What's The Comparable File In .js To Global.asa In ASP?
Jul 20, 2005
What's the comparable
file in .js to Global.asa in ASP to capture the browser version (IE
vs. Netscape)? Any existing code to share or if you have a better way
to do it without using any server-side programming?
Can you write:
if (navigator.userAgent.indexOf("MSIE") != -1) as Client-side
programming within a HTML file instead of in a .js or .asp file? I
tried to write this piece of code in a HTML file, but it doesn't work.
So I am wondering about what's wrong.
Does anybody know how I can have a global variable in an HTML file? for instance, I have a fuction (called aFunction() here) and during a mousedown or up event the function is going to be called.
The third passing arugment or parameter is myGlobarVar. How can I make this work? since myGlobalVar is defined in a different block of javascript within the HTML file?
I have tried to write a wait function but it seems like it will not brake the while loop. I tried two different solutions. Can anyone tell me what I am doing wrong, and come with another suggestion? If I call the function like this: wait(500); it should wait 500ms right?
function wait(time) { while(1){ setTimeout("break;",time); } }
function wait(time) { var flag=0; while(flag=0){ setTimeout("flag=1;",time); } }
i am using netbean to develop a registration form.As this i want to know what is the coding to check input of text, integer, email , so i can restrict what they input..
How can I have global variables and global arrays whose value(s) can be modified and accessed by all the Javascript functions in my HTML document as well as by the HTML code?
I need to get the object that was just clicked, to insert into a JavaScript function. I've tried "function('this')" and similar things, but it doesn't work.
I have 3 select pulldown boxes where a user will select a year (either 2002 or 2001), a week (one thru 52), and a database (short data or long data). But if a user selects a week that is less than 4, the 3rd select pulldown will only show the choice of "short data", as they will not be able to select "long data". Is it dynamically possible in javascript to program a third pull down in this fashion?
how to achieve the same affect with the code pmw helped me with several months ago this time around im trying to achieve the same affect instead of displaying one image im wanting to display text but stuff like this depending on what is selected once again it will display the following.the url for this is once again here.how much space,bandwidth,ram for gaurantee and burstable ram and ips etc.. now how can i do this using the following code below.
So I have a nice little hand rolled Ajax call to my server pulling a list from the database and displaying it in a drop down list dependant on the user input. Aka Google suggest. I am wondering if the quickest way to do this is to call the database each time with Ajax and search the results with the input, or to write an xml from the database and search that. Then when the Database is updated rewrite the xml file.
Am I underestimating MYSQL again? Or not, and I feel it would be good practice to write the xml file because it will essentially mean a lot less database calls. But I don�t know how fast searching an xml file would be in comparison to a db call. The results from the database are say 500 entries anywhere between 10 - 100 characters each. I want to know A. The best way to do this B. Lets say the site will have pretty high traffic so I am looking for it to be as tweeked as possible. I can test but thought at the end of my week it was worth seeing what peoples advice is.
If I have a global variable in one <SCRIPT>...</script>, is it available in the 2nd <SCRIPT>...</script>. I do not know if "global" means the whole document or the whole <SCRIPT>...</script> only.
I'm looking for a global array to store various integers in.
In IE and FF I always used this: window[test] = 65;
This worked fine in FF and IE, but safari doesn't play ball. I'm not sure if window[] is a special reserved array in those browsers, since I didn't even initialize it before using it, it just worked 'right out of the box'. Anyways, I tried going:
var window = new Array();
AND
var window = [];
but safari won't budge. Whenever I add values to the array, and try to do something with those values, safari says its not declared/undefined. What am I doing wrong?
function openWindow(windowName){ timeStamp = new Date(); var timeStamp = timeStamp.getTime(); document.getElementById(window).style.display = 'block' }
blahblahblah . . . openWindow('order'); // calls openWindow function and sets timeStamp variable. alert(timeStamp);
then I get error: timeStamp is undefined. Why? I defined it as a global variable within openWindow. Am I just doing this wrong?
I`m building a site with html and GIF files on one server and audio files on another. That means I have to use absolute references to the audio files.
Problem is, the site will probably dwell some day in other server(s), and may also use a different audio format. I like to be able to globally change url strings and suffixes of the referenced files.
I think I can`t use "base href" because relative references (to files that are on the local server) would be affected.
I have a <input type = file> button for uploading a file in my php page. As soon as i select a file from the button, i need the file data to be displayed so that i check whether the file selected has the correct data. How can i do this.
I prefer to keep all my scripts in an external '.js' file. I am currently loading the external '.js' file from the header. Problem is I would like to declare a global variable in the external file, but I keep getting an error about the object does not exist.
Can someone tell me where or how to declare a global variable in an external file that is available after the page is loaded.
I've created a site where the pages generally contain a table of contents (site map) down the left side. When each page loads, the first function is called. The second function populates a global var (array) of all the links.
I try to avoid using global variables, but I am stumped how to eliminate this one (TocLinks) because other functions need to iterate through it. I think the answer is to create a custom object that the other functions can access. But I need some pointers on how to proceed.
Here's the function that the pages call initially and the 2nd function that it calls:
Is there a way to "pass" an XMLHttpRequest object to the callback function for onreadystatechange? Or a way to access it from onreadystatechange? I would like to avoid the use of a global variable...
Example:
/* How do I get rid of this global variable? */ xmlHttp = new XMLHttpRequest();
function myFunc() { ... xmlHttp.onreadystatechange = myCallBack; ... }
function myCallBack() { if (xmlHttp.readyState != 4) { return; }
I have a global variable which does not want to change : <header> .... <script type="text/javascript" language="JavaScript"> var i=1; function swap() { var window.i = 1 - window.i ; } ..... </script> .... <body>
I have a .js file that receives a value from an html page. I'd like this value to be a global variable that all functions in the .js file can use. I have tried just declaring a var at the top of my .js file, but when the value comes into the function and gets assigned to that variable, it is not global.
