javascript - 用变量预填充 HTML 值？

Question

如何使 HTML 输入字段值预填充变量？在这种情况下，模态主体变量。 我阅读了有关使用 document.write 的信息，但我们如何将其与变量一起使用？

我们正在使用 Mandrill 和完整日历。
非常非常感谢!

代码:

 {
title: 'Event',
start: '2016-03-26T11:00:00',
end: '2016-03-26T12:00:00',
},
    ],
     eventClick: function(event) {
  console.log(event)
    // alert(event.start.format('MMMM Do YYYY'))
  var start = event.start.format('MMMM Do YYYY'),
    end = event.end.format('MMMM Do YYYY'),
    html = '<p>Starts: ' + start + '<p>';
  html += '<p>Ends: ' + end + '<p>';
  var modal = $("#modal");
  modal.find(".modal-title").html(event.title);
  modal.find('.modal-body').html(html)
  modal.modal();
    }
});
});
});//]]>

          </script>
        <script type="text/javascript"> 

          $(document).ready(function() {
// Generate a simple captcha
function randomNumber(min, max) {
    return Math.floor(Math.random() * (max - min + 1) + min);
}

function generateCaptcha() {
    $('#captchaOperation').html([randomNumber(1, 100), '+', randomNumber(1, 200), '='].join(' '));
}

generateCaptcha();

$('#contactForm')

不确定你的意思，可能是这样的？

modal.find('.' + modal-body)

但是变量不能有带“-”符号的名字..

“modal-body”等于“modal - body”，所以它会减去一个。
