Or, press and hold Ctrl (Windows, Linux) or Command (macOS), and then click the link. There is no requirement to perform this task manually in JavaScript.

Open the demo webpage Get Started Debugging JavaScript in a new window or tab. In debugging, generally we set breakpoints to examine each line of code step by step.

If two or more lines contain the same code, and you set a breakpoint on one of those duplicate lines, the breakpoint mapping algorithm might select the wrong duplicate in the client-side file. The first step in debugging is to find a series of actions that consistently reproduce a bug. The algorithm assumes that each line is unique.

To find the corresponding location in the server-side and client-side script, the breakpoint mapping algorithm examines the code on each line. The breakpoint must be set in the page with the php file extension. We recommend placing your javascript code into a separate js file.īreakpoints set in blocks cannot be mapped.įor breakpoints set in blocks, breakpoint mapping ignores the id attribute. The breakpoint must be set in the page specified in the browser URL, not in another file included by that page.īreakpoints set in included pages cannot be mapped. Breakpoint mapping cannot recognize a redirection from an address such as to the default page. The browser URL for the page must contain the page name. Breakpoints in inline script or blocks cannot be mapped. Visual Studio maps the breakpoint from the server-side file to a corresponding breakpoint in the client-side file, subject to the following limitations:īreakpoints must be set inside blocks. Visual Studio enables you to set a breakpoint in a server-side PHP script that is transformed to a client-side file at run time.

In VS2012 and higher user can choose active browser from browser switcher.

In VS2010 the system default browser is used.

When a PHP Web project is launched in debug mode and Internet Explorer is used as browser, PHP Tools will automatically attach the client-side script debugger. The JavaScript debugger allows you to view the JavaScript scripts that are loaded into the browser with the web page. Visual Studio automatically maps the breakpoint to a corresponding location in the client-side file and creates a mapped breakpoint in the client-side code. In Visual Studio, you cannot directly debug server-side code, but you can set a breakpoint in a server-side file. For more information, see How to: View Script Documents. Any script document can be opened from the Solution Explorer.

In Visual Studio, you can use the Solution Explorer to see the lists of server-side and client-side script documents. For more information, see How to: Enable and Start Script Debugging from Internet Explorer. Enabling Script Debuggingīefore you are able to begin debugging script with Visual Studio, the script debugging must be enabled in Internet Explorer. PHP Tools for Visual Studio provides a debugging environment for finding and correcting errors in client-side scripts in PHP pages.
