Based on a work at www.
For example, you may want to quickly debug JScript, investigate a behavior specific to Internet Explorer, or iterate rapidly to prototype a new design or try solutions to a problem.
Integrated and simple to use: In addition, the tools only load when needed to limit the impact of the tools on browser performance. Using the Developer Tools, Internet development can do on-the-fly script debugging for only the current Internet Explorer process rather than enabling debugging for all of Internet Explorer.
Provide a visual interface to the platform: Instead of reverse engineering how your site works or modifying your site to output debug information, the Developer Tools let you look into Internet Explorer to view its representation of your site. When prototyping a new design or testing fixes in previous versions of Internet Explorer, you likely edit your source, save it, refresh your page in the browser, and repeat.
Identifying and fixing performance issues is usually an iterative approach done by focusing on one scenario at a time. With these characteristics, the features of the Developer Tools will dramatically improve your productivity when developing in Internet Explorer.
The rest of this article explains many of these and other features in more detail. Getting Started Getting started with the tools is simple: Once open, the tools exist in their own window, Internet development one connected to a single tab in Internet Explorer.
Some features of the tools do not need the complete tools interface. The tools become a row at the bottom of the window, providing access to just the Command Menu bar. You can navigate the tree with the mouse or the keyboard.
The quickest way to find the node for a specific element on the page is to use the Select Element by Click feature.
Use this feature to select an element on the page and the tools will automatically select the corresponding tree node. An alternative method is to use the Search box.
The Style command improves CSS debugging by providing a list of all rules that apply to the selected element.
The rules display in precedence order so those that apply last appear at the bottom and any property overridden by another is struck through, allowing you to quickly understand how CSS rules affect the current element without manually matching selectors.
You may quickly turn a CSS rule on or off by toggling the checkbox next to the rule and the action will take effect immediately on your page. This command contains the same information as Style except it group styles by property.
If you are looking for information about a specific property, switch to Trace Styles command. The Attributes command allows you to inspect all defined attributes of the selected element. This command also allows you to edit, add or remove attributes from the selected element.
Select a style sheet by clicking on the Style Sheet Chooser button. Clicking on a style property name or value allows you to change it and see it take effect immediately.
Editing Sources On-The-Fly After using the tools to inspect and gather the information you needed, you may want to take action on your findings right away.
The change takes effect immediately so you can quickly test changes. In HTML, you can also press the Edit button to make the entire tree editable and then add, remove, or edit complete elements.
In either case, the Developer Tools enable quick editing without modifying your source. Once you get everything to where you want it, you can save your changes. Therefore, refreshing the page or navigating away brings back the original site.
However, in some cases you may want to save the changes. Remember that not only will the areas of your site that you modified differ from your source, but other parts may also differ since the tools display your site as it exists in Internet Explorer rather than in your source.
To prevent accidentally overwriting source, the tools save the output as text and add a leading comment to the file. And as with any programming language, a good debugger is critical to being productive and the Developer Tools provide just that. On any site you want to debug, open the Developer Tools and switch to the Script tab, then click Start Debugging.
When starting the debugging process, the Developer Tools will Refresh the page and Unpin the tools if it is pinned.
Anecdotal Internet History showing the increasing development of friendly utilities, menus, and search engines driven by rapid expansion and the demand for convenience and ease of use by less sophisticated users, businesses, and communities of interest. Internet development is about people. Shared knowledge and collaborative relationships are key drivers of successful Internet growth, not technology alone. The Internet Society works to foster growth and access to technology by bringing information, training, and partnerships to people and communities across the globe. The history of the Internet begins with the development of electronic computers in the s. Initial concepts of wide area networking originated in several computer science laboratories in the United States, United Kingdom, and France.
Once started, you have all the functionality you expect from a debugger. Once you are done, click the button again to Stop Debugging. While the debugger is started, the Developer Tools offer powerful control and insights into your scripts. Controlling Execution You can pause execution at a specified place by setting breakpoints.
