Question

我想使用JavaScript添加确认框。所以，这是我用过的代码。当我单击“删除”按钮时，它会向我显示“确认”消息，当我单击“确定”时，它不会删除我的行。

这有什么问题？我该如何解决这个问题？

a table

这是索引页

Answer 1

将ID更改为＆＃39; delid＆＃39;。您将该函数称为deleteme(delid)。所以你必须使用delid而不是id。

 function deleteme(delid)
 {
 if(confirm("Do you want Delete!")){
 window.location.href="AdminDel.php?id="+delid; /*Change id to 'delid'*/
 return true;
 }
 }

Answer 2

使用 window.location.href 而不是window.location

Answer 3

您的功能有几个问题：

function deleteme(delid) {
    if(confirm("Do you want Delete!")){
        window.location="AdminDel.php?id='+id+'";// this should be delid, also bad quotes, also you want to set the href, not the location
        return true;
    }
}

修正：

function deleteme(delid) {
    if(confirm("Do you want Delete!")){
        window.location.href="AdminDel.php?id=" + delid; 
        return true;
    }
}
