我有一個像excel一樣工作的表格。用戶可以使用箭頭鍵導航整個表格。但是，當我試圖禁用它的一些文本框時，它仍然捕獲禁用的單元格，當我嘗試輸入文本時，該值正在可編輯單元格上添加。我怎樣才能解決這個問題？謝謝。使用箭頭鍵導航表格單元格並忽略禁用的單元格
這是我到目前爲止。
var active = 0;

var inp = String.fromCharCode(event.keyCode);
if (!(/[a-zA-Z0-9-_ ]/.test(inp) || event.keyCode == 96)) {
reCalculate(e);
rePosition();
// if key is an arrow key, don't type the user input.
// if it is any other key (a, b, c, etc)
// edit the text
if (e.keyCode > 36 && e.keyCode < 41) {
return false;
}
}

在HTML中是否有* Disabled *單元格。我看不到任何東西！ – Vikrant
我將禁用屬性使用javascript，因爲我綁定了我的文本框後端。 –
$（「＃input1，＃input3」）。prop（「disabled」，true）;我把它放在復位功能上。我想我把它放錯了:( –
