Now, when I click on the header row, I would like to hide a column, and when I click on an image, I'd like to restore it. Ideally, I would have a function like such:
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?
// simplified to remove all the try/catches & stuff function newXHR() { request = new XMLHttpRequest(); XMLHttpRequest.prototype.requested = null; return request; }
then later:
function doRequest(url, callback) { var req = newXHR(); req.requested = url;
// et cetera.... }
This works fine in Firefox, however the line 'req.requested = url' causes an error in IE7, (I haven't tested IE6 yet). The error is 'Object doesn't support this property or method'
So, this leads me to believe that either a) XMLHttpRequest.requested is not writable, or, b) XMLHttpRequest.requested was never created in the first place. I think it's the first option because I'm not getting an error in the newXHR() function.
I've been searching for some documentation on this but I can't seem to find anywhere if properties created with the prototype keyword are writeable in IE. Does anyone know what the problem is?
I am currently working on a tween script that I am hoping to make so it allows the user to choose and object than the property it tweens, whether it be height or opacity.so currently my problem is getting the function to accept dynamic property selction.for example, the following.
Code: function tween(object,property,to,time){ original = object+property;
how to add extra properties to html elements as I was storing data in html attributes. After looking at some others code including Raphael and this addEvent code. [URL] They seem to treat objects just like an array. obj[property] = value; This would have been extremely helpful to know previously as I have needed to be able to include variables in property names - but have resorted to making the whole thing a string and calling exec() on it.
I have a div called pageWrap to wrap my page with the css as margin-top:-46px;
I would like to use Javascript onClick on another div. This Div is called loginButton, the onclick should change the the css of pageWrap to 0px and onclick again should change it back.
<script language="JavaScript"> var bgImage = new Array(); // don't change this bgImage[0] = "images/aboutus_1.jpg";
[code]....
this goes on, however, it does not change the background when clicking on "Welcome" or "About us" Links. Where I want "About us" to load image#0 in the index and "Welcome" to load image #1.
I'm using a simple script that moves a DIV from one location to another when the user mouses over it. The problem is, I want the user to have to click the div for it to move and then click it agin to move it back. I've been trying to find a simple solution without luck. Code:
I've set up a few images to change onlick using the following code (I have the alternate images saved as jpgs in the img/ directory). There are two problems I'm having the first baffles me, after clicking one image and changing it the other images take 2 clicks before changing. The other problem is more of a curiosity, I plan to have these images work as a sort of check box for a sql database query and I'm not entirely sure my current way of doing it will allow for that.
Code: <body> <head> <script language="JavaScript" type="text/JavaScript"> var q=0;
I am trying to create a button that when pressed changes not only the value of the button but the onclick event. I basically need the function to toggle between these two functions but I can't get it to work. The button changes value but will not update with the new onclick value.
I am building a site where I want all links to partial page reload using xmlhttprequest and innerhtml. I have done this before, butI always had to have a seperate xmlhttprequest function for each link. So this time I am trying to write just one function, and have the onClick change which document the request is getting. It is not working and I appear to novice to figure out why. Here is the code, i have bolded some relevant lines:
<script type="text/javascript"> function ChangeContent() { var whichPHP;
[Code]....
Also, if I use the innerhtml function to write another of these hrefs, will that link be able to access the function if it is in the header, or should I put the entire function in a .js file on the server? The point of all this would be that the entire page never reloads and all the text content is swapped out on demand.
The following is a very simple example of what I want to do take an elements oncontextmenu and changing it dynamically onclick of that same element. The code below will fail unless you change the line
I hope that someone can help me with this strange problem I have here. I have some script which changes a button and changes the onclick event. The strange thing is that although it is changing it. All the events have the same parameter even though my code is giving each button's onclick event it's own unique parameter.
I have an image set to the background, this method is working for fire fox, here is how i got a background image.
<img src="docs/Plasma.gif" id="background"/> <div id="content"> Right after the body tag and img#background { position:fixed; top:0;
[Code]...
When someone clicks on these thumbnails it changes the backround image's source to the bigger version. It doesn't work in IE though and i am confused why. I have tried preloading the image, but I feel as though my Javascript is being ignored.
I would like to change the value of a single hidden input onclick. The possible values are text, email and URL.I've tried all kinds of "ways" (inline and in function in a variety of ways,) but nothing. I stripped it down one last time to give it another go, but realize I'm out of ideas, so the code below is simply where I've thrown in the towel.Can someone make this work with a JS function, so that each link may be clicked and change the hidden input's value to the respective value?
when the image is clicked with the mouse, function func1 is invoked as expected. When I call function changeFunction, I want to change the code that is invoked when the image is clicked from func1 to func2. Instead, both are invoked because addEventListener and attachEvent add an additional handler instead of setting one.
I am looking for a way to change the handler from one function to another. Can anyone think of a solution probably using removeEventListener?
I have a button that needs to increase/decrease the value of a text field when clicked. This code is working in Internet Explorer and Chrome, but not Firefox.
I am trying to stop a preloaded images used in a rollover. The images are linked to a tab navigation system, that open on the same page.
if(document.images){ var image_array = new Array(); // path to the directory with images var path = './images/food-drink/food/'; // enumeration of the "active" images
I have a textbox thats initial text color is set to grey, I want to change the text color to black when the user clicks on it, is this done by using onclick="style=color:Black;" I have tried this and failed but maybe ive got something slightly wrong or is it done a different way completely.
My problem is i do not know the syntax for changing the button image when on click meaning when i click on a imagefield button it will change to another imagefield button and when i click again it will change back.I know that we have to create a function something like this?I am not sure of the syntax but will learn from you expertX - what to put in here?
I have this partially achieved when clicked, any number will indeed "turn into" an h1'd representation of itself but I can't get the other links in the group to disappear when the h1'd number appears (onclick).
I'm working on an ordering form which calculates the total order price using Javascript. I have a checkbox which I want to use to toggle the display of various items, and also reset the value of an item depending on whether or not it is checked.
Further details
I have a checkbox for the colour "Black" which, when checked, hides a SELECT, a bit of text, and "Quantity" field. It also resets the value of the "Quantity" field to zero.
When the "Black" checkbox is unchecked, the three items (SELECT, text and Quantity) are revealed again, and the Quantity field for "Black" is reset to zero and hidden.
The reason is that users can only either EITHER a black item or select from a list of colours. Black items are a different price to all others.
How the form works
When the user enters a quantity into a text field for each item, the price of that item is added to the total at the bottom of the form. When the form is submitted (with PHP validation), it emails the order to a salesperson. The price of each item (for emailing the order) is set using hidden form fields with defined values, while the order total is calculated using the id of each quantity field (e.g. "item_31_85.00").
What I need to know
I want to achieve the following when the "Black" checkbox is clicked:
Toggle the display of three items (SELECT field, text (in a DIV) and an INPUT) Reset the value of the INPUT field (and reset a different INPUT when the checkbox is clicked again)
My current code
The code I'm currently using in the PHP form is below (truncated for readability):
Code:
<input type="checkbox" name="black" onclick="togglecontent('colour_box','colour_price','color_quantity','quantity_reset')" /> Black
[Code].....
Currently I can hide the SELECT and accompanying text when I check the "Black" checkbox, but it won't reset the INPUT value nor hide it. I've not yet attempted to do unhide and hide the Black text and input since I can't get this part working yet.
