JavaScript in Firefox
2009-07-28 08:05:00
If we observe JavaScript becomes the usual programming language to design your websites. It is generally used for adding to features like sounds, videos, WebPages and other features such as menus, etc. Firefox has JavaScript enabled by default and therefore, you do not require installing it by hand. One problem is there with JavaScript. It can simultaneously do such things that many users do not want. Even though the settings of JavaScript in Firefox are configured to make your web use more protected, you are free to regulate these settings according to your preferences. Enabling or disabling JavaScript is very easy and simple. Firefox provides you the capability of choosing whether you allow the JavaScript in web pages to execute or not. The process for doing so is given below: a) Choose the tools menu from the toolbar situated on top of the Firefox window. b) When the options window pops up choose the control panel. c) Then you can choose the option to enable JavaScript if,...

Handy WordPress hack – changing javascript library location
2009-04-14 10:00:00
Here’s a little hack I worked out to solve a dilemma that didn’t appear to be particularly well documented. My problem was that I needed to use jQuery 1.3 for some script but the default version in WordPress 2.7 is v1.2.6. It also makes sense to load the library from a common source such as the Google Ajax Libraries API store which increases the chances of the site visitor already having a cached version of that file in their browser (decreasing the page load cost and consequently the page load time). Simply adding the script tag to the page header works, but any plugins or other WordPress functions which require jQuery will load the default copy of jQuery in addition to the one that you have added. Get a handle on it After digging around in the WordPress Codex and some other helpful blogs I managed to get to grips with the in-built system for loading javascript files. The way it works is that WordPress registers script libraries against defined ‘handles’. In...

How to enable JavaScript on your computer system
2009-01-05 19:27:00
JavaScript is a standard programming language for the World Wide Web. JavaScript programs are downloaded along with Web pages and run on your computer to provide functionality such as menus, sounds, and other interactive features. By default, Firefox enables the use of JavaScript on your computer system and requires no additional installation. However, JavaScript can also be used to do things that some users find undesirable. While the JavaScript settings in Firefox are configured to provide a safe experience on the web, they can be reviewed and changed. Web programmers can include JavaScript programs to make using their Web pages easier. JavaScript can enable links, edit data, help you fill in forms, and do many other useful things. Most complex sites, like Internet e-commerce and banking sites, use JavaScript. JavaScript is fundamentally safe.

Javascript - Access Denied When Calling Window Opener
2008-10-01 19:34:00
We usually use the "open" method in the window object to open a new window in Javascript. However, sometimes you need to change some values in the parent window depending on the changes of the new window elements values or you may need to call a method in the parent window from the child one. To do so, you can use the "opener" property in the window object to access the parent page elements. The following Javascript statement access an input element in the parent window with "txtEmail" ID and update its value:window.opener.document.ge-tElementById("txtEmail").value- = "mohammedn@mailhost.com";You can even call a method direct in the parent window from the new opened one:window.opener.SomeMethodInT-heParentWindow();However, you may get "Access Denied" or "Permission Denied" message when trying to access the "opener" property in the popup window. This usually because you call the window.open with the full path of the pop window:window.open('http://www.-domain.com/accounts/register_po-pup....

Verify calling Javascript function available to avoid runtime errors
2008-08-07 13:55:00
Do you want to verify whether a Javascript function exists before calling it to avoid runtime errors? With Javascript we used to call Javascript functions. But sometimes our Javascript code tend to throw runtime errors and showing then on the browser. For this there can be several reasons including; incorrect function names or invalid .js file names causing some functions not loaded into your web page. Javascript has the ability to check this. For that we can use the typeof keyword, and check whether that is of 'function' type or not.Generally we will be calling a Javascript function without checking whether it exists. Following code shows how we would call a function.function callClient(){ myTestFunction();}If the function named myTestFunction() is not available, the browser will show an error message at runtime. But we can check whether this method is available even before calling it, avoiding the errors. Following code snippet checks the existence before calling a function.f...
