Kendo Grid - In Firefox triggering an alert in the save event causes a page reload -


i want know if has seen this. have kendo grid , in save event, want validation. make sure new values difference between old less or equal balance.

so if greater balance, trigger alert , preventdefault. displaying alert causes page reload in firefox.

here grid:

$("#gridopeninvoices").kendogrid({         autobind: false,         datasource: openinvoicesdata,         scrollable: true,         sortable: false,         navigatable: true,         toolbar: [{name:"save",                    text:strings.applyupdates},                   {name: "splitpayment",                    text: strings.splitpayment},                   {name: "paidout",                    text: strings.paidout},                   {name: "createcredit",                    text: strings.creditbalance},                   {name: "undoallocation",                    text: strings.undoallocation}],         columns: [             {                 field: "customername",                 title: strings.accountname,                 hidden: true             },             {               field: "opentransactionid",               title: strings.opentransaction,               width:90             },             {               field: "invoicenumber"  ,               title: strings.invoicenumber,               width:65             },             {                 field: "grosssales",                 title: strings.originalamount,                 width: 75,                 format: "{0:c}",                 decimals: 2,                 min: 1,                 value: 0              },             {                 field: "balance",                 title: strings.transbalance,                 width: 75,                 format: "{0:c}",                 decimals: 2,                 min: 1,                 value: 0              },             {                 field: "date",                 title: strings.date,                 width:75,                 format: "{0:mm/dd/yy}"              },             {                 field: "age",                 title: strings.age,                 width:55              },             {                 field: "checknumber",                 title: strings.checknumber,                 width:85             },             {                 title: strings.applypayment,                 width:75,                 template: "<input class='k-chk-applied chkbox' type='checkbox' data-bind='source: isapplied' name='isapplied' #= isapplied ? 'checked' : ''#/>",                 attributes:{"class":"tdisapplied"}             },             {                 field:"appliedamount",                 title: strings.appliedamount,                 format: "{0:c}",                 width: 95,                 attributes: {"class" : "tdappliedamount"}             }], save: function(e) {     var model = e.model;     if (e.values.appliedamount != null) {         var remainingbalance = context.getremainingbalance();         var difference = e.values.appliedamount - model.appliedamount;         if (remainingbalance >= difference) {             var balancecopy = model.balancecopy;             model.balance = model.grosssales - e.values.appliedamount;             model.balancecopy = model.grosssales - e.values.appliedamount;              if (model.balance == 0 && model.isuncollected) {                 model.isuncollected = false;                 context.updatebalance(balancecopy, 0, true);             }             context.updatebalance(model.appliedamount, e.values.appliedamount, true);             this.refresh();             context.showbuttons();         }          else {             alert("the applied amount exceeds remaining balance");             e.preventdefault();         }     } }, editable:"incell"});

this seems happening when edit applied amount , hit enter commit. idea of why happening?

the solution simple: not use alert.

i have same problem in events in kendoui widgets. if need display user, use kendowindow it's modal property set true.

alerts should used debugging purposes, console.log.
