That quote in itself should prove that onload should not be relied on if you want the full DOM to be loaded properly before you start manipulating it. It is an incredibly popular mistake to use load where DOMContentLoaded would be much more appropriate, so be cautious. A very different event - load - should be used only to detect a fully-loaded page. The DOMContentLoaded event is fired when the initial HTML document has been completely loaded and parsed, without waiting for stylesheets, images, and subframes to finish loading. The Mozilla Developer Network states on this page: The common misconception of using window.onload will not fix the issue where the elements have not loaded in correctly. JavaScript can be loaded before or after the HTML, however the way it is done is slightly different depending on how you do it.įor example if you wish to include your JavaScript files within the head of the HTML file then you must wrap your JavaScript code with either DOMContentLoaded or jQuery's $(document).ready(). Removing it or including it throws an error. It's the equivalent to the cordova.js (aka phonegap.js) file that is inserted into your project when you do a Cordova (aka PhoneGap) build. It's not working, BUT I'm not getting the errors I was before, except for the missing/unnecessary semicolon paradox. 1 Answer Sorted by: 0 The file is not part of your project this file is injected automatically when your app is run inside the emulator or when it is built. This includes the alert() function which I don't think I've ever seen needing to be declared that way, but I gave the code editor what it wanted and this last screenshot is the results. So the problem I went on to have is that unless every function or dom object was declared with "Var", I'd get an error. I included this screenshot to show my work before I made the changes. Once I did that and accessed it through dot syntax instead of an equal sign then I stopped getting the error. So I've tried a few things and it's still not working but I HAVE managed to get my errors down to just one inexplicable "missing semicolon", which will turn into an "unnecessary semicolon" error if I place it.Īny way as per the first screen shot you'll see that I wasn't placing the document object inside of an explicitly declared variable. My path is: js/Test.js and it's the last script tag before the body. I've considered that my script tag src path in the index file is incorrect, but all the paths are relative in the commented out template script tags intel provides on the index page right out of the box, so why would I have to use an absolute path? I'm getting "document not defined" and "alert not defined" errors or the js page though. I know the syntax is correct because it works when I put it in tags in the index.html file. I've included a screen shot of test code and the errors. I'm just setting up my file tree and making sure the html and javascript pages are connected via the right anchors and script paths. I'm starting fresh with a new blank Intel project and I haven't even started coding yet.
