Question

我有一個頁面，我可以通過window.open方法調用另一個彈出窗口。我如何能在揭幕戰網頁更改標籤從彈出頁面，同時彈出的頁面仍然活着就是唯一未閉尚未

Answer 1

它應該是這樣的：

window.opener.document.getElementById('label1').value = "the new value"; 

Answer 2

這是更好地讓opener窗口通過將小API暴露給彈出窗口來處理更改值。

Answer 3

<script> 
function myFunction() { 
    var additionalWindow = window.open("/additional"); 

    // Write on the additional window 
    additionalWindow.document.write('written from separate window'); 

    // Call a function on the additional window 
    additionalWindow.someFunction(); 
} 
</script>
