询问您是否确定要提交？JavaScript的？

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,以便当您按下:
a)"兑换"提交按钮时,它会提醒您说:"您确定要兑换吗？"
b)"Un-Redeem"SUBMIT按钮,它会提醒您:"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,但没有一个工作..我相信这是因为我在ECHO中有它,我不得不删除阻止该功能发生的(")引号.

有人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
}

您也可以通过在表单中​​添加以下代码在表单提交上执行此操作:

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.

这是解决方案:

     //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

编辑: 在这里添加转义字符:

 //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
