JavaScript - Get The Number From A Remote Webpage
Similar TutorialsI have a function below where every time a question is submitted, it will add a new row in the table with a textbox which allows numbers entry only. My question is that I don't know how to code these features in this function: 1: I want the text box to be between 0 and 100, so if text box contains a number which is above 100, it will automatically change the number to the maximum number which is 100. Does any one know how to code this in my function below in javascript: Code: function insertQuestion(form)
{
var row = document.createElement("tr");
var cell, input;
cell = document.createElement("td");
cell.className = "weight";
input = document.createElement("input");
input.name = "weight_" + qnum;
input.onkeypress = "return isNumberKey(event)";
cell.appendChild(input);
row.appendChild(cell);
}
When I used toFixed() method on a number, I thought that this method round a number to a specified approximation, but I got a surprising result, the number became string! 15.23689 .toFixed ( 2 ) ==> "15.24" So does it convert the number into string? I am trying to figure out how to make a random number I can plug into a script count down from that number at certain times of the day until it reaches 0. I would like it to reset itself at midnight every day. I'm trying to make it work with a script I found on here that resets itself at midnight every day. So instead of it counting down too fast, it would count down to the next number after a randomly generated number of minutes until it reaches 0. But it wouldn't necessarily have to end at 0 at midnight. It could go from 845 to 323 at the end of the day at a slower pace. Is that possible?
Hi, I am hosting my website in free server (freehostia.com) and i am using joomla1.5 . I want to parse RSS from my other websites. Joomla does it with its modules. But the server do not allow outbound HTTP request, hence i had use rss-to-javascript website to parse RSS feeds. It parses well but there is its advertisement below the feed (which i think is nonsense). The link it provides is in the format of <script src="http://somethin.com/somdfile.php?parse=.."></script> when i put the link in my browser i see following document.write("string of my parsed xml file with advertisement at end"); What i want to do is get the sting of above line and edit it to chop off the end advertisement. if there was any method to load that output sting in any variable, the task would had been completed. If anybody knows how to do it, please help me. I have a google blogger site on which I want to run a PHP script. The problem is that blogger doesn't have a PHP interpreter. So I was thinking, can I run the php file on a remote server that supports php, and load the result in a div in blogger? Thx! Hi, Im trying to load a remote script but only if a statement is true.. Code: <script type="text/javascript">
var width=screen.width;
if (width>1023);
{
// load remote script
}
</script>
How would I go about this? And will it work if the script in php? Thank youu! EDIT: I realise its probably not the best practice but at the moment im having to use Code: <script language="javascript"> window.location.href = "index2.php?width=" + screen.width; </script> and on index2.php Code: <?php
$res=$_GET['width'];
if ($res > 1024) {
include("header.php");
}
?>
Hello, I'm building a very simple app that relies on a remote server. I will use this app on many websites, so I decided to store it on one server (I have control of the remote server in question). I need to make sure that this server is up and running, so in the case it's not I can use a fallback. Would it be a client-side approach? A server-side approach? My guess is to use a js snippet to do the job. If I'm correct, I'll probably use jquery to perfom the task. Regards, -jj. Is there any way to check if exists a cookie from a domain2 in domain1? The purpose here is if the cookie from domain 2 exists then do an action in domain 1. For example: Erase cookie or do an action. I have discovered a XSS vuln in a website and I'd like to use this as a cookie grabber. If you can help, <removed>.
If I use a window opener to open a new window, is there a way to detect that the new window is finished loading before carrying out some other directive in the opener window? Can I access the remote window's onload event from the opener window? I need to know that the website has loaded before moving to the next page. something like: remoteWindow.onload = goToPage(url); Is this even possible? HI I'm new to tinymce. I'm using tinymce with jquery validate with remote Methods. (Remote Methods: http://docs.jquery.com/Plugins/Valid...Methods/remote) I'm using jquery validate to check if email address already has been enter into the database, once it check the email hasn't been entered.

I have tried googling the syntax and not having any luck. Thanks, Blake Hi please help me with this website.

I am delving into the coding world and while I understand the basic principle of cookies, conditional statements, arrays, etc... I am still learning how to properly implement them. Any asistance with the following situation would be greatly appreciated and help with my learning as I try to reverse engineer the logic. I have looked around the web and this forum with little success. If the situation below is too complicated, I would really appreciate even a shove in the right direction regarding the logic. ----------------- How could I show a preset counter which counts up from a preset, beginning number toward a preset, end number? I imagine the increment and speed is set be the difference between the two numbers and a timeframe. Assumptions: I would rather not set the increment but edit the end number to show a steady increase. As I update that number, the increment adapts dynamically. I would want the number/script to be useful, so it should not refresh to the beginning number on each page load (i.e. num=0). When a visitor comes to the page, it must seem like the counter has been steadily been increasing in their absence. Coke or Pesi did something similar one time regarding cans sold to date (doubt it was plugged into a DB somewhere but rather based on a steady sales figure) and it was pretty cool. All the best! I maintain a website for a small local restaurant. I do this with FrontPage so I know very little coding. I have an upload manager so the owner can remotely upload a txt or doc file of daily specials to a folder on the server. I would like to put a java script into one of the web pages that would open and display this file on page load. Is that possible and can someone help with the code, Thanks Hi, Can someone direct me to what do i need to get something like this going: When a user clicks on a button to focus a windows program thats already running Thanks |
