复选框全选与全不选效果
逻辑：复选框的checked属性与复选框全选效果对应起来，全选复选框checked：true 时，全部复选框checked：true；
全选框checked：false 时，全部复选框checked：false
function selectAll(){
var oInput = document.getElementsByName("cartCheckBox");
for(var i=0;i<oInput.length;i++){
oInput[i].checked=document.getElementById("allCheckBox").checked;
}
}
根据单个复选框的选择情况确定全选复选框是否被选
逻辑：全选复选框的checked属性对应全部单选复选框的checked；当全部单选框的checked：true时，全选复选框checked：true；
当全部单选框的某一个复选框checked：false时，全选复选框checked：false。
function selectSingle(){
var k=0;
var oInput = document.getElementsByName("cartCheckBox");
for(var i=0;i<oInput.length;i++){
if(oInput[i].checked==false){
k=1;
break;
}
}
if(k==0){
document.getElementById("allCheckBox").checked=true;
}
else{
document.getElementById("allCheckBox").checked=false;
}
}
