JQuery :: Accessing Variable Earlier In Page?

Feb 3, 2011

We have a web site provided by the software company that created our vacation rental management software, so, as such, I don't have entire control over the pages -- just bits and pieces. They recently started including jQuery 1.4.4 along with jqueryUI and cookie plugin on the pages and utilizing it a bit (as well as a custom jquery bit of code they wrote up). here's the relevant code (that I have control over):

HTML Code:
<script type="text/javascript">
var phoneflat = $.util.getCampaignPhone('MCPH').replace(/[^0-9]/g, '');
if(phoneflat=="null"){var DNISPh='88812345678'}
else{var DNISPh=phoneflat}

[Code]....

Basically, we have a phone-number tracking system on our Web site, and the toll-free number on our site gets replaced depending on how the MCPH cookie is set. The above code pulls formatted number from that campaign cookie, removes the formatting from the number, and sets the pop-up URL to include the number, passing the number after the "?DNIS=" (which is required for this specific campaign tracking to work properly).

This all works fine and dandy if the jquery and cookie code is all before the above code snippet on the page, but the developers of the software are trying to follow best practices and are loading all the javascript files at the end of the page, and this is far earlier in the page. So there's really no way for me to pull that ".util.getCampaignPhone('MCPH')" as the cookie may not have been set yet, nor is the campaign data ready.

Jquery :: Accessing Object Using Variable String

May 8, 2011

I have an object whose name is mural. I have assigned the name mural to the title of an anchor element. When user clicks and element I want to store the title of the anchor in a variable called sprite. I then want to access that object whose name corresponds to the sprite variable string.

Here is my code:
HTML Code:
var mural= new Object();
mural.top='0px';
mural.left=-'510px';

var stamps= new Object();
stamps.top='0px';
stamps.left=-'1886px';
var sprite=$(this).attr('title');
$(".image-holder").css("background-position",'sprite.top, sprite.left');

It's not working because the the variable sprite is just a reference to $(this).attr('title'), how do I make it reference the object? Oh and I know that .cc jquery statement probably wont work, I'm not sure yet of the correct way to have two values that don't need quotations in as the second argument.

JQuery :: Ajax Post - Accessing Return Data / Result Variable

Nov 30, 2010

So I'm currently working on a ASP.NET Webforms site and I've run in to a small problem. On my .cs file I have the following Webmethod

[WebMethod]
public static string IsJobEditable(int jobid){
try{
string isEditable = "false";
JobsBLL jbl = new JobsBLL();
int jobStatusId = jbl.GetJobStatusId(jobid);
//If the jobs is either waiting or being edited it is
okay to edit it
if(jobStatusId ==
Convert.ToInt32(ConstantsUtil.JobStatus.Waiting) || jobStatusId ==
Convert.ToInt32(ConstantsUtil.JobStatus.Edit)){
isEditable = "true";
}return isEditable;
}catch (Exception ex){
throw ex;
}}

This function in this case will ALWAYS return TRUE as a string. On Aspx page I have the following
$(function () {
$.ajax({
type: "POST",
url: "Coordination.aspx/IsJobEditable",
data: "{jobid:" + jobid + "}",
contentType: "application/json; charset=utf-8",
dataType: "text",
success: function (result) {
alert(result);

//This is written out in the alert {"d":"true"}
I want this in a variable as a string so I can do a check on it before I do some other actions. The format is not a String so I cannot split on it to retrieve the "true" part.
},
error: function (err, result) { alert(err); }
});});

As you can see in the comments the value I get back in the Callback method is in to me a weird format. The type is unknown and I need this value to be able to proceed with my entire method surrounding the small portion of the Javascript. Where to access the result variable / data as a var or anything else that will let me put it into a var (as a string).

Accessing A Variable Through A Form Name

Jul 23, 2005

I have 2 arrays:

var A1 = new Array();
A1[ 0 ] ="Y2";

var B1 = new Array();
B1[ 0 ] ="Y1";
B1[ 1 ] ="sink";

I also have a drop down menu with the names of the arrays. Say:

document.form.option[1].text returns 'B1'

Can I transform the string 'B1' into the array B1, so that:

document.form.option[1].text[1] returns 'sink'

Currently I'm doing this with conditionals, e.g.

if(document.form.option[1].text =="B1){do stuff}

but this gets a bit messy.

Accessing Value Of String Variable In Assignment

Sep 26, 2011

I am new to Javascript but fluent in C++ and other languages, I have a query, I made a global variable to hold string information, can the value of this string be assigned to a form input field value? I mean in the 'default value sense' I am just wondering if there is any syntax to accomplish this. EG in my javascript I have the string nameVal; It is a global variable, I would like to know if it is poosible access its value for use in the line below shown with italics, or is it basically always a case of 'type the value in manually yourself' and then rely on events functions to update the field thereafter?
Name: <br><input type = "text" name = "nameField" size = "50" value = my string val here onChange ="this.value=storeVal(this.value, '0')"></input></br>

Accessing Variable In Hover Event

May 13, 2011

In hover, the structure is
Code:
$("div.x2").hover(
function(){
var a = 1;},
function(){
alert(a);}
);

If I want to access a that was set in the mouseover part of this structure, or I want to change the value of a from the second function, do I have to create a global variable that can be accessed by both or is there a way to pass this variable back and forth between the two functions since they are both within the hover event?

return ('variable_'+id) will give me a string named 'variable_id'

but how to get the value of the variable_0/variable_1 ......... by just replacing the id and looking for that variable.

Accessing Width Variable - Returns Undefined

Feb 13, 2009

I am trying to access the width variable from my main page. Within the imageinfo.js script functions I can alert() the width value which returns 1024. But I can't seem to pass this variable to my main page or access it directly so that I can use document.write() to write the variable on the page. Whenever I try to call the 'width' variable directly from the main page I get undefined. How can I access this variable? However, with the test code below, I was able to get ducument.write() to write the 'width' variable on the page but now the page doesn't stop loading - there's an endless loop in the code...

Code:
BinaryAjax(url,function(http) {findEXIFinJPEG(http.binaryResponse);test(width)},null,useRange ? [0, Range] : null);

Main page
Code:
<html>
<head>
<script>
function test(width){
document.write('Image Width = ' + width)
} </script>

<script type="text/javascript" src="binaryajax.js"></script>
<script type="text/javascript" src="imageinfo.js"></script>
</head>
<body>
<script type="text/javascript">readFileData('image.jpg')</script>
</body>
</html>

Imageinfo script - This script uses the binaryajax script found below.

Accessing Global Variable - DropDown List

Apr 3, 2010

I'm trying to pupulate a web page with javascript. I have 2 functions. One that runs on-load so I can populate a dropdown list. The second one to process the selection when the user selects an item from the list. I have a global variable in the top of my javascript that I use in the functions and as long as I set it in it's global scope, everything works fine. But what I really want to do is to pass this into the javascript running on this page via [URL]

I cannot get this to work. First here is what I have that works:
<script type="text/javascript">
weekNumber = "00"
function processSelection(sel) {.....
... [includes references to weekNumber]
.....}

function populateList() {
...
}
window.onload = populateList;
</script>
...
<select name="team" onchange="processSelection(this)">
...

I've got the code to gets the variable passed in properly:
var sGet = document.location.search;
sGet = sGet.substring(1); // Eliminate the leading "?"
var sGetPairs = sGet.split("&") //Get 1st pair
var sGetValue = sGetPairs[0].split("="); //Split it
var weekNumber= sGetValue[1]; //Save it

Where do I put this code so that I can use it to set the global variable "weekNumber"? I've tried putting this code in the populateList function. I've tried referencing it via window.weekNumber and this.weekNumber. I've spent far too many hours trying to understand this without success. Where to put this code so I can set the global variable weekNumber?

Accessing A Variable Defined In A Function, Outside The Function?

Sep 18, 2010

I'm making some changes to a google chrome extension I made and am having some trouble. Heres my code on a content script page (removeAttr.js) :

chrome.extension.sendRequest({greeting: "whitelist"}, function(response) {
var whitelist = response.whitelist;
console.log(response.whitelist);//working
});
alert(whitelist);//alerts "undefined"

How do I acess the whitelist variable from outside the sendrequest() function?

Iv tried saving it to a window.var variable with no luck. Iv tried creating a div and assigning it's innerHTML as the whitelist variable and getting it later with no luck. The fact that it's a chrome extension complicates things because i dont actually know if i can create elements from where the script is located.

Get A Variable From A Remote Page And Define As Variable?

Apr 26, 2011

I have a programing problem that have been around for ages. I have search on google using several expressions and words and after hours of digging i'm still unable to do it.I would like to get a value from a HTML page hosted remotely with an inconstant value. Then define this value and name as a javascript variable and apply or show in my page.P.S. Is there any way to make a domain lookup in javascript? I mean a user enters a domain and the script converts to an ip and shows to the user. If not thanks, probably it can only be done in the server side...
