I want to set the id of the tr that is the result of the tag liferay-ui:search-container-row, how can I do it?
For Example, the resulting table row is:
<tr id="aui_3_4_0_1_350" class="portlet-section-header results-header">
I want to attach some javascript for the resulting table and I need something to refer to the various table row, like id="aui_3_4_0_1_350".
I could also use the class selector, but I don't know how to set it.
It is not posible to set a customized id value to a search-container-row. Because they get generated based on the input list and Ids need to be unique. However you can access it using a selector starting with the search-container itself. It depends on what you are trying to accomplish.
If you're using jQuery or similar it should be easy since there's a good variety of them: https://api.jquery.com/category/selectors/
If you want to give an element an id you should do it with setAttribute
For example, you first need to get a reference to the element that you want to give the id, with:
var id = document.querySelector("p").setAttribute("id", "idName");
if this is what you're looking for.

I have a long list of <li>, each which has a data-val attribute. Example:
<li data-val="yesterdayTrip">Trip</li>
Using jQuery attribute^=value I can locate a particular <li> based on a partial string match and using css can alter the <li>. Such as:
$("[data-val^='yes']").css("background-color", "yellow");
But I don't want to turn the background yellow, I want to get the full data-val value. The following does not work, although it seems to me that it should:
var fullValue = $("[data-val^='yes']").getAttribute("data-val");
How can I get the value for data-val?
to get the data-val attribute you can use
$("[data-val^='yes']").data("val")
or
$("[data-val^='yes']").attr('data-val')
either one will get the value. However, if you have multiple selectors match, then it will only get the first one, you'll have to put it in a loop to get all of them.
To get the attribute data of type data, you should only call the data method that provides jquery, example :
$("[data-val^='yes']").data('val');
or
$("[data-val^='yes']").attr('data-val');
I have one textbox .the id is account_0__abc.the id will dynamically generted one.my question is how to select the id ending with __abc textboxes in a whole form using jquery?
Try to use attribute ends with selector,
$('[id$="__abc"]')
There are various selectors in jQuery to identify elements based on a part of their id or names. You can specify the element type as well.
Here's an example:
$('input[id$="__abc"]')
This will grab <input> elements with id ending with __abc. Be careful though, if you got multiple ones that match this criteria, you'll end up with a collection. You can iterate through the collection and do stuff to them with a .each() like so:
$('input[id$="__abc"]').each(function(){
// magic
});
If you want to make it more specific such as start with account_ and end with __abc then you can use:
$('[id^="account_"][id$="__abc"]')

I have a repeater and have a label with an icon inside it.
<strong><i id="iconProperties" class="icon-caret-right"></i> Properties</strong>
When i click a button the icon-caret-right must be turned to icon-caret-down. i have written the code as follows:
$('#iconProperties').removeClass('icon-caret-right').addClass('icon-caret-down');
When i use this code only the first row of the repeater is working. all other rows's icons are not changing. What is the mistake?
ASP.net generates unique ids for html elements and only one element can have id iconProperties that you used in selector. You can use Attribute Contains Selector [name*="value"] instead of id selector to get all the matching elements.
$('[id*=iconProperties]').removeClass('icon-caret-right').addClass('icon-caret-down');
If your ids have a similar name, you're probably after something like
$('[id^=iconProperties]').removeClass('icon-caret-right').addClass('icon-caret-down');
Which will update all items beginning with id "iconProperties".
It might be worth noting that it is common practice to use unique ids.
Try this:
$('#iconProperties').find('.icon-caret-right').replaceWith('.icon-caret-down');
I just wanted a fast/easy/simple way to check for existing ID on a specific element (div in this case)..
Can't seem to find code sample for this..im using jquery but i dont think i need to do jquery on this one, just basic getElement.. but i need to isolate the search inside a div block.. because the id does exist in other elements on the page but i need to know if it exist in a specific area/div.
so instead of just
document.getElementById(target_id);
i need something like:
divName.getElementById(target_id);
or
$("document.divName").getElementById(target_id);
or
$(".divName").document.getElementById(target_id);
Can't seem to find something that works.
IDs are supposed to be unique and no two elements in page should have same id. You may search some element with some class in div with specific ID.
$('#divId .someClass')
or using find()
$('#divId').find('.someClass')
or using context, jQuery( selector [, context ] )
$('.someClass', $('#divId'))
var mySubDiv = myParentDiv.querySelector("#mySubDivId")
is equivalent to
var mySubDiv = document.querySelector("#myParentDivId #mySubDivId");
// don't forget the space : #myParentDiv#mySubDivId won't work
where querySelector and querySelectorAll are very useful functions, enough for me to avoid using jQuery : they accept any css selector
in real life, using the same Id for different DOM elements often happens.
id's should be unique, you can check for element using:
$(".your_parent_div").find("div#some_unique_id");
you can use it for the getElementsByTagName or ClassName, but ID is unique over document. so doesn't need to do that. better to use a special ID.
and in every id define as a element in javascript and you can just write id's name and use it, like this :
ID.style.color = red;
According to my understanding on your question, You have used two id's with same name when u execute, It takes only first ID so you are asking to take id from the specific div, well that is bad type of coding to use two id for same name instead go for class if want to use same name.
solution for your question is -this ->
var someDiv = document.getElementsByClassName("divName");
var someId = someDiv[0].getElementById("target_id");
I am really new to JavaScript, and Im basically trying to build a simple Script to get information from a site like Walmart.com. Im using firebug to test my little snippets. Im having a problem getting the price.
This is the my code:
var price = document.getElementById('clearfix camelPrice');
console.log(price);
I also tried ".camelPrice" with out the period and I keep getting null.
Thanks a lot in advance!
In this case, you're using the wrong method. getElementById does exactly what it says, it gets an element by its id. Looking on Walmart.com, 'camelPrice' is a CSS class.
We can still get elements by a class. What you want is document.getElementsByClassName(). Further, you can pass multiple arguments to getElementsByClassName like so:
document.getElementsByClassName('clearfix', 'camelPrice');
This grabs all elements that have both the clearfix and camelPrice classes set.
In addition to what the others have said about your selection looking like ids, here is how you can select by class name:
document.getElementsByClassName('classname');
Newer browsers allow you to make jQuery-like selections from native JavaScript:
document.querySelectorAll('#id .classname');
http://caniuse.com/queryselector
It looks like you're trying to provide a class selector to getElementById instead of an ID selector. This is what an ID looks like:
<div id="some-id">...</div>
This is what a class looks like:
<div class="some-class">...</div>
The difference is that only one element should ever have a specific ID on a page, where many elements might have the same class.
I am not sure how you are running your JavaScript in Walmart's site, which is not impossible, but maybe you should specify it, for instance if the Walmart site is in an iframe you will not be able to use getElementById() from your site.
On the other hand if you are running some sort of local Live Editor/Console, then maybe it is possible.
For the script you show above, you have an error on the ID since an id can only be one word, and you are missing to select what type of attribute you want from the element:
For example, <input>:
var price = document.getElementById('id').value
or for other tags like <div>:
var price = document.getElementById('id').innerHTML
