underscore.js,js工具库
官方文档：http://underscorejs.org/
var totalCheckPriceVal = _.reduce(tableData[0],function(memo,num){
var memoint=memo-0;
var numint=num-0;
return memoint+numint; },0
)
_.reduce()
计算一个数组里所有值相加
var selectProdutData = _.indexBy(prodcutList,function(obj){
return obj.originalProductCode+obj.stationCode+obj.orderNumber;
});
._indexBy()
返回一个key-value形式的js对象可用于添加商品业务逻辑的实现；
_.map(productsData,function(product){
var objNegative={};
if((product.confirmedNumber-0)<=0){
isNegative=true;
objNegative.originalProductCode=product.originalProductCode;
objNegative.stationCode=product.stationCode;
objNegative.orderNumber=product.orderNumber;
arrayNegative.push(objNegative);
}
})
._map()
一个遍历函数；
遍历的时候遇到异步执行的函数会同步执行；
使用underscore制作一个打印分页html
