I'm new at JS.
I need to remove TR elements from parent table but the problem is there are no table ID/Name
Is it possible to perform it?
Please see attach - i need remove red marked block... what scrip i have to use if i will put it to the green block?
if you have a form with pre-checked radio or checkbox elements it is not possible to remove the checked states neither with
$('#id').attr('checked', false);
//or
$('#id').attr('checked', '');
nor with
$('#id').removeAttr('checked');
If the elements are not pre-checked but you check them with mouse click - it works as expected. Background: I have a search form which is prefilled based on previous selections and queries but I need a reset button to clear all checkboxes and fields.
This time I have a trouble with remove(). Here is my code :
$.each(val.produitsIds,
function (j, val2) {
if($('#chk_' + i).prop("checked")){
//$('#' + val2).prepend("<div>liste des tailles</div>");
$('#' + val2).prepend("<div>" + $('#chk_' + i).attr("value") + "</div>");
}

I want to remove a specific box when i click on the remove button in that box. I have a lot of boxes on a page but when i click on the remove btn it removes all the boxes. I just want to remove the box where i click on the delete btn.
This is the js code:
$(".del").click(function() {
$('div.floating-box').remove();
});

I'm currently reading jQuery - Novice to Ninja (fantastic book), and trying to understand how I can add several words to the code snippet below. I currently remove, let's say Sweden as below, but what if I also want to remove Norway?And another question, what if I would like to keep only Sweden and remove the rest from a list of twenty countries? How would I do that?
Code JavaScript:
jQuery(document).ready(function() {
jQuery('#countries tbody').remove(':contains("Sweden")');

I'm using a jquery plugin called jplayer. I need to "bookmark" the current track.
The only way to know the current file playing is to look at the div called jplayer_playlist_current.
<li class="jplayer_playlist_current">
<a href="#" id="jplayer_playlist_item_1" class="jplayer_playlist_current">Introduction and guidance on usage</a></li>
What I want to get from it is the id, ie: jplayer_playlist_item_1
I thought that this might cover it:

But nothing I do, no amount of googling or plugins, is getting me this result.
I want to move a div around a page, and I do this by getting the original top and left values of a div, and then change them. But the problem is getting the original values; I checked online and thought that this would work:
var chart = document.getElementById(charDiv).style.top;
var charl = document.getElementById(charDiv).style.left;
alert('char_t:' + chart + ' char_l:' + charl + 'charDiv:' + charDiv);
charDiv is passed into the function (its the id of the div I want to move). I know that charDiv has a value by looking at the values of the alert() statement, but the values of chart and charl are empty. The alert simply outputs char_t: char_l: charDiv: charOne
I attempting to set attributes for all tags of a particular type....
I have a bunch of thumbnails <img> tags; when I wand over them I would like to show the corresponding large image with a script but the tags require onMouseOver events. I really don't feel like adding a bunch of onMouseOver="myShowScript" attributes to every img tag manually...
my scripts aren't working. I'm sure there is some fundamental concept about java and html I don't get...
here's ONE of the versions that doesn't work.. I've tried a few things but I'm open to scrapping everything for a better way...
function addAtts(){
var numberOf = document.getElementsByTagName("img");
for(i = 0; i < numberOf.length; i++){
numberOf[i].onMouseOver="myShowScript()";
}
}
I have this js function for pulling out a couple of links which I want to add onclick handlers to... but IE can't find the rel attribute the way Im doing it, Im assuming it can another way, but I dont know how?!this works in Chrome, but not IE... the category_links.length yields a fat 0.
function get_product_categories_links(){
var links = document.getElementsByTagName('a');
var category_links = [];

I have an application where a user can create a newsletter with a
contenteditable div box and submit it to a database. The problem occurs
when the user tries to edit their newsletter. The edit page looks
exactly like the create page only their already created newsletter is
supposed to appear in the contenteditable div box. To do this I
retrieve the information from the database in the server side. Then I
have the following client side script.
window.onload=doInit
function doInit() {
var content = "<%=sContent%>";
div.innerHTML = content;
}
This seems to work in all cases except if the HTML to be displayed
contains any style attributes. For example, if any of the text has
background color then the HTML code will have the tag <font
style="bacground-color: #000000"> and this will cause nothing to appear
in the div box. Has anyone run into this problem or know how to fix it?
I have a web form with several "submit" buttons.
One of these uploads a file, and I want to validate the user input
prior to submitting the form. I have an event handler specified with
the form's "onsubmit" attribute which checks the the
event.target.value to make sure the right submission type is being
evaluated.
When I try to get the target or srcElement value from the event
object, however, it is always "undefined".
Here is the cut-down version of the handler...
function validateIfUpload() {
if (window.event) {
evt = window.event
} else if (document.event) {
evt = document.event
}
if (evt.target) targ = evt.target
else if (evt.srcElement) targ = evt.srcElement
if (targ.nodeType == 3) // defeat Safari bug
targ = targ.parentNode
if (targ.value == "Upload") {
return validateUpload('prod_img_f')
}
return true
}
I'm having an issue with CSS, JS and the DOM. It's gonna drive me batty. I
am trying to access the properties of a layer in JS which have been
initially set in an external CSS. The problem is that for some reason JS
isn't receiving NULL for all the properties of the layer. For instance:
HTML
<div id="blarg">.....</div>
JS
var t = document.getElementById("blarg").style.left;
CSS
#blarg{
position: absolute;
left: 200px;
}
t == NULL and I can't figure out why. It is this way for any CSS attribute
I attempt to read (width, positional, the whole kit and caboodle).
It does work if I set the attribute in JS before I read it.
JS
document.getElementById("blarg").style.left = 30;
var t = document.getElementById("blarg").style.left;
t now == 30. The only thing I can think of to explain this is that when
the document gets loaded my layers aren't getting their attributes filled
out. The object gets created and the attribute fields are blank until I
fill them in. Thusly my creation of CSS's was a waste of time. Grr...
Any ideas/suggestions? Google has been of no help. :-( This is occurring in
IE 6, and the gecko engine browsers.
While trying out some of the code given in the book, I found that passing CSS properties and values in the jQuery is not working somehow. Following is what I have written.
$(document).ready(function() {
$('#first tbody tr:even').css('background-color': '#dddddd',
'color': '#666666',
'font-size': '11pt',
'line-height': '2.5em');
});
Where as if Ipass CSS properties infollowing way, it is working. But I would need to write multiple statements for that. $('#first tbody tr:even').css('color', '#873450');
If I have the following hyperlink :
<p><a href='page.htm' id='foo' class='bar' alt='alt text'>click</a></p>
I know that I can get (eg) the href attribute via $('a').attr('href') BUT I would like to do the following :
get *all* the attribute names and values without knowing anything about the attribute names and values in advance (or even how many there are) - something like a loop and $('a').(attribute name, attribute value). I suppose they would best be placed in a JavaScript object as a set of name/value pairs eg { href: 'page.htm', id: 'foo', alt: 'alt text' }
it has been a short time since i use jquery. I am now stuck on a problem with jquery- getting a xml node's all attributes as an array for example.. I have searched a lot on that with no luck Is there a way on getting all attributes of a node with jquery?

I need to be able to get the css attributes that a particular class defines. Such that if I have a class called "SomeClass" I want to see if it defines the attribute "position". I've tried using .css on an element that has the class, but of course that picks up the defaults and any inheritance.

I'm adding and removing SVG images in and out of a Parent SVG and I need to implement a scroll like effect on the new images after they are imported. They consist of text that I've word wrapped on the server. The images are imported through xmlrpc calls "getURL" with a function to delete the previous info and add the new info. After which it has a set of group tags with the new svg embeded between them. My hope is there is a way to manipulate the viewBox attributes but I don't know how to extract the 4 attributes of viewBox as separated integer values. I thought svgDocument.getElementById('detail').getAttribute('viewBox') would do it for me but I get a string of characters. Does anyone know how to get all four attributes as separated numerical values?
View 1 Replies View RelatedI need to change dynamically how a class is displayed, my site (with out going into detail) interprets saved info from the user (its saved through perl) in a *.js file, then views it through template *.htm files drawing on js files after loading.
The thing is I need to allow for several settings like font type size and color, (things that could be held in style sheets) but then save in their js file a number representing this and load it when the template page is opened.
I have two possibilities to answer this
1, instead of using classes I could use Ids - but using 1 id for what could (hypothetically) be an endless string of elements seems real messy, I don't even know if it would work.
2, I read somewhere I could dynamically generate style tags with the classes defined, but I can't find where I read this..
I'm creating an img element and appending it where needed. Is it better to set the new img element attributes like this:
var imgEl = document.createElement('img');
imgEl.src = "images/cal.jpg";
imgEl.width = "16";
[code]...
or should I be using imgEl.setAttribute('src', 'images/cal.jpg');
Is there anyway using Javascript, one can determine whether or not the browser viewing the page supports a particular CSS property or value? For example, I know IE6 doesn't support the value of "fixed" for the "position" property, so is there anyway I can determine this with Javascript, without resorting to browser sniffing?

Overlay is called as an onmouseover event from an image's map AREA tag, sending event and a number. FF's JS Console spits out that fdot has no properties. Ideas? Better ways to do this effect (replace the image depending on which area of the imagemap is mousover'd)?
