我正在嘗試根據 url 中的值過濾 json 數組并獲取屬性vernacularName。在 F12 調試中，我可以輸入record[0].vernacularName;它，它給了我正確的變量，但下面的代碼仍然失敗。document.getElementById("demo").innerHTML = datasetID;有效但document.getElementById("demo").innerHTML = vernacularName;無效。最終我想添加 vernauralName 作為會話變量<body> <div class=""> <h3>testing data</h3> <p id="demo" class = 'pl-5'></p> </div><script type="text/javascript"> const queryString = window.location.search; const urlParams = new URLSearchParams(queryString); const species = urlParams.get('species') const bone = urlParams.get('bone') const datasetID = urlParams.get('datasetID') var data; $.getJSON("json/data.json", function(json){ data = json; }); record = data.filter(r => r.datasetID == datasetID); var vernacularName = record[0].vernacularName; // const vernacularName2 = record.vernacularName; $_SESSION["v"] = vernacularName;</script><script>document.getElementById("demo").innerHTML = vernacularName;</script>
javascript根據url參數從數組中獲取屬性
