javascript - 引导模式不会启动

问题描述

模态不显示我的任何图像。我尝试更改图片和代码。但是我对此很陌生，我不知道。可能是javascript还是代码本身？我已经尝试过 atom 和 Dreamweaver，但我遇到了同样的问题。

$(function() {
    $('#site-modal').on('show.bs.modal',function() {
        $(this) 
               .find('.modal content img')
               .attr('src',$(event.relatedTarget).data('highres') )
    });                                     
});

圆顶排序的图像链接损坏。

$(function() {

  $('#site-modal').on('show.bs.modal', function() {
    $(this)
      .find('.modal content img')
      .attr('src', $(event.relatedTarget).data('highres'))
  });
});

解决方案

这个元素不存在 find('.modal content img')

你有“.modal-content img”这个
