Firebug is reporting that $ is not defined [Break On This Error] $(function(){ I have a simple index.php page that does a php include to include the contents I need. The contents are as follows: <script type="text/javascript"> $(function(){ $("#ipad").submit(function() { $.post("ipadcheck.php", $("#ipad").serialize(), function(data) { if(data.error == 'TRUE') { $("#results_ajax").html("<div class='AppleRedBold'>Sorry There were Errors: " + data.error_message + "</div>"); } else { $("#results_ajax").html("<div class='AppleRedBold'>" + data.display + " </div>"); } }, "json"); return false; }); }

I like making userscripts. It's real fun to get some more control of your favorite page or just speed up it's loading. Curently, I came across a problem that a page either defines console reference to a new dummy object: window.console = {log: function() {}, info: function() {} ... }; Or it even destroys the functions: window.console.log = function() {}; window.console.info = function() {}; ...

Also, I didn't use quick assigment to the same function on purpose, in the second example Now how would you deal with this?

Does anybody know how to suppress errors from being shown in browser console when executing dojo/request.

This is a code snippet var results = request.post("/webapp/target/save", { data: dojo.toJson(this._dataObject), headers: this.headers, handleAs: "json" }); There has to be a

Should I be using alert() for debugging; or is there a time to use alert() vs. console.log()? I see that alert() and console.log() can return different results. I assumed that they were similar functions but just returned in different places. Back story: my boss likes to see alerts() during development but I can't get the object details in the alert (at least not easily). But when I run the same request through console.log, I get the object and all of it's parameters. Since alert could be shown to users, it tends to be literal-minded (just using toString) so a developer has a lot of control
