JQuery :: Passing Local Variables To Callback Functions?
Jun 2, 2011for some time I always found a workaround for this kind of problem. But somwhow, it feels wrong. So I'd like to know, if there's a common way to solve something like this[code]...
I'm defining the function and if the value of 'obj' hasn't until the function really gets called, this can work. But it just feels so wrong do have always global variables just to access them inside of a callback.[code]...
JQuery :: Encode And Submit Local Variables Via Ajax POST?
Jun 12, 2010I have acollection of local variables populated via Flash movies and scripts, and now I need to submit an ajax post (can also be get, but prefer post). I have tried:
$.ajax({
type: "POST",
url: "/myurl",
data: "p1=" + localParam1 + "&p2=" + localParam2,
success: function(msg){
alert( Bingo: " + msg );
}
});
The problem with this is the encoding of the localParam1 and localParam2 sometimes breaks the normal & delimeters. An even more problem is I sometimes haveupwards of 25+ local variables that I need to submit. These inline +s makes it feel, and look, like one huge hack - not to mention the encoding. One last restriction: I cannot use any jquery plugins due to the company's policy. So, I'm looking for something small and light as a solution - not a plug-in. Isn't there an easy way to do this? ONe thought I had was to create a new <form> on the page, and insert the variables as new <input /> fields - and then finally submit the entire form. Again, a big hack + css
Local (var) Variables At The Top Of Function?
Jun 15, 2007In jslint's doc it says, "JSLint does not expect that a var will be defined in a block. This is because JavaScript blocks do not have block scope. This can have unexpected consequences. Define all variables at the top of the function." What are some of those unexpected consequences?
View 1 Replies View RelatedAvoid Temporary (local) Variables To Reassign This?
Nov 14, 2010how to avoid temporary (local) variables to reassign this.Example as follow:
function Test(id){
this.id=id;
this.init=function(){
// some initialization go here
[code]....
This is terrible because it breaks the structure, and so many local temporary variables will be instantiated (possibly they will eat up the memmory).However, this type of reference is just so popular in jQuery, and they got a beautiful solution. Example:
$('li').each(function(){
// Do with $(this). This is beautiful, but I don't understand how could they make this scheme.
})
Opening Local File In New Window?

View 1 Replies View RelatedPassing Variables From One Window To A Newly Opened Window
Jan 3, 2011Here is the program: [URL] Basically, I want to input a number in the input box, which assigns a number to the variable numval located at document.box1.b1. When clicking on the "new window" button, an alert displays the input box value, then another window opens and displays the integers 1 through 12 and the amount squared.
I would like the new window to obtain the number from the previous window so that the new window will display integers (and their squares) from 1 to the value of numval.
JQuery :: Cannot Iterate Through Table

JQuery :: Iterate Through All The Dropdownboxes On A Page?
Sep 4, 2010I'm trying to iterate through all the dropdownboxes on a page without much success! What I'd like to do is store the selected value for each of the dropdowns, separated by commas in a variable when a button is clicked. Each of the dropdown boxes 'id' begins with the string 'attrib-' which is how I'm trying to identify them.
I've managed to hide all the dropdowns with this code:
jQuery(document).ready(function() {
jQuery("#myButton").click(function() {
jQuery("[id^=attrib-]").hide();
})
})
So I thought I could do something similar to get the selected value but I can't figure it out.
JQuery :: Iterate Over A Checkbox Group?
Jan 29, 2011I have a form on which I've created 5 checkbox groups. Each of these groups consist of multiple checkboxes. The first group - it's id equals "MASTER" - contains 4 checkboxes. These checkboxes are labelled (that is, their actual label tags are) "A", "B", "C", "D". My vision is to have a user check, say, "A" in MASTER and this causes the "A" checkbox group to appear below the MASTER group. If a user then checks "B" in MASTER, then the "B" group appears below the "A" group. If the user then unchecks "A", then the "A" group disappears. And similarly for each of the four "subordinate" groups. My plan of attack was to iterate over the MASTER checkbox group, and for each checked box, somehow populate an array of their associated label tags. I would do the same for all of the checkboxes in MASTER that are not checked, placing their label tags in another array. I would then show and hide the subordinate checkbox groups based on these label tags. The subordinate groups have label tags equal to these captured label tags in these two arrays. All of this action would be triggered via a "click" action on the tag in which the MASTER group resides. I've tried all manner of techniques, including "$.each" and ".map" to populate arrays. I just can't get my mind around the needed syntax.

Jquery :: Iterate Certain Classes Over Elements
Dec 21, 2010In my page I have pairs of divs like this:
Code HTML4Strict:
<div class="rounded red">
<p>Integer egestas neque vitae dui ultricies vel venenatis mi varius! </p>
</div>
[code]....
This works,in that it at least added the new class whereas the other solutions didn't. Unfortunately it counts EVERY div, not just the ones with the class .client, I can't set my array of desired classes, and I have no idea how to make it restart the count after it hits #4.
JQuery :: Can't Iterate Through SPANs And Execute Ajax GET
Jul 16, 2009As soon as the page loads, I would like to iterate through several span tags on the page and update their innerHTML to be the response from the AJAX get call. The line I have commented out, alert("Data Loaded: " + data);, works perfectly, but creates a bunch of alert boxes (which I don't want). And if I move the line "this.innerHTML =data;" out of the Ajax call, it works fine also. So I know all the syntax is correct. But when I put it together as outlined below, it just won't work. The Ajax is working, I also see the GET calls working fine in the Firebug console. It just won't update the innerHTML of the SPAN tags.

JQuery :: Each Function Iterate Through Form Inputs
Oct 23, 2009I cant get this each function to work inside a form: For example I have this code:
$('#formid>input').each(function(){
if($(this).attr('id')!='') alert($(this).attr('value'); //fetch id if
not blank ang show value
});
The code inside this function does not run if the form is rendered this way:
<form><div id='tabs" >
<ul>...</ul><div id='tab1">
<input type='text' id='fname' /></div>
</div></form>
But if it is rendered in a simplier way like this, it works:
<form><input type='text' id='fname' /></form>
I am using jquery jquery-ui-1.7.2.custom.main.js library by the way for the tabs but I don't think that messes up the whole thing though...

Setting Variables In Another Window
Jul 20, 2005I'm trying to create specific pop'up window (for product category
selection), but in JS I'm a newbie
and some problem occured, so I have a question:
Is it possible in main window (that opens a popup) to set in popup window:
1. global variables
2. form fields
For example, I'm opening popup window like below:
categories=window.open(address,"categories","scrollbars=no,height=400,width=
600");
Then I try to set global variable in popup window:
categories.global_variable = 1; //no effect
Or try to set form field:
categories.document.some_form.some_filed.value = "some value"; //no effect
If none of above won't work, how could I pass some data to another window
using JS?
Passing Variables From One Window To Another
Apr 18, 2005We have a content management system that requires us to fill in 20 fields for metadata about a page. We store the metadata in a separate database for our records.
I'd like to be able to open a window with the data from our database, click a link, and have it fill in the form in the content management system (hosted by a different organization, so window.opener is out of the equation).
I tried this
<a href="#" onClick="window.open('http://www.google.com', 'Google'); window.Google.f.q.text.value='my name'">Enter my name in Google!</a>
In this example, I'd click a link that would open up Google, then pass the value "my name" to Google's search bar. Unfortunately for me, it didn't work.
Am I asking too much? I'd hate to have to rekey or copy/paste 20 fields worth of metadata each time I create a page.
Window.open With Url Variables?
Jul 11, 2011i have this code:
echo "<script type='text/javascript'>openWindow('".$adress."')</script>";
the $adress send an url with variables like "xpto.com?var=1&varB=2"
Problem is that using window.open always encodes & character to & and the url doesn't open. I have tried many functions but still doesn't work.I have this javascript code:
function convert(str)
{
str = str.replace(/&/g,"&");[code].....
The convert function doesn't do anything. the commented javascript functions like unescape, etc also doesn't work. If i do alert(adress) it converts & to & but if i do document.write(adress); it shows correctly. So i assume that some functions encode and others don't. Meaning that window.open encode by default. It there a way to override this?
