JavaScript - Edit Latest Tweet Javascript To Read Xml Database?

Hi,

i have a question, is JavaScript can read an external file? i have an ear file, can it read external file without the external file compile together in the ear file? can we do so?

This is a must-read for all users posting to the JavaScript forum, especially if you're looking to get help. A lot of you are posting in a manner that makes it extremely difficult- if not impossible- to respond to. Below are a list of posting guidelines and tips we ask that you please read- and FOLLOW- when asking for help:

1) Type in a subject that summarizes your question! - The fastest way to turn off other members wanting to help you is to type an incomplete or silly subject for your post. Examples of poor subject titles include:

- "Help!"
- "I'm a newbie...please!"
- "Is this possible using JavaScript?"
- "loops"
- "Urgent...deadline tomorrow!"
- "A challenge for you JavaScript masters"

The above subjects either have absolutely nothing to do with the question itself, or are grossly incomplete (ie: "loops"). When asking for help, enter a subject that summarizes your question, period! Don't use silly, incomplete, or "bait" subjects.

2) Be descriptive and articulate when asking your question! Some of you are posting as if we're all psychics, and are supposed to grasp your question with the little or confusing information you've provided in your question. We cannot read your mind, and putting up a post like "Can someone help me with arrays?" or "How can I get the slide-in slideshow to work on my site?" is not nearly enough information to go by. What exactly do you want to know about arrays? Which slide-in slideshow are you referring to (the one written by Bill Gates?)? Set us up with some crucial background information, what you want to do, and what the problem is. Be concise and precise.

Also when posting, understand that you're trying to convince others to help you. Be articulate and have respect for the English language! Check for spelling/grammar mistakes, and try and format your question and code in an easily legible manner. Big tip: Use the preview button often.

Bottom line- put yourself in our shoes, and try and phrase the question so it's clear and easy to respond to.

3) Do your homework first. Only post the part of the script you're having trouble with! There are generally two types of people- ones that simply dump their entire page or problem and expect everyone to spend hours solving everything for them, and those that do their own homework first, and only ask very specific, manageable questions. The later invariably gets more and better responses from others. When you're lazy, do not expect us to be hardworking for you.

As an example, lets say you're working on a long script that uses the "switch" statement of JavaScript, and it's returning errors. You could either:

i) Post the entire script and simply say "Please debug this script for me!"
ii) Or, localize the problem yourself first and post instead "Can someone tell me the syntax of the switch statement in JavaScript?"

The second question will get a LOT more quality responses, as it is concise, manageable, and not overwhelming. Remember, ask for the world, and you'll get nothing. Ask for a little, and you'll get a lot.

4) Use the search feature often to make sure your question isn't already answered- The longer this forum has been online, the more solutions it accumulates. Always search past posts first (using the search link to your upper right) to make sure your question isn't already answered. Use 1-2 keywords as the search terms.

5) Know the capabilities and limits of JavaScript before posting. Please familiarize yourself with what JavaScript can- and cannot do- before posting. Many people are posting JS questions that simply cannot be accomplished using the language, period. JavaScript is a client side language, and cannot manipulate the server end in any way, such as saving data to the server, accessing a database etc. JavaScript works strictly on the user end, such as popping up a window, applying an image rollover effect, or determining user screen resolution (*without* the ability to pass this info back to the server).

If JavaScript is completely new to you, please familiarize yourself somewhat with the language, by visiting the below links

- JavaScript questions and answers list
- JavaScript tutorials
- Advanced JavaScript tutorials
- Pre-made JavaScripts (illustrates typical JS applications)

6) Be appreciative and follow up when getting a response. Everyone here is volunterring their time to help out others. The least you can do is be appreciative and follow up when getting a helpful response. If you've solved your problem, let people know so they don't continue spending time on your question. Saying a little "thank you" goes a long way.

I am having trouble with JavaScript code and do not know why it is not working. I have the code I think is right but it is not showing up in my browser when run. Any ideas?
Also are there any other ways to read in an xml file using javascript? please list if so.

I wants to access server web page which data is continuously growing(streaming data), I want to buffered some of that data write it in responseText then again get next buffered data write it and so on (in AJAX).
Is it possible? if yes how to do that?

Hello,

Is there a way with JavaScript to easily detect which mobile browser is being used? I would not normally ask this, but because we do not have the time or budget to implement any back end detection scripting it is our only option right now!

I don't think we will need to detect which version of the browser, or which revision of the phone is used - just need to target each family to deliver the proper video type.

hi ,

Hi,

I am Aditya. I am explaining below the exact scenario where I need the help:

I am developing a web application in which I need to integrate a javascript/html editor on some of the web pages and then provide 'Edit' buttons on those web pages so that users can edit the content on that partciular html/jsp page (like editing in wiki pages) and then, when they add some content and click on submit button, the new content should appear on the web page with all the formatting (i.e. bold, italics, color and so on) which was applied by user when he was entering the text.
Now, I need help for the below issues:
1. Please suggest me a good javascript/html editor (freely downloadable) which I can use to integrate with my web pages.
2. Once the user has entered some content using the above javascript editor, how to make that content reach the server and update the corresponding web page.

I am new to web development, so may be that these questions are too simple.
But, I need some help from you.

Waiting for your reply,

Thanks,
Aditya

If you watch this page http://wouldbebetter.com/

for about 15 seconds, you can see that new "suggestions" will be shown as they are submitted. How can I do this with a post system?

Hey guys, so i have a site iv created for a client.

Hi,

i have a rating script which shows 5 stars and it allows users to vote out of 5 on certaiin things, the votes register ok but the stars dont change colour to show that the user has voted.

this has happened since my host upgraded to php 5.3 and i noticed on IE(which i never use much) it says there is an error on the page and that error says

Code:

Webpage error details

User Agent: Mozilla/4.0 (compatible; MSIE 8.0; Windows NT 6.1; Trident/4.0; SLCC2; .NET CLR 2.0.50727; .NET CLR 3.5.30729; .NET CLR 3.0.30729; Media Center PC 6.0)
Timestamp: Tue, 2 Feb 2010 20:00:42 UTC


Message: 'document.all[...]' is null or not an object
Line: 96
Char: 9
Code: 0
URI: rating.js

line 96 in the related file is
Code:

    }  else if(IE) {
        document.all[div2show].innerHTML = text;
    }

which only related to IE and not firefox so im unsure why my rating graphics do not show once selected.

here is the entire js file is there anything in there that might be preventing it?
Code:

This is puzzling me.

It's an incremental search function. Any help for a Javascript novice much appreciated:

Code:

$(function () {
    $('#quickFilter').incrementalFilter({
        items: 'dl.entryList > dt',
        foundCounter: '#resultCount',
        totalCounter: '#totalCounter',

Okay, I'm good at PHP but using javascript so the user doesnt need to refresh the page is a neat thing.

I want to make a button that says "Do you like this game? Yes or No"

How can I use javascript to tell Yes to send

games->rating_yes = 1
or
No games->rating_no = 1

Or if you could link me with resource on building something that can teach me how to use javascript to update/insert into my database.

I've tried stuff like this

Code:

Do you like this game? <a href="javascript://" onclick="ajaxYESorNO('<?=$gameid;?>','like');">Yes</a> or <a href="javascript://" onclick="ajaxYESorNO('<?=$gameid;?>','dislike');">No</a>

Code:

function ajaxYESorNO(gameid,answer) {
	ajax = ajaxFunction();
	ajax.onreadystatechange = function () { ajaxRateGame_stateChanged(vote); };
	var url = base_url+ "includes/ajaxYESorNO.php";
	url = url+ "?vote=" +answer;
	url = url+ "&gameid=" +gameid;
	ajax.open("GET",url,true);
	ajax.send(null);
}

PHP Code:
<?php
$gameid = $_GET[gameid];
$vote = $_GET[vote];

@include "config.php";

if($_GET['vote']=='like')
{
    $result = $GLOBALS['dFetch']->exec ("update games
                        set rate_yes=rate_yes+1
                        where gameid = $gameid");
} else {
    
    $result = $GLOBALS['dFetch']->exec ("update games
                        set rate_no=rate_no+1
                        where gameid = $gameid");
}
?>

But yet cant seem to figure how to get it working properly

Thanks.

ok this is all hyperthetical and ground work (phishing) for me so any and advice will be warmly welcomed.


I would like to start and e-commerce site BUT:

I'm sure i should use javascript on client side to validate an order form BUT

1) server side, how is the order revalidated --- ie is javascript used again on server or use of another language?

2) could someone explain how information from order form is connected to an (SQL) database ---- and how is that database then updated?
What language is used? (I am talking about the general process here)


At the momment i'm researching SQL
http://dev.mysql.com/doc/refman/5.5/...ving-data.html
and e-commerce database design
http://www.princeton.edu/~rcurtis/ul...mdatabase.html


but I have no idea how all this is connected and where Javascript finishes and where I need to research further in oreder to put things together.


Any help would be fantastic

sorry for the novice questions.

Hi,
I want to access SQL database using javascript.

I am passing 1 value to the java script but I want to pass that value further to the SQL query as an where clause parameter to retrieve data.

If the value retrieves multiple or single data then how do i handle it.
Is it possible to use dataset in javascript?

Regards,
Anthony.
