Confirm Save During Onchange Of Drop Down

Onchange of select option I am confirming the user whether to save or not the changes. If user selects OK , I am submitting the form automatically.ie. onchange='if(confirm('Save?')

Solution 1:

Try this, don't think you can accomplish it without some manual work.

<scripttype="text/javascript">var ddHelper = {
    previousIdx: null,
    store: function(e, dd) {
        this.previousIdx = dd.selectedIndex;
    },
    confirm: function(e, dd) {
        if(!window.confirm('Save?')) {
            window.setTimeout(function() { // Think you need setTimeout for some browsers
                dd.selectedIndex = ddHelper.previousIdx;
            }, 0);
        }
    }
};
</script><selectonfocus="ddHelper.store(event, this)"onchange="ddHelper.confirm(event, this"></select>

Solution 2:

If the input values come from any Database, load those again in the field when user press cancel.
