I have a table wherein the first column is a checkbox and the second one has a text.
Whenever, the checkbox is checked, I want to know the corresponding value which is in the next cell.
Please tell me how to do.
If I use the getelementsbytagname function, it returns from the start of the document.
This is quite simple to do without jquery. We have a input inside a td so we can go up a level and get the next sibling:
var nextTd = myInput.parentNode.nextSibling;
Because some browser insert empty text nodes between tds we can do the following to make sure we're on the right node:
if (nextTd.tagName != "TD")
nextTd = nextTd.nextSibling;
Also, FWIW, getElementsByTagName can be called from any Node. Thus, if I have a table, I can call
myTable.getElementsByTagName("tr");
To return all rows inside of myTable.
Assuming you're using jQuery (or some other civilized framework), it's pretty easy:
$('table#yourTableId input:checkbox').click(function(ev) {
if (this.checked) {
// not sure what you mean by "want to know" ...
console.log($(this).closest('tr').find('td:nth-child(2)').html());
}
});
You could do it with the jQuery "live" event facility similarly, which'd be cheaper if there are a lot of checkboxes.
The simplest way would be yo use jQuery or a similar library, that implements CSS3 selectors.
$('table input:checked').parent().parent().find('td.nth-child(2)').text():
You could also bind onto the change events of the checkboxes
$('input:checkbox').change = function(){
val = $(this).parent().parent().find('td.nth-child(2)').text():
}

Below is the approach I have used in order to select values from a dropdown using nightwatch.As you can see this is not a good approach. We can't select the specific value from dropdown unless we click on the exact element.
this.useXpath();
this.click('(//td[#class="styles_selectDropdownContainer__2Vrns"])[1]')
this.useCss();
this.click('#react-select-6-option-1')
In selenium java there is a very good option like below
Select fruits = new Select(driver.findElement(By.id("fruits")));
fruits.selectByVisibleText("Banana");
I want to know of there is a similar approach can be used in nightwatch as well?
This is not built up using Select and Option tag so inbuilt selenium functions wouldn't work. Work around would be to click first on the parent span and then in list store every div (which is option), iterate the loop and for each web element if text matches with your desired text you can click on it.
Code :
this.useCss();
this.click("span[aria-live='polite']")
Now store options in a list :
var elements = document.querySelectorAll('.elements'); // use
//div[contains(#class,'option')] as element selector.
Now iterate the list :
// Iterate over them.
[].forEach.call(elements, function (element) {
// Manipulate each element.
element.click();
});
});
I added jQuery to an older application. This is causing some syntax errors so I need to update the older code to be compatible with jQuery. For clarification, once I include jQuery, myTable.rows.length returns "undefined." The reason I am including jQuery is because I want to use DatePicker elsewhere on the page.
Once I changed myTable.rows.length to $('#myTable tr').length; that part worked correctly, which led me to believe I need to update the following snippets as well.
What is the equivalent of the following code, in jQuery?:
myTable.rows[i].cells[0].children[0].value;
If what you are doing works, why change it?
I am not a fan of this, but the same idea would be
$("#myTableId")find("tbody tr").eq(i).find("td").eq(0).children().eq(0).val();
You would probably be better off with having a class on the item you are trying to select.
If it will be the first input in the first cell it would just be
var i = 0;
var rows = $("#myTableId")find("tbody tr");
var inputVal rows.eq(i).find("td :input").val();
It would be
$($("td:first", ($("#myTable tr")[i])).children()[0]).val();
To select the k-th td:
$($($("td", ($("#myTable tr")[i]))[k-1]).children()[0]).val();
Somewhat simpler ( i-th row, j-th cell ):
$("#myTable tr:nth-child("+i+") td:nth-child("+j+")").children()[0].val();
So I try to select a div within another div. My html goes like this:
<div id="Stage_game_page1"><div id="cube0">[...]</div><div id="cube1">[...]</div></div>
I want to select my #cube0 within my Stage_game_page specifically, with jQuery or JS.
The goal of the selection is to use it in an loop.
I tried :
var count =$("#Stage_game_page").children().length;
for(i=0; i<count;i++){
$("#Stage_game_page")$("#cube"+i)[...]
}
I don't understand what I'm doing wrong.
var count =$("#Stage_game_page").children().length;
for(i=0; i<count;i++){
$("#cube"+i);
}
This is sufficient to select the "#cube0"/"#cube1"/"#cube2" etc. especially since ids are always unique. To answer the question $("#cube0", "#Stage_game_page")... that is how you select a div in another div
The id attribute should only be used once! I see above that you're using id="cube0" twice. If you want your divs to be recognized in multiple instances, use a class instead (the . instead of the #). Using the same id twice will probably break your script.
I believe for your html, you could use id "cube0", "cube1", etc., as long as you're ok with entering them manually. That should work for the loop you'd like to use.
Loops through each div that starts with the id cube inside Stage_game_page1
$("#Stage_game_page1 > div[id^='cube']").each(function () {
alert($(this).html());
});
JSFiddle
Child Selctor
Starts with Selector
use each() for loop.
$('#Stage_game_page1').children().each(function(index) {
// your code here with index starts from 0
});
or this using jquery attribute starts with selector
$('#Stage_game_page1').find('[id^="cube"]').each(function(index) {
// your code here
});
You need to use .find() or .children() or the like.
The correct jQuery usage would be
$("#Stage_game_page").find('#cube'+i)
to find a div with that id inside the container #stage_game_page
You have duplicate cube0 in your html code..
and i think the look should contain something like that:
$("#cube"+i)[...]
One another solution is:
$("#Stage_game_page1 div[id='cube0']")
I have table which is being dynamically created.
I would like to try not to have any more attributes in the table (like an ID field).
It is a multilevel table where all the TableRows should be expandable and collapse on click in any of the TD in each row.
$('.fylke_click').click(function () {
$(this).parent().nextUntil('.fylke').slideToggle(0);
$('.sted').hide();
});
$('.kom_click').click(function () {
$(this).parent().nextUntil('.kommune').slideToggle(0);
});
See this simplified fiddle:
http://jsfiddle.net/T2Lwn/
So it's basically 3 levels and it is a lot of problems here.
One obvious one is when you are on the second level, which is called "kommune" and if you click on the last TR it removes the "fylke" underneath. As you can see if you click on "MIDTRE GAULDAL"
This is probably because I use .Parent() and I need some sort of if check if I am on the last row?
Is it also other problems with this code? Can I specify the click method class="fylke_click" and class="kom_click" on a more general level?
For example for all <tr class="fylke"> each TD class will have class="fylke_click" and same for kommunne?
If I understand your issue correctly this may help:
Demo Fiddle:
Since you said you're going to be dynamically creating this content, I would recommend delegating off of the main table instead of making a click handler for each row. Also, since all of the stuff you want to show / hide are siblings and not nested, things get a bit tricky. You'll need to be specific with your .nextUntil() by passing a filter, and I found a :not() on the filter was necessary.
Again, since these are all siblings, it's not as easy as hiding the children of the header row, so I set up an "open" class to check if the header was open or not, and hid / showed stuff depending on if it was already open.
JS:
$('.kommune').hide();
$('.sted').hide();
$('.table').on('click', 'tr', function(){
$this = $(this);
if( $this.hasClass('fylke') ){
if ( $this.hasClass('open') ) {
$this.toggleClass('open').nextUntil('.fylke', 'tr').hide();
}
else {
$this.toggleClass('open').nextUntil('.fylke', 'tr:not(.sted)').toggle();
}
}
else if ( $this.hasClass('kommune') ){
$this.nextUntil('.kommune', 'tr:not(.fylke)').toggle();
}
});
I have a form with which I use jQuery ".clone()" to add new rows. Everything looks great, however I have a binding problem. Basically, on initialization, I use the jQuery ".datepicker()" function for one field (based on class). If I use ".clone()" by itself I don't get any of the ".datepicker()" functionality with the new item. If I use ".clone(true)" I get the functionality, but for cloned rows it fills the date of the row it was cloned from, not the actual row clicked.
I've tried unbinding/rebinding, but none of this works. So, how do I append new rows to a form while still getting all of the jQuery funness to work properly?

EDIT 1 (jQuery):
function addLineItem(){
$('#charges_table tr:last').clone(true).insertAfter('#charges_table tr:last');
}
$(function(){
$('.date_pick').datepicker({"numberOfMonths": 2});
$("#add_line_item").bind('click',function(event){
event.preventDefault();
addLineItem();
$('.date_pick').datepicker('destroy');
$('.date_pick').datepicker();
})
})
FYI, I'm only binding on class, and the HTML elements aren't using an ID to speak of.
When you .clone(), are you changing the ID of the element before you insert it back into the DOM? If not, your ID would be duplicated, and that could be the source of your trouble.
First, as written, your method addLineItem is always going to clone whatever the last row of the table is: $('#charges_table tr:last'). It sounds like you want to clone the table row within which the click occurred. If that is the case, then something like this should do the trick:
function addLineItem(row){
$(row).clone(true).insertAfter('#charges_table tr:last');
}
$(function(){
$('.date_pick').datepicker({"numberOfMonths": 2});
$("#add_line_item").bind('click',function(event){
event.preventDefault();
// Pass the closest 'tr' element to the element clicked.
addLineItem($(this).closest('tr'));
});
});
I haven't tested this code, but it is based on similar table row cloning code in one of my projects.
