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
