使用下划线js对对象数组进行排序

Question

我有如下对象数组：

profData=[{"Details":{"CODE":"PAT4PAS","DESCRIPTION":"PASTIE 4N20 12 X 175G","LOCATION":"FREEZER","UNITS":"BOX","WAREHOUSE":"00","AVAILABLE":"15.0000","ON_HAND":"15.0000","BRAND":"4N20","PRICE1":"18.80","TAX_CODE1":"1","PROD_CLASS":"FROZ"}},{"Details":{"CODE":"PAT4PAS","DESCRIPTION":"PASTIE 4N20 12 X 175G","LOCATION":"FREEZER","UNITS":"BOX","WAREHOUSE":"00","AVAILABLE":"15.0000","ON_HAND":"15.0000","BRAND":"4N20","PRICE1":"18.80","TAX_CODE1":"1","PROD_CLASS":"FROZ"}},{"Details":{"CODE":"OMKM","DESCRIPTION":"SAUCE KETCHUP MANIS 620ML [6]","LOCATION":"DRY","UNITS":"EACH","WAREHOUSE":"00","AVAILABLE":"187.0000","ON_HAND":"189.0000","BRAND":"ABC","PRICE1":"3.40","TAX_CODE1":"-1","PROD_CLASS":"DRY"}},{"Details":{"CODE":"BAXSAL","DESCRIPTION":"SALSA MEXICAN 2LTR [6]","LOCATION":"DRY","UNITS":"EACH","WAREHOUSE":"00","AVAILABLE":"439.0000","ON_HAND":"445.0000","BRAND":"AGE","PRICE1":"9.20","TAX_CODE1":"-1","PROD_CLASS":"DRY"}},{"Details":{"CODE":"BAXSEMI","DESCRIPTION":"TOMATO SEMI DRIED 2KG [4]","LOCATION":"REFRIDGERATOR","UNITS":"EACH","WAREHOUSE":"00","AVAILABLE":"55.0000","ON_HAND":"59.0000","BRAND":"AGE","PRICE1":"21.10","TAX_CODE1":"-1","PROD_CLASS":"CHILL"}},{"Details":{"CODE":"BAXSUN","DESCRIPTION":"TOMATO SUN DRIED 2KG [4]","LOCATION":"REFRIDGERATOR","UNITS":"EACH","WAREHOUSE":"00","AVAILABLE":"39.0000","ON_HAND":"39.0000","BRAND":"AGE","PRICE1":"15.20","TAX_CODE1":"-1","PROD_CLASS":"CHILL"}},{"Details":{"CODE":"AMFBAM","DESCRIPTION":"FLOUR - AM SUP BAKERS 12.5KG","LOCATION":"REFRIDGERATOR","UNITS":"BAG","WAREHOUSE":"00","AVAILABLE":"259.0000","ON_HAND":"339.0000","BRAND":"ALLIE","PRICE1":"13.70","TAX_CODE1":"-1","PROD_CLASS":"CHILL"}},{"Details":{"CODE":"ALPKKC","DESCRIPTION":"KRANSKY - CHEESE 2.5KG [6]","LOCATION":"REFRIDGERATOR","UNITS":"EACH","WAREHOUSE":"00","AVAILABLE":"27.0000","ON_HAND":"27.0000","BRAND":"ALP","PRICE1":"19.30","TAX_CODE1":"-1","PROD_CLASS":"CHILL"}},{"Details":{"CODE":"ABTDP","DESCRIPTION":"TOOTHPICK - DOUBLE POINT 1000","LOCATION":"DRY","UNITS":"EACH","WAREHOUSE":"00","AVAILABLE":"12.0000","ON_HAND":"12.0000","BRAND":"ALPEN","PRICE1":"1.60","TAX_CODE1":"1","PROD_CLASS":"DRY"}}]

我想用PROD_CLASS对其进行排序，

我用下划线js试过了，但没有得到解决。

var fullySorted = _.sortBy(profData, 'PROD_CLASS');

但它没有使用PROD_CLASS 排序。

谁能帮帮我。

提前致谢。

Answer 1

由于PROD_CLASS 不是数组元素的直接属性，这将不起作用。

_.sortBy(profData, obj => obj.Details.PROD_CLASS);

这是一样的

_.sortBy(arr, function(obj) {
    return obj.Details.PROD_CLASS;
});

var profData = [{
