that.getCartList('subCart');

that.getCartList('addCart');

getCartList: function(handle) {

if(validList[j].valid[index].attrStatus && !validList[j].valid[index].is_gift){

if (['addCart', 'subCart'].includes(handle)) {

validList[j].valid[index].checked = false;

for (let k = 0; k < that.selectValue.length; k++) {

if (that.selectValue[k] == validList[j].valid[index].id) {

validList[j].valid[index].checked = true;

break;

}

}

if (validList[j].valid[index].checked) {

selectValue.push(validList[j].valid[index].id);

}

} else {

validList[j].valid[index].checked = true;

selectValue.push(validList[j].valid[index].id);

}
