easyui validate -- radio、checkbox 校验扩展

1、extension.js:

$.extend($.fn.validatebox.defaults.rules, {
    radio: {  
        validator: function(value, param){  
            var input = $(param[0]),status = false;
            input.off(‘.radio‘).on(‘click.radio‘,function(){
                $(this).focus();
                try{ cntObj.tooltip(‘hide‘); }catch(e){}
            });
            var firstObj = $(input[0]),cntObj = firstObj.parent(),initCount = cntObj.attr("initCount") || 0;
            cntObj.off("mouseover mouseout").on("mouseover mouseout",function(event){
                var bool = input.validatebox(‘isValid‘);
                if(event.type == "mouseover"){
                    if(bool) try{ cntObj.tooltip(‘hide‘); }catch(e){}
                    else try{ cntObj.tooltip(‘show‘);}catch(e){}
                }else if(event.type == "mouseout") try{ cntObj.tooltip(‘hide‘); }catch(e){}
            });

            var tipMsg = firstObj.validatebox.defaults.missingMessage || firstObj.validatebox.defaults.rules.checkbox.message;
            if(initCount-1<0){
                firstObj.parent().tooltip({
                    position: ‘right‘,
                    content: ‘<span style="color:#fff">‘+tipMsg+‘</span>‘,
                    onShow: function(){
                        $(this).tooltip(‘tip‘).css({
                            backgroundColor: ‘#666‘,
                            borderColor: ‘#666‘
                        });
                    }
                }).tooltip(‘hide‘);
                initCount = initCount - 0 + 1;
                cntObj.attr("initCount",initCount);
            }

            status = $(param[0] + ‘:checked‘).val() != undefined;
                
            return status;
        },  
        message: ‘Please choose option for {1}.‘  
    },
    checkbox: {
        validator: function (value, param) {
            var inputs = $(param[0]), maxNum = param[1], checkNum = 0,status=false;
            inputs.each(function () { 
                if (this.checked) checkNum++;
            });
            inputs.off(‘.checkbox‘).on(‘click.checkbox‘,function(){
                $(this).focus();
                var bool = inputs.validatebox(‘isValid‘);
                if(bool) $(this).parent().tooltip(‘destroy‘);
                else {
                    var tipMsg = $(this).validatebox.defaults.missingMessage || $(this).validatebox.defaults.rules.checkbox.message;
                    $(this).parent().tooltip({
                        position: ‘right‘,
                        content: ‘<span style="color:#fff">‘+tipMsg+‘</span>‘,
                        onShow: function(){
                            $(this).tooltip(‘tip‘).css({
                                backgroundColor: ‘#666‘,
                                borderColor: ‘#666‘
                            });
                        }
                    }).tooltip(‘show‘);
                }
            });
            status = checkNum > 0 && checkNum < 4;
            return status;
        },
        message: ‘Please choose options !‘
    }
});
