- I want to validate whether the approach I am taking with error messages is crazy, or if it's within reason.My understanding of jquery mobiles page error handling is the following:jQueryMobile has a default way of notifying the user that a pageload failed. By default it comes up with "Error Loading Page".The following are the only interactions a developer using jQueryMobile has with these errors.1) Changing the text/theme in mobile init
- $(document).on('mobileinit', function () {
- $.extend($.mobile, {
- pageLoadErrorMessage: 'blah',
- pageLoadErrorMessageTheme: 'b'
- });
- });
2) pageloadfailed event- $(document).on('pageloadfailed', function (event, data) {
- //ok, i know it failed, now what? reject the promise? prompt my own error? change the global error message here?
- });
It would seem that there isn't a more convenient way of interacting with the error? Is the expectation in option 2) that you'll change the global error message inside the event?I want to change the error message based on the situation, because sometimes I have context information that I want to provide a user which is more than "Sorry, we're having issues" or "Error Loading Page".The approach I am taking at the moment is this:- $(document).on('pageloadfailed', function (event, data) {
- $.mobile.loading( 'hide' );
- data.deferred.reject( data.absUrl, data.options );
- //do my own thing here, alert with a popup with options
- });
It essentially follows what the jquerymobile code does internally anyway, but with my custom error popup instead of the default one. Here's the jqmobile (1.2) code (lines 3741-3753, comments removed):- if ( settings.showLoadMsg ) {
- hideMsg();
- $.mobile.showPageLoadingMsg( $.mobile.pageLoadErrorMessageTheme, $.mobile.pageLoadErrorMessage, true );
- setTimeout( $.mobile.hidePageLoadingMsg, 1500 );
- }
- deferred.reject( absUrl, options );
I know there is that "showLoadingMsg" option, but I still want the general ajax loader and i'm not sure there is a way to change this behavior when clicking on a link (seems to only be available when calling #changePage directly).Anyway, sorry about the long post. But the ultimate goal is to see if what I am doing is reasonable, or totally insane.Thanks!- As some background, I have a jQuery Mobile app where each url is fully loadable as jquery html pages, but they also have the capacity to return a json response instead.Is there any way to tap into jQuery Mobile's url changing functionality without actually transitioning to a new page? I know that isn't a very jQuery Mobile-ish thing to do, but jQuery Mobile has really nice cross-browser url changing behavior, and there are a couple places where I would like to load some content, change the url, but not actually change the page (particularly since the app behaves like a single page app overall, so there are times where there is a ton of redundancy in reloading the entire page).I know about #changePage() and #loadPage(), but change page is a full page change (not what I want) and #loadPage doesn't change the url (plus, i'm looking for a slimmer json response in these cases, and loadPage is gonna load the whole html payload and inject it into the DOM).Any advice?Thanks!
