javascript exception catching and error printing
I hate seeing JavaScript errors on pages, especially on my pages, so in this case I have to run JavaScript debugger to catch the exact line there the problem is. If I change a function with many exceptions, a better solution exists: printing JavaScript errors with alert function (we firstly handle the error and then we print it): try{ ... do some javascript here ... } catch (e) { try{ var ex_joro = e; // this is to remember to set the exception name :) var errorString = ex_joro.name + ' ' + ex_joro.message + ', fileName = ' + ex_joro.fileName + ', lineNumber = ' + ex_joro.lineNumber + ", stack: " + ex_joro.stack + ",\n\n all: " + ex_joro ; // this is used when you do javascript debugging alert( errorString ); } catch ( exception_666 ){ alert( "exception while trying to alert exception " + exception_666 ); } }
