我有一些舊代碼正在嘗試瀏覽。該表是通過(guò)返回模型的控制器操作加載的，基于單擊頁(yè)面中其他位置的按鈕。如何在 JS 變量中找到表中的行數(shù)？我對(duì)JS很糟糕。我嘗試了一些方法，但沒(méi)有任何效果。下面是我的代碼以及我嘗試存儲(chǔ)行數(shù)的方法。桌子：<hr /><div class="row" id="ReceiptsMainDiv"> <div class="col-md-12" style="overflow-y:scroll"> <table class="table table-striped table-hover table-bordered" id="terminalReceipts"> <thead> <tr> <th>Terminal ID</th> <th>Local Transaction Time</th> <th>Amount</th> <th>Receipt</th> <td class="hidden"></td> </tr> </thead> <tbody> @foreach (var item in Model.TransactionsTests) { <tr id="@String.Concat("rowIndex", Model.TransactionsTests.IndexOf(item))"> <td>@item.TerminalID</td> <td>@item.TransactionTime</td> <td>@item.Amount</td> @*<td>@Html.ActionLink("View Receipt", "ViewReceipt", new { id = item.Id }, new { @class = "btn btn-primary btn-sm" }) <br /></td>*@ <td class="transactionID hidden">@item.Id</td> <td> @if (item.ReceiptData == null) { <button class="btn btn-sm btn-primary viewReceipt" disabled>View Receipt</button> } else { <button class="btn btn-sm btn-primary viewReceipt" data-rowindex="@String.Concat("rowIndex", Model.TransactionsTests.IndexOf(item))">View Receipt</button> } </td> </tr> } </tbody> </table> </div>這是我在 JS 中嘗試做的事情：var rowId = "#" + $(this).data("rowindex"); var row = $(rowId); console.log(rowId); console.log(row);console.log 的結(jié)果似乎不準(zhǔn)確。任何事情都有幫助。謝謝

也許您想要表格的行數(shù)。
// javascript
var rowsInTable = document.getElementById("terminalReceipts").getElementsByTagName("tr").length;
//jquery
var rowsInTable2 = $("#customers").children('tbody').children('tr').length;
//if you need to do something with the rows:
var rows = $("#customers").children('tbody').children('tr');
rows.each(function( index ) {
console.log( index + ": " + $( this ).text() );
});

你也可以像這樣使用 jquery 來(lái)做到這一點(diǎn)
var totalRowCount = $("#terminalReceipts tr").length; //this will give +1 row
var rowCount = $("#terminalReceipts td").closest("tr").length; //this will give actual row
