I could change that line to g_form.getValue(‘assigned_to.manager’), but that wouldn’t work either because the client script triggers when the Assigned to field is changed, not when the dot-walked Manager field is changed. This means that my g_form.getValue(‘manager’) line would not work. In this case, the issue is being caused by the fact that the Manager field is a dot-walked field. Now that the debugger has helped us figure this out, we might go and investigate why this is. This is causing the script to return early, and not do what I expected it to do. I can use the buttons at the top-right of the debugger to step line-by-line through my code, or even into or out of a given function-call, or I can use step over to remain at the current level of the call stack (meaning, keep the debugger on my code).īy advancing step-by-step through my code, I can see that it’s evaluating my if block to be true, because assigneeMgrID is blank. Since the code paused after that variable was assigned, we would expect that variable to have a value! that’ll show you the values of the variables in your code at the moment the code halted.Īs you can see in the image to the right, the variables in the local function scope in my code look as you’d expect, except for assigneeMgrID. In the Scope section, Local is usually going to be the most relevant bit. Collapse Call Stack, and you’ll see Scope. By default (in Chrome), this will be just below the Call Stack section on the right side of the debugger. This can all look pretty overwhelming at first, but the main thing to pay attention to, is the Scope section. Join me after the jump, for a walk-through! In this short article, we’re going to see exactly how to do that, using a not-very-smart Client Script that runs on the Incident form. In fact, you can! Better yet, you can put calls to the debugger directly in your code! The question then becomes: “ How do I trigger the client-side debugger? I can’t easily put breakpoints in my code that runs client-side, especially if it runs on-load right?” The good news is, modern browsers already have an incredible debugger that’s at least as good as the server-side script debugger in ServiceNow, built right in! So, how do you troubleshoot client-side scripts in ServiceNow? Well, since those scripts execute inside the user’s browser, you’re going to have to use some browser-magic to make that happen. When available, that tool is incredibly useful but unfortunately, it does not work with client scripts. Normal ServiceNow function to output text to the syslog database table as an ERROR.When dealing with server-side scripts, the ServiceNow Debugger makes debugging relatively easy (most of the time), as you can actually see into the call stack, and the contents of your server-side variables as you step through your code, line-by-line. Normal ServiceNow function to output text to the syslog database table as a WARNING. Normal ServiceNow function to output text to the syslog database table. Similar to gs.addInfoMessage(String) but only outputs if user has sp_admin role or is impersonating. Can log server-side JavaScript Objects and Strings. When used in the Server Script, can log server-side JavaScript Objects and Strings Native to Chrome and Firefox to set a browser breakpoint, letting an admin step through script line by line Uses Angular json filter to display content of data object in an easy-to-read fashion When used in the Client Controller, this command is native to the browser.Īdd this to the template.
