Question

我现在有这个。

 //other stuff up here - not important
    echo "<td><form action='redeem.php' method='post' id='form'><input type='hidden' name='redeem' value='1' /><input type='hidden' name='id' value='" . $id . "' /><input type='submit' name='Redeem' value='Redeem'></form></td>";
    } else {
    echo "<td><form action='redeem.php' method='post' id='form'><input type='hidden' name='redeem' value='0' /><input type='hidden' name='id' value='" . $id . "' /><input type='submit' name='Un-Redeem' value='Un-Redeem'></form></td>";
//other stuff down here - not important

我想改变它，以便当你按下时：
a）“兑换”提交按钮，它会提醒您说：“您确定要兑换吗？”
b）“取消兑换”提交按钮，它会提醒您说：“您确定要取消兑换吗？”

我已经尝试了其中一些，包括提交上的ONCLICK但没有工作..我相信这是因为我在ECHO中有它并且我不得不删除阻止该功能发生的（“）引号

任何人都知道我能做到的另一种方式吗？

Answer 1

您可以使用Javascript确认功能。

if(confirm("Are you sure you want to Redeem?")) {
    // do something
} else {
    // do something
}

您也可以在表单提交时通过向表单添加以下代码来执行此操作：

onsubmit="return confirm('Are you sure you want to Redeem?');"

只有在用户点击“确定”时，表单才会提交。

以下是解决方案：

     //other stuff up here - not important
        echo "<td><form action='redeem.php' method='post' id='form'><input type='hidden' name='redeem' value='1' /><input type='hidden' name='id' value='" . $id . "' />
              <input type='submit' name='Redeem' value='Redeem' onclick="return confirm('Are you sure you want to Redeem?')"></form></td>";
        } else {
        echo "<td><form action='redeem.php' method='post' id='form'><input type='hidden' name='redeem' value='0' /><input type='hidden' name='id' value='" . $id . "' />
              <input type='submit' name='Un-Redeem' value='Un-Redeem' onclick="return confirm('Are you sure you want to Un-Redeem?')" ></form></td>";
    //other stuff down here - not important

修改在这里添加了转义字符：

//other stuff up here - not important echo "<td><form action='redeem.php' method='post' id='form'><input type='hidden' name='redeem' value='1' /><input type='hidden' name='id' value='" . $id . "' /> <input type='submit' name='Redeem' value='Redeem' onclick=\"return confirm('Are you sure you want to Redeem?')\"></form></td>"; } else { echo "<td><form action='redeem.php' method='post' id='form'><input type='hidden' name='redeem' value='0' /><input type='hidden' name='id' value='" . $id . "' /> <input type='submit' name='Un-Redeem' value='Un-Redeem' onclick=\"return confirm('Are you sure you want to Un-Redeem?')\" ></form></td>"; //other stuff down here - not important

Answer 3

使用javascript确认功能。如果确认返回false，表单将不会提交。

<form action='redeem.php' method='post' id='form' onSubmit="return confirm('Are you sure you want to redeem')">

如果您想在用户点击取消时执行其他操作，则需要创建自定义功能：

function my_confirm() {
    if( confirm("Are you sure you want to redeem?") ) {
        return true;
    }
    else {
        // do something 
        return false;
    }
}

在表格标签上：

onSubmit="return my_confirm()"

询问您是否确定要提交？ JavaScript的？
