Getting A Specific Function To Be Available To Multiple Objects?
Feb 9, 2009
I want a specific function to be available to multiple objects.In the script, if it says 'document.Form.Input.value' with 'Form' being the form name and 'Input' being a form element, how can I change this so that I can have two different forms with elements and the function will be able to work for both?
I would like to have page which uses a few xhr objects and automatically (after 30 seconds) starts the same few requests again It works for me well in IE7, IE8, but not IE6 (where is in browsing history chosen option "automatically" ). It works there only for first time and I can't set it for circular reloading. It looks like page is reloaded, but xhr objects are not doing their job ...only - as I wrote - for first time after page load.
I basically have several buttons that are created dynamically via a db, so I can have 1 to 40 etc. now at the moment I give each one a unique id and a hover code in the loops. see below:loops goes here..
I was wondering if there is a way to simplify or clean up the code, since they are all doing the same thing and responding to the same event. This is just for refactoring reasons because my code is getting too long/messy.
I was wondering how you would list multiple variables after a equal ==? Example.... if ( pathname == schoolinformation, chaplainchatter) $('#button_newspress_archive,#button_tech_college,#button_parent_portal,#button_transition_portal,#button_6th_form,#button_connect,#button_vacancies,#button_vle_login').css('display', 'none'); $('#school_information_sub').css('display', 'block'); if ( pathname != schoolinformation, chaplainchatter) $('#school_information_sub').css('display', 'none');
Or even list multiple URL's within the variables? Example .... var schoolinformation = '/st-paul-s-website/school-information/school-news/headteachers-headlines', '/st-paul-s-website/school-information/school-news/chaplain-chatter-headlines';
I have this code <script type="text/javascript"> jQuery(document).ready(function(){ $("select").click(function(){ alert($(this).attr('id')); }); }); </script> <FORM><select name="category" id="#link1"> <option value=1>1</option> <option value=2>2</option> </select></FORM> <FORM><select name="category" id="#link2"> <option value=1>1</option> <option value=2>2</option> </select></FORM> <FORM><select name="category" id="#link3"> <option value=1>1</option> <option value=2>2</option> </select></FORM> When I click on any of the select fields, I always get 3 subsequent alerts, each with the id of the clicked select field. What I would like is to have only 1 alert with the clicked select id, whenever I click it.
I have a set of functions that will transition/fade photos in and out as background images. Easy. But now I would like to run the same functions on a different html page with different photos (each different page represents a different JavaScript array).
I've been reading online on how jQuery methods can be called into functions. So my thought process is to create 2 methods (1 for the original images and the 2nd method for the other images).
So here is my base code which works... $.landingpage = function() {
/*Enable background image cycles on landing page*/ var images=new Array('/image01.jpg','/image02.jpg'); var nextimage=0;
the situation: I'm building a web page, and the client wants to have three flash galleries on staggered timing (i.e., the first one loads and runs, 4 seconds later the second loads and runs, 4 seconds later, third one loads and runs).
I've been trying to figure out how to use Javascript to handle the initial delay between each object, and the best I can figure is to use an onLoad to start the first flash (Flash1), and then call out a function with setTimeout to start Flash2 4 seconds after Flash1 loads, and the same thing for Flash3. However, my attempts thus far have failed, and all three load up at the same time.
Must you use the keyword "new" whenever creating a new object? I was sure the answer to this was yes, but a friend was telling me in this example: var newDate = new Date(); alert(newDate); The word "new" is unnecessary and that the system date would be assigned to newDate regardless. Is this true for all objects? Some of the time? Never? I've always understood that "new" was necessary and never questioned it.
Is there a way in Javascript or Jquery to return an array of all objects underneath a certain point, ie. the mouse position. Basically, I have a series of images which link to various web pages but I have a large semi transparent image positioned over the top of the other images. I want to find the href of the background image that the mouse pointer clicks over.
ive got this function here which i nid to get a specific variable out from it so dat i could pass it to another function. ive tried many ways bt still cant do it, including using global var and function call.
var textFile = 'preferedChannel.txt' ; var testChannel = 'This is a test channel' ; (function(f) { $.get(f, function(resp) { resp = $.trim(resp); // Variables to get current day and time in 24hrs format [Code]....
But I was wondering is it possible to make it so that if you visited an anchor link: For example, let's say you visit:
Code:
[URL]
Then a code would run to let's just say... change the color scheme of the website. (And theoretically they same would happen with #v2/#v3, ect)
But the code would NOT run if the requested URL is just
Code:
[URL]
The reason I was wondering is I want the user to be able to "bookmark" a certain script per-say, so that when they revisit the site they don't have to reclick things to get back to where they were before.
I was wondering if it was possible to call a specific PHP function using AJAX instead of calling a whole page. An example:
function MakeRequest() { var xmlHttp = getXMLHTTP(); xmlHttp.onreadystatechange = function() { if(xmlHttp.readyState == 4
[Code]...
I already have a PHP function (in a class) that retrieves the provinces/states from the database based on the country. I was wondering if it was possible to call this function instead of having to make a new file (in this case FindProvinces.php) that calls the function.
Just getting my feet wet with AJAX and trying to figure out how I can make a javascript call to a specific PHP function in another file when I have a drop down menu change value using DOM. I've found lots of examples of how it could be done with GET variables, but none for this particular method of data retrieval. Has anyone ever ran into this, and if so, how did you solve this interesting deliema?
I have an image map with various areas on it. A user can click on the various areas and something happens. That said, I sometimes need to disable the ability to click on some areas. For instance areas whose id attribute contains 0 0. I have the code to split the id and grab whether the values are 0 or 1 and the alert pops up when one has 0 0 in the id but it's still clickable. I thought .unbind would do the trick, but it isn't. The alert is simply for testing.
$('area').each(function(){ // Use the each() method to gain access to each elements id var idToDisable = $(this).attr("id");//get id of area var splitID = idToDisable.split("_"); if (splitID[3] == 0 && splitID[5] == 0){ alert(splitID[3]+splitID[5]); $(this).unbind('click'); }else{ }});
What is happening is $(this) is no longer based on .expand being the (this) that is clicked.
like if i have a button SOMEWHERE randomly on the page with this
<div onclick="Minimize('_alerts');">Click Here</div> this will minimize alerts but because the (this) in minimize function doesn't actually point to the right button that I want to add a class to.
Is there a way to modify the minimize function so that it finds the <div id="mytoggle"><ul> <li class="expand boxminimize" rel="_alerts"> using the rel toggle, and then changes the class of the li from expand boxminimize to boxexpanded??
just like the .expand click function I posted on the top of the post that works?
Another thing that has been driving me crazy is that css positioning is handled differently by different browsers. JS is not my area, but I can do a lot with CSS, and I do, but cross browser compatibility is killing me.
I can use an IF IE statement and only IE runs that segment of code, but I haven't been able to figure out out how to make ONLY firefox or ONLY opera or safari enact an encapsulated segment of code. The same type of IF statement doesn't work for them.
Is there a single method using JS that works for all browsers?
function result(){ var result = document.getElementById('resss').innerHTML; }
But what I actually want is to import data from a table of an external website. E.g. I want to get the innerHTML of a specific cell in column 3 and row 2 of a specific site.
