在java脚本中从嵌套的n级数组/JSON对象中搜索对象

Question

我有一个带有嵌套列表的 JSON 对象。此列表中的每个元素也可以是嵌套列表。每个元素的深度可以达到 n 级。我需要遍历所有元素并获取与搜索条件匹配的对象。让我们说项目名称。如果我搜索应返回相应对象的项目名称。

列表结构

嵌套结构

Answer 1

function searchItemByName(sourceObject, name) {&nbsp; &nbsp; if (sourceObject['ItemName'] === name) {&nbsp; &nbsp; &nbsp; &nbsp; return sourceObject;&nbsp; &nbsp; }&nbsp; &nbsp; if (sourceObject['ChildrenBillOfMaterials']) {&nbsp; &nbsp; &nbsp; &nbsp; for (let i = 0; i < sourceObject['ChildrenBillOfMaterials'].length; i++) {&nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; let targetObject = searchItemByName(sourceObject['ChildrenBillOfMaterials'][i], name)&nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; if (targetObject !== null) {&nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; return targetObject;&nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; }&nbsp; &nbsp; &nbsp; &nbsp; }&nbsp; &nbsp; }&nbsp; &nbsp; return null;}

这是像日志所说的简单语法错误在 js 中以 { ... } 开头是不正确的。您的 JSON 对象有效但需要分配给对象实例。换句话说，您需要使用：var someObject = {...}try {var test = {&nbsp; "Description": "Rooftop heating/ cooling",&nbsp; "Category": "HVAC",&nbsp; "PartNumber": "MTU987456",&nbsp; "Quantity": "1",&nbsp; "Dimensions": "20(h)X20(b)",&nbsp; "BomID": "BOM-430",&nbsp; "Sublocation": "1st Floor",&nbsp; "GroupID": "BOM-430",&nbsp; "pxObjClass": "",&nbsp; "Custom3": "cust3 data",&nbsp;

Answer 3

您可以使用“.”继续查找子元素。&nbsp;$.each("jsonobj variable", function(index, element) {&nbsp; &nbsp;alert(element.description);&nbsp;&nbsp; });
