr>
<td>Address</td>
<td>jaipur</td>
</tr>
<tr>
<td>Country</td>
<td>India</td>
</tr>
<table>
Dragging tr elements is a little tricky. Here's a modified version of a clever approach from a different post. You can view a fully working JSFiddle here: http://jsfiddle.net/xwyoe0y9/
// make sure you reference jQuery and jQuery UI
$(document).ready(function() {
var dragInfo = {};
$('table.rearrangeable tr').draggable({
helper: 'clone',
start: function(event, ui) {
dragInfo.tr = this;
dragInfo.helper = ui.helper;
}
});
$('table.rearrangeable tr').droppable({
drop: function(event, ui) {
var tr = ui.draggable;
$(this).append(dragInfo.tr.innerHTML);
$(dragInfo.tr).remove();
$(dragInfo.helper).remove();
}
});
});
Look up jQuery UI, there is simple functionality for making a UI item 'sortable'.
With this new library installed you just need to label the rows or individual elements and in Javascript make them 'sortable'.
HTML:
<table>
<tr class='makeSortable'>
<td>Element1-Title</td>
<td>Element1</td>
</tr>
<tr class='makeSortable'>
<td>Element2-Title</td>
<td>Element2</td>
</tr>
<tr class='makeSortable'>
<td>Element3-Title</td>
<td>Element3</td>
</tr>
</table>
Javascript:
$(function() {
$( ".makeSortable" ).sortable();
$( ".makeSortable" ).disableSelection();
});
I have a table like this:
<table>
<tr>
<td>foo</td>
<td><button>delete</delete></td>
</tr>
<tr>
<td>foo</td>
<td><button>delete</delete></td>
</tr>
</table>
I want to use JQuery to install a click handler on the delete buttons such that it deletes the current row when clicked
Give a class of, for example, "delete" to the delete buttons, then use this:
$("button.delete").click(function() {
$(this).closest("tr").remove();
});
Alternatively, if you can't add the class, you can use the :contains selector:
$("button:contains('delete')").click(function() {
$(this).closest("tr").remove();
});
Update (now that the code in the question has completely changed)
Now that you have changed the code in the question to contain only one button instead of two, you don't need to bother adding the class, or using the :contains selector, you can just use the plain old button selector:
$("button").click(function() {
$(this).closest("tr").remove();
});
Try this. As a side not you should not have same id to any dom element on the page.
$("button").click(function() {
$(this).closest("tr").remove();
});
In your markup the tags are not closed properly. E.g the button tag is not closed properly so the selector will not work. Give a unique id or a class name to select the required buttons.
Something like this
<tr>
<td>foo</td>
<td>Some content</td>
<td><input type="button" class="delete" value="Delete" /></td>
</tr>
Using delegate to attach event handler only to table for better performance. This way the click event will be attached only to the table element no matter how many rows it has.
$("table").delegate("input.delete", "click", function() {
$(this).closest("tr").remove();
});
You can try soemthing like this:
<table>
<tr>
<td>row 1, cell 1</td>
<td><img class="delete" src="del.gif" /></td>
</tr>
<tr>
<td>row 2, cell 1</td>
<td><img class="delete" src="del.gif" /></td>
</tr>
</table>
And your jQuery:
$('table td img.delete').click(function(){
$(this).parent().parent().remove();
});
First off, there's a syntax error in your HTML, and you should a class identifier for easier access to those buttons:
<table>
<tr>
<td>foo</td>
<td><button class="delete">delete</button></td>
</tr>
<tr>
<td>foo</td>
<td><button class="delete">delete</button></td>
</tr>
</table>
Next, here's the jQuery code you need:
$(function() {
$('button.delete').click(function(event) {
event.preventDefault();
$(this).closest('tr').remove();
});
});
What is the best method in jQuery to change a particular table row into a form ?
For example to change :
<table>
<tr><td>edit</td><td>first row</td></tr>
<tr><td>edit</td><td>some row</td></tr>
<tr><td>edit</td><td>last row</td></tr>
</table>
into :
<table>
<tr><td>edit</td><td>first row</td></tr>
<tr>
<form>
<td>edit</td>
<td><input type='text' name='a' value='b'/></td>
</form>
</tr>
<tr><td>edit</td><td>last row</td></tr>
</table>
Update : the html we finally use :
<form>
<table>
<tr>
<td><img class="editRow"></td>
<td class="field">field to know</td>
</tr>
</table>
</form>
and the jQuery code :
$( ".editRow" ).click( function() {
var rowToEdit = $(this).parent().parent();
var field = rowToEdit.children(".field")
rowToEdit = .replaceWith( "<td></td>\
<td>\
<input type='hidden' value='"+field+"'>\
</td>"
});
Try out the function .wrap(). For more infomation see here.
There is a jquery function that does exactly what you are revering to, basically it allows you to create a table and then each cell is editable so you don't have to use just google it a bit. You will find it
