jquery check box selected, Canceled, select all, no problem

First, the jquery library must be  introduced:
Here is the JS code:

 /** * service management block >>> check box event handling*/    //Service Management check box is selected, canceled
$ (function () {

$ ("#ServiceManageMent"). Click (function(){        if( This. Checked) {            $(". Checkb3"). each (function(){                 This. checked =true; $( This). Val (1);        }); }Else{            $(". Checkb3"). each (function(){                 This. checked =false; $( This). val (0);        });    }    }); //service creation is selected, canceled$ ("#serviceCreate, #serviceDispatch, #serviceDeal, #serviceArch, #serviceFeedback"). Click (function(){        var$serviceCreate = $ ("#serviceCreate"). Is (": Checked"); var$serviceDispatch = $ ("#serviceDispatch"). Is (": Checked"); var$serviceDeal = $ ("#serviceDeal"). Is (": Checked"); var$serviceFeedback = $ ("#serviceFeedback"). Is (": Checked"); var$serviceArch = $ ("#serviceArch"). Is (": Checked"); if( This. Checked) {            //If service creation is selected, determine if the other check boxes are selected, and if they are selected, change the selected state of service management            if($serviceCreate) {$ ("#serviceCreate"). Val (1); }Else{                $("#serviceCreate"). Val (0); }            if($serviceDispatch) {$ ("#serviceDispatch"). Val (1); }Else{                $("#serviceDispatch"). Val (0); }            if($serviceDeal) {$ ("#serviceDeal"). Val (1); }Else{                $("#serviceDeal"). Val (0); }            if($serviceFeedback) {$ ("#serviceFeedback"). Val (1); }Else{                $("#serviceFeedback"). Val (0); }            if($serviceArch) {$ ("#serviceArch"). Val (1); }Else{                $("#serviceArch"). Val (0); }            if($serviceCreate && $serviceDispatch && $serviceDeal && $serviceFeedback &&$serviceArch) {                $("#ServiceManageMent"). each (function(){                     This. checked =true;            }); }Else{                    $("#ServiceManageMent"). each (function(){                         This. checked =false;                }); }        }Else{            $( This). val (0); $("#ServiceManageMent"). each (function(){                 This. checked =false;        }); }    });

});
    

JSP page Core code:

Notes:

jsp file, you will see " <s:if test="%{#request. R.servicecreate ==1} ">" This code, do not doubt, This is the label and expression of Struts2,

Ignore it, though the code is a little bit heavier in thought. Each road God, please give more advice!
