I have 1 form, and dozens of elements. In the select elements I use onchange="somefunc()". In this function I'd like to access and change the form element attributes (such as form.element.option[].value and form.element.option[].innerHTML).
Is there a way to access the element that has just changed (unsing onchange="somefunc()") by passing a "this.element" parameter to access the elements properties such as form.element.option[].value within the function?
I am dynamically building a part of my HTML page by setting the innerHTML of a DIV element. Immediately after I do that I try to retrieve the clientHeight and clientWidth of the DIV element in order to determine what height and width the element actually ended up being. But I always get 0 as both the height and width. The contents of the DIV, i.e. the HTML code that I inserted into it via the innerHTML, does indeed get displayed on the page. But I suspect that the browser doesn't actually update the page until AFTER my JavaScript code has completed and "returns control" to the browser.
Does that make sense? Is there any way I can force the browser to update the page BEFORE my code completes its processing, so that I can properly retrieve the width and height of the element I just inserted into the page?
I have an object on the document element that allows for other components to register with it, i have a custom event something along$(document).bind("register",function(thechild)..So in the child object when they are created i call$(document).trigger("register",this);And indeed i get the DOM object. However i'm looking for the plug in object, i want to be able to call methods on the passed childobject and access it's Config.Does that make sense? How can i write a plug in that is applied to various objects that also registers itself with an 'overseer' object on the document element in such a way that i can allow that overseer object to call methods on any registered child objects?
i am creating text box Elements using DOM if only user needs it by using Create Element
var element = document.createElement("input"); element.setAttribute("type", "Textbox"); element.setAttribute("name", "group[]"); newdiv.appendChild(element);
Assuming the name of my form was "form", I could access the value of the text fields by "window.document.form.FIELDNAME.value" and the select by "window.document.form.public.selectedIndex". But the page i'm working with has multiple products listed and so I've addopted a nming convention for the elements name's so that I could access it more efficiently in PHP. So for example, I'd have multiple products as such Code:
I am fairly familiar with the concept of Objects and their properties and methods, but javascript being object based as opposed to object oriented has me stumped on how to access an object's properties from an onclick event handler created for another object created within the original object.In the example below, I have a constructor function called anyObj. to which I pass an object reference to an element.
anyObj has 3 properties and one function increaseWidth()
increaseWidth() creates a new button with an onclick event handler and this is where I have a problem.The onclick function needs to increase the value of anyObj's this.width property. I originally had a line this.width += 10; in the onclick but quickly realised why this wasn't working because the this in the onclick function refers to the new button object and not the this.width property of anyObj.
The workaround I have used, and it works, is to make a copy of all the this.xxxxx properties. eg. width = this.width; and use the width variable in the onclick as you can see below. This "workaround" works fine but doesn't feel ideal to me.So, what I am asking advice on is, is there a better way to access the anyObj()'s properties from within the onclick function than the way I have done it? Obviously I would prefer to not have to make copies of all the anyObj() properties like I have to make them accessible to the onclick function.
Code:
function anyObj(divObj){ this.elem = divObj; this.width = 50;
I am working on a little javascript project, and I need to get an arbitrary element's style information.
For instance, I want a method that you can pass a reference to an object, and for instance, find the current css height property that applies to it, no matter where it was declared. I don't mind it returning a null value if it wasn't set anywhere, but if it's coming from some css class or some css id or some locally defined style, I want to know what is being expressed.
If I just try el.style.height, it only lets you know what the height is if it was explicitly defined in the style tag.
I have a billion elements that all share the same class. I have another billion elements that all share another class. This cannot be changed. My objective is to use one element to trigger onclick a change in the others elements' css properties, that is each element is paired with another, producing a billion unique pairs. From hours of deciphering the cryptic documentation examples ive come up with the following, which doesnt work. Assume that im using "name=item#" in the element's tag to identify each pair.
One fundamental issue with this is that it will change the opacity of both elements in the pair were both elements to share a name,or it will only affect the element being clicked on if not, but i only want it to change the opacity of the element that isnt being clicked. Another issue is that there are instances where i may need to set a setTimeout on a css property, and ive not found any documentation on integrating javascript and jquery together within a function.So how do i get this function to accept input from one element and affect the css properties of the other? And what would a setTimeout look like if it were placed around the opacity property?
How do I restore CSS properties for a selected element? I want to change the background-color of a particular item on click, then restore the original CSS bgcolor from the stylesheet when it's clicked a 2nd time.
The item in question has a CSS class applied to it from the stylesheet.
On a page I display a link of search results which are hyperlinks, which all have the same URL get paramaters with different values (i.e. companyreport.aspx?....). I want to then click on a search result hyperlink and then generate a Div popup (this is called through a javascript call that is attached to each search result hyperlink's onClick property.
For the hyperlink that is clicked, I need to take its 'href' value and use it (reason for us is in a bit).
On the popped up Div element is a dropdown box and two buttons (accept / decline). Once the accept button is pressed, I want to then go to the page the selected hyperlink was pointing to by using the 'href' value I obtain from the clicked search hyperlink and to also append to this hyperlink the a new GET parameter and the value of the dropdown box.
I have got this to work currently but it seems quite mess, so was wondering if there is a better solution to this.
I'm trying to append an onChange attribute to an element created through javascript. The following doesn't work. The select is created and has the proper name and id but no onChange..
var sel = document.createElement('select'); sel.name = 'size[' + i + ']'; sel.id = 'size[' + i + ']'; sel.onchange = "changeMini();";
I have a small HTML form that has a textfeild which when clicked on open a calender, this works fine. I also want to display the selected date in another textfeild using "OnChange". This is what I am working with:
In a project repeated blocks are identified by an <input type="hidden" value="x" /> field. To get an access to one of the block I wanted first access to that field. My first problem is there and I will explain it by a micro-project (tested with Firefox only)
Here is the HTML code : <!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "[URL]"> <html><head> <meta http-equiv="Content-Type" content="text/html; charset=utf8" /> <meta http-equiv="Content-Style-Type" content="text/css" /> <meta http-equiv="Content-Script-Type" content="text/javascript" /> <link rel="stylesheet" href = "index.css" type="text/css" /> <script type="text/javascript" src='Library/jquery-1.4.js'></script> <script type="text/javascript" src='index.js'></script> .....
And here the javascript code wher is the JQuery question //meta http-equiv content-type charset=utf8 function test(){ var $id = $('#curUnion').val(); var $objet = $('#toutesUnions > .pseudoFieldset').find('input[value=$id]'); var $test = $objet.val(); var $objet2 = $('#toutesUnions > .pseudoFieldset').find('input[value="1"]'); .....
With $id = "1" as shown by the Javascript debugger (in Firefox) where is the difference between find('input[value=$id]') and find('input[value="1"]') Giving the alert result => undefined / 1 If you want to test the micro project you will find it in the Test.zip joined. How to access the immediate parent pseudoFieldset to get its html code?
I am trying to access an element in a page using ID using jquery in when the document is ready.But the problem is the length is always 0 even if the script tag is in the head or right at the bottom of the page. The element is seen rendered when I see it using FireBug.an someone point out where I am making a mistake accessing the element
I have been scratching my head on this one for a couple days:
Code: function hideAll(){ var education = document.getElementById("education").childNodes;
[Code]....
As far as I know, this should be working the way I expect it to (set the display of all the childnodes to none), but I guess I'm missing something. Is it not possible to instantiate a variable using childNodes without choosing a specific index of the array? I just assumed it would work like any other array
and i want to access the element dropSubPrd that is inserted on that ajax function, on the div FirstResult, but it will not work in $('document').ready because when the page load's that element isnt there.
When retrieving JSON data I'm able to access individual elements using the $.each() function and iterate over them. However, how would I access just one element by its location and not by name? (i.e. data(0) not data.ID).
<script type="text/javascript"> function insertPreference() { var row = document.getElementById('voteTable').rows[0];[code]....
I can get the value for id and title. However, I can not get the radio button value.I will loop through the <tr> tag and access the <td> and pass it to AJAX module in (id + title + value) manner.Is there a way to do that?
