javascript - 通过id提交表单的函数

Question

如何使用表单 ID 作为函数参数来提交表单？会是这样吗:

HTML:

<a href="#" onclick="confirmSubmit(form1)">Delete file</a>

Javascript:

function confirmSubmit(id) {
    var agree=confirm("Are you sure you wish to delete this file?");
    if (agree)
        document.getElementById('form' + id).submit();
    else
        return false;
}

Answer 1

您可以将表单 ID 作为字符串参数(即用单引号括起来)传递给 onClick 函数。

见下文

<a href="#" onclick="confirmSubmit('form1')">Delete file</a>
function confirmSubmit(id) {
    var agree=confirm("Are you sure you wish to delete this file?");
    if (agree)
      document.getElementById(id).submit();
    else
     return false;
}
