I'm trying to set a variable which a remote page can access. I can do this, but I need to set this variable inside "window.onload = functio(){". When I do this the remote page can't access it. This is a breakdown of what I'm doing:
Code:
var attrIndexes = [];
$.get(queryString, function(data) {
attrIndexes = data.split(",");
});
after running this code the original variable is empty so something is wrong

I've got a function displayResults(imageArray); that first calls removeElements(); to get rid of the currently displayed list items. Both functions are part of class function eventBox(array, string, date). both displayResults(imagearray); and removeElements(); have been bound to eventBox(); by e.g. this.removeElements = removeElements;
However, from within displayResults(imageArray); this.removeElements(this.identifier + "eventsul"); evaluates to "undefined". Also, this.identifier called from within the function also evaluates to undefined (it doesn't in other functions). For some reason I can't access global functions and variables from displayResults(imageArray);. Any ideas?
Here is the code for displayResults(imageArray); :

View 1 Replies View RelatedHow to make html consistently see js functions. Let's say I have two functions in my javascript code. I want to move between the functions using html links or image maps, e.g. I want to trigger a certain function when clicking on a certain part of an image.
The problem is that when I start the function via "javascript:function" and then I want to trigger another function in the same way, I get an error message saying the function is not defined.
Below is a simple code illustrating what I mean:

I just started with jQuery and AJAX so I'm hoping that I'm just missing something obvious. I have a comment field and I have already finished all the functionality of allowing users to add comments to the page using an AJAX form.
The problem that I have is that the comment <div> itself has some rollover properties for edit/delete so that those links only appear when the mouse enters the comment div. For whatever reason, they only appear on comments that existed on the page load. Any comments that are added while on the page aren't accessible to jQuery until I reload the page. Is that normal behavior?
I am building a custom shirt design app which uses an Ajax form to allow a user to upload an image, and once it is uploaded it is automatically placed in the next empty <li> in their little gallery... once it is in the gallery they can click on it and insert it into their shirt design. It's all done with Ajax so they never leave the page.
Here's the code that inserts the image into the page once it is uploaded: (this works perfect)
$('#last').html('<img src="uploads/' + filename + '" />');
Once the image is in their gallery, the user can click on it which inserts it into their t-shirt design:
var selected = $(this).attr('src');
$("#container").html('<img src="' + selected + '" width="40" />');
Okay so say their gallery already has 5 images in it an they upload a 6th, the HTML looks like this on page load:
<li class="graphic"><img src="uploads/monkey.png'"></li>
<li class="graphic"><img src="uploads/ltdtee.png'"></li>
<li class="graphic"><img src="uploads/wordpress.png'"></li>
<li class="graphic"><img src="uploads/kitty.jpg'"></li>
<li class="graphic"><img src="uploads/steve.png'"></li>
<li class="graphic" id="last"></li>
The problem is that if I click on one of the first five, it works, the image gets inserted into the shirt design. But if I click on that last one, which now has the image I uploaded in it, it doesn't get inserted into the shirt design. Is there a reason why?
I have two Select Boxes on my web page, 2nd being populated based on selection of first select box. Now I am suppose to get the selected value of 2nd Select and put it in a link i.e.
Code:
<a href='abc.html?id=<2nd select box value>
I can get the selected value using Javascript with the following code:
Code:
2ndid = form.2ndodf.options[form.2ndodf.options.selectedIndex].value;
Where 2ndid is a global javascript variable.
How I can use this variable into <a href> tag.
i've got an html page which near the end of it has a particular image (a normal html <img src... one). is there any javascript way to stop browsers accessing that image from the server before it attempts to do so?
View 6 Replies View RelatedI have an HTML file input control, like this:
Code:
<input type="file" id="FormsFileSelector" name="FormsFileSelector" size="40" maxlength="1000" style="width: 382px; white-space: pre;"
accept="image/gif,image/jpg,image/jpeg/,image/tiff,image/bmp"

And it does indeed allow the user to select a file on his computer.
But when I access the value of the control I get an odd value. I do this, in javascript:
Code:
var FileSelector = document.getElementById("FormsFileSelector");
var FileName = FileSelector.value;
And the FileName that I get is "C:/fakepath/MyPicture.jpg"
The actual path is C:/MyDocuments/MyPictures/MyPicture.jpg". But instead it's coming up with "fakepath".
Very weird! How do I get it to return the actual full path to the file on the user's computer?

View 8 Replies View RelatedI have been working on a few budget scripts that I can access from the web in using HTML. My problem is that when variable values change I need to change these values in all of the HTML files on the server. I know that there is a way to declare global variables in a single file and use those values in another file but I have not been able to find any information that tells me exactly how to do this. I have tried to put it together on my own using what little informaiton I have been able to find but have not been able to get this to work. Is there a more detailed referance that I can find somewhere or does anyone know what steps I need to take to make this happen?
View 13 Replies View RelatedI have an external js file used by an html page but I want to use global variables defined in the html page in the js file. for example...
<html>

<SCRIPT type="text/javascript"
var test = "1";

So I have var test which is defined in my .html but my jscript.js also uses the variable. I am doing it this way because I have a lot of pages that are simular using the jscript.js functions but each page has different quantities and values of variables used.
I need help getting variables in an external js file to transfer to the html page that uses them. I have an html page that lists verses to memorize, which, when the mouse hovers over a particular verse, a small popup reveals the book reference for that verse, thus giving a check to see if the user has accurately referenced that verse for its source.
I have an external js file (VERSES.js) that houses the verses and popup references sequentially as elements in an array and then writes them to the html document. A simplifed version of what I am using, with only a few verses listed here as an example, and that works beautifully, is given below: Code:
