当用户按下“插入”键时，如何提交表单？

Question

How can I prompt for confirmation before submitting a form after they press the Insert key, and submit the form without confirmation when the user pushes the Enter/Return key ?

Summary of actions intended

• INSERT : Prompt for confirmation. Submit form if confirmed.
• ENTER : Submit form.

I have the following html form :

<form action="hhhhhhh.php" method="post" >
   <input type="text" name="DatInvNew"/>
   <input type="text" name="SumInvNew"/>
   <input type="text" name="KolInvNew"/>
   <input type="submit" value="next"/>
</form>

Answer 1

The following example does these things (as per the original question) :

• INSERT : Prompt for confirmation. Submit form if confirmed.
• ENTER : Submit form.

document.onkeypress = function (e) {
    e = e || window.event;
    if(e.keyCode == 45) {
        if(confirm("Would you like to submit this form?")) {
            document.getElementById("myForm").submit();
        }
    } else if (e.keyCode == 13) {
        document.getElementById("myForm").submit();
    }
};

And change your html slightly :

<form action="hhhhhhh.php" method="post" id="myForm">
    <input type="text" name="DatInvNew"/>
    <input type="text" name="SumInvNew"/>
    <input type="text" name="KolInvNew"/>
    <input type="submit" value="next"/>
</form>
