javascript - Question on tabbing to next NON-READONLY field -


on blur of field1, field2 set readonly cursor on page defaults field2 , cursor located @ end of value , when user clicks backspace button value can erased. ability have cursor move next non-readonly or enabled field on page. do-able jquery?

any help/direction appreciated. thank you.

here code:

[code] $(function() {            $("#artransferform\\:fromaccountamt").blur(function() {                var origaccountamount = $("#artransferform\\:fromaccountamt").val();                var fromaccountamount = $("#artransferform\\:fromaccountamt").val();                // call validation "r2" function                            var modfromaccountamount = r2(fromaccountamount);                //alert("modfromaccountamount = " + modfromaccountamount);                fromaccountamount = $("#artransferform\\:fromaccountamt").val(modfromaccountamount).val();                //alert ("modified fromaccountamount = " + fromaccountamount);                if (modfromaccountamount != "n.an") {                    var firstchar = fromaccountamount.charat(0);                    var fromacctamtlen = $("#artransferform\\:fromaccountamt").val().length;                    if (firstchar == "-") {                        var revfromacctamt = fromaccountamount.substring(1, fromacctamtlen);                        $("#artransferform\\:toaccountamt").val(revfromacctamt);                        $("#artransferform\\:toaccountamt").attr("readonly", "readonly");                    } else {                        $("#artransferform\\:toaccountamt").val("-"+fromaccountamount);                        $("#artransferform\\:toaccountamt").attr("readonly", "readonly");                                     }                } else {                    $("#artransferform\\:fromaccountamt").val(origaccountamount);                    $("#artransferform\\:fromaccountamt").select();                    alert("invalid amount format. use ##.## (no commas or $ sign)");                }            });        }); [/code]

have tried modifying tabindexes onblur, before return true, control cursor goes? it's kind of hack, there go.

also, use delegated event (perhaps on form) intercept , return false on keypress events modify value of readonly input. like:

$('#artransferform *[readonly]').live("keypress", function(event) {     // compare keycode blacklist: backspace, perhaps delete too?     if(bkeyisblacklisted) {         event.preventdefault();         return false;     } });

(note: pretty pseudocodeonous. you'll want double-check syntax sizzle's attribute selectors, jquery's event delegation signature. , real careful how wide cast "no keys" net: try avoid disallowing copy , other operations performed keyboard shortcuts. need check modifier key distinguish between user trying type "c" , ctrl+c.

which browser(s) testing in?
